Description

  The present invention relates to a game program and a game system with improved sound generation processing.

  There are many video games in which a player character fights against a plurality of enemy characters. In such a game, when a player character enters a place where many enemy characters hang out, a sound (hereinafter referred to as a “gaya sound”) is produced that the place is rumbling by many enemy characters. ) To produce the atmosphere.

  It has also been proposed to extract and reproduce sound data of other characters existing within a certain range from the player character (see, for example, Patent Document 1). However, with this method, it has not been possible to produce an atmosphere in which many enemy characters are nearby and noisy.

  Therefore, the Gaya sound generation process in the conventional game determines a specific area (for example, a room or a cave) set in advance as a Gaya sound generation area, and when there are a predetermined number or more of enemy characters in this area. When the player character enters this area, a process of generating a noise is performed.

  Here, with reference to FIG. 2 to FIG. 5, control (gay noise generation control) on which conditions to generate the above-mentioned noise is described. In the present invention, a “gay sound” that is a noise generated by a plurality of enemy characters EC is generated when a predetermined number or more of enemy characters EC exist in a predetermined area (gay sound determination area) based on the player character PC. Let

  FIG. 2 is a diagram for briefly explaining the noise generation control according to the noise determination area. In the gay sound generation control of the present invention, as shown in FIG. 2A, a range within a predetermined distance D from the player character PC is defined as a gay sound determination area E in the game space. In FIG. 2, the boundary of the Gaya sound determination area E is shown by a circle. However, in the actual game space, the Gaya sound determination area E is formed in a three-dimensional manner, and the boundary is spherical.

  As shown in the sound selection table of FIG. 2B, when there are three to five enemy characters EC in the gay sound determination area E, the sound 1 is selected as the gay sound, and this sound 1 is selected by the DSP 35. Produces. When there are 6 to 10 enemy characters EC in the Gaya sound determination area E, the sound 2 is selected as the Gaya sound, and the DSP 35 generates this sound 2. Further, when 11 or more enemy characters EC exist in the Gaya sound determination area E, the sound 3 is selected as the Gaya sound, and the DSP 35 generates this sound 3. Sound 2 is louder than Sound 1 and Sound 3 is louder than Sound 2.

  In the example of FIG. 2, even if there is an enemy character in the gay sound determination area E, no gay sound (sound) is generated if there are two or less characters. As described above, even if there is an enemy character in the gay sound determination area E, the gay sound may not be generated when the number is less than a predetermined number.

  In the example of FIG. 2A, since there are six enemy characters EC in the Gaya sound determination area E, the sound 2 is selected. In this case, the CPU 30 transfers the waveform data of the sound 2 to the DSP 35 and causes the DPS 35 to generate a sound signal of the sound 2. Thereby, the sound of sound 2 is emitted from the speaker of the TV 2, and an atmosphere in which about 6 to 10 enemy characters EC exist near the player character PC is produced.

  In the case where a gay sound is generated, it is arbitrary in which position in the game space the sound image of the gay sound is localized or generated without any localization. In order to localize to any position, it is preferable to localize to the position of any enemy character EC existing in the Gaya sound determination area E. The position of the enemy character EC to be localized is arbitrary, but, for example, the enemy character EC closest to the player character PC may be selected as the localization position, and one is randomly selected from the positions of the plurality of enemy characters EC. May be selected as the localization position.

  The player character PC moves by a user operation or the like. Since the gay sound determination area E is an area centered on the player character PC, the gay sound determination area E moves as the player character PC moves as shown in FIG. As a result, the number of enemy characters EC existing in the Gaya sound determination area E is increased or decreased by the movement of the enemy character EC itself, and also changes by the movement of the player character PC.

  As described above, whether or not a gay sound is generated and what kind of sound is generated as a gay sound is determined based on the position of the player character PC, and the gay sound determination area moves as the player character PC moves. By determining according to E and the number of enemy characters EC existing in the gay sound determination area E, control of the gay sound corresponding to the actual number of enemy characters EC near the player character PC is possible. become.

  As described above, the gay sound generation control of the present invention has been briefly described. However, in this embodiment, the gay sound generation control is performed by a more complicated method. Hereinafter, the generation control of the gay sound in this embodiment will be described.

  FIG. 3 is an explanatory diagram of the gay sound determination areas E1 and E2 in the present embodiment. A range within the first distance D1 from the player character PC is defined as a first gay sound determination area E1. Further, a range farther than the first distance D1 and within the second distance D2 is defined as a second gay sound determination area E2. The first distance D1 and the second distance D2 are distances in the game space GS, and are set to 15 m and 30 m, for example. As described in the explanation of FIG. 2, the boundary between the first gay sound determination area E1 and the second gay sound determination area E2 is indicated by a circle, but in an actual game space, it is spherical.

  FIG. 4 is selected corresponding to each of a plurality of conditions C11 to C23 indicating how many enemy characters EC exist in the first Gaya sound judgment area E1 and the second Gaya sound judgment area E2 shown in FIG. It is a figure which shows the sound selection table which shows the waveform data GS1-4 of random sound, and random range R0, R1. The random range is a numerical value indicating the time range (range) of the repetition interval of the waveform data. That is, when the same waveform data is repeated at the same interval (fixed interval), a monotonous and cheap sound is produced. Therefore, the repetition interval is randomized to change the noise.

  FIG. 5 is a diagram showing a sound data group included in the game program 50. As shown in this figure, the game program 50 includes a player character sound data group 510, an enemy character sound data group 520, an environmental sound data group 530, and a Gaya sound data group 540. . Each sound data group is composed of a plurality of waveform data, and optimum waveform data is selected according to the scene of the game, and a game sound is generated based on the waveform data. In this example, the Gaya sound data group 540 includes four waveform data GS1 to GS4.

  Each of the waveform data GS1 to GS4 is short waveform data of about several seconds. In the game, the waveform data is repeatedly read out at random intervals, thereby generating a continuous noise sound. The range of this random interval is determined by the range of random ranges R1 and R2. In this embodiment, the random range R1 is 2 to 5 seconds, and the random range R0 is 4 to 7 seconds. The greater the number of bodies and the closer the noise detection area, the shorter the time range may be selected to increase the noise. However, if the lengths of the waveform data GS1 to GS4 are not the same, the random range may be changed depending on the length of the selected waveform data.

  When 3 to 5 enemy characters EC exist in the first Gaya sound determination area E1 (condition C11), the waveform data GS1 is selected as the Gaya sound, and the sound based on the waveform data GS1 is in the range of the random range R0. Are generated at intervals determined within When there are 6 to 10 enemy characters EC in the first gay sound determination area E1 (condition C12), the waveform data GS1 is selected as the gay sound, and the sound based on the waveform data GS1 is in the range of the random range R1. Are generated at intervals determined within When 11 or more enemy characters EC exist in the first Gaya sound determination area E1 (condition C13), the waveform data GS2 is selected as the Gaya sound, and the sound based on the waveform data GS2 is in the range of the random range R1. Are generated at intervals determined within

  In addition, when there are three to five enemy characters EC in the second gay sound determination area E2 farther than the first gay sound determination area E1 (condition C21), the waveform data GS3 is selected as the gay sound. The voice based on the waveform data GS3 is generated at intervals determined within the range of the random range R0. When there are 6 to 10 enemy characters EC in the second Gaya sound determination area E2 (condition C22), the waveform data GS3 is selected as the Gaya sound, and the sound based on the waveform data GS3 is in the range of the random range R1. Are generated at intervals determined within When 11 or more enemy characters EC exist in the second Gaya sound determination area E2 (condition C23), the waveform data GS4 is selected as the Gaya sound, and the sound based on the waveform data GS4 falls within the range of the random range R1. Are generated at intervals determined within

  FIG. 6 is a functional block diagram of the game apparatus 100 realized by cooperation between the game machine 1 and the game program 50. The game device 100 includes a game space control unit 110, a player character control unit 111, an enemy character control unit 112, an environmental sound control unit 120, a player character sound control unit 121, an enemy character sound control unit 122, a Gaya sound control unit 123, and a pronunciation. A processing unit 130 and a game image generation unit 131 are included.

  The game space control unit 110 creates a game space that is a virtual three-dimensional space, and controls changes in weather, passage of time / season, and the like. The environmental sound control unit 120 selects an environmental sound as appropriate according to the generated game space, weather, time, season, and the like, and sends an instruction to the sound generation processing unit 130 to generate the environmental sound.

  The player character control unit 111 generates a player character PC whose activity is controlled by a user operation and activates it in the game space. The player character sound control unit 121 appropriately selects a sound (waveform data) related to the player character PC such as a walking sound, a weapon sound, and a voice according to the action of the player character PC, and generates a sound so as to generate the sound. An instruction is sent to the unit 130.

  The enemy character control unit 112 generates a plurality of enemy characters EC and activates them in the game space. The enemy character sound control unit 122 appropriately selects a sound related to the enemy character EC such as a walking sound, a cry, and an attack sound according to the action of the enemy character EC, and instructs the pronunciation processing unit 130 to generate the sound. send.

  The gay sound control unit 123 includes an area setting unit 124, a body number counting unit 125, and a generation control unit 126. The area setting unit 124 acquires the current position of the player character PC from the player character control unit 111, and sets the first gay sound determination area E1 and the second gay sound determination area E2 based on the acquired current position. The body count unit 125 obtains the current positions of the plurality of enemy characters EC from the enemy character control unit 112, and the inside of the first gay sound determination area E1 and the second gay sound determination area E2 set by the area setting unit 124. The number of enemy characters EC existing in The count value of the body count unit 125 is input to the generation control unit 126. The generation control unit 126 determines which of the conditions C11 to C23 shown in the sound selection table in FIG. 4 is the enemy character EC in each of the gay sound determination areas E1 and E2 input from the body counting unit 125 ( Which condition is satisfied) is determined, and sound using waveform data corresponding to the satisfied condition is generated at an appropriate timing (the timing of the repetition interval determined in the range of the random range R0 / 1). An instruction is sent to the sound generation processing unit 130 as described above.

  The sound generation processing unit 130 includes the DSP 35 of FIG. 1 and the sound data groups 510, 520, 530, and 540 shown in FIG. 5, and includes the environmental sound control unit 120, the player character sound control unit 121, the enemy character sound control unit 122, and the Gaya. When generation of sound is instructed from the sound control unit 123, a sound signal is generated using the instructed waveform data. The sound generation processing unit 130 includes various filter functions, converts the generated audio signal into a plurality of channels of stereo, and performs volume adjustment, sound quality adjustment, delay adjustment, and the like for each channel. Thereby, the volume, sound quality, localization, etc. are adjusted.

  The game image composition unit 131 is a two-dimensional image obtained by photographing the game space GS, the player character PC, and the enemy character EC generated by the game space control unit 110, the player character control unit 111, and the enemy character control unit 112 from predetermined positions. Generate an image.

  Here, with reference to FIG. 7, the sound generation control unit 126 executes. The sound generation control operation of the Gaya sound will be described. The sound generation control operation is executed for each frame (1/60 second) for each of the conditions C11 to C23 in the sound selection table. In FIG. 7, processing for the condition C11 will be described as an example. The frame period is not limited to 1/60 seconds. For example, it may be 1/30 second. Moreover, the execution cycle of this process may not be a frame unit.

  In the operation for each frame, first, whether or not the condition C11, that is, the condition that three to five enemy characters EC are present in the first Gaya sound determination area E1 is satisfied in this frame (is satisfied). Judgment is made (S1). If the condition C11 is not satisfied (NO in S11), the flag F11 is reset (S20) and the operation is terminated. If the condition C11 is satisfied (YES in S1), it is determined whether the flag F11 is already set (S2). If the flag F11 is not set (NO in S2), the flag F11 is set (S3), and 1 second is set in the call timer T11 that measures the time until the sound generation processing unit 130 is instructed to generate sound. (S4).

  If the flag F11 is set (YES in S2), it is determined whether the call timer T11 has timed up, that is, the call timing is reached (S5). If it is not the call timing (NO in S5), the operation is terminated as it is. When the call timing is reached (YES in S5), the localization position of the gay sound is determined (S6), and the sound generation processing unit 130 is instructed to generate the gay sound (waveform data GS1) at this localization position ( S7). Then, an interval until the next call timing (gay sound generation timing) is randomly determined in the time range of the random range R0 (S8) and set in the call timer T11 (S9). The operation ends after the above processing.

  In S6, the localization position of the gay sound may be set to the position of any enemy character EC existing in the first gay sound determination area E1 that is the determination target area. For example, the position of the enemy character EC closest to the player character PC. Further, the time until the next call timing in S8 is randomly determined in units of 1/100 within the selected random range R0 (4 seconds to 7 seconds).

  The above has been described by taking the condition C11 as an example, but the same processing operation is executed for other conditions. When a plurality of conditions (for example, C11 and C22) are satisfied at the same time, the sound generation control operation for each condition may be executed as it is, but a plurality of noises may not be generated at the same time. For example, the establishment of one condition may be invalidated and the sound generation control operation may be executed when the condition is not satisfied. The sound generation control operation is executed when both conditions are satisfied, but one S7 process is canceled so that no sound is generated. May be. In this case, a condition close to the player character PC, that is, a condition established in the first gay sound determination area E1 may be prioritized. In addition, a condition that is established (continued) first may be prioritized.

  Also, a plurality of waveform data (such as GS1) may be designated in each column of the sound selection table of FIG. In this case, the reproduction order of the plurality of waveform data may be any, for example, random.

  When multiple types of enemy characters EC appear in the game, the Gaya sound control described with reference to FIGS. 2 to 7 may be executed as all enemy characters EC without distinguishing the types, and only one type of enemy character EC is used. May be performed.

  Further, when multiple types of enemy characters EC appear in the game, the gay sound control may be executed for each of the multiple types of enemy characters EC. In this case, the gay sound control for each enemy character EC may be executed independently. However, even if a plurality of conditions are satisfied, cancellation of satisfaction of the conditions or cancellation of the sound generation instruction is performed so that a plurality of gay sounds are not generated. You may make it perform.

  Further, in the above embodiment, the Gaya sound determination area E is an area within a certain distance D with the player character PC as the center, but the Gaya sound determination area E is not limited to this and is hollow as shown by E2 in FIG. (Doughnut) or distorted shape may be used. For example, it may be longer (or shorter) in a specific direction, such as being longer in the direction in which the player character PC is facing. Further, the shape may be changed depending on the position or place of the player character PC. For example, when the player character PC is near an obstacle, the area is narrowed in the direction of the obstacle. It is also possible to reduce the area in a space where sound is released and to increase the area in a reverberating space such as a cave.

  In this embodiment, the enemy character EC, that is, the opponent who fights the player character PC is an object that causes the occurrence of the gay sound, but the object that causes the generation of the gay sound is not limited to the enemy character EC. For example, it may be another vehicle competing together.
