Such skills or capabilities may be activated by a player of the game using one of a plurality of preset touch operations with a touch display screen of the terminal. The processor may be configured to present a corresponding game screen in response to an operation instruction generated by a touch operation of a user.

The following detailed description is given with reference to specific examples.

Please refer to fig. 2, which is a flowchart illustrating a method for switching states of a virtual role according to an embodiment of the present disclosure. The method for switching the state of the virtual role provided by the embodiment of the application is applied to the electronic equipment, and the specific flow of the method can be as follows:

step 101, responding to a state switching instruction aiming at the virtual character, and acquiring the current bone position of the virtual character from the currently played original state animation.

In this embodiment, the electronic device provides a graphical user interface, the graphical user interface includes a game scene, and the virtual character is located in the game scene. The game scene is a virtual environment provided by the game running on the electronic device, and the virtual environment can be a simulation environment of a real world, a semi-simulation semi-fictional three-dimensional environment or a pure fictional three-dimensional environment. The virtual character refers to a character which is active in a game scene, such as a virtual character and the like.

The virtual character may have multiple states in the game scene, such as traveling (including walking, running), turning, stopping, jumping, squatting, lying down, standing, and the like. The states can be switched, for example, the virtual character can be switched from squatting to standing, or from standing to squatting. Each state corresponds to a state animation, the electronic equipment plays the state animation on the graphical user interface to realize the state display of the virtual character, and the state switching of the virtual character is realized through the switching of the state animation.

The state-switch instruction may be triggered in a number of ways. For example, the virtual character may be controlled by a game player who operates the virtual character on the electronic device to change the state of the virtual character, thereby triggering generation of a state switching instruction. For another example, a change in the environment in which the virtual character is located in the game scene causes the virtual character state to need to change, thereby triggering generation of the state switching instruction.

The electronic device needs to switch the virtual character from one state to another state according to the state switching instruction. The state of the virtual role before switching is an original state, the state of the virtual role after switching is a target state, and the original state and the target state are different states. The state switching instruction comprises a state identifier, and the electronic equipment can determine a target state corresponding to the state identifier in response to the state switching instruction. For example, the state identifier in the state switching instruction is a step-down identifier, and the electronic device may determine that the target state is step-down in response to the state switching instruction.

The animation corresponding to the original state is the original state animation, and the electronic equipment plays the original state animation before the state of the virtual character is switched. The raw state animation includes a plurality of consecutive acyclic animation frames. And if the original state comprises repeated loop actions, taking the animation corresponding to a set of loop actions as the original state animation. For example, when the original state is the travel state, an animation corresponding to the virtual character in one cycle of the step circulation motion (i.e., right foot landing, left foot raising → right foot raising, left foot landing → right foot landing, left foot raising, or left foot landing, right foot raising → left foot raising, right foot landing → left foot lowering, right foot raising) is taken as the travel animation.

The original state of the virtual character can be shown by circularly playing the original state animation. That is, the first frame of the original state animation continues to be played after the last frame of the original state animation is played until the state of the virtual character changes. It should be noted that the action of the virtual character in the last frame of the original state animation is consistent or continuous with the action in the first frame, so as to ensure that the display effect of the original state of the virtual character is natural and real.

In the process of playing the original state animation, responding to a state switching instruction aiming at the virtual character, and acquiring the bone position (namely the current bone position) of the virtual character in the original state animation at the current time point. The bone position of the virtual character may be the position of a particular bone of the virtual character, the bone position changing in real-time in the raw state animation. When the origin state is travel, that is, the origin state animation is a travel animation, the bone position of the virtual character may be a foot bone position (including a left foot bone position and/or a right foot bone position), and the foot bone position may be a distance between the foot bone and the ground, including a distance between the left foot bone and the ground and/or a distance between the right foot bone and the ground. .

In one embodiment, an animation frame (current animation frame) corresponding to a current time point in the original state animation is obtained, and the bone position (i.e. the current bone position) of the virtual character in the current animation frame is determined.

In another embodiment, the raw state animation curve is pre-established to determine the current bone position from the raw state animation curve. Specifically, the obtaining the current bone position of the virtual character from the currently played original state animation in step 101 includes: and acquiring the current bone position from a pre-established original state animation curve according to the current time point of the original state animation, wherein the original state animation curve is a relation curve of the bone position and the time point of the virtual character in the original state animation.

When the original state animation curve is established, the bone position in each animation frame of the original state animation can be determined, then the time point of each animation frame (the time point of playing the animation frame in the original state animation) corresponds to the bone position, and all the bone positions are connected into the original state animation curve according to the sequence of the time points. Or, a plurality of key animation frames can be selected from the original state animation, the bone positions in the key animation frames are determined, the time point of each key animation frame corresponds to the bone position, and the connecting line between two adjacent bone positions at the time point is smoothed to obtain an original state animation curve.

When the original state animation curve is established, the original state animation curve can be directly generated according to the corresponding relation between the bone positions and the time points, or the bone positions can be converted into uniform curve values, and the original state animation curve can be generated according to the corresponding relation between the curve values and the time points.

For example, the original state animation is a running animation (e.g., a running animation) corresponding to the virtual character during a round of foot circulation (e.g., right foot landing, left foot lifting → right foot lifting, left foot landing → right foot landing, and left foot lifting) of the virtual character, and the bone position of the virtual character is a foot bone position (e.g., a left foot bone position). As shown in fig. 3, key animation frames are selected from the moving animation, and include a first animation frame (where the right foot lands and the left foot is farthest from the ground) 11, a second animation frame (where the left foot lands and the right foot is farthest from the ground) 12, and a third animation frame (where the right foot lands and the left foot is farthest from the ground) 13. Then, the left foot bone position in the first animation frame 11, the second animation frame 12, and the third animation frame 13 is acquired, and the left foot bone position is converted into a curve value between 0 and 1 such that the curve value when the left foot bone is farthest from the ground is 1 and the curve value when the left foot bone completely contacts the ground is 0. Then, the curve value is associated with the time point, and the connection line between two adjacent left foot bone positions at the time point is smoothed, so as to obtain a traveling animation curve corresponding to the left foot bone, that is, the curve is the corresponding relation curve of the left foot bone position L and the time point t in the traveling animation, as shown in fig. 4. Similarly, the method can also obtain a curve of the moving animation corresponding to the right foot bone, that is, the curve is a corresponding relation curve of the right foot bone position R and the time point t in the moving animation, as shown in fig. 4.

After the original state animation curve is established, responding to a state switching instruction, acquiring a current time point, namely a time point played by the current original state animation, and acquiring a skeleton position corresponding to the current time point from the original state animation curve, wherein the skeleton position is the current skeleton position of the virtual character in the original state animation. As shown in fig. 4, the original state animation curve is a traveling animation curve (including a traveling animation curve corresponding to a left bone and a traveling animation curve corresponding to a right bone), when a state switching instruction is responded, the acquired current time point is t1, the left bone position corresponding to the current time point t1 can be obtained from the traveling animation curve corresponding to the left bone as L1, and the right bone position corresponding to the current time point t1 can be obtained from the traveling animation curve corresponding to the right bone as R1.

It should be noted that the animation curve in the original state needs to be a smooth curve to avoid errors in matching of animation frames during switching of subsequent states, thereby ensuring matching effect.

In the embodiment, the original state animation curve is pre-established, so that when the virtual character needs to be switched over, the current bone position of the virtual character is directly obtained from the pre-established original state animation curve, the bone position in the original state animation does not need to be calculated in real time, and the data calculation amount is effectively reduced.

Step 102, according to the current bone position, determining a playing start frame from a switching animation, wherein the switching animation comprises a target state animation and a transition animation spliced before the target state animation, the transition animation comprises at least part of the original state animation, and the playing start frame is an animation frame in the transition animation.

In this embodiment, the state of the virtual character after switching is the target state, that is, the virtual character can be switched from the original state to the target state, and the animation corresponding to the target state is the target state animation. For example, the original state animation includes a travel animation, and the target state animation includes a turn animation, a stop animation, a jump animation, a crouch animation, or the like. The switch animation may include a transition animation and a target state animation, with the transition animation stitched before the target state animation. The transition animation is used for transition between the original state animation and the target state animation, and the problems of sudden change of motion, blockage and the like when the virtual character is switched from the original state to the target state are avoided.

The transition animation includes at least a portion of the raw state animation, i.e., the transition animation may be a complete raw state animation or may be an animation segment of the raw state animation (i.e., a portion of the raw state animation).

When the transition animation is complete original state animation, the target state may be correspondingly set with a switching animation, that is, the original state animation is spliced before the target state animation to be used as the switching animation. Because the transition animation comprises all animation frames of the animation in the original state, namely the transition animation comprises all actions of the virtual character in the original state, whenever a state switching instruction is triggered, the animation frame (namely the playing start frame) matched with the current animation frame of the animation in the original state can be found from the transition animation, so that the playing start frame is consistent or continuous with the actions of the virtual character in the current animation frame of the animation in the original state.

In order to avoid the overlong duration of the transition animation and ensure that the states of the virtual character can be switched in time, the original state animation can be split into a plurality of animation segments, each animation segment forms a candidate transition animation which is spliced before the target state animation, and a candidate switching animation is formed. That is, different candidate transition animations may be spliced before the target state animation to form different candidate switching animations, so that the target state may set a plurality of candidate switching animations correspondingly, so as to select one candidate switching animation from the plurality of candidate switching animations as the final switching animation.

Specifically, the determining a playing start frame from the switching animation according to the current bone position in step 102 includes: determining the switching animation from a plurality of preset candidate switching animations according to the current bone position, wherein the candidate switching animation comprises candidate transition animations, and the candidate transition animations in the candidate switching animations form the complete original state animation; and determining the playing starting frame from the switching animation according to the current bone position.

The candidate switching animation comprises a target state animation and a candidate transition animation spliced before the target state animation, wherein the candidate transition animation is an animation segment of the original state animation. The candidate transition animations (namely the candidate transition animations in the candidate switching animations) are not overlapped, and the candidate transition animations form a complete original state animation, so that the candidate transition animations comprise all actions of the virtual character in the original state, and whenever a state switching instruction is triggered, an animation frame (namely a play start frame) matched with a current animation frame of the original state animation can be found from one candidate transition animation, so that the play start frame is consistent with or continuous with the actions of the virtual character in the current animation frame of the original state animation.

In one embodiment, a plurality of candidate transition animations may be set according to the bone position of the virtual character in the raw state animation to ensure that the bone positions of the virtual character in the plurality of candidate transition animations are different. After the current bone position of the virtual character in the original state animation is obtained, candidate transition animations matched with the current bone position are found from the candidate transition animations, the candidate transition animations are used as transition animations, and the candidate switching animations to which the candidate transition animations belong are used as switching animations.

Specifically, a candidate switching animation curve is established for each candidate switching animation in advance, and the candidate switching animation curve is a corresponding relation curve of the bone position and the time point of the virtual character in the candidate switching animation. The candidate switching animation curves comprise candidate transition animation curves, and the candidate transition animation curves are corresponding relation curves of the bone positions and time points of the virtual characters in the candidate transition animation. After the current bone position of the virtual character in the original state animation is obtained, a candidate transition animation curve with the current bone position is found from the multiple candidate transition animation curves, the candidate transition animation corresponding to the candidate transition animation curve is used as the transition animation, and the candidate switching animation corresponding to the candidate transition animation curve is used as the switching animation.

In another embodiment, a plurality of candidate transition animations can be set according to the bone position change trend of the virtual character in the original state animation, so as to ensure that the bone position change trends of the virtual character in the plurality of candidate transition animations are different. For example, the original state animation is a running animation, the running animation is split into two animation segments, and two candidate transition animations are correspondingly set according to the two animation segments, namely a first candidate transition animation (such as right foot landing, left foot lifting → right foot lifting, and left foot landing) and a second candidate transition animation (such as right foot lifting, left foot landing → right foot landing, and left foot lifting). When the bone positions include a left foot bone position, the left foot bone position change trend of the first candidate transition animation is downward, and the left foot bone position change trend of the second candidate transition animation is upward. When the bone positions comprise a right foot bone position, the change trend of the right foot bone position of the first candidate transition animation is ascending, and the change trend of the right foot bone position of the second candidate transition animation is descending.

After the current bone position of the virtual character in the original state animation is obtained, the current bone position change trend of the virtual character is determined, candidate transition animations matched with the bone position change trend are determined from a plurality of candidate transition animations, the candidate transition animations are used as transition animations, and the candidate switching animations to which the candidate transition animations belong are used as switching animations.

Specifically, the determining the switching animation from a plurality of preset candidate switching animations according to the current bone position includes: acquiring a previous bone position of the virtual character from the original state animation, wherein the previous bone position is a bone position corresponding to a previous time point of a current time point; determining the current bone position change trend of the virtual character according to the current bone position and the previous bone position; and determining the switching animation from a plurality of preset candidate switching animations according to the bone position change trend.

The previous bone position can be determined directly from the animation frame. Specifically, an animation frame corresponding to a time point before a current time point in the original state animation is obtained, that is, an animation frame before the current animation frame in the original state animation is obtained, and then a bone position (that is, a previous bone position) of the virtual character in the previous animation frame is determined.

The previous bone position may also be obtained by a pre-established raw state animation curve. Specifically, a time point before the current time point is determined from the original-state animation curve, each time point may correspond to an animation frame, and the previous time point may be a time point corresponding to a previous animation frame of the current animation frame. Then, the bone position corresponding to the previous time point (i.e. the previous bone position) is obtained from the original state animation curve. As shown in fig. 4, the original state animation curve is a travel animation curve (including a travel animation curve corresponding to a left bone and a travel animation curve corresponding to a right bone), a previous time point at a current time point t1 is t0, a position of the left bone corresponding to the previous time point t0 is L0, and a position of the right bone corresponding to the previous time point t0 is R0.

And comparing the previous bone position with the current bone position to determine the current bone position change trend of the virtual character in the original state animation. If the current skeleton position is larger than the previous skeleton position, determining that the current skeleton position change trend of the virtual character in the original state animation is rising; and if the current bone position is smaller than the previous bone position, determining that the current bone position change trend of the virtual character in the original state animation is descending.

For example, the bone positions include a left foot bone position and a right foot bone position, and a left foot bone position variation trend and a right foot bone position variation trend may be determined, respectively. As shown in fig. 4, the left foot bone position L1 corresponding to the current time point t1 is smaller than the left foot bone position L0 corresponding to the previous time point t0, and the left foot bone position change trend is a decrease. The right foot bone position L1 corresponding to the current time point t1 is smaller than the right foot bone position L0 corresponding to the previous time point t0, and the change trend of the right foot bone position is rising.

Because the bone position change trends of the virtual character in the candidate transition animations are different, according to the current bone position change trend of the virtual character in the original state animation, a matched candidate transition animation can be found from the candidate transition animations, the candidate transition animation is used as the transition animation, and the candidate switching animation to which the candidate transition animation belongs is used as the switching animation.

Specifically, the determining the switching animation from a plurality of preset candidate switching animations according to the bone position change trend comprises the following steps: determining candidate transition animation curves with curve trends consistent with the bone position change trend from a plurality of pre-established candidate transition animation curves as transition animation curves, wherein the curve trends of the candidate transition animation curves are different, and the candidate transition animation curves are relation curves of the bone positions and time points of the virtual characters in the candidate transition animation; and taking the candidate transition animation corresponding to the transition animation curve as the transition animation, and taking the candidate switching animation to which the transition animation belongs as the switching animation.

And establishing a candidate switching animation curve for each candidate switching animation in advance, wherein the candidate switching animation curve is a corresponding relation curve of the bone position and the time point of the virtual character in the candidate switching animation, and the establishing mode of the candidate switching animation curve is the same as that of the original state animation curve, and the details are not repeated here. The candidate switching animation curves comprise candidate transition animation curves. Due to the fact that the skeleton position change trends in different candidate transition animations are different, curve trends of different candidate transition animation curves are different. And taking the candidate transition animation curve with the curve trend consistent with the current bone position change trend of the virtual character in the original state animation as the transition animation curve.

For example, the origin state animation is a travel animation, the target state animation is a stop animation, and the bone positions of the virtual character are foot bone positions (including a left foot bone position and/or a right foot bone position). Setting a first candidate transition animation (such as right foot landing, left foot lifting → right foot lifting, left foot landing) and a second candidate transition animation (such as right foot lifting, left foot landing → right foot landing, left foot lifting) according to the travel animation. And respectively splicing the first candidate transition animation and the second candidate transition animation before the stop animation to obtain a first candidate switching animation and a second candidate switching animation. As shown in fig. 5, the first candidate switching animation includes a plurality of animation frames, such as a first animation frame (right foot landing, left foot lifting) 21, a second animation frame (right foot lifting, left foot landing) 22, and a third animation frame (right foot landing, left foot landing) 23. Wherein animation frames between the first animation frame 21 and the second animation frame 22 form a first candidate transition animation, and animation frames between the second animation frame 22 and the third animation frame 23 form a stop animation. As shown in fig. 6, the second candidate switching animation includes a plurality of animation frames, such as a first animation frame (left foot landing, right foot lifting) 31, a second animation frame (left foot lifting, right foot landing) 32, and a third animation frame (left foot landing, right foot landing) 33. Wherein animation frames between the first animation frame 31 and the second animation frame 32 constitute a second candidate transition animation, and animation frames between the second animation frame 32 and the third animation frame 33 constitute a stop animation.

It should be noted that, in order to ensure that the target state animation and different candidate transition animations are linked naturally and smoothly, the target state animations in different candidate transition animations may be different but all appear in the same state. For example, the stop animation in the first candidate switching animation in fig. 5 is landed on the left foot first and then landed on the right foot, and the stop animation in the second candidate switching animation in fig. 6 is landed on the right foot first and then landed on the left foot, but both states are stopped.

And respectively establishing a first candidate switching animation curve and a second candidate switching animation curve. As shown in fig. 7, the first candidate switching animation curve may include a first candidate switching animation curve corresponding to a left foot bone (a correspondence curve of a left foot bone position L with a time point t) and a first candidate switching animation curve corresponding to a right foot bone (a correspondence curve of a right foot bone position R with a time point t). The curve corresponding to the time points t2 to t3 in the first candidate switching animation curve is a first candidate transition animation curve, and the curve corresponding to the time points t3 to t4 is a step-stopping animation curve. As can be seen from fig. 7, the curve trend of the first candidate transition animation curve corresponding to the left foot bone is downward, and the curve trend of the first candidate transition animation curve corresponding to the right foot bone is upward. As shown in fig. 8, the second candidate switching animation curves may include a second candidate switching animation curve corresponding to a left foot bone (a correspondence curve of a left foot bone position L with a time point t) and a second candidate switching animation curve corresponding to a right foot bone (a correspondence curve of a right foot bone position R with a time point t). The curve corresponding to the time point t5 to t6 in the second candidate switching animation curve is a second candidate transition animation curve, and the curve corresponding to the time point t6 to t7 is a step-stopping animation curve. As can be seen from fig. 8, the curve trend of the second candidate transition animation curve corresponding to the left foot bone is rising, and the curve trend of the second candidate transition animation curve corresponding to the right foot bone is falling.

And if the current change trend of the left foot bone position of the virtual character in the moving animation is descending and the current change trend of the right foot bone position in the moving animation is ascending, matching the change trend with the curve trend of the first candidate transition animation curve, determining the first candidate transition animation curve as the transition animation curve, taking the candidate transition animation corresponding to the first candidate transition animation curve as the transition animation, and taking the candidate switching animation corresponding to the first candidate transition animation curve as the switching animation.

It should be noted that, if the bone position in the candidate transition animation curve and the bone position in the original state animation curve are the same bone position, for example, the original state animation curve is a correspondence curve of the left foot bone position and the time point, the candidate transition animation curve is also a correspondence curve of the left foot bone position and the time point.

In the embodiment, the animation segments of the animation in the original state are used as the transition animation for switching the animation, so that the smooth movement of the virtual character is ensured, the overlong duration of the transition animation is avoided, the sensitivity of state switching response is improved, and the state of the virtual character can be timely switched. In addition, the setting of the transition animation can improve the sense of reality of state switching, for example, when the virtual character is switched from moving to stopping, the virtual character needs to move forward again due to inertia to stop.

After the switching animation is determined, the playing starting animation frame can be determined from the transition animation of the switching animation. Specifically, the determining a play start frame from the switching animation according to the current bone position includes: acquiring a target time point corresponding to the current bone position from a pre-established transition animation curve, wherein the transition animation curve is a relation curve of the bone position and the time point of the virtual character in the transition animation; and determining a target animation frame corresponding to the target time point from the transition animation, and taking the target animation frame as the playing start frame.

Since the transition animation includes at least a portion of the original state animation, and the transition animation is selected based on the current bone position of the virtual character in the original state animation, the transition animation curve has the current bone position. And acquiring a time point corresponding to the current bone position from the transitional animation curve as a target time point, wherein the target time point is different from the current time point corresponding to the current bone position in the original state animation curve. The target animation frame corresponding to the target time point in the transition animation is the playing start frame, so that the skeleton position of the virtual character in the playing start frame is ensured to be consistent with the current skeleton position of the virtual character in the original state animation, and the action continuity of the virtual character is ensured.

As shown in fig. 7, according to the current foot bone position (including the current left foot bone position L1 and/or the current right foot bone position R1) of the virtual character at the current time point T1 in the moving animation, the target time point corresponding to the current foot bone position may be determined as T from the transition animation curve. And taking the animation frame corresponding to the target time point T in the switching animation as a playing start frame.

And 103, starting to play the switching animation from the playing start frame.

In this embodiment, after the play start frame is determined, the play of the original state animation is switched to the play of the switching animation, and the switching animation starts to be played from the play start frame, so that the virtual character is switched from the original state to the target state, and natural and smooth actions of the virtual character during switching are ensured.

All the above technical solutions can be combined arbitrarily to form the optional embodiments of the present application, and are not described herein again.

According to the state switching method of the virtual character, which is provided by the embodiment of the application, the current bone position of the virtual character is obtained from the currently played original state animation in response to the state switching instruction aiming at the virtual character; determining a playing start frame from a switching animation according to the current bone position, wherein the switching animation comprises a target state animation and a transition animation spliced before the target state animation, the transition animation comprises at least part of the original state animation, and the playing start frame is an animation frame in the transition animation; and starting to play the switching animation from the playing start frame. According to the embodiment of the application, the transition animation is added in the switching animation, so that when the virtual character is subjected to state switching, the animation frame corresponding to the current skeleton position of the virtual character is matched from the transition animation and used as the playing starting frame of the switching animation, the fluency of the action of the virtual character during switching is improved, the reality of the animation expression effect is improved, the matching is performed according to the skeleton position of the virtual character, the posture of the virtual character does not need to be identified, the animation resource amount and the data calculation amount are reduced, and the cost and the performance consumption are further reduced.

The embodiment of the application also provides a virtual role state switching method, which is applied to electronic equipment, wherein the electronic equipment provides a graphical user interface, and the graphical user interface has a virtual role. The specific process of the method can be as follows:

step 201, when it is detected that the virtual character needs to be switched from the advancing mode to the turning mode, determining a current left foot bone position corresponding to a current time point from a pre-established advancing animation curve, wherein the advancing animation curve is a corresponding relation curve of the left foot bone position and the time point of the virtual character in the advancing animation.

For example, the motion of the virtual character in the moving animation is right foot landing, left foot lifting → right foot lifting, left foot landing → right foot landing, and left foot lifting, and the moving animation curve is as shown in fig. 4. The moving animation is divided into a left foot transition animation (right foot falling to the ground, left foot rising → right foot rising, left foot falling to the ground) and a right foot transition animation (right foot rising, left foot falling to the ground → right foot falling, left foot rising). The left foot transition animation and the turning animation are spliced into the left foot switching animation, and the right foot transition animation and the turning animation are spliced into the right foot switching animation.

If the current left foot skeleton position is larger than the previous left foot skeleton position, the virtual character in the moving animation is moving forward to the right foot, and the right foot switching animation is selected as switching animation; and if the current left foot bone position is smaller than the previous left foot bone position, which indicates that the virtual character in the moving animation is at the left foot or the right foot, selecting the left foot switching animation as the switching animation.

As shown in fig. 10, the right foot switching animation curve is a corresponding relationship curve of the left foot bone position L of the virtual character in the right foot switching animation and the time point t, and the right foot transition animation curve is a curve between the time points t10 to t11 in the right foot switching animation curve.

If the switching animation is left foot switching animation, determining a target time point corresponding to the current bone position from a left foot transition animation curve; and if the switching animation is the right foot switching animation, determining a target time point corresponding to the current bone position from the right foot transition animation curve.

And step 205, starting playing the switching animation from the target time point.
