Description

  The present invention relates to a game apparatus suitable for producing a sense of reality in accordance with a player's results in a game apparatus that reproduces sound, a game control method, and a program for realizing these on a computer.

  Conventionally, in a competitive game such as soccer or baseball, a method of displaying the audience on the screen or outputting cheers or applause according to the progress of the game is used in order to produce a realistic feeling of the game. It has been. For example, Patent Document 1 discloses an invention in which the number of spectators is adjusted and displayed on a screen according to the progress of a game and the attributes of characters, and the cheer and applause of the number of sound sources according to the number of spectators are output. .

Japanese Patent No. 3448044

  However, there is a strong demand to produce a more realistic sensation of the game by appropriately outputting sound according to the player's performance. The present invention solves the above-described problems, and in a game device that reproduces sound, a game device, a game control method, and the like that are suitable for creating a sense of reality according to the player's results. Provide a program to be realized.

  A game device according to a first aspect of the present invention includes a reproduction unit, an evaluation unit, and an adjustment unit, and is configured as follows.

  The reproduction unit reproduces the main sound and the related sound.

  For example, the singer's singing voice or song is played as the main voice, and the audience's voice, applause, clapping, etc. are reproduced as the related voice.

  The evaluation unit evaluates the performance of the player according to a predetermined evaluation standard every time there is an input by the player.

  For example, in a dance game, an average value of results for a period of one measure is used as an evaluation criterion. Then, every time the player steps on the step, the average value of the results of the step input during one measure is obtained.

  The adjusting unit adjusts the volume at which the related sound is reproduced according to the player's score evaluated according to the evaluation criteria.

  For example, when the average value of the results for one measure is high, the applause playback volume is set high, and when the average value of results for one measure is low, the applause playback volume is set low.

  According to the present invention, it is possible to produce a realistic sensation of the game by adjusting the playback volume such as a shout or applause that is played according to the player's performance.

  The related sound includes a first sub sound and a second sub sound, and the evaluation unit evaluates the performance of the player based on the first evaluation standard and the second evaluation standard every time the player inputs. The adjusting unit adjusts the volume at which the first sub-audio is reproduced according to the player's score evaluated according to the first evaluation criterion, and according to the player's score evaluated according to the second evaluation criterion. Thus, the volume at which the second sub-audio is reproduced may be adjusted.

  For example, the first sub-voice is shouted, the second sub-voice is applause, the first evaluation criterion is the average value of the period of one bar, and the second evaluation criterion is the average value of the period of three bars And That is, the playback volume of the shout is adjusted according to the level of the average value between 1 bar, and the playback volume of the applause is adjusted according to the level of the average value between 3 bars.

  The present invention relates to a preferred embodiment of the above invention, and the reproduction volume of a plurality of sub-sounds can be adjusted according to different evaluation criteria.

  In addition, the score based on the first evaluation standard is determined by the player's input during the first most recent period, and the score based on the second evaluation standard is determined based on the player's input during the second most recent period. The timing at which the sound is to be reproduced is predetermined with respect to the elapsed time from the start of the reproduction of the main sound, and the timing at which the second sub-audio is to be reproduced is from the start of the reproduction of the main sound. It may be determined in advance for the elapsed time.

  For example, the timing to reproduce the shout and applause is determined in advance, and the replay volume of the shout is adjusted according to the average value of the player's results in one measure (first immediate period) immediately before playing the shout, The playback volume of the applause is adjusted according to the average value of the player's results in the three bars (second most recent period) immediately before the applause is played.

  The present invention relates to a preferred embodiment of the above-described invention, and since it is possible to adjust the reproduction volume of the sub-sound based on the result of the most recent period of reproducing the sub-sound, the player can immediately correspond to the player's result. The volume can be adjusted.

  In addition, the elapsed time from the start of the reproduction of the main sound is divided every time length same as that of the first most recent period, and the timing at which the first sub-audio is to be reproduced is the player within the divided period. Is determined immediately after a period in which the number or frequency of input of the number exceeds a predetermined threshold.

  For example, a song (main audio) is divided into bars of a predetermined length, and the number of steps required in the bar exceeds a predetermined threshold, that is, immediately after a period of relatively high difficulty of play, A shout is played.

  The present invention relates to a preferred embodiment of the above-described invention, and the higher the performance in the period of high difficulty, the higher the volume of the voice is played, so that the audience is excited about the player's play It is possible to produce a production.

  Further, the first sub-audio may be reproduced during a predetermined period of the total period during which the main audio is reproduced.

  For example, the voice is played back from the beginning to the end of the music (total period) after an interlude part where the singing voice is not played back or after the last sound of each measure is played back (predetermined period).

  The present invention relates to a preferred embodiment of the invention described above, and by limiting the period during which the sub-audio is reproduced, it is possible to produce an effect that the audience is singing to the music.

  Further, the second sub audio may be reproduced in accordance with the rhythm of the main audio to be reproduced.

  For example, the applause is reproduced in accordance with the rhythm of the singing voice like the clapping.

  The present invention relates to a preferred embodiment of the above invention, and can produce an effect that the audience is clapping in time with the music.

  Further, the length of the first most recent period may be shorter than the length of the second most recent period.

  For example, the playback volume of the shout is adjusted according to the average value of the scores in one measure immediately before the shout is played, and the playback volume of the applause is the average value of the scores in three measures just before the applause is played. Is adjusted according to.

  The present invention relates to a preferred embodiment of the above invention, wherein the playback volume of one sub-speech is adjusted in response to the change in the score immediately, and the playback volume of the other sub-sound is adjusted with respect to the change in the score. It can be adjusted gently.

  Further, any one of a plurality of predetermined candidate sounds may be selected according to the player's score evaluated in the first most recent period, and the selected candidate sound may be reproduced as the first sub sound. Good.

  For example, a call or cheer calling the singer's name is prepared as a candidate for the sub-sound played in the interlude part, and the call or cheer calling the singer's name is played according to the result immediately before the interlude part.

  The present invention relates to a preferred embodiment of the above invention, and the sub-sound can be changed according to the result for each period of reproduction.

  A game control method according to another aspect of the present invention includes a reproduction process, an evaluation process, and an adjustment process, and is configured as follows.

  In the reproduction process, the reproduction unit reproduces the main audio and the related audio.

  In the evaluation process, the evaluation unit evaluates the performance of the player according to a predetermined evaluation standard every time there is an input by the player.

  In the adjustment step, the adjustment unit adjusts the volume at which the related sound is reproduced according to the player's performance evaluated according to the evaluation criteria.

  A program according to another aspect of the present invention is configured to cause a computer to function as the game device and to cause the computer to execute the game 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.

Further, under the control of the CPU 101, sound effects and music data to be generated during the progress of the game are generated, and sound corresponding to this is output from the speaker.

  When the audio data recorded on the DVD-ROM is MIDI data, the audio processing unit 111 refers to the sound source data included in the audio data and converts the MIDI data into PCM data. If the compressed audio data is in ADPCM format or Ogg Vorbis format, it is expanded and converted to PCM data. The PCM data can be output by performing D / A (Digital / Analog) conversion at a timing corresponding to the sampling frequency and outputting it to a speaker.

  In addition, the information processing apparatus 100 uses a large-capacity external storage device such as a hard disk so as to perform the same functions as the ROM 102, the RAM 103, the external memory 107, the DVD-ROM attached to the DVD-ROM drive 109, and the like. You may comprise.

  The information processing apparatus 100 described above corresponds to a so-called “consumer video game apparatus”, but the present invention can be realized as long as it performs image processing to display a virtual space. Therefore, the present invention can be realized on various computers such as a mobile phone, a portable game device, a karaoke apparatus, and a general business computer.

  For example, a general computer includes an CPU, a RAM, a ROM, a DVD-ROM drive, and an NIC as in the information processing apparatus 100, and an image processing unit having a simpler function than the information processing apparatus 100. In addition to having a hard disk as an external storage device, a flexible disk, a magneto-optical disk, a magnetic tape, and the like can be used. Further, not the controller unit 105 but a keyboard or a mouse is used as an input device.

  Next, a functional configuration of the game device according to the present embodiment realized in the information processing apparatus 100 will be described with reference to FIG. When a DVD-ROM storing a game program and data is loaded into the DVD-ROM drive 109 and the information processing apparatus 100 is turned on, the program is executed, and the game apparatus according to the present embodiment is realized. Is done.

  A game device 301 according to the present embodiment includes a reproduction unit 302, an evaluation unit 303, and an adjustment unit 304, and executes a game as shown in FIG.

  In the game image of FIG. 4, a plurality of types of target objects MO1 to MO4 appear in sequence from below along the movement lane La (lane corresponding to the type of object) in synchronization with the rhythm of the music to be played back. Each of them is shown moving up and disappearing. Each target object MO1 to MO4 represents an arrow symbol in a different direction, and the direction of each target object MO1 to MO4 indicates the direction of the step that the player should step on.

  These target objects MO1 to MO4 appear from the lower end (starting point) of the moving lane La, move upward in the moving lane La, and disappear at the upper end (ending point) of the moving lane La. The player is requested to perform an action corresponding to the target object at a timing when any one of the target objects MO1 to MO4 reaches the determination area HA (an area in which an object having the same shape as each target object is fixedly arranged). The That is, the player is required to step on the button 201 of the mat type controller 106 in the direction indicated by the target object when the objects are exactly overlapped in the determination area HA.

  Therefore, when the target object MO1 that is a right-pointing arrow symbol overlaps with an object in the determination area HA, an operation of stepping on the button 201R of the mat-type controller 106 is required. Similarly, in the case of the target object MO2 that is a downward-pointing arrow symbol In the case of the target object MO3 that is the symbol of the upward arrow, the operation of stepping on the button 201U or the button 201L in the case of the target object MO4 that is the left arrow symbol is required.

  When the player steps on the button 201 in the indicated direction when the objects are exactly overlapped in the determination area HA, the score is added, and for example, the score is displayed on the screen as “123400” in FIG. On the other hand, when the objects are exactly overlapped in the determination area HA, the score is subtracted when there is no input by the player or when the step is not stepped in the indicated direction. Further, the smaller the error between the timing when the step is taken and the timing when the objects are exactly overlapped in the determination area HA, the higher the score may be obtained.

The game image in FIG. 4 shows a case where the target objects MO1 to MO4 move from the bottom to the top of the screen, but the movement direction of the target object is not limited to this and is arbitrary. For example, the screen 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 screen or from the left side to the right side of the screen). Further, instead of the determination area HA, a determination line orthogonal to the moving lane La may be displayed and used as an area for determination. The moving lane La may be hidden in the game image.
Further, the shape of the target object is an example, and may be another shape.

The reproduction unit 302 reproduces the main sound synchronized with the game image, the first sub sound, and the second sub sound. Based on the result of play notified by the evaluation unit 303, the reproduction unit 302 selects the first sub-audio from among a plurality of candidate sounds stored in the RAM 103 or the like, and the volume specified by the adjustment unit 304 Thus, the first sub audio is reproduced. Also, the playback unit 302 plays back the second sub-audio stored in the RAM 103 or the like with the volume specified by the adjustment unit 304.
Therefore, the CPU 101 functions as the playback unit 302 in cooperation with the audio processing unit 111.

  In the present embodiment, the playback unit 302 plays back a song that includes a singing voice as the main voice, a shout as the first sub-voice, and applause as the second sub-voice. An example of the music played by the playback unit 302 is shown in FIG. The music shown in FIG. 5 is composed of A melody (the part where the melody is presented first), B melody (the part where the melody different from the A melody is presented), chorus (the most exciting part of the music), interlude, etc. , Separated by multiple bars. Within each measure, the number and timing of steps to be input are set in advance. A plurality of black circles 11, gray circles 12, and white circles 13 in the bar of FIG. 5 indicate the timing at which the target objects MO 1 to MO 4 and the objects in the determination area HA are exactly overlapped. That is, in the period A, four steps are required. Based on the results for the above steps obtained by the evaluation unit 303, the playback unit 302 selects a call to be played from a plurality of calls. Then, the selected voice and applause are reproduced at the volume notified by the adjustment unit 304.

Each time there is an input by the player, the evaluation unit 303 obtains the results of the play made during the first evaluation period and the second evaluation period. Here, the first evaluation period is a period in which the number or frequency of inputs required by the player within a predetermined period exceeds a predetermined threshold. The first sub audio is reproduced immediately after the first evaluation period. Generally, the higher the number of inputs required in a predetermined section, the higher the difficulty level. Therefore, the timing at which the first sub audio is reproduced is determined according to the difficulty level during the game. The second evaluation period is an arbitrary period longer than the first evaluation period, and the second sub-audio is reproduced immediately after the second evaluation period.
Therefore, the CPU 101 functions as the evaluation unit 303.

  For example, as shown in FIG. 5, the music is divided into a plurality of bars, and a value obtained by dividing the number of inputs (steps) required in one music by the number of bars existing in one music is calculated (hereinafter referred to as “average number of inputs”). ). Assuming that the average number of inputs is “3”, the first evaluation period is a period of a bar for which four or more inputs are required within one bar (a period divided in advance). That is, in the example of FIG. 5, each measure that constitutes rust such as periods A and B is the first evaluation period. The shout is played immediately after each measure constituting the chorus in periods A, B, etc. Further, the second evaluation period is set as periods C to F of three bars. The applause is reproduced immediately after the periods C to F.

The adjustment unit 304 adjusts the reproduction volume of the first sub-audio according to the player's score in the first evaluation period obtained by the evaluation unit 303, and the player's score in the second evaluation period obtained by the evaluation unit 303. The playback volume of the second sub audio is adjusted according to the above.
Therefore, the CPU 101 functions as the adjustment unit 304 in cooperation with the audio processing unit 111.

  That is, the adjustment unit 304 adjusts the playback volume of the voice A in FIG. 5 based on the level of the results in the period B and the playback volume of the clap C to F in the same way. Based on the results of C to F, adjust each.

  Hereinafter, operations performed by each unit of the game apparatus 301 will be described. When the game apparatus 301 is powered on and the game is started by the player, the CPU 101 displays a game image as shown in FIG. 4 on the monitor and starts the process shown in the flowchart of FIG.

  When the game is started, the evaluation unit 303 checks the state of input by the player (step S601). The evaluation unit 303 calculates a score based on the state of the input, and adds or subtracts the calculated score to the total score of the game (step S602).

  For example, it is assumed that the white circle 13 in the music shown in FIG. 5 indicates the timing at which the target object MO4 in FIG. 4 and the object in the determination area HA are exactly overlapped, and the player takes steps according to the target object MO4 in FIG. To do. The evaluation unit 303 evaluates whether or not the player's step is performed in the direction indicated by the target object MO4 at an accurate timing, and calculates a score. Also, when the player does not input a step or when the player steps in a direction different from the direction indicated by the target object MO4, a predetermined value is subtracted from the total score of the game.

  Next, the evaluation unit 303 determines whether or not the input timing obtained at the end of the first evaluation period (periods A and B in FIG. 4) has been reached (step S603). When the input timing obtained at the end of the first evaluation period has been reached (step S603; Yes), the evaluation unit 303 obtains, for example, an average value of results for the input made during the first evaluation period ( Step S604). On the other hand, when the input timing required at the end of the first evaluation period has not been reached (step S603; No), the evaluation unit 303 determines whether the timing required at the end of the second evaluation period has been reached. Judgment is made (step S608).

  For example, when the music has reached the timing indicated by the white circle 13 (the input required at the end of the period A) in FIG. 5 (step S603; Yes), the evaluation unit 303 performs the results for the four steps performed in the period A. Is obtained (step S604). The evaluation unit 303 notifies the reproduction unit 302 and the adjustment unit 304 of the average value of the results during the first evaluation period.

  Next, based on the average value of the grades received from the evaluation unit 303, the reproduction unit 302 selects a voice to be played back immediately after the first evaluation period from the voice candidate voices stored in the RAM 103 or the like. . The voice candidate voice includes, for example, a word indicating evaluation of play, a singer's name, a cheer, and the like. For example, if the average value of the grades in the first evaluation period is 90 points out of 100 points, a call such as “Very Good.” Is selected.

  The adjustment unit 304 adjusts the reproduction volume such as a call or applause based on the average value of the results of the first evaluation period received from the evaluation unit 303 (step S606). For example, assuming that the highest point of the average value is 100 points, the lowest point is 0 point, the maximum volume reproduced by the playback unit 302 is 10, the minimum volume is 0, and the playback volume is playback volume = 0.1 × result. Is obtained from the equation (equation (1)). When the average value is 60 points, the reproduction volume is obtained as “6”. The adjustment unit 304 notifies the reproduction unit 302 of the obtained reproduction volume.

  The reproducing unit 302 reproduces the voice immediately after the first evaluation period at the reproduction volume received from the adjusting unit 304 (step S607). For example, if the average value of the results of period A (first evaluation period) is 90 points, the playback unit 302 plays back the selected voice A at a volume “9”.

  Next, the evaluation unit 303 determines whether or not the input timing required at the end of the second evaluation period has been reached (step S608). If the input timing required at the end of the second evaluation period has not been reached (step S608; No), the state of input by the player is continuously examined (step S601).

When the input timing obtained at the end of the second evaluation period (periods C to F in FIG. 5) has been reached (step S608; Yes), the evaluation unit 303 performs the results for the input made in the second evaluation period. For example, an average value is obtained (step S609), and the obtained value is notified to the adjustment unit 304. The adjusting unit 304 obtains the playback volume of the applause from the notified average value (step S610), and notifies the playback unit 302 of the obtained playback volume. The reproducing unit 302 reproduces the sound data of the applause immediately after the second evaluation period with the notified volume (step S611).
Note that the above-mentioned applause volume adjustment and reproduction processing (steps S608 to S611) may be performed in parallel with the call volume adjustment and reproduction processing (steps S603 to S607).

  For example, if the step currently input by the player is performed on the gray circle 12 portion in FIG. 5, the evaluation unit 303 determines the average value (eg, 60 points) for the eight steps obtained within the period C. ) And the adjustment unit 304 obtains the reproduction volume as “6” from the above equation (1). The reproduction unit 302 reproduces the applause C immediately after the period C at a reproduction volume of “6”.

  In the present embodiment, the second sub-sound is applause, but hand clapping can be reproduced in accordance with the rhythm of the main sound to be reproduced.

  In this embodiment, the music is divided into bars. However, the present invention is not limited to this, and the player may arbitrarily specify the time by time.

  According to the present embodiment, it is possible to determine the timing for reproducing the sub-sound according to the number of inputs required within a predetermined period, that is, the difficulty level of play, and a plurality of sub-sounds according to the playing results. You can adjust the volume. That is, the higher the level of play in a period of high difficulty, the higher the playback volume, so that it is possible to produce an effect that the audience is excited about the play.

The game apparatus according to the present embodiment is realized in the information processing apparatus 100.
The game device according to the present embodiment includes the same components as in the first embodiment, but the playback unit 302 and the evaluation unit 303 of the present embodiment are different from the playback unit 302 and the evaluation unit 303 of the first embodiment. I do.

The reproduction unit 302 reproduces the first sub audio and the second sub audio at the volume notified by the adjustment unit 304 together with the main audio. The reproduction timing of the first and second sub-audio is predetermined for the main audio. The playback unit 302 selects the first sub-voice from a plurality of candidate voices based on the play results notified by the evaluation unit 303. Then, the first and second sub-voices selected at a predetermined timing are reproduced.
Therefore, the CPU 101 functions as the playback unit 302 in cooperation with the audio processing unit 111.

FIG. 7 shows an example of music played in synchronization with the game image of FIG. 4 in the present embodiment.
The music in FIG. 7 is composed of an intro, A melody, B melody, chorus, interlude, and ending.
In the present embodiment, it is assumed that the first sub-voice is a shout and the second sub-voice is a clap. The timing at which the voices A and B are reproduced is determined in advance as the timing at which the interludes A and B start, and the timing at which the claps C to E are reproduced at a predetermined interval from the B melody 1. .

The evaluation unit 303 evaluates the results of the first most recent period and the second most recent period every time there is an input by the player. Here, the first most recent period is a predetermined period immediately before the first sub-audio is reproduced. The second most recent period is a predetermined period immediately before the second sub-audio is reproduced, and is a period longer than the first most recent period. In the present embodiment, the first immediate period is a chorus period (periods A and B) before the shout is reproduced, and the second immediate period is a period longer than the chorus period before applause is reproduced. (Periods C to D)).
Therefore, the CPU 101 functions as the evaluation unit 303.

  Hereinafter, the operation performed by each unit of the game apparatus 301 will be described using a dance game as an example. When the game apparatus 301 is powered on and the game is started by the player, the CPU 101 displays a game image as shown in FIG. 4 on the monitor and starts the process shown in the flowchart of FIG.

  When the game is started, the evaluation unit 303 examines the input state by the player (step S801). The evaluation unit 303 calculates a score based on the state of the input, and adds or subtracts the calculated score to the total score of the game (step S802).

  Next, the evaluation unit 303 determines whether or not the music reaches the interlude period (step S803). When the music piece reaches the period of the interlude (step S803; Yes), the evaluation unit 303 obtains, for example, an average value of the results for the input in the first most recent period that is the period immediately before the interlude (step S804), and The value is notified to the reproduction unit 302 and the adjustment unit 304. On the other hand, if the music does not reach the interlude period (step S803; No), the evaluation unit 303 determines whether or not the input timing required at the end of the second most recent period has been reached (step S808).

  For example, when the music reaches the point when the first chorus ends, the evaluation unit 303 obtains the average value of the results of the chorus part before the interlude (period A in FIG. 7), and uses the obtained value as the reproduction unit. 302 and the adjustment unit 304 are notified.

  Based on the notified average value of the grades, the playback unit 302 selects a voice to be played back immediately after the first nearest period from the voice candidate voices stored in the RAM 103 or the like (step S805). For example, the reproducing unit 302 selects the call A based on the results in the period A.

  Next, the adjustment unit 304 obtains the reproduction volume of the selected voice call based on the results of the first most recent period (step S806), and notifies the reproduction unit 302 of it.

  The reproduction unit 302 reproduces the voice A in the period of the interlude A at the notified volume (step S807).

  Next, the evaluation unit 303 determines whether or not the input timing obtained at the end of the second most recent period (periods C to E in FIG. 7) has been reached (step S808). If the input timing required at the end of the second most recent period has not been reached (step S808; No), the state of input by the player is continuously examined (step S801).

When the input timing calculated at the end of the second most recent period has been reached (step S808; Yes), for example, an average value of the results for the input of the second most recent period is obtained (step S809), and the value is calculated. Notify the adjustment unit 304. For example, when it is time to reproduce the applause C, the average of results in the period C in FIG. 7 is obtained and notified to the adjustment unit 304. Based on the received average value, for example, as shown in the first embodiment, the adjustment unit 304 obtains applause reproduction volume (step S810), and notifies the reproduction unit 302 of the obtained reproduction volume. The reproduction unit 302 reproduces the sound data of the applause C at the notified volume in the second most recent period, that is, the period C in FIG. 7 (step S811).
It should be noted that the above-mentioned applause volume adjustment and reproduction processing (steps S808 to S811) may be performed in parallel with the call volume adjustment and reproduction processing (steps S803 to S807).

  According to the present embodiment, the playback volume of the sub-audio whose playback timing is set according to the music can be adjusted according to the performance of the play, so the audience is making a call or applause according to the music Such effects can be given.

  In the present invention, if the play is continued successfully in the first and second evaluation periods and the first and second most recent periods, the volume is gradually increased according to the number of times that the success has been continued. Also good. For example, if the playback volume is set according to the equation shown in FIG. 9, if the player input is successful twice in the bar A of FIG. 5, the playback volume is set to “2” and continuously. If four times succeeds, the playback volume is set to “8”. In addition, the timing at which the first and second sub-voices are reproduced is not limited to immediately after the first and second evaluation periods or the first and second most recent periods. The applause may be reproduced.

  As described above, according to the present invention, in a game device that reproduces sound, a game device, a game control method, and the like that are suitable for creating a sense of realism according to the player's results are realized by a computer. A program can be provided.
