DETAILED DESCRIPTION OF THE INVENTION
[Configuration of Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a game device according to an embodiment of the present invention, in which (a) is a front view thereof and (b) is a right side view thereof. The game apparatus according to the present embodiment includes a main body unit 10 provided with a control unit 1 and the like, and an electronic guitar 20 as input means. The main body 10 includes a 29-inch display 11, two types of speakers 12 for high and low sounds, an operation unit 13 on which various operation buttons are arranged, and spots provided on both sides of the signboard on the top. And a light 15.
[0014]
FIG. 2 is a detailed view of the electronic guitar 20. As shown in FIG. 2, the electronic guitar 20 includes twelve fret switches 21 using a pressure sensor, one string switch 22, a mute switch 23 using a pressure sensor, an arm 24 with a volume, Have The fret switch 21 corresponds to a portion separated by a fret which is a protrusion that divides the surface of a bowl-shaped base plate that holds a string on an actual guitar, and the string switch 22 corresponds to a string part of the guitar. is there. In the electronic guitar shown in FIG. 2, for the convenience of explanation, numbers from 1 to 12 are assigned to the fret switches in order from the right side. For example, a small protrusion is formed on the fifth fret switch so that it can be understood by touching it with a finger. The mute switch 23 is for simulating an actual guitar mute performance. After playing the string switch, you can stop the sound by pressing the mute switch with the palm of your right hand, and by playing the string switch while pressing the mute switch, you can play the same mute performance as an actual guitar. When the player presses the mute switch, the timbre width is widened, and the feeling when playing the electronic guitar can be made closer to the real thing. The arm 24 is a tremolo arm for applying vibrato to the sound. The player can assert himself like a real guitar by applying vibrato at any timing. When the player presses the fret switch and plays the string switch, the chord corresponding to the pressed fret switch is reproduced from the speaker of the main body. In other words, in this game device, the player plays the chords that are difficult to play on the guitar, since the player plays the string switch by playing the string switch and the same 6 strings of sound as the actual guitar is played. it can.
[0015]
FIG. 3 is an enlarged view of the string switch 22 of the electronic guitar 20. The string switch 22 is rotatable as shown in FIG. 3, and its movement is transmitted to an analog volume (string volume), and the amount of movement moved by being bounced is converted into a digital value and sent to the controller 1. It is done. Assuming that the neutral position is 0, the control unit 1 is supplied with data in the fluctuation range as indicated by the arrow in FIG. FIG. 4 is a diagram for explaining the output of the chord volume, where time is taken on the horizontal axis and output value is taken on the vertical axis. Based on this data, the control unit 1 determines the timing of the performance by the player and reproduces the sound. By the way, assuming that a string of a real guitar is played, first, as shown in FIG. 5, the string is applied to the finger (1) to generate tension. Next, (2) the finger releases the string tension and generates a sound. And (3) the string returns to the original. Thus, a real guitar emits sound through three processes. These three processes are represented by the operation of the string switch 22 as shown in FIG. Such an operation of the string switch 22 is transmitted to the string volume, and the output of the string volume is displaced as shown in FIG. This displacement is further sent to the control unit 1 as multivalued data that is cut every 1/60 seconds. In a conventional apparatus using a guitar as an input means, a sound is generated at timing (1). However, in such a method, the sound generation timing is different from the actual sound generation timing of the guitar, which makes the player feel uncomfortable. On the other hand, in the present embodiment, the control unit 1 takes the difference between the sent multi-value data and the latest data for each data, and reproduces the sound when the difference becomes negative. . That is, in the present embodiment, the sound is reproduced at the timing (2) close to the actual guitar timing, so that it is possible to give the player the same feeling as when actually playing the guitar.
[0016]
Also, in an actual guitar, the sound is produced differently when you play the strings from top to bottom and when you pull from bottom to top, so when you play the string switch from top to bottom and from bottom to top. Different sounds may be played depending on when they are played. In the present embodiment, this performance method does not affect the score and does not give a performance instruction to that effect. Of course, this rendition style may be displayed and added to the score.
[0017]
FIG. 7 is a control block diagram of the present embodiment. The electronic guitar 20 includes a pressure sensor 21a provided in the fret switch, an analog / digital converter 21b that binarizes the output value of the pressure sensor with a predetermined threshold, and a signal from each analog / digital converter 4 bits. From an encoder converter 21c for converting the data into a string, a string volume 22a that moves in conjunction with the string switch 22, an arm volume 24a that moves in conjunction with the arm 24, and a pressure sensor 23a provided in the mute switch 23. The analog-to-digital converter 23b converts the analog signal from analog to digital with a predetermined threshold. It doesn't make sense to hold down two or more fret switches. When the player presses two or more fret switches, it is sufficient to reproduce the fret switch sound close to the root side. Accordingly, in order to indicate the state of 0 in which any one of the fret switches is pressed from 0 in which the fret switch is not pressed, it is only necessary to be able to identify 0 to 12, so the data width of the output of the encode converter 21c is 4 bits. I just need it.
[0018]
In addition to the control unit 1, the main body unit 10 includes an amplifier 4 and a display 29. The control unit 1 reads out and executes a ROM 1c that stores a game control program, a RAM 1b that temporarily stores various input data, calculation results, and the like, and a control program stored in the ROM 1c, thereby executing the entire game. A system board 2 having a CPU 1a that controls the sound source, a sound source 1d, and an input / output board 3. Data from the string volume 22a and the arm volume 24a is sent to the input / output board as multi-value data, and data from the encode converter 21c and the analog / digital converter 23b is sent to the input / output board as binary data. The CPU 1a reads the control program recorded in the ROM 1c and generates a screen to be displayed on the display based on various data sent from the electronic guitar. In the present embodiment, a musical score object (to be described later) or a character with a rubber ball jumping (hereinafter also simply referred to as a spear character) is displayed on the screen. Further, the CPU 1a sends data to the sound source 1d to instruct the sound reproduction. The sound source 1d samples and stores the sound when the actual guitar chord is played in advance, and reproduces the sound of the corresponding guitar according to the instruction of the CPU 1a. Therefore, the player can play the chord of the guitar and enjoy the reproduced sound of the guitar by operating the fret switch 21 and the string switch 22 of the electronic guitar 20.
[0019]
FIG. 8 is a flowchart for recognizing that the string switch has been played. In step S1, the value of the string volume and the rate of change are monitored. When the string volume is monitored, it is determined whether or not the absolute value of the string volume is greater than or equal to a reference value (step S2). If it is equal to or less than the reference value, there is no need to make a sound, and the process returns to step S1. If it is equal to or greater than the reference value, the process proceeds to step S3, and it is determined whether or not the speed of change of the string volume is equal to or greater than the reference value. If the rate of change is below the reference value, for example, if the string is changed slowly, no sound will be produced even with an actual guitar. Therefore, even in this embodiment, the process returns to step S1 without reproducing the sound. Continue monitoring. If it is determined in step S3 that the value of the string volume changes at a speed equal to or higher than the reference value, the process proceeds to step S4 to determine whether or not the change in the value of the string volume is reversed from increase to decrease. If not reversed, the process returns to step S1, and if reversed, the sound source 1d is requested to reproduce the sound corresponding to the pressed fret.
[0020]
[Performance Method] Next, a method of performing using the electronic guitar with this game apparatus will be described. A selection button provided on the operation unit 13 is used to select whether to play alone or two, and press a game start button. When the play by one person is selected, the screen shown in FIG. 9 is displayed on the display. When the play by two persons is selected, the screen shown in FIG. 10 is displayed on the display. Below, in order to simplify description, it demonstrates with reference to the screen at the time of making it play alone, but when playing with two persons, it can play by the same method.
[0021]
In the screen shown in FIG. 9, a musical score object 30, a timing line 31, and a spear character 32 are displayed at the top, an electronic guitar image 33 is displayed at the center, and a physical strength meter 34 is displayed at the bottom. The musical score object 30 is drawn to resemble the surface of a bowl-like base plate of a guitar, the narrow portion 30a is a portion indicating the start of a sound, and the region 30b is a portion displaying a fret switch that the player wants to press. It is. For convenience of explanation, the narrow portion 30a is referred to as a fret image portion. The numerical value given to the fret image section corresponds to the fret switch number of the electronic guitar. Each region 30b corresponds to a guitar chord. The musical score object is scroll-displayed by the CPU from the left side to the right side of the screen. The twelve fret switches displayed on the electronic guitar image 33 are actually color-coded in different colors so that they are easy to see. The physical strength meter 34 gradually decreases if the wrong performance is performed, and the game is over when the physical strength meter becomes zero.
[0022]
FIG. 11 is an enlarged view of a musical score object for explaining performance timing. The player presses the fret switch designated by the musical score object scroll-displayed from the right side to the left side on the screen, and plays the string switch at the moment when the fret image portion of each area of the musical score object overlaps the timing line. In the state of FIG. 11A, the number 5 is attached to the fret image portion, and the fifth area is displayed in a color corresponding to the fret (in FIG. 11, shaded hatching). Hold the th fret switch with your finger. As shown in FIG. 5B, the screen is scrolled and the string switch is played at the moment when the fifth fret image section overlaps the timing line. If you press the wrong fret switch or play the wrong timing, the health meter will decrease, and if the health meter runs out, the game will be over at that moment. If the song is played before the health meter runs out, the stage is cleared and the next song can be played. Further, in the present embodiment, the fret to be pressed is not only indicated by the musical score object, but also indicated by adding a triangle mark in the vicinity of the corresponding fret of the electronic guitar image 33 on the screen as shown in FIG. The Thus, even a beginner can easily play difficult guitar chords. In this embodiment, when the player presses the wrong fret switch and plays the string switch, the wrong sound is produced.
[0023]
In the present embodiment, an object having a color corresponding to the fret pressed by the player may be displayed. Thereby, the player can easily confirm whether or not the fret held by the player is correct.
[0024]
FIG. 12 is an enlarged view of a musical score object for explaining release. In this game apparatus, the concept of “sound length” is introduced. The extended sound can be cut off by releasing the pressed fret switch, pressing a new fret switch inside the pressed fret switch, or pressing the mute button. FIG. 12A shows a state in which the fret image portion and the timing line overlap each other, and the player plays the string switch in this state. As a result, sound is reproduced. If the fret switch is pressed with a finger until the state (b), the reproduction is continued. Then, when the timing line is positioned at the end of the area as shown in (c) and the fret switch is released, the reproduction ends. The upper and lower hands of this release may be reflected in the physical strength meter.
[0025]
[Rhythm removal technique] Next, a technique for teaching the player the rhythm will be described. In a game device that performs a conventional performance, only a mistake is reported to a player who cannot take a rhythm. For this reason, the player did not know how to improve. Therefore, in the present embodiment, the display is made easy for the player to take a rhythm, and the device is devised to raise the aspiration to improve by giving the player the contents of the mistake.
[0026]
In this embodiment, in order to make it easy for the player to take timing, an image such as a jumping kite is displayed on the screen at a place where the player can easily enter the field of view, in the example shown in FIG. 9, at the left corner of the score object. If the jumping kite is programmed so as to move up and down by drawing a parabola as shown in FIG. 13 in accordance with the laws of nature, it becomes easier for the player to take a rhythm. In FIG. 13, the horizontal axis represents time, and the vertical axis represents the position of the frog character. The movement of this spear is satisfactory even in the light of the command method of the orchestra. This spear character is
y = -at ² + Bt (a> 0, 0 <t <b / a)
Repeat the vertical movement according to the following formula. The player can play the string switch with good timing by watching the character of the kite and playing the string switch at the timing when the character of the kite is located at the bottom. Thus, even a beginner can easily perform a guitar performance that matches the rhythm.
[0027]
Next, a method for causing the player to recognize a rhythm error will be described. FIG. 14 is a diagram for explaining a method of informing a player of a rhythm error. When the player presses the fifth fret switch and plays the string switch, if the timing is earlier than the correct timing, the character “fast” is displayed in the vicinity of the fifth area, and the player plays further. The timing is displayed with a triangle mark on the left side of the fret image portion, away from the fret image portion, depending on how fast it is. If the playing timing is later than the correct timing, the word “late” is displayed, and the timing of the player's playing is displayed on the right side of the fret image section with a triangle mark and separated from the fret image section depending on the degree of delay. To display. In the case shown in FIG. 14, since the timing when the fifth fret switch is pressed is early, a triangle mark is displayed on the left side of the fifth fret image section. Thus, if the player can recognize whether the rhythm played by the player is early or late, the player can easily correct the rhythm with the next sound. In addition, by telling the player whether the rhythm is fast or slow, the player is presented with an improvement path, so that improvement is born. Furthermore, since the player can know “how fast or slow”, the correction range can be known, and further improvement can be stimulated.
[0028]
[Nori evaluation method] Next, the nori evaluation method will be described. In the prior art, when evaluating the goodness of the rhythm, only the degree of deviation from the time axis relative to the absolute time axis was evaluated. However, there is a kind of music called “Nori”, and there is a limit to evaluating the player's sense of rhythm with the conventional evaluation method. For example, when three players perform as shown in FIG. 15 with respect to a reference absolute rhythm, in the conventional evaluation method, an evaluation of (player 1) = (player 2) <(player 3) is performed. become. However, the player 2 has a stable rhythm, and simply has a deviation from the given absolute rhythm (this performance is referred to as “backward”). For example, the evaluation should be (player 1) <(player 2) = (player 3). In the present embodiment, in order to evaluate this “groove” portion, statistics of “how much” is taken with respect to an absolute rhythm. The smaller the variance is, the higher the score is, and the bonus score is given so as to evaluate the “pitch”. FIG. 16 is a diagram showing the result of taking statistics of how much a certain music is deviated. In FIG. 16, the horizontal axis indicates the timing shift and the vertical axis indicates the number of times. The case shown in FIG. 6 (a) is a performance called a so-called pre-pitch, and a high score is given to such a player. In the case shown in FIG. 5B, the rhythm is taken at the correct timing, and a high score is given as in the conventional case. The case shown in FIG. 5C is a so-called post-soil performance, which also gives a high score. In the case shown in FIG. 4D, since the rhythm is scattered, a low score is given to the player who performed such a performance.
[0029]
Next, a specific method for evaluation of the glue will be described. In the game of the present embodiment, the screen is switched in 1/60 second, and the input can be detected in 1/60 second increments when the screen is switched. Also, what seems to be on the rhythm of music is from +1/60 seconds to -1/60 seconds, based on experience, depending on the tempo of the song. If it deviates more than this, it is understood that the timing is deviated while listening to the sound. Therefore, in the present embodiment, A: when the rhythm is 1/60 seconds earlier, B: when the rhythm is just right, and C: when the rhythm is 1/60 seconds later, it is determined that the performance is riding on the rhythm. I decided to. The number of sounds played at each timing is designated as NA, NB, NC.
(MAX (NA, NB, NC) -MIN (NA, NB, NC)) x (constant)
Bonus points are calculated according to the following formula. Bonus points are calculated by multiplying a value obtained by subtracting the minimum value of NA, NB, and NC from the maximum value of NA, NB, and NC, and the calculated bonus points are added to the score. By using such a calculation formula, the highest score is obtained when all inputs are at any timing of A, B, and C, and the lowest score is obtained when the average is distributed at all timings. Since it takes time to obtain the variance, in the present embodiment, the above-described simple method is used in order to evaluate a normal performance at high speed. As in the present embodiment, by evaluating the groove, the performance of “before” and “after” can be evaluated as a stable rhythm.
[0030]
FIG. 17 is a flowchart for evaluating the groove. When a sound is played by the player (step S1), it is checked in step S2 whether an accurate sound is played at an accurate timing (within ± 1/60 seconds with respect to the instructed timing). If an accurate sound is played at an accurate timing, the process proceeds to step S3 to determine whether or not the timing shift is early. If the timing is not early, the process proceeds to step S4 to determine whether the timing is late. When the timing is not late, the process proceeds to step S5, and the value of the counter NB for the case where the rhythm is just right is increased by one. In step S6, it is determined whether or not the performance is finished. If the performance has not ended, the process returns to step S1 to perform the next input process. If the performance has been completed, the process proceeds to step S7, and a bonus calculation for laver evaluation is performed. If it is determined in step S3 that the timing is early, the process proceeds to step S8, the value of the counter NA for the case where the rhythm is 1/60 seconds earlier is incremented by 1, and the process proceeds to step S6. Then, the same processing as described above is performed. If it is determined in step S4 that the timing is late, the process proceeds to step S9, the value of the counter NC for 1/60 later is incremented by 1, and the process proceeds to step S6. Then, the same processing as described above is performed. In this way, the values of NA, NB, and NC at the end of the performance of one piece of music are obtained, and the bonus point for evaluation of the score is calculated using the above formula.
[0031]
[Tapping simulation] Next, tapping simulation will be described. In an actual guitar, there is a technique called tapping (light hand). This performance method is a performance method in which the right-handed performance method is called hammering pulling, and is basically hammering pulling. Here, hammering is a technique in which the first sound is picked and the next sound is played by striking another position on the same string with a finger. Pulling refers to a technique that produces a sound by releasing the finger as if it was “hooked” when it is released from the string.
[0032]
In the game of this embodiment, this tapping can be performed in a pseudo manner. Thereby, even a beginner can easily perform a difficult tapping performance. In the present embodiment, the normal performance method and the tapping performance method are distinguished and played. When shifting to the tapping performance method, a display to that effect (display indicating that the mode has shifted to the tapping mode) is performed on the screen. The instruction of the tapping performance method is performed by displaying characters or by changing the color of the corresponding area of the musical score object on the screen. Even if the player performs tapping when the tapping mode is not displayed, the performance is invalid.
[0033]
FIG. 18 is a flowchart when the mode is shifted to the tapping mode. In step S1, it is displayed on the screen that the tapping mode is set, and the mode is shifted to the tapping mode. In step S2, it is determined whether or not any sound is being played. Even when the mode is shifted to the tapping mode, if the player plays the string switch, the process shifts to step S3 to reproduce the corresponding sound and returns to step S1. In the present embodiment, even when the mode is shifted to the tapping mode, the player can reproduce a normal sound by playing the string switch. If it is determined in step S2 that the string switch has not been played, the process proceeds to step S4 to determine whether hammering is performed. That is, when it is detected that a higher fret switch is pressed without removing the finger from the currently pressed fret switch, the process proceeds to step S5, and sampling is performed for hammering the pressed fret switch. Play the recorded sound. Then, the process returns to step S1. If it is not hammering in step S4, the process proceeds to step S6 to determine whether it is pulling. That is, when the finger is released from the currently pressed fret switch in a state where the fret switch that is lower than the currently pressed fret switch is pressed, it is determined that there is a pulling, and the process proceeds to step S7. Play the sampled sound for the fret switch pulling. If it is determined in step S6 that it is not pulling, the process proceeds to step S8 to determine whether or not the mute switch has been touched. If the mute switch is touched, the process proceeds to step S9 to stop the sound. If the mute switch is not touched, the process returns to step S1 and the above-described processing is repeated. This process is performed for a predetermined period, and after the period ends, the display of the tapping mode on the screen is turned off, and the game mode is controlled by returning to the normal mode.
[0034]
[Operation of Embodiment] Next, an outline of the operation of this embodiment will be described with reference to FIG. FIG. 19 is a schematic flowchart of this embodiment. When a predetermined number of coins are inserted and the start button on the operation unit is pressed, this flow is executed. Note that the player inputs sounds such as bass and lead guitar, which are some parts of the music, and the sounds of other parts are reproduced by the control unit 10. In step S1, it is determined whether the difficulty level of beginner or advanced is selected. When the beginner level is selected, the process proceeds to step S2 to determine which song is selected as the first song for the beginner level. The player selects a song he / she wants to play from 20 to 30 songs prepared in advance. In step S3, the music selected by the player is played. The image shown in FIG. 9 is displayed on the display screen, and the musical score object is scroll-displayed. If the player performs well, that is, if the player can perform well and the physical strength meter remains before the first music is played, the process proceeds to step S4, and whether or not the second music is selected. Judging. In step S5, the second music piece is played in the same manner as the first music piece. If the second song is also played well, the process proceeds to step S6, where evaluation, ranking and ending are displayed. Evaluation is performed, for example, with a maximum score of 100. At this time, bonus points based on the evaluation of the glue are added. In addition, this performance is compared with performances performed in the past, and the ranking of the player is displayed. Then, the fact that the game has ended is displayed on the screen. On the other hand, if the performance is mistaken during the performance of step S3 or step S5 and the physical strength meter becomes zero, the process proceeds to step S6, the same processing as described above is performed, and the end of the game is displayed.
[0035]
Further, when the advanced level is selected in the difficulty level selection in step S1, the process proceeds to step S7 to select the first song. In step S8, the first song is played. If the player can perform well and the physical strength meter remains, the process goes to step S9 to select the second music piece. In step S10, the selected second music piece is played. If the second music can be played well, the process proceeds to step S11 and the third music is selected. In step S12, the third song is played. If the performance of the third song can be performed well, the process proceeds to step S6, and evaluation, ranking, and ending are displayed. In addition, when the performance of the third song is finished in step S12, it is determined whether or not the player is an excellent player, and the player who has an excellent player is given an opportunity to perform an extra performance. If the grade is excellent, a song for extra performance is selected in step S13. In step S14, the extra performance is performed, and the process proceeds to step S6 where evaluation, ranking, and ending are displayed. Since this game takes about 90 seconds per song, the time required for one game is about 5 minutes.
[0036]
[Effects of the Embodiment] According to the game device of the present embodiment, the musical score displayed on the screen even if the musical score cannot be read, the difficult guitar chord is not known, or the rhythm is worse. You can play the guitar that matches the rhythm by watching the object and the character of the kite. In addition, according to the present game device, since the timing deviation when the player performs is displayed, the player can know whether his performance timing is too early or too late. It is possible to perform in accordance with the rhythm and to further improve the performance technique.
[0037]
In addition, according to the game device of the present embodiment, so-called “previous” and “rear” are also evaluated as appropriate performances, so that the game can be enjoyed in a form closer to actual performance. .
