Description

Technical Field

[0001] The present disclosure relates to the field of game technology, and in particular to a method, device and electronic device for controlling movement in a game. Background Art

[0002] In the game, in order to simulate the effect of virtual characters moving in scene areas with different surface materials, corresponding triggers (trigger boxes) are generally placed in different areas. When the player controls the virtual character to touch or enter the corresponding area, it will directly affect the player's animation behavior. For example, the character will walk slower in a scene area with a rough surface, or fall more easily in a scene area with a smooth surface. The interactive behavior between the virtual character and the surface of the scene area is regional. Usually, only one parameter can be set in most of each area, resulting in a relatively simple behavior of the virtual character in the scene area. If more detailed interactive behavior is required, the area needs to be divided into smaller triggers. However, setting the trigger area requires manual editing by the level planner. In a more complex environment, dividing a single area into a large number of small trigger points has high labor costs, and the cost of later adjustment and maintenance is high. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0022] In the game, virtual characters will encounter surfaces of various materials, and interactions with objects on different surfaces, such as walking or climbing on them, will require different interactive responses.

[0023] Generally, some trigger boxes are placed in different areas. When the player character (actor) touches or enters the corresponding area, it will directly affect the character's animation behavior, such as walking slower or falling more easily in interactive behaviors. However, this kind of interactive behavior is regional, that is, each area can only set one parameter. If more detailed interactive behavior is required, the area needs to be divided into smaller trigger boxes.

[0024] In the related art, it is usually necessary to manually set different action logic trigger areas in the game level to affect the animation logic of the player character or non-player character (NPC). Or at the beginning of certain special action triggers, it is detected whether the player is equipped with special props and skills, so as to select the corresponding action response. However, setting the trigger area requires manual editing by the level planner. In a more complex environment, a single area may be divided into a large number of small trigger points, which increases the cost of later adjustment and maintenance; special skills and equipment will also affect the behavior logic, and the final character's action logic will become more complicated.

[0025] Based on this, the embodiments of the present disclosure provide a method, device and electronic device for controlling movement in a game, and the technology can be applied to the movement control process of a game character.

[0026] In one embodiment of the present invention, the mobile control method in the game can be run on a local terminal device or a server. When the mobile control method in the game 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.

[0027] 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 mobile control method in the game are completed on the cloud game server. The role of 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 user 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.

[0028] 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 user 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 user in a variety of ways, for example, it may be rendered and displayed on a display screen of the terminal, or provided to the user 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.

[0029] See also Figure 1 First, a method for controlling movement in a game provided by an embodiment of the present invention is introduced. The method comprises the following steps:

[0030] Step S102, in response to the virtual character contacting a scene object in the virtual scene, determining friction-related parameters; wherein the friction-related parameters include at least one of the following: a friction parameter of a first surface portion of the surface of the virtual character that contacts the scene object, a friction parameter of a second surface portion of the surface of the scene object that contacts the virtual character, and a relative motion parameter between the virtual character and the scene object.

[0031] The above virtual character can be a controlled virtual character controlled by a player, or a virtual character controlled by a game system, without limitation. The above virtual character can refer to a virtual character with a certain set attribute in the game, or any character in the game, without limitation.

[0032] The above-mentioned scene object can be an object representing terrain in a virtual scene, such as a "mountain", "plain", etc., or a building object or other object, which is not limited here. The scene object can be fixed in the virtual scene, or can move in the virtual scene according to certain rules. For example, when the scene object represents a Ferris wheel, the scene object needs to rotate around a preset axis.

[0033] When a virtual character contacts a scene object, it is actually part of the surface of the virtual character that contacts part of the surface of the scene object. For the sake of convenience, the surface part of the virtual character that contacts the virtual object is called the "first surface part", and the surface part of the scene object that contacts the virtual character is called the "second surface part". The surface parts of the virtual character that contact the scene object can be multiple, that is, multiple discontinuous surface parts. For example, the hand surface and the foot surface of the virtual character are both in contact with the scene object, and they contact different surface parts of the scene object.

[0034] Friction parameters are usually pre-set for the surfaces of virtual characters and scene objects. Generally speaking, the magnitude of friction is related to the pressure between the contact parts and the roughness of the contact parts. The pressure between the contact parts is usually related to the gravity of the virtual character itself and the relative movement trend between the virtual character and the scene objects. The friction parameters of the first surface part of the virtual character can be used to indicate the gravity of the virtual character that needs to be borne when the first surface part contacts other surfaces, the roughness of the surface part, etc. The friction parameters of the second surface part of the scene object can be used to indicate the roughness of the surface part and the pressure that may be generated when the second surface part contacts other surface parts. It is also possible to set only the friction parameters related to pressure for the virtual character or scene object, or only the friction parameters related to roughness for the virtual character or scene object, for subsequent calculation of friction. There is no limitation here.

[0035] When setting, you can set corresponding friction parameters for the surface parts of the virtual character and scene objects that may come into contact with other surfaces. For example, the feet, hands, back, and buttocks of the virtual character can be set with corresponding friction parameters. Different surface parts can usually be set with different friction parameters to represent the pressure and roughness that may be generated by the surface parts when in contact. For example, a scene object is used to represent a certain terrain. The friction parameter representing the roughness of the sandy part of the terrain is set to a larger value, and the friction parameter representing the roughness of the marble part of the terrain is set to a smaller value.

[0036] Friction will only be generated between the virtual character and the scene object after they have relative motion or a tendency to relative motion. The above relative motion parameters may include one or both of the relative motion direction and the relative motion speed. The relative motion parameters usually need to be determined based on the relative positions of the virtual character and the scene object at different times. Therefore, it is necessary to obtain the relative positions of the two at different times, and then calculate the relative motion speed based on the speed calculation formula, or determine the relative motion direction based on the order in which the relative positions are generated.

[0037] Step S104: determining the friction between the virtual character and the scene object based on the friction-related parameters.

[0038] After determining the friction-related parameters, it is necessary to calculate the friction between the virtual character and the scene object based on the friction-related parameters. In real life, the calculation formula for friction is f=μN, where f represents the magnitude of friction, μ represents the friction coefficient, and N represents the normal pressure. In a virtual scene, the formula can be deformed according to needs. It is worth noting that the normal pressure is required in the calculation formula, and the normal pressure is not exactly the same as the gravity of the virtual character and the pressure of the surface contact of the scene object.

[0039] The friction calculation method can also be set based on demand, for example, setting both the virtual character and the scene object to generate a certain friction, and the friction is established under certain contact conditions. For example, the gravity of the virtual character is the positive pressure that causes friction. In a virtual scene, the direction of the gravity of the surface or the pressure generated can be represented by the normal of the surface. When the gravity of the virtual character is the positive pressure that causes friction, the directions of the normals of the surfaces on which the virtual character and the scene object are in contact are usually opposite. When the directions of the normals of the two are at other angles, it usually causes a change in friction. Specifically, weights can be introduced to calculate the friction between the virtual character and the scene object in the current situation based on the pre-set friction. The above weights are usually calculated based on the angle between the directions of the normals of the two. For example, the cosine value of the normal angle can be taken as the weight.

[0040] In the process of calculating friction, relative motion parameters can also be taken into account. It can be preset that the greater the relative motion speed, the smaller the weight. It can also be set that the greater the angle between the relative motion direction and the two normal directions, the greater the weight, etc. The specific settings can be made according to needs and are not limited here.

[0041] Step S106, determining the moving state of the virtual character based on the friction force, and controlling the virtual character to generate relative motion with the scene object in the moving state.

[0042] The above-mentioned moving state may include sliding, difficult movement or normal movement, etc. Multiple friction thresholds may be set in advance for the virtual character. The friction range determined by two adjacent friction thresholds corresponds to a moving state. For example, when the friction is less than a certain friction threshold, the moving state of the virtual character is determined to be sliding, and the character falls randomly; when the friction is greater than a certain friction threshold, the virtual character is determined to be walking with difficulty. After the moving state of the virtual character is determined, the virtual character may be controlled to generate relative motion with the scene object in the moving state, thereby generating corresponding game behaviors.

[0043] The above-mentioned method for controlling movement in a game determines friction-related parameters in response to the virtual character contacting a scene object in a virtual scene; determines the friction between the virtual character and the scene object based on the friction-related parameters; determines the movement state of the virtual character based on the friction, and controls the virtual character to produce relative movement with the scene object in the movement state. In this method, only different friction parameters need to be set on the surface of the virtual object, so that different virtual objects can produce different frictions when in relative movement, and then set different movement states of the virtual character based on different frictions, which enriches the expression of the movement state of the game character and reduces the labor cost at the same time.

[0044] The following embodiments provide a specific method for determining friction-related parameters in response to a virtual character contacting a scene object in a virtual scene.

[0045] In practical applications, the friction-related parameters may include relative motion parameters between the virtual character and the scene object. The relative motion parameters may include the relative motion direction and may also include the relative motion speed. When determining the relative motion direction, in response to the virtual character contacting the scene object in the virtual scene, it is necessary to determine the initial contact position between the virtual character and the scene object; when the virtual character and the scene object move relative to each other, it is necessary to determine the current contact position between the virtual character and the scene object, and further determine the relative motion direction between the virtual character and the scene object based on the initial contact position and the current contact position. Specifically, the direction from the initial contact position to the current contact position may be determined as the relative motion direction, or the direction from the current contact position to the initial contact position may be determined as the relative motion direction, and there is no limitation here.

[0046] In practical applications, the above-mentioned friction-related parameters may include the friction parameters of the first surface portion of the surface of the virtual character that contacts the scene object. At least one character state may be pre-set for the virtual character. Each character state corresponds to a preset friction parameter, and the friction parameters corresponding to different character states are usually different. For example, the friction parameters corresponding to a character wearing a magic cloak and not wearing a magic cloak are different. When the virtual character contacts the scene object in the virtual scene, the current character state of the virtual character is determined, and then the first friction parameter corresponding to the current character state is determined as the friction parameter of the first surface portion. In the same character state, the friction parameters of different surface portions may be the same or different, and are not limited here.

[0047] In practical applications, the above-mentioned friction-related parameters may include the friction parameters of the second surface portion of the surface of the scene object that is in contact with the virtual character. At least one object state, usually multiple, may be set in advance for the scene object. Each object state corresponds to a preset friction parameter. For example, the friction parameter of the scene object in a dry state is usually greater than the friction parameter of the scene object in a rainy state. When the virtual character contacts the scene object in the virtual scene, it is necessary to determine the current object state of the scene object, and determine the second friction parameter corresponding to the current object state as the friction parameter of the second surface portion. In the same object state, the friction parameters of different surface portions may be the same or different, and are not limited here.

[0048] The following embodiment provides a specific method for determining the friction between a virtual character and a scene object based on friction-related parameters.

[0049] After determining the friction parameters of the first surface portion of the surface of the virtual character that contacts the scene object, the friction parameters of the second surface portion of the surface of the scene object that contacts the virtual character, and the relative motion parameters between the virtual character and the scene object, it is first necessary to determine the initial friction force based on the friction parameters of the first surface portion and the friction parameters of the second surface portion. The initial friction force is usually obtained by adding the friction parameters of the first surface portion and the friction parameters of the second surface portion. Then, based on the initial friction force and the relative motion parameters between the virtual character and the scene object, the friction force between the virtual character and the scene object is determined.

[0050] When the scene object has a roughness parameter, the friction parameter of the second surface portion can be updated based on the roughness parameter corresponding to the second surface portion. When the friction parameters of the surfaces are the same, the corresponding roughness parameters are different, and the friction forces generated are usually different. After the friction parameters are updated, the initial friction force can be determined based on the friction parameters of the first surface portion and the updated friction parameters of the second surface portion.

[0051] The above-mentioned relative motion parameters usually include the relative motion direction. As mentioned above, when the first surface portion has a corresponding first additional mesh model, each vertex on the model has a normal parameter. In a specific implementation, the model portion corresponding to the first surface portion and the surface portion related to the first surface portion can be copied to generate a first additional mesh model. The above-mentioned surface portion related to the first surface portion is usually connected to the first surface portion, and may also be in contact with the scene object, such as the surface portion related to the sole of the foot and the heel. When the copied model portion has a large number of faces, a low-precision model corresponding to the model portion can be generated as the first additional mesh model. The number of faces of the low-precision model is lower than that of the original model, but the shape is similar. The direction of the normal of the vertex of the first additional mesh model can be set according to demand, and the normal direction is usually used to determine the current friction state weight in combination with the normal direction of the scene object.

[0052] Similarly, when the second surface portion has a corresponding second additional mesh model, the vertices on the model have normal parameters. Similar to the first additional mesh model, the second additional mesh model can be generated by copying the model portion corresponding to the second surface portion and the surface portion related to the second surface portion, or the second additional mesh model is a low-precision model corresponding to the model portion of the second surface portion and the surface portion related to the second surface portion.

[0053] The friction state weight can be determined based on the normal parameters of the vertices in the first additional mesh model, the normal parameters of the vertices in the second additional mesh model, and the relative motion parameters between the virtual character and the scene object. Then, the initial friction force is multiplied by the friction state weight to obtain the friction force between the virtual character and the scene object.

[0054] The above-mentioned normal parameters include the normal direction; the relative motion parameters include the relative motion direction. When determining the friction state weight, first determine the vertex closest to the center of the first surface part in the first additional mesh model as the first target vertex, and determine the vertex closest to the center of the second surface part in the second additional mesh model as the second target vertex. Then determine the angle between the first normal direction of the first target vertex and the second normal direction of the second target vertex. Further based on the angle, the relative position between the first normal direction and the relative motion direction, and the relative position between the second normal direction and the relative motion direction, determine the friction state weight. For example, the cosine value of the angle can be calculated first, and then when the first normal direction and the second normal direction are on both sides of the relative motion direction, the multiplication result of the cosine value multiplied by 2 is determined as the friction state weight; when the first normal direction and the second normal direction are on the same side of the relative motion direction, the cosine value is directly used as the friction state weight. It can be set specifically according to needs and is not limited here.

[0055] The disclosed embodiment also provides another method for controlling movement in a game. Figure 1 This method implements the global contact surface friction calculation method of the character, specifically using the value of the object surface normal information and the contact part of the character to calculate the friction.

[0056] While obtaining the normal information of the object surface, you can also overlay the material's modified properties on the normal, such as the bump information of the soil surface, the normal detail information of different areas on the tile, and the roughness information of the material map, to better simulate the performance of friction.

[0057] The hands and feet of the player character (equivalent to the above-mentioned "virtual character") can be set with different friction coefficients respectively (the hand and foot normal information can also be used directly). This makes it easy to set the animation blueprint states in different posture states, such as simple walking state, climbing state using both hands and feet, etc.

[0058] This method introduces the definition and setting of normals on scene object meshes, and can superimpose the normal map and roughness map information on material properties to obtain the final friction coefficient on the object. The corresponding friction coefficient is set at the part where the character contacts the object (equivalent to the above-mentioned "scene object") (hands, feet or the whole body, etc.), so as to calculate the final friction result obtained when the player contacts the scene object, and obtain the corresponding animation action state, such as normal, sliding, falling, etc.

[0059] This method is implemented in the following way:

[0060] 1 Calculate or set the normal direction angle or value information on the scene object mesh.

[0061] 2. Calculate the normal in the object material information and superimpose the corresponding roughness map information weight.

[0062] 3. Set the friction coefficient at the required parts of the character and calculate the friction results after these parts come into contact with the scene objects.

[0063] 4 The animation action state of the player character is achieved through friction.

[0064] Specifically, we first need to calculate the friction parameters of the scene objects. By default, the normal information of the mesh surface of the object is perpendicular to the surface and has the same length.

[0065] This method requires modifying the normal angle to different degrees and adding a strength value to define the friction properties of the object. Figure 2 shown.

[0066] Since normal information is also useful for other links, the changes to normal attributes at this stage will be copied to a new mesh model (also called "mesh", equivalent to the "second additional mesh model" mentioned above), which is used alone to store and calculate all friction-related information. When encountering high poly objects, you can use the object's lod1 mesh for processing.

[0067] Then we need to calculate the effect of the object material on the normal (friction): the normal map in the object material will modify the object surface twice. In the engine editor state, first bake the normal map information onto the friction mesh to obtain the calculated new normal strength and angle information, such as Figure 3 shown.

[0068] At the same time, the roughness of the object material also affects the friction performance of the object surface. Since the roughness map is just a black and white weight range map, it will only affect the strength value of the normal. Figure 4 shown.

[0069] In the roughness map, the value 0 (black) represents a smooth area, and the value 1 (white) represents a rough area. Since a fully reflective surface does not mean no friction in the real world, the roughness [0,1] interval needs to be mapped to the [1,2] interval in the actual processing process. The friction value obtained in the previous step can be multiplied by the roughness weight value. In the end, a slightly rough metal surface should be presented in the game.

[0070] It is also necessary to set the friction properties of the character's contact parts according to the game requirements, such as setting the friction mesh of the hand or foot contact parts (equivalent to the above-mentioned "first additional mesh model"), such as Figure 5 shown.

[0071] You can set up several sets of friction mesh according to different situations, such as using a smaller mesh in the rain, increasing friction after wearing special gloves, etc.

[0072] Furthermore, it is necessary to calculate the friction between the scene mesh object and the player character. In practical applications, the friction when the normal direction of the scene object and the character contact part is completely opposite (180°) can be defined as the standard friction, without any weight addition. When the character contact part moves, the position from the initial point of the movement to the current state is the positive quadrant, and the other interval is the negative quadrant, such as Figure 6 As shown in the figure, the character's feet enter from point O on the right side of the screen and move to point P on the left side of the screen. The left side is set to be the negative direction of the normal, and a coordinate system is established with point P. The right side is the positive quadrant and the left side is the negative quadrant.

[0073] Calculate the normal angle of the mesh vertex closest to the vertex of the object that the character is touching. If the two normal angles are in the positive quadrant, that is, the angle is less than 90 degrees, the friction weight is in the interval [1,2]. When the normal angle is 90°, the weight is 2, and when the normal angle is 180°, the weight is 1. If the two normal angles are in the negative quadrant, the friction weight interval is [0,1]. When the angle is 90°, the weight is 0, and when the normal angle is 180°, the weight is 1. Figure 6 As shown, α represents an angle less than 90 degrees, and β represents an angle greater than 90 degrees.

[0074] So the final friction value calculation formula is:

[0075] Friction = (character contact object friction + object friction * roughness weight) * friction state weight

[0076] Game action planners can customize the friction definition interval. For example, if the friction is less than a certain threshold, the sliding action will be used, and if it is less than a certain extreme value, the character will fall.

[0077] This method has the following advantages:

[0078] 1. Convenience: Since objects naturally have different normal information, they can naturally provide basic friction parameters. After superimposing the information on the material, the friction properties of the object can be more accurately represented, and the friction properties can also be manually modified. There is no need to set the trigger range separately for different areas and objects.

[0079] 2. Efficiency: The friction properties of objects can be baked and recorded in the editor stage of the engine, and the result values ​​can be directly calculated in the runtime stage to avoid performance waste caused by multiple calculations.

[0080] 3 Universality: The calculation method provided by this method can be used in different game engines and DCC animation special effects production software.

[0081] For the above method embodiments, see Figure 7 A mobile control device in a game is shown.

[0082] The device includes:

[0083] The friction-related parameter determination module 702 is used to determine the friction-related parameters in response to the virtual character contacting the scene object in the virtual scene; wherein the friction-related parameters include at least one of the following: a friction parameter of a first surface portion of the surface of the virtual character contacting the scene object, a friction parameter of a second surface portion of the surface of the scene object contacting the virtual character, and a relative motion parameter between the virtual character and the scene object;

[0084] The friction force determination module 704 is used to determine the friction force between the virtual character and the scene object based on the friction related parameters;

[0085] The movement control module 706 is used to determine the movement state of the virtual character based on the friction force, and control the virtual character to generate relative motion with the scene object in the movement state.
