[0055] Next, as Figure 1 Taking the electronic device 1000 as an example, various embodiments of the method for generating an image of a virtual character are described.

[0056] <First embodiment>

[0057] Figure 2 A method for generating an image of a virtual character according to some embodiments is shown. The method for generating an image of a virtual character may include the following steps S210 to S240:

[0058] Step S210 : In response to the user's editing operation on the target virtual group, determining an editing identifier indicated by the editing operation.

[0059] In this embodiment, the editing operation may involve the user setting the target virtual group's group formation, individual models, and display actions in the tool bar of the game engine editor. The virtual group here is generally composed of multiple virtual characters, and the group formation of the virtual group may be multiple virtual characters arranged in fixed positions. For example, if there are 9 virtual characters lined up in a row with a distance unit of 1, the group formation is a 9×1 formation.

[0060] In this embodiment, the editing identifier can be a group formation ID, an individual model ID, and an action ID. Different group formation IDs correspond to different group formations. For example, the group formation ID ZX01 corresponds to a 9×1 formation, and the group formation ID ZX02 corresponds to a 3×3 formation. Different individual model IDs correspond to different individual models. For example, the individual model ID MD1 corresponds to an infantryman, and the individual model ID MD2 corresponds to a spearman. Different action IDs correspond to different display actions. For example, the display action corresponding to the action ID DZ1 is slashing, and the display action corresponding to the action ID DZ2 is retreating.

[0061] Step S220: determining a first angle of the target virtual group in a first angle interval according to the editing identifier.

[0062] In this embodiment, the first angle interval may be an angle range, such as [0, 360°), and the first angle is an angle in [0, 360°), such as 5° or 100°.

[0063] Step S230: input the first angle into a preset direction mapping model to obtain a reference direction of the target virtual group.

[0064] In some embodiments, in order to obtain a reference direction, a direction mapping model may be used. The direction mapping model may include:

[0065] DirectionID=((Angel+22.5) / 45)%8+1

[0066] Where DirectionID is the reference direction, Angel is the first angle, and % is the modulo operation.

[0067] In this embodiment, if Figure 3 As shown, the reference direction is automatically mapped to 1-8, formatted with zero padding to 3 digits, such as 1→001. With a step size of 45°, each angle interval includes ±22.5° from the center point, for a total of 8 directions, 001-008, covering the full viewing angle. When the first angle is 22.5°, the reference direction can be 002.

[0068] Step S240 : determining a first two-dimensional image of the target virtual group according to the configuration information and reference direction of the target virtual group indicated by the editing mark.

[0069] In this embodiment, the configuration information may include relative position information of each virtual character in the target virtual group, individual models of each virtual character, and display actions of each virtual character.

[0070] In this embodiment, the first two-dimensional image may be a two-dimensional picture generated by encoding in a PNG format.

[0071] The method for generating images of virtual characters according to the first embodiment of the present invention solves the problem in the prior art that, when a user needs to generate animations of virtual scenes with a large number of virtual characters, the user needs to repeatedly adjust the camera position of the virtual scene before generating the corresponding animation, which greatly increases the user's workload. Based on this method, in response to the user's editing operation, an editing identifier indicating the editing operation is determined. Based on the editing identifier, a first angle of the target virtual group in a first angle interval is determined. Then, through a direction mapping model, a reference direction matching the first angle is determined. The first two-dimensional image of the target virtual group is determined based on the reference direction and the configuration information of the target virtual group. This enables the user to generate a first two-dimensional image that meets the user's needs through simple input, thereby improving the output efficiency of the first two-dimensional image and reducing the user's workload.

[0072] <Second embodiment>

[0073] In this embodiment, in order to adapt to the editing settings of different users, the editing identifier may include the input second angle. According to different editing settings, the input second angle may be converted into a first angle that conforms to the first angle range.

[0074] In these embodiments, relative to the first embodiment, step S220 may include the following steps S310 and S320:

[0075] Step S310: Determine a second angle interval of a second angle.

[0076] In this embodiment, different user editing settings may correspond to different second angle ranges, for example, the second angle range is [-30, 330°).

[0077] Step S320: Convert the second angle into a first angle matching the first angle range according to the interval difference between the first angle interval and the second angle interval.

[0078] In some examples, the second angle is -30°, the first angle interval is [0, 360°), the second angle interval is [-30, 330°), and the interval difference is 30°, then the first angle is 0°.

[0079] <Third embodiment>

[0080] In this embodiment, in order to improve the comprehensiveness of the generated animation, the configuration information may include action information of the target virtual group. Through this action information, the various display actions of the target virtual group are determined, and multiple two-dimensional images that can represent all actions of the target virtual group are effectively extracted to improve the comprehensiveness and accuracy of the generated animation.

[0081] In these embodiments, relative to the first embodiment, step S240 may include the following steps S410 to S440:

[0082] Step S410 : determining the action duration and action sequence of each display action of the target virtual group according to the action information.

[0083] In this embodiment, the target virtual groups are, for example, Zhao Yun and Lu Bu. The action information may include Zhao Yun slashing at Lu Bu, and the displayed actions may include action A1 of Zhao Yun moving toward Lu Bu, action A2 of Zhao Yun slashing at Lu Bu, and action A3 of Lu Bu receiving the attack. Action A1 may last 2 seconds, action A2 may last 1 second, and action A3 may last 0.5 seconds. The order of the actions may be A1-A2-A3.

[0084] Step S420: Determine the action sampling node according to the action duration and action sequence.

[0085] In this embodiment, each display action can be sampled N times, and the sampling interval t is calculated. The specific expression can be: sampling interval t = action duration length / N, where N can be 5, 10, or 15. After the sampling interval for each display action is determined, the action sampling nodes can be determined. For example, if the sampling interval for display action A1 is 0.5, then the action sampling nodes for display action A1 can be: 0s node, 0.5s node, 1s node, 1.5s node, and 2s node.

[0086] Step S430 : extracting a second three-dimensional image of the first three-dimensional image of the target virtual group at the action sampling node.

[0087] Step S440 : determining a second three-dimensional image in a reference direction as a first two-dimensional image of the target virtual group.

[0088] In this embodiment, the first 3D image of the target virtual group can be set to start playback, and a snapshot can be taken every sampling interval t. The snapshot operation can include creating a Render Target map, rendering the 3D skeletal animation to the target virtual group, extracting the texture data of the target virtual group, and encoding it in PNG format to generate a 2D image, namely the first 2D image. The generated first 2D image is then saved as a file with a file name starting with 1.png until the playback of the first 3D image ends. Ultimately, N action sequence frame images, namely the N first 2D images, are obtained.

[0089] <Fourth embodiment>

[0090] In this embodiment, in order to generate animation even when the user's editing operation does not indicate an action for the target virtual group, a default resource file may be obtained, and a display action may be set for the target virtual group using the action information for the target virtual group in the default resource file.

[0091] In these embodiments, compared to the third embodiment, before step S240, the method further includes the following steps S510 and S520:

[0092] Step S510 : when the configuration information of the target virtual group indicated by the editing identifier does not contain the action information of the target virtual group, a set default resource file is obtained.

[0093] In this embodiment, the configuration information of the target virtual group indicated by the editing identifier does not contain the action information of the target virtual group. This can be: the action name in the configuration information of the target virtual group is empty. When the action name is empty, the game engine editor can use "idle" by default or configure the default resource file.

[0094] Step S520: determining the action information for the target virtual group in the default resource file.

[0095] In this embodiment, the action information for the target virtual group in the default resource file may include an action ID of a fixed action, where the fixed action is, for example, a normal attack.

[0096] <Fifth embodiment>

[0097] In this embodiment, in order to reduce the computing resources occupied by generating the first two-dimensional image of the target virtual group, the reference direction can be multiple. By extracting a single two-dimensional image of the first reference direction among the multiple reference directions and using mirror conversion processing, a two-dimensional image of the second reference direction that is a mirror image of the first reference direction can be obtained.

[0098] In these embodiments, compared to the first embodiment, before step S240, the method further includes the following step S610:

[0099] Step S610 : determining, based on the direction values corresponding to the reference directions, whether a first reference direction and a second reference direction in the reference directions have a set association relationship.

[0100] In this embodiment, if Figure 3 As shown, the direction values corresponding to the first reference direction can be 006, 007, and 008, and the direction values corresponding to the second reference direction can be 004, 003, and 002. When the first reference direction is 006, the second reference direction is 004, that is, the first reference direction and the second reference direction have a set association relationship.

[0101] Based on this, step S240 may include the following steps S620 and S630:

[0102] Step S620 : determining a second two-dimensional image of the target virtual group according to the configuration information of the target virtual group indicated by the editing mark, the first reference direction, and the third reference direction among the reference directions.

[0103] In this embodiment, if Figure 3 As shown, the direction values corresponding to the third reference direction may be 001 and 005.

[0104] Step S630 : determining the first two-dimensional images of the target virtual group in the first reference direction, the second reference direction, and the third reference direction according to the second two-dimensional image and the conversion configuration set by the association relationship.

[0105] In this embodiment, the conversion configuration may be a configuration of performing a mirror conversion process on the second two-dimensional image in the first reference direction and converting it into a second two-dimensional image in the second reference direction. The mirror conversion process here is a prior art and will not be elaborated on here.
