Description

Technical Field

[0001] The present application relates to the technical field of game special effects, and in particular to a method and device for realizing shuttle special effects, a storage medium, and a computer device. Background Art

[0002] In order to enrich their daily lives, more and more people choose to spend their time playing games, especially some mobile games and online games. In order to enrich the game content and enhance the game visual effects, a large number of game special effects are usually set up and added to the game scenes.

[0003] In the game world, it is common for game characters to enter from one scene to another. In order to enrich the visual effects when the game characters enter the scene, some games currently set a transparent barrier at the dividing position of the two scenes. The game characters can shuttle from the barrier to another scene. When the game characters shuttle, in order to reflect the interaction between the game characters and the barrier, some special effects are displayed on the barrier to distinguish it from the performance when the barrier is not shuttled. At present, the more common practice is to use particle effects to show the interaction. When the game characters pass through the barrier, the particle effects are played at the shuttle position. However, the particle effects displayed in this way are relatively monotonous and the effect is not ideal. Summary of the invention

[0081] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0082] In this embodiment, a method for realizing the shuttle special effect is provided, such as Figure 1 As shown, the method includes:

[0083] Step 101, when it is detected that the virtual character enters a preset special effect rendering range corresponding to a target shuttling barrier, determining a shuttling contact area of ​​the virtual character with respect to the target shuttling barrier, wherein the shuttling contact area matches the current shape and action of the virtual character.

[0084] Step 102, displaying the shuttling special effect of the virtual character on the target shuttling barrier according to the shuttling contact area, wherein the shuttling special effect is manifested as a special effect related to the outline of the virtual character left behind when the virtual character shuttles the target shuttling barrier.

[0085] In an embodiment of the present application, a target shuttle barrier refers to a virtual barrier in the game world that a virtual character can pass through and that leaves a shuttle special effect when passing through. For example, the target shuttle barrier can be a barrier, a virtual door, etc. that needs to be passed through to enter the immortal palace (or a sect, academy, etc.) from the game world. In the process of the virtual character moving in the game world, when it is detected that the virtual character has entered the preset special effect rendering range corresponding to the target shuttle barrier, when the virtual character approaches the target shuttle barrier, the area where the virtual character visually contacts the target shuttle barrier can be determined based on the current shape and action of the virtual character, that is, the shuttle contact area. Further, based on the shuttling contact area of ​​the virtual character to the target shuttle barrier, the shuttle special effect formed on the target shuttle barrier due to the virtual character shuttling through the target shuttle barrier is displayed, visually forming a special effect related to the virtual character's own outline when passing through the target shuttle barrier. The shuttle special effect can be directly expressed as leaving the outline of the shuttle contact area between the virtual character and the target shuttle barrier on the target shuttle barrier. In order to show a more vivid special effect, the shuttle special effect can also be processed by edge blurring, distortion, etc. based on the outline of the shuttle contact area to avoid the more blunt direct outline effect. For example, when the virtual character wears game costumes and passes through the target shuttle barrier, it leaves a special effect related to the outline that matches the shape of the game costumes it wears and the action of the virtual character when passing through the barrier. Compared with the single shuttle special effect currently generated by the particle system, the shuttle special effect generated by the embodiment of the present application is related to the shuttle contact area of ​​the target shuttle barrier when the virtual character passes through the target shuttle barrier. Different virtual characters can produce different shuttle special effects that match their respective shapes and actions. The same virtual character can also produce different shuttle special effects with different shapes or actions. The shuttle special effect is more vivid, more real, and richer.

[0086] In an embodiment of the present application, optionally, determining the shuttling contact area of ​​the virtual character with respect to the target shuttling barrier in step 101 includes: determining the shuttling contact area of ​​the virtual character with respect to the target shuttling barrier frame by frame until it is detected that the virtual character leaves the preset special effect rendering range; accordingly, step 102 includes: displaying the shuttling special effects of the virtual character with respect to the target shuttling barrier on the target shuttling barrier frame by frame according to the shuttling contact area of ​​each frame, so as to express the contour-related special effects with dynamically changing effects left on the target shuttling barrier when the virtual character shuttles.

[0087] In this embodiment, it generally takes a process for the virtual character to pass through the target shuttle barrier. In order to display the shuttle special effects more dynamically and vividly, the shuttling contact area of ​​the virtual character on the target shuttle barrier can also be obtained frame by frame, and the shuttling special effects can be displayed on the target shuttle barrier frame by frame according to the shuttling contact area, thereby showing the effect of the virtual character leaving a dynamically changing outline-related special effects on the target shuttle barrier during the process of passing through the target shuttle barrier. The shuttle special effects formed on the target shuttle barrier in the game show a visual effect that changes with the change of the contact area with the target shuttle barrier during the movement of the virtual character, further making the shuttle special effects more vivid and realistic.

[0088] By applying the technical solution of this embodiment, when it is detected that the virtual character enters the preset special effect rendering range of the target shuttle barrier, the shuttle contact area of ​​the virtual character to the target shuttle barrier is determined according to the current shape and action of the virtual character, so that the shuttle special effect is displayed on the target shuttle barrier according to the shuttle contact area, showing that the virtual character leaves a special effect related to the outline of the virtual character on the barrier when shuttling the target shuttle barrier. The shuttle special effect shown in the embodiment of the present application is generated based on the shuttle contact area of ​​the virtual character with the target shuttle barrier when shuttling the target shuttle barrier, and can visually show that the virtual character leaves a contour special effect matching the current shape and action of the virtual character when passing through the target shuttle barrier. Based on this method, different virtual characters can produce different shuttle special effects matching their respective shapes and actions, and the same virtual character can also produce different shuttle special effects when the shape or action is different. The shuttle special effect is more vivid, more real, and richer, so that players can get a more interesting experience when controlling the virtual character to pass through the barrier in the game, increase the fun of the player when experiencing the game, and provide technical support for game developers for game development.

[0089] Further, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for realizing the shuttle special effect is provided, such as Figure 2 As shown, the method includes:

[0090] Step 201, when it is detected that the virtual character enters a preset special effect rendering range corresponding to a target shuttling barrier, the shuttling contact area of ​​the virtual character with respect to the target shuttling barrier is determined frame by frame until it is detected that the virtual character leaves the preset special effect rendering range, wherein the shuttling contact area matches the current shape and action of the virtual character.

[0091] In an embodiment of the present application, starting from detecting that the virtual character enters the preset special effects rendering range of the target shuttling barrier, the shuttling contact area of ​​the virtual character with respect to the target shuttling barrier is determined frame by frame until the virtual character leaves the preset special effects rendering range, and the shuttling contact area of ​​each frame matches the shape and action of the virtual character corresponding to the frame.

[0092] In the embodiment of the present application, optionally, determining the shuttle contact area of ​​the virtual character on the target shuttle barrier in step 101 and step 201 includes:

[0093] Step 201-1, photographing the virtual character by an orthogonal projection camera disposed at a photographing position corresponding to the target shuttle barrier, to obtain depth information of each frame of the virtual character;

[0094] Step 201 - 2 : extracting the shuttle contact area of ​​the virtual character on the target shuttle barrier from the depth information according to the distance information corresponding to the depth information.

[0095] In the above embodiment, in the game, an orthogonal projection camera can be pre-created at the shooting position corresponding to the target shuttle barrier, and the orthogonal projection camera can be turned on when the virtual character enters the preset special effect rendering range corresponding to the target shuttle barrier; or when the virtual character enters the preset special effect rendering range corresponding to the target shuttle barrier, the orthogonal projection camera can be created and turned on at the shooting position corresponding to the target shuttle barrier. After turning on the orthogonal projection camera, the virtual character is photographed frame by frame to obtain the depth information of each frame corresponding to the virtual character. In order to ensure that the virtual character can quickly generate the shuttle special effect when shuttling the target shuttle barrier, the preset special effect rendering range can be larger than the preset contact range of the target shuttle barrier, that is, the virtual character is photographed when it enters the preset special effect rendering range, but it is not until the virtual character enters the preset contact range that it is considered that the virtual character has made contact with the target shuttle barrier and the shuttle special effect begins to be displayed. Next, the depth information can characterize the three-dimensional coordinate information of each point on the virtual character model (including the modeling model). By obtaining the depth information, the distance between each point on the virtual character model and the orthogonal projection camera that shoots the virtual character can be known, thereby calculating the distance between each point on the virtual character model and the target shuttle barrier. Further, according to the distance information corresponding to the depth information, the points on the virtual character model that are close to the target shuttle barrier can be extracted from the depth information, and the shuttling contact area of ​​the virtual character with the target shuttle barrier can be determined based on these points.

[0096] In an embodiment of the present application, optionally, step 201-1 includes: determining the shooting position at a preset shooting distance from the target shuttle barrier on a straight line passing through the position of the virtual character and perpendicular to the target shuttle barrier; turning on the orthogonal projection camera at the shooting position, and shooting the virtual character through the orthogonal projection camera to obtain depth information of the virtual character.

[0097] In the above embodiment, if Figure 3 As shown, the straight line formed by the shooting position of the orthogonal projection camera and the position of the virtual character is perpendicular to the target shuttle barrier, and the position of the virtual character is between the shooting position and the target shuttle barrier. Specifically, when it is detected that the virtual character enters the preset special effect rendering range, a point with a preset shooting distance from the target shuttle barrier is found on the straight line passing through the position of the virtual character and perpendicular to the target shuttle barrier as the shooting position, and the pre-created orthogonal projection camera is moved to the position and turned on, or an orthogonal projection camera is created and turned on at the position, so as to shoot the virtual character to obtain depth information.

[0098] In an embodiment of the present application, optionally, step 201-2 includes: drawing a texture map according to the depth information, and determining the distance corresponding to each pixel based on the pixel information of each pixel in the texture map; extracting pixels in the texture map whose distances fall within a preset contact range as contact pixels, and generating a shuttling contact area of ​​the virtual character with respect to the target shuttling barrier based on the pixel information of the contact pixels, wherein the preset contact range is determined based on a preset shooting distance between the shooting position and the target shuttling barrier and a special effect display distance corresponding to the target shuttling barrier.

[0099] In the above embodiment, the depth information can be drawn in the texture map, so as to determine the distance corresponding to each pixel based on the pixel depth information of each pixel in the texture map, and the distance is used to represent the distance from the orthogonal projection camera, and then the pixel corresponding to the pixel falling within the preset contact range is extracted from the texture map as the contact pixel, so as to determine the shuttling contact area of ​​the virtual character to the target shuttling barrier based on the contact pixel, and the shuttling contact area is the area formed by the contact pixel. Specifically, the preset contact range refers to the range in which the virtual character comes into contact with the target shuttling barrier, and the preset contact range covers the range in which the distance from the left and right sides of the target shuttling barrier is not greater than the special effect display distance, that is, the minimum value of the preset contact range is the difference between the shooting distance and the special effect display distance, and the maximum value of the preset contact range is the sum of the shooting distance and the special effect display distance. For example, the orthographic projection camera is placed 10 meters before the target shuttle barrier, and the preset special effect rendering range is 20 meters, that is, the virtual character will be photographed by the camera within 10 meters before and after the target shuttle barrier, and the special effect display distance is 1 meter. Since the distance between the camera and the target shuttle barrier is 10 meters, the depth information rendered into the Render Target texture map is compared with 10 meters. If the depth information is less than 1 meter away from 10 meters (for example, the depth is 9 to 11 meters), it is determined that the current pixel point can be regarded as the area where the player character is in contact with the door.

[0100] Furthermore, in order to reduce the game device cost, it is not necessary to continue to shoot the virtual character with the orthogonal projection camera after the virtual character leaves the preset special effect rendering range. Optionally, when it is detected that the virtual character leaves the preset special effect rendering range, the orthogonal projection camera is turned off.

[0101] Step 202, when the current frame shuttle contact area is the first frame shuttle contact area, display the current frame shuttle special effect of the virtual character on the target shuttle barrier on the target shuttle barrier according to the current frame shuttle contact area.

[0102] In the embodiment of the present application, if the current frame shuttle contact area is the first frame, then the current frame shuttle contact area can be directly used to display the shuttle special effects of the current frame.

[0103] Optionally, step 202 includes: when the current frame shuttling contact area is the first frame shuttling contact area, drawing a current frame shuttling contact map according to the current frame shuttling contact area; drawing the shuttling special effects of the virtual character on the material of the target shuttling barrier according to the current frame shuttling contact map, so as to render the shuttling special effects of the virtual character on the target shuttling barrier on the target shuttling barrier using the drawn material.

[0104] In the above embodiment, for the first frame shuttle contact area, it can be directly drawn as the current frame shuttle contact map, and based on the map, the shuttle special effects are drawn on the material of the target shuttle barrier, so as to use the drawn material to render the virtual character's shuttle special effects on the target shuttle barrier.

[0105] Step 203, when the current frame shuttling contact area is not the first frame shuttling contact area, the current frame shuttling special effects of the virtual character on the target shuttling barrier are displayed on the target shuttling barrier according to the current frame shuttling contact area and the previous frame shuttling contact area, so as to show the contour-related special effects with continuously changing effects left on the target shuttling barrier when the virtual character shuttles.

[0106] In the embodiment of the present application, if the shuttle contact area of ​​the current frame is not the first frame, then in order to show the continuous change effect of the shuttle special effect, the shuttle special effect of the current frame can be displayed based on the fusion effect of the shuttle contact area of ​​the current frame and the shuttle contact area of ​​the previous frame. Figure 4 The figure shows a schematic diagram of a frame of shuttle special effects.

[0107] Optionally, step 203 includes: when the current frame shuttling contact area is not the first frame shuttling contact area, drawing a current frame preliminary shuttling contact map according to the current frame shuttling contact area, and generating a current frame shuttling contact map according to the current frame preliminary shuttling contact map and the previous frame shuttling contact map; drawing the shuttling special effects of the virtual character on the material of the target shuttling barrier according to the current frame shuttling contact map, so as to render the shuttling special effects of the virtual character on the target shuttling barrier on the target shuttling barrier using the drawn material.

[0108] In the above embodiment, for the shuttle contact area that is not the first frame, the current frame shuttle contact area can be first drawn as a current frame preliminary shuttle contact map, and the map is merged with the previous frame shuttle contact map to obtain the current frame shuttle contact map, and then the shuttle special effects are drawn on the material of the target shuttle barrier based on the map, so as to use the drawn material to render the virtual character's shuttle special effects on the target shuttle barrier.
