Description

  The present invention relates to a game apparatus, a game apparatus control method, and a program that are suitable for supporting the improvement of a player in a game in which a player performs an operation input in accordance with the reproduction of music.

  A so-called music game (rhythm game) in which a player operates input in accordance with the rhythm of music is known. For example, a music game is a game that progresses when a player inputs in a timely manner when instruction images sequentially displayed on a screen reach a reference image. As the player inputs the operation instructed by the instruction image in a timely manner, the player can perform an operation in accordance with the rhythm of the music (dance choreography, musical instrument performance, etc.) and enjoy the game.

  In such a music game, the game is typically scored based on a difference between the timing indicated by the instruction images sequentially displayed on the screen and the timing input by the player. In other words, the more inputs whose timing is shifted (failed), and the greater the timing shift, the lower the score of play. For this reason, various techniques have been developed to reduce failures as much as possible and to obtain higher scores and to encourage players to improve their play and enjoy the game.

  For example, Patent Document 1 discloses a technique for changing the appearance of display such as the color and size of an instruction image in a section (bar) according to the number of failures when there is a failed input. As a result, the player can easily grasp which part of the music is likely to fail, and can correct the failure and improve the play. Patent Document 1 also discloses a technique in which a player selects a failed section (bar) and fast-forwards or skips other sections. This makes it easier for the player to play the section that he / she is not good at in the music, leading to an early improvement in play.

JP 2010-29296 A

  On the other hand, there is a demand for the player to play as much as possible without breaking the rhythm of the music that has been played so far, in order to focus on the section that the player is not good at. In other words, in order to focus on the weak sections, it is easy to get the rhythm immediately after playing only that section of the entire song or only a few surrounding sections. Conceivable.

  The present invention solves the above-described problems, and in a game in which a player performs an operation input in accordance with the reproduction of music, a game device suitable for supporting improvement of the player, a game device control method, and The purpose is to provide a program.

  In order to achieve the above object, a game device according to a first aspect of the present invention includes a reproduction unit, a display unit, a reception unit, an acquisition unit, and a determination unit.

  The playback unit plays back the music divided into a plurality of sections.

  That is, the reproduction unit reproduces music in a music game in which a player dances in accordance with the rhythm of the music, for example. Here, the music can be divided into a plurality of sections, that is, typically the bars constituting the music. Note that the section here is not necessarily limited to a section corresponding to one section, and is not limited to a section of two bars, a half of a section, or a section, and may be any section.

  The display unit displays an input instruction to be made by the player on the screen in accordance with the reproduction of the music.

For example, in a dance game in which the player dances according to the rhythm of the music, the display unit displays the choreography of the dance that the player should take on the screen. That is, a choreography is displayed on the screen, such as opening both feet to the left and right in a measure with music, and putting the left foot forward in another measure, and the player follows the displayed choreography, for example, a mat-type installed on the floor The game is advanced by pressing the buttons arranged on the front, back, left and right of the controller with the left and right feet.
As another example, in a music game in which the player plays the piano in accordance with the rhythm of the music, the display unit displays the keys of the keyboard to be played by the player on the screen. In other words, in a measure with a song, hit the keys in the order of “de”, “re”, “mi”, “fa”, and in another measure, “so”, “la”, “si”, “de”. An instruction, such as tapping the keys in the order, is displayed on the screen, and the player follows the displayed instruction, for example, by pressing a corresponding button of a controller on which a predetermined button is arranged, and advances the game.

  The reception unit receives input from the player.

  That is, the reception unit corresponds to a general controller that receives input from the player to the game device. For example, in the above example, a mat-type controller in which a button for pressing with a foot is arranged, or a controller in which a predetermined button for pressing with a hand is arranged is typical. In addition, the controller is not limited to a controller that presses a button, but is a controller that captures the movement of the player with infrared rays, or a controller that captures the motion of the controller itself being shaken or rotated by an internal acceleration sensor. There may be other various types of controllers.

  The acquisition unit acquires the degree to which the received input from the player matches the instruction displayed on the screen.

  That is, the acquisition unit receives the input information received by the reception unit and the input instruction information displayed by the display unit, and acquires how much they match. For example, in response to an instruction to press the left button of the mat type controller at a predetermined timing, the difference between the predetermined timing and the timing at which the player presses the left button is acquired. If this difference is small, the degree of matching will be high, and if the difference is large, the degree of matching will be low.

  A determination part determines whether the degree acquired in the instruction | indication matched with the area reproduced | regenerated by the reproducing part among several sections is more than a threshold value.

  That is, after the reproduction unit finishes reproducing a certain measure, the total degree of coincidence acquired by the acquisition unit is obtained for all instructions associated with the measure. If the total degree is equal to or greater than the threshold, it is determined that the player has correctly input according to the instruction. On the other hand, if the total is less than the threshold, the player cannot correctly input according to the instruction. Judge that it is.

  Here, the “threshold value” is a value serving as a reference for determining pass / fail, and may be a value set in advance in the game device, or a value that is changed and reset as described later. There may be.

  Furthermore, the playback unit replays a section (hereinafter referred to as “practice section”) that is not determined to be equal to or greater than the threshold by the determination unit.

  That is, the above-described determination unit issues a replay command to the playback unit when it is not determined that the total degree acquired for the bars that have been played back is greater than or equal to the threshold value. Then, the playback unit plays back the bar that has been played back again. As a result, the player can practice the measures whose total degree is not determined to be greater than or equal to the threshold value many times.

  With such a configuration, the section (bar) in which the player has a low degree of coincidence with the displayed instruction, that is, the section (bar) that fails to be input in accordance with the playback of the music is set as the practice section and is played back. Replayed by the part. As a result, the player can focus on the failed section, leading to an early improvement of the player.

  In the game device of the present invention, the playback unit can also start playback again from the beginning of a predetermined section before the practice section.

  When the playback section replays the practice section, that is, the section that the player has failed to input along with the playback of the music, it replayed from the previous section rather than replaying only this practice section It is assumed that the rhythm becomes easier when playing the practice section. Therefore, when the playback section replays the practice section, it replays from the beginning of the previous section by a predetermined number.

  Further, in the game device of the present invention, the playback unit plays back from the end of the practice section to the beginning of the predetermined section before the practice section in reverse order in chronological order, and further the predetermined section before the practice section. It is also possible to replay from the beginning of the section.

  That is, when the practice section is replayed by the playback section, the playback section plays back from a predetermined section before the practice section. In this case, the music is played back a predetermined number from the end of the practice section. If it suddenly returns to the beginning of the section, it is assumed that it becomes discontinuous and the music rhythm cannot be taken. In order to prevent this, playback is performed in the reverse direction from the end of the practice section to the beginning of the predetermined previous section, and then replayed from the beginning of the predetermined previous section.

  With such a configuration, when music playback returns to the previous section in time series, the player can be prepared to practice again while maintaining the tempo of the music without returning to discontinuity. it can. Also, by playing back music in reverse, a so-called disc jockey scratch play can be simulated, and the taste of the game can be enhanced.

  In the game device of the present invention, the playback unit can also replay the practice section at a lower playback speed as the number of times the practice section is replayed increases.

  That is, the difficulty level of the game is lowered by slowly reproducing the section in which the player fails to input many times and is replayed many times, and slows down the tempo. As a result, even when a novice player plays a high-level game, the player's interest can continue to be attracted without being aroused.

  Further, in the game device of the present invention, the playback unit starts playback of the music at a predetermined initial speed, replays the practice section, and then is acquired by the determination unit in the instruction associated with the practice section. If it is determined that the degree is equal to or greater than the threshold, it is possible to increase the lowered reproduction speed to a speed equal to or lower than a predetermined initial speed.

  That is, it is assumed that the practice section in which the player has failed to input has been successfully input as a result of replaying in a state where the playback speed has been reduced and played back. In this case, the playback unit then plays the music at a reduced playback speed. The method of increasing the playback speed at this time may be increased to the speed at which the music playback is started, that is, the initial speed. Alternatively, the speed may not be increased to the initial speed, but may be increased to a speed between the lowered speed and the initial speed, that is, the playback speed may be gradually increased.

  As a result, the section that the player is not good at can play again in a state where the difficulty level is lowered, and after replaying as a result of successful play in the section that is not good at the game, the difficulty level of the game is increased. Rather than playing with lowered, you can play while returning to the original difficulty.

  In the game device of the present invention, the playback unit can also play back the sections after the practice section after the lowered playback speed returns to a predetermined initial speed.

  That is, when the lowered playback speed gradually returns to the initial speed as described above, the playback of the section after the practice section does not start until the speed returns to the initial speed, and the practice section (and the section up to a predetermined number) is not started. While repeating the playback, gradually return the playback speed. With such a configuration, the player can repeat the practice of the section he is not good at while returning the lowered difficulty level step by step.

  In the game device of the present invention, the playback unit can also replay the practice section with a lower threshold value as the number of times the practice section is replayed increases.

  That is, for a section in which the player fails to input many times and is replayed many times, the determination unit reduces the threshold used for determining whether the play is successful, thereby reducing the difficulty of the game. As a result, even when a novice player plays a high-level game, the player's interest can continue to be attracted without being aroused.

  In the game device of the present invention, the playback unit starts playback of the music with a predetermined initial threshold, replays the practice section, and then obtains the instruction in the instruction associated with the practice section by the determination unit. When it is determined that the degree is equal to or higher than the lowered threshold value, the lowered threshold value can be increased to a threshold value equal to or lower than a predetermined initial threshold value.

  That is, it is assumed that the practice section in which the player has failed to input has been successfully input as a result of replaying in a state where the threshold used for determination is lowered and played by the determination unit. In this case, the playback unit then plays the music by raising the lowered threshold value. The method of raising the threshold value at this time may be raised to the threshold value when the reproduction of the music is started, that is, the initial threshold value. Alternatively, the threshold value may be increased to a threshold value between the lowered threshold value and the initial threshold value, that is, the threshold value may be gradually increased without increasing the threshold value to the initial threshold value.

  As a result, the section that the player is not good at can play again in a state where the difficulty level is lowered, and after replaying as a result of successful play in the section that is not good at the game, the difficulty level of the game is increased. Rather than playing with lowered, you can play while returning to the original difficulty.

  In the game device of the present invention, the playback unit can play back the sections after the practice section after the lowered threshold value returns to the predetermined initial threshold value.

  That is, when the lowered threshold value gradually returns to the initial threshold value as described above, the reproduction of the interval after the practice interval does not start until the threshold value returns to the initial threshold value, and the practice interval (and the interval before the predetermined interval) is not started. While repeating the reproduction, the threshold value is gradually changed. With such a configuration, the player can repeat the practice of the section he is not good at while returning the lowered difficulty level step by step.

  In order to achieve the above object, a control method for a game device according to a second aspect of the present invention is a control method executed by a game device including a reproduction unit, a display unit, a reception unit, an acquisition unit, and a determination unit. A reproduction process, a display process, a reception process, an acquisition process, and a determination process.

In the playback step, the playback unit plays back the music divided into a plurality of sections.
In the display step, the display unit displays an input instruction to be made by the player on the screen in accordance with the reproduction of the music.
In the reception process, the reception unit receives input from the player.
In the acquisition step, the acquisition unit acquires the degree to which the received input from the player matches the instruction displayed on the screen.
In the determination step, the determination unit determines whether the degree acquired in the instruction associated with the section reproduced by the reproduction unit among the plurality of sections is equal to or greater than a threshold value.
Further, in the reproduction step, the reproduction unit reproduces the section that has not been determined by the determination unit to be equal to or greater than the threshold value.

  In order to achieve the above object, a program according to a third aspect of the present invention is configured to cause a computer to function as the above game device and to cause the computer to execute each step of the above control method.

  The program of the present invention can be recorded on a computer-readable information storage medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information storage medium can be distributed and sold independently from the computer.

  According to the present invention, it is possible to provide a game device, a game device control method, and a program suitable for supporting the improvement of the player in a game in which the player performs an operation input in accordance with the reproduction of music.

  FIG. 2 is a schematic diagram of a mat-type controller, which is an example of the controller 105 used in the first embodiment. The mat-type controller 200 is arranged on the floor, and a plurality of buttons that change between a pressed state and a non-pressed state by a player's pressing operation with a foot or a hand are arranged in a predetermined area on the surface. For example, as shown in the figure, a left button 201a, a lower button 201b, an upper button 201c, a right button 201d, and the like are arranged. When these buttons are pressed by the user, an operation input corresponding to the pressed button is received.

  In the present embodiment, the mat-type controller 200 includes four buttons 201a to 201d, but the number of buttons is not limited to four, and may be three or less or five or more. Further, the operation input is not limited to the shape arranged on the floor surface, but may be a so-called touch pad shape that is held by hand or a shape held by hand.

  Moreover, it is good also as operation input of game execution by using the infrared camera etc. instead of the mat | matte-type controller 200, and capturing the motion of the whole body of a player.

  Next, a functional configuration of the game device according to the first embodiment will be described. As a typical game executed by the game device of the present invention, there is a game in which a player dances to music in a real space. Hereinafter, this embodiment will be described by taking a dance game as an example.

  FIG. 3 is a schematic diagram showing a schematic configuration according to the game device of the present invention. The game apparatus 300 of the present invention is typically realized by the upper processing apparatus 100 described above. Hereinafter, the general configuration will be described with reference to this figure.

  The game apparatus 300 includes a reproduction unit 301, a display unit 302, a reception unit 303, an acquisition unit 304, and a determination unit 305. In addition, although the function of each part is mutually related, the acceptance / rejection of each part can be changed suitably according to a use. In addition, the game apparatus 300 also includes a storage unit or the like as appropriate, and can store the current time, the content of the input performed by the player, the time of input, and the like.

  The reproduction unit 301 reproduces music divided into a plurality of sections. That is, for example, after the audio data of the music recorded on the DVD-ROM is read by the DVD-ROM drive 107 and temporarily stored in the RAM 103 or the like, the audio of the music is output to the speaker by the function of the audio processing unit 109. Let That is, the audio processing unit 109 and the like function as such a reproduction unit 301.

  Here, the plurality of sections correspond to, for example, bars constituting the music. That is, a music piece is divided into the number of bars constituting it. A bar is composed of a plurality of beats such as two beats, three beats, four beats, etc., and a music piece is generally composed of a number of such beats, that is, bars.

  The display unit 302 displays an input instruction to be made by the player on the screen in accordance with the reproduction of the music. That is, for example, the image data associated with the music being played back by the playback unit 301 is read from the DVD-ROM and displayed on the monitor by the image processing unit 108. That is, the image processing unit 108 or the like functions as such a display unit 302.

  Here, the display unit 302 is interlocked with the playback unit 301. For example, when the playback unit 301 is playing back the nth bar, the display unit 302 monitors an input instruction to be made by the player corresponding to the nth bar. To display. For example, in a dance game, a player can perform an action or choreography in accordance with the rhythm of a music piece by inputting according to such an instruction.

  The accepting unit 303 accepts input from the player. The controller 105 connected via the interface 104, that is, the mat-type controller 200 as an example, functions as such a reception unit 303.

  In accordance with the instruction displayed on the display unit 302, the player performs input to the receiving unit 303 of the mat type controller 200, for example. That is, an input is made to the game apparatus 300 by pressing the left button 201a or the right button 201d of the mat type controller 200 or pressing the lower button 201b or the upper button 201c.

  The acquisition unit 304 acquires the degree to which the accepted input from the player matches the instruction displayed on the screen. The CPU 101 functions as such an acquisition unit 304 in conjunction with the RAM 103.

  That is, the acquisition unit 304 receives the input information received by the reception unit 303 and the input instruction information displayed by the display unit 302, and acquires the degree to which they match. For example, in response to an instruction to press the left button 201a of the mat type controller 200 at a predetermined timing, the difference between the predetermined timing and the timing at which the player presses the left button 201a is acquired. If this difference is small, the degree of matching will be high, and if the difference is large, the degree of matching will be low.

  The determination unit 305 determines whether or not the degree acquired in the instruction associated with the section reproduced by the reproduction unit 301 among the plurality of sections is equal to or greater than a threshold value. The CPU 101 functions as such an acquisition unit 304 in conjunction with the RAM 103.

  That is, after the reproduction unit 301 finishes reproducing a certain measure, the total degree of coincidence acquired by the acquisition unit 304 is obtained for all instructions associated with the measure. If the total degree is equal to or greater than the threshold, it is determined that the player has correctly input according to the instruction. On the other hand, if the total is less than the threshold, the player cannot correctly input according to the instruction. Judge that it is.

  Furthermore, the playback unit 301 replays a section (practice section) that has not been determined by the determination unit 305 to be equal to or greater than the threshold value. That is, the determination unit 305 issues a replay command to the playback unit 301 when the total degree obtained for the bars that have been played back is not greater than or equal to the threshold, Play again.

  FIG. 4 is a diagram showing a configuration example of a game screen according to the game apparatus 300 of the present invention. The display unit 302 typically displays a game screen 400 as shown in the figure on the monitor by the image display unit 108 of the information processing apparatus 100.

  In this game screen 400, a plurality of types of instruction images 401a to 401d are synchronized with the rhythm of the music to be played and the like along the movement lanes 402a to 402d (lanes corresponding to the type of the instruction image 401) from below. It shows how they appear sequentially, move to information, and disappear.

The instruction images 401a to 401d represent arrow symbols in different directions, and correspond to an operation of pressing (stepping on) the buttons 201a to 201d of the mat-type controller 200 described above. That is,
(A) An instruction image 401a, which is a left-pointing arrow symbol, instructs the player to step on the left button 201a of the mat-type controller 200.
(B) The instruction image 401b, which is a downward arrow symbol, instructs the player to step on the down button 201b of the mat-type controller 200.
(C) The instruction image 401c, which is an upward arrow symbol, instructs the player to step on the mat controller 200's upper button 201c.
(D) The instruction image 401d, which is a right-pointing arrow symbol, instructs the player to step on the right button 201d of the mat-type controller 200.

  These instruction images 401a to 401d appear from the lower ends (starting points) of the moving lanes 402a to 402d, move upward in the moving lanes 402a to 402d, and disappear at the upper ends (end points) of the moving lanes 402a to 402d. . Then, at the timing when any one of the instruction images 401a to 401d reaches the reference image 403a to 403d (an object having the same shape as each of the instruction images 401a to 401d is fixed), the instruction image is displayed to the player. Operations corresponding to 401a to 401d are required.

In other words, when the instruction images 401a to 401d are exactly overlapped with the reference images 403a to 403d, an operation of pressing (stepping on) the buttons 201a to 201d of the mat type controller 200 indicated by the instruction images 401a to 401d is obtained. It has been. For example,
(A) At the timing when the instruction image 401a moves to the reference image 403a (more specifically, when the instruction image 401a and the reference image 403a overlap exactly), the player steps on the left button 201a of the mat type controller 200. It has been demanded. Similarly,
(B) At the timing when the instruction image 401b moves to the reference image 403b, the player is required to step on the lower button 201b of the mat type controller 200,
(C) At the timing when the instruction image 401c moves to the reference image 403c, the player is required to step on the upper button 201c of the mat type controller 200,
(D) At the timing when the instruction image 401d moves to the reference image 403d, the player is required to step on the right button 201d of the mat type controller 200.

4 shows the case where the instruction images 401a to 401d move from the lower side to the upper side of the game screen 400, the movement direction of the instruction images 401a to 401d is not limited to this and is arbitrary. For example, the game screen 400 may be moved from the upper side to the lower side, or may be moved in the horizontal direction (from the right side to the left side of the game screen 400 or from the left side to the right side of the game screen 400). Further, instead of the reference images 403a to 403d, a reference line orthogonal to the moving lanes 402a to 402d may be displayed and used as a reference for timing when the player moves. Further, the movement lanes 402 a to 402 d may be hidden on the game screen 400.
Furthermore, the shape of the instruction images 401a to 401d is an example, and may be other shapes. In addition, an operation direction (instruction direction) instructed to the player is also an example, and may be another operation direction.

  As described above, in the present embodiment, the button instructed by the mat type controller 200 at the timing when the instruction images 401a to 401d that scroll and move on the movement lanes 402a to 402d in the game screen 400 overlap the reference images 403a to 403d. By stepping on 201a to 201d with a foot, the game can be advanced while dancing along with the music to be played.

  Here, the music reproduced by the reproducing unit 301 is divided into a plurality of sections. In the present embodiment, the bars constituting the music are taken as a plurality of sections, and the bars are composed of four beats. In FIG. 4, the plurality of instruction images 401 a to 401 d that are scrolled are divided into three bars 404 a to 404 c in the game screen 400 (portion surrounded by a one-dot chain line). Here, one bar 404a to 404c is composed of four beats, and one instruction image 401a to 401d is associated with one beat, and as a result, one bar 404a to 404c has four instruction images 401a. To 401d.

Specifically, in measure 404a, the player
(1) Since the instruction image 401a instructing “left” is shown at the first beat, an operation of stepping on the left button 201a of the mat type controller 200 is performed.
(2) Since the instruction image 401c instructing “up” is shown in the second beat, an operation of stepping on the upper button 201c of the mat type controller 200 is performed.
(3) Since the instruction image 401d indicating “right” is shown at the third beat, an operation of stepping on the right button 201d of the mat type controller 200 is performed.
(4) Since the instruction image 401b instructing “down” is shown at the fourth beat, an operation of stepping on the lower button 201b of the mat type controller 200 is performed.
Furthermore, in the next measure 404b, the player
(5) Since the instruction image 401a instructing “left” is shown at the first beat, an operation of stepping on the left button 201a of the mat type controller 200 is performed.
(6) Since the instruction image 401b instructing “down” is shown at the second beat, an operation of stepping on the lower button 201b of the mat type controller 200 is performed.
(7) Since the instruction image 401d indicating “right” is shown at the third beat, an operation of stepping on the right button 201d of the mat type controller 200 is performed.
(8) Since an instruction image 401c indicating “up” is shown at the fourth beat, an operation of stepping on the upper button 201c of the mat type controller 200 is performed.
In FIG. 4, only the next bar 404 c has only two direction images 401 b and 401 d and appears to have a short length. This is because only part of the bar 404 c is displayed in the game screen 400. Yes, the lengths of the three bars 404a to 404c are all the same.

  Here, in FIG. 4, one bar 404 is composed of four beats, but in this embodiment, the number of beats constituting one bar 404 is not limited to four, and even if it is composed of two beats, it is composed of eight beats. Or it may consist of a different number of beats. In FIG. 4, one instruction image 401 always corresponds to one beat. However, the present embodiment is not limited to this, and a plurality of instruction images 401 (for example, left) are included in one beat. The instruction image 401a indicating the direction and the instruction 401c indicating the upward direction may be associated with each other at the same time), or any instruction image 401 may be associated. There may be no beats.

  In the present embodiment, the acquisition unit 304 determines whether or not the buttons 201a to 201d in the directions indicated by the instruction images 401a to 401d are pressed at a timing when the instruction images 401a to 401d overlap the reference images 403a to 403d. Get the degree of matching. That is, the difference between the time when the buttons 201a to 201d are pressed from the player and the time when the instruction is given (the instruction image 401 and the reference image 403 overlap) is acquired, and the smaller the difference is, the higher the degree of matching is. Assume that the greater the difference, the lower the degree of matching.

For example, assume that the following points are given to the above difference.
(A) If it is 0 to 0.03 seconds, 5 points (hereinafter referred to as “PERFECT”),
(B) If 0.03 to 0.06 seconds, 3 points (hereinafter referred to as “GREAT”),
(C) 1 point (hereinafter referred to as “GOOD”) if 0.06 to 0.1 seconds,
(D) 0 point if it exceeds 0.1 seconds (hereinafter referred to as “BAD”),
At this time, the acquisition unit 304 assigns such points as many as the number of input instructions in the music. When the sum of such scores is taken as a score for the entire music and displayed as a score, it becomes an index of how much the player can press the button 201a to 201d in the designated direction at the designated timing.

  If the player can focus on the low score portion of the entire music with respect to the score acquired in this way, the score for the entire music can be increased and the progress of the game can be accelerated. Therefore, in the present embodiment, the determination unit 305 sets a threshold value set in advance for each measure 404, and determines whether the total number of points acquired for the input instruction in the measure 404 is equal to or greater than the threshold value. To do. Then, the playback unit 301 replays the measure 404 that has not been determined by the determination unit 305 to be equal to or greater than the threshold.

Specifically, let us consider a case where 10 points are associated as threshold values with respect to the total score for each measure 404. In the example of FIG. 4, four instruction images 401 a to 401 d are associated with the measure 404 a, so that the total number of points acquired based on the input timing of the player with respect to the four instruction images 401 a to 401 d is 10 If the score is greater than or equal to the score, the measure 404a is determined to be acceptable, and if the score is less than 10, it is determined to be unacceptable.
For example, the difference between the timing input from the player for the four instruction images 401a to 401d and the specified timing (the instruction image 401 overlaps the reference image 403)
(A) In the case of “PERFECT”, “PERFECT”, “GREAT”, and “GREAT”, the total score is 5 points + 5 points + 3 points + 3 points = 16 points, which is a pass. As a result, the process proceeds to playback of the next measure 404b.
(B) In the case of “GREAT”, “GOOD”, “GOOD”, and “BAD”, the total number of points is 3 points + 1 point + 1 point + 0 point = 5 points, which is rejected. As a result, this measure 404a is reproduced again without shifting to the reproduction of the next measure 404b.

Here, in order to compare with the threshold value, the determination unit 305 does not have to take a simple sum (sum) of the degree of matching of the inputs to the individual instruction images 401. That is, for example, the degree of coincidence of the first beat is regarded as important, and each degree of coincidence may be weighted and summed and compared with a threshold value.
Alternatively, a criterion may be used in which, even if there is at least one “BAD” in the measure 404, the sum of the degrees of coincidence is not taken and a failure is given. In this case, the threshold value used for the determination is 3 points (“GOOD”) in the above example, and the determination unit 305 checks the degree of matching of the input with respect to the individual instruction images 401 in the measure 404 and can determine even one. Anything less than 3 points (ie “BAD”) will be rejected.

  Thus, by determining pass / fail for each measure 404 and replaying the measure 404 that has not reached the standard, the player can repeatedly focus on the measure 404 that he / she is not good at.

  In the present embodiment, the playback unit 301 plays back again from the beginning of a section (measure 404) that is not determined to be equal to or greater than the threshold by the determination unit 305, that is, a predetermined section before the practice section. For example, let us consider a case where playback is started again from the beginning of the previous measure 404. If the game is progressing as displayed on the game screen 400 in FIG. 4, for example, if the player cannot play well in the measure 404b and is determined to be unacceptable by the determination unit 305, then the music is one before. Will be reproduced again from the beginning of the bar 404a. Here, in the present embodiment, the bars 404 to be replayed are not limited to the previous bars 404 from the failed bars 404, but from the bars 404 that are two or three before or more than that. You may start.

  With such a configuration, when a measure 404 that has been rejected by the determination unit 305 is replayed by the playback unit 301, playback is started from a few previous measures 404 rather than replaying only the failed measure 404. By re-doing, it is assumed that the player can easily take a rhythm when playing the failed measure 404.

  Further, in the present embodiment, the playback unit 301 has a section (bar 404) that is not determined to be equal to or greater than the threshold by the determination unit 305, that is, from the end of the practice section to the beginning of a predetermined section before the practice section. Are reproduced in reverse order in chronological order, and are reproduced again from the beginning of a predetermined section before the practice section. In other words, when replaying from the beginning of the previous measure 404 to the measure 404 that has been determined to be unacceptable by the determination unit 305 as described above, it is not possible to suddenly discontinuously return to the beginning of the previous measure 404. Instead, play the song backwards and return.

  FIG. 5 is a diagram showing a configuration example of the game screen 400 when the music is being played back in reverse. The components in this figure are basically the same as those of the game screen 400 shown in FIG. 4, but in FIG. 4, the instruction images 401 a to 401 d show the corresponding movement lanes 402 a to 402 d below the game screen 400. The instruction images 401a to 401d in FIG. 5 are scrolled from top to bottom.

  That is, in FIG. 4 in which the music is played back by the playback unit 301 in the normal time-series order, the display unit 302 displays the instruction images 401a to 401d in the game screen 400 in the forward direction (downward) as the playback unit 301 plays back. In FIG. 5 in which music is reproduced in the reverse direction in time series by the reproduction unit 301, the display unit 302 displays the instruction images 401 a to 401 d in the reverse direction in accordance with the reproduction of the reproduction unit 301. Scroll to (from top to bottom).

The music played in the reverse direction at this time is not usually music accompanied by a rhythm or melody. Therefore, during reverse playback, the player dances or plays an instrument along with the playback. Becomes difficult. However, the player can be prepared to practice again while maintaining the tempo of the music, rather than discontinuously shifting the music playback to the previous measure 404 in time series as described above. is assumed.
Furthermore, playing a music piece in reverse is also seen in so-called disc jockey scratch play, which can lead to an increase in the taste for enjoying a music game.

  FIG. 6 is a diagram showing an example of the relationship between the elapsed time and the measure of the music to be played back in the present embodiment. Based on the configuration described so far in the present embodiment, the order in which the bars constituting the music are played will be described below with reference to the graph of FIG.

  In the graph of FIG. 6, the horizontal axis represents elapsed time, and the vertical axis represents music bars to be played. Here, the origin of the graph corresponds to the time when the music starts to be played back, and the bars of the music that are played back as time elapses are the first bar, the second bar, the third bar, and so on, Move to the area. That is, as long as the music is played normally without replaying, the graph is drawn linearly from the origin to the upper right.

  Here, let us consider a case where the player cannot input properly in the i-th measure of the music. That is, the determination unit 305 did not determine that the degree of coincidence between the input received by the receiving unit 303 in the i-th measure and the input instruction displayed on the display unit 302 is greater than or equal to a preset threshold value. Corresponds to the case. In this case, reverse playback of the music is started by the playback unit 301 when playback of the music has progressed to the end of the i-th measure, that is, when input has failed 601a in FIG.

The reverse reproduction here is performed until the beginning of a predetermined predetermined number of bars. Here, for the sake of explanation, it is assumed that reverse playback is performed from the i-th measure that has failed to be input to the previous i-th measure. On the graph of FIG. 6, the graph moves in the lower right direction from the input failure time 601 a to the reverse playback end time 602 a. Then, at the end of reverse playback 602a, playback starts in the forward direction again in the order of the i-1th bar and the i-th bar.
Here, in the present embodiment, the number of bars returned from the i-th bar in which the player has failed to input is not limited to one. You may return to a predetermined n-th previous bar. For example, when returning to the previous two, playback is performed in the reverse direction from the end of the i-th bar to the beginning of the i-th bar, and then starts to be played in the forward direction again from the start of the i-th bar.

  FIG. 6 further shows a case where the player cannot input properly again in the i-th measure (when input fails 601b). At this time, in this embodiment, the music is reversely played back to the previous bar again in chronological order, and then played again from there. That is, the music is played in the reverse direction from the input failure time 601b that is the last of the i-th measure that failed the second time to the reverse playback end time 602b that is the first time of the i-1th measure. Again, playback starts in the forward direction from the end of reverse playback 602b.

  As described above, in this embodiment, as long as the player keeps failing to input, the same measure is reproduced again and again, and the measure that the player is not good at can be practiced over and over again.

  In FIG. 6, after that, playback starts again from the i-1th bar, and the player succeeds in inputting the ith bar at the third time (when the input is successful 603a), and further, the i + 1th bar and the i + 2th bar are called. Play forward in order. That is, on the graph of FIG. 6, the process proceeds from the reverse playback end 602b to the upper right direction, passes through the input success time 603a, and continues to be played in the upper right direction, that is, the music is played in the forward direction.

  Next, it is assumed that the input fails at the j-th measure (j> i), and the determination unit 305 does not determine that the degree of matching is greater than or equal to the threshold (when input fails 601c). At this time, similarly to the processing in the i-th measure, the music piece is reversely reproduced from the end of the j-th measure that has failed to be input to the beginning of the previous j-1th measure. On the graph of FIG. 6, the process proceeds from the input failure time 601c to the reverse playback end time 602c. Thereafter, the music is reproduced in the forward direction from the beginning of the j-1th bar again. If the input of the jth bar is successful (when the input is successful 603b), the music is played in the order of the j + 1th bar and the j + 2th bar. Therefore, the player can try again at the j-th measure whose input has failed.

  With such a configuration, the game device 300 according to the present embodiment continuously reproduces the failed measure every time the player fails to input. At that time, since it starts playing backward after returning to the beginning of the previous measure in chronological order from the failed measure, the rhythm is checked from the front of the failed measure while maintaining the tempo of the song. However, you can focus on the failed bars.

  FIG. 7 is a flowchart showing a flow of processing according to the game device 300 of Embodiment 1 of the present invention. The processing flow realized in the game apparatus 300 in the present embodiment that has been described so far will be summarized below.

  First, the CPU 101 of the game apparatus 300 performs various initial settings (step S101). Here, the selection of the music to be played by the player, the acquisition of the tempo of the music, the instruction image 401 associated with the music, the reference image 403, and the reading of the data recording the movement lane 402 associated with the instruction image 401 are read. Other various images arranged on the game screen 400 are read.

  Next, the CPU 101 of the game apparatus 300 issues an instruction to the sound processing unit 109, that is, the playback unit 301 to play the music selected by the initial setting (step S102). Music data can be prepared as various audio data such as MIDI (Musical Instrument Digital Interface) data, PCM (Pulse Coded Modulation) data, MP3 (MPEG Audio Layer-3) data and Ogg Vorbis data. These data are stored in a ROM medium attached to the DVD-ROM drive 107.

  From here, the flowchart of FIG. 7 will be described focusing on which bars of the music the playback unit 301 is playing. That is, a variable n (n is a natural number) for indicating the first measure is provided and n is appropriately updated to indicate which measure of the music piece is being reproduced. Here, although not particularly specified in the flowchart, the display unit 302 performs a process of displaying the game screen 400 on the monitor by the image display unit 108 at every predetermined vertical synchronization period. In other words, the game screen 400 including the instruction image 401 that scrolls on the moving lane 402 is displayed on the monitor each time the music is being reproduced by the reproducing unit 301.

  When the music performance is started in step S102, first, 1 is substituted into the set variable n (step S103). Then, the playback unit 301 starts playback of the n-th measure, that is, the first measure here (step S104).

  When the reproduction of a measure is started in this way, the game device 300 of the present embodiment acquires the degree of coincidence between the input instruction associated with the measure and the input from the player (step S105). ). That is, the degree to which the reception unit 303 receives an input from the player, and the received input matches the input timing displayed on the display unit 302 (the timing at which the instruction image 401 overlaps the reference image 403). Is acquired by the acquisition unit 304. Usually, a high score is obtained when the degree of matching is high (for example, “PERFECT” described above), and a low score is obtained when the degree of matching is low (for example, “BAD” described above).

  Then, it is determined whether or not the reproduction of the n-th measure, that is, the first measure in this case, which is the currently-played measure is finished (step S106). If not completed (step S106; NO), the process returns to step S105. That is, the degree of coincidence in step S105 is obtained every time there is an input from the player or every time there is an input instruction until the reproduction within the measure is finished.

  On the other hand, when the reproduction of the currently playing measure is completed (step S106; YES), the game apparatus 300 according to the present embodiment is next in the first measure because the nth measure, that is, n = 1 here. Is determined to be successful (step S107). That is, it is determined whether the acquired degree is equal to or greater than a preset threshold value. Specifically, the determination unit 305 obtains, for example, the total of the measures for which the playback has ended, from the degree of matching (the score obtained from the number) obtained in step S105, for example, It is determined whether it is equal to or greater than a predetermined threshold. The method of comparison with the threshold value here is not limited to comparison with the sum of the degree of matching obtained within the measure, and as described above, even one degree of matching within the measure is not “BAD”. It is good also as a standard of whether it is more than a threshold value.

  Here, when it is determined that the play in the measure is successful (step S107; YES), that is, in the measure where the playback is finished (here, the first measure), the player can input appropriately according to the instruction. The game apparatus 300 according to the present embodiment reproduces the next measure. That is, for example, if the first measure has been played up to now, the music is played in the normal order, such as shifting to the playback of the second measure.

  Therefore, here, it is determined whether or not the n-th measure that is currently reproduced is the last measure (step S108). If it is not the last measure (step S108; NO), n + 1 is substituted for the value of n (step S109), that is, n is incremented, and the process returns to step S104 to start reproduction of the next measure. That is, for example, if the number of bars constituting the music being played is 100 and the reproduced bars are the first bar to the 99th bar, the determination in step S108 is NO, and the next bar is determined. Transition to playback. For example, when the reproduction of the first measure has been completed, the reproduction of the next second measure is started.

  As described above, the processes from step S104 to S109 are repeated, and as long as it is determined as YES in step S107, the last bar is reached from the first bar in the chronological order of the second bar, the third bar. It will continue to play music. In other words, as long as the player can properly input the bars being played according to the instructions, the music is normally played from the beginning to the end.

  On the other hand, if it is determined in step S107 that the play within the measure has failed (step S107; NO), that is, if the player cannot input properly according to the instruction, the flowchart of FIG. The process proceeds to playback.

  Here, when the measure for which the degree of coincidence is not determined to be greater than or equal to the threshold is the n-th measure, the game device 300 of the present embodiment reversely reproduces this n-th measure (step S110). That is, since the time point determined by the determination unit 305 is immediately after the end of the reproduction of the n-th measure, the reproduction is performed in the reverse direction from the position where the reproduction ends.

  Then, it is determined whether or not the reproduction has been returned to the beginning of a predetermined predetermined number of bars by reverse reproduction (step S111). That is, when reverse playback is started from the end of the nth bar as described above, for example, if it is determined that reverse playback is performed up to the previous bar, the reverse playback is performed up to the beginning of the n-1st bar. For example, if it is determined that reverse playback is performed up to ten bars before, it is determined whether reverse playback is performed up to the beginning of the n-10th bar.

  Here, when it is determined that it has not returned to the beginning of the predetermined number of measures (step S111; NO), n-1 is substituted for the value of n (step S112), that is, n is decremented, and the step is again performed. Returning to S110, reverse playback is performed. That is, the previous bar is reproduced in reverse order in time series. In this way, until the beginning of the predetermined number of bars to be returned is reached, the previous bar continues to be reversely played one by one in chronological order one by one, the nth bar, the n-1th bar, and the n-2th bar. Become.

  When the game apparatus 300 returns to the beginning of the predetermined number of bars (step S111; YES), the game apparatus 300 according to the present embodiment ends the reverse reproduction and returns to step S104. That is, reverse playback is performed from the end of a measure that the player has not been able to input properly to the beginning of a predetermined number of bars, and playback is started in the normal time-series direction from the start of the predetermined number of bars. For example, when the measure that the player could not input properly is the n-th measure as described above, and it is determined that the previous measure is played back to the previous measure, the measure that is one measure before the end of the n-th measure is displayed. Reverse playback is performed up to the beginning of the (n-1) th bar, and playback is started again from the beginning of the (n-1) th bar. In this manner, the player can input appropriately according to the instruction, and is returned to the predetermined measure until it is determined that the degree of coincidence is equal to or greater than the threshold, and reproduction is continued.

  Thereafter, when it is determined that the degree of coincidence is greater than or equal to the threshold for all the bars constituting the music and the last bar has been played back (step S108; YES), the music playback is terminated and the present process is performed. finish.

  In the present embodiment, when the player fails to input in the nth bar, reverse playback is performed from the nth bar to a predetermined bar. For example, if the predetermined number is one here, the reverse reproduction is performed up to the beginning of the n-1th bar. And it reproduces in order of the (n-1) -th measure and the n-th measure, and a player plays a game with respect to each measure. At this time, the measure for which the player has failed is the n-th measure, and the (n−1) -th measure is a measure that should have already been successful. Therefore, the determination unit 305 does not have to determine the n−1-th measure. That is, in step S107, it is assumed that the process for determining whether or not the play in the measure has succeeded is performed only for the nth measure that the player has failed. You may decide not to process. By doing so, since the player is played from the previous (n-1) th bar, the player can concentrate on the failed nth bar play while taking the tempo in advance, and can easily practice the weak bars. It is assumed that

  With such a configuration, the game device 300 according to the present embodiment continuously reproduces the failed measure every time the player fails to input. At that time, since it starts playing backward after returning to the beginning of the previous measure in chronological order from the failed measure, the rhythm is checked from the front of the failed measure while maintaining the tempo of the song. However, you can focus on the failed bars. As a result, early improvement in play can be supported.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. In the first embodiment, the section in which the player has failed to input is replayed at the same tempo as when it was first played, and the threshold used as a criterion for pass / fail by the determination unit 305 is also the first time played back. Replayed using the same threshold. In the present embodiment, as the section in which the player has failed to input is replayed, the section is replayed at a slower playback speed, and the threshold value that is a criterion for pass / fail becomes lower.

  FIG. 8 is a diagram showing how the playback speed and the threshold value change in the present embodiment. Hereinafter, with reference to this figure, how the playback speed and the threshold value used for determination change when the player cannot input according to the instruction and is determined to be unacceptable by the determination unit 305. Will be explained.

  First, FIG. 8A is a diagram showing an example of the relationship between the elapsed time, the measure of the music to be played back, and the playback speed. In the graph of this figure, like the graph of FIG. 6, the elapsed time is taken on the horizontal axis, and the measure of the music to be reproduced is taken on the vertical axis. That is, the beginning of the music corresponds to the origin of the graph, and the graph is drawn linearly from the origin in the upper right direction as long as the music is played normally without replaying. At this time, in this embodiment, it is assumed that reproduction is performed at a predetermined first reproduction speed 801a.

  Here, as in FIG. 6, let us consider a case where the player cannot input properly at the i-th measure of the music. That is, this corresponds to the case where the determination unit 305 does not determine that the degree of matching between the input received by the receiving unit 303 in the i-th measure and the input instruction displayed on the display unit 302 is equal to or greater than the threshold value. . In this case, reverse playback of the music is started by the playback unit 301 at the time when the playback of the music has progressed to the end of the i-th measure, that is, when the input has progressed to 601a at the time of input failure in FIG.

Here, similarly to FIG. 6, it is assumed that the reverse reproduction is performed from the i-th measure that has failed to be input to the previous i-1th measure. On the graph of FIG. 8A, the graph moves in the lower right direction from the input failure time 601a to the reverse playback end time 602a. In the present embodiment, the reproduction speed at this time remains the predetermined first reproduction speed 801a and does not change.
Then, at the end of reverse playback 602a, playback starts in the forward direction again in the order of the i-1th bar and the i-th bar. In the present embodiment, the playback speed at this time also remains the predetermined first playback speed 801a and does not change.

FIG. 8A shows a case where the player cannot input properly again in the i-th measure (input failure time 601b). At this time, as in FIG. 6, the music is played in the reverse direction from the input failure time 601b at the end of the i-th measure that failed the second time to the end of reverse playback 602b at the beginning of the i-1th measure again. Is done. In this embodiment, the playback speed at this time is lowered to a predetermined second playback speed 801b.
Then, the music starts to be played in the forward direction from the end of reverse playback 602b. In the present embodiment, playback is performed at the second playback speed 801b at this time. That is, playback starts in the forward direction at the same speed as the playback speed reversely played until the end of reverse playback 602b.

Further, FIG. 8A shows a case where the player cannot input properly at the i-th measure three times (input failure 601c). Also at this time, the music is played in the reverse direction from the input failure time 601c which is the last of the i-th measure failed at the third time to the end of reverse playback 602c which is the first time of the i-1th measure. The reproduction speed at is further reduced to a predetermined third reproduction speed 801c.
Then, the music starts to be played in the forward direction from the end of reverse playback 602c while maintaining the third playback speed 801c. Then, when the input of the i-th measure is successful in the fourth try (when input is successful 603a), the music is reproduced in the forward direction in the order of the i + 1-th measure and the i + 2-th measure at the third playback speed 801c. To go. That is, on the graph of FIG. 8A, the process proceeds from the end of reverse playback 602c in the upper right direction, passes through the input success time 603a, and continues to be played in the upper right direction, that is, the music is played in the forward direction.

  As described above, in this embodiment, the measure for which the player has failed to input is replayed at a slower playback speed as the bar is replayed. In other words, in the present embodiment, the playback unit 301 plays a section that has not been determined to be equal to or greater than the threshold by the determination unit 305, that is, a practice section at a lower playback speed as the number of times the section is played back again. Try again. As a result, the difficulty level of the game can be lowered, and even when a novice player plays a high-level game, the player's interest can continue to be attracted without being aroused.

  Furthermore, in the present embodiment, the difficulty level of the game may be adjusted by lowering the threshold used by the determination unit 305 to determine success or failure of the play as well as lowering the playback speed. That is, in the present embodiment, the playback unit 301 sets the threshold as the first threshold as the number of times that the section that has not been determined to be equal to or greater than the threshold by the determination unit 305, that is, the practice section, is replayed. Lower and restart playback.

  FIG. 8B is a diagram illustrating an example of the relationship between the elapsed time and the threshold value used for determination in the present embodiment. Also in the graph of this drawing, the elapsed time is taken on the horizontal axis, and the horizontal axis is shared with the graph of FIG. On the other hand, the vertical axis is a threshold value, and the higher the threshold value, the lower the lower threshold value.

In the present embodiment, the threshold used for the determination unit 305 is the predetermined first threshold 802a until the player fails to input twice in the same measure. That is, in FIG. 8A, in the elapsed time until the player fails the second time in the i-th measure (input failure time 601b), the threshold is the first threshold as shown in FIG. 8B. It remains unchanged at 802a.
On the other hand, after the second failure, the threshold value is lowered to the second threshold value 802b. That is, in the elapsed time corresponding to the input failure time 601b on the graph of FIG. 8A, the threshold value in FIG. 8B is lowered from the predetermined first threshold value 802a to the second threshold value 802b. Yes. Therefore, when the player plays the i-th measure for the third time, the player can play with a lower threshold used for success / failure determination.
Furthermore, if it fails for the third time, it is lowered to the third threshold value 802c. That is, in the elapsed time corresponding to the input failure time 601c on the graph of FIG. 8A, the threshold value in FIG. 8B is lowered from the predetermined second threshold value 802b to the third threshold value 802c. Yes. Therefore, when the player plays the i-th measure for the fourth time, the player can play with the threshold value used for success / failure determination further lowered.

  As described above, in the present embodiment, the measure for which the player has failed to input is replayed with a lower threshold used for determination as it is replayed. As a result, the difficulty level of the game can be lowered, and even when a novice player plays a high-level game, the player's interest can continue to be attracted without being aroused.

  FIG. 9 is a flowchart showing a flow of processing according to the game apparatus 300 of the present embodiment. This figure is basically the same as the flowchart described in FIG. 7 in the first embodiment, but the process of lowering the playback speed and threshold (the part surrounded by the dotted line in FIG. 9) is performed in steps S107 and S110. Newly added.

  That is, when the game process is started, the game apparatus 300 according to the present embodiment first performs various initial settings (step S101) and starts playing the music (step S102). Then, the playback unit 301 provides a variable n (n is a natural number) for indicating the number of measures, and first substitutes 1 for the value of the variable n (step S103).

  From here, every time the value of the variable n is increased in order, the music is reproduced in chronological order, such as the first measure, the second measure, and the third measure. That is, as long as it is determined as YES in step S107, as in the first embodiment, the music is played to the end in the normal order, and the degree of whether the input made by the player for each measure matches the predetermined instruction is determined. Acquisition is performed (steps S104 to S109).

  Here, in this embodiment, when it is determined NO in step S107, that is, when it is determined that the player's play is unsuccessful, for example, in the n-th measure, processing different from that of the first embodiment is entered.

  In the present embodiment, it is determined whether or not play has failed in the n-th measure (step S201). When it is determined that it is not the first time (step S201; NO), the playback speed at which the playback unit 301 plays the music is decreased (step S202), and the threshold used by the determination unit 305 for the determination in step S107 is further decreased (step S203). . On the other hand, when it is determined that it is the first time (step S201; YES), neither the playback speed nor the threshold value is changed, that is, nothing is done here. Thereafter, as in the first embodiment, the process is reversely reproduced from the nth bar to the beginning of the predetermined bar (steps S110 to S112), and the process returns to step S104.

  If the playback speed and the threshold value are lowered, then the game is played based on the lowered playback speed and threshold value. That is, the player plays with the music that is played back at the lowered playback speed. In step S107, based on the threshold value lowered by the determination unit 305, it is determined whether play within each measure is successful.

  That is, the playback speed and threshold value are not lowered for the measure for which the player has failed to input for the first time, and the playback speed and threshold value are lowered when play in the same measure fails twice. Furthermore, the playback speed and the threshold value are lowered each time the play in the same measure fails every time the third and fourth times fail. In other words, failing many times means that the bar is not good for the player, so the difficulty is gradually lowered to make it easier to succeed.

  Here, in the flowchart of FIG. 9, the playback speed and the threshold are not lowered for the first failed measure. This is based on the assumption that if the difficulty level is lowered just after a single failure, the difficulty level is frequently reduced too much, and the present embodiment is not limited to this. In other words, the playback speed and threshold may be lowered for the first failed measure, or the playback speed and threshold are not lowered only by failing the same measure twice. You may make it lower. In the former case, the difficulty level is frequently decreased, and in the latter case, the number of times the difficulty level is decreased is decreased. It is possible to adjust the difficulty level change in such a balance.

  In this embodiment as well, as in the first embodiment, the player fails to input at the nth bar and, for example, the reverse playback is performed up to the beginning of the n−1th bar, and then the n−1th bar and the nth bar. When played back in order, the determination unit 305 does not have to determine the n−1th bar. That is, in step S107, it is assumed that the process for determining whether or not the play in the measure has succeeded is performed only for the nth measure that the player has failed. You may decide not to process. By doing so, it is assumed that the player can concentrate on the play of the failed n-th measure, and can easily practice a measure that is not good at it.

  In addition, here, it has been described that the section in which the player has failed to input is replayed at a slower playback speed as it is replayed, and at the same time, the threshold value for pass / fail criteria becomes lower. However, in the present embodiment, the reproduction speed and the threshold value are not limited to be lowered at the same time. In other words, the difficulty level of the game may be adjusted by lowering the playback speed without lowering the threshold value, or the difficulty level of the game may be adjusted by lowering the threshold value without lowering the playback speed.

  With such a configuration, in this embodiment, the section in which the player has failed to input is replayed at a slower playback speed and the threshold value is lower as the section is replayed.

  As a result, even when a novice player plays a high-level game, it is possible to prevent the situation where the difficulty is too high to advance to the previous section of the music, and the player is excited. You can keep pulling.

(Embodiment 3)
Next, a third embodiment of the present invention will be described. In the second embodiment, the playback speed and threshold value once lowered are not restored. In the present embodiment, if the player can appropriately input according to the instruction in the section where the playback speed and the threshold are lowered and replayed, the lowered playback speed and threshold are restored.

  FIG. 10 is a diagram showing how the playback speed and the threshold value change in the present embodiment. Hereinafter, with reference to this figure, how the playback speed and the threshold value used for determination change when the player cannot input according to the instruction and is determined to be unacceptable by the determination unit 305. Will be explained.

  First, FIG. 10A is a diagram showing an example of the relationship between the elapsed time, the measure of the music to be played back, and the playback speed. In the graph of this figure, like the graphs of FIGS. 6 and 8A, the elapsed time is taken on the horizontal axis, and the measure of the music to be played is taken on the vertical axis. That is, the beginning of the music corresponds to the origin of the graph, and the graph is drawn linearly from the origin in the upper right direction as long as the music is played normally without replaying. At this time, in this embodiment, it is assumed that reproduction is performed at a predetermined first reproduction speed 801a.

  Here, as in FIG. 8A, a case is considered where the player cannot input properly at the i-th measure of the music. That is, this corresponds to the case where the determination unit 305 does not determine that the degree of matching between the input received by the receiving unit 303 in the i-th measure and the input instruction displayed on the display unit 302 is equal to or greater than the threshold value. . In this case, reverse playback of the music is started by the playback unit 301 at the time when the playback of the music has progressed to the end of the i-th measure, that is, when the input has progressed to 601a at the time of input failure in FIG.

Here, similarly to FIG. 8A, it is assumed that the reverse reproduction is performed from the i-th measure that has failed to be input to the previous i-1th measure. On the graph of FIG. 10A, the graph moves in the lower right direction from the input failure time 601a to the reverse playback end time 602a. In the present embodiment, the reproduction speed at this time remains the predetermined first reproduction speed 801a and does not change.
Then, at the end of reverse playback 602a, playback starts in the forward direction again in the order of the i-1th bar and the i-th bar. In the present embodiment, the playback speed at this time also remains the predetermined first playback speed 801a and does not change.

FIG. 10A shows a case where the player cannot input properly again in the i-th measure (input failure time 601b). Also at this time, as in FIG. 8 (a), the music is reversed from the input failure time 601b at the end of the i-th measure failed the second time to the end of reverse playback 602b at the beginning of the i-1th measure again. Played in the direction. In this embodiment, the playback speed at this time is lowered to a predetermined second playback speed 801b.
Then, the music starts to be played in the forward direction from the end of reverse playback 602b. In the present embodiment, playback is performed at the second playback speed 801b at this time. That is, playback starts in the forward direction at the same speed as the playback speed reversely played until the end of reverse playback 602b.

  FIG. 10A, unlike FIG. 8A, shows a case where the player can input properly in the i-th measure in the third try (when input is successful 603a). At this time, in the first and second embodiments, the playback speed does not return to the original value even after success, and the music is transferred from the successful i-th measure to the previous measure in the order of i + 1-th measure and i + 2-th measure. Has advanced. On the other hand, in the present embodiment, after the successful input 603a, the playback speed returns from the second playback speed 801b up to that time to the original first playback speed 801a. At that time, playback is performed backward once to the beginning of the previous i-1th bar, and playback is started again from the beginning of the i-1th bar.

  That is, on the graph of FIG. 10A, reverse playback is performed at the first playback speed 801a from the successful input 603a to the reverse playback end 602c. Then, the playback is performed in the forward direction at the same first playback speed 801a from the end of reverse playback 602c. When the i-th measure is played back again and is input appropriately by the player (when input is successful 603b), the music playback proceeds to the previous measure in the order of the i + 1-th measure and the i + 2-th measure.

  As described above, in the present embodiment, when the player succeeds in inputting a measure that has been replayed at a reduced playback speed, the reduced playback speed is restored to the original state. That is, in this embodiment, the playback unit 301 reproduces a section that has not been determined to be equal to or greater than the threshold by the determination unit 305, that is, the practice section, and then the instruction associated with the practice section by the determination unit 305. If it is determined that the acquired degree is greater than or equal to the threshold, the playback speed that has been lowered is increased.

  At that time, rather than suddenly returning to the original playback speed (increase the tempo) and proceeding to playback of the previous bar as it is, after returning to the previous bar and then playing back at the playback speed that was restored It is assumed that the player who has proceeded to play the bar after that can play smoothly. For this reason, in this embodiment, after a player succeeds in replaying a measure whose input speed has failed and the playback speed has been reduced, the player performs reverse playback to the beginning of the predetermined measure, and then starts from the beginning of the measure. Play back in the direction.

  Further, in FIG. 10A, the reproduction speed is only changed in one step, that is, a change between the first reproduction speed 801a and the second reproduction speed 801b. However, the present embodiment is not limited to this, and the playback speed may change in a plurality of stages. For example, as in the second embodiment, the playback speed may be gradually decreased as the number of times of failure to play the same measure increases. In this way, when the playback speed is lowered in multiple stages, if the play succeeds in that measure and the playback speed is returned, it will return to the predetermined initial speed when the music playback is started at once. You may return, or you may return gradually, tracing back several steps when the reproduction speed is lowered.

  In the case of gradually returning to multiple stages, the playback unit 301 plays back the bars after the bars that failed to play until the lowered playback speed is gradually increased and finally returns to a predetermined initial speed. Typically not. That is, until the playback speed returns to the predetermined initial speed, the playback unit 301 plays back the measure that has failed to be played again and again, and the playback speed is gradually increased each time the measure is successfully played. Then, after the lowered playback speed returns to the predetermined initial speed, the playback unit 301 plays back the bars after the bar that failed to play. With such a configuration, when the play of the section that the player is not good at fails and the difficulty level is lowered and the game is played, the playback unit 301 plays the music while gradually returning the difficulty level gradually. To do. As a result, the player can focus on the weak sections.

  Furthermore, in the present embodiment, as in the second embodiment, not only the playback speed is changed, but also the difficulty level of the game is adjusted by changing the threshold used by the determination unit 305 to determine success or failure of play. Good. That is, in this embodiment, the playback unit 301 reproduces a section that has not been determined to be equal to or greater than the threshold by the determination unit 305, that is, the practice section, and then the instruction associated with the practice section by the determination unit 305. If it is determined that the acquired degree is equal to or greater than the lowered threshold, the lowered threshold is increased.

  FIG. 10B is a diagram showing an example of the relationship between the elapsed time and the threshold value used for determination in the present embodiment. Also in the graph of this drawing, the elapsed time is taken on the horizontal axis, and the horizontal axis is shared with the graph of FIG. On the other hand, the vertical axis is a threshold value, and the higher the threshold value, the lower the lower threshold value.

In the present embodiment, the threshold used for the determination unit 305 is a predetermined initial threshold, that is, a predetermined first threshold 802a until the player fails to input twice in the same measure. That is, in FIG. 10A, in the elapsed time until the player fails the second time in the i-th measure (input failure time 601b), the threshold is the first threshold as shown in FIG. 10B. It remains unchanged at 802a.
On the other hand, after the second failure, the threshold value is lowered to the second threshold value 802b. That is, in the elapsed time corresponding to the input failure time 601b on the graph of FIG. 10A, the threshold value in FIG. 10B is lowered from the predetermined first threshold value 802a to the second threshold value 802b. Yes. Therefore, when the player plays the i-th measure for the third time, the player can play with a lower threshold used for success / failure determination.
And if it succeeds in the 3rd time, it will return even to the 1st threshold value 802a. That is, in the elapsed time corresponding to the input success time 603a on the graph of FIG. 10A, the threshold value in FIG. 10B is changed from the predetermined second threshold value 802b to the first threshold value 802a, that is, the predetermined initial value. The threshold has been raised. Therefore, the player can play the subsequent play with the threshold value returned to the original.

  In FIG. 10B, the threshold value has only changed in one step, that is, a change between the first threshold value 802a and the second threshold value 802b. However, the present embodiment is not limited to this, and the threshold value may change in a plurality of stages. For example, as in the second embodiment, the threshold may be gradually decreased as the number of times of failure to play the same measure increases. If the threshold is lowered in multiple stages in this way, then play in that measure succeeds, and if the threshold is returned, return to the predetermined initial threshold at the time when playback of the music started at once. Alternatively, it may be gradually returned while following a plurality of steps when the threshold value is lowered.

  When returning gradually in multiple stages, the playback unit 301 does not play back bars after the failed bars until the lowered threshold value is gradually raised and finally returned to the predetermined initial threshold value. It is typical. That is, until the threshold value returns to the predetermined initial threshold value, the reproducing unit 301 reproduces the measure that has failed to be played many times, and increases the threshold value little by little every time the measure is successfully played. Then, after the lowered threshold value returns to the predetermined initial threshold value, the reproducing unit 301 reproduces the bars after the bars that have failed to play. With such a configuration, when the play of the section that the player is not good at fails and the difficulty level is lowered and the game is played, the playback unit 301 plays the music while gradually returning the difficulty level gradually. To do. As a result, the player can focus on the weak sections.

  FIG. 11 is a flowchart showing a process flow according to the game apparatus 300 of the present embodiment. This figure is basically the same as the flowchart described in FIG. 9 in the second embodiment, but the process of restoring the playback speed and threshold (the part surrounded by the dotted line in FIG. 11) is performed in step S107. Newly added during step S108.

  That is, when the game process is started, the game apparatus 300 according to the present embodiment first performs various initial settings (step S101) and starts playing the music (step S102). Then, the playback unit 301 provides a variable n (n is a natural number) for indicating the number of measures, and first substitutes 1 for the value of the variable n (step S103).

  From here, every time the value of the variable n is increased in order, the music is reproduced in chronological order, such as the first measure, the second measure, and the third measure. That is, as long as it is determined as YES in step S107, as in the first embodiment, the music is played to the end in the normal order, and the degree of whether the input made by the player for each measure matches the predetermined instruction is determined. Acquisition is performed (steps S104 to S109).

  Here, in this embodiment, after step S107, it is newly determined whether or not the playback speed and the threshold are lowered (step S301). That is, here, it is determined whether or not the playback speed (tempo) being played back by the playback unit 301 and the threshold value used for determination by the determination unit 305 are lowered from the initial values when the playback of the music is started. judge. Since the playback speed and the threshold cannot be lowered unless the processing in steps S202 and S203 in the flowchart is performed, as long as the music is normally played back in time series, that is, as long as YES is determined in step S107. Here, it is determined that the reproduction speed and the threshold are not lowered (step S301; NO), and the reproduction is continued as it is in time series.

  On the other hand, when NO is determined in step S107, that is, in the n-th measure, for example, the degree of coincidence between the predetermined input instruction and the input from the player is not determined to be equal to or greater than the threshold value, and play within the measure is performed. The flow when the process fails (step S107; NO) will be described below. At this time, similarly to the processing in the second embodiment described above, it is determined for the first time that play has failed in the n-th measure (step S201), and when it is determined that it is not the first time (step S201; NO), the reproducing unit 301. Lowers the playback speed of playing music (step S202), and further lowers the threshold used by the determination unit 305 for determination in step S107 (step S203). Thereafter, as in the first embodiment, the process is reversely reproduced from the nth bar to the beginning of the predetermined bar (steps S110 to S112), and the process returns to step S104.

  That is, if the player fails to input more than once in the n-th measure, the playback speed of the music and the threshold value used for the determination are lowered, that is, in the state where the difficulty level is lowered, the n-th measure (and the n-th measure again). To a predetermined number of bars). When the player succeeds in inputting the nth measure with the playback speed and the threshold lowered (step S107; YES), that is, the degree of coincidence between the predetermined input instruction and the input from the player is lowered. When it is determined that the threshold value is exceeded (step S107; YES), in this embodiment, the determination in step S301 is determined that the playback speed and the threshold value are lowered from the initial values (step S301; YES). .

  At this time, the playback unit 301 returns the playback speed at which the music is played back (step S302), and the determination unit 305 returns the threshold used for the determination (step S303). Thereafter, returning to step S104, the same nth bar is reproduced once again, and then the process proceeds to the reproduction of the previous n + 1th bar and n + 2th bar.

  In the present embodiment, as in the first and second embodiments, the player fails to input in the n-th measure, and is played back to the beginning of, for example, the (n-1) -th measure. When the playback is performed in the order of the n-th measure, the determination unit 305 does not have to determine the n−1-th measure. That is, in step S107, it is assumed that the process for determining whether or not the play in the measure has succeeded is performed only for the nth measure that the player has failed. You may decide not to process. By doing so, it is assumed that the player can concentrate on the play of the failed n-th measure, and can easily practice a measure that is not good at it.

  Further, the processing in steps S302 to S303 may be performed only for the n-th measure in which the player has failed, and may not be performed when the measure that should have already succeeded is repeated. That is, for example, when the player fails to input at the n-th measure and is played back in reverse order up to a predetermined number of measures, for example, the first of the (n-1) th measure, and then played back in the order of the (n-1) -th measure and the n-th measure In addition, the player plays the game for each measure with the playback speed and threshold value lowered. At this time, the measure in which the player has failed is the n-th measure, and the (n-1) -th measure is the measure that should have been successful. Therefore, while the (n-1) -th measure is being played back (the n-th measure is played back). Until the playback speed and threshold are restored.

  Further, in the present embodiment, as in the second embodiment, the reproduction speed and the threshold value are not limited to be increased and adjusted simultaneously. In other words, the difficulty level of the game may be adjusted by changing the playback speed without changing the threshold value. Conversely, the difficulty level of the game may be adjusted by changing the threshold value without changing the playback speed. Also good.

  With such a configuration, in the present embodiment, if the player can appropriately input according to the instruction in the section where the playback speed and the threshold are lowered and replayed, the lowered playback speed and threshold are restored.

  As a result, the player can play at a lower playback speed and threshold for the sections he / she is not good at, and can play at a normal playback speed / threshold for the sections he / she is not good at. In other words, although a weak section can be played with a lower difficulty level, it is not necessary to play with a lower difficulty level to a section that is not good, so that the game can be enjoyed more comfortably.

  As described above, it is possible to provide a game device, a game device control method, and a program that are suitable for supporting the improvement of the player in a game in which the player performs an operation input in accordance with the reproduction of music.
