[0074] The present invention 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.

[0075] At present, only the emission effect of laser virtual objects can be achieved. When the laser virtual objects are blocked by obstacles in the same game scene, the existing technology cannot achieve the effect of the laser virtual objects being blocked.

[0076] In order to solve the above problems, an embodiment of the present invention provides a control method for laser special effects, such as Figure 1 As shown, the method includes:

[0077] 101. Obtain a virtual special effect corresponding to the laser virtual object played at the emission point.

[0078] Among them, laser virtual objects include not only lasers in game scenes, but also all virtual objects with similar characteristics to lasers. Virtual special effects are pre-made by artists, and the style of the virtual special effects is required not to be affected by scaling.

[0079] The embodiment of the present invention is mainly used to control laser special effects to achieve a scene of laser virtual object blocking effect. The execution subject of the embodiment of the present invention is a device or equipment capable of controlling laser special effects, which can be a server or a client.

[0080] For an embodiment of the present invention, when a command to generate a laser virtual object is received, a virtual special effect corresponding to the laser virtual object is obtained, and the virtual special effect is played at the emission point of the laser virtual object, thereby achieving the emission effect of the laser virtual object.

[0081] 102. Perform overlapping detection on the capsule corresponding to the laser virtual object to determine a first target collision body that blocks the virtual special effect in the virtual scene.

[0082] The first target collision body can be a sphere, a capsule, a cuboid, a convex hull grid, etc., and there is only one first target collision body that is finally determined. For the embodiment of the present invention, when the virtual special effect is played, the collision body in the same virtual scene as the laser virtual object may block the virtual special effect. In order to achieve the effect that the laser virtual object is blocked, it is necessary to first screen out the second target collision body that blocks the virtual special effect from the physical level through overlapping detection, and then screen out the first target collision body that blocks the virtual special effect from the logical level in the second target collision body, so as to perform ray detection on the first target collision body.

[0083] Since directly using a large number of rays to detect obstacles that can block virtual special effects will increase detection overhead and reduce detection efficiency, in order to overcome the above-mentioned defects, in the embodiment of the present invention, an overlapping detection method is used to determine the second target collision body that blocks the virtual special effects at the physical level. Specifically, Unity's physics engine Physx can be used for overlapping detection. Since laser virtual objects are mostly straight lines and cylinders of uniform thickness, they can be approximately regarded as capsules. By calling the Physics.OverlapCapsuleNonAlloc interface, the overlapping detection of the capsule corresponding to the laser virtual object and the collision body in the same virtual scene is realized. The collision body can be regarded as a sphere, capsule, cuboid, convex hull mesh, etc. according to the actual shape characteristics. Through this overlapping detection, the second target collision body that blocks the virtual special effects can be screened out from the physical level. It should be noted that Unity's physics engine Physx can support the cache function. Before the physical world in the virtual scene is updated, the detection between the capsule and the same collision body will only be calculated once, and the subsequent calculations will return the previous calculation results.

[0084] Furthermore, the first target collision body that blocks the virtual special effect is determined from the second target collision body at the logical level, so as to perform ray detection on the first target collision body and obtain the intersection point. The specific determination process of the second target collision body and the first target collision body is detailed in steps 202 and 203.

[0085] 103. Launch a ray from the launch point along the launch direction of the laser virtual object to intersect the first target collision body, and obtain an intersection point between the ray and the first target collision body.

[0086] In order to reduce the overhead of ray detection, the embodiment of the present invention only emits one ray to the first target collision body during the ray detection process. Specifically, from the center position of the virtual special effect, only one ray intersecting the first target collision body is emitted along the emission direction of the laser-type virtual object. When the emitted ray intersects with the surface of the first target collision body, the physical engine Physx returns the position information of the intersection. Through the position information of the intersection, the virtual special effect can be scaled and the corresponding collision effect can be played at the same time.

[0087] 104. Based on the distance between the intersection point and the emission point, scale the virtual special effect, and play the collision special effect corresponding to the laser virtual object at the intersection point.

[0088] The collision special effect is a special effect when a capsule body pre-made by an artist collides with a collision body. For the embodiment of the present invention, in order to control the laser special effect to achieve the effect of the laser virtual object being blocked, step 104 specifically includes: calculating the scaling factor corresponding to the virtual special effect according to the distance between the intersection point and the emission point, and the length corresponding to the virtual special effect; based on the scaling factor, scaling the virtual special effect along the emission direction of the laser virtual object.

[0089] Specifically, when the ray intersects with the surface of the first target collision body, the physics engine Physx will return the position information of the intersection point, and determine the distance between the intersection point and the emission point based on the position information of the intersection point and the position information of the emission point. Then, the distance between the intersection point and the emission point is divided by the original length corresponding to the virtual special effect to obtain the scaling factor corresponding to the virtual special effect. Then, according to the scaling factor, the virtual special effect is scaled along the emission direction of the laser virtual object. For example, the scaling factor is 1:2, the original length corresponding to the virtual special effect is 100 meters, and the length corresponding to the virtual special effect after scaling is 50 meters. At the same time, according to the position information corresponding to the intersection point, the collision effect corresponding to the laser virtual object is played at the intersection point. Thus, by scaling the virtual special effect and playing the corresponding collision effect at the intersection point, the effect of the laser virtual object being blocked by the collision body can be achieved.

[0090] In a specific application scenario, after the virtual special effects of the laser virtual object are played and before they are destroyed, it is necessary to perform blocking detection on the capsule body corresponding to the laser virtual object at a certain frequency. Specifically, it can be detected whether the position information of the intersection of the ray and the collision body in each frame image changes. If the position information of the intersection continues to change, the scaling process of the virtual special effect is also ongoing. Based on this, the method includes: when the position information of the intersection changes, determining the changed distance between the changed intersection and the emission point; based on the changed distance and the length corresponding to the virtual special effect, updating the scaling factor corresponding to the virtual special effect; based on the updated scaling factor, scaling the virtual special effect along the emission direction of the laser virtual object, and playing the collision special effect corresponding to the virtual object at the changed intersection.

[0091] A control method for laser special effects provided by an embodiment of the present invention can obtain the virtual special effects corresponding to the laser virtual object played at the emission point compared with the current method of playing virtual special effects only at the emission point of the laser virtual object; and perform overlapping detection on the capsule corresponding to the laser virtual object to determine the first target collision body that blocks the virtual special effects in the virtual scene; at the same time, a ray that intersects with the first target collision body is emitted from the emission point along the emission direction of the laser virtual object, and the intersection of the ray and the first target collision body is obtained; finally, based on the distance between the intersection and the emission point, the virtual special effect is scaled, and the collision special effect corresponding to the laser virtual object is played at the intersection. Thus, by performing overlapping detection on the capsule of the laser virtual object, and filtering out the first target collision body that will block the virtual special effect at the logical level, performing ray detection to obtain the intersection, the corresponding collision special effect can be played at the intersection, and the virtual special effect of the laser virtual object can be scaled, so that the effect of the laser virtual object being blocked can be achieved. At the same time, since only one ray detection is used in the process of obtaining the intersection, the detection overhead can be reduced and the ray detection efficiency can be improved.

[0092] Further, in order to better illustrate the realization process of the laser virtual object blocking effect, as a refinement and extension of the above embodiment, the embodiment of the present invention provides another control method of laser special effects, such as Figure 2 As shown, the method includes:

[0093] 201. Obtain a virtual special effect corresponding to the laser virtual object played at the emission point.

[0094] For an embodiment of the present invention, when a generation instruction of a laser-type virtual object is received, the virtual special effects corresponding to the laser-type virtual object are obtained, and the original length and radius corresponding to the virtual special effects are recorded, and then the virtual special effects are played at the emission point, thereby realizing the emission effect of the laser-type virtual object.

[0095] 202. Determine at least one collision body in the same virtual scene as the laser virtual object, perform overlap detection on the at least one collision body and the capsule body respectively, and determine at least one second target collision body that blocks the virtual special effect at a physical level from the at least one collision body according to the overlap detection result.

[0096] Among them, the number of second target collision bodies can be one, two or more. In order to avoid using a large number of rays to detect the collision body that blocks the virtual special effect and increase the detection overhead, the embodiment of the present invention adopts an overlapping detection method to screen out the second target collision body that blocks the virtual special effect at the physical level. Specifically, in the overlapping detection process, since the laser virtual objects are mostly straight lines and uniformly thick bodies, the laser virtual objects can be regarded as capsules. The size of the capsule can be determined according to the size of the virtual special effect. Based on this, the method includes: adjusting the radius corresponding to the virtual special effect according to a preset proportional coefficient to obtain an adjusted radius; based on the length corresponding to the virtual special effect and the adjusted radius, generating a capsule corresponding to the laser virtual object. Among them, the length of the capsule can be equal to the original length of the virtual special effect, and the radius of the capsule is adjusted to be slightly smaller than the radius of the virtual special effect by a preset proportional coefficient to avoid being considered as blocking once the edge of the virtual special effect intersects with the collision body. The preset proportional coefficient can be set according to actual business needs.

[0097] In the process of performing overlap detection on the capsule of the laser virtual object, Unity provides Layer at the physical engine level to filter the collision body, that is, when calling the interface to detect overlapping collision bodies, only the collision bodies belonging to the specified layer can be detected, and the collision bodies of different layers have different corresponding categories. For example, the collision bodies can be divided into attack collision bodies, hit collision bodies, shield collision bodies, volume collision bodies, etc. according to the categories. The collision bodies of the above categories are all at different levels. In the process of performing overlap detection, the embodiment of the present invention can only perform overlap detection on the collision bodies of the specified layer. Based on this, the overlapping detection is performed on the at least one collision body and the capsule body respectively, and the second target collision body that blocks the virtual special effect at the physical level is determined from the at least one collision body according to the overlapping detection result, including: judging whether any one of the at least one collision body belongs to the target level according to the level information corresponding to the any one collision body; if the any one collision body belongs to the target level, performing overlap detection on the any one collision body and the capsule body; if the any one collision body overlaps with the capsule body, determining the any one collision body as the second target collision body. Among them, the target level can be set according to actual business needs, and the number of target levels is at least one.

[0098] For example, the physics engine is set to detect only two layers of collision bodies, and the collision bodies at the target level are the struck collision body and the shield collision body. At least one collision body in the same virtual scene as the laser virtual object includes: collision body A, collision body B and collision body C. Collision body A is an attack collision body, collision body B is a struck collision body, and collision body C is a shield collision body. In the process of detecting collision body A, collision body B and collision body C, it is first determined whether collision body A, collision body B and collision body C belong to the target level. Since collision body A is an attack collision body and does not belong to the target level, it is not overlapped. It is assumed that it will not block the virtual special effects of the laser virtual object. In addition, since collision body B and collision body C are the hit collision body and the shield collision body respectively, both of which belong to the collision bodies at the target level, overlap detection is performed on collision body B and collision body C respectively. Furthermore, in the process of overlap detection, if the capsule body of the laser virtual object overlaps with collision body B, it is determined that collision body B is the second target collision body that can block the virtual special effects at the physical level. Similarly, it can be determined whether collision body C is the second target collision body.

[0099] 203. Determine a first target collision body among the at least one second target collision body that blocks the virtual special effect at a logical level according to the distances between the at least one second target collision body and the capsule body.

[0100] For the embodiment of the present invention, not all collision bodies in the target layer can block the virtual special effect, and it is necessary to further determine the first target collision body that can block the virtual special effect at the logical level. Specifically, when determining the first target collision body, at least one second target collision body can be sorted according to the distance between at least one second target collision body and the capsule body, and then according to the sorting result, it is determined in turn at the layer logical level whether the second target collision body can block the virtual special effect. Based on this, step 203 specifically includes: sorting the at least one second target collision body from near to far according to the distance between the at least one second target collision body and the capsule body respectively, to obtain a sorting result; according to the sorting result, determining in turn whether the at least one second target collision body can block the virtual special effect at the logical level; when it is determined that the first second target collision body that can block the virtual special effect at the logical level is the first target collision body, the determination process is stopped, and the first second target collision body that can block the virtual special effect at the logical level is determined as the first target collision body.

[0101] For example, the second target collision bodies screened out from the physical level include collision body D, collision body E and collision body F. According to the distance between the above collision bodies and the capsule body, collision body D, collision body E and collision body F are sorted from near to far, and the sorting results are collision body E, collision body D and collision body F. Then, according to the above sorting results, it is determined from the logical level whether collision body E, collision body D and collision body F can block the virtual special effect. If collision body E cannot block the virtual special effect at the logical level, it is continued to be determined whether collision body D can block the virtual special effect at the logical level according to the sorting order. If it is determined that collision body D can block the virtual special effect at the logical level, collision body D is determined to be the first target collision body, and collision body F is no longer determined subsequently.

[0102] In a specific application scenario, the determination logic may be set according to actual business needs, such as determining whether the second target collision body can block the virtual special effect at a logical level through the attribute information corresponding to the capsule body and the attribute information corresponding to the second target collision body, where the attribute information may specifically be organizational information (for example, camp attribute). When the capsule body and the second target collision body belong to different organizational information, it is determined that the second target collision body can block the virtual special effect at a logical level. Based on this, determining the first target collision body that blocks the virtual special effect at a logical level in the at least one second target collision body according to the distance between the at least one second target collision body and the capsule body respectively includes: determining whether the any one of the at least one second target collision bodies can block the virtual special effect at a logical level according to the attribute information corresponding to the second target collision body and the attribute information corresponding to the laser virtual object. Further, the determining whether any one of the at least one second target collision body can block the virtual special effect at a logical level according to the attribute information corresponding to the second target collision body and the attribute information corresponding to the laser-type virtual object includes: determining whether any one of the second target collision body can block the virtual special effect at a logical level according to the organization information of the character to which the any one of the second target collision body belongs and the organization information of the character that emits the laser-type virtual object; if the organization information of the character to which the any one of the second target collision body belongs is the same as the organization information of the character that emits the laser-type virtual object, determining that the any one of the second target collision body cannot block the virtual special effect at a logical level; if the organization information of the character to which the any one of the second target collision body belongs is different from the organization information of the character that emits the laser-type virtual object, determining that the any one of the second target collision body can block the virtual special effect at a logical level.

[0103] For example, when the camp of the character to which any second target collision body belongs is the same as the camp of the character that emits the laser-type virtual object, it is determined that any second target object will not block the virtual special effects of the laser-type virtual object; when the camp of the character to which any second target collision body belongs is different from the camp of the character that emits the laser-type virtual object, it is determined that any second target object will block the virtual special effects of the laser-type virtual object.

[0104] It should be noted that the embodiment of the present invention does not limit the specific logic of the determination. In addition to the above-mentioned determination of the tissue information of the capsule body and the second target collision body, it is also possible to detect whether the second target collision body itself is configured to allow blocking of the laser, or to detect whether the laser-type virtual object itself is configured to be blocked, etc.

[0105] 204. Launch a ray from the launch point along the launch direction of the laser virtual object to intersect the first target collision body, and obtain an intersection point between the ray and the first target collision body.

[0106] For the embodiment of the present invention, only one ray intersecting with the first target collision body is emitted from the center position of the virtual special effect along the emission direction of the laser-type virtual object. When the emitted ray intersects with the surface of the first target collision body, the physical engine Physx returns the position information of the intersection so that the virtual special effect can be scaled based on the position information of the intersection and the corresponding collision special effect can be played at the same time.

[0107] 205. Based on the distance between the intersection point and the emission point, scale the virtual special effect, and play the collision special effect corresponding to the laser virtual object at the intersection point.

[0108] The process of scaling the virtual special effects and the process of playing the collision special effects at the intersection in the embodiment of the present invention are substantially the same as step 104 and will not be described in detail herein.

[0109] Another control method for laser special effects provided by an embodiment of the present invention can obtain the virtual special effects corresponding to the laser virtual object played at the emission point compared with the current method of playing virtual special effects only at the emission point of the laser virtual object; and perform overlapping detection on the capsule corresponding to the laser virtual object to determine the first target collision body that blocks the virtual special effects in the virtual scene; at the same time, a ray that intersects with the first target collision body is emitted from the emission point along the emission direction of the laser virtual object, and the intersection of the ray and the first target collision body is obtained; finally, based on the distance between the intersection and the emission point, the virtual special effect is scaled, and the collision special effect corresponding to the laser virtual object is played at the intersection. Thus, by performing overlapping detection on the capsule of the laser virtual object, and filtering out the first target collision body that will block the virtual special effect at the logical level, performing ray detection to obtain the intersection, the corresponding collision special effect can be played at the intersection, and the virtual special effect of the laser virtual object can be scaled, so that the effect of the laser virtual object being blocked can be achieved. At the same time, since only one ray detection is used in the process of obtaining the intersection, the detection overhead can be reduced and the ray detection efficiency can be improved.

[0110] Further, as Figure 1 The specific implementation of the present invention provides a control device for laser special effects, such as Figure 3 As shown, the device includes: an acquisition unit 31, a detection unit 32, a transmission unit 33 and a scaling unit 34.

[0111] The acquisition unit 31 may be used to acquire virtual special effects corresponding to the laser virtual object played at the emission point.

[0112] The detection unit 32 may be used to perform overlapping detection on the capsule corresponding to the laser virtual object, and determine the first target collision body that blocks the virtual special effect in the virtual scene.

[0123] Furthermore, the detection unit 32 further includes: an adjustment module 323 and a generation module 324 .

[0124] The adjustment module 323 may be used to adjust the radius corresponding to the virtual special effect according to a preset proportional coefficient to obtain an adjusted radius.

[0125] The generating module 324 may be configured to generate a capsule body corresponding to the laser-type virtual object based on the length corresponding to the virtual special effect and the adjusted radius.

[0126] Furthermore, the first determination module 321 includes: a sorting submodule, a second judging submodule and a second determining submodule.

[0127] The sorting submodule may be used to sort the at least one second target collision body from near to far according to the distances between the at least one second target collision body and the capsule body, to obtain a sorting result.

[0128] The second determination submodule may be configured to determine, in order according to the sorting result, whether the at least one second target collision body can block the virtual special effect at a logical level.

[0129] The second determination submodule may be configured to stop the determination process when determining the first second target collision body that can logically block the virtual special effect, and determine the first second target collision body that can logically block the virtual special effect as the first target collision body.

[0130] Furthermore, the second determination submodule can be specifically used to determine whether any one of the at least one second target collision body can block the virtual special effect at a logical level based on the attribute information corresponding to the any one of the at least one second target collision body and the attribute information corresponding to the laser virtual object.

[0131] Furthermore, the second determination submodule can also be specifically used to determine whether any one of the second target collision bodies can block the virtual special effect at a logical level based on the organizational information of the character to which the any one of the second target collision bodies belongs and the organizational information of the character that emits the laser-type virtual object; if the organizational information of the character to which the any one of the second target collision bodies belongs is different from the organizational information of the character that emits the laser-type virtual object, it is determined that any one of the second target collision bodies can block the virtual special effect at a logical level.

[0132] In a specific application scenario, the scaling unit 34 includes: a calculation module 341 and a scaling module 342 .

[0133] The calculation module 341 may be configured to calculate a scaling factor corresponding to the virtual special effect according to a distance between the intersection point and the emission point and a length corresponding to the virtual special effect.

[0134] The scaling module 342 may be configured to scale the virtual special effect along the emission direction of the laser-like virtual object based on the scaling factor.

[0135] Furthermore, the scaling unit 34 further includes: a second determining module 343 and an updating module 344 .

[0136] The second determining module 343 may be configured to determine a changed distance between the changed intersection and the transmitting point when the position information of the intersection changes.

[0137] The updating module 344 may be configured to update a scaling factor corresponding to the virtual special effect based on the changed distance and the length corresponding to the virtual special effect.

[0138] The scaling module 342 may also be used to scale the virtual special effects along the emission direction of the laser-type virtual object based on the updated scaling factor, and play the collision special effects corresponding to the virtual object at the changed intersection.

[0139] It should be noted that for other corresponding descriptions of the functional modules involved in the control device for laser special effects provided in the embodiment of the present invention, reference can be made to Figure 1 The corresponding description of the method shown will not be repeated here.

[0140] Based on the above Figure 1 The method shown, accordingly, an embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented: obtaining a virtual special effect corresponding to a laser virtual object played at a launch point; performing overlap detection on a capsule corresponding to the laser virtual object, and determining a first target collision body in a virtual scene that blocks the virtual special effect; emitting a ray that intersects with the first target collision body from the launch point along the launch direction of the laser virtual object, and obtaining an intersection point of the ray and the first target collision body; scaling the virtual special effect based on the distance between the intersection point and the launch point, and playing the collision special effect corresponding to the laser virtual object at the intersection point.

[0141] Based on the above Figure 1 The method shown and Figure 3 The embodiment of the device shown in the figure, the embodiment of the present invention also provides a physical structure diagram of a computer device, such as Figure 5 As shown, the computer device includes: a processor 41, a memory 42, and a computer program stored in the memory 42 and executable on the processor, wherein the memory 42 and the processor 41 are both arranged on a bus 43, and when the processor 41 executes the program, the following steps are implemented: obtaining a virtual special effect corresponding to a laser virtual object played at a launch point; performing overlap detection on a capsule corresponding to the laser virtual object, and determining a first target collision body in a virtual scene that blocks the virtual special effect; emitting a ray that intersects with the first target collision body from the launch point along the launch direction of the laser virtual object, and obtaining an intersection point between the ray and the first target collision body; scaling the virtual special effect based on a distance between the intersection point and the launch point, and playing a collision special effect corresponding to the laser virtual object at the intersection point.

[0142] Through the technical solution of the present invention, it is possible to obtain the virtual special effects corresponding to the laser virtual object played at the emission point; and perform overlapping detection on the capsule body corresponding to the laser virtual object to determine the first target collision body that blocks the virtual special effects in the virtual scene; at the same time, a ray that intersects with the first target collision body is emitted from the emission point along the emission direction of the laser virtual object, and the intersection of the ray and the first target collision body is obtained; finally, based on the distance between the intersection and the emission point, the virtual special effects are scaled, and the collision special effects corresponding to the laser virtual object are played at the intersection. Thus, by performing overlapping detection on the capsule body of the laser virtual object, and filtering out the first target collision body that will block the virtual special effects at the logical level, performing ray detection to obtain the intersection, the corresponding collision special effects can be played at the intersection, and the virtual special effects of the laser virtual object can be scaled, so that the effect of the laser virtual object being blocked can be achieved. At the same time, since only one ray detection is used in the process of obtaining the intersection, the detection overhead can be reduced and the ray detection efficiency can be improved.
