[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. At the same time, in the description of the embodiments of the present application, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] Embodiments of the present application provide a virtual object shaking control method, device, electronic device, and computer-readable storage medium.

[0034] Specifically, this embodiment will be described from the perspective of a virtual object shaking control device, which can be integrated into an electronic device, that is, the virtual object shaking control method of the embodiment of the present application can be executed by an electronic device, and optionally, the electronic device can include: a terminal device. The terminal device can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop computer, a game console, or a personal computer (PC) and other devices.

[0035] The virtual object shaking control method provided in the embodiment of the present application can be applied to a virtual object shaking control system. The virtual object shaking control system may include a player terminal device and a server, and the terminal may be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. The player terminal device and the server may perform two-way communication via a network.

[0036] Optionally, the electronic device may be a server, which may be an independent server, or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of a plurality of servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0037] In one embodiment of the present application, the virtual object shaking control method can be run on a local terminal device or a server. When the virtual object shaking control method is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0038] In an optional implementation, various cloud applications can be run under the cloud interaction system, such as cloud games. Taking cloud games as an example, cloud games refer to a game mode based on cloud computing. In the operation mode of cloud games, the operating body of the game program and the main body of the game screen presentation are separated. The storage and operation of the interactive method in the game are completed on the cloud game server. The client device is used for receiving and sending data and presenting the game screen. For example, the client device can be a display device with data transmission function close to the user side, such as a mobile terminal, a TV, a computer, a handheld computer, etc.; but the cloud game server in the cloud is used for information processing. When playing the game, the player operates the client device to send an operation instruction to the cloud game server. The cloud game server runs the game according to the operation instruction, encodes and compresses the game screen and other data, and returns it to the client device through the network. Finally, the client device decodes and outputs the game screen.

[0039] In an optional embodiment, taking a game as an example, a local terminal device stores a game program and is used to present a game screen. The local terminal device is used to interact with the player through a graphical user interface, that is, the game program is downloaded and installed by an electronic device and run conventionally. The local terminal device may provide the graphical user interface to the player in a variety of ways, for example, it may be rendered and displayed on a display screen of the terminal, or provided to the player through a holographic projection. For example, the local terminal device may include a display screen and a processor, the display screen is used to present a graphical user interface, the graphical user interface includes a game screen, and the processor is used to run the game, generate a graphical user interface, and control the display of the graphical user interface on the display screen.

[0040] The following is a detailed description in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0041] The first aspect of the present application embodiment provides a virtual object shaking control method, please refer to Figure 1 The specific process of the virtual object shaking control method may be as follows: Step 101 to Step 106:

[0042] Step 101: Obtain a UV map of each virtual object in the virtual object combination in a first UV coordinate system.

[0043] The virtual object combination includes a plurality of virtual objects, and the virtual objects are objects that need to be shaken. Specifically, in this embodiment, the virtual objects in the virtual object combination are shaken to achieve a wave-like shaking effect of the entire virtual object combination, and the shaking effects of the individual virtual objects are different to a certain extent, and the individual virtual objects cooperate with each other to make the overall shaking effect of the virtual object combination have a certain regularity, so that a more realistic shaking animation effect can be obtained, and the user's gaming experience can be improved.

[0044] In a specific application scenario, the virtual object combination can be a software such as an animal, a person, or clothes, and a better shaking animation effect can be obtained according to the virtual object shaking control method in the embodiment of the present application. For example, when the virtual object combination is an animal, the virtual object can be the hair of the animal. The virtual object shaking control method according to the embodiment of the present application can flexibly control a large number of hairs, and can also achieve a fixed effect of the virtual object contact position (such as the hair root), thereby achieving a better animation effect.

[0045] It should be noted that the above-mentioned virtual object is a three-dimensional model in a three-dimensional coordinate system. In the embodiment of the present application, the three-dimensional model is mapped to the UV coordinate system (i.e., UV space) to obtain the UV map of the virtual object, and there is a mapping relationship between the UV map and the vertices of the three-dimensional model. Therefore, the displacement offset of each vertex of the three-dimensional model can be calculated based on the UV map, thereby realizing the shaking control of the three-dimensional model of the virtual object. The above-mentioned vertex is a point of the three-dimensional model in the three-dimensional coordinate space, which contains information about the normal direction, texture coordinates and other mesh attributes.

[0046] Optionally, the step of obtaining a UV map of each virtual object in the virtual object combination in the first UV coordinate system includes:

[0047] Perform front view projection on each virtual object in the virtual object combination to obtain a UV map of each virtual object in the first UV coordinate system.

[0048] The first UV coordinate system is a coordinate system used to perform UV unfolding of a three-dimensional model to obtain a UV map. Specifically, by performing front view projection on a virtual object combination, the UV map can be made consistent with the silhouette of each virtual object in the front view, thereby making it more convenient and flexible to perform shaking control. In this embodiment, the front view projection of a virtual object is used as an example for specific description, but it is not a specific limitation. In actual use, projection can also be performed from other views.

[0049] Step 102: compress the UV maps of the virtual objects to obtain UV lines corresponding to the virtual objects.

[0050] Based on the UV map obtained in step 101, which is consistent with the silhouette of the virtual object front view, in this embodiment, the UV map is compressed to obtain UV lines with only height, so as to improve the efficiency and flexibility of subsequent calculation of displacement offset. And the displacement offset obtained by the same virtual object in the virtual object combination can be kept consistent, showing an overall regular shaking.

[0051] In this embodiment, the arrangement of virtual objects in the horizontal direction is taken as an example for specific description, that is, in the virtual object combination, each virtual object is arranged in the horizontal direction, and the extension direction of the virtual object itself is the vertical direction, and the bottom of the virtual object in the vertical direction is the fixed position of the virtual object (that is, the position in contact with other objects). At this time, the UV map of each virtual object is compressed from both sides to the middle along the horizontal direction to obtain the above-mentioned UV lines. Among them, the above-mentioned horizontal direction is the direction along the horizontal axis of the first UV coordinate system, and the above-mentioned vertical direction is the direction along the vertical axis of the first UV coordinate system.

[0052] Step 103: save the UV lines into a second UV coordinate system according to the arrangement positions of the virtual objects in the virtual object combination.

[0053] Among them, the above-mentioned second UV coordinate system is a pre-set coordinate system for saving the sorted UV lines. It should be noted that the above-mentioned first UV coordinate system is used for texture sampling (i.e. UV unfolding) of the three-dimensional model. There is a mapping relationship between the UV texture and UV lines in the first UV coordinate system and the vertices of the three-dimensional model. If the position of the UV lines is moved in the first UV coordinate system, the mapping relationship will become complicated, making the subsequent control process more complicated. Therefore, in order to reduce the complexity of the mapping relationship, in this embodiment, the second UV coordinate system is used to calculate the offset during the shaking control process. However, in actual use, the UV lines can also be sorted directly in the first UV coordinate system, which is not specifically limited here.

[0054] Specifically, the first UV coordinate system and the second UV coordinate system are both two-dimensional coordinate systems with a horizontal axis value range from 0 to 1 and a vertical axis value range from 0 to 1. The position of the virtual object in the virtual object combination is fixed, and the arrangement order of each UV line can be determined according to the position of the virtual object in the virtual object combination and a specified sorting direction (e.g., left first, then right, top first, then bottom), and then saved in the second UV coordinate system.

[0055] Figure 2 is a schematic diagram of a UV line saved in a second UV coordinate system provided by an embodiment of the present application, such as Figure 2 As shown, each UV line is sequentially stored in the second UV coordinate system along the horizontal direction (ie, the horizontal axis direction of the second coordinate system).

[0056] Optionally, compressing the UV maps of the virtual objects to obtain UV lines corresponding to the virtual objects includes:

[0057] According to the arrangement direction of the virtual objects in the virtual object combination, the UV map of each of the virtual objects is compressed to obtain UV lines corresponding to each of the virtual objects;

[0058] The step of saving the UV lines into the second UV coordinate system according to the arrangement positions of the virtual objects in the virtual object combination includes:

[0059] According to the arrangement position of each of the virtual objects in the virtual object combination, each of the UV lines is saved in the second UV coordinate system in a manner of being arranged along the horizontal axis of the second UV coordinate.

[0060] Wherein, the bottom end of each of the above UV lines intersects with the horizontal axis of the above second UV coordinate system. Figure 2As shown, each UV line intersects the horizontal axis of the second UV coordinate system perpendicularly to better calculate the displacement offset.

[0061] In one application scenario, considering that the direction in which the virtual objects are arranged in the virtual combination is not necessarily in the horizontal direction, the corresponding virtual object's own extension direction is not necessarily in the vertical direction. For example, each virtual object in the virtual object combination is arranged in the vertical direction, and each virtual object's own extension direction is the horizontal direction. At this time, the UV map of the virtual object is compressed in combination with the direction in which the virtual objects are arranged in the virtual object combination and / or the extension direction of the virtual objects themselves, so as to obtain a better compression effect and improve the convenience in the subsequent shaking control process.

[0062] Furthermore, in the process of saving the UV lines to the second UV coordinate system after compression, the UV lines can be rotated and saved in the second UV coordinate system in a manner arranged along the horizontal axis of the second UV coordinate system to ensure that the bottom end of the UV lines intersects perpendicularly with the horizontal axis of the second UV coordinate system.

[0063] It should be noted that a certain interval is maintained between two adjacent UV lines in the second UV coordinate system, and the specific intervals may be the same or different. In one application scenario, the intervals in the second UV coordinate system are the same and are determined according to the number of UV lines, that is, the UV lines are evenly distributed and stored in the second UV coordinate system. In another application scenario, the interval between two adjacent UV lines in the second UV coordinate system is determined according to the distance between the corresponding two virtual objects in the virtual object combination. The closer the distance between the two virtual objects, the smaller the interval corresponding to them. In this way, the shaking amplitude between virtual objects that are closer is closer, and a more realistic shaking animation effect can be obtained.

[0064] Step 104: According to the horizontal coordinates of the UV lines in the second UV coordinate system and the time parameter, a displacement offset of each of the UV lines is obtained through a preset periodic function, wherein the displacement offset changes back and forth with time within a period of the periodic function.

[0065] Among them, the above-mentioned UV lines intersect perpendicularly with the horizontal axis of the above-mentioned second UV coordinate system, so for each UV line, the horizontal coordinate corresponding to each point on it is the same. Different UV lines are arranged along the horizontal axis direction of the second UV coordinate system, and the horizontal coordinates of each UV line increase from left to right along the horizontal axis of the second UV coordinate system. The above-mentioned preset periodic function is a pre-set periodic function for calculating the displacement offset. The specific function can be set and adjusted according to actual needs. The above-mentioned displacement offset is a parameter for the movement distance during the shaking process.

[0066] In this embodiment, the displacement offset changes back and forth with time within a function period of the periodic function. It should be noted that the time parameter can be used as a part of the independent variable of the periodic function, so the function value of the periodic function will change back and forth with the time parameter. Specifically, the function value of the periodic function changes back and forth once within a preset offset range as the independent variable changes, the minimum value of the preset offset range is less than 0, and the maximum value of the preset offset range is greater than 0. In this way, it is possible to control the virtual object to shake back and forth within each period to obtain a better shaking effect.

[0067] Optionally, the displacement offset of each UV line is obtained by a preset periodic function according to the horizontal coordinate of the UV line in the second UV coordinate system and the time parameter, including:

[0068] Determine a first displacement distance control parameter of each of the UV lines according to the horizontal coordinate of the UV line in the second UV coordinate system, and determine a second displacement distance control parameter of each of the UV lines according to the time parameter;

[0069] The displacement offset of each of the UV lines is obtained by calculating the periodic function according to the first displacement distance control parameter and the second displacement distance control parameter.

[0070] Optionally, the sum of the first displacement distance control parameter and the second displacement distance control parameter is used as the independent variable of the periodic function, and the function value corresponding to the periodic function is used as the displacement offset of the UV line. In actual use, the difference between the first displacement distance control parameter and the second displacement distance control parameter can also be used as the independent variable of the periodic function, and the independent variable of the periodic function can also be determined by other calculation methods, which are not specifically limited here.

[0071] Optionally, the determining of the first displacement distance control parameter of each of the UV lines according to the horizontal coordinate of the UV line in the second UV coordinate system, and the determining of the second displacement distance control parameter of each of the UV lines according to the time parameter include:

[0072] Obtain displacement cycle frequency parameters and displacement speed parameters;

[0073] Determine the first displacement distance control parameter of the UV line according to the product of the abscissa of the UV line in the second UV coordinate system and the displacement cycle frequency parameter;

[0074] The second displacement distance control parameter of the UV line is determined according to the product of the time parameter and the displacement speed parameter.

[0075] Among them, the displacement cycle frequency parameter is a parameter used to control the frequency of the reciprocating change of the displacement offset, and the above-mentioned displacement speed parameter is a parameter used to control the changing speed of the displacement offset. The above-mentioned displacement cycle frequency parameter and displacement speed parameter can be pre-set or adjusted in real time according to actual needs, and are not specifically limited here.

[0076] Step 105: adjusting the displacement offset based on the vertical coordinate of the UV line in the second UV coordinate system to obtain the adjusted displacement offset of each UV line, wherein the adjusted displacement offset at each height of each UV line decreases as the height decreases, and the adjusted displacement offset at the lowest height of each UV line is 0.

[0077] Specifically, in this embodiment, the height information of the UV lines is used as a mask, so that the lower the height, the smaller the shaking amplitude, thereby obtaining a better shaking effect, and the calculation process is simple, convenient and flexible.

[0078] Optionally, before step 105, the method further includes:

[0079] Stretch each of the above UV lines to be the same height as the vertical axis of the UV coordinate system where it is located;

[0080] The above-mentioned displacement offset is adjusted based on the ordinate of the above-mentioned UV line to obtain the adjusted displacement offset of each of the above-mentioned UV lines, including:

[0081] The displacement offset of each UV line at each height is multiplied by the ordinate corresponding to the height in the second UV coordinate system to obtain the adjusted displacement offset of each UV line as it changes with height.

[0082] The stretching of the UV lines can be performed in the first UV coordinate system or in the second UV coordinate system, which is not specifically limited here. In this embodiment, the stretching of the UV lines in the second UV coordinate system is taken as an example for specific description. Figure 2 As shown, Figure 2 Each UV line in the image has been stretched to the same height as the vertical axis height of the second UV coordinate system. In this way, the vertical coordinates of each point in the UV line can be directly used as a mask to adjust the displacement offset, so that the adjusted displacement offset at the lowest height of each UV line is 0, which is conducive to simplifying the calculation process and improving the efficiency of shaking control.

[0083] It should be noted that, for any UV line, the displacement offsets corresponding to points at different heights are the same, and after the offsets are adjusted, the adjusted displacement offsets corresponding to points at different heights are different.

[0084] Step 106: Control the displacement of the model vertices of the virtual object corresponding to the height of the UV line according to the adjusted displacement offset at each height of the UV line.

[0085] Specifically, according to the mapping relationship between the three-dimensional model of the virtual object and the UV map, the adjusted displacement offset corresponding to the model vertices of the virtual object can be determined, so as to control the displacement of the model vertices and realize the back-and-forth shaking animation effect of the virtual object.

[0086] In this embodiment, Figure 2 As shown, a UV line includes multiple mapping points, and a mapping point corresponds to at least one model vertex of the virtual object corresponding to the UV line. The displacement of the corresponding model vertex is controlled according to the adjusted displacement offset of the mapping point.

[0087] In an application scenario, a specific displacement direction may be determined, and the calculated displacement offset is the value of the displacement along the specific displacement direction. It should be noted that, in this embodiment, if no clear displacement direction is specified, a default direction pre-set by the user is used as the specific displacement direction. For example, the default direction may be set to the horizontal direction of the front view of the virtual object combination.

[0088] Optionally, the above-mentioned obtaining of the displacement cycle frequency parameter and the displacement speed parameter includes:

[0089] Acquire a displacement cycle frequency parameter and a displacement speed parameter in a target displacement direction, wherein the target displacement direction includes at least one coordinate axis direction in the coordinate system where the virtual object is located;

[0090] The controlling of displacement of the model vertices of the virtual object corresponding to the height of the UV line according to the adjusted displacement offset at each height of the UV line includes:

[0091] According to the adjusted displacement offset of the UV line at each height in the target displacement direction, the model vertices of the virtual object corresponding to the height of the UV line are controlled to be displaced along the target displacement direction.

[0092] The target displacement direction is the direction in which the displacement of the virtual object needs to be controlled. In this embodiment, the shaking control can be performed for at least one target displacement direction. If there are multiple target displacement directions, the displacement control of the multiple target displacement directions will be superimposed and implemented on the model vertices of the virtual object. For each target displacement direction, the corresponding displacement cycle frequency parameter and displacement speed parameter are obtained respectively, so as to calculate the displacement offset corresponding to each target displacement direction, and then obtain the adjusted displacement offset corresponding to each target displacement direction, so as to realize the displacement control for multiple displacement directions.

[0093] In this embodiment, the virtual object control method is described in detail based on a specific application scenario. Specifically, a sine function (ie, sin function) is selected as a periodic function for calculating the displacement offset. Figure 3 is a schematic diagram of a sine function provided in an embodiment of the present application, such as Figure 3 As shown, the function value of the sine function ranges from -1 to 1. By calculating the displacement offset according to the sine function, the back-and-forth swinging effect can be well achieved, wherein a negative number represents a displacement along the negative direction of the target displacement direction, and a positive number represents a displacement along the positive direction of the target displacement direction.

[0094] In this embodiment, three target displacement directions are set, namely, the directions corresponding to the x-axis, y-axis, and z-axis in the three-dimensional coordinate system where the three-dimensional model of the virtual object is located. For the three target displacement directions, three sets of displacement cycle frequency parameters and displacement speed parameters need to be set. Therefore, in this embodiment, Float3 is used to define the corresponding parameters to more conveniently call the parameters corresponding to the three target displacement directions and reduce unnecessary parameter naming. For example, the displacement cycle frequency parameter can be defined as Float3_Frequency, and the displacement speed parameter can be defined as Float3_Speed. It should be noted that the use of Float3 to define parameters actually includes 3 specific values, for example Float3_Frequency = (A, B, C), A, B and C are the values ​​of the displacement cycle frequency parameters in the three target displacement directions, respectively.

[0095] According to the horizontal coordinate uv.x of the above-mentioned UV line in the second UV coordinate system, combined with the above-mentioned displacement cycle frequency parameter and displacement speed parameter, the corresponding displacement offset can be calculated through the sine function. For example, by defining the target horizontal coordinate Float_Vector = uv.x, the sin function can be called to calculate the displacement offset in each target displacement direction: Float3 offset = sin(_Vector*_Frequency+_GameTime*_Speed). Among them, Float3 offset includes the displacement offset in three target displacement directions, _GameTime is the time parameter. In this embodiment, the game running time is used as the time parameter, and the calculation is combined with the game running time to achieve the animation effect of the virtual object shaking back and forth over time.

[0096] In one application scenario, a displacement distance multiplier Float3_Strength in each target displacement direction may also be defined. The above displacement distance multiplier may be used to adjust and update the displacement offset. For example, directly multiplying the displacement offset by the above displacement distance multiplier may adjust the value of the displacement offset originally ranging from -1 to 1. The value of the above displacement distance multiplier may be set and adjusted according to actual needs and is not specifically limited here.

[0097] In this embodiment, in order to clearly see the displacement control effect of the displacement offset on the virtual object, color rendering is used for exemplary display. Figure 4 is a schematic diagram of the effect of color rendering of a virtual object according to a displacement offset provided by an embodiment of the present application, Figure 5 is a schematic diagram of the effect of controlling the displacement of a virtual object according to a displacement offset provided by an embodiment of the present application.
