Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0055] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0056] Generally, game storylines and cutscenes are created using the Unity engine, most often employing the engine's built-in Timeline tool. However, the Timeline workflow can only create storylines with fixed characters, and those characters can only perform fixed animation clips. In the game, players can choose different characters to represent themselves, so the performers may be different actors, each using different animation clips. The choice of which actor to use cannot be determined during storyline creation; the actor selection can only be decided during gameplay, and the same applies to the matching animation clips.

[0057] Existing solutions either create different storylines for different actor combinations or create a separate storyline for each actor and combine them. However, creating different storylines for different actor combinations requires exhaustively listing all possible actor combinations and creating storylines with identical content for each. The game then selects which storyline to use based on the actor combination during runtime. Conversely, creating a separate storyline for each actor and combining them requires dividing the storyline into different parts based on the actor, creating each actor's part independently. During playback, all actors' storylines play simultaneously, combining to form a unified storyline.

[0058] However, the possibilities for actor combinations increase exponentially with the variety of roles, making this method extremely labor-intensive. Separate production is also inconvenient and requires a significant amount of work. If the actors have significant size differences and interact (such as in fight scenes), the possibility of continuity errors is relatively high.

[0059] Based on the above, this specification provides a method, apparatus, electronic device, and storage medium for applying game storylines, which can effectively alleviate the aforementioned technical problems.

[0060] Please refer to Figure 1This is a block diagram of an electronic device 100 provided in this application. The electronic device 100 can be a device capable of performing various game story animations; this embodiment does not limit this. The electronic device 100 includes a memory 110, a processor 120, and a communication module 130. The memory 110, processor 120, and communication module 130 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0061] The memory 110 is used to store programs or data. The memory 110 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.

[0062] The processor 120 is used to read / write data or programs stored in memory and to perform corresponding functions.

[0063] The communication module 130 is used to establish a communication connection between the server and other communication terminals through the network, and to send and receive data through the network.

[0064] It should be understood that, Figure 1 The structure shown is only a schematic diagram of the electronic device 100. The electronic device 100 may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof. The electronic device 100 can be integrated into a computer or configured as a stand-alone device.

[0065] Correspondingly, embodiments of the present invention provide a method for applying game storylines, which can be applied to electronic device 100. The method includes, for example,... Figure 2 The following steps are shown:

[0066] Step S110: Create multiple target actors of different types.

[0067] Step S120: Bind the target actor to the target story file, the target story file including multiple animation instruction fragments.

[0068] Step S130: Based on the animation clip lookup table, determine multiple animation clips according to the target actor and the animation instruction fragment, wherein each target actor and each animation instruction fragment corresponds to one animation clip.

[0069] Step S140: Play the animated segments according to the preset plot sequence.

[0070] Before applying a game storyline, a target storyline file needs to be created for the game storyline to be applied. As an optional implementation, the method further includes the step of creating the target storyline file, which includes, for example... Figure 3 The following sub-steps are shown:

[0071] Sub-step S210: Obtain multiple story actors and multiple animation instructions that the story actors can execute.

[0072] Sub-step S220: Create the animation segment based on the story actor and the animation instruction, wherein one story actor and one animation instruction determine a unique animation segment.

[0073] Sub-step S230: Based on the preset script, create a target storyline according to the storyline actors and the animation clips.

[0074] Sub-step S240: Create the target plot file based on the target plot.

[0075] The target story file can be a story file used in subsequent game playback. Story actors can be the actors needed to create the target story file; for example, if the target story file requires "male actors running," then the story actors can be "any male actor." Animation instructions can be commands that all story actors can execute, such as running, jumping, reading, etc.

[0076] First, acquire multiple story actors and multiple animation commands. Each animation command is executable by each story actor, and each story actor and each animation command can determine a unique animation clip. After determining multiple animation clips, these clips can be created using other tools. It should be noted that these animation clips, determined by story actors and animation commands, are the animation clips needed for subsequent application to the game's storyline.

[0077] A pre-set script can be a plan for the game's plot to be played later. For example, it specifies which character will execute which animation command and which animation segment from a certain point in time. Based on the pre-set script, it determines when each character will execute which animation commands and which corresponding animation segments, and then creates the target plot, further creating the target plot file.

[0078] Optionally, the step of creating a target plot based on a preset script, according to the script actors and the animated segments, includes:

[0079] Multiple story tracks are created according to the preset script, and each story track corresponds to at most one story actor and multiple animation segments corresponding to the story actor.

[0080] According to the preset plot sequence, corresponding animation segments are set on each of the plot tracks.

[0081] Create the target storyline based on the pre-set storylines.

[0082] Each preset script includes animation segments executed simultaneously by multiple actors, as well as camera animation. Multiple story tracks can be created from the preset scripts. Some story tracks correspond to story actors, while others do not. Story tracks with actors correspond to animation segments defined by the animation instructions to be executed by that actor.

[0083] The preset storyline order can be the chronological order in which the various animation segments play. After determining each storyline track and its corresponding actors and animation segments, the animation segments are placed on their respective storyline tracks according to the preset storyline order. The combination of these storyline tracks creates the target storyline.

[0084] like Figure 4 As shown, this is a complete target storyline, including three storylines: A, B, and C. Storyline A corresponds to actor A, storyline B corresponds to actor B, and storyline C has no corresponding actor. According to the preset script, animation clips 1, 2, and 3 are sequentially set on storyline A, animation clips 4 and 5 are set on storyline B, and camera animation is set on storyline C. When the target storyline is played, each storyline track plays different animation clips / camera animations according to the timeline, thus forming the complete target storyline.

[0085] Optionally, each animation instruction corresponds to one animation instruction fragment, and the step of creating the target plot file based on the target plot includes:

[0086] Based on the animation instruction lookup table, the animation instructions corresponding to each animation segment are determined according to the plot actors and animation segments corresponding to each plot track.

[0087] Based on each of the determined animation instructions, each of the animation segments is replaced with the corresponding animation instruction fragment.

[0088] Remove the binding between the aforementioned character and the aforementioned plot track.

[0089] Based on the target storyline corresponding to the storyline track that has been unbound from the aforementioned storyline actors and whose animation segments have been replaced, the target storyline file is created.

[0090] An animation instruction lookup table can be created based on the mapping relationship between story actors, animation clips, and animation instructions. A unique animation instruction can be found for each unique story actor and animation clip. Based on this lookup table, the animation instruction corresponding to each animation clip on a story track with a corresponding story actor can be found. After determining all the animation instructions, each animation clip is replaced with the animation instruction fragment corresponding to its determined animation instruction. Then, the mapping relationship between story actors and story tracks is broken. Finally, by unbinding the story actors and replacing the animation clips on the corresponding story tracks, the target story file is created.

[0091] For example, story track X corresponds to story actor Y. This story track contains two animation clips: story actor Y eating watermelon and story actor Y washing hands. Based on story actor Y and the two animation clips (story actor Y eating watermelon and story actor Y washing hands), two animation instructions can be determined: eating watermelon and washing hands. These instructions are then replaced with their corresponding animation instruction clips and saved on story track X. The binding relationship between story actor Y and story track X is then removed, and the target story file is created based on this current story track X.

[0092] It should be noted that since some story tracks have story actors bound to them while others do not, in order to avoid the absence of target actors on story tracks during subsequent playback, the binding relationship between story actors and story tracks can be recorded and generated into an asset file. When applying the game storyline later, the target actors can be bound to the corresponding story tracks according to the binding relationship in the asset file.

[0093] After creating the target story file, proceed to step S110 to create multiple target actors of different types.

[0094] Target actors are actors created based on the game's runtime environment and are currently needed. Target actors can be any type of character, and their number is less than or equal to the number of story actors.

[0095] Step S120 is executed to bind the target actor to the target story file, which includes multiple animation instruction fragments.

[0096] After creating the target actor, you need to bind the target actor to the target story file that was created earlier.

[0097] Optionally, binding the target actor to the target plot file includes: binding each target actor to a different plot track according to the preset script.

[0098] Since it's a reuse of a game's storyline, the default script is the same when creating the target storyline file and during subsequent reuse; only the actors differ. The target actors are bound to the target storyline file, which can be done based on the default script and an asset file that records the binding relationships, placing the target actors on different storylines. Storylines without binding relationships are left unprocessed.

[0099] Step S130 is executed, based on the animation clip lookup table, multiple animation clips are determined according to the target actor and the animation instruction fragment, wherein each target actor and each animation instruction fragment corresponds to one animation clip.

[0100] An animation clip lookup table can be created based on the mapping relationship between target actors, animation instruction fragments, and animation clips. A unique animation clip can be found based on a unique target actor and animation instruction fragment.

[0101] Optionally, determining multiple animation segments based on the animation segment lookup table, according to the target actor and the animation instruction fragment, includes: determining the animation segment on each plot track based on the target actor bound to each plot track and the animation instruction fragment on that plot track.

[0102] After binding each target actor to its corresponding storyline, the corresponding animation clips on each storyline can be found based on the animation clip lookup table, according to the target actor and each animation instruction clip.

[0103] Execute step S140, and play each of the animated segments in the preset plot order.

[0104] After the target actors are bound together and the animation segments on each plot track are determined, the corresponding animation segments of each target actor are played according to the preset plot order to complete the application of the game plot.

[0105] Optionally, playing the animated segments according to a preset plot sequence includes:

[0106] The animation segments on each of the story tracks are arranged on the timeline according to the preset storyline order.

[0107] When the target storyline reaches a position on the timeline where the animated segment exists, one or more of the animated segments corresponding to that position are played.

[0108] Still with Figure 4 For example, when playing various animation segments, first arrange the animation segments / camera animations on each story track on the timeline, and play the target story from the beginning position. When the playback reaches a position on the timeline where a certain animation segment is located (e.g., Figure 4 At 00:12 (position), story tracks A, B, and C will simultaneously begin playing their corresponding animation clips / camera animations.

[0109] Optionally, the method further includes the step of creating the animation clip lookup table and the animation instruction lookup table, which includes:

[0110] Create an animation clip lookup table using the target actor and the animation instruction fragment as keys and the animation clip as values.

[0111] Create an animation instruction lookup table using the aforementioned actors and animation clips as keys and the aforementioned animation instructions as values.

[0112] To facilitate searching for animation clips and animation commands, an animation clip lookup table can be created, using the target actor and animation command clip as keys and the animation clip as values; an animation command lookup table can be created, using the plot actor and animation clip as keys and the animation command as values. These tables can then be stored in a command mapping library. When a search for animation clips and animation commands is needed, the animation clip lookup table and the animation command lookup table can be retrieved from the command mapping library.

[0113] Based on the same inventive concept, such as Figure 5 As shown in the embodiment of this invention, a game plot application device 300 is provided. The game plot application device 300 includes:

[0114] Target actor creation unit 301 is used to create multiple target actors of different types.

[0115] The target actor binding unit 302 is used to bind the target actor to a target plot file, the target plot file including multiple animation instruction fragments.

[0116] Animation segment determination unit 303 is used to determine multiple animation segments based on the animation segment lookup table, according to the target actor and the animation instruction fragment, wherein each target actor and each animation instruction fragment corresponds to one animation segment;

[0117] The animation clip playback unit 304 is used to play each of the animation clips in a preset plot order.

[0118] Regarding the game plot application device 300 mentioned above, the specific functions of each unit have been described in detail in the embodiments of the game plot application method provided in this specification, and will not be elaborated here.

[0119] Based on the same inventive concept, embodiments of this invention provide a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of any of the methods in the aforementioned game plot application method.

[0120] The present invention has at least the following beneficial effects:

[0121] By creating multiple target actors of different types, when animation / storyline needs to be played, the target actor is applied to a pre-created target storyline file. Then, according to the animation clip lookup table, the corresponding animation clip for each target actor is found, and the animation clips are played in the preset storyline order. This allows different actors to use the same target storyline file, achieving the technical effect of "one-time production, universal application." This reduces workload and improves the efficiency of storyline production.
