The components of the embodiments of the present application, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

In the existing first-person shooter game, the orientation of a handheld weapon (such as a gun) of a virtual character and the orientation of a virtual camera are bound, that is: the pointing direction of the handheld weapon and the shooting direction of the virtual camera are the same at the same moment, and when any one of the pointing direction of the handheld weapon and the shooting direction of the virtual camera changes, the other one also changes the same, but the true situation is that the pointing direction of the handheld weapon changes, inertia exists, and the mode embodied in the game picture is that the shooting direction of the virtual camera changes only after the change of the handheld weapon, so the setting that the pointing direction of the handheld weapon and the orientation of the virtual camera are bound in the prior art can make the game effect exhibited by the game picture harder, namely: the inertia lag effect is not shown, so that the game picture is not smooth relatively, and the operation hand feeling of the player on the hand-held weapon is poor in the game process.
In order to enable a game picture to show an inertial hysteresis effect and improve the flow of the game picture, the embodiment of the application provides a game picture display method, a device, equipment and a storage medium, in the application, a sighting center and a shooting visual angle of a virtual camera synchronously change in a game scene, under a first person visual angle, when the shooting visual angle changes, a deviation action posture of a virtual character under the current shooting visual angle is determined firstly, then the deviation action posture is superposed on a basic action posture of the virtual character under the current shooting visual angle, at the moment, the reference of the basic action posture of the virtual character changes, but the sighting center and the shooting visual angle both change, namely: the action posture of the virtual character is changed before the aiming center and the shooting visual angle, and the virtual weapon is held by the virtual character, so that the orientation of the virtual weapon is synchronously changed after the action posture of the virtual character is changed, further, the orientation of the virtual weapon is changed before the aiming center and the shooting visual angle, so that the orientation of the virtual weapon in a game picture shot by the virtual camera does not point to the aiming center, and the continuous animation effect of a plurality of frames of game pictures is that the shooting visual angles of the aiming center and the virtual camera are changed the same after the orientation of the virtual weapon is changed, so that the orientation and the shooting visual angle of the virtual weapon show a certain inertial lag effect, and the continuous game pictures are smoother and closer to the real situation, thereby being beneficial to improving the operation hand feeling of a player on the holding weapon in the game process.
It should be noted in advance that the virtual weapon is hung on the virtual character, and the change of the action posture of the virtual character drives the change of the orientation of the virtual weapon.
Example one
Fig. 1 is a schematic flow chart of a game picture display method according to an embodiment of the present application, in which a game picture shot by a virtual camera is displayed through a display device, the game picture displays a part of a game scene, the game picture at least includes a virtual weapon, a partially-presented virtual character, and an aiming centroid, and the aiming centroid and the shooting angle of view of the virtual camera change synchronously in the game scene, and the game picture display method includes the following steps:
And 102, determining the offset action posture of the virtual character under the current shooting visual angle according to the first direction change value and the first speed change value.
And 103, superposing the shifting action posture to the basic action posture of the virtual character under the current shooting visual angle.
And 104, displaying a game picture shot by the virtual camera under the current shooting visual angle as a current frame on the display device.
Specifically, in a real situation, when an object moves, the object has an inertial characteristic, and the larger the direction and speed change is, the more obvious the inertial effect is, in order to make a game picture exhibit an inertial lag effect, and make the game picture more real, it is necessary to set the aiming centroid and the shooting angle of view of the virtual camera to change synchronously in the game scene. Under a first person's visual angle, when a shooting visual angle of a virtual camera changes, a first direction change value and a first speed change value of the current virtual camera need to be determined, and a direction change rate of the virtual camera can be determined through the first direction change value and the first speed change value, so that a shift action attitude of a virtual character under the shooting visual angle of the current virtual camera can be determined according to the first direction change value and the first speed change value, and the shift action attitude can represent a variation amount of an action attitude of the virtual character when the shooting visual angle changes, and then the shift action attitude is superposed on a basic action attitude of the virtual character under the current shooting visual angle, and at this time, an action attitude of the virtual character after the change according to the shift action attitude under the current shooting visual angle can be obtained by taking the basic action attitude of the virtual character as a reference, namely: the motion pose of the virtual character in the next frame game picture can be obtained, the orientation of the aiming centroid in the next frame game picture is the same as the orientation of the aiming centroid in the current frame game picture, but the motion pose of the virtual character in the next frame game picture is different from the motion pose of the virtual character in the current frame game picture by the obtained shift motion pose, and the orientation of the virtual weapon is not directed to the aiming centroid but has a deviation corresponding to the shift motion pose.
For example, fig. 2 is a schematic diagram of a game picture provided by an embodiment of the present application, fig. 3 is a schematic diagram of another game picture provided by an embodiment of the present application, fig. 2 is a game picture when a shooting angle of a virtual camera is not changed, at this time, an orientation of a virtual weapon points to a sighting center, when the shooting angle of the virtual camera is changed, a shift action posture of the virtual character at the current shooting angle is determined according to a first direction change value and a first speed change value of the current virtual camera, and then the shift action posture is superimposed on a basic action posture of the virtual character at the current shooting angle, at this time, the game picture is obtained as shown in fig. 3, in the game picture shown in fig. 3, an orientation of the virtual weapon does not point to the sighting center any more, but a deviation corresponding to the shift action posture occurs, when the shooting angle of the virtual camera is continuously changed, in a next frame of game picture, the action posture of the virtual character continues to be superimposed on a basis of the previous frame of image, and thus the shooting angle of the virtual weapon in the next frame of game picture shows a more smooth change of the orientation of the virtual weapon, thereby improving a shooting angle of the virtual weapon when the virtual camera is changed, and the shooting angle of the virtual camera is changed, and the virtual weapon is more favorable to follow-up to a change of the virtual weapon in a situation that the virtual weapon in a shooting angle of the virtual weapon.
In a possible embodiment, fig. 4 is a schematic flow chart of another game screen display method provided in the first embodiment of the present application, and as shown in fig. 4, when step 102 is executed, the method can be implemented by:
And 402, obtaining the offset action attitude of the virtual character under the current shooting visual angle according to the first direction change value after the smoothing processing and the first speed change value after the smoothing processing.
Specifically, in order to avoid the situation that the shooting angle changes greatly in a unit time to cause that the game pictures of two adjacent game images are similar to frame skipping, smoothing processing needs to be performed on a first direction change value and a first speed change value to determine whether the first direction change value exceeds a preset direction change value, if the first direction change value exceeds the preset direction change value, the first direction change value needs to be replaced by the preset direction change value, and whether the first speed change value exceeds a preset speed change value, and if the first speed change value exceeds the preset speed change value, the first speed change value needs to be replaced by the preset speed change value, and then the first direction change value after smoothing processing and the first speed change value after smoothing processing are used for obtaining the offset action posture of the virtual character at the current shooting angle.
It should be noted that, the specific preset direction change value and the preset speed change value may be set according to actual needs, and are not specifically limited herein.
In a possible embodiment, fig. 5 is a schematic flowchart of another game screen display method provided in the first embodiment of the present application, and as shown in fig. 5, when step 102 is executed, the method may be implemented by:
Specifically, a standard deviation motion attitude is pre-established, wherein a second direction change value and a second speed change value of a shooting angle of view corresponding to different standard deviation motion attitudes are different, that is: the method comprises the steps of obtaining standard deviation action postures corresponding to different second direction change values and second speed change values of a shooting visual angle in advance, using the second direction change values, the second speed change values and the standard deviation action postures which have corresponding relations as a group of key frame data, using two-dimensional coordinates formed by the second direction change values and the second speed change values in the key frame data as different key frame points, and mapping the key frame points into a two-dimensional graph, wherein the two-dimensional graph comprises a plurality of key frame points, after a target two-dimensional coordinate formed by the first direction change values and the first speed change values is mapped into a specified two-dimensional graph, the two-dimensional graph comprises a target point, the two-dimensional graph comprises the key frame points and points corresponding to the target two-dimensional coordinate, and after the two-dimensional graph comprising the target point is obtained, the deviation action posture of the virtual character under the current shooting visual angle can be determined according to the standard deviation action posture corresponding to the key frame points adjacent to the points corresponding to the target two-dimensional coordinate.
It should be noted that, the specific preset number can be set according to actual needs, for example: one key frame point closest to the target point may be selected, or three key frame points closest to the target point may be selected, and the specific number is not specifically limited herein. Meanwhile, the number and density of the key frame points may be set according to actual needs, and are not specifically limited herein.
In a possible embodiment, fig. 6 is a schematic flow chart of another game screen display method provided in the first embodiment of the present application, where the preset number is three, as shown in fig. 6, and when step 503 is executed, the method can be implemented by:
and 601, determining the distances between the target point and the three key frame points respectively.
Specifically, the distances between the target point and each keyframe point represent the similarity between the shift action pose corresponding to the target point and the standard shift action pose corresponding to each keyframe point, wherein the closer the distance is, the closer the month is, the more similar the distance is, and since the obtained three keyframe points are the three keyframe points closest to the target point, the shift action pose corresponding to the target point and the standard shift action poses corresponding to the three keyframe points are both similar but not completely the same, so that after the distances between the target point and the three keyframe points are determined, weights can be assigned to the standard shift action poses corresponding to the three keyframe points based on the distances, wherein the smaller the distance is, the higher the weights are, and then the shift action poses corresponding to the three keyframe points are weighted and averaged to obtain the shift action pose.
For example: after the vector corresponding to each standard deviation action posture is multiplied by the weight of the standard deviation action posture, the three multiplication results are added, finally, the addition result is averaged, and the movement action posture corresponding to the finally obtained vector is taken as the deviation action posture.
For another example: the standard deviation action postures corresponding to the three key frame points can be weighted and averaged through the following formula to obtain the deviation action posture:
P＝(P0×D0+P1×D1+P2×D2)/(D0+D1+D2)；
wherein, P0, P1, P2 represent 3 key frame points respectively, D0, D1, D2 are reciprocal of distance from the target point to the three key frame points respectively, and D0, D1, D2 are weights of the corresponding key frame points respectively.
In one possible embodiment, the key frame corresponding to each key frame point included in the two-dimensional map is selected from consecutive image frames generated when the photographing angle of view of the virtual camera is changed according to a specified operation.
Specifically, in order to make the obtained offset action pose more accurate, the shooting angle of the virtual camera needs to be continuously changed according to a specified operation, a specified number of key frames are selected from the continuously changed image frames, and corresponding key frame points are determined according to the selected key frames, for example: the key frame point can be determined according to the direction change value and the speed change value corresponding to each selected key frame, and the action posture in the key frame is used as the standard deviation action posture corresponding to the key frame point.
In one possible embodiment, the consecutive image frames are obtained by performing a moving view angle operation within a range of 360 ° on a photographing view angle of the virtual camera, and the number of the moving view angle operations is at least one.
Specifically, in the actual game process, the direction change and the speed change of the shooting angle of view of the virtual camera may be arbitrary, so when consecutive image frames are obtained according to the designated operation, a plurality of different operations may be performed, wherein the angle of view change of 360 ° is completed through a plurality of sub-operations in each operation, in this way, consecutive image frames under a plurality of angle of view changes may be obtained, in the actual game process, after the angle of view changes, a key frame point relatively similar to the change may be found in the two-dimensional map, for example, fig. 7 is a schematic diagram of a two-dimensional map provided in the embodiment of the present application, the three designated operations may be performed, and the angle of view change in each operation is 360 °, and the obtained three groups of consecutive image frames are mapped to the key frame point in the two-dimensional map as shown in fig. 7.
It should be noted that fig. 7 is only a schematic illustration and is not a limitation to the present application, and the specific operation times and the acquisition density of consecutive image frames may be set according to actual needs, and are not specifically limited herein.
In a feasible implementation scheme, the direction change value during the operation of moving the view angle is not greater than a preset direction change value, and the speed change value during the operation of moving the view angle is not greater than a preset speed change value, so that the change amplitude of the standard deviation action attitude corresponding to each key frame point in the two-dimensional graph is relatively small, the change amplitude of the finally obtained deviation action attitude is relatively small, the occurrence of a situation similar to frame skipping on adjacent game pictures can be avoided, and the display effect of the game pictures can be improved.
In one possible embodiment, the virtual item associated with the virtual weapon and the shooting perspective of the virtual camera in the game screen change synchronously in the game scene.
In particular, a virtual weapon in a game may be associated with other virtual items, such as: virtual props associated with virtual firearms may include: for the virtual props to exhibit the effect of inertial lag, the virtual props associated with the virtual weapons and the shooting angles of the virtual cameras need to be changed synchronously in the game scene, that is: the virtual items associated with the virtual weapon track the same changes as the virtual weapon occurs.
