Description

The present disclosure relates to an information processing device, a program, and a game image generation method.

Conventionally, in sports games such as soccer and baseball, as one method of expressing the movement of individual spectators, which is a crowd, while reducing the processing load, textures simulating spectators are prepared, and a large number of polygons are arranged in the spectator seats. It is known how to map to For example, there is a conventionally known technique for realizing a highly realistic expression as if each individual member forming a set is individually controlled (see Patent Document 1, for example).

JP 2007-222413 A

For example, in the technique disclosed in Patent Document 1, a plurality of spectator polygons are arranged on the stand to form spectators, which are a large number of crowds existing in the stand. The spectator polygon is generated by mapping a plurality of spectator textures onto one rectangular plate polygon. The spectator texture is a texture obtained by rendering a spectator model, which is an object (model) imitating the spectator.

In recent years, musou games have become known in which a player character knocks down a large number of enemy characters. In Musou games, a large number of enemy characters appear at once, so by mapping multiple enemy textures onto a single plate polygon to generate an enemy polygon model, the number of polygons placed on the game screen can be reduced. Processing load can be reduced.

However, when using an enemy polygon model in which multiple enemy textures are mapped onto a single plate polygon, for example, an enemy character model that is blown away by an attack by the player character or flees will escape or be blown away in units of plate polygons. There was a risk that it would be done or done, and the sense of presence would be lost. In addition, patent document 1 does not solve such a subject.

An object of the present disclosure is to reduce the processing load of a game that generates an image in which a plurality of objects move separately while maintaining a sense of realism.

[Multiple enemy polygons and single enemy polygons]
FIG. 4 is a diagram showing the configuration of a multiple enemy polygon model and a single enemy polygon model. FIG. 4A shows the structure of the multi-enemy polygon model 1004. FIG. FIG. 4B shows the configuration of the single enemy polygon model 1014 .

A multi-enemy polygon model 1004 is generated by mapping textures 1000 of multiple (three in FIG. 4) enemy characters onto a plate polygon 1002 called a billboard. Note that the texture 1000 in FIG. 4 shows an example of the texture obtained by rendering the same enemy character, but the texture may be obtained by rendering different enemy characters. Also, the single enemy polygon model 1014 is generated by mapping the texture 1010 of the single enemy character onto the normal polygon model 1012 .

As shown in FIG. 4, the multi-enemy polygon model 1004 can draw a plurality of enemy characters with a single plate polygon 1002, so the number of polygons to be drawn can be reduced and the processing load for generating game images can be reduced. can. However, since the multi-enemy polygon model 1004 draws a plurality of enemy characters with a single plate polygon 1002, if the scene of enemy characters being blown away is displayed as it is, the multiple enemy characters will be blown away in exactly the same way. As a result, there is a risk that the sense of reality will be lost.

On the other hand, in the single enemy polygon model 1014, since one enemy character is drawn with one polygon model 1012, the number of polygons to be drawn cannot be reduced more than in the multiple enemy polygon model 1004. It is possible to display the characters separately (separately) and blow them away, so that the presence can be maintained.

Therefore, in the present embodiment, in order to reduce the processing load of the game that generates an image in which a plurality of enemy characters are blown away while maintaining a sense of realism, among the multiple enemy polygon models 1004 arranged in the game image, Rendering of the multiple enemy polygon model 1004 that has been blown away is changed to rendering of a plurality of single enemy polygon models 1014 .

More specifically, in the example of FIG. 4, when the three enemy characters displayed as multiple enemy polygon models 1004 are blown away, the three enemy characters are displayed as three single enemy polygon models 1014. , it is possible to display three enemy characters separately blown away.

[process]
An example of processing in which the game system according to the present embodiment receives a game operation from a user, generates a game image according to the operation, and displays (outputs) the image on the output device 108 will be described below. FIG. 5 is a flowchart of an example of processing of the game system according to this embodiment.

In step S10, the information processing apparatus 10 receives an operation from the user to start playing the game. The game control unit 230 of the information processing device 10 starts executing game processing according to an operation received from the user.

In step S12, the game control unit 230 selects models of objects such as player characters and enemy characters required for the generated game image, and requests the texture generation unit 240 to generate textures for the respective models. The texture generator 240 generates the texture of the requested object.

The polygon drawing unit 242 maps the texture of the object of the enemy character onto the plate polygon 1002 or the normal polygon model 1012 shown in FIG. The image generator 246 generates a game image in which the multiple enemy polygon model 1004 and the single enemy polygon model 1014 are arranged as objects in the object space. The output control unit 204 displays the game image generated by the image generation unit 246 on the output device 108 .

FIG. 6 is an image diagram of an example of a game image in which multiple enemy polygon models and single enemy polygon models are arranged as objects. FIG. 6 shows an example of a game image in which multiple enemy polygon models 2000 to 2014 and a single enemy polygon model 1014 are arranged as objects. In FIG. 6, the multiple enemy polygon models 2000 to 2014 are surrounded by dotted lines for easy recognition. Dotted lines surrounding multiple enemy polygon models 2000 to 2014 are not displayed in the actual game image. Also, FIG. 6 shows an image example of a game in which a polygon model of a player character is not arranged as an object.

In step S14, the game control section 230 determines whether an attack has been made on the enemy character. If the enemy character has not been attacked, the game control section 230 skips the processes of steps S16 to S20 and performs the process of step S22.

If the enemy character has been attacked, the attack determination section 248 of the game control section 230 performs the process of step S16. In step S16, the attack determination unit 248 determines whether or not the multi-enemy polygon model 1004 displayed in the game image has been attacked and blown away.

If the multiple enemy polygon model 1004 is not in a state of being blown away, the game control unit 230 determines that the single enemy polygon model 1014 is in a state of being blown away, skips the processing of step S18, and skips step S20. process.

If the multi-enemy polygon model 1004 is in a state of being blown away, the polygon changing section 244 performs the process of step S18. In step S18, the polygon changing unit 244 changes the drawing of the multiple enemy polygon model 1004 that has been blown away to the drawing of the single enemy polygon model, and then performs the processing of step S20.

FIG. 7 is an image diagram of an example of a game image in which a multiple enemy polygon model that has been blown away is changed to a single enemy polygon model. FIG. 7 shows an example in which the multi-enemy polygon model 2002 arranged in the game image of FIG. 6 is blown away. Drawing has been changed.

In the process of step S18, in the case of the screen image of FIG. 7, one multiple enemy polygon model 2002 that has been blown away is separated into three single enemy polygon models 2018-2022.

In step S20, the image generation unit 246 generates a game image in which the single enemy polygon model 1014 that is to be blown away is separately blown away, including the single enemy polygon model 1014 changed from the multiple enemy polygon model 1004. The output control unit 204 displays the game image generated by the image generation unit 246 on the output device 108 .

FIG. 8 is an image diagram of an example of a game image showing how a single enemy polygon changed from a multiple enemy polygon model is blown away. FIG. 8 shows a different action in which three single enemy polygon models 2018 to 2022 changed from the multiple enemy polygon model 2002 that has been blown away are blown away in different directions.

In step S22, the game control section 230 determines whether or not the game is over. If the game is not over, the game control unit 230 returns to step S12 and continues the game processing shown after step S12. If the game is over, the game control unit 230 ends the processing of the flowchart of FIG.

In this way, in this embodiment, an enemy character before being blown away is rendered as a multi-enemy polygon model 1004 to reduce the processing load, while an enemy character being blown away by an attack or the like is rendered as a single enemy polygon model. By redrawing at 1014, it is possible to maintain the presence of the scene in which the enemy character is blown away.

In this embodiment, an example of a game image has been described. It is also possible to apply it to a screen that changes to a state in which NPCs are flying around and moving separately.

According to this embodiment, in the information processing apparatus 10 that generates an image of the object space viewed from a predetermined viewpoint and causes the user to execute a game, a plurality of objects are blown away in different directions, or a plurality of objects are separated from each other. It is possible to reduce the processing load of the game that generates images such as running away in the direction of , while maintaining a sense of realism.

The information processing apparatus of the disclosed embodiment should be considered as an example and not as a limitation. The embodiments described above can be modified and improved in various ways without departing from the scope and spirit of the appended claims. In addition, the items described in the above-described multiple embodiments can be configured in other configurations within a consistent range, and can be combined within a consistent range.
