Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus and a game apparatus provided with the image processing apparatus. More specifically, the present invention relates to an image processing apparatus for performing image processing for games such as martial arts games, and this game. And a game device for implementing the game.

[0002]

2. Description of the Related Art With the development of computer graphics technology in recent years, image processing devices such as game devices and simulation devices have become widely used. For example, a game device includes a peripheral (peripheral device) such as a joystick (operation stick), a button, and a monitor, and a game device main body that executes data communication with the peripheral, image processing, sound processing, and the like. I have. Image processing in this game device occupies a very large weight in increasing the commercial value, and in recent years, the technology of playing back moving images has also been refined.

[0003] As one example of this game apparatus, "Title Fight (trademark)" manufactured by SEGA ENTERPRISES is known. In this device, a character (warrior) is composed of a sprite (one picture), and a background and the like are composed of a scroll screen.

[0004] However, in this case, the character cannot be three-dimensionally expressed by changing the viewpoint. Therefore, in recent years, a three-dimensional shape is configured from a plurality of polygons, and a texture (pattern) is mapped to the polygon so that the character can be displayed even when viewed from a predetermined viewpoint. .

[0005] As an example of this, a three-dimensional character is rendered with polygon data subjected to texture mapping, and a special background portion required to move in accordance with the movement of the character or the change of the viewpoint is a polygon with a texture. 2. Description of the Related Art There is known a TV game apparatus which draws data using data and draws other backgrounds on a scroll screen (for example, a fighting game of "Virtua Fighter (TM)" manufactured by SEGA ENTERPRISES CO., LTD.). In this case, in accordance with the movement of the character or the change of the viewpoint, coordinate conversion and perspective conversion of textured polygon data forming the character and a special part of the background are performed, and drawing for each frame is performed. .

Thus, as compared with the case where the character is composed of a sprite or a scroll screen, the character (for example, the aforementioned warrior) and a special partial screen (for example, the aforementioned warrior ring) closely related to the movement of the character are compared. ) Can be expressed three-dimensionally from a predetermined viewpoint.

[0007]

In an image processing apparatus such as the above-mentioned conventional TV game apparatus, the amount of data processing for coordinate conversion and texture mapping for each frame accompanying the movement of the character and the change of the viewpoint becomes enormous. The calculation load of the CPU of the data processing device main body such as the TV game device main body has been significantly increased. In order to cope with this increase in calculation load, a CPU having a high calculation capability is required, which has contributed to an increase in manufacturing cost.

On the other hand, if image data is to be processed at a relatively high speed using a CPU having a processing capacity that can be compromised, it is necessary to limit, for example, the number of characters and the amount of texture mapping processing. At present, the degree of freedom in production is limited, and it is difficult to improve image quality. In addition, there is a disadvantage that the degree of freedom in production is insufficient to express the fun of the game.

Therefore, in a conventional game device using polygons, in order to solve this kind of problem, the number of polygons that can be used for creating an image processing program is reduced while using a CPU having a compromised capacity. Regulation is being pursued. In this conventional example, it is possible to effectively use the restricted number of polygons by allocating more polygons to a part of the display body composed of polygons, for example, to a necessary part such as the entire character or the head of the character. It is considered. However, in this prior art, the number of polygons in a portion to which more polygons are allocated is maintained as it is throughout the entire image processing, so that the number of polygons is always used effectively. There was a problem that it was difficult.

Further, in the conventional game machine, since the movement of the warrior is controlled by moving the operation mechanism, a high score can be given to the opponent's warrior simply by activating the operation mechanism frequently without any discretion. In some cases, it has been determined that the game environment has been obtained, and a state far from reality occurs, and there is a disadvantage that a game environment full of realism cannot be provided. On the other hand, if the operation of the operation mechanism is effective, it is necessary to give a high score.
However, in the conventional game device, it is difficult to distinguish whether the operation of the operation mechanism is effective in the progress of the game or is random and unsightly.

In the conventional game apparatus, a plurality of characters are respectively composed of polygons, and when a plurality of characters overlap with the viewpoint, a higher priority is given to the polygon on the near side with respect to the viewpoint. Previously, a polygon on the near side was preferentially displayed with respect to other polygons. As a result, in the case of a martial arts game in which a plurality of warriors appear, there is an inconvenience that the back of the front warrior is displayed on the screen, and the warrior beyond the back is not displayed.
When a warrior, a character on the near side, is an operation target for a player, control of the operation target may not be sufficiently effective unless an image of the opponent warrior is displayed. Momentum, in this case, it may be possible to give higher display priority to the polygon of the opponent's character,
The fact that the front warrior to be operated by the player is not displayed also makes it difficult for the player to operate.

In addition, in the conventional game apparatus, the life of the warrior, which is a display body, is displayed on a part of the display as a life counter (life measurement meter) by software and provided to the player. . When the life counter becomes equal to or less than a predetermined value, the game in the game device is ended. For example, in the case of the virtual fighter (TM), when one fighting scene ends and a new fighting scene is developed, a life count value of the same amount (length) as the previous screen is prepared. Was. However, when actually fighting, the damage given to the warrior is accumulated as it is even if the fighting scene is updated, so that there is a drawback that this actual situation is not accurately reflected on the game device.

In short, conventional image processing apparatuses such as game apparatuses have a problem that effective image processing cannot be achieved in achieving a game simulating reality such as martial arts. .

Accordingly, the present invention has been made to solve this problem. A first object of the present invention is to provide an image processing apparatus capable of effectively using a limited number of polygons.

[0015] A second object of the present invention is to provide an image processing apparatus in which such a sense of reality is more reflected in consideration of, for example, that damage and fatigue given to a warrior are actually accumulated. Aim.

A third object of the present invention is to perform image processing on a plurality of display objects such as characters in association with each other, and to display a plurality of display objects even when a plurality of display objects overlap with a viewpoint. It is an object of the present invention to provide an image processing apparatus that can simultaneously display and control a display body effectively.

A fourth object of the present invention is to effectively distinguish between frequently operating the operating mechanism without any inconvenience and effectively operating the operating mechanism. An object of the present invention is to provide an image processing apparatus that prevents a high evaluation from being given.

In order to achieve the fifth object, a game machine according to a twelfth aspect of the present invention comprises a display means and an image processing apparatus according to any one of the first to tenth aspects.

[0031]

In the image processing apparatus according to the first aspect, when the image processing means deforms and displays the display, the number of polygons constituting the display is increased. For this reason, as in the image processing apparatus according to the second aspect, the polygon structuring means forms at least a part of the display object with a minimum number of polygons, and sets the display object having the minimum number of polygons. When it is not necessary to deform and display the portion, the number of polygons is maintained, and when it is necessary to deform the portion, the number of polygons of this portion is increased by the polygon number increasing means. Therefore, when there is no need to deform this portion, for example, the surplus polygon number can be applied to other display objects, and the limited number of polygons can be effectively used.

Further, by increasing the number of polygons, such a deformation can be displayed or a more detailed deformed image can be formed. If this part needs to be deformed, the number of polygons in this part is increased, which limits the number of polygons in other display objects, but the viewer's attention is focused on this deformed part It is considered that the inconvenience due to this restriction is reduced.

In the apparatus according to the third aspect, the polygon forming means forms a part of the display body into a polyhedron in which each surface is formed of one polygon, and the polygon number increasing means comprises a part of the display body. Is deformed and displayed, each surface of the polyhedron is increased to a plurality of polygons. By using a polyhedron in this way, the number of polygons can be reduced as much as possible, and when it is necessary to deform and display the polyhedron, the number of polygons on each surface is increased.

According to a fourth aspect of the present invention, the image processing means comprises the display body including first and second characters simulating the body, respectively, and a head of the first character and a second character. By judging the collision with the character, it is possible to reliably grasp the case where the deformation of the head is necessary. The polygon structuring means forms the head of the first character as a hexahedron in which each face is composed of one polygon.
By increasing the number of polygons on each surface of the face, a deformed display of the head is enabled.

According to the fifth aspect of the present invention, each face of the head of the character is formed into a rectangular shape which can be constituted by one polygon. Minimize the number.

In the apparatus according to the sixth aspect, the image processing remaining capacity display means sequentially changes the total remaining power as the image processing progresses, and reflects the result of the image processing on the remaining image processing power. Here, as this total reserve is sequentially reduced,
For example, in image processing in a fighting game, it is possible to accurately reproduce damage actually accumulated on a display body.

In the invention according to claim 7, the storage means stores a value obtained by stepwise reducing the total remaining power. The total surplus changing means sequentially reads out the total surplus amount of the corresponding value from the storage means according to the image processing situation and outputs this to the display means. Therefore, it is possible to reliably change the total remaining power amount according to the state of the image processing.

[0038] In the apparatus according to the eighth aspect, the remaining power of the image processing is provided as a life count value to the character as the display body, and the viewer can know in advance the remaining life of the character that can be controlled by the viewer. it can.

According to the ninth aspect of the present invention, the display body is composed of polygons, and when forming an image of the display body viewed from a predetermined viewpoint, a part of the polygon of the display body in front of the viewpoint is formed. A process for making the image transparent is executed. Then
Even when there are a plurality of display objects overlapping the viewpoint on the three-dimensional coordinates, a part of the polygon in front of the viewpoint is made transparent so that the existence of the polygon on the near side is maintained while the remaining polygons are maintained. The display is displayed on the display means. Therefore, while allowing a plurality of display objects to be freely displayed on the display unit as viewed from a desired viewpoint, the viewer can check the display unit consisting of a plurality of polygons overlapping the viewpoint, and Operation can be performed reliably. This transparency processing is realized by the mesh processing according to the tenth aspect.

According to the apparatus of the eleventh aspect, it is determined whether or not an operation in accordance with a predetermined rule is input to the operation means, as in a rule in a martial arts game, and this determination result is obtained. When it is determined that the operation according to the rule has not been performed, the degree of image processing performed on the display body is suppressed. As a result of this suppression, a part or all of the image processing is invalidated, or processing such as reducing the remaining image processing remaining capacity given to the display object to be operated is realized. Therefore, it is possible to prevent a high evaluation from being given due to the random operation of the operation mechanism.

In the twelfth aspect, the display means includes:
By providing the above-described image processing device, a game game capable of performing effective image processing is provided in achieving a game simulating reality such as a martial art.

Next, the main CPU 201 displays a display to the effect that an opponent character is to be set on the display 3a, so that the player appropriately selects an opponent from these (S306). Thereby, the ability of the character of the opponent is also set.

Here, in step 307, the main CPU 201 also performs a process of making the display data of the viewpoint change and finally part of the character C1 (for example, the head, the main part, the upper arm, etc.) transparent. . This is, first, the main CPU2
01 reads display data from a predetermined address in the ROM 203 and converts it into display data for changing the viewpoint. As a result, initially, as shown in FIG. 6A, a state in which the characters (warriors) C1 and C2 face each other is displayed on the display 3a as viewed from the side. In this case, in FIG. 6, C1 and C2 are characters (warriors), RP is a rope, RG is a ring, LCa and LCb are life counters,
BH is another background. In this embodiment, the fighters C1 and C2 and the rope RP are polygon data, the ring RG is rotational scroll data, and the background BH of a spectator or the like.

Then, it is determined whether or not a battle is possible (S308). This match state is displayed on display 3
a, a character (warrior) C1 is displayed in front of the screen, a part of the warrior C1 such as a head, a waist, and an upper arm is transparently processed, and the character (warrior) C2 of the other party is displayed on the screen. Image processing is performed so that the image is displayed in a state facing the front.

Here, since the player is not in a battle state yet (step 308; NO), the address of the ROM 203 is changed (step 309), and further, a display process for changing the viewpoint is performed (step 307). By repeating this, FIG.
From the state where the warriors C1 and C2 are viewed from the side as shown in (a), the viewpoint is rotated so that the warrior C1 is displayed in front as shown in FIG. 6 (c). When the display in the middle of the rotated display state is displayed, for example, as shown in FIG. 6B, the warriors C1 and C2 facing each other are displayed diagonally.

The image processing involving the change of the viewpoint for displaying the character on the screen, including the transition to FIGS. 6A to 6C, may be performed, for example, as shown in the flowchart of FIG. That is, first, in step S401 of FIG. 5, the main CPU 201 responds to the data read from the ROM 203, and moves the viewpoint C and the warriors C1, C2 and the rope R represented by polygon data with texture.
The movement coordinates of a display object composed of polygons such as P are calculated. The calculation of the movement coordinates is performed using a conventionally well-known affine transformation that can perform translation, rotation conversion, and enlargement (reduction) for each axis by one operation.

Next, in step S402, a three-dimensional polygon data (warrior C2, partly transparent warrior C1, rope RP), which is coordinate-transformed by perspective transformation, is displayed on a screen (screen). Calculate the position data (screen coordinates) and send it to the first VDP 220.

Next, the flow shifts to step S403, in which parameters necessary for rotating or tilting the rotary scroll screen are calculated. Here, “rotation” of the rotation scroll screen is rotation in the scroll coordinate system, and refers to rotation of the entire coordinate system about any one of the three axes. The term “inversion” refers to the rotation of the screen screen itself. Specifically, the ring RG portion on the far side as viewed from the player is reduced, or the ring RG portion on the player side is enlarged or displayed. Or both processes are performed simultaneously.

Next, the main CPU 201 proceeds to step S
At 404, the process waits while judging whether it is a predetermined timing for drawing the polygon data. Then, for example, at a predetermined timing, in step S405, the parameters necessary for the process of rotating and tilting the rotating scroll screen stored in the memory up to that time, that is, the rotating matrix parameters, the moving amount (viewpoint) Are moved to the second VDP 230. Then, in step S206, the main CPU
201 executes a display or drawing command.

The main CPU 201 proceeds to step S
The processing of 401 to S406 is periodically repeated. Main C
The polygon data calculated by PU 201 is the first VDP
Two writing frame buffers 2 written in the VRAM 121 connected to the
22 (or 223), display frame buffer 223
(Or 222), drawing and display are repeated.
That is, the drawing frame buffer 222 (or 223)
While the polygon data texture-mapped is being drawn, the display frame buffer 223 (or 2
The polygon data of 22) is sent to the second VDP 230 and displayed. On the other hand, the second VDP 230 uses the parameters and data transferred from the main CPU 201 to calculate the three-axis rotation of the rotary scroll screen and the rotation (inversion) of the screen screen.

The display screen of the rotary scroll screen is obtained by rotating and converting (including parallel movement) the viewpoint and the screen screen (TV screen) with respect to the center point, and the line of sight passing through the screen screen after the conversion from the viewpoint after the conversion. , A collection of points that intersect the fixed scroll map.

By executing the flowchart of FIG. 5 as described above, the display 3a is displayed on the display 3a as shown in FIG.
A screen is displayed as shown in FIG. 6 (b)... FIG. 6 (c). That is, as shown in FIG. 6A, from the state where the opposing warriors C1 and C2 are viewed from the side, the viewpoint moves sequentially so that the warrior C1 is displayed in front and the warrior C2 is displayed behind. Become. The processing accompanying the viewpoint movement in other scenes is also executed according to the flowchart of FIG. During the movement of the viewpoint, the warriors C1 and C2 are displayed as viewed obliquely as shown in FIG. 6B.
Finally, as shown in FIG. 6 (c), the warrior C1 of the player is displayed in front of the screen and in a transparent state on the display 3a, and the warrior C2 of the opponent is displayed on the front of the screen. It is displayed in a state facing.

As described above, the warrior C1 of the opponent is displayed in front of the screen and in a transparent state.
If 2 is displayed facing the front of the screen, a battle state is entered (step 308; YES), and the process proceeds to the battle state flowchart.

Next, when shifting to the battle state flowchart (step 310) and subsequent steps, first, the main CPU 20
1. In step 310, data of the battle state is stored in the ROM 20.
Read from 3. The main CPU 201 fetches operation data from the sub CPU 204 in step 311 and performs processing of invalid operation degree data in step 312. Here, the invalid operation degree is included in the suppression means described in the claims.

The invalid operation degree in step 312 occurs when, for example, operation data is not input from the joysticks 41am, 41ah or the like in accordance with the rules of the fighting. Factors for increasing the degree of invalid operation include, for example, joysticks 41am, 41ah
, Or keep the joysticks 41am and 41ah in the defense command position for a certain period of time. Factors that reduce the degree of invalid operation include, for example, joystick 4
This is a case where a control command is input from 1am or 41ah or a character movement command is input.

The invalid operation degree is stored in the RAM 20 for example.
In the next battle display data creation image processing, the degree of the image processing is reflected so as to be suppressed. For example, it is conceivable to execute image processing for reflecting the remaining capacity on the display of the remaining capacity of the image processing described below, or for canceling or reducing damage to be given to the opponent even if a punch is hit.

Next, the main CPU 201 executes a process of creating battle display data based on the captured battle data and operation data as described above (step 313).

The battle display data formed in step 313 is, for example, when the warrior C2 of the opponent performs the upper cut, the defense operation of the joysticks 41am, 41ah, etc. of the operation panel 4a is performed to perform the warrior C1.
Is display data for causing the player to perform a defense operation, or to perform an operation of extending the joysticks 41am and 41ah on the operation panel 4a to punch the opponent warrior C2. Thus, when the punch hits, the warrior C2 of the opponent changes the deformation direction of the face (head) of the warrior C2 according to the type of the punch (straight, jab, hook, upper cut, etc.), and the punch strength is increased. By warrior C
The amount of deformation of the face (head) is changed.

When the punch delivered from the opponent's warrior C2 hits the warrior C1, the warrior C1 is moved. Further, in this step 313, the back side of the warrior C1 is also displayed, and
(For example, the head, chest, waist, upper arm, etc.) are displayed in a transparent manner.

Next, the main CPU 201 proceeds to step 3
At step 14, processing relating to the remaining capacity display means is executed. That is, in this step 314, processing is performed so that the remaining capacity of the warriors C1 and C2 can be displayed as an image. This means that, first, the degree of invalid operation obtained in step 312 is
It is reflected as a display for reducing the remaining capacity (life count value). Second, the damage of the fighter (the opponent C2, the player (the player) C1) is calculated, and this is reflected as a display for reducing the remaining power.

When the damage exceeds a predetermined value, a process for bringing down the warrior is executed. By performing the processing in this manner, a full reserve display means for displaying the total reserves of the warriors C1 and C2 and a residual reserve display means for displaying the residual reserves for the total reserves of the warriors C1 and C2 are realized. Is done. Further, a storage means for storing a plurality of remaining powers is provided in a partial area of the RAM 202, and the total remaining power can be sequentially reduced by reading out the total remaining power stored in the storage as needed. it can. And
By performing these image processing, each warrior C1,
The damage received by C2 can be displayed on the display 3a as a life counter, and the damage is accumulated in each round.

The battle display data obtained in step 313 and the data relating to the life counter obtained in step 314 are processed by a display data creation process (step 31).
Passed to 5). In step 315, the main CPU 20
1 executes the flowchart shown in FIG. 5, for example, using the battle display data formed in step 313 and the data on the life counter formed in step 314. Thereby, the warriors C1, C2 are displayed on the display 3a.
Is displayed. And the main CPU 201
Executes a game-out process in step 316.
This calculates the damage of fighters C1 and C2, one of which is 3
When the damage exceeds a predetermined value, as in the case of a multiple down, a command such as a down is issued.

The main CPU 201 determines in step 317 whether or not the game in which the game has been down has ended. If not, the process returns to step 310.

Steps 310 to 31 as described above
By repeating the processing of step 7, polygon warrior C
1, C2 are superimposed and displayed on a ring RG composed of a scroll screen. A rope RP of polygon data is overwritten on the upper end of the ring RG along the edge thereof.

Then, as the game progresses, the warrior C1,
When C2 and the viewpoint move, the movements of the warriors C1 and C2 and the scroll screen and the rope RP composed of the overwritten polygon data at the end of the scroll screen are displayed in synchronization with each other, and both are displayed from the joysticks 41am and 41ah. It is confirmed that the movement matches exactly with the input. As a result, the entire scene accompanying the movement, movement, and change of the viewpoint of the warriors C1 and C2 becomes extremely natural, and a realistic sense of realism can be created.

The main CPU 201 determines in step 3
The detection result is determined in step 17 and, when the
At 18, the game end display process is executed.

Next, the detailed operation of the predetermined steps in the above-mentioned flowchart will be described with reference to FIGS.

[Process for Obtaining Invalid Operation Degree] Next, a process for obtaining the invalid operation degree will be described with reference to FIGS. FIG. 7 is a flowchart for obtaining the invalid operation degree. FIG. 8 shows a graph of the invalid operation degree, in which the horizontal axis represents time and the vertical axis represents invalid operation degree.

The invalid operation degree is a frequency generated when there is no operation input such as the joysticks 41am and 41ah in accordance with the rules of the fighting. This invalid operation degree is obtained when the number of continuous punch command inputs per unit time is equal to or greater than a predetermined value. Further, even when the command input pattern is constant, the degree of invalid operation is increased.

First, the processing when there is no operation input of the joysticks 41am, 41ah, etc. in accordance with the rules of the fighting will be described. This process is executed by shifting to the process of step 312 in FIG. That is, the main CP
U201 determines in step 451 that the main CPU 2
01 determines whether or not operation data can be obtained from the sub CPU 204. Here, when operation data is obtained (step 451; YES), the main CPU 201 determines in step 452 whether the operation data is a defense command. Here, when it is determined that the command is not the defense command (step 452; NO), the main CPU 201 determines in step 453 whether the command is the movement command of the warrior C1. The reason for such determination is that joystick 41am, 41
This is for continuously operating ah and determining whether or not a punch command is continuously input.

If the command is not the movement command of the warrior C1 (step 453; NO), it is determined that the punch is not swinging but a valid punch in accordance with the rules of the fist fight, and the main CPU 201 stores the operation data in the register K3 in step 454. The number of times is added one after another. This register K3
May be provided in a fixed area of the RAM 202, for example. Further, the register K3 accumulates the punch commands due to the continuous operation of the operation panels 4a and 4b.

Next, the main CPU 201 determines whether a fixed time x [second] has elapsed (step 455). This determination is for determining how many punch commands have been input per unit time x [seconds]. If the fixed time x [seconds] has not elapsed (step 455; NO), the process exits this processing routine.

On the other hand, when the predetermined time x [second] has elapsed (step 455; YES), the main CPU 201 reads the data of the register K3 in step 456. The read data is the number y of punches per unit time (x [sec]).

The main CPU 201 sets the register K
3 is 1y or more (step 457; N
O), that is, it is determined that the operation according to the rules of the fighting is not given, and the invalid operation degree is stored in the invalid operation degree storage area provided in a predetermined area of the RAM 202 such that the invalid operation degree is added by one (FIG. 4) Step 312). The value of the invalid operation degree stored in this storage area is, as shown in FIG.
At time x1, the invalid operation degree is increased by one. Then, the main CPU 201 prepares for the next process so as not to affect the previous contents in step 459.
To reset the registers K1 to K3 and exit this processing.

Similarly, the processing of steps 451 to 455 is executed, and at time x2, the processing of steps 456 to 455 is performed.
When the process 7 is executed and 2y shots are obtained, the invalid value is stored in the invalid operation degree storage area as if two more values were added to the previous value (step 458). As shown in FIG. 8, the value of this storage area is the invalid operation degree at time x2 or a value obtained by adding two more. And the main CPU
201 is a register K in step 459 for the next processing.
3 is reset and the process exits.

Further, similarly, steps 451 to 455
Are executed, and at time x3, steps 456 to 4
When 1y shots are obtained by executing the process of 57, the invalid operation degree storage area is stored as if two more were added to the previous value (step 458). As shown in FIG. 8, the value of this storage area becomes a state where one more invalid operation degree is added at time x3. And the main CPU 2
01 is the register K3 in step 459 for the next processing.
Is reset and the process exits.

Similarly, when the processing of steps 451 to 455 is executed and the processing of steps 456 to 457 is executed at time x4 and 1y is obtained, the previous value is further stored in the invalid operation degree storage area. The data are stored as if they were accumulated (step 458). As shown in FIG. 8, the value of this storage area becomes a state in which one more invalid operation degree is added at time x4. Then, the main CPU 201 resets the register K3 in step 459 for the next processing, and exits this processing.

As described above, when there is no operation of the joysticks 41am and 41ah in accordance with the rules of the fighting, the invalid operation degree becomes an even higher value.

Next, a case where the degree of invalid operation is reduced will be described. When a command is input (step 451;
YES), the main CPU 201 determines in step 452 whether the command is a defense command. If it is a defense command (step 452; YES), the main CPU 201 determines in step 460 whether the defense command has been changed to another command or the like (or a neutral position) in a short time. This is to determine whether the operation is in accordance with the rules of the fighting.

When the defense command is changed to another command or the like in a short time (step 460; YES), the main CPU 201 sets the value obtained by subtracting one from the invalid operation degree in the invalid operation degree storage area in step 461. As shown in FIG. 8, the value of this storage area becomes a state where the invalid operation degree decreases by one at time x5. After passing through this processing, the main CPU 201 resets the registers K1 to K3 in step 462 for the next processing.

Next, the operation in the case of a no command will be described. When there is no command input (step 451; N
O) In step 471, the main CPU 201 performs, for example, the processing of the register K1 = K1 + 1. This is an addition performed for detecting a no command during a fixed time. The register K1 is, for example, a RAM
What is provided in the predetermined area 202 may be used.

Next, it is determined whether a predetermined time α (second) has elapsed (step 472). The determination of the time is a determination for detecting that the command is a no command continuously for a certain period. When the fixed time α (second) has not elapsed (step 4
72; NO), exit this process.

On the other hand, when the predetermined time α (second) has elapsed (step 472; YES), the main CPU 201 reads the value of the register K1 in step 473. The value of the register K1 is a value in the case of no command for a fixed time, and if this value is larger than a predetermined value (step 474;
YES), since there is no command for a fixed time, the main C
In step 475, the PU 201 subtracts one invalid operation degree from the invalid operation degree storage area. As a result, the value of this storage area becomes a state where the invalid operation degree is reduced by one at time x7 as shown in FIG. Then, in step 476, the registers K1 to K3 are reset for the next processing.
When the value of the register K1 is smaller than a certain value (step 474; NO), at step 476, each of the registers K1
1 to K3 are reset, and the process exits.

Next, the operation when the defense command is continuously input will be described. In this case, the main CPU 201
Goes through steps 451, 452, and 460, and in step 481, for example, the register K2 = K2 + 1. The register K2 may use a predetermined storage area of the RAM 202, for example. The register K2 is for measuring that the input of the defense command is continued.

Next, the main CPU 201 proceeds to step 4
At 82, it is determined whether a predetermined time has elapsed. This time judgment is
This is for determining that the defense command is continuously input for a certain period of time. If the predetermined time has not elapsed (step 482; NO), the process exits.

On the other hand, when the predetermined time has elapsed (step 482; YES), the main CPU 201 proceeds to step 4
At 83, the value of the register K2 is read. Here, main C
When the value of the register K2 is larger than the predetermined value (step 484; YES), the PU 201 adds one invalid operation degree of the invalid operation degree storage area in step 485 because the protection command is still in the state. I do. As shown in FIG. 8, the value of this storage area is such that the invalid operation degree is increased by one at time x9. After this processing is completed, the registers K1 to K4 are set in step 486 for the subsequent processing.
Reset K3. Leaving the defense command in this way causes the degree of invalid operation to increase.

The operation when the invalid operation degree is reduced will be described. This operates when the movement command of the warrior C1 is input. That is,
When the movement command of the warrior C1 is input (step 453; YES), the main CPU 201 proceeds to step 44.
At 1, the invalid operation degree in the invalid operation degree storage area is decremented by one. Thereafter, the registers K1 to K3 are reset in step 442 for the subsequent processing.

As described above, each of the above steps 451-4
In 92, the operation in accordance with the rules of fist fighting was Joystick 4
It is determined whether or not input has been made from 1am, 41ah or the like.
The invalid operation degree stored in this invalid operation degree storage area is
It is used to suppress the degree of image processing in later processing. For example, the effect is reflected in the process of decreasing the value of the life counter, or even if a punch or the like hits the opponent's warrior C2, its effectiveness is reduced or this effectiveness is denied.

In this manner, the player is urged to perform a reliable operation of the joysticks 41am, 41ah, etc., while providing the player with actual movements in the case of fist fighting, for example. , 41ah and the like can be operated by the player.

[Operations of Polygon Forming Means and Polygon Number Increasing Means] Next, in a normal display state, the face (head) of the warrior C2 is composed of a minimum number of polygons, and this face (head) is When the image is deformed and displayed, the number of polygons for forming the face (head) is increased, and then the face (head) is deformed based on the increased number of polygons. This will be described with reference to FIGS.

First, the main CPU 201 determines in step 5
At 00, it is determined whether or not the flag FLG is 0. This determination is for determining whether or not to perform a table data read process for the transformation process. When reading is performed, a specific processing flowchart is performed. When reading is not performed, normal determination processing is performed.

Since the flag FLG is initially set to 0, the main CPU 201 proceeds to step 501.
Performs image processing for configuring the face (head) of the warrior C2 from a minimum number of polygons. In this image processing, for example, each face of the face (head) of the warrior C2 is composed of one square polygon. Thereby, for example, as shown in FIG. 10A, the face (head) C2f of the warrior C2 is formed into a cube (hexahedron) composed of six polygons. In other words, one polygon is arranged by designating four vertices in three-dimensional coordinates, and each face shares two vertices of the four vertices, so that the face (head) C2f of the warrior C2 becomes a hexahedral polygon. Expressed from a set.

Each pattern (texture) of the front part, the back part, the left and right side parts, the plane part, and the bottom part constituting the various expressions of the actual warrior is photographed in advance by a video camera or the like, or separately formed. , These are stored in ROM 203
To be stored.

Therefore, in step 502, the texture of this expression and the texture of each right side, left side, back, top, etc. are mapped to the polygon of the corresponding address. In this step, it is also determined whether or not texture mapping has been completed for all polygons, in this case, for six surfaces. As a result, FIG.
As shown in (b), the head of the warrior C2 in which the expression has appeared is formed. Here, in order to simplify the expression of the drawing, a case is shown in which the texture (pattern of the face) is attached only to the polygon in front of the head, and the illustration of the texture on other surfaces is omitted.

Next, the main CPU 201 is
Operation data is fetched from 204, and the presence or absence of operation data is determined (step 503). When there is operation data (step 503; YES), the main CPU 201 specifies the content of the punch command (including a defense command) from the direction, strength, speed, and the like of the operation data in step 504. Then, when it is determined from the result of the processing (step 504) that the attack is an attack (step 505; YE).
S), the main CPU 201 determines in step 506 that the warrior C1
Read the coordinates of the punch. Subsequently, the main CPU 201
Reads the coordinates of the head of the opponent's warrior C2 in step 507. It is determined whether these coordinates match (step 508). This determination is equivalent to determining the collision between the fighters C1 and C2.

When these coordinates match (step 5
08; YES), the collision determination of the warriors C1 and C2 is affirmed, and the punch of the warrior C1 (the character on the player side) hits the face of the warrior C2 (the character on the opponent side). Therefore, "1" is set to the flag FLG to shift to the deformation processing (step 50).
9).

The main CPU 201 determines in step 509 whether the punch is the first punch or the second punch. In this embodiment, in order to simplify the description, only two types of punches will be described. Further, in this embodiment, the description will be made assuming that the reflection of the invalid operation degree is processed so as to reduce the effectiveness of the punch. Of course, the value of the life counter may be reduced instead of decreasing the effectiveness of the punch.

First, in the case of the first punch (Step 510; 1P), if the value of the invalid operation degree storage area is equal to or less than a predetermined value in Step 511, the joystick 41a is used.
It is determined that the operation of m, 41ah, etc., does not make a movement that is not in accordance with the rules of the fighting, and the processing shifts to the processing of step 512 and thereafter.

In step 512, for the face (head) C2f of the warrior C2 composed of the minimum number of polygons, the number of polygons constituting each face of this part is increased. As a result, as shown in FIG. 11A, on each face of the face (head) C2f composed of six polygons each assigned a rectangle (quadrilateral), 8 (columns) × 8 It is changed to a plurality of polygons arranged in (row).

Each address of a plurality of polygons on each surface is designated, and these addresses and polygon deformation data are stored in a table for each punch (punch direction, punch type, punch strength). It is assumed that many of these tables are stored in the ROM 203. In step 512 and subsequent steps, from which table the deformation data is to be fetched is specified by the type of punch, the direction of punch, the strength, the type of warrior C, and the like.

Next, the main CPU 201 sets the face (head)
The portion of C2f is composed of a large number of polygons. For each address of each polygon, the polygon deformation data is extracted from the deformation table, and the texture of the facial expression corresponding to this address is deformed. Mapping to the corresponding polygon (step 51)
3). The polygon can be deformed by setting four vertices of the rectangular polygon. In this case, deformation data is obtained as if a large number of polygons each having only four vertices were arranged on each surface of the hexahedron.

Then, the face (head) is obtained based on the deformed data.
It is determined whether mapping has been completed for all polygons of C2f (step 514). When the mapping of the texture to all the polygons is not completed (step 514; NO), the mapping process is continued (steps 513 and 514). When texture mapping is completed for all polygons (step 514;
YES), a normal face is displayed on the hexahedral part as shown in FIG. Then, the main CPU 201
After the life counter data for the warrior C2 is reduced by a predetermined value in step 515, the RO is reduced in step 516.
The read address of M203 and the table read address are updated, and the process exits.

When this routine is entered again, the flag F
Since LG is “1”, the main CPU 201
Reads deformation data from a predetermined address of a predetermined deformation table in step 520. As shown in FIG. 12A, the deformed data includes the addresses P11, P12, P21, P22,.
1, P82, P91, P92, ..., P18, P19, P
28, P29,..., P88, P89, P98, P99.

In step 521, the main CPU 201 selects and modifies the texture of the expression accompanying the punch, and converts the texture into the corresponding addresses P11, P12, P21, P22,..., P81, P8.
2, P91, P92, ..., P18, P19, P28, P
29,..., P88, P89, P98, P99. As a result, as shown in FIG. 11B, the hexahedron constituted by a large number of polygons exhibits a distorted deformation.

It is determined whether mapping of all textures to these addresses has been completed (step 522). When mapping of all textures is completed (step 522; YES), it is determined whether all data of the deformation table has been read (step 522). If not read (step 523; NO), the ROM 20
3 and the read address of the transformation table are updated (step 516).

Each time this routine is passed, the data of the deformation table is read out with the address updated (step 50).
0, S520, S521, S522), the deformed data is obtained one after another, and the distorted face (head) C2f can be displayed. As a result, a distorted head as shown in FIG. 12B and an expression are displayed.

When all the transformation data in the transformation table has been read (step 523; YES), since the transformation of the face (head) C2f has been completed and the original state has been returned, the flag FLG is set to “FLAG”. 0 ”is set, and the routine proceeds to step 516.

On the other hand, if the punch is the first punch (Step 510; 1P) and the invalid operation degree is large (Step 511; YES), the data of the second deformation table having a small deformation amount is read. The process moves to step (step 525).

In step 525, the face (head) C2f of the warrior C2 composed of a minimum number of polygons is increased so as to be composed of a large number of polygons. As a result, as shown in FIG. 11A, each surface of the polygon constituted by the hexahedron is changed to a large number of polygons. Next, in step 526, the texture of the expression is mapped to the deformation data of each polygon. Then, it is determined whether mapping has been completed for all polygons (step 527).
As a result, a normal face is displayed on the hexahedral portion as shown in FIG.

Then, the main CPU 201 reduces the data of the life counter for the warrior C2 by a normal value, updates the read address of the ROM 203 and the read address of the second transformation table in step 516, and exits this processing.

As described above, even in the case of the first punch, which would normally cause serious damage to the warrior C2, if the invalid operation degree is large, the punch is handled as a normal punch.

If the punch is the second punch (Step 510; 2P) and the degree of invalid operation is small (Step 529; YES), Steps 525 to 528, Step 500, Steps 520 to 520 534 is executed. As a result, FIG.
As shown in the figure, each face of the polygon composed of hexahedrons
After the number of polygons has been changed, a normal face is displayed on the hexahedral portion as shown in FIG. 11B. The face (head) C2f of a hexahedron composed of a large number of polygons is distorted, and an expression accompanying the distortion is displayed. In addition,
In this case, since the table is the second deformation table, the degree of deformation is smaller than that in FIG.

In the above processing, only the processing of the warrior C2 has been described. However, as shown in FIG. 13, the head and the chest of the warrior C1 are transparentized on the display 3a, and the warrior C1 is displayed. Are displayed by normal polygon processing. Of course, if your arm is on the warrior C2,
This arm may also be made transparent. One of the perspective conversion processes is a meshing process. In this meshing process, as shown in FIG. 18, for example, it is assumed that a polygon 90 having four vertices is composed of, for example, 9 dots on the XY axes, and the coordinate value of the X axis + the coordinate value of the Y axis = S is an even number. Are drawn, and when the value of S is odd, the drawing is skipped and writing is not performed. In this way, a meshed polygon is obtained.

The display of each of the warriors C1, C2, etc. will be displayed in front of the display 3a in the determination of the priority order of the polygons. Also, since the warrior C2 has the second priority of the polygon, it is displayed behind the warrior C1 and before the rope RP. In addition, since the head and chest of the warrior C1 are mesh-processed, even if the warrior C1 is displayed in front of the screen, the warrior C2 has a shape,
You can see the expression. Also, since the rope RP has the third priority of the polygon, it is displayed on the rearmost side. Further, the ring RG is displayed by rotating scroll. Life counters LCa, LC
Since b is displayed by scrolling, b is always displayed on the left and right sides of the screen of the display 3a. Although not shown, a spectator or the like is displayed as a background BH.

Next, when the punch is the second punch (step 509; 2P) and the invalid operation degree is large (step 529; NO), the read address of the ROM 203 is updated (step 516), and this processing is performed. Through. That is,
When the invalid operation degree is large, it is assumed that an operation in accordance with the rules of the fighting has not been input, and even if a valid punch is delivered, this is invalidated or its power is reduced.

On the other hand, when there is a mismatch at step 508 (step 508; NO), the main CPU 201
In step 531, another coordinate of the opponent warrior C2 is read.

At step 532, the main CPU 201 compares the coordinates of the warrior C2 with the coordinates of the punch of the warrior C1. If they match, it has hit the body of the opponent's warrior C2 (step 532; YES). In this case, no deformation or the like is performed, and the damage is simply treated as being given to the opponent. Then, in step 533, the main CPU 201 reduces the data of the life counter for the warrior C2 by the normal value, and updates the read address of the ROM 203 (step 5).
16), exit this processing.

In the case of defense (step 505;
Defense), the main CPU 201 reads the coordinates of the punch of the opponent warrior C2 in step 541. Also, the main CP
U201 reads the hand coordinates of the warrior C1 in step 542. If they match (step 543; YE)
S), the process is executed assuming that the defense was successful (step 544).

On the other hand, if the two coordinates do not match in defense (step 543; NO), the main CPU 201 reads the coordinates of the other part of the warrior C1 in step 545. When the coordinates of the punch of the warrior C2 of the opponent match the coordinates of the other parts of the warrior C1, the punch of the warrior C2 of the opponent has hit, and in step 547, for example, according to the punching force of the opponent, For example, the fighter C1 is moved to a down state.

Then, in step 548, the main CPU 201 decreases the value of the life counter of the warrior C1 in accordance with the effectiveness of the opponent's punch. And the ROM 20
3 is updated (step 518), and the process exits.

Even if there is no operation data (step 503; NO), if the opponent warrior C2 starts to punch (step 550; YES), step 5 is executed.
The processing shifts to the processing of 41 to 548.

There is no operation data (step 50).
3; NO), when the opponent's warrior C2 does not advance the punch (step 550; YES), performs no processing, updates the read address of the ROM 203 (step 518), and exits this processing.

By processing each of the processing steps as described above, usually, the processing load is reduced by displaying with a small number of polygons, and the punch of the warrior C1 is replaced by the warrior C2.
When it is desired to change the expression on the face or the like, a polygon composed of hexahedrons is composed of a large number of polygons and these are deformed. Thereby, an interesting game environment can be provided. Further, in the case of normal display, since the face (head) C2f is constituted by a hexahedron, when a punch is not hit, a minimum polygon is required.

In the above embodiment, the addresses of the respective polygons are specified, and from the table of these addresses and the polygon deformation data, the deformation data corresponding to the type of punch is obtained. And so on, but of course, the deformation data may be obtained by calculation.

[Operation of Image Processing Surplus Display Means] Next, the life counters LCa and LCb of the fighters C1 and C2 (FIG. 13)
14) and the data processing required for this display will be described with reference to FIGS. FIG. 14 is a flowchart of the image processing reserve display process.
15 to 17 show life counters LCa and LCb.
FIG. 9 is an explanatory diagram showing an example of the display state of FIG. 15 to 17, only the life counter LCa is displayed. Of course, the life counter LCb is also displayed. For simplicity of description, only the life counter LCa is shown and described in FIGS. FIG.
5 to 17, the life counter LCa includes a meter M indicating the total remaining power, a face F as a means for displaying the remaining remaining power with respect to the total remaining power, and a number (“1”, “2”, "3") and a display which blinks or lights on these numbers.

First, when the game is started, the total remaining capacity for the warrior C1 is stored in the storage area 202C1, so that in the step 601 this storage area 202
Read the data from C1.

Next, the warrior C1 gets a punch by the processing of the step 313 (as the image processing progresses).
When the data relating to the life counter decreases, the remaining remaining capacity is reduced in step 602 based on this value.

In step 603, display data is created from the data of the meter M in the previous step and the data of the remaining power. As a result, data indicating the meter M is formed, and data on the remaining surplus with respect to the total surplus is formed. At first, since the data of the meter M and the data of the remaining power are the same, the life counter LCa displays the meter M and the face F at the same position (game start (time t1) in FIG. 15).

Then, in step 604, the relationship between the face F (existing remaining power) and the meter M (total remaining power) is determined (step 604).

If the face F (existing remaining capacity) does not reach the bottom of the meter M (full remaining capacity) (step 604; NO),
Exit this process. Therefore, it is simply displayed so that the remaining surplus amount decreases. That is, step 601
By repeating the processes of to 604, the display is such that only the face F is simply lowered (time t1, t2 in FIG. 15).

When the face F (existing remaining capacity) reaches the bottom of the meter M (full remaining capacity) (step 604; YES),
In step 605, it is determined whether the down is the third down. If it is not the third down (step 605; NO), the number "1" portion of the life counter LCa is blinked (step 606). As a result, the warrior C1 is down 1st. The life counter LCa is shown in FIG.
As shown in 5 (t3), the first down is performed, the upper part of the number “1” is displayed in a blinking state, and the face F is displayed at the bottom.

Before the referee count is entered, step 6
At 07, the value of the storage area 202C1 is reduced by a certain amount. Also, in this step, the storage area 202C1
And the data of the knockout avoidance point (KO) is created or the corresponding data is read from the memory, and the data for displaying the position of the face F spoken from the meter M is formed. By displaying this data, the face F is displayed at a position away from the meter M, as shown in FIG. Also, as shown in the figure, point A is displayed on meter M, and point B is displayed as indicated by arrow Y. This B point is at time t
It is shorter than at 1 (the meter M is displayed shorter). Then, the C point is set or determined by software, and a knockout avoidance point (KO) is displayed.

Further, the physical strength of the warrior C1 is calculated in step 608.
At a predetermined recovery condition. The count end condition is a case where the face F reaches the point A within the count “10”. The C point is a motion compulsory generation point. Therefore, the remaining remaining energy is recovered according to the recovery of the physical strength (step 608). Further, a display for raising the face F is displayed (step 608). This causes the face F of the life counter LCa to rise as shown by the arrow Y, as shown in FIG. And B at 9 counts
When the player enters the area of the points or the points A and B (step 609), an instruction to start the processing of the next round is input again (step 610). If the game does not enter the area of the B point or the AB points at 9 counts (step 609; NO), the processing is, for example, a game over (step 611).

In the second round, the data of the meter M is read in step 601. Step 60
In step 2, the remaining capacity is reduced. When these data are displayed in step 603, the face 3 is displayed on the display 3a in a state where the face F is lowered in the direction of the arrow Y, as shown in FIG.

When the control passes steps 604 and 605 and there is no remaining remaining power, the life counter LCa falls down for the second time as shown in FIG. Is displayed in a blinking state, and the face F is displayed at the lowest position (step 606).

Before entering the referee count, step 6
At 07, the total amount of the life counter LCa is reduced, a knockout avoidance point (KO) is output, and the face F
Change the position of. Thus, as shown in FIG. 16 (t8), the face F is displayed at a distant position.

When the physical strength of the warrior C1 is restored, a display for raising the face F is displayed (step 608).
Thus, the face F of the life counter LCa is raised as shown by the arrow Y, as shown in FIG. Then, after recovery (step 609), a command to enter the next round is issued again (step 610).

In the third round, step 6 is performed again.
The processing of 01 to 604 is performed. Thereby, the face F is displayed on the display 3a in a state where the face F is lowered in the direction of the arrow Y as shown in FIG. 17 (t10).

When the remaining amount runs out (step 6)
04), the life counter LCa falls down three times as shown in FIG. 17 (t11), the number “3” is displayed in a blinking state, and the face F is positioned at the bottom. Displayed, a game over display is performed in step 612. When there is remaining power, the process goes through this process without performing any process.

When the processing steps are executed as described above, the processing of the image processing available display means is performed. This processing is a display processing of the total remaining amount by the total remaining amount display means,
The remaining surplus amount display means displays the remaining surplus amount with respect to the total surplus amount, and the remaining surplus changing means sequentially reduces the total surplus as the image processing progresses.

Since the display processing of the life counter LCa is as described above, it is possible to enjoy a realistic game development with respect to the damage of each of the warriors C1 and C2.
