Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer game machine for displaying a die image.

[0002]

2. Description of the Related Art Most game machines, such as mahjong game machines, which display dice images on the screen, operate the dice by push button switches.

[0003]

However, the operation of pushing the push button switch is far from the feeling of "rolling the dice" and cannot be realized. Recently, a game machine that can obtain the same operational feeling as a so-called "experience game" is gaining popularity, and there are strong demands from game players. This is not an exception for game machines that display dice on the screen, and it is still desirable to obtain the operational feeling of "rolling the dice", which also adds value to the game machines.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a dice display device for a computer game machine, which can give a pseudo feeling of "rolling a dice". I am trying.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, the dice display device for a computer game machine according to claim 1 detects a trackball for operating a dice, and a detection unit for detecting an operation amount and an operation direction of the operated trackball. A display position calculation unit that calculates the rolling angle and rolling speed of the die from the operation amount and the operating direction, and obtains the display position of the die from the rolling angle and rolling speed for each preset time interval, and a plurality of In the image database, an image database that stores in advance an image pattern representing the rolling pattern of the dice in the rolling angle of each die, and an image pattern of the rolling pattern of the die based on the calculated rolling angle of the dice. A display control unit for selecting the image pattern and outputting the image pattern to the calculated display position, and a display for displaying the image of the dice Characterized by comprising a stage.

Further, in the apparatus according to the second aspect, the display position calculating section is provided with a function of adding a minute angle calculated by using a random number to the calculated rolling angle of the die.

[0007]

The function of the present invention is as follows. In the device according to claim 1, the rolling angle and rolling speed of the die are calculated based on the operation amount and the operating direction of the trackball that has been operated, and the rolling angle and rolling speed of the die are calculated for each set time. Obtain the display position. Then, an image pattern corresponding to the rolling angle of the dice is selected from the image database and output to the display position. By repeating this process continuously, the rolling mode of the dice according to the operation amount and the operation direction of the trackball is displayed on the display means. As is well known, the movement of the hand when operating the trackball is a movement common to the action of “swinging the dice”, and an actual feeling of “swinging the dice” is artificially obtained by operating the trackball. Then, since the rolling mode of the dice is displayed based on the operation amount and the operating direction of the trackball, it is possible to visually feel that "the dice are swung".

Further, in the apparatus according to the second aspect, since a minute angle obtained by using a random number is added to the calculated rolling angle of the die, the rolling direction of the die is the same even if the operation direction of the trackball is the same. Changes slightly each time. As is well known, since the actual die is a regular hexahedron, the rolling direction of the dice is not constant but changes each time even if the dicing direction is the same. With this device, such a rolling condition of the dice is produced as in the actual situation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a three-dimensional view showing the appearance of the game machine in this embodiment. This game machine is a mechanized version of "Clap Game", which is a representative game of casinos, along with poker, blackjack, and roulette. In the "clap game", bet a coin at a desired position on a clap table on which a certain pattern is printed.
This is a game in which the result is divided according to the total number of "eyes" of the dice rolled and the betting rate according to the bet position. The person who rolls the dice (called the shooter) is changed by rotation, and the participants of the game are in charge of each.

In this game machine, two CRT displays 1 for displaying an image having the same design as a crap table and a dice formed by computer graphics are arranged in the center, and six players are arranged around the CRT display 1. Game console 3 configured by deploying operation console 2
And a lighting table 4 standing upright on the game table 3 with four cylinders. Although not shown, the lighting table 4 is provided with a spotlight for illuminating a specific player. Each operation console 2 is provided with a trackball 5 for operating a dice, a BET button 6 for betting coins, and a payout opening for paying out a payout coin (not shown). When,
It is equipped with speakers that emit sound effects.

The trackball 5 is a rotating ball 7 with an illumination lamp (not shown) operated by a player of the game, as shown in FIG.
The rotary shaft 8X provided in the horizontal direction (X-axis direction) that rotates together with the rotary shaft 8Y and the rotary shaft 8Y provided in the vertical direction (Y-axis direction). Detection units 9X and 9Y for detecting the rotation speed and the rotation direction are provided. As shown in FIG. 3, the detectors 9X and 9Y form slits 12 and 13 which are out of phase with each other along the circumferential direction of the disk 10 attached to the rotary shafts 8X and 8Y. The light emitting diode 14
And photodiodes D1 and D2, and an X-counter 30 and a Y-counter 31 for counting the number of output signals from the photodiodes D1 and D2.

The X-counter 30 and the Y-counter 31 are connected to the CPU 15 built in each operation unit 2, and the BET button 6 and the speaker are connected to the CPU 15 although they are not shown. Has been done. The CPU 15 is provided inside each operation unit 2 and is connected to the main CPU via the communication path 16.
Connected to PU17.

The following components are connected to the main CPU 17. That is, a ROM 18 containing a game program, a RAM 19 for storing various data calculated during the game, an image database 20 for registering image patterns of dice described later, and a display corresponding to each of the two CRT displays 1. Memory 21,22, decimal 10
A random number generator 23 that generates a random number composed of digits.
The random number generator 23 outputs the random number Xi as "Xi ← [aX (i-1) +
C] mod m ″ is calculated by the general formula. In this formula, the symbols a, C, and m are arbitrarily defined constants, and the symbol X (i-1) is the random number calculated immediately before, and the constant a , C, m
Is appropriately determined so that the calculated random number Xi has a different value every time and all the random number values that can be calculated are calculated evenly.

Next, the effect display of dice on the above-mentioned game machine will be described. First, the overall flow of the game will be described based on the flowchart of FIG. In step S1, a shooter replacement flag is set as an initial setting. In step S2, BET is detected. Participants in this game place bets on desired positions by operating the trackball 5 and pressing the BET button 6 after inserting the medals into the game machine. This operation is called BET, and by detecting the BET, which operation console 2 participates in the game is determined.

When the BET is detected, in step S3,
A timer of "7 to 20 seconds" is started, BETs are further accepted during this period (steps S4 and S5), and participants in the game are accepted. Once the game participants have been decided, the shooter (Trackball 5
The person who rolls the dice is operated. When the shooter is determined, the shooter is illuminated with a spotlight provided on the lighting table 4, and the trackball 5 provided on the operation unit 2 of the shooter is lit to notify that the shooter has been selected. .

In step S7, the tracker 5 rolls according to the rotating direction and rotating speed of the trackball 5 operated by the shooter 2.
The state of each die is displayed on the CRT display 1.
The effect display process of the dice will be described later. In step S8, the number of coins to be paid to each player is calculated from the total number of two dice and the bet rate based on the BET position on the clap table. In step S9, it is determined whether or not the next shooter needs to be replaced based on the total number of the two dice according to a certain rule (which is not important here and thus omitted). If necessary, set a flag for shooter replacement in step S10 and set in step S
When it is determined that the shooter will continue to cast, the process proceeds to step S11 without setting the flag.

In step S11, it is determined whether or not there is a player who has won a great win from the calculated number of payout coins and the preset number of reference coins. If there is a big winner, the process proceeds to step S12, and the big winner is illuminated with a spotlight mounted on the lighting table 4 to produce the big winner. In step S13, the payout coin is settled for the winner.
As this settlement method, the number of payout coins is displayed on a digital display section (not shown) provided on the operation console, and when the player quits the game, the coins are paid out from the payout opening of the game machine, or Each time, the payout coins are paid out from the payout opening. Then, the invalid BET is cleared. In step S14, the spotlight is turned off and the sound effect is turned off, and the process returns to step S2, and the BET is placed.
Enter the waiting state.

Next, the effect display process of the dice in step S7 will be described with reference to the flowchart of FIG. This process is a process in the main CPU 17. In step S71, two dice d and D are placed on the CRT display 1 corresponding to the position of the operation portion 2 of the selected shooter.
The image (see FIG. 6) is displayed. FIG. 6 shows a simplified top view of the game console 3 of FIG. 1, and only one operation unit 2 is shown for convenience.

The image of the dice displayed here is read from the image database 20 shown in FIG. 3 and transferred to the display memory 21 or 22. In the image database 20, (1) image patterns (6 ways) corresponding to the number of dice of the dice, and (2) image patterns expressing morphological changes during one rotation of each die of the dice in 12 ways, (3) An image pattern in which the rotation direction is expressed in 12 ways, and as a result, “6 × 12 × 12 = 864 ways” image patterns are stored. An example of this is schematically shown in FIG. This Figure 12
Shows a part of the image pattern for the “first eye” image of the dice. Symbols P1, P2, ... Represent image patterns of form change during one rotation of the die, and these image patterns are provided in correspondence with the respective rotation directions A1 to A12.

The main CPU 17 executes this step S71.
Then, the image pattern of the last appearance (arbitrary appearance for the first time) is read from the image database 20 and transferred to the display memories 21 and 22 to be displayed on the CRT display 1. The display position coordinates on the CRT display 1 are preset corresponding to the respective operation units 2, and as an example, as shown in FIG. 6, the display position coordinates of the dice d corresponding to a certain operation unit 2 are (Xdo, Ydo). ), And the display position coordinates of the die D are (XDO, YDO).

In step S72, a 3-second timed timer is started, and the tracker 5 is operated by the shooter while the operation data is CP of the operation unit 2.
It is determined whether it is transmitted from U15, that is, whether the operation data is input (step S73). Here, the operation data transmission process by the CPU 15 will be described below with reference to the flowchart of FIG. 7.

The CPU 15 in the operation unit 2 is step T1
When it is determined that the trackball 5 has been operated, a 20 ms timed timer is started in step T2, and 20 ms
Each time the count values Xi and Yi of the X-counter 30 and the Y-counter 31 shown in FIG. 3 are read out, each counter is cleared. Then, in step T3, the count values "Xi" and "Yi" read at the present time are compared with the count values "X (i-1)" and "Y (i-1)" read immediately before. To do.

The CPU 15 is used for this comparison.
It is a register A and a register B provided inside (see FIG. 3). The previously read count value "X (i-1)" is registered in the register A, "Y (i-1)" is registered in the register B, and the count values "Xi", ""Xi> X (i-1)" and "Yi> Y (i-1)"
Is satisfied, the contents of registers A and B are changed to "X
Update with "i" and "Yi". This operation is called "Xi> X (i-
1) ”,“ Yi> Y (i-1) ”is not satisfied.

X-when the trackball 5 is operated
The relationship between the count value of the counter 30 and time is illustrated in FIG. 8, for example. That is, the above step T2
As a result of repeating the processing of T3 and T3, finally register A
The count value Xi registered in is the maximum count value Xm as shown in the figure. This also applies to the count value Yi of the Y-counter 31 finally registered in the register B, and the maximum count value Ym.
Becomes The maximum count values Xm and Ym of the X-counter 30 and the Y-counter 31 in this embodiment have an upper limit of "14".
It is set to "0" and the lower limit is specified to "20". That is, when the maximum count value is less than "20", it means that the trackball 5 has not been operated, and the maximum count values Xm and Ym take values in the range of "20 to 140".

At step T4, the initial velocity Vx of the trackball 5 in the X direction is calculated from Xm, and the initial velocity Vy of the trackball 5 in the Y direction is calculated from Ym. Since Xm and Ym are count values obtained at time intervals of 20 ms, the initial velocity Vx per 1 [ms] is given by "Xm / 20" and the initial velocity Vy is given by "Ym / 20".

At step T5, the horizontal direction component H is calculated from the phase difference between the output signals of the photodiodes D1 and D2 of the detector 9X.
(H = “+” or “−”) is determined, and the vertical direction component V (V = “+” or “−”) is determined from the phase difference between the output signals of the photodiodes D1 and D2 of the detection unit 9Y. As shown in FIG. 2, "+ and-" direction components are defined with respect to the horizontal direction (X) and the vertical direction (Y). This defines the direction in which the CRT display 1 is viewed from the trackball 5 as “+” in the vertical direction (Y). Therefore, each rotating shaft 8X, 8
When Y rotates clockwise with respect to the axis, it rotates in the "+" direction, and when it rotates counterclockwise, it rotates in the "-" direction. At this time, the slit 13 formed in the disk 10 attached to the rotary shafts 8X and 8Y first passes through the optical path of the light emitting diode 14, and the output signal of the photodiode D2 leads the output signal of D1 in phase. Becomes From this phase difference, each direction component of the trackball 5 is determined.

The calculated initial velocities Vx and Vy and the determined horizontal component H and vertical component V are transmitted to the main CPU 17. The above-mentioned operation data refers to these data.

Returning to the flowchart of FIG. 5, when the operation data is input in step S73, the process proceeds to step S76. On the other hand, when the operation data is not input within the time of 3 seconds, that is, the shooter moves the trackball 5
If the operation has not been performed, the process proceeds to step S75 to automatically create the operation data. This step S75
Then, in order to create operation data consisting of initial velocities Vx, Vy, horizontal direction component H, and vertical direction component V, first, of the 10-digit data generated by the random number generator 23, 8 digits excluding the digits at both ends are excluded. Select the data of.

When the selected 8-digit decimal number is divided by "240", the remainder takes a value of "0 to 239". "240
Here is the reason for dividing by. That is, as described above, the X-counter 30 and the Y-counter 30 which give the initial speeds Vx and Vy.
Since the maximum count values Xm, Ym of the counter 31 are set to take values of "20 to 140", the range of possible numerical values is "0 to 120". Horizontal component "+ or
"-" And the sign of the vertical component "+ or-" are added,
The range of possible numerical values is "-120 to +120",
This corresponds to the remainder value "0 to 239" of the random number.

Therefore, the remaining numerical value "0-239"
Can be used to express the initial velocities Vx and Vy in consideration of each direction component. Here, the remainder is "0 to 119" and the maximum count value of the (+) direction component is "20 to 140",
The maximum count value of the (-) direction component in "120 to 239" is "20 to 239
140 ”. After that, the created maximum count value is set to "1/20" in the same manner as described above, and the initial velocity V per 1 [ms] is set.
Data of x and Vy are generated.

The operation data of the trackball 5 input in step S73 or the operation data generated in step S75 has V-direction component (-) as shown in FIG.
It is assumed that Vy has a direction component of x, (+). In the next step S76, the speed V0 (= V1 = V2) of the two dies d and D and the rolling angle .theta.1,
Calculate θ 2 and.

First, the velocity V0 is calculated by the following equation (1).
In the equation (1), the symbol N is a coefficient that is set in advance.

[0033]

[Equation 1]

The angle θ3 between the speeds V0 and Vx (see FIG. 9)
(Reference) is calculated by the following equation (2).

[0035]

[Equation 2]

From the sign of the calculated angle θ3, the horizontal component H, and the vertical component V, the knitting angle θ of the velocity V0 with the horizontal component H as a reference is calculated as follows. When H = (+), V = (+), knitting angle θ = θ3 H = (+), when V = (−), knitting angle θ = 360−θ3 H = (−), V = (+ ), Knitting angle θ = 180−θ3 H = (−), V = (−), knitting angle θ = 180 + θ3 In this example, H = (−) and V = (+) θ
Calculated as = 180-θ3.

This knitting angle θ is the rolling angle θ of the dies d and D.
Although it may be used as 1 and θ2, it expresses the rolling state of the die when the die is actually swung, that is, "the rolling angle of the die that is a regular hexahedron is not constant even if the dice swing direction is the same". A minute angle θ4 (4 ° to 10 ° in this example) created by a random number is added to the knitting angle θ to obtain rolling angles θ1 and θ2. Here, the rolling angle θ1 is calculated by the knitting angle θ + θ4, and the rolling angle θ2 is calculated by the knitting angle θ−θ4. Further, the small angle θ4 is calculated as follows.

First, of the 10-digit data generated by the random number generator 23, 8-digit data excluding the digits at both ends is selected. Divide the selected 8-digit decimal number by "7" and obtain the remainder "0-6". Minute angle θ4 is (4 ° -10 °)
Since it is arbitrarily set in the range of, the value is made to correspond to the remainder value of "0 to 6". That is, if the value of the remainder is “0”, the minute angle θ4 is set to “4 °”, and if the value of the remainder is “1”, the minute angle θ4 is set to “5 °”. If it is "6", the minute angle θ4 is set to "10 °".

The minute angle θ4 obtained from the random numbers in this way
As described above, the rolling angles θ1 of the dies d and D are
Calculate θ 2. With this, the speed of the dice d and D V1 (= V
0), V2 (= V0) and rolling angles .theta.1, .theta.2 are obtained.

In step S77, the outcome of the dice d and D is determined using a random number. The result of dice d and D is "1.
Since a numerical value of "~ 6" can be taken, as in the previous calculation of the minute angle θ4, 8-digit data excluding the digits at both ends of the 10-digit data generated by the random number generator 23 is selected and selected. The decimal digit of the digit length is divided by "6" and the remainder value "0-5"
Get. Then, the remainder values of "0 to 5" are associated with the outcomes "1 to 6" of the dice d and D to determine the outcomes of the dice d and D.

In step S78, the spotlight illuminating the shooter and the illumination of the trackball 5 are turned off. In step S79, the interrupt programs 1 and 2 (interrupt programs 1 and 2) are set every 16 ms, and the speeds V1 and V2 of the dice d and D and the rolling angle θ1 are set.
The rolling mode of the dice d and D is displayed on the CRT display 1 based on θ 2. This interrupt program 1
Is related to the display processing of the dice d, and the interrupt program 2 is related to the display processing of the dice D. The interrupts of the interrupt programs 1 and 2 are the speeds V1 of the dice d and D,
It is executed until V2 becomes "0", that is, until the rolling of the dice d and D displayed on the CRT display 1 is stopped (steps S80 and S81). The processing procedure of the interrupt programs 1 and 2 will be described with reference to the flowchart of FIG.

The interrupt programs 1 and 2 are 16
It is a program that repeats the process of calculating the display coordinate values of the dice d and D on the CRT display 1 for each ms, selecting the image pattern of the dice d and D from the image database 20, and displaying the pattern. First, in step R1, "1" is subtracted from the speeds V1 and V2 of the dice d and D. In step R2, it is determined whether the dice d and D have collided with the wall,
If a collision occurs, the process proceeds to steps R3 and R4 to calculate the velocities V1 and V2 and the rolling angles θ1 and θ2 of the dies d and D thereafter. In step R5, it is determined whether the dice d and D collide with each other.
In step 7, the velocities V1 and V2 of the dies d and D thereafter and the rolling angles θ1 and θ2 are calculated.

Only 16 ms after the first interruption of the interrupt programs 1 and 2, that is, the dice d and D are rolled, the dice d and D are moved to the wall (CRT display 1
Since there is no situation in which the dies collide with each other or the dies d and D collide with each other, first, step R
2 and the display coordinate value calculation of the dice D and D in step R8 assuming that the determination is "NO" in step R5.

Since the velocities V1 and V2 of the dies d and D and the rolling angles θ1 and θ2 do not change due to the collision, the velocities V1 and V2 and the rolling angles θ1 of the dies d and D calculated in step S76 of the flowchart of FIG. , Θ2, the display coordinate value is calculated as follows. That is, FIG.
As shown in, the initial display coordinate value of the die d is (Xd0, Y
d0), the display coordinate value (Xd1, Yd1) of the die d when moving from this position in the direction of the rolling angle θ1 for 16 ms at speed V1 is calculated by the following equations (3) and (4). It

[0045]

(Equation 3)

[0046]

[Equation 4]

The display coordinate value of the die D (XD1, YD
Similarly, 1) is calculated by the following equations (5) and (6).

[0048]

(Equation 5)

[0049]

(Equation 6)

Next, in step R9, the image patterns of the dice d and D are selected from the image database 20, read out, and transferred to the display memories 21 and 22 to calculate the calculated CRT display 1 Display at the display coordinate value of. As described above, the image patterns of the dice d and D are (1) image patterns (6
, And (2) image patterns that represent morphological changes during one rotation of each eye of the die in 12 ways, and (3) image patterns that represent the rotation direction in 12 ways. From the image patterns, first, the pattern in the rotation direction closest to the rolling angles θ1 and θ2 is selected from 12 patterns, and then one image of the rolling mode of the dice d and D in the rotation direction is selected. It is displayed at the calculated display coordinate value. Taking the image pattern of FIG. 12 as an example, for example, the image pattern P1 in the rotation direction A1 closest to the rolling angle θ1 is read and displayed.

Returning to step R1, the above processing is repeated. As a result, an image expressing the rolling mode of the dice d and D is displayed while drawing the loci of L1 and L2 as shown in FIG. Next, the process (step R2) when the dice d and D collide with the end of the CRT display 1 will be described.

The calculated display coordinate values of the dice d and D "(Xdi, Ydi), (XDi, YDi), where i is the starting point 0.
~ End point n "becomes the coordinate value (X0, Xm, Y0, Ym) of the end portion of the CRT display 1 shown in FIG. 6 and it is determined whether the dice d, D collide with the end portion of the CRT display 1. Then, the process proceeds to step R3. Step R3
Then, the speeds V1 and V2 of the dies d and D are multiplied by "0.8" to decelerate them. The speed after deceleration is V11 and V12.

In the next reflection process of step R4, first,
The theoretical reflection angles of the dice D and D are calculated according to the law of reflection, and the angles (0 ° to 10 °) obtained by random numbers are added to this reflection angle to obtain the final reflection angles θ12 and θ22 (see FIG. 6). ) Is calculated. The angle (0 ° to 10 °) is added because the dice d and D are square and do not necessarily follow the law of reflection. The method of calculating the angle by the random number is the same as that described above, and the value of the random number output from the random number generator 23 is divided by "11" and the remainder value "0-10" is used. Note that θ14 and θ24 in FIG. 6 are similarly obtained.

Next, the processing when the dice d and D collide with each other (steps R5 to R7) is as follows.
Display coordinates of dice d, D “(Xdi, Ydi), (XDi,
YDi), where i is the start point 0 to the end point n "and the collision is judged, and the velocities V1 and V2 of the dies d and D are multiplied by" 0.8 "to obtain the velocities V11 and V12 after deceleration. Is calculated (step R6). Then, after obtaining the theoretical reflection angle, the angles using random numbers are added in the same manner as above to calculate the final collision reflection angles θ13 and θ23 (see FIG. 6). The velocities V12, V22 thus obtained and the respective reflection angles (θ12, θ13, θ14), (θ22, θ23, θ24) are substituted into the above formulas (3) to (6) to obtain the dice d, The display coordinate value of D is calculated (step R8).

When the speeds V1 and V2 of the dice d and D become "0" in the judgment of step S80 in the flowchart of FIG. 5 (when the rolling of the dice d and D theoretically stops), the interrupt is executed in step S81. The programs 1 and 2 are reset, and the results of the dice d and D are enlarged and displayed in step S82. This result is the result already calculated in step S77. This completes the effect display process of dice d and D (subroutine of step S7 of FIG. 4) and returns to the process of step S8 and subsequent steps of FIG. 4 already described.

[0056]

As is apparent from the above description, the dice display device for a computer game machine according to the present invention uses a trackball which has the same operability as the movement of the hand when "rolling the dice". Since the rolling mode of the dice is displayed based on the operation amount and the operation direction of the ball, "roll the dice" to the player of the game.
It is possible to give a feeling of that. Further, in the device according to the second aspect, since the minute angle obtained by using the random number is added to the rolling angle of the die calculated from the operating direction of the trackball, even if the operating direction of the trackball is the same. The rolling direction of the dice changes slightly each time. Therefore, like when you actually roll the dice, it is possible to display that "the dice roll direction can be changed even if the dice roll direction is the same", and the actual feeling of rolling the dice can be visually displayed. You can deepen it further.
