[0020]
【Example】
FIG. 1 is a block diagram showing a configuration example of a game apparatus to which the screen switching method of the present invention is applied. 2 to 4 are examples of an operation flow of the screen switching method of the present invention. Further, FIGS. 5 to 8 are operation explanatory diagrams corresponding to the operation flows of FIGS.
[0021]
Embodiments of the present invention will be described below with reference to these drawings.
In FIG. 1, reference numeral 1 denotes a CPU, which controls execution of a game program stored in a ROM 2 composed of a compact disk or a semiconductor memory.
[0022]
The ROM 2 further stores image data corresponding to the game. The image data is composed of background scroll image data and sprite image data. Here, the background scrolling image data is data constituting the background image, read from the ROM 2, developed and stored in the video RAM 3.
[0023]
The image data for background scrolling developed in the video RAM 3 is composed of data corresponding to a larger area including the display surface of the monitor.
[0024]
On the other hand, the sprite image data is data for displaying a specific shape on a background image corresponding to a specific code. For example, in the case of a hostile game, the main character whose display position, movement, etc. are controlled by the player's input operation, or the enemy's character, whose enemy is the host character, whose display position, movement, etc. are controlled by the program. Characters, etc.
[0025]
Further, the image data for sprite is different from the image data for background scrolling in that the size of the original picture for enlargement / reduction can be freely determined to some extent.
The sprite image data is read from the ROM 2 and stored in the video RAM 5.
[0026]
The image data for background scrolling developed and stored in the video RAM 3 is sequentially transferred and stored in the field memory 8 as scroll data for an area corresponding to one screen by the video display processor 4.
[0027]
At the same time, the sprite image data stored in the video RAM 5 is transferred to the frame buffer 7 by the video display processor 6.
[0028]
Further, the sprite image data transferred to the frame buffer 7 becomes video data and is sent to the field memory 8 where it is combined with the image data for background scrolling to become video data for one screen. Video data for one screen of the field memory 8 is sequentially sent to the monitor 9 to display one screen.
[0029]
2 to 4 are operation flows of the screen switching method according to the present invention, which is executed in the video game apparatus having the above-described configuration.
[0030]
First, in the flow of FIG. 2, when one segmented scene of the game scene ends (step S1), the video display processor 4 causes the background scroll image area stored in the video RAM 3 to scroll within the range at the end of the segmented scene. Is determined (step S2).
[0031]
Next, the background scroll image data corresponding to the determined scroll range is transferred to an empty area of the video RAM 5 for sprites (step S3).
[0032]
Further, the video display processor 6 overwrites the empty area of the video RAM 5 with the contents of the sprite frame buffer 7 at the end of the delimiter scene (step S4).
[0033]
As a result, the screen at the end of the break scene is rewritten as sprite image data (step S5).
[0034]
The above operation will be further described with reference to FIG. That is, FIG. 5A is an example of a screen displayed on the monitor 9 at the end of the break scene.
[0035]
FIG. 5B is a background scroll image displayed by the background scroll image data in the scroll range on the screen at the end of the above-described segment scene. FIG. 5 (3) shows a scroll range (area surrounded by a thick line) of the image of FIG. 5 (2) in the background scroll data stored in the video RAM 3. The area coordinates are determined by the video display processor 4, and the corresponding data is transferred to the empty area of the video RAM 5.
[0036]
FIG. 5 (4) shows a sprite screen corresponding to the contents of the sprite frame buffer 7 at the end of the break scene. The sprite image data corresponding to the sprite screen is overwritten on the background scroll data transferred to the empty area of the video RAM 5 and rewritten as sprite image data.
[0037]
Further, in FIG. 3, the polyhedral three-dimensional data stored in the ROM 3 is called and stored in the video RAM 5 (step S6). This polyhedron is, for example, a hexahedron in the example shown in FIG.
[0038]
Here, this polyhedron image is displayed on the monitor 9 so as to rotate in accordance with the game program stored in the ROM 3. Such display is performed by calling and storing polyhedron data in the video RAM 5 and processing it as image data for the sprite by the video display processor 6.
[0039]
That is, the polyhedron data stored in the video RAM 5 is updated by sequentially updating the vertex coordinates and deforming the polyhedron, and the update data of the deformation process is transmitted to the monitor 9 through the sprite frame buffer 7 and the field memory 8. Is displayed.
[0040]
Further, in the process of sending the update data to the monitor 9, the video display processor 6 corresponds to the vertex of one side of the polyhedron corresponding to the data of the final screen of the segmented scene stored as a sprite in the empty area of the video RAM 5, and the four vertices of the final screen correspond. (Step S7).
[0041]
This situation is shown in FIGS. That is, A, B, C, and D in FIG. 7B are the four vertices of the final screen, and a, b, c, and d are the vertices of one surface of the polyhedron. Therefore, the video display processor 6 fixes each of the four vertices A, B, C, and D of the final screen data handled as the image data for the sprite corresponding to the vertices a, b, c, and d on one side of the polyhedron. .
[0042]
Thereby, as shown in 60 of FIG. 6 or FIG. 7 (1), the sprite and the background scroll image are overwritten to form the sprite image, and the final screen of the delimiter scene is fitted to one surface of the polyhedron.
[0043]
Next, the start screen of the next segment scene is fixed to the other surface of the polyhedron (step S8). This method is also performed in the same procedure as that for fixing the final screen, and the data for the start screen of the next break scene is also read from the ROM 2 into the video RAM 5.
[0044]
Reference numeral 61 in FIG. 6 denotes a start screen for the next segment scene. In the example shown in FIG. 6, the screen is inserted into a surface adjacent to the final screen of the previous segment scene.
[0045]
When the final screen of the previous segment scene and the start screen of the next segment scene are fixed, the polyhedron is rotated (step S9). The rotation of the polyhedron is performed by control of the video display processor 6.
[0046]
That is, the video display processor 6 deforms the polyhedron sprites so that the vertices of the polyhedron are sequentially moved and displayed as the polyhedron rotates according to the contents of a predetermined program. As a result, the display is as shown in FIG.
[0047]
In FIG. 7A, reference numeral 70 denotes the display surface of the monitor 9, and reference numerals 60 and 61 denote the final screen of the previous segment scene and the start screen of the next segment scene fixed to the polyhedron surface described in FIG. is there. As described above, the polyhedron is displayed so as to rotate as indicated by the arrows in the figure by sequentially deforming the polyhedron sprite.
[0048]
Next, moving to the operation flow of FIG. 4, the polyhedron is rotated and moved so that the screen at the start of the next segmented scene becomes a normal screen (step S10). The state at this time is as shown in FIG.
[0049]
Then, under the control of the CPU 1, a game start routine for the next break scene is read from the ROM 2 (step S11). After that, the display is switched to the normal display according to the read game program (step S12), and the game of the next break scene is continued [see step S13: FIG. 8 (2)].
[0050]
Furthermore, for the above embodiment, it is also possible to display the narration related to the development of the separated scene by voice or characters until the polyhedron rotates to display the start screen of the next separated scene. Thereby, it is possible to maintain the user's interest even during the display switching period.
[0051]
【The invention's effect】
As described above according to the embodiment, the present invention converts the background scroll data into image data for sprites and inserts it into the polygon of the rotating polyhedron. Thereby, according to the rotation of the polyhedron, it is possible to shift from the final screen of the previous segment scene to the start screen of the next segment scene.
[0052]
Therefore, according to the present invention, continuous screen switching is possible, and it is possible to provide a video game in which the player is interested.
