By executing the game program, the control unit 56 causes the communication unit 561, the game space generation unit 562, the player character motion control unit 563, the enemy character motion control unit 564, the guidance determination unit 565, and the voice output control unit (sound). (Corresponding to output control means) 566.

Of these, the game space generation means 562 and the player character motion control means 563 mainly serve as a game progression means. The game progress means reads out data such as a game space object and texture included in the game data from the storage unit 55 and generates game image information. By processing the game image information by the graphic processing unit 52, the processed game image is displayed on the display 61.

The communication unit 561 has a function of communicating with the server device 2 via the network interface 51. The communication unit 561 transmits the account information and the download request information for new game data based on the user's operation to the server device 2. The communication unit 561 receives new game data and the like sent from the server device 2.

The game space generation unit 562 generates a three-dimensional game space, that is, a virtual space in which the player character PC1 moves by the user operating the game controller 63.

The player character motion control means 563 arranges the player character PC1 in the game space. The player character motion control means 563 moves the player character PC1 in the game space based on an operation performed by the user via the game controller 63.

The enemy character motion control means 564 arranges the enemy characters EM1 and EM2 according to the progress and quest of the game in the game space. The enemy character motion control means 564 causes the enemy characters EM1 and EM2 to perform a motion set in advance to some extent according to the progress status of the game and the quest. In addition, the enemy character motion control means 564 causes the enemy characters EM1 and EM2 to perform a motion according to the motion of the player character PC1.

The guidance determining means 565 determines whether or not the player character PC1 is in a guidance state guiding the enemy characters EM1 and EM2 when the player character PC1 in battle with the enemy characters EM1 and EM2 is moving. A guidance determination process is performed according to a predetermined guidance determination condition. As shown in FIG. 3, the guided state is a state in which the enemy characters EM1 and EM2 follow the moving player character PC1, that is, a state in which the enemy characters EM1 and EM2 are moving following the movement of the player character PC1. Say

In FIG. 3, the movement paths of the player character PC1 and the enemy character EM1 are represented by a plurality of connected arrows. One arrow corresponds to one frame of a plurality of frame images forming the game image, and the length of each arrow indicates the amount of movement of each of the player character PC1 and the enemy character EM1 per frame.

The guidance determination conditions will be described in detail in <Guide determination processing>.

The audio output control unit 566 sequentially reads audio data from the storage unit 55 in accordance with the progress of the game, the contents of the quest, the actions of the player character PC1 and the enemy characters EM1, EM2, and the like, and via the audio processing unit 53. Audio is output from the speaker 62.

The voice includes voices of the characters PC1, EM1, and EM2, sound effects such as footsteps and roaring sounds, and music unique to the enemy characters EM1 and EM2.

In particular, the audio output control means 566 performs music selection processing and volume change processing. The music selection process is a process of selecting a music in progress of the game according to various situations and outputting the selected music from the speaker 62. The volume change process is a process of changing the volume of the music output from the speaker 62 according to various conditions.

The music selection process will be described in detail in <Music selection process>, and the volume change process will be described in <Volume change process>.

<About guidance judgment processing>
The guidance determination process performed by the guidance determination unit 565 will be described in detail with reference to FIGS.

The player character PC1 at the time of battle has a unique condition that the battle is advantageous for the player character PC1 based on various settings such as items to be used (for example, weapons) and the habit of the user's operation. The guide state shown in FIG. 3 is a state used when the enemy characters EM1 and EM2 are intentionally guided to a place where the battle is advantageous for the player character PC1 in consideration of such a condition.

Similar to FIG. 3, FIG. 4 illustrates a state where the player character PC1 and the enemy character EM1 are in battle. As shown in FIG. 4, the predetermined guidance determination conditions used to determine whether or not the vehicle is in the guidance state include the following three conditions.
(First condition) Each of the moving distance of the player character PC1 and the moving distance of the enemy character EM1 is equal to or more than a predetermined distance.
(Second condition) The enemy character EM1 moves from an arbitrary battle area (corresponding to the first area, CA3 in FIG. 4) to a moving area (corresponding to the second area, MA5 in FIG. 4) connected to the area CA3. thing.
(Third condition) The angle θ formed by the movement vectors indicating the movement direction and the movement distance of the player character PC1 and the enemy character EM1 is within a predetermined range.

In determining the first condition, as shown in FIG. 5, the guidance determining unit 565 determines a predetermined number of frames before (e.g., 8 frames before) the current trajectory of the player character PC1 and the enemy trajectory EM1. Vector approximation to (movement vector). The guidance determination unit 565 calculates the length of each of the movement vectors as the sum of the movement amounts.

That is, although the direction and the amount of movement of each of the characters PC1 and EM1 are different for each frame, the guidance determining unit 565 does not calculate the total value of the amount of movement in each frame, but rather from the present to the past. The moving distance is calculated with one unit as a unit that is traced back a predetermined number of frames. Therefore, if the characters PC1 and EM1 are moved so as to return to the place where they were in the past, the moving distance is calculated to be short due to the influence of this.

The guidance determining unit 565 repeats the above-described moving distance calculation processing for each frame. The guidance determining unit 565 determines that the first condition is satisfied when the calculation result is equal to or more than the predetermined distance, and determines that the first condition is not satisfied when the calculation result is not equal to or more than the predetermined distance.

In the guided state, the enemy character EM1 moves by chasing the moving player character PC1 and thus the moving distance tends to be longer. Therefore, if the moving distance of the enemy character EM1 is shorter than the predetermined distance, it can be said that the player character PC1 is not guiding the enemy character EM1. Therefore, the first condition is included as one condition for determining the guiding state.

The "predetermined distance" is set in advance to a value that is common to all the areas CA1 to CA8 and MA1 to MA11 and is longer than the width of the areas. The “predetermined number of frames” is preset to an appropriate value.

Again in FIG. 4, the second condition is determined to be satisfied when the enemy character EM1 in battle moves from the battle area CA3 to the moving area MA5 adjacent to the enemy character EM1 even once. When the enemy character EM1 remains in one battle area CA3 (that is, the area is not changed), the guidance determining unit 565 determines that the second condition is not satisfied.

As described above, the enemy character EM1 has the property that it does not leave the battle area CA3, which is the battle area, during the battle, but if it is guided by the player character PC1, it is in the battle area. Exit CA3. Therefore, the second condition is included as one condition for determining the guiding state.

In determining the third condition, the guidance determining means 565 causes the start point of the movement vector of each of the characters PC1 and EM1 used in the first condition (that is, each character PC1 at a time point a predetermined number of frames before the current position). , EM1 position), one of the movement vectors is translated. In FIG. 4, as an example, the movement vector of the enemy character EM1 is translated.

The guidance determination means 565 determines that the third condition is satisfied when the angle θ formed by these vectors is within a predetermined range. The guidance determination unit 565 determines that the third condition is not satisfied when the angle θ is not within the predetermined range.

For example, when a plurality of player characters cooperate to battle one enemy character EM1, it is possible that the player characters move in different directions all at once. In this case, since there is only one enemy character EM1, not all player characters can be in the guiding state. On the other hand, the angle θ formed by the movement vector of the player character not chased by the enemy character EM1 and the movement vector of the enemy character EM1 is out of the predetermined range. In order to utilize this, the third condition is included as one condition for determining the guidance state.

The guidance determining means 565 sequentially determines (for each frame) while the player character PC1 is moving whether or not all the first to third conditions are satisfied. The guidance determining unit 565 determines that the vehicle is in the guidance state when all of the first to third conditions are satisfied, and when none of the first to third conditions is satisfied, it is not in the guidance state. judge.

In addition, the guidance determining unit 565 resets the result of the above determination of the guidance state in response to the first predetermined trigger. An example of the first predetermined trigger is when the player character PC1 takes a predetermined motion state in the guidance state. In the predetermined operation state, the player character PC1 attacks the enemy characters EM1 and EM2 (including the guiding enemy character EM1) staying in the battle areas CA1 to CA8, and the player characters from the enemy characters EM1 and EM2. At least one of the state where the character PC1 is attacked is included.

<About music selection processing>
The sound output control means 566 performs a music selection process of selecting a music caused by the enemy characters EM1 and EM2 and outputting the same from the speaker 62 during the game in which at least the player character PC1 and the enemy characters EM1 and EM2 are operating.

-Type of music-
The songs that are candidates for selection in the song selection process include “battle songs”, “moving songs”, “guide songs”, and “lost songs”.

The “battle song” is a song that is output while the enemy characters EM1 and EM2 and the player character PC1 are fighting.

Here, the enemy characters EM1 and EM2 include a plurality of types of enemy characters such as a small fish character, a boss character on the stage SG, and a main enemy character in the game, and they are ranked according to the content of the game. Has been applied. In response to this, the "battle song" includes "battle song of small fish character", "battle song of boss character on stage SG", and "battle song of major enemy character".

The "battle song" also has a "battle song" unique to the stage.

The “moving song” is a song output while the enemy characters EM1 and EM2 are moving in the areas CA1 to CA8 and MA1 to MA11.

The “guidance song” is a song that is output while the enemy character EM1, EM2 is being guided by the moving player character PC1 (during the above-described guiding state).

The “missing song” is a song output when the enemy characters EM1 and EM2 lose sight of the player character PC1 who was fighting.

-Selection and switching of music-
The audio output control unit 566 selects a music piece to be output from the above-mentioned music pieces according to the types of the enemy characters EM1 and EM2 against which the player character PC1 is hostile and the types of operation states.

For example, when the operation state of the enemy character EM1 which is the boss character on the stage SG is in a state of fighting with the player character PC1, the voice output control means 566 selects “the battle song of the boss character on the stage SG”. To do. When the enemy character EM1 is guided by the player character PC1, the voice output control means 566 selects "guide music".

In selecting the music, the audio output control unit 566 further selects the music based on the priority of the music. For example, it is assumed that the “small fish character”, the “boss character on the stage SG”, and the “main enemy character” stay in the same area. On the other hand, the priority of "battle song" is predetermined in the order of ""battle song of main enemy character">"battle song of boss character on stage SG>>"battle song of small fish character"". The output control unit 566 determines a battle tune according to the types of the enemy characters EM1 and EM2 in battle with the player character PC1 and the priority.

Further, when the arbitrary music (first music) is being output from the speaker 62, the audio output control unit 566 outputs the music different from the arbitrary music (the first music) in response to the second predetermined trigger.
2nd song). The second predetermined trigger is that the type of motion state of the enemy characters EM1 and EM2 has changed, the predetermined motion state that the player character PC1 has already described (a state in which the enemy character is attacked, and a state in which an attack is applied). ) Is taken.

It should be noted that the enemy character movement control means 564 moves the enemy characters EM1 and EM2 to a predetermined place such as a nest of the enemy character EM1 and EM2 when the total value of damages received by the battle exceeds a reference value. Then let them go to "sleep state". In this case, the audio output control unit 566 does not select the music and stops outputting the music.

<About volume change processing>
While the music is being output, the voice output control means 566 performs a voice changing process that changes the volume of the music according to the distance from the player character PC1 to the player character PC1 and the enemy characters EM1 and EM2 in battle.

During the battle between the player character PC1 and the enemy characters EM1 and EM2, the music resulting from the enemy characters EM1 and EM2 is output from the speaker 62 by the music selection process. During the battle, since the player character PC1 and the enemy characters EM1 and EM2 are moving with each other, the distance between the player character PC1 and the enemy characters EM1 and EM2 on the horizontal plane and the distance on the vertical plane change from time to time.

Therefore, the audio output control unit 566 increases or decreases the volume of the music according to the distance on the horizontal plane and the distance on the vertical plane. Specifically, the sound output control unit 566 increases the volume as the distance between the player character PC1 and the enemy characters EM1 and EM2 is smaller (closer), and increases the distance between the player character PC1 and the enemy characters EM1 and EM2 ( The farther away, the lower the volume.

When the player character PC1 or the enemy characters EM1 and EM2 make area movements, the characters PC1, EM1 and EM2 do not stay in the same battle areas CA1 to CA8. By that time, the distance between the player character PC1 and the enemy characters EM1 and EM2 gradually increases (distances), so the audio output control unit 566 gradually lowers the volume of the music. The voice output control means 566 stops the output of the music when a predetermined time elapses after the characters PC1, EM1, and EM2 do not stay in the same battle areas CA1 to CA8.

Further, in the above music selection process, the audio output control unit 566 switches the output music from any first music to another second music while gradually lowering the volume of the first music before switching, The volume of the second music after switching is gradually increased (crossfade).

<Specific example of music selection processing and volume change processing>
Hereinafter, specific examples (patterns 1 to 5) of the above-described music selection processing and volume change processing will be described with reference to FIGS.

The operation states adopted by the respective characters PC1, EM1, and EM2 described below are controlled by the player character movement control means 563 and the enemy character movement control means 564.

-Pattern 1-
As shown in FIG. 6A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. Since the enemy character that is hostile to the player character PC1 is "EM1" and the operation state of the enemy character EM1 is "battle", the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62. .. The voice output control means 566 changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1.

Thereafter, as shown in FIG. 6B, it is assumed that the enemy character EM1 is moving in the moving area MA1 due to the battle area change. In this case, since the operation state of the enemy character EM1 is “moving”, the voice output control unit 566 selects the moving music 1 and switches the output music from the battle music 1 to the moving music 1 by crossfade. .. The voice output control unit 566 changes the volume of the moving music 1 according to the distance between the characters PC1 and EM1.

Note that in FIG. 6B, the distance between the characters PC1 and EM1 is larger than that in FIG. 6A.

Thereafter, as shown in FIG. 6C, the enemy character EM1 reaches the battle area CA2, but the player character PC1 remains in the battle area CA1. The operation state of the enemy character EM1 in this case is "combat standby". Since the distance between the characters PC1 and EM1 is larger than that in FIG. 6B, the voice output control unit 566 further reduces the volume of the moving music piece 1 to be smaller than that in FIG. 6B.

When the state of “waiting for battle” is maintained for 10 seconds, the audio output control means 566 mutes the volume of the moving music 1 (stops output).

-Pattern 2-
As shown in FIG. 7A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the audio output control unit 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 7B, it is assumed that the player character PC1 is moving in the moving area MA1 due to the battle area change. On the other hand, since the operation state of the enemy character EM1 is still "battle", the voice output control means 566 continues the above control of FIG. 7(a).

Note that, in FIG. 7B, since the player character PC1 is away from the enemy character EM1, the volume of the battle song 1 is lower than that in FIG. 7A.

Thereafter, as shown in FIG. 7C, the player character PC1 has reached the battle area CA2, but the enemy character EM1 continues to remain in the battle area CA1 in the "battle" motion state. The distance between the characters PC1 and EM1 is larger than that in FIG. 7B. Therefore, the sound output control means 566 further reduces the volume of the battle song 1 to a level lower than that shown in FIG.

When the state in which the characters PC1 and EM1 stay in different battle areas CA1 and CA2 is maintained for 10 seconds, the voice output control unit 566 mutes the volume of the battle song 1 (stops output).

-Pattern 3-
As shown in FIG. 8A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 8B, it is assumed that the enemy character EM1 is moving in the moving area MA1 due to the battle area change. In this case, the operation state of the enemy character EM1 is "move", as in FIG. 6(b). Therefore, the voice output control means 566 changes the output music piece from the battle music piece 1 to the moving music piece 1 by crossfade, and changes the volume of the moving music piece 1 according to the distance between the characters PC1 and EM1.

Note that in FIG. 8B, the distance between the characters PC1 and EM1 is larger than that in the case of FIG. 8A.

Thereafter, as shown in FIG. 8C, the enemy character EM1 continues to move within the battle area CA2, but another enemy character EM2 appears in the battle area CA1 where the player character PC1 is present. When the enemy character EM2 attacks the player character PC1 and enters a battle state, for example, the voice output control means 566 selects and switches the music in accordance with the priority of the music corresponding to the enemy characters EM1 and EM2. To do.

Specifically, it is assumed that the priority is set in advance to "battle song 2 of enemy character EM2>moving song 1 of enemy character EM1". The voice output control unit 566 switches the output music piece from the moving music piece 1 to the battle music piece 2 caused by the enemy character EM2 by crossfade.

Further, the voice output control means 566 changes the volume of the battle song 2 according to the distance between the characters PC1 and EM2. In FIG. 8C, since the distance between the characters PC1 and EM2 is relatively small, the volume of the battle song 2 is higher than that in FIG. 8B.

-Pattern 4-
As shown in FIG. 9A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

Further, in FIG. 9A, the enemy character EM2 is staying in another battle area CA2, but the operation state is the “combat standby state”. Therefore, the audio output control unit 566 does not select the music caused by the enemy character EM2.

After that, as shown in FIG. 9B, it is assumed that the player character PC1 is moving in the moving area MA1 due to the battle area change. On the other hand, since the operation state of the enemy character EM1 is still "battle", the voice output control means 566 continues the above control of FIG. 9(a).

In FIG. 9B, since the player character PC1 is moving away from the enemy character EM1, the volume of the battle song 1 is lower than that in FIG. 9A.

After that, as shown in FIG. 9C, the enemy character EM1 is still in a battle state in the battle area CA1, but another enemy character EM2 in the battle area CA2 arrives at the battle area CA2. And the battle state.

It is assumed that the priority of the music is set in advance to "battle music 1 of enemy character EM1>battle music 2 of enemy character EM2". Then, the voice output control means 566 can control the output music piece to be the battle music piece 1 and change the volume of the battle music piece 1 according to the operation states of the enemy characters EM1 and EM2 and the priority. Conceivable.

However, the opponent with which the player character PC1 is actually fighting is the enemy character EM2 in the same fighting area CA2. When the priority is emphasized, the battle song 1 accompanying the enemy character EM1 remains output unless a predetermined time (for example, 10 seconds) elapses after the operation state of the enemy character EM1 transits to the battle standby state. Become. In this case, a mismatch between the combat opponent and the music being output occurs for at least a predetermined time, and the user feels strange.

Therefore, as shown in FIG. 9C, for example, when the player character PC1 attacks the enemy character EM2 for the first time in the battle area CA2 (takes a predetermined operation state), the voice output control means 566 outputs. The song to be played is switched from battle song 1 to battle song 2. Specifically, the voice output control means 566 mutes the battle song 1 with the start of the attack as a trigger (stops output), and outputs the battle song 2 with a volume corresponding to the distance between the characters PC1 and EM2. Let it start.

That is, when the priority is between battle songs, the voice output control unit 566 gives priority to the battle song 2 of the enemy character EM2 actually fighting with the player character PC1 over the priority.

It should be noted that the player character PC1 attacks regardless of the type of weapon used, with a relatively short distance from the enemy character EM2. Therefore, FIG. 9(c) shows that the battle song 2 has begun to be output at a relatively high volume.

-Pattern 5-
As shown in FIG. 10A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 10B, it is assumed that the player character PC1 starts to guide the enemy character EM1. The guide state is determined by the guide determining unit 565 based on the guide determination condition, as described in <Guide determination process>. When it is determined that the music is in the guided state, the voice output control means 566 selects the guided music 1 and switches the output music from the battle music 1 to the guided music 1 by crossfade. The voice output control unit 566 changes the volume of the guide song 1 according to the distance between the characters PC1 and EM1.

After that, as shown in FIG. 10C, it is assumed that both characters PC1 and EM1 arrive at the battle area CA2 and are in battle again.

However, as described above, whether or not the vehicle is in the guiding state is determined by whether or not the guiding determination condition is satisfied. Therefore, the determination result “the guiding state” is maintained until the guiding state is not satisfied. Then, no matter how much battle is performed between the two characters PC1 and EM1, the guiding state is maintained until the anger of the enemy character EM1 is subsided. This is because the angry enemy character EM1 moves following the player character PC1. Therefore, the guidance music 1 corresponding to the determination result “guidance state” is continuously output until the guidance determination condition is not satisfied even if the battle is actually performed, and the user feels uncomfortable.

Therefore, as shown in FIG. 10C, when the player character PC1 attacks the enemy character EM1 for the first time in the battle area CA2 (takes a predetermined motion state), the guidance determining unit 565 determines that the determination result is “ The "guidance state" is reset, and the voice output control means 566 switches the music piece to be output from the guidance music piece 1 to the battle music piece 1. Specifically, the voice output control unit 566 mutes the guidance song 1 with the start of the attack as a trigger (output is stopped), and outputs the battle song 1 with a volume corresponding to the distance between the characters PC1 and EM2. Let it start.

<Flow of a series of processing in the game device 5>
With reference to FIG. 11, a flow of a series of processes including the above-described processes in the game device 5 in progress of the game will be described.

During the progress of the game, the voice output control means 566 selects a music piece according to the operation state of the enemy characters EM1 and EM2 and outputs the music piece from the speaker 62 (step St1). At this time, the audio output control unit 566 changes the volume of the music piece according to the distance between the player character PC1 and the enemy characters EM1 and EM2 (step St2).

The guidance determination unit 565 determines whether all the guidance determination conditions (first condition, second condition, and third condition) are satisfied in each frame of the game image (step St3).

When all the guidance determination conditions are satisfied (Yes in step St3), the guidance determination means 565 determines that the player character PC1 is in a guidance state in which it guides the enemy characters EM1 and EM2 (step St4). The voice output control unit 566 switches the music to be output from the music related to step St1 to the guide music (step St5), and sets the volume of the guide music according to the distance between the characters PC1, EM1, and EM2. It is changed (step St6).

When the player character PC1 attacks the enemy characters EM1 and EM2 that were the guiding opponents in the guided state (Yes in step St7), the audio output control unit 566 outputs the output music until then. The guide music that has been played is switched to the battle music of the enemy characters EM1 and EM2 (step St8), and the volume of the battle music is changed according to the distance between the two characters PC1, EM1, and EM2 (step St9). ).

Further, although the enemy characters EM1 and EM2 have not been attacked (No in step St7), the guidance determining unit 565 determines that at least one guidance determination condition is not satisfied (step St10). Yes). In this case, the audio output control unit 566 switches the output music from the guide music that has been output until then to a music according to the operation state of the enemy characters EM1 and EM2 that are currently hostile (step St11), In addition, the volume of the music piece is changed according to the distance between the characters PC1, EM1, and EM2 (step St12).

In step St10, if all of the guidance determination conditions are still satisfied (No in step St10), the guidance determination means 565 and the voice output control means 566 repeat the operations after step St7.

In step St3, when all of the guidance determination conditions are not satisfied (No in step St3), the guidance determination means 565 determines that the guidance state is not established.

When the battle opponent (enemy characters EM1 and EM2) of the player character PC1 is changed to another opponent (enemy character different from step St1) different from the opponent up to then (Yes in step St13), the voice output control means 566. Based on the priority of the music, it is determined whether the music prioritized with the priority and the music corresponding to the changed battle opponent are the same (step St14).

When the music prioritized by the priority and the music corresponding to the changed battle opponent are the same (Yes in step St14), the audio output control unit 566 switches the music output according to the priority (step). St15). The audio output control unit 566 changes the volume of the music piece in accordance with the distance between the player character PC1 and the changed battle opponent (step St16).

When the music prioritized by the priority and the music corresponding to the changed combat opponent are not the same (No in Step St14), the audio output control unit 566 corresponds the output music to the changed combat opponent. It switches to the music to be performed (step St17). The voice output control unit 566 changes the volume of the music piece according to the distance between the player character PC1 and the changed battle opponent (step St18).

In step St13, if the battle opponent of the player character PC1 has not been changed (No in step St13), the states of steps St1 and St2 are inherited.

When the operation state of the battle opponent (enemy characters EM1 and EM2) of the player character PC1 thereafter transits to the battle standby state and a predetermined time has elapsed (Yes in step St19), the audio output control unit 566 has been output until then. The volume of the selected song is muted (step St20). When the operation state of the battle opponent does not transition to the battle standby state, or when the transition to the battle standby state transitions to another operation state within a predetermined time (No in step St19), step St3 and subsequent steps The process of is repeated.

To summarize the above, the game program of the present embodiment causes the control unit 56 (computer) of the game apparatus 5 to move the player character PC1 in the game space based on the user's operation, and player character motion control means 563, The enemy character motion control means 564 that moves the enemy characters EM1 and EM2 that oppose the player character PC1 in the game space, and when the player character PC1 moves in the game space, the enemy follows the movement of the player character PC1. The guidance determination means 565 determines whether or not the characters EM1 and EM2 are in a moving guidance state.

<Effect of the invention>
According to the game program of the present embodiment, the guidance determining unit 565 determines whether or not the enemy characters EM1 and EM2 are in a guidance state in which the enemy characters EM1 and EM2 are moving following the movement of the player character PC1. As a result, the range of the game can be widened by utilizing the determination result, such as performing an effect according to the determination result. Therefore, the user can play a more entertaining game.

Specifically, the guidance determination unit 565 determines that the vehicle is in the guidance state when all the guidance determination conditions including the first condition, the second condition, and the third condition are satisfied.

The first condition is that the moving distance of each of the characters PC1, EM1, and EM2 is a predetermined distance or more. This is because the moving distance of each of the characters PC1, EM1, EM2 naturally increases in the guided state.

The second condition is that the enemy characters EM1 and EM2 have moved from an arbitrary battle area (first area) to a movement area (second area). In this game, since the enemy characters EM1 and EM2 in battle are required to stay in the battle areas CA1 to CA8, the possibility that they are in a guided state emerges if the second condition is satisfied. Because.

The third condition is that the angle formed by the movement vectors of the characters PC1, EM1, and EM2 is within a predetermined range. When a plurality of player characters cooperate to battle one enemy character EM1, EM2, each player character may move in different directions. In that case, if there is a player character that satisfies the third condition, the possibility that the character is guiding an enemy character emerges.

In addition, when the player character PC1 takes the predetermined motion state, the guidance determining unit 565 resets the determination result that the player character PC1 is in the guidance state. The predetermined operation state includes at least one of a state in which the player character PC1 has attacked the enemy characters EM1 and EM2, and a state in which the player character PC1 has been attacked by the enemy characters EM1 and EM2. As a result, it is possible to switch to an effect different from the effect in the guidance state at an appropriate timing, and the game becomes more interesting.

In particular, as one of the above-mentioned effects, the voice output control means 566 outputs the guide music 1 (first music) according to the guide state. As a result, the music piece suitable for the guide state is output from the speaker 62, so that the user can feel a sense of presence and a feeling of dynamism, and can play a more entertaining game.

When the guidance determination unit 566 resets the determination result that the guidance state is the guidance state, the voice output control unit 566 outputs the music to be output from the guidance music (first music) to another music (second music such as battle music). Songs). As a result, since music corresponding to various states is output from the speaker 62, the game becomes more entertaining.

In particular, the game space of this game is a space in which battle areas CA1 to CA8 and movement areas MA1 to MA11 are seamlessly connected. Since it is seamless, there is no load screen when the player character PC1 moves in the areas CA1 to CA8 and MA1 to MA11, and it can be said that the timing for changing the music is poor. In such a game space, in the present embodiment, the guide song is switched to another song at the timing when the player character PC1 takes a predetermined operation state. As a result, it is possible to provide a realistic and dynamic sound that does not cause the user to feel discomfort.

The storage unit 55 includes an HDD, SSD, RAM, ROM, and the like. The storage unit 55 can store the game program and the game data downloaded from the server device 2. In the present embodiment, the game data stored in the storage unit 55 includes the above-mentioned game sound data.

The control unit 56 is composed of a microcomputer including a CPU and a semiconductor memory, and controls the operation of the own device 5.

<Functional Configuration of Control Unit 56 in Game Device 5>
By executing the game program, the control unit 56 causes the communication unit 561, the game space generation unit 562, the player character motion control unit 563, the enemy character motion control unit 564, the guidance determination unit 565, and the voice output control unit ( output). (Corresponding to means ) 566.

Of these, the game space generation means 562 and the player character motion control means 563 mainly serve as a game progression means. The game progress means reads out data such as a game space object and texture included in the game data from the storage unit 55 and generates game image information. By processing the game image information by the graphic processing unit 52, the processed game image is displayed on the display 61.

The communication unit 561 has a function of communicating with the server device 2 via the network interface 51. The communication unit 561 transmits the account information and the download request information for new game data based on the user's operation to the server device 2. The communication unit 561 receives new game data and the like sent from the server device 2.

The game space generation unit 562 generates a three-dimensional game space, that is, a virtual space in which the player character PC1 moves by the user operating the game controller 63.

The player character motion control means 563 arranges the player character PC1 in the game space. The player character motion control means 563 moves the player character PC1 in the game space based on an operation performed by the user via the game controller 63.

The enemy character motion control means 564 arranges the enemy characters EM1 and EM2 according to the progress and quest of the game in the game space. The enemy character motion control means 564 causes the enemy characters EM1 and EM2 to perform a motion set in advance to some extent according to the progress status of the game and the quest. In addition, the enemy character motion control means 564 causes the enemy characters EM1 and EM2 to perform a motion according to the motion of the player character PC1.

The guidance determining means 565 determines whether or not the player character PC1 is in a guidance state guiding the enemy characters EM1 and EM2 when the player character PC1 in battle with the enemy characters EM1 and EM2 is moving. A guidance determination process is performed according to a predetermined guidance determination condition. As shown in FIG. 3, the guided state is a state in which the enemy characters EM1 and EM2 follow the moving player character PC1, that is, a state in which the enemy characters EM1 and EM2 are moving following the movement of the player character PC1. Say

In FIG. 3, the movement paths of the player character PC1 and the enemy character EM1 are represented by a plurality of connected arrows. One arrow corresponds to one frame of a plurality of frame images forming the game image, and the length of each arrow indicates the amount of movement of each of the player character PC1 and the enemy character EM1 per frame.

The guidance determination conditions will be described in detail in <Guide determination processing>.

The audio output control unit 566 sequentially reads audio data from the storage unit 55 according to the progress of the game, the contents of the quest, the actions of the player character PC1 and the enemy characters EM1 and EM2, and the like, and outputs the audio data via the audio processing unit 53. Audio is output from the speaker 62.

The voice includes voices of the characters PC1, EM1, and EM2, sound effects such as footsteps and roaring sounds, and music unique to the enemy characters EM1 and EM2.

In particular, the audio output control means 566 performs music selection processing and volume change processing. The music selection process is a process of selecting a music in progress of the game according to various situations and outputting the selected music from the speaker 62. The volume change process is a process of changing the volume of the music output from the speaker 62 according to various conditions.

The music selection process will be described in detail in <Music selection process>, and the volume change process will be described in <Volume change process>.

<About guidance judgment processing>
The guidance determination process performed by the guidance determination unit 565 will be described in detail with reference to FIGS.

The player character PC1 at the time of battle has a unique condition that the battle is advantageous for the player character PC1 based on various settings such as items to be used (for example, weapons) and the habit of the user's operation. The guide state shown in FIG. 3 is a state used when the enemy characters EM1 and EM2 are intentionally guided to a place where the battle is advantageous for the player character PC1 in consideration of such a condition.

Similar to FIG. 3, FIG. 4 illustrates a state where the player character PC1 and the enemy character EM1 are in battle. As shown in FIG. 4, the predetermined guidance determination conditions used to determine whether or not the vehicle is in the guidance state include the following three conditions.
(First condition) Each of the moving distance of the player character PC1 and the moving distance of the enemy character EM1 is equal to or more than a predetermined distance.
(Second condition) The enemy character EM1 moves from an arbitrary battle area (corresponding to the first area, CA3 in FIG. 4) to a moving area (corresponding to the second area, MA5 in FIG. 4) connected to the area CA3. thing.
(Third condition) The angle θ formed by the movement vectors indicating the movement direction and the movement distance of the player character PC1 and the enemy character EM1 is within a predetermined range.

In determining the first condition, as shown in FIG. 5, the guidance determining unit 565 determines a predetermined number of frames before (e.g., 8 frames before) the current trajectory of the player character PC1 and the enemy trajectory EM1. Vector approximation to (movement vector). The guidance determination unit 565 calculates the length of each of the movement vectors as the sum of the movement amounts.

That is, although the direction and the amount of movement of each of the characters PC1 and EM1 are different for each frame, the guidance determining unit 565 does not calculate the total value of the amount of movement in each frame, but rather from the present to the past. The moving distance is calculated with one unit as a unit that is traced back a predetermined number of frames. Therefore, if the characters PC1 and EM1 are moved so as to return to the place where they were in the past, the moving distance is calculated to be short due to the influence of this.

The guidance determining unit 565 repeats the above-described moving distance calculation processing for each frame. The guidance determining unit 565 determines that the first condition is satisfied when the calculation result is equal to or more than the predetermined distance, and determines that the first condition is not satisfied when the calculation result is not equal to or more than the predetermined distance.

In the guided state, the enemy character EM1 moves by chasing the moving player character PC1 and thus the moving distance tends to be longer. Therefore, if the movement distance of the enemy character EM1 is shorter than the predetermined distance, it can be said that the player character PC1 is not guiding the enemy character EM1. Therefore, the first condition is included as one condition for determining the guiding state.

The "predetermined distance" is set in advance to a value that is common to all the areas CA1 to CA8 and MA1 to MA11 and is longer than the width of the areas. The “predetermined number of frames” is preset to an appropriate value.

Again in FIG. 4, the second condition is determined to be satisfied when the enemy character EM1 in battle moves from the battle area CA3 to the moving area MA5 adjacent to the enemy character EM1 even once. When the enemy character EM1 remains in one battle area CA3 (that is, the area is not changed), the guidance determining unit 565 determines that the second condition is not satisfied.

As described above, the enemy character EM1 has the property that it does not leave the battle area CA3, which is the battle area, during the battle, but if it is guided by the player character PC1, it is in the battle area. Exit CA3. Therefore, the second condition is included as one condition for determining the guiding state.

In determining the third condition, the guidance determining means 565 causes the start point of the movement vector of each of the characters PC1 and EM1 used in the first condition (that is, each character PC1 at a time point a predetermined number of frames before the current position). , EM1 position), one of the movement vectors is translated. In FIG. 4, as an example, the movement vector of the enemy character EM1 is translated.

The guidance determination means 565 determines that the third condition is satisfied when the angle θ formed by these vectors is within a predetermined range. The guidance determination unit 565 determines that the third condition is not satisfied when the angle θ is not within the predetermined range.

For example, when a plurality of player characters cooperate to battle one enemy character EM1, it is possible that the player characters move in different directions all at once. In this case, since there is only one enemy character EM1, not all player characters can be in the guiding state. On the other hand, the angle θ formed by the movement vector of the player character not chased by the enemy character EM1 and the movement vector of the enemy character EM1 is out of the predetermined range. In order to utilize this, the third condition is included as one condition for determining the guidance state.

The guidance determining means 565 sequentially determines (for each frame) while the player character PC1 is moving whether or not all the first to third conditions are satisfied. The guidance determining unit 565 determines that the vehicle is in the guidance state when all of the first to third conditions are satisfied, and when none of the first to third conditions is satisfied, it is not in the guidance state. judge.

In addition, the guidance determining unit 565 resets the result of the above determination of the guidance state in response to the first predetermined trigger. An example of the first predetermined trigger is when the player character PC1 takes a predetermined motion state in the guidance state. In the predetermined operation state, the player character PC1 attacks the enemy characters EM1 and EM2 (including the guiding enemy character EM1) staying in the battle areas CA1 to CA8, and the player characters from the enemy characters EM1 and EM2. At least one of the state where the character PC1 is attacked is included.

<About music selection processing>
The sound output control means 566 performs a music selection process of selecting a music caused by the enemy characters EM1 and EM2 and outputting the same from the speaker 62 during the game in which at least the player character PC1 and the enemy characters EM1 and EM2 are operating.

-Type of music-
The songs that are candidates for selection in the song selection process include “battle songs”, “moving songs”, “guide songs”, and “lost songs”.

The “battle song” is a song that is output while the enemy characters EM1 and EM2 and the player character PC1 are fighting.

Here, the enemy characters EM1 and EM2 include a plurality of types of enemy characters such as a small fish character, a boss character on the stage SG, and a main enemy character in the game, and they are ranked according to the content of the game. Has been applied. In response to this, the "battle song" includes "battle song of small fish character", "battle song of boss character on stage SG", and "battle song of major enemy character".

The "battle song" also has a "battle song" unique to the stage.

The “moving song” is a song output while the enemy characters EM1 and EM2 are moving in the areas CA1 to CA8 and MA1 to MA11.

The “guidance song” is a song that is output while the enemy character EM1, EM2 is being guided by the moving player character PC1 (during the above-described guiding state).

The “missing song” is a song output when the enemy characters EM1 and EM2 lose sight of the player character PC1 who was fighting.

-Selection and switching of music-
The audio output control unit 566 selects a music piece to be output from the above-mentioned music pieces according to the types of the enemy characters EM1 and EM2 against which the player character PC1 is hostile and the types of operation states.

For example, when the operation state of the enemy character EM1 which is the boss character on the stage SG is in a state of fighting with the player character PC1, the voice output control means 566 selects “the battle song of the boss character on the stage SG”. To do. When the enemy character EM1 is guided by the player character PC1, the voice output control means 566 selects "guide music".

In selecting the music, the audio output control unit 566 further selects the music based on the priority of the music. For example, it is assumed that the “small fish character”, the “boss character on the stage SG”, and the “main enemy character” stay in the same area. On the other hand, the priority of "battle song" is predetermined in the order of ""battle song of main enemy character">"battle song of boss character on stage SG>>"battle song of small fish character"". The output control unit 566 determines a battle tune according to the types of the enemy characters EM1 and EM2 in battle with the player character PC1 and the priority.

Further, when the arbitrary music (first music) is being output from the speaker 62, the audio output control unit 566 responds to the second predetermined trigger to output the music different from the arbitrary music ( 2nd song). The second predetermined trigger is that the type of the motion state of the enemy characters EM1 and EM2 has changed, the predetermined motion state that the player character PC1 has already described (a state in which the enemy character is attacked, and a state in which the enemy character is attacked). ) Is taken.

It should be noted that the enemy character movement control means 564 moves the enemy characters EM1 and EM2 to a predetermined place such as a nest of the enemy character EM1 and EM2 when the total value of damages received by the battle exceeds a reference value. Then let them go to "sleep state". In this case, the audio output control unit 566 does not select the music and stops outputting the music.

<About volume change processing>
While the music is being output, the voice output control means 566 performs a voice changing process that changes the volume of the music according to the distance between the player character PC1 and the enemy character EM1, EM2 in battle with the player character PC1.

During the battle between the player character PC1 and the enemy characters EM1 and EM2, the music resulting from the enemy characters EM1 and EM2 is output from the speaker 62 by the music selection process. During the battle, since the player character PC1 and the enemy characters EM1 and EM2 are moving with each other, the distance between the player character PC1 and the enemy characters EM1 and EM2 on the horizontal plane and the distance on the vertical plane change from time to time.

Therefore, the audio output control unit 566 increases or decreases the volume of the music according to the distance on the horizontal plane and the distance on the vertical plane. Specifically, the sound output control unit 566 increases the volume as the distance between the player character PC1 and the enemy characters EM1 and EM2 is smaller (closer), and increases the distance between the player character PC1 and the enemy characters EM1 and EM2 ( The farther away, the lower the volume.

When the player character PC1 or the enemy characters EM1 and EM2 make area movements, the characters PC1, EM1 and EM2 do not stay in the same battle areas CA1 to CA8. By that time, the distance between the player character PC1 and the enemy characters EM1 and EM2 gradually increases (distances), so the audio output control unit 566 gradually lowers the volume of the music. The voice output control means 566 stops the output of the music when a predetermined time elapses after the characters PC1, EM1, and EM2 do not stay in the same battle areas CA1 to CA8.

Further, in the above music selection process, the audio output control unit 566 switches the output music from any first music to another second music while gradually lowering the volume of the first music before switching, The volume of the second music after switching is gradually increased (crossfade).

<Specific example of music selection processing and volume change processing>
Hereinafter, specific examples (patterns 1 to 5) of the above-described music selection processing and volume change processing will be described with reference to FIGS.

The operation states adopted by the respective characters PC1, EM1, and EM2 described below are controlled by the player character movement control means 563 and the enemy character movement control means 564.

-Pattern 1-
As shown in FIG. 6A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. Since the enemy character that is hostile to the player character PC1 is "EM1" and the operation state of the enemy character EM1 is "battle", the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62. .. The voice output control means 566 changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1.

Thereafter, as shown in FIG. 6B, it is assumed that the enemy character EM1 is moving in the moving area MA1 due to the battle area change. In this case, since the operation state of the enemy character EM1 is “moving”, the voice output control unit 566 selects the moving music 1 and switches the output music from the battle music 1 to the moving music 1 by crossfade. .. The voice output control unit 566 changes the volume of the moving music 1 according to the distance between the characters PC1 and EM1.

Note that in FIG. 6B, the distance between the characters PC1 and EM1 is larger than that in FIG. 6A.

Thereafter, as shown in FIG. 6C, the enemy character EM1 reaches the battle area CA2, but the player character PC1 remains in the battle area CA1. The operation state of the enemy character EM1 in this case is "combat standby". Since the distance between the characters PC1 and EM1 is larger than that in FIG. 6B, the voice output control unit 566 further reduces the volume of the moving music piece 1 to be smaller than that in FIG. 6B.

When the state of “waiting for battle” is maintained for 10 seconds, the audio output control means 566 mutes the volume of the moving music 1 (stops output).

-Pattern 2-
As shown in FIG. 7A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 7B, it is assumed that the player character PC1 is moving in the moving area MA1 due to the battle area change. On the other hand, since the operation state of the enemy character EM1 is still "battle", the voice output control means 566 continues the above control of FIG. 7(a).

Note that, in FIG. 7B, since the player character PC1 is away from the enemy character EM1, the volume of the battle song 1 is lower than that in FIG. 7A.

Thereafter, as shown in FIG. 7C, the player character PC1 has reached the battle area CA2, but the enemy character EM1 continues to remain in the battle area CA1 in the "battle" motion state. The distance between the characters PC1 and EM1 is larger than that in FIG. 7B. Therefore, the sound output control means 566 further reduces the volume of the battle song 1 to a level lower than that shown in FIG.

When the state in which the characters PC1 and EM1 stay in different battle areas CA1 and CA2 is maintained for 10 seconds, the voice output control unit 566 mutes the volume of the battle song 1 (stops output).

-Pattern 3-
As shown in FIG. 8A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 8B, it is assumed that the enemy character EM1 is moving in the moving area MA1 due to the battle area change. In this case, the operation state of the enemy character EM1 is "move", as in FIG. 6(b). Therefore, the voice output control means 566 changes the output music piece from the battle music piece 1 to the moving music piece 1 by crossfade, and changes the volume of the moving music piece 1 according to the distance between the characters PC1 and EM1.

Note that in FIG. 8B, the distance between the characters PC1 and EM1 is larger than that in the case of FIG. 8A.

Thereafter, as shown in FIG. 8C, the enemy character EM1 continues to move within the battle area CA2, but another enemy character EM2 appears in the battle area CA1 where the player character PC1 is present. When the enemy character EM2 attacks the player character PC1 and enters a battle state, for example, the voice output control means 566 selects and switches the music in accordance with the priority of the music corresponding to the enemy characters EM1 and EM2. To do.

Specifically, it is assumed that the priority is set in advance to "battle song 2 of enemy character EM2>moving song 1 of enemy character EM1". The voice output control unit 566 switches the output music piece from the moving music piece 1 to the battle music piece 2 caused by the enemy character EM2 by crossfade.

Further, the voice output control means 566 changes the volume of the battle song 2 according to the distance between the characters PC1 and EM2. In FIG. 8C, since the distance between the characters PC1 and EM2 is relatively small, the volume of the battle song 2 is higher than that in FIG. 8B.

-Pattern 4-
As shown in FIG. 9A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

Further, in FIG. 9A, the enemy character EM2 is staying in another battle area CA2, but the operation state is the “combat standby state”. Therefore, the audio output control unit 566 does not select the music caused by the enemy character EM2.

After that, as shown in FIG. 9B, it is assumed that the player character PC1 is moving in the moving area MA1 due to the battle area change. On the other hand, since the operation state of the enemy character EM1 is still "battle", the voice output control means 566 continues the above control of FIG. 9(a).

In FIG. 9B, since the player character PC1 is moving away from the enemy character EM1, the volume of the battle song 1 is lower than that in FIG. 9A.

After that, as shown in FIG. 9C, the enemy character EM1 is still in a battle state in the battle area CA1, but another enemy character EM2 in the battle area CA2 arrives at the battle area CA2. And the battle state.

It is assumed that the priority of the music is preset to "battle music 1 of enemy character EM1>battle music 2 of enemy character EM2". Then, the voice output control unit 566 can perform control to change the volume of the battle song 1 by setting the output song as the battle song 1 in accordance with the operation states of the enemy characters EM1 and EM2 and the priority. Conceivable.

However, the opponent with which the player character PC1 is actually fighting is the enemy character EM2 in the same fighting area CA2. When the priority is emphasized, the battle song 1 accompanying the enemy character EM1 remains output unless a predetermined time (for example, 10 seconds) elapses after the operation state of the enemy character EM1 transits to the battle standby state. Become. In this case, a mismatch between the combat opponent and the music being output occurs for at least a predetermined time, and the user feels strange.

Therefore, as shown in FIG. 9C, for example, when the player character PC1 attacks the enemy character EM2 for the first time in the battle area CA2 (takes a predetermined operation state), the voice output control means 566 outputs. The song to be played is switched from battle song 1 to battle song 2. Specifically, the voice output control means 566 mutes the battle song 1 with the start of the attack as a trigger (stops output), and outputs the battle song 2 with a volume corresponding to the distance between the characters PC1 and EM2. Let it start.

That is, when the priority is between battle songs, the voice output control unit 566 gives priority to the battle song 2 of the enemy character EM2 actually fighting with the player character PC1 over the priority.

It should be noted that the player character PC1 attacks regardless of the type of weapon used, with a relatively short distance from the enemy character EM2. Therefore, FIG. 9(c) shows that the battle song 2 has begun to be output at a relatively high volume.

-Pattern 5-
As shown in FIG. 10A, it is assumed that the player character PC1 and the enemy character EM1 are fighting in the battle area CA1. In this case, as in the case of FIG. 6A, the voice output control means 566 selects the battle song 1 and outputs it from the speaker 62, and changes the volume of the battle song 1 according to the distance between the characters PC1 and EM1. Let

After that, as shown in FIG. 10B, it is assumed that the player character PC1 starts to guide the enemy character EM1. The guide state is determined by the guide determining unit 565 based on the guide determination condition, as described in <Guide determination process>. When it is determined that the music is in the guided state, the voice output control means 566 selects the guided music 1 and switches the output music from the battle music 1 to the guided music 1 by crossfade. The voice output control unit 566 changes the volume of the guide song 1 according to the distance between the characters PC1 and EM1.

After that, as shown in FIG. 10C, it is assumed that both characters PC1 and EM1 arrive at the battle area CA2 and are in battle again.

However, as described above, whether or not the vehicle is in the guiding state is determined by whether or not the guiding determination condition is satisfied. Therefore, the determination result “the guiding state” is maintained until the guiding state is not satisfied. Then, no matter how much battle is performed between the two characters PC1 and EM1, the guiding state is maintained until the anger of the enemy character EM1 is subsided. This is because the angry enemy character EM1 moves following the player character PC1. Therefore, the guidance music 1 corresponding to the determination result “guidance state” is continuously output until the guidance determination condition is not satisfied even if the battle is actually performed, and the user feels uncomfortable.

Therefore, as shown in FIG. 10C, when the player character PC1 attacks the enemy character EM1 for the first time in the battle area CA2 (takes a predetermined motion state), the guidance determining unit 565 determines that the determination result is “ The "guidance state" is reset, and the voice output control means 566 switches the music piece to be output from the guidance music piece 1 to the battle music piece 1. Specifically, the voice output control unit 566 mutes the guidance song 1 with the start of the attack as a trigger (output is stopped), and outputs the battle song 1 with a volume corresponding to the distance between the characters PC1 and EM2. Let it start.

<Flow of a series of processing in the game device 5>
With reference to FIG. 11, a flow of a series of processes including the above-described processes in the game device 5 in progress of the game will be described.

During the progress of the game, the voice output control means 566 selects a music piece according to the operation state of the enemy characters EM1 and EM2 and outputs the music piece from the speaker 62 (step St1). At this time, the audio output control unit 566 changes the volume of the music piece according to the distance between the player character PC1 and the enemy characters EM1 and EM2 (step St2).

The guidance determination unit 565 determines whether all the guidance determination conditions (first condition, second condition, and third condition) are satisfied in each frame of the game image (step St3).

When all the guidance determination conditions are satisfied (Yes in step St3), the guidance determination means 565 determines that the player character PC1 is in a guidance state in which it guides the enemy characters EM1 and EM2 (step St4). The voice output control unit 566 switches the music to be output from the music related to step St1 to the guide music (step St5), and sets the volume of the guide music according to the distance between the characters PC1, EM1, and EM2. It is changed (step St6).

When the player character PC1 attacks the enemy characters EM1 and EM2 that were the guiding opponents in the guided state (Yes in step St7), the audio output control unit 566 outputs the output music until then. The guide music that has been played is switched to the battle music of the enemy characters EM1 and EM2 (step St8), and the volume of the battle music is changed according to the distance between the two characters PC1, EM1, and EM2 (step St9). ).

Further, although the enemy characters EM1 and EM2 have not been attacked (No in step St7), the guidance determining unit 565 determines that at least one guidance determination condition is not satisfied (step St10). Yes). In this case, the audio output control unit 566 switches the output music from the guide music that has been output until then to a music according to the operation state of the enemy characters EM1 and EM2 that are currently hostile (step St11), In addition, the volume of the music piece is changed according to the distance between the characters PC1, EM1, and EM2 (step St12).

In step St10, if all of the guidance determination conditions are still satisfied (No in step St10), the guidance determination means 565 and the voice output control means 566 repeat the operations after step St7.

In step St3, when all of the guidance determination conditions are not satisfied (No in step St3), the guidance determination means 565 determines that the guidance state is not established.

When the battle opponent (enemy characters EM1 and EM2) of the player character PC1 is changed to another opponent (enemy character different from step St1) different from the opponent until then (Yes in step St13), the voice output control means 566. Based on the priority of the music, it is determined whether the music prioritized with the priority and the music corresponding to the changed battle opponent are the same (step St14).

When the music prioritized by the priority and the music corresponding to the changed battle opponent are the same (Yes in step St14), the audio output control unit 566 switches the music output according to the priority (step). St15). The audio output control unit 566 changes the volume of the music piece in accordance with the distance between the player character PC1 and the changed battle opponent (step St16).

It switches to the music to be performed (step St17). The voice output control unit 566 changes the volume of the music piece according to the distance between the player character PC1 and the changed battle opponent (step St18).

In step St13, if the battle opponent of the player character PC1 has not been changed (No in step St13), the states of steps St1 and St2 are inherited.

When the operation state of the battle opponent (enemy characters EM1 and EM2) of the player character PC1 thereafter transits to the battle standby state and a predetermined time has elapsed (Yes in step St19), the audio output control unit 566 has been output until then. The volume of the selected song is muted (step St20). When the operation state of the battle opponent does not transition to the battle standby state, or when the transition to the battle standby state transitions to another operation state within a predetermined time (No in step St19), step St3 and subsequent steps The process of is repeated.

To summarize the above, the game program of the present embodiment causes the control unit 56 (computer) of the game apparatus 5 to move the player character PC1 in the game space based on the user's operation, and player character motion control means 563, The enemy character motion control means 564 that moves the enemy characters EM1 and EM2 that oppose the player character PC1 in the game space, and when the player character PC1 moves in the game space, the enemy follows the movement of the player character PC1. The guidance determination means 565 determines whether or not the characters EM1 and EM2 are in a moving guidance state.

<Effect of the invention>
According to the game program of the present embodiment, the guidance determining unit 565 determines whether or not the enemy characters EM1 and EM2 are in a guidance state in which the enemy characters EM1 and EM2 are moving following the movement of the player character PC1. As a result, the range of the game can be widened by utilizing the determination result, such as performing an effect according to the determination result. Therefore, the user can play a more entertaining game.

Specifically, the guidance determination unit 565 determines that the vehicle is in the guidance state when all the guidance determination conditions including the first condition, the second condition, and the third condition are satisfied.

The first condition is that the moving distance of each of the characters PC1, EM1, and EM2 is a predetermined distance or more. This is because the moving distance of each of the characters PC1, EM1, EM2 naturally increases in the guided state.

The second condition is that the enemy characters EM1 and EM2 have moved from an arbitrary battle area (first area) to a movement area (second area). In this game, the enemy characters EM1 and EM2 in battle are required to remain in the battle areas CA1 to CA8. Therefore, if the second condition is satisfied, there is a possibility that the enemy characters are in a guided state. Because.

The third condition is that the angle formed by the movement vectors of the characters PC1, EM1, and EM2 is within a predetermined range. When a plurality of player characters cooperate to battle one enemy character EM1, EM2, each player character may move in different directions. In that case, if there is a player character that satisfies the third condition, the possibility that the character is guiding an enemy character emerges.

In addition, when the player character PC1 takes the predetermined motion state, the guidance determining unit 565 resets the determination result that the player character PC1 is in the guidance state. The predetermined operation state includes at least one of a state in which the player character PC1 has attacked the enemy characters EM1 and EM2, and a state in which the player character PC1 has been attacked by the enemy characters EM1 and EM2. As a result, it is possible to switch to an effect different from the effect in the guidance state at an appropriate timing, and the game becomes more interesting.

In particular, as one of the above-mentioned effects, the voice output control means 566 outputs the guide music 1 (first music) according to the guide state. As a result, the music piece suitable for the guide state is output from the speaker 62, so that the user can feel a sense of presence and a feeling of dynamism, and can play a more entertaining game.

When the guidance determination unit 566 resets the determination result that the guidance state is the guidance state, the voice output control unit 566 outputs the music to be output from the guidance music (first music) to another music (second music such as battle music). Songs). As a result, since music corresponding to various states is output from the speaker 62, the game becomes more entertaining.

In particular, the game space of this game is a space in which battle areas CA1 to CA8 and movement areas MA1 to MA11 are seamlessly connected. Since it is seamless, there is no load screen when the player character PC1 moves in the areas CA1 to CA8 and MA1 to MA11, and it can be said that the timing for changing the music is poor. In such a game space, in the present embodiment, the guide song is switched to another song at the timing when the player character PC1 takes a predetermined operation state. As a result, it is possible to provide a realistic and dynamic sound that does not cause the user to feel discomfort.
