However, signal output from the display control device 150 to the game control device 100 is prohibited.
.
[0050]
FIG. 3 is a state transition diagram of the gaming machine according to the embodiment of the present invention. The outline of the game will be described according to this state transition diagram. In the following description, the variable display area of the variable display device 8 will be described as the left, right, and middle variable display areas.
[0051]
First, at the beginning of the game (or before the game is started), the customer is in a waiting state, and a display control command signal for instructing the display of the customer waiting screen is transmitted from the game control device 100 to the display control device 150 and changed. On the display screen of the display device 8, a customer waiting screen that is a moving image or a still image is displayed.
[0052]
Then, when the game ball launched into the game area wins the start opening 16, a predetermined random number is extracted by the game control device 100, a big win lottery of the variable display game is performed, and the win is used as a special symbol start memory. Remembered. Then, a display control command signal for instructing a variable display is transmitted from the game control device 100 to the display control device 150, and a variable display of a plurality of symbols is started in the left, right, and middle variable display areas of the screen of the variable display device 8. Is done.
[0053]
When a predetermined time has elapsed after the start of the fluctuation display, the fluctuation display temporarily stops in the order of left, right, and middle. In this process, the reach state (for example, the left symbol and the right symbol generate a combination of jackpots). A predetermined reach game is performed. In this reach game, for example, the inside symbols are displayed in a variably displayed state at a very low speed, variably displayed at a high speed, or the variably displayed state is reversed. In addition, background display and character display in accordance with the reach game are performed.
[0054]
The temporary stop state is a state in which the final stop symbol is not determined as a substantially stop state in which the player can recognize the symbol. Specifically, in addition to slightly changing the symbol at the stop position, modes such as rotating the symbol, scaling the symbol, changing the symbol color, changing the symbol shape, etc. There is.
[0055]
If the winning symbol lottery result is a big hit, the left, right, and middle symbols are finally stopped in a predetermined big hit combination, and a big hit is generated.
[0056]
When this big hit game is generated, a special game is performed in which the special variable winning device 10 is opened for a predetermined period. This special game is executed with a predetermined number (for example, 10) of game balls to be awarded to the special variable winning device 10 or the passage of a predetermined time (for example, 30 seconds) as one unit (one round). Is repeated on the condition of winning a winning prize (detecting a winning ball by the continuation sensor 54) in a predetermined round (for example, 16 rounds). When a big hit game is generated, a signal for instructing the display control device 150 to display a big hit game, such as a big hit fanfare display, a round number display, a big hit effect display, etc. is transmitted to the display control device 150, and the display of the variable display device A big hit game is displayed on the screen.
[0057]
If this jackpot is a specific jackpot, a specific gaming state will occur after the jackpot game, and the probability of the next jackpot occurrence will be high (probability change state), or the fluctuation display time of the usual variable display game will be shortened ( Etc.) and the player becomes more advantageous.
[0058]
Then, if there is a special symbol start memory when the variable display game is finished (when lost) or when the big hit game is finished, a new variable display game is repeated based on the special symbol start memory. Further, when the variable display game is finished (when it is lost), if there is no special symbol start memory, it is returned to the customer waiting state.
[0059]
A random number related to the normal symbol is extracted based on the passing of the game ball through the normal symbol starting gate or the normal symbol starting memory, and if the random number is hit, the normal symbol display unit 7 is hit and displayed. The normal variation winning device 9 provided in the foreground is expanded over a predetermined time, and winning at the start port 16 is facilitated.
[0060]
FIG. 4 is a flowchart of the three-dimensional drawing process executed in the display control device 150. This three-dimensional drawing process is performed mainly by the CPU 151 and the VDP 152.
[0061]
When a display control command signal is received from the game control device 100 in a command reception process to be described later, a scene and 3D object for 3D display are determined (S1).
[0062]
Then, a world transform process is performed in which the selected 3D object is placed in a preset virtual three-dimensional space (world space) (S2). This world transform process converts a model space set for each 3D object into a world space, and includes conversion of rotation, scaling, position, size, and the like of the 3D object.
[0063]
Next, a view transform that converts the world space obtained in step S2 from the position and direction of the viewpoint (view) in the world space corresponding to the scene determined in step S1 to a camera space having the viewpoint as the origin. Processing is performed (S3).
[0064]
Then, a projection transform process is performed to convert the camera space obtained by the view transform process in step S3 into a three-dimensional space corresponding to the field of view (viewing angle) of the camera (S4). As a result, the 3D object in the field of view is extracted, the 3D object close to the camera is greatly enlarged, and the 3D object far from the camera is reduced.
[0065]
Then, a clipping process for converting the 3D object (polygon data) in the three-dimensional space corresponding to the field of view of the camera into a cubic space corresponding to the screen coordinates (display area) of the variable display device 8 is performed (S5).
[0066]
The processing in steps S2 to S5 is a so-called geometry calculation. Here, an example is shown in which the CPU 151 performs a geometry calculation process and the VDP 152 performs a rasterization process after the geometry calculation.
[0067]
Next, lighting processing is performed on each polygon data clipped in step S5 based on the light source set in the virtual three-dimensional space (S6). As an example of this lighting, a reflection or the like corresponding to a shadow or a polygon material is calculated. At this time, for the polygon data (design objects written in different frame buffers in S10) used for drawing other symbol objects calculated in the process up to S5, all the symbol objects using the polygon data are used. A lighting process using parallel rays is performed on both the original symbol object and the symbol object used by copying polygon data. In other words, the display control apparatus performs lighting processing based on a light source that emits parallel rays to the drawing data calculated by one polygon calculation, and draws the plurality of symbol objects having the same polygon.
[0068]
Then, texture mapping for pasting a predetermined texture on the surface of each polygon is performed to determine the appearance of the 3D object (S7). In this texture mapping, not only simple texture pasting, but also processing such as light mapping, environment mapping, and bump mapping is performed on a 3D object after performing predetermined processing.
[0069]
Next, depth (depth) information is determined for pixels on each polygon for which texture mapping in step S7 has been completed (S8). That is, the depth information is checked for each pixel of all polygons, and when the pixel is closer to the camera than the depth stored in the depth buffer, the pixel is displayed and the depth information in the depth buffer is updated. By performing this process for all polygons, completely rendered 2D drawing data is completed.
[0070]
Then, the 2D drawing data is written into a frame buffer provided in the DRAM 154 (S9). Through the above process, a 3D image for one frame is generated.
[0071]
Then, the necessary portion of the drawing data is written into a different frame buffer provided in the DRAM 154 (S10). Then, the frame buffer in which the drawing data is written is synthesized and displayed (overlay display) (S11). At this time, the frame buffer is shifted and superimposed according to the positional relationship of the displayed symbol objects.
[0072]
In step S10, the necessary portion of the drawing data is drawn shifted from the drawing position in the main frame buffer, and the frame buffers are overlapped at the same position without displaying different frame buffers. You may comprise so that it may draw.
[0073]
Further, in the above-described lighting processing in step S6, the lighting processing based on parallel rays is performed. However, the design object and other objects (character, background, etc.) are illuminated with different light sources, the illumination on the design object and the like. Lighting processing may be performed so that the illumination of the object is different. That is, a plurality of light sources are set in the three-dimensional space, and the light sources for the objects set in the three-dimensional space are set independently. For example, a character, background, etc. are provided with a light source below the virtual three-dimensional space and illuminated from below. The symbol object is provided with a light source in the horizontal direction and illuminated from the horizontal direction.
[0074]
With this configuration, the player can be informed that the space where the symbol object is displayed and the space where the display effect is displayed by other objects are independent, and the drawing data of the symbol object can be shared. The uncomfortable feeling due to can be reduced.
[0075]
Further, in the above-described lighting processing in step S6, lighting processing based on the same parallel rays is performed for a predetermined symbol object to reduce the amount of calculation regarding a plurality of symbol objects having the same polygon. It is also possible to draw a symbol object by changing the way the light strikes (lighting). That is, when performing lighting processing based on a point light source, or when changing the light source for each pattern object, the light intensity and the illumination direction change depending on the position of the pattern object, so the polygon obtained by the processing up to step S5 Data can be used in common, and the processing after step S6 can be configured to be calculated separately for each symbol object.
[0076]
If comprised in this way, the calculation amount regarding three-dimensional drawing can be reduced, displaying a realistic (real) display about a symbol object.
[0077]
As described above, it is possible to display a 3D image in accordance with the command of the game control device 100 by repeatedly executing the above steps S1 to S11.
[0078]
FIG. 5 is another flowchart of the three-dimensional drawing process executed in the display control device 150.
[0079]
In the three-dimensional drawing process shown in FIG. 5, unlike the three-dimensional drawing process described in FIG. 4, a process using only one frame buffer for writing drawing data will be described. Since the process until the end of the rendering process of the three-dimensional drawing process illustrated in FIG. 5 (S21 to S28) is the same as the process of steps S1 to S8 described with reference to FIG.
[0080]
When the rendering process ends in step S28, the display positions of a plurality of symbol objects displayed on one screen are calculated. The calculation of the display position includes a method of calculating a relative position from a symbol object displayed at a known position and a method of calculating absolute positions (position coordinates on the frame buffer) of a plurality of symbol objects. . Then, an offset amount is set from the calculated display position (S29).
[0081]
Then, using the drawing data of the portion that needs to be drawn a plurality of times and the offset value set in step S29, the data (drawing data) of the symbol object of the same graphic is generated (S30).
[0082]
Then, the drawing data is written into a different frame buffer provided in the DRAM 154 (S31). In this writing to the frame buffer, both the drawing data generated by the rendering processing up to step S28 and the drawing data of the symbol object generated by the processing such as offset (S29, S30) are written.
[0083]
The display control in FIGS. 4 and 5 is appropriately selected according to the architecture of the CPU 151 and the VDP 152. For example, an example in which the CPU 151 performs steps S2 to S5 in FIG. The processing after step S2 can also be executed, and the processing after step S2 can also be executed by the hardware of the VDP 152.
[0084]
FIG. 6 is a flowchart of command reception processing executed in the display control device 150.
[0085]
From the game control device 100 to the display control device 150, a communication interrupt signal is transmitted as a pulse signal according to the operation cycle (for example, 2 milliseconds) of the game control device 100, and the game control device is synchronized with the communication interrupt signal. A display control command signal (display control command) is sent from 100 to the display control device 150. When the display control device 150 detects a communication interrupt signal, it causes the CPU to generate an interrupt and execute a command reception process.
[0086]
In the command reception process, the display control device 150 reads the display control command signal from the game control device 100 in accordance with the communication interrupt signal (S41). Then, the contents to be displayed (such as the type of reach) are analyzed from the received display control command signal, and a variation pattern is set (S42). Then, the process returns to the display control main routine.
[0087]
When the display control command signal is not related to the variation pattern but is a display control command signal that changes the display mode (for example, lighting) of the symbol object as the variation display mode, data regarding the display mode is set. It can also be configured as follows.

FIG. 7 is a diagram showing a display example of the symbol object on the variation display device 8 in the variation display game. The state from the temporary stop state (a) with the big hit symbol to the symbol determination (d) after the full rotation variation. Indicates.
[0089]
In the temporary stop state shown in FIG. 7A, all the symbol objects are aligned with the same identification information displayed, and are repeatedly moved up and down, or the symbols are enlarged or reduced. This symbol object is the same figure and is composed of the same polygon. Accordingly, a single symbol object (for example, a middle symbol) is subjected to polygon calculation by rendering processing (steps S2 to S8 or S12 to S18), and the symbol object is displayed. Then, other symbol objects (for example, the left symbol and the right symbol) are displayed using the polygon calculation result regarding the symbol (for example, the middle symbol) on which the polygon calculation is performed.
[0090]
FIG. 7B shows the total rotation fluctuation state. In the all-rotation variation state, the variation display is performed in a state where all the symbol objects are aligned. Since this symbol object is composed of the same polygon, the polygon object is calculated by rendering processing (steps S2 to S8 or S12 to S18) for one symbol object (for example, middle symbol), and the symbol object is displayed. To do. Then, other symbol objects (for example, the left symbol and the right symbol) are displayed using the polygon calculation result regarding the symbol (for example, the middle symbol) on which the polygon calculation is performed. That is, a plurality of symbol objects are drawn based on the drawing data calculated by one polygon calculation with respect to a plurality of symbol objects displaying the same identification information during the variable display.
[0091]
Then, after the temporary stop state (FIG. 7 (c)), the variable display of the symbol object is stopped and the identification information is determined (FIG. 7 (d)).
[0092]
FIG. 8 is a diagram showing a display example of the symbol object on the variation display device 8 in the variation display game. From the temporary stop state (a) in the jackpot symbol, only the middle symbol is changed to the symbol determination (d). Indicates the state.
[0093]
In the temporary stop state shown in FIG. 8A, as in FIG. 7A, the polygon calculation is performed on one symbol object to display the symbol object, and the other symbol objects are related to the one symbol object. Display using polygon calculation results.
[0094]
FIG. 8B shows a state in which only the middle symbol is displayed in a variable manner. At this time, the left and right symbol objects are temporarily stopped.
[0095]
The left and right symbol objects display the same identification information, are the same figure, and are composed of the same polygon. Therefore, a polygon calculation is performed on any of the symbol objects (for example, the left symbol) by rendering processing (steps S2 to S8 or S12 to S18), and the symbol object is displayed. The other symbol object (for example, the right symbol) is displayed using the polygon calculation result relating to the symbol (for example, the left symbol) for which the polygon calculation has been performed.
[0096]
Then, after the temporary stop state (FIG. 8C), the change display of the symbol object is stopped and the identification information is determined (FIG. 8D).
[0097]
FIG. 9 is a diagram showing an example of the symbol object displayed on the variation display device 8 in the variation display game, and shows a case where more complicated polygon calculation is required.
[0098]
In the state shown in FIG. 9, the middle symbol is displayed on a barrel that rolls on the center of the screen, and the identification information is changed by the rotation of the barrel. In addition, the left symbol and the right symbol are produced in a temporarily stopped state at the upper corner of the display area. That is, in the state shown in FIG. 9, the temporary stop state is displayed on the left symbol and the right symbol with the barrel extending and contracting up and down. FIG. 9A shows a state where the barrels as the left symbol and the right symbol are extended, and FIG. 9B shows a state where the barrels as the left symbol and the right symbol are contracted.
[0099]
At this time, for the left symbol, the polygon calculation is performed by the rendering process (steps S2 to S8 or S12 to S18), and the barrel which is the temporarily stopped left symbol is displayed. The right symbol that is temporarily stopped, which is the other symbol, is displayed using the polygon calculation result relating to the left symbol that has undergone the polygon calculation.
