[Problems to be solved by the invention]
However, in the prior art, even if the operation in the battle scene of the player or the battle situation with the enemy character changes from moment to moment, the BGM does not change accordingly. For this reason, the game-specific interactivity is not reflected in the game music itself, and it has a monotonous atmosphere compared to the game play operation.
[0005]
Further, even if there is a change in BGM, since the tempo has only changed, it has been difficult to say that the entertainment is enhanced to give the player a sense of excitement.

FIG. 2 is a block diagram showing an electrical internal configuration of the video game system 10 of FIG. 1 embodiment. The video game machine 12 is provided with a central processing unit (hereinafter referred to as “CPU”) 36. The CPU 36 is also called a computer or a processor, and is responsible for overall control of the game machine. The CPU 36 or the computer functions as a game processor and is coupled to the memory controller 38 via a bus. The memory controller 38 mainly controls writing and reading of the main memory 40 coupled via the bus under the control of the CPU 36. The main memory 40 is used as a work area or a buffer area. A GPU (Graphics Processing Unit) 42 is coupled to the memory controller 38.
[0036]
The GPU 42 is configured by, for example, a single chip ASIC, receives a graphics command (graphics command) from the CPU 36 via the memory controller 38, and in accordance with the command, the geometry unit and the rendering unit included in the 3D (3D) ) Generate a game image. In other words, the geometry unit rotates, moves, and moves various characters and objects (consisting of a plurality of polygons. A polygon is a polygonal plane defined by at least three vertex coordinates). Perform coordinate calculation processing such as deformation. The rendering unit pastes (renders) a texture (texture image) to each polygon of various objects. Therefore, 3D image data to be displayed on the game screen is created by the GPU 42, and the image data is drawn (stored) in a frame buffer (not shown) provided in association with the GPU 42, and the pixel Is stored in a Z buffer (not shown). Note that data (primitives, polygons, textures, etc.) necessary for the GPU 42 to execute the drawing command is acquired from the main memory 40 by the GPU 42 via the memory controller 38.

Here, the frame buffer is a memory for drawing (accumulating) image data for one frame of the raster scan monitor 34, for example, and is rewritten frame by frame by the GPU. A video I / F 50 described later reads the frame buffer data via the memory controller 38, whereby a 3D game image is displayed on the screen of the monitor 34. The capacity of the frame buffer is a size corresponding to the number of pixels (pixels or dots) on the screen to be displayed. For example, it has the number of pixels (storage position or address) corresponding to the number of pixels of the display or monitor 34. The Z buffer has a storage capacity corresponding to the number of pixels (storage position or address) corresponding to the frame buffer × the number of bits of depth data per pixel, and the depth of dots corresponding to each storage position of the frame buffer. Information or depth data (Z value) is stored. Note that both the frame buffer and the Z buffer may be configured using part of the main memory 40.

[0039]
The DSP 44 performs audio processing tasks. The ARAM 46 is used to store sound waveform data (sound data) read from the disk 18. The DSP 44 receives an audio processing command from the CPU 36 via the memory controller 38, extracts necessary sound waveform data in accordance with the command, and mixes, for example, pitch modulation, mixing of audio data and effect data, and mixing with other tracks. Perform processing / mixing. The audio processing command is generated by sequentially reading and analyzing performance data (BGM data) written in the main memory 40 by executing the sound control program. The sound waveform data is read sequentially and processed by the DSP 44 to generate game audio content. The resulting content or audio output data is buffered in the main memory 40, for example, and then transferred to the audio I / F 54 for output as, for example, stereo sound at the speaker 34a. Therefore, the sound is output from the speaker 34a.
[0040]
Note that the generated audio data is not limited to 2ch stereo reproduction, and can of course be applied to surround reproduction or monaural reproduction such as 5.1ch, 6.1ch, 7.1ch.

[0042]
The controller I / F 48 is an interface for the controller 22, and provides an operation signal or data of the operation means 26 of the controller 22 to the CPU 36 through the memory controller 38.
[0043]
The video I / F 50 accesses the frame buffer, reads the image data created by the GPU 42, and supplies the image signal or image data (digital RGB pixel value) to the monitor 34 via the AV cable 32 (FIG. 1).
[0044]
The external memory I / F 52 links the memory card 30 (FIG. 1) inserted in the front surface of the game machine 12 to the memory controller 38. Thereby, the CPU 36 can write data to the memory card 30 or read data from the memory card 30 via the memory controller 38.
[0045]
The audio I / F 54 includes a D / A converter (not shown), receives audio data provided from a buffer through the memory controller 38 or an audio stream read from the optical disc 18, and monitors an audio signal (sound signal) corresponding thereto. 34 to the speaker 34a.
[0046]
In the case of stereo sound, at least one speaker 34a is provided on each of the left and right speakers. In the case of surround reproduction, for example, in addition to the speaker 34a of the monitor 34, five and one for bass (in the case of 7.1ch surround reproduction) may be provided via an AV amplifier or the like.
[0047]
The disk I / F 56 couples the disk drive 16 to the memory controller 38, and thus the CPU 36 controls the disk drive 16. Program data, object data, image data, performance data, and the like read from the optical disk 18 by the disk drive 16 are written into the main memory 40 under the control of the CPU 36.

[0062]
For example, as shown in FIG. 7A, when the player character 96 encounters the enemy character 98, the performance of the battle BGM is started. In this BGM for battle, the musical instrument sound (track) to be played is increased according to the distance between the player character 96 and the enemy character 98, and the tempo is increased when the remaining physical strength value of the player character 96 decreases. The atmosphere can be changed. Note that different songs may be played in the battle BGM depending on the type of enemy character (normal enemy, intermediate boss, etc.).
[0063]
By operating the operation means 26 of the controller 22, the player can apply various attacks to the enemy character 98 using, for example, a sword equipped with the player character 96. Also depending on the type of equipment item of the player character 96, the attack mode, etc., the BGM can change its atmosphere by switching the playing track.
[0064]
For example, the normal battle BGM data of this embodiment is the performance data for performance at all times. The track 1 is strings (Strings), the track 2 is Jet Flute, the track 3 is Horn, and the track 4 is Timpani is provided. Furthermore, as performance data for the close combat state, the track 5 is provided with percussion (Percussion), and the track 6 is provided with a trombone. Furthermore, the track 7 is provided with strings as performance data for the sword-equipped state, and the track 8 is provided with a pizzicato as performance data for the sword-unequipped state. The track 9 is provided with a baroque flute as performance data for the rotation cutting state. The BGM data includes, for example, all musical instruments (tutti) on track A, percussion on track B, trumpet and trombone on track C as total data (tutti).
[0065]
When the player character 96 and the enemy character 98 are in a predetermined relationship, that is, in this embodiment, when the attack of the player character 96 hits the enemy character 98, as shown in FIG. In addition to the BGM for battle, tutti data is played. As the total performance data, one that matches the hit situation of the player character's attack and the BGM chord at that time is selected, and is played at a predetermined timing in harmony with the beat and beat of the BGM.
[0066]
In this way, since tutti (accent melody) that matches the BGM chord progression and timing in real time can be added to the BGM, the BGM closely adheres to the BGM and has a more melodic accent according to the player's operation. Can express.
[0067]
FIG. 8 shows the game operation of the game system 10. When playing a game, when the optical disk 18 is set in the game machine 12 and the power is turned on as described above, the CPU 36 reads data from the optical disk 18 in the first step S1 of FIG. The data is stored (loaded) in the main memory 40 as shown in FIG. The CPU 36 executes processing according to these loaded programs. In the next step S3, the sound waveform data read from the optical disk 18 and once written in the main memory 40 by the CPU 36 is loaded into the ARAM 46 as shown in FIG.
[0068]
In step S5, the CPU 36 acquires an operation input signal from the controller 22, and executes the subsequent steps S7 to S17 in response to the operation signal. In step S7, the CPU 36 moves the player character according to the operation input signal. For example, when the game player operates the direction indicating means (for example, the cross key or the analog joystick) of the controller 22, the CPU 36 moves the player character in that direction in the game space in this step S7. For example, if an operation instruction means (for example, A button) is operated, in this step S7, the player character is caused to perform an attacking action using, for example, a sword.
[0069]
In the subsequent step S9, the CPU 36 executes an action process for a non-player object such as an enemy character or a stationary object. In step S11, drawing processing of the operated object is executed. As a result, a game image corresponding to the operation of the user player is displayed on the monitor 34.
[0070]
In subsequent step S13, the CPU 36 executes a sound control process for controlling the performance of the BGM and the overall performance data. The process of step S13 is shown in detail in FIG. 9, and the description of this process will be described later. In step S15, the CPU 36 executes another game process, and determines whether or not to end the game in the subsequent step S17. If “NO” in the step S17, that is, if the game is continued, the process returns to the step S5 to repeat the process. On the other hand, if “YES” in the step S17, that is, if the game is to be ended, a game end process (not shown) is performed and the process is ended.
[0071]
FIG. 9 shows the operation of the sound control process in step S13 of FIG. In step S21, the CPU 36 determines whether the enemy character is near the player character. The distance between the player character and the enemy character is calculated from each position data stored in a predetermined area of the main memory 40. If the distance between the two is smaller than the predetermined value, it is determined that the two are close to each other, that is, in a battle state.
[0072]
If "YES" in the step S21, it is determined whether or not the battle BGM is already being reproduced in a succeeding step S23. If “NO” in the step S23, that is, if the battle BGM has not been reproduced yet, the CPU 36 instructs the start of the performance of the battle BGM in a step S25. Thus, as described above, the performance data of the battle BGM is sequentially analyzed to generate an audio processing command (including waveform processing information). Then, the DSP 44 generates battle BGM audio data in accordance with this command, and then outputs the sound of this battle BGM from the speaker 34a.
[0073]
For example, before step S23, the type of enemy character may be determined and a BGM corresponding to the type of enemy may be selected.
[0074]
If “YES” in the step S23, or when the process of the step S25 is finished, the subsequent processes in the step S27 and subsequent steps are executed. The processing from step S27 to step S51 relates to various settings for BGM and tutti performance according to the progress of the game. That is, when the start of BGM performance is instructed in step S25, audio processing commands based on these settings are generated until the performance is stopped.
[0075]
In step S27, the CPU 36 executes a total performance (tutti) control process. By this tutti control process, the tutti data that matches the BGM chord is played at a predetermined timing. This tutti control process is shown in detail in FIG. 10, and the description of this process will be described later.
[0076]
Next, in step S29, the CPU 36 changes the BGM tempo in accordance with the physical strength value data of the main character (player character) read from the predetermined area 80 of the main memory 40. That is, the CPU 36 generates a BGM audio processing command reflecting the tempo changed based on the physical fitness value data, and gives this to the DSP 44. As a result, for example, the BGM is played at a faster tempo than the normal tempo as the hero's physical strength value data becomes smaller, so that the player can feel a sense of frustration. This change in tempo is also reflected in the performance of tutti data (step S69 in FIG. 10) described later.
[0077]
In step S31, it is determined whether the enemy is very close. That is, when the player character and the enemy character come close to each other and the distance between them becomes smaller than a predetermined value that is smaller than the distance at the time of determination of the battle state, it is determined that both are in the approaching state. If “NO” in the step S31, that is, if both are not in the approaching state, the CPU 36 turns off the approaching battle track in a step S33. On the other hand, if “YES” in the step S31, the close combat truck is turned on in a step S35. Thus, the CPU 36 generates a processing command including the performance information of the track when the track is turned on, and generates a processing command not including the performance information of the track when the track is turned off. In this way, the atmosphere of a song can be changed by switching on / off or switching the volume of a specific track according to the distance between the player character and the enemy character. For example, this close combat track includes percussion (percussion instruments), which can make the player fighting close combat more excited.
[0078]
When the process of step S33 or step S35 is completed, in the next step S37, the CPU 36 determines whether or not the player character is equipped with a sword. If “NO” in the step S37, that is, if the player character is not equipped with a sword, the CPU 36 turns off the sword-equipped track in a step S39 and returns to the step S21. On the other hand, if “YES” in the step S37, that is, if the player character is equipped with a sword, the CPU 36 turns on the sword equipped track in a step S41. Thus, the atmosphere of the song can be changed by switching on / off the specific track according to the equipment state of the player character.
[0079]
When the process of step S41 is completed, in the subsequent step S43, the CPU 36 determines whether or not the player character is turning the sword using the sword. If “NO” in the step S43, that is, if the player character is not rotating, the CPU 36 turns off the rotating cutting track in a step S45. On the other hand, if “YES” in the step S43, that is, if the player character is rotating and cutting, the rotating and cutting track is turned on in a step S47. In this way, the atmosphere of the song can be changed by switching on / off the specific track according to the attack form of the player character.
[0080]
When the process of step S45 or step S47 is completed, in the subsequent step S49, the CPU 36 determines whether or not the attack hits the enemy character. Whether or not the attack is hit is determined based on the player character's real-time position data, equipment item data, or attack form data stored in the player object data storage area 60, and the enemy stored in the non-player object data storage area 62. It is determined based on the real-time position data of the character. For example, when there is an attack when the distance between the two is smaller than a predetermined value set in relation to the equipment item, the attack mode, etc., it is determined as an attack hit. If “NO” in the step S49, that is, if the attack of the player character does not hit the enemy character, the process returns to the step S21.
[0081]
On the other hand, if “YES” in the step S49, that is, if the attack hits the enemy character, in a succeeding step S51, the CPU 36 sets a total control flag corresponding to the hit situation in the main memory 40. Set (write) in the area or buffer, and return to step S21. Here, the hit situation indicates a situation when the attack of the player character hits an enemy character, that is, for example, a normal hit, a weak hit, a strong hit, a third step of a three-step attack, a jump attack, and Indicates whether it was a special attack or not. Since the tutti control flag is set in accordance with such a hit situation, when the tutti data is played in the process of step S69 described later, different tutti data can be selected and played depending on the hit situation.
[0082]
If “NO” in the step S21, that is, if the distance between the player character and the enemy character is equal to or greater than a predetermined value and is not in a battle state or the enemy is defeated, the battle BGM is reproduced in a step S53. Judge whether inside. If “YES” in the step S53, the CPU 36 instructs the stop of the battle BGM in a step S55, ends the sound control process, and returns to the main flow of FIG.
[0083]
In this embodiment, the presence / absence of sword equipment is determined in step S37. However, in other embodiments, other equipment equipment may be determined and a track corresponding to the item may be selected. .
[0084]
Further, in step S43, it is determined whether or not it is a rotation slash, but in another embodiment, it is determined whether or not it is another attack mode (special attack) and a track corresponding to the attack mode is selected. You may do it.
[0085]
FIG. 10 shows the operation of the tutti control process in step S27 of FIG. In step S61, the CPU 36 determines whether or not the chord of the song (BGM) has changed. When the start of BGM is instructed in step S25 (FIG. 9), the chord progression data is sequentially read together with the performance data, so that it is sequentially judged whether or not the chord information has changed.
[0086]
If “YES” in the step S61, that is, if there is a change in the chord progression of the music, the chord information is set (stored) in a predetermined area of the main memory 40 in a step S63. The chord information indicates the chord at the time when the BGM is to be played. When the tutti is to be played, the chord information is read in step S69 described later.
[0087]
If “NO” in the step S61, or when the process of the step S63 is finished, in a step S65, the CPU 36 determines whether or not the music has progressed by an eighth note. That is, it is determined whether or not the position to be played (processed) is coincident with the timing of progressing by an eighth note from the previous determination time, in other words, whether the performance data for the eighth note has been processed from the previous determination time. to decide. In this way, the timing for starting the tutti performance is measured at regular intervals (in this example, in eighth note units) from the beginning of the song. Accordingly, tutti is not played at a timing unrelated to the beat of BGM, so that the player does not feel uncomfortable. If “NO” in the step S65, that is, if the predetermined timing is not reached, the process returns to the step S61.
[0088]
This timing is not limited to this and can be changed as appropriate. In another embodiment, the timing may be, for example, a triplet head and a third (shuffle pattern). Also, this timing may be different for each BGM. For example, the above-mentioned triplet shuffle pattern may be adopted in the case of an intermediate boss battle BGM.
[0089]
On the other hand, if “YES” in the step S65, that is, if it is a predetermined timing, in a succeeding step S67, the CPU 36 determines whether or not the tutti control flag stands in a predetermined area or buffer of the main memory 40. If “NO” in the step S67, that is, if the tutti control flag is not set (the attack is not hit), the process returns to the step S61.
[0090]
On the other hand, if “YES” in the step S67, that is, if the tuti control flag is set, in a step S69, the CPU 36 is based on the tuti control flag information (including information indicating the hit situation) and the code information. Then, the tutti data of the track to be played is selected, and the start of the performance of the tuti data is instructed. Therefore, as described above, the performance data of the selected tutti is read out and analyzed together with the performance data of the BGM, and an audio processing command for playing the BGM and tutti is generated and given to the DSP 44. . In accordance with this command, the DSP 44 generates (BGM + tutti) audio data, and then the BGM sound to which this tuti has been added is output from the speaker 34a (FIG. 7B). In this way, when an attack is hit, tutti data corresponding to the player character's attack hit situation and adapted to the BGM code is played.
[0091]
As described above, when the tempo is changed in the process of step S29, the CPU 36 generates a process command based on the changed tempo, so that the tempo of tutti can also be changed in the same manner as BGM. it can. Therefore, there is no deviation between BGM and accent.
[0092]
In step S71, the CPU 36 turns off the tutti control flag written in the predetermined area or buffer of the main memory 40, that is, writes the data with the tuti control flag turned off in the predetermined area, and then in step S61. Return to.
[0093]
According to this embodiment, since tutti (accent melody) matched and harmonized in real time with the BGM chord progression and timing can be added to the BGM, it is more closely attached to the BGM than a known technique that simply produces a sound effect. And more melodic accents. Therefore, since the BGM changes interactively and melodicly according to the game play situation of the player, it is possible to give the player a sense of excitement and to enhance entertainment.
