[0014]

Embodiments of the present invention will be described below with reference to the drawings. <Configuration of Game System> First, a game system that executes a volleyball video game according to the present embodiment
(Valley game machine) will be described. FIG. 1 is a diagram illustrating a configuration example of a valley game machine. As shown in FIG. 1, the valley game machine includes a video game machine A and a board 1 housed in the video game machine A.

Here, the video game machine A is a television monitor (hereinafter, referred to as "monitor") TV and speaker L.
SP, RSP, and control panel CP.
The control panel CP has a first operation system C1 and a second operation system C2 so that two players can simultaneously participate in the game. The first operation system C1 includes a first lever L1 and a first lever L1.
It consists of buttons C1a to C1c. On the other hand, the second operation system C2
Comprises a second lever L2 and second buttons C2a to C2c. Further, the control panel CP includes a start button SL for playing a game using the first operation system C1,
A start button ST for playing a game with the operation system C2,
And a coin slot CH.

The board 1 includes a CPU 1, a ROM 3, a RAM 4, an interface circuit 7, an audio system circuit 8, and a display system circuit 9 connected to the CPU 1 via buses (address bus, data bus, control bus) B. Become.

Here, the ROM 3 stores a basic program constituting an operation system, a game program of a volleyball video game, and various data. The RAM 4 is used as a work area by the CPU 1. The interface circuit 7 captures operation data from the control panel CP. The audio circuit 8
An audio signal is supplied to the speakers LSP and RSP. The display system circuit 9 has a display buffer (VRAM) 10 for storing video (image) data to be displayed on the monitor TV, and a video signal based on the storage contents of the display buffer 10.
(Image signal) to the monitor TV.

The operation of the above-mentioned volleyball game machine is as follows. That is, in the valley game machine, when the power is turned on, the CPU 2 initializes the audio system circuit 8, the display system circuit 9, and the video game machine A based on the operating system stored in the ROM 3. Do.

Subsequently, the CPU 2 reads out the game program recorded in the ROM 3 and data used when executing the program, and loads the data into the RAM 4. Further, the CPU 2 reads the image data of the valley game from the ROM 3 and stores the image data in the RAM 4. Thereafter, the CPU 1 advances the game based on the game program loaded in the RAM 4 or an input signal (command) input by the game player via the control panel CP. That is, the CPU 1 appropriately controls image processing, controls internal processing, and the like based on the game program or the contents of instructions from the game player. Here, the control of the image processing includes, for example, issuance of various drawing processing instructions to the display system circuit 9 and the like. The control of the internal processing is, for example, an operation or the like in accordance with an operation of the control panel CP.

Here, as an example of the control of the image processing, an operation in the case of displaying a three-dimensional object image using a polygon on a monitor TV will be described. As a premise,
A table for storing the absolute coordinate data of the polygons forming the object, the rotation amount data of the object, and the movement amount data of the object is created in the RAM 4. Further, a table storing texture address data and color pallet address data is created in the display system circuit 9. Next, the CPU 2 reads the rotation amount data of the object, the movement amount data of the object, and the absolute coordinate data of the polygon from the table of the RAM 4 and converts the absolute coordinate data of the polygon into polygon vertex address data. Here, the polygon vertex address data is data of the vertex position (coordinates) in the display buffer 10 of an object configured as an aggregate of polygons (polygons). Then, CPU1
Is the texture address data from the table above,
The color palette address data is read, and these data and polygon vertex address data are transferred to the display system circuit 9.

Next, the display system circuit 9 sets the range of the polygon surface (the range surrounded by the straight line connecting the vertices of the polygon) in the display buffer 10 based on the polygon vertex address data. Subsequently, the display system circuit 9 includes a RAM
Based on the texture address data and color pallet address data stored in No. 4, texture data and color pallet data corresponding to polygon vertex address data are read out. Subsequently, the display system circuit 9 writes the read drawing data in the range of the set polygon surface. This process is generally called “texture pasting”. Thus, the display buffer 10 stores the display image data of the object. Then, the display circuit 9 outputs the storage contents (display image data) of the display buffer 10 to the monitor TV. As a result, an image based on the contents stored in the display buffer 10 is displayed on the screen of the monitor TV. <Overview of the Valley Game>
The game program recorded in the OM 3 is loaded into the RAM 4, and subsequently, the CPU 2 executes the game program to execute a volleyball video game (hereinafter, referred to as a volleyball game)
This is called a "ballet game." ) To the game player.

That is, the volleyball game machine monitors a volleyball court installed in a virtual three-dimensional game space on a monitor TV.
Display on the screen. Specifically, as shown in FIG. 2, the court 50 in a state of looking down from a slightly upper side of the side line is displayed on the screen of the monitor TV. further,
The volleyball game machine displays two volleyball teams playing volleyball on the court 50 on the screen of the monitor TV. For example, in FIG. 2, the M team is displayed on the left side of the page, and the E team is displayed on the right side of the page.

Each of the player characters M (M1 to M) constituting one of the two teams (M team)
6) is operated by the game player, and each player character E (E1 to E6) constituting the other team (E team) is CP
By operation by U2 or another game player,
A volleyball game is played.

The volleyball game executed by the volleyball game machine proceeds in accordance with the actual volleyball rules. In other words, the team that pre-empts three sets of sets contested by the pre-emption of 12 points wins. <Operation Method of Volleyball Machine> Next, a method of operating the volleyball game machine by the game player will be described with reference to FIGS. 3 to 6 are explanatory diagrams of the operation method of the volleyball machine. By the way, the volleyball game machine according to the present embodiment can be played using either the first operation system C1 or the second operation system C2 when the game player plays the volleyball game machine alone. I have. The operation method of the valley game machine includes a first operation system C1 and a second operation system C2.
And the operation method is the same regardless of whether the operation character is the player character M or the player character E. Hereinafter, the case where the first operation system C1 is used will be described as an example, and the second operation system C2 will be described as necessary.

When the first operation system C1 is used, the game player operates each player character M. The operation of each player character M generally includes an operation of performing a serve operation, an operation of performing a receive operation, an operation of performing an attack (spike) operation, and an operation of performing a block operation. The operation of raising the toss and the operation of rotating the toss by the player character M serving as the setter are automatically performed by the CPU 2. However, these operations may also be performed by the operation of the game player.

When performing a serving operation, any one of the first buttons C1a to C1c of the first operation system C1 is assigned as a serving button. Each player character M
In principle, it is set to perform floater serve,
The operation until the ball B is thrown up is automatically performed by the CPU 2. Then, when the game player presses the serve button in a timely manner when the ball B is thrown up, the player character M performs an operation of hitting the ball B, and the ball B flies toward the opponent's court.
Depending on the timing of pressing this serve button, the ball B
Speed, course and landing position are determined. When the timing is missed or the serve button is not pressed, the player character M swings the ball B.

The operation of the receiving operation is performed as follows. That is, when the player character M hits (hits) the ball B by the above-described serving operation or the like, the landing position of the ball B is determined. Then, as shown in FIG. 3, the circular first cursor K1 indicating the landing position of the ball B
Is displayed on the monitor TV. Subsequently, the CPU 2 allows the player character M (for example, the most appropriate one to receive the ball B) among the plurality of player characters M1 to M6 (for example,
The player character M closest to the first cursor K1: the player character M2 in FIG. 3 is determined, and a circular second cursor K2 is displayed below the feet.

Then, the game player moves the player character M2 on which the second cursor K2 is displayed to the first lever L.
1 enables operation. At this time, when the game player moves the player character M2 toward the cursor K1, the second cursor K2 also moves with the movement of the player character M2. When the first cursor K1 and the second cursor K2 are at a predetermined distance before the ball B reaches the landing position, the player character M2 becomes inoperable, and as shown in FIG.
Automatically moves to above the first cursor K1, and the first cursor K1 and the second cursor K2 completely coincide and overlap each other. Subsequently, the player character M2 automatically receives the ball B flying to the landing position. And
The received ball B flies properly toward a setter player character (for example, the player character M4 in FIG. 3).

The operation of the attack operation is performed as follows. That is, by the above-described receiving operation, the ball B
Is received toward the setter player character M, three player characters M (for example, two from the front guard and one from the rear guard) to perform an attack operation from the player characters M other than the player character M as the setter ) Is selected, and the first button C1a to the first button C1a to
C1c is assigned.

At this time, when the game player presses any one of the first buttons C1a to C1c, as shown in FIG. 5, the player character M (for example, player character M2) corresponding to the pressed button becomes Start running motion. Subsequently, the player character M whose ball B is the setter (FIG. 5)
Then, when the player character M4) is reached, the player character M4 automatically raises the toss ball. Then, the player character M2 performs an attack operation. The course and landing position of the attacked ball B are determined by the first buttons C1a to C1a.
It changes according to the timing when C1c is pressed.

When the setter player character M4 raises the toss ball, the ball B changes its color to another color for a predetermined time. At this time, when the game player presses any of the first buttons C1a to C1c, the player character M (player character M2) as an attacker performs an attack operation according to the pressed button. That is, when the first button C1a is pressed, the player character M2 attacks the ball B with normal strength. When the first button C1b is pressed, the player character M2 attacks the ball B with a strong hit. Further, the first button C1
When c is pressed, the player character M2 performs a feinting operation (an operation of returning the ball B to the opponent's court lightly).

If a plurality of first buttons are pressed before the ball B reaches the setter (player character M4), each player character M to which each of the first buttons C1a to C1c has been assigned has a time difference. Make an attack. That is, the corresponding player character M starts running in the order in which the buttons are pressed, and the setter raises the toss ball against the player character M corresponding to the button pressed last.
Then, the player character M corresponding to the first and second pressed buttons respectively performs a miss swing operation, and the player character M corresponding to the last pressed button actually performs an attack operation.

This time lag attack results in a time difference between two players or three players depending on the number of buttons pressed until the ball B reaches the setter. Also, the first buttons C1a to C1C
The order in which each player character M performs a time difference attack changes in the order in which 1c is pressed. FIG. 5 shows a button (for example, a first button C1a) corresponding to the player character M3 and a button (for example, the first button C1) corresponding to the player character M2.
By pressing the first buttons C1a to C1c in the order of b), the player character M3 and the player character M2 become 2
The appearance of performing a human time lag attack is shown.

The operation of the block operation is performed as follows. That is, as described above, when the toss ball rises from the setter, the toss ball changes color to another color for a predetermined time. At this time, as shown in FIG. 6, the second buttons C2a to C2c of the second operation system C2 are assigned to the avant-garde of the opponent team (for example, in FIG. 6, the player characters E1 to E3). Then, when the game player presses the second buttons C2a to C2c, the player character E corresponding to the pressed second button performs a block operation.

That is, of the second buttons C2a to C2c,
When two buttons are pressed, two player characters E corresponding to each perform a block operation, and the button
When both are pressed, the three player characters E perform the block operation. Thus, the second buttons C2a to C2a-C
2 blocks or 3 blocks can be operated according to the number of times 2c is pressed.

FIG. 6 shows how the player characters E1 and E2 perform a block operation. In this block operation, success or failure of the block operation is generated depending on the timing of pressing the second buttons C2a to C2c. Although the operation of the block operation has been described using the second operation system C2, the operation of the block operation by the first operation system C1 is performed similarly to the second operation system C2. <Perspective position of volley game machine> The volley game machine according to the present embodiment changes the viewpoint position (camera position) in accordance with the position of the ball B, whereby the court 5 shown in FIG.
0 is displayed on the screen of the monitor TV. FIG. 7 is an explanatory diagram showing a method of changing the viewpoint position.

FIG. 7 shows a coat 50 viewed from directly above.
Are shown, and a viewpoint position (camera position) EP with respect to the court 50 is shown. The viewpoint position EP is set such that the vertical plane including the visual axis EA is always perpendicular to the extension of the side line of the court 50 (always parallel to the volleyball net). Also, the viewpoint position EP
Is set so that the visual axis EA and the center of the ball B are on the same plane when the ball B is stopped.
And it exists on the near side of the side line of the court 50 and has each vertex on each line of sight EL of the viewpoint position EP,
Further, the court 50 projected on a rectangular plane orthogonal to the visual axis EA becomes a part of the court 50 displayed on the screen of the monitor TV. Then, when the ball B moves along the side line direction due to a serving operation or the like, the viewpoint position EP moves along a locus parallel to the side line of the court 50.

At this time, the viewpoint position EP moves based on the landing position of the ball B. That is, when the ball B is hit (hit) by serving or the like, the landing position is determined as described above, and the first cursor K1 is displayed at the landing position. Here, for example, when the ball B is launched from the service area of the court on the right side of the paper of FIG. 7 and lands on the first cursor K1 shown on the court on the left side, the viewpoint position EP is set after the end of the serving operation. , And move toward the left side of the page. At this time, the viewpoint position EP
Is faster than the speed of the ball B until its visual axis EA is on the same plane as the center position of the movement start point of the ball B and the midpoint of a straight line connecting the center of the first circle K1. It accelerates at a speed and then gradually decreases in speed, and stops when the visual axis EA and the center of the first cursor K1 are on the same plane. Then, after the viewpoint position EP stops, the ball B appears on the screen of the monitor TV.

FIG. 8 is a diagram showing a screen display example of the valley game machine displayed on the screen of the monitor TV when the viewpoint position EP is at the position before the start of movement shown in FIG. FIG. 9 is a diagram showing a screen display example of a valley game machine displayed on the screen of the monitor TV immediately after the viewpoint position EP stops at the movement end position shown in FIG. 7, and FIG. FIG. 7 is a diagram showing a state in which a ball B appears on the screen after the screen is displayed.

Further, as shown in FIG. 11, the viewpoint position EP moves upward when the ball B disappears from the upper edge of the screen of the monitor TV to the outside of the screen. Has become. 8 to 11, only the range actually surrounded by the rectangular frame indicating the screen of the monitor TV is actually displayed on the screen of the monitor TV. <Processing by Valley Game Machine> Next, the processing of the volley game machine when the above-described volley game is executed will be described. When the above-described initialization is completed, the CPU 2 of the valley game machine displays a start screen (not shown) on the monitor TV by executing the game program. continue,
The CPU 2 displays “INJECT COIN” on the monitor TV.
Is displayed, and a state of accepting insertion of a coin from the coin insertion slot CH is established.

Subsequently, when a coin is inserted from the coin insertion slot CH, the CPU 2 detects the number of inserted coins (the number of credits) and displays the number on the monitor TV. At this time, when one coin has been inserted, the CPU 1 determines “PUS
The character “H 1P BUTTON” is displayed on the monitor TV. On the other hand, when two or more coins are inserted, C
PU1 is “PUSH 1P OR 2P BUTTO
"N" is displayed on the monitor TV.

When the game player presses the start button SL or the start button ST, the valley game in the one-play (to CPU) mode starts.
On the other hand, the start button S
When L and the start button ST are pressed, the valley game in the two-play (competition) mode starts.

The tables 4a and 4b are created in the RAM 4 prior to the start of the volleyball game. These tables 4a and 4b are used in the above-described operation processing of the receiving operation and the movement processing of the viewpoint position EP. FIG. 12A is an explanatory diagram of a two-play table 4a, and FIG. 12B is a one-play table 4a.
It is explanatory drawing of b.

As shown in FIG.
In a, the landing position of the ball B and its arrival time are stored in association with information (timing information) of the timing at which the ball B is launched by the operation of the game player. Here, the timing information is the timing at which the serve button or the attack button is pressed. That is, when the action of the player character M or the player character E is a serve action, the first button C1a to C1b or the second button C2a after the ball B is thrown up by the player character M or the player character E serving as a server. ~ C
Time information until any of 2b is pressed. Also,
When the motion of the player character M or the player character E is an attack motion, the first button C1 assigned as the attack button after the ball B is received by either the player character M or the player character E
Time information until a to C1c or the second button C2a to C2c is pressed.

On the other hand, the table 4b stores the landing position of the ball B and its arrival time in association with random numbers detected by the CPU 2 from a random number table (not shown). FIG.
The tables 4a and 4b shown in (a) and (b) are used as tables for the ball B hit by the serve operation. In addition, the table for the ball B hit by the attack operation is created on the RAM 4. It may be. Further, a table for determining the landing position may be created for each player character M or each player character E.

In the RAM 4, a position table (not shown) for storing position data of the viewpoint position EP, the ball B, each player character M, and each player character E is created. The position data stored in the position table is updated each time the CPU 2 or the display circuit 9 processes an image for one frame.

As the processing during the execution of the volleyball game, first, the receiving processing by the volleyball machine will be described. FIG. 13 is a flowchart showing the receiving process. This receiving process is started, for example, when the opposing team hits the ball B. However, here, a process when the game player operates each player character M using the first operation system C1 when the ball B is launched from the E team will be described as an example.

In FIG. 13, in S101, the landing position of the ball B to be hit is determined. That is, when the valley game is two-play, the CPU 2 acquires timing information (time information) based on a serve signal or an attack signal (corresponding to an input signal) received from the control panel CP via the interface circuit 7 and The landing position corresponding to the timing information is stored in the table 4a.
(See FIG. 12A), the landing position is determined as the landing position of the ball B to be hit. On the other hand, when the valley game is one play, the CPU 2 randomly detects one random number from a random number table (not shown), reads a landing position corresponding to the random number from the table 4b, and lands the ball B. Determine as position. Then, the CPU 2 advances the processing to S102.

In S102, the CPU 2 reads the arrival time corresponding to the landing position read in S101 from the table 4a or 4b. And CPU2
Advances the process to S103.

In S103, the CPU 2 calculates the initial velocity of the ball B that can reach the landing position within the arrival time read in S102. Then, the CPU 2 proceeds to S1
Proceed to 04.

In S104, the CPU 2 causes the ball B to fly at the initial speed obtained in S103. That is, the CPU 2
The state of the ball B flying at the initial speed obtained in S103 is displayed on the monitor TV. Then, the CPU 2 proceeds to S
Proceed to 105.

In S105, the CPU 2 displays the first cursor K1 at the landing position of the ball B determined in S101 (see FIG. 3). Then, the CPU 2 executes the processing in S10
Proceed to 6.

In S106, the CPU 2 selects the most appropriate player character M for the first cursor K1.
For example, the CPU 1 calculates the distance between the position of the first cursor K1 and each player character M stored in a position table (not shown), and selects the player character M with the shortest distance as an appropriate player character. And CPU2
Proceeds to S107.

In S107, the CPU 2 displays the second cursor K2 under the foot of the image of the player character M selected in S106. Then, the CPU 2 proceeds to S1
Proceed to 08.

In S108, the CPU 2 operates the first lever L
1 is assigned to the operation of the player character M selected in S106, and the position of the second cursor K2 is detected. Then, the CPU 2 advances the processing to S109.

In S109, the CPU 2 determines whether or not the distance between the first cursor K1 and the second cursor is less than a predetermined receiving success distance stored in the RAM 4. At this time, when it is determined that the distance is less than the receiving success distance (S1
09; YES), the CPU 2 advances the processing to S110. On the other hand, when it is determined that the distance is equal to or longer than the receiving success distance (S109; NO), the CPU 2 advances the processing to S112.

When the process has proceeded to S110, the second cursor K2 and the first cursor K1 are superimposed in a completely coincident state. Thereby, the player character M
Is corrected to the position of the first cursor K1 (the landing position of the ball B). Then, the CPU 2 executes the processing in S11
Proceed to 1.

At S111, the CPU 1 causes the player character M whose position has been corrected to the landing position to perform a receiving operation. As a result, the state in which the ball B that has flown toward the landing position is properly received and flies toward the setter player character M is displayed on the monitor TV. When the process in S111 ends, the receiving process ends.

If the processing has proceeded to S112, the CPU
2 determines whether or not the ball B has reached the landing position in S112. At this time, if the ball B has not yet reached the landing position (S112; NO), the CPU 2
The process returns to S108. On the other hand, when the ball B reaches the landing position (S112; YES), the CPU 2
Advances the process to S113.

If the processing has proceeded to S113, the CPU
2 displays on the monitor TV that the game player has made a mistake (miss display). Then, when the processing in S113 ends, the receiving processing ends.

After the processing in S113 is completed, the CP
U2, for example, if the M team has the right to serve,
The process of transferring the serve right to the E team is performed. On the other hand, C
The PU2 adds 1 to the point number of the E team when the E team has the serve right. When the point number of the E team becomes 12 by adding one point to the E team, the CPU 2 ends the set. Furthermore, when the number of sets acquired by the E team becomes three by ending the sets, the CPU 2 ends the valley game.

Next, an attack process by the valley game machine will be described. 14 to 16 are flowcharts illustrating the attack process. This attack process is started, for example, by performing the receiving operation of the ball B by the process of S111 described above. However, here, a case where the game player causes the player character of the M team to perform an attack operation using the first operation system C1 is described.
This will be described as an example.

In FIG. 14, in S201, the CPU 2
However, among a plurality of player characters M constituting the M team, a plurality of player characters M (for example, three players) capable of performing an attack operation are determined. Then, the CPU 2 advances the processing to S202.

In S202, the CPU 2 assigns the first buttons C1a to C1c to the three player characters M determined in S201, and
.. C1b are received via the interface circuit 7. Then, the CPU 2 advances the processing to S203.

At S203, the CPU 2 determines that the first button C1a assigned at S202 before the received ball B reaches the setter player character M.
To C1c are determined. At this time, when it is determined that any button has been pressed (S20
3; YES), the CPU 2 acquires the time from when the ball B is received to when this button is pressed as timing information, and stores it in the RAM 4. And CP
U2 advances the processing to S204. On the other hand, when it is determined that none of the buttons has been pressed (S203; N
In O), the CPU 2 advances the processing to S206.

That is, the CPU 2 displays, on the monitor TV, a state in which the corresponding player character M attacks the ball B with a strong hit toward the court on the E team side. When the processing in S224 ends, the attack processing by the volleyball machine ends.

After the completion of the attack processing, the C
PU2 determines whether or not the attacked ball B spans the net. At this time, if the CPU 2 determines that the ball B does not extend over the net, the process proceeds to the receiving process of the E team. On the other hand, when the CPU 2 determines that the ball B is connected to the net, the state of the ball B connected to the net is displayed on the monitor TV, and the above-described error display is performed. Then, the CPU 2 executes a process in a case where the above-described mistake has occurred.

When the volleyball game is two-play, the volleyball machine performs the block processing by the player character (player character E) constituting the opposing team (here, team E) in parallel with the above-mentioned attack processing. Execute FIG. 17 is a flowchart showing the block processing. This block processing starts when the ball B tossed by the processing of S209 or S216 in the above-described attack processing changes color.

In FIG. 17, in S301, the CPU 2
However, among the plurality of player characters E constituting the E team, a plurality (for example, three) of player characters E participating in the block are determined. Then, the CPU 2 proceeds to S30.
Proceed to 2.

At S302, the CPU 2 gives the player character E determined at S301 the second button C2a to C2c.

In S303, the CPU 2 assigns the second button C assigned in S302 before the discoloration of the ball B ends.
It is determined whether any of 2a to C2c has been pressed. At this time, if it is determined that any button has been pressed (S
303; YES), the time from when the ball B starts discoloring to when this button is pressed is acquired as timing information and stored in the RAM 4. And CPU2
Advances the process to S304. On the other hand, if it is determined that none of the buttons has been pressed (S303; NO), this block processing ends, and the processing shifts to receive processing by the E team. When the volleyball game is played in two plays, the receiving process by the E team is
The same process as the receive process shown in FIG. 13 is performed.

If the processing has proceeded to S304, the CPU
2 determines whether a button other than the button determined to have been pressed in S303 before the discoloration of the ball B is pressed. At this time, if it is determined that the button has been pressed
In (S304; YES), the time from when the ball B starts discoloring to when this button is pressed is acquired as timing information and stored in the RAM 4. And CPU
In step S2, the process proceeds to S306. On the other hand, when it is determined that none of the buttons has been pressed (S304; NO)
Then, the CPU 2 advances the processing to S305.

When the processing has proceeded to S305, the CPU
2 causes each player character E to which the button determined to have been pressed in S303 to be assigned to perform a block operation. That is, the CPU 2 displays on the monitor TV how the corresponding player character E performs the block operation. This block operation is performed based on the timing information acquired in S303. When the processing of S305 ends, the block processing of the valley game machine ends. If the block succeeds, the process proceeds to the receiving process by the M team (the process shown in FIG. 13). If the block fails, the process proceeds to the receiving process by the E team.
Further, when the blocked ball B is out, processing is performed when an error occurs.

When the processing has proceeded to S306, the CPU
2 is S303 and S before the discoloration of the ball B ends.
It is determined whether a button other than the button determined to have been pressed in 304 is pressed. At this time, if it is determined that the button has been pressed (S306; YES), the time from when the ball B starts discoloring to when this button is pressed is acquired as timing information and stored in the RAM 4.
Then, the CPU 2 advances the processing to S307. On the other hand, when it is determined that none of the buttons has been pressed
In (S306; NO), the CPU 2 advances the processing to S308.

If the processing has proceeded to S307, the CPU
2 causes each player character E to which the button determined to have been pressed in each of S303 and S304 to perform a block operation. That is, the CPU 2 causes the monitor TV to display a state in which the corresponding player character E performs the two-block operation. This block operation is performed in steps S303 and S303.
This is performed based on the timing information acquired in 304 respectively. When the processing of S307 ends, the block processing of the valley game machine ends. After that, the same processing as after the processing of S305 is performed.

If the processing has proceeded to S308, the CPU
2 causes each player character E to which the button determined to be pressed in S303, S304, S306 to be assigned to perform a block operation. That is, the CPU 2 displays on the monitor TV how the corresponding player character E performs the three-block operation. This block operation is performed in steps S303 and S303.
The processing is performed based on the timing information acquired in steps 304 and S306, respectively. When the processing of S308 ends, the block processing of the valley game machine ends. After that, the same processing as after the processing of S305 is performed.

Next, the process of changing the viewpoint position (camera position) by the volleyball machine will be described. FIG. 18 is a flowchart illustrating a viewpoint position changing process. The process of changing the viewpoint position starts when the play start screen of the volleyball game (see FIG. 8) is displayed.

In FIG. 18, in S401, the CPU 2
Sets the viewpoint position EP to the position of the ball B. At this time, the viewpoint position EP is set such that the visual axis EA of the viewpoint position EP and the center of the ball B are on the same plane. Then, the CPU 2 causes the monitor TV to display a play start screen (see FIG. 8) in a state where the viewpoint position EP is set to the ball B. Then, the CPU 2 advances the processing to S402.

In S402, the CPU 2 determines the landing position of the ball B. The process of S402 is performed by

In S407, the CPU 2 sets the viewpoint position EP
Is moved toward the landing position (cursor K1). At this time, the viewpoint position EP moves while drawing a trajectory parallel to the side line of the court 50 at a speed higher than the speed of the ball B (see FIG. 7). As a result, a state where the court 50 relatively moves rightward toward the screen is displayed on the monitor TV, and a state where the ball B disappears from the right edge of the screen to the outside of the screen is displayed. . Then, the CPU 2 advances the processing to S408.

In S408, the CPU 2 sets the viewpoint position EP
After passing through the intermediate position calculated in S404, the speed is gradually reduced. Then, the CPU 2 advances the processing to S409.

In S409, the CPU 2 determines that the viewpoint position EP
Is determined to have reached the landing position (cursor K1). That is, the CPU 2 determines whether or not the viewpoint position EP and the center of the cursor K1 are on the same plane. At this time, if the viewpoint position EP has not reached the landing position (S409; NO), the CPU 2 proceeds to S
The processing returns to 408, and the processing of S408 and S409 is repeated until a determination of YES is made in S409. On the other hand, when the viewpoint position EP reaches the landing position (S40)
9; YES), the CPU 2 advances the processing to S410.

When the processing has proceeded to S410, the CPU
2 stops the movement of the viewpoint position EP. At this time, the screen shown in FIG. 9 is displayed on the screen of the monitor TV. Then, the CPU 2 advances the processing to S411.

At S411, the CPU 2 determines whether or not the ball B has flew to the vicinity of the cursor K1. At this time, if the ball B has flew to the vicinity of the cursor K1 (S411; YES), the CPU 2 advances the processing to S412. On the other hand, the ball B moves to the cursor K
If the CPU 2 has not flew to the vicinity of S1 (S411; NO), the CPU 2 returns the processing to S411, and this S411
The process of S411 is repeatedly performed until the determination of YES is made.

If the processing has proceeded to S412, the CPU
2 determines whether the ball B has been received by any of the player characters M. At this time, if it is determined that the ball B has been received (S412; YES), the CPU 2 returns the processing to S401, and this S412
The processing of S401 to S412 is repeatedly performed until the determination of NO is made. On the other hand, when it is determined that the ball B is not received (S412; NO), the CPU 2
Advances the process to S413.

When the processing has proceeded to S413, the CPU
2 maintains the state where the viewpoint position EP is fixed. This S
When the process of 413 ends, the process of changing the viewpoint position by the volleyball game machine ends. Thereafter, the CPU 2 displays the play start screen again on the screen of the monitor TV. However, when the set is completed, the CPU 2 displays a set end screen (not shown), and when the volleyball game is ended, displays a game end screen (not shown). <Effects of the present embodiment> According to the volleyball game machine of the present embodiment, when the game player performs a receiving operation, the cursor K1 indicating the landing position of the ball B is displayed on the monitor TV, and the game player moves the cursor K1. When the distance between the cursor K1 and the player character M (cursor K2) becomes the receive success distance by operating the player character M closest to K1, the CPU 2 automatically adjusts the receive operation to the player character M. To be performed.

Therefore, even if the game player is unfamiliar with the valley game machine or is not proficient in operating the controller, it is possible to cause the player character M to perform the receiving operation more easily than in the past. Therefore, it is possible to provide a game player with a valley game machine that can be enjoyed regardless of the proficiency of the controller, and to make a game player who has conventionally tended to avoid the valley game machine interested in the valley game machine. Become.

Further, since the second cursor K2 is displayed below the player character M to be subjected to the receiving operation, the game player can easily grasp the player character M to be operated.
