In particular, the present invention relates to a technique for operating an object arranged in a virtual three-dimensional space.

[0002]

2. Description of the Related Art In a pachinko machine which is this kind of game machine,
A game state that is advantageous for a player who can obtain a large number of pachinko balls and a game state that is disadvantageous for a player who consumes pachinko balls are generated. In order to make the interest of the game permanent, a realistic display mode is displayed according to each game state. As a display mode, a player can feel a sense of realism by changing, for example, enlarging or reducing or moving a pattern, which is a two-dimensional image drawn using a perspective or the like, on a display screen. A possible display mode is realized.

[0003]

However, the conventional pachinko machines described above have the following problems. In a conventional pachinko machine, a display form in which a symbol, which is a two-dimensional image, is simply enlarged or reduced and moved, is displayed. Had occurred. Therefore,
2. Description of the Related Art In recent years, attempts have been made to realize a realistic display mode by changing the pattern of a three-dimensional image on a display screen by changing an object formed of polygons in a virtual three-dimensional coordinate space. Specifically, an object is arranged in the virtual three-dimensional space, and the object is changed. A display image showing a state in which the object fluctuates in the virtual three-dimensional space is generated based on a given viewpoint,
By sequentially displaying the display images on the monitor, the realistic fluctuation of the design is displayed.

However, in the case where the pattern displays a mollusk such as an octopus, a squid, a jellyfish, and a sea anemone, for example, the legs, arms, and tentacles of the mollusk are expressed in a wave-like motion. Since the arms and the like are composed of a plurality of component objects, and the joints of the respective component objects are used as joints, so-called multi-joint processing for displacing each of the component objects is performed. There is a problem that the processing load on the gaming machine increases. Specifically, for example, an object for displaying an octopus is constituted by a head part object and an arm part object,
When each arm is composed of three part objects, one head + 24 arms (3 × 8) = 25 parts objects in total are required as the entire octopus object. In order to move the arm, it is necessary to perform control processing on 24 component objects. For this reason, in a gaming machine equipped with hardware that can only control a limited number of objects, for example, the number of octopus symbols that can be displayed at the same time is reduced, for example, the number of other symbols displayed with the octopus is reduced, for example, Since it is necessary to keep the octopus's arm from moving, only a display mode with a poor sense of reality can be displayed, and a problem arises in that the interest of the player playing the gaming machine cannot be maintained.

[0005] The present invention has been made in view of such circumstances, and it is possible to relatively reduce the processing load, display a realistic display mode, and make the player's interest last.

A counter 14, a start-up start sensor 12 for detecting a pachinko ball entering at the starting port 2c (see FIG. 1), and a prize detecting sensor 11 for detecting pachinko ball entering at the prize opening 2b (see FIG. 1). , Grand Prize Winner 2
An open / close solenoid 13 that opens and closes d (see FIG. 1) and an I / F (interface) 15 that is connected to an I / F (interface) 17 of the image display device 7 so that information can be distributed.
It is configured with such as. The control base 1 executes various events such as supplying a predetermined amount of pachinko balls and operating lamps and speakers (not shown) based on the detection of the ball detection sensors at the winning opening 2b and the starting opening 2c. Things. Further, the control base 1 sends various commands for instructing a display mode according to the game state to the I / F.
15 to the image display device 7.

Specifically, the processing performed by the control board 1 will be described in detail with reference to the flowchart shown in FIG. Step S1 (Detection of Incoming Ball) The player drives the pachinko ball into the gaming board 2 with the rotary handle 5, and starts the pachinko game. Gaming board 2
A portion of the pachinko balls hit inside are guided to near the center of the board and enter the starting port 2c. When the pachinko ball enters the start port 2c, the start start sensor 12 that detects the ball that has entered the start port 2c outputs a start start signal to the main control section 16c.
And the winning detection sensor 11 provided in the starting port 2c sends a winning signal to the main controller 16. In this embodiment, the start start sensor 12 and the winning detection sensor 1
1 is used together by the same sensor. Also, when a pachinko ball enters the winning opening 2b, each winning opening 2b
The winning detection sensor 11 sends a winning signal to the main control unit 16.

Step S2 (Supply pachinko balls) When the main control unit 16 detects a winning signal from the winning detection sensor 11, it activates a pachinko ball supplying mechanism (not shown) to supply a predetermined number of pachinko balls to the ball supply port 4a. To the upper tray 4

Step S3 (big hit lottery) When the main control unit 16 detects the start start signal from the start start sensor 12, the main controller 16 reads the output value of the counter 14 and performs a big hit lottery. In the jackpot lottery, if the output value of the counter 14 is a predetermined value, a "big hit" is generated. On the other hand, if the output value of the counter 14 is other than the predetermined value, the normal game state of “losing” is continued.

Step S4 (Transmit Command) The main control unit 16 determines a display mode according to a normal game state or a specific game state, and displays a command according to the display mode via the I / F 15 in an image display. Transmit to the device 7.
The command is an instruction for causing the image display device 7 to execute a predetermined display program, and a display pattern corresponding to a game state is displayed on the display screen 6a by executing the display program. For example, in the case of a jackpot, the main control unit 16
Sends a command to start a given reach,
After a lapse of a predetermined time, a command indicating the type of the jackpot identification symbol to be stopped at the final stage of the reach is transmitted. Thereby, the display screen 6a of the image display device 7 includes
After the command displays the type of reach indicated,
Further, it is displayed so as to stop at the jackpot identification symbol of the type designated by the command. At this time, the main control unit 16
After the stop of the jackpot identification symbol is displayed on the display screen 6a, the opening signal is given to the open / close solenoid 13 to open the big winning opening 2d, so that the player can acquire a large number of pachinko balls. I do. Further, in this game state, the control base 1 has, for example, about 10 balls with a special winning opening 2.
The winning of d is regarded as one round, and each time the round ends, a command instructing the end of the round or the start of the next round is transmitted to the image display device 7.
Thereby, the display mode of a different pattern is displayed on the display screen 6a for each round. On the other hand, in the case of a loss, a command for instructing the type of the identification symbol of the loss to be stopped at the final stage of the reach, or a command for stopping the identification symbol fluctuating during the normal game state at the identification symbol of the loss. The image is transmitted to the image display device 7. As a result, the display screen 6a is displayed so as to stop at the lost symbol after the reach is displayed, or to stop at the lost symbol after the normal fluctuation.

Step S5 (New ball detection?) The main controller 16 waits until it detects the presence or absence of a new start signal from the start sensor 12 (new ball). If there is no new start start signal, this process is terminated and the process stands by until a new start start signal is detected. The control base 1 that executes the above-described steps S1 to S5 corresponds to a so-called game state generating means. Note that the start start sensor 12 detects the entry of a pachinko ball during the change of the identification symbol (reach, normal variation, etc.), and stores the number of the entered pachinko balls, and the above-described holding lamp, which has not been described, lights up. If so, the lighting of the holding lamp is detected as a new start start signal. If there is a new start start signal, steps S2 to S4 are repeated.

This display mode is one display mode of the reach in the pachinko machine, and as shown in FIG. 5, each of an upper area 61, a middle area 62, and a lower area 63 vertically dividing the display screen 6a into three. An identification symbol is displayed in the area. Although not shown here, at the time of normal rotation, the displayed identification symbols in the regions 61 to 63 move at low speed or high speed in the horizontal direction, respectively. When the reach occurs, as shown in FIG. 5, the identification symbols moving in the upper region 61 and the lower region 63 are stopped so as to be aligned in the same type in the oblique direction (or the vertical direction) of the display screen 6a, Only the identification symbol in the middle area 62 is displayed so as to continue moving in the horizontal direction. Hereinafter, this display mode will be specifically described.

Specifically, as shown in FIGS. 5A and 5B, an identification symbol 61a which is an image of an octopus with a symbol number "1" is provided on the right side of an upper area 61 of the display screen 6a.

Step T 1 (Command Grasp) The I / F 17 sequentially receives commands sent from the control board 1 and sequentially passes the commands to the three-dimensional image processing unit 19. The three-dimensional image processing unit 19 stores the command in a command buffer (not shown) provided in the work RAM 23. Further, the three-dimensional image processing unit 19 reads the command stored in the command buffer every time an interrupt process is performed from the liquid crystal monitor 6, executes the program in the program ROM 22 corresponding to the command, and executes the program for one screen. Display images are sequentially generated. By executing the program, the following steps are executed in the three-dimensional image processing unit 19. The above-described interrupt processing is performed in synchronization with, for example, a vertical scanning signal every 1/30 second or 1/60 second of the liquid crystal monitor 6.

Step T2 (set viewpoint in world coordinate system) The three-dimensional image processing unit 19 sets a world coordinate system corresponding to a virtual three-dimensional space for arranging a plurality of objects. Next, a viewpoint for displaying the state in the world coordinate system on the display screen 6a of the liquid crystal monitor 6 is set in the world coordinate system. The viewpoint is a reference point of a coordinate system using a line of sight as the z-axis so as to face a predetermined direction in the world coordinate system, for example, the direction of the space in which the object is set. Specifically, the three-dimensional image processing unit 19 shown in FIG. 8 based on the coordinate values in the world coordinate system for arranging the viewpoint derived by the program and the rotation angle for determining the direction of the line of sight. As described above, the viewpoint S in which the line of sight (the z-axis direction) faces, for example, the direction in which each object described later is arranged.
P is set to the arrangement position P ₀ (P _0X, P _0Y, P _0Z ). The state in the world coordinate system in the direction in which the line of sight from the viewpoint SP is directed is displayed on the display screen 6a of the liquid crystal monitor 6. In this embodiment, a viewpoint SP fixed at a predetermined arrangement position in the world coordinate system will be described. However, the viewpoint SP of the viewpoint SP is determined based on a coordinate value and a rotation angle such that the value changes for each interruption process. It is also possible to set the viewpoint SP such that the position and the line of sight are displaced.

The image is formed in a three-dimensional shape corresponding to the shape of the image.
In this embodiment, each object is set based on the viewpoint SP.
Because the objects B1 to B4 are arranged, the arrangement position of the viewpoint SP
Even if the position or gaze direction is displaced,

Next, interrupt processing coordinate values of the X-axis component of the object B3, the arrangement of the B4 position P _5, P ₆ for displaying identification symbols 62a, 62b that are displayed in the middle area 62 of the display screen 6a Are sequentially updated (subtraction or addition of coordinate values) for each of the positions P of the objects B3 and B4.
_5, thereby gradually moving the position of the P ₆ in the lateral direction (indicated by the arrow in FIG. 8). When a predetermined time has elapsed, the display screen 6
Since the identification symbol for displaying the image of the octopus moves and appears in a, the arrangement position of the object B1 for displaying the identification symbol of the octopus is similarly sequentially updated and moved. The process of moving the object B1 is as follows.
This corresponds to the function of the object moving means in the present invention. In addition, this movement is not limited to the horizontal direction, and X,
By appropriately updating the coordinate values of Y and Z, the present invention can be similarly applied to a predetermined direction, for example, from the vertical, oblique, and back to the front.

Further, the three-dimensional image processing section 19 changes the form of the objects B1 to B4. More specifically, an object B2 for displaying a harris bomb and an object B4 for displaying a fish are each composed of two part objects that are divided into front and rear, and each part object is connected at a predetermined connection point. Are linked. The three-dimensional image processing unit 19 swings the front and rear part objects right and left around the connection point, and changes the objects B2 and B4 as if they swam their tail fins and swim. Also, an object B3 for displaying a seal
Is composed of three part objects that are divided into front and rear parts, and each part object is connected at each connection point. The three-dimensional image processing unit 19 swings each of the component objects up and down around the connection point so that the seal moves while swinging its head and tail.

Here, the three-dimensional image processing unit 19
The object B1 is also changed in order to display the octopus movement as shown in (a) to (h). The processing performed by the three-dimensional image processing unit 19 at this time is described with reference to FIGS.
1 will be described.

As shown in FIG. 9, the head part object B1 for displaying the head of the octopus is stored in the character storage section 18.
object for displaying a and the whole octopus that is constructed by connecting the origin and the arm portion part object B1b for displaying the 8-arm portion of the octopus eg local coordinate system as a connecting point C ₀ B1 is stored. The arm part object B1b of this object B1 is
Horizontal direction around the connecting point C ₀ is composed of a plurality of lines for example eight arms L1~L8 are formed radially at regular angle, for example, 45 degrees (xy plane), each arm L1
L8 are formed in different forms in a series of movements of the octopus arm. Each arm L1~L8 the extending portion in the present invention, the connecting point C ₀ is the reference point of the object in the present invention correspond respectively.

The three-dimensional image processing unit 19
Read 1 from the character storage unit within 18, each on the above-mentioned arrangement position P _1, P ₄ of the world coordinate system, whenever there is an interruption process of a predetermined number of times, the arm portion of the object B1 disposed within the world coordinate system Part object B
The 1b around the connecting point C ₀ is rotated by a predetermined angle, for example, 45 degrees, changing the object B1. Specifically, FIG. 1 is a plan view of the arm part object B1b.
0 and as shown in FIG. 11 (a) is a side view, whenever there is an interruption process of a predetermined number of times, is rotated by 45 degrees in a predetermined direction, for example clockwise each arm L1~L8 about the connecting point C ₀ Then, the rear arm in the rotation direction is almost moved to the position of the front arm in the rotation direction. Thus, by the same angle as the angle of the arm L1~L8 are formed of the arm portion part object B1b, since the center by rotating the Udebu component object B1b the coupling point C _0, arrows shown in FIG. 10 50
Focusing on only the arm AL at the position A from the direction of FIG.
As shown in FIGS. 1 (b) to 1 (i), each time the arm is rotated by 45 degrees, the arm at the position A operates so as to wave up and down in the z-axis direction. In the present embodiment, the case where the octopus arm (extending portion) formed every 45 degrees is rotated by 45 degrees has been described, but the present invention is not limited to this.
What is necessary is just to rotate the extending portions provided at equal angles within the range of 360 degrees by the equal angle.
Further, the component object B1b corresponds to an object provided with the extension part of the present invention. In step T3,
The objects B1 to B4 that fluctuate as described above are set in the world coordinate system.

Step T4 (Deformation correction of viewpoint coordinate system) The three-dimensional image processing unit 19 uses the coordinate values of the objects B1 to B3 arranged in the world coordinate system as the viewpoint coordinate system using the viewpoint SP as a reference, that is, the origin. To the coordinate values of
Here, since the aspect ratio of the display image generated in the frame memory by the rendering processing unit 27 is 3: 4, when the display image is displayed on the display screen 6a having the aspect ratio of 9:16, the display image is extended. There is an adverse effect that the image becomes a blurred image. Therefore, by modifying the viewpoint coordinate system in accordance with the aspect ratio of the display image and the aspect ratio of the display screen, each design or the like arranged in the viewpoint coordinate system is transformed.

Specifically, the three-dimensional image processing section 19 calculates a deformation correction value for correcting the deformation of the viewpoint coordinate system.
This deformation correction value is a magnification value for enlarging or reducing the vertical width or the horizontal width of each of the objects B1 to B3.
Assuming that the aspect ratio of the display screen 6a is A: B and the aspect ratio of the display image is a: b, the deformation correction value can be calculated by the following equation (1). Note that the deformation correction value calculated by the following equation (1) is a magnification for deforming and correcting the width of an object or the like when the width is deformed according to the screen based on the vertical magnification of the display image. The value is a magnification value for correcting the vertical width of each of the objects B1 to B3 when the vertical width of the display image is deformed according to the screen based on the horizontal magnification of the display image.

(A × b) ÷ (a × B) (1)

The aspect ratio of the display image generated in the frame memory is 3: 4, and the aspect ratio of the display screen 6a is 9: 1.
In the case of 6, the display image is displayed on the display screen 6a with the aspect ratio of 9:16, and the width of the display image is 4/3.
It is displayed as if it were enlarged twice. At this time, the width of the symbols of the objects B1 to B3 included in the display image is also 4 /
It is enlarged three times. Here, by substituting each value of the aspect ratio of the display image and the display screen 6a into the equation (1), the width of each of the objects B1 to B3 is increased to three quarters (hereinafter, “3 /
A magnification correction value of the magnification value for reducing the magnification to “4 times” is calculated. Further, the three-dimensional image processing unit 19 reduces the horizontal direction (x-axis direction) of the viewpoint coordinate system to 3/4 times based on the deformation correction value. As a result, each of the objects B1 to B3 is reduced to 3/4 times in the x-axis direction of the viewpoint coordinate system. In this embodiment, the viewpoint coordinate system is deformed and corrected in step T4. However, the processing after step T4 can be performed without performing deformation correction.

Step T5 (projection on projection plane) The three-dimensional image processing unit 19
A projection plane TM perpendicular to the z-axis, which is the line of sight of the viewpoint coordinate system, is set between. Since the projection plane TM is perpendicular to the z-axis of the viewpoint coordinate system and has a fixed z value,
On the projection plane TM, it can be handled as a two-dimensional coordinate system. The projection plane TM has an area corresponding to a frame memory provided in the image storage unit 20.

Further, the three-dimensional image processing section 19 parallel projects each of the objects B1 to B3 on the projection plane TM. Thereby, each vertex of each polygon constituting each of the objects B1 to B3 is projected as it is so as to move in parallel to the projection plane TM, and the three-dimensional coordinate values of each vertex are two-dimensional coordinates on the projection plane TM. Converted to a value. The three-dimensional image processing unit 19 obtains projection information of each object in the world coordinate system when the projection of all objects ends. In the present embodiment, the objects B1 to B3 are parallel-projected in order to easily recognize the identification symbol for the player to grasp. However, for example, perspective projection may be performed to express a more three-dimensional effect. . Further, in this embodiment, the auxiliary symbol other than the identification symbol is not described, but it is preferable that the auxiliary symbol is perspectively projected to express a three-dimensional effect.

Step T6 (Generation of Display Image) First, the three-dimensional image processing unit 19
Is read out, and the background image is drawn in a frame memory in the image storage unit 20. This background image is an image that displays, for example, the state of the sea and the sea floor as shown in FIG.

Next, the three-dimensional image processing section 19 stores an address in the frame memory of the image storage section 20 corresponding to the coordinate value of each vertex of each polygon of each of the objects B1 to B3 included in the projection information, that is, the frame memory. The position of each polygon of each of the objects B1 to B3 is obtained. Then, the texture read from the character storage unit 18 is drawn on each polygon. Thereby, the images of the objects B1 to B3, that is, the identification patterns 61a to 61b are displayed on the background image.
A display image on which 63b is superimposed is generated in the frame memory. Step T6 corresponds to the function of the display image generating means in the present invention.

Step T7 (Display) The three-dimensional image processing section 19 outputs the display image generated in the frame memory to the liquid crystal monitor 6 via the video output section 30. The liquid crystal monitor 6 sequentially displays a display image having an aspect ratio of 3: 4 sent from the three-dimensional image processing unit 19 for each interruption process in accordance with a display screen 6a having an aspect ratio of 9:16. As a result, the display modes shown in FIGS. 5A to 5C are displayed.

In the above-mentioned pachinko machine, the arm part object B1b of the object B1 for displaying the octopus is simply rotated in order to make the octopus displayed at the time of the reach reach a wavy operation. It is possible to reduce the processing load of the pachinko machine such as the geometry calculation processing. In addition, the display mode having a sense of presence due to the waving motion of the octopus arm can make the player who plays the pachinko machine have a lasting interest.

In the above-described embodiment, the liquid crystal monitor has been described.
A T monitor or an LED monitor can be used.

In the above-described embodiment, the pachinko machine has been described as a gaming machine. However, the present invention is not limited to this, and may be modified to a gaming machine such as a slot machine or a coin game machine. it can.

Further, in the above-described embodiment, the display mode in which the octopus operates at the time of the reach is described. However, the present invention is not limited to the display mode at the time of the reach. It is also possible to appropriately apply the display mode at the time or at the time of the demonstration.

[0066]

As is apparent from the above description, according to the present invention, an object provided with a plurality of extending portions extending around the reference point is rotated around the reference point in a predetermined rotation direction. Let it. At this time, since the rear extension in the rotation direction is rotated so as to almost move to the position of the front extension in the rotation direction, each extension of the object displayed on the display screen is rotated. Instead of being displayed as it is, it can be displayed so that its form changes in a stopped state. Therefore, the processing load on the gaming machine can be reduced as compared with the conventional case in which, for example, a plurality of polygons and objects constituting the extension are controlled and the operation of each extension is displayed. In addition, it is possible to display a display mode with a sense of realism, and to make the player's interest more permanent.
