The present application may be embodied or carried out in other specific embodiments, and the details of the present application may be modified or changed from various points of view and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.
It should be noted that, the illustrations provided in the following embodiments merely illustrate the basic concepts of the application by way of illustration, and only the components related to the application are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complex.
The embodiment of the application provides a method and a device for preventing a virtual person from falling in a virtual scene, a storage medium and a terminal. The following will explain in detail the principle and implementation of the anti-drop method and device for a virtual person in a virtual scene, the storage medium and the terminal according to the embodiment by referring to the accompanying drawings, so that a person skilled in the art can understand the anti-drop method and device for a virtual person in a virtual scene, the storage medium and the terminal according to the embodiment without creative labor.
As shown in fig. 1, the embodiment provides a method for preventing a virtual person from falling in a virtual scene, which includes the following steps.
In step S101, the directors are set in all directions of actions of the dummy.
And setting pointing marks on all action directions of the virtual person respectively to serve as a height comparison basis for later judging whether the virtual person walks to the edge of the map of the affiliated virtual scene. Specific virtual person normal action directions include directions on a virtual person cross section, such as forward, backward, leftward, rightward, etc., for which arbitrarily shaped directors can be provided along the virtual person action direction. In a specific virtual scene, a virtual person can also set an oblique action direction such as an oblique upward direction, an oblique downward direction and the like, and pointing marks with arbitrary shapes can be set for the action direction, but in order to facilitate the judgment of whether a subsequent virtual person walks to the edge of a map, the pointing marks of the action direction are limited pointing marks, such as lines which cannot be set to extend along the oblique direction in a wireless manner. While for some virtual scenes upward and downward directions of action can be set, the pointing object of this type of direction of action should also be set as a limited pointing object.
The virtual person should be set in the center of all the pointing marks as much as possible, and in order to ensure that the pointing marks can reach the virtual person in advance and then move to the position, the distance between all the pointing marks and the central axis of the virtual person needs to be set, at least greater than or equal to the maximum single movement distance of the virtual person. For example, if the virtual human action operations include a walking operation, a jumping operation, and a running operation, if the step width of a single walking operation is 1 unit, the step width of a single jumping operation is 3 units, and the step width of a single running operation is 2 units, then it is necessary to set the distance between each pointing mark and the virtual human to be at least greater than or equal to 3 units.
For example, the direction of action of the dummy person may be set to 4 directions, forward, backward, leftward and rightward, respectively. The preferred pointer may be provided in a cube shape as shown in fig. 4. While the pointer may be provided in other reasonable shapes, it is not limited thereto. The distance between the pointing targets and the central axis of the virtual person can also be adjusted based on actual conditions so as to meet the minimum distance setting of various distances from the edge of the map in all directions. For example all pointing distances from the virtual human central axis are all the same, all different or partly the same.
For another example, the action direction of the dummy person may be set to 8 directions of forward, front left 45 degrees, front right 45 degrees, backward, rear left 45 degrees, rear right 45 degrees, and left and right, respectively. Preferably, the directors can be arranged in a cube shape, and the upper surfaces of all the directors form a hollow square, as shown in fig. 2; preferably, all the directors are also arranged in an arch shape, and the upper surfaces of all the directors form a circular ring shape, as shown in fig. 3. While the pointer may be provided in other reasonable shapes, it is not limited thereto. The distance between the pointing targets and the central axis of the virtual person can also be adjusted based on actual conditions so as to meet the minimum distance setting of various distances from the edge of the map in all directions. For example all pointing distances from the virtual human central axis are all the same, all different or partly the same.
Step S102, obtaining the action operation of the virtual person at the next moment in real time to serve as a pre-judging action operation, obtaining the action direction from the pre-judging action operation to serve as a pre-action direction, taking the pointing object corresponding to the pre-action direction as a target pointing object, judging whether the maximum height difference between the target pointing object and an object below the target pointing object is larger than a preset height threshold, if so, executing the pre-judging action operation, and otherwise, stopping the pre-judging action operation.
In the normal course of action of the virtual person, the action operation of the virtual person at the next moment needs to be acquired in real time so as to be convenient for real-time judgment. Specifically, the action operation of the virtual person at the next moment acquired in real time is taken as a pre-judging action operation, and then the direction of the action operation is acquired from a preprocessing operation, for example, the action operation is forward or backward. The action direction in the pre-determined action operation is taken as a pre-action direction, and the target pointing object in the pre-action direction is determined as a target pointing object. And judging the maximum height difference between the target pointing object and the object below the target pointing object, namely that a plurality of objects possibly exist below the target pointing object, and judging whether the maximum height difference is larger than a preset height threshold value or not only by acquiring the maximum height difference between the target pointing object and the object below the target pointing object, if so, executing the pre-judging action operation, so that the setting of the target pointing object does not influence the normal action operation of the virtual person at all. If the maximum height difference is larger than the preset height threshold, the virtual person is indicated to have reached the edge position of the virtual scene to which the virtual person belongs, and the execution of the preset judging operation is prevented, namely the virtual person is kept in situ, and the virtual person is further prevented from walking to the space outside the virtual scene map.
Preferably, the action operation type includes a walk operation, a jump operation, and a running operation. The action operation may be other reasonable action operation of the dummy, which will not be described in detail herein.
The height difference calculation in the above process is performed in the gravity direction of the virtual scene to which the virtual person belongs, so as to avoid the influence of factors such as scene and posture on the calculation of the maximum height difference. When the virtual person walks to the edge of the virtual scene map (i.e. the pointing device is outside the virtual scene map), the calculated height difference should be infinite since no floor is provided outside the map, and further no objects are placed. All scenes in the virtual scene map are provided with floors, for example, the bottoms of lakes, seas and the like in the virtual scene should be provided with corresponding floors, if no other objects exist under the target pointing mark, at least floors exist, therefore, the maximum height difference value is necessarily present, and the preset height threshold value should be met. The preset height threshold in this embodiment needs to be set to be greater than the maximum design height of the virtual scene, and this setting can avoid influencing the virtual person to execute operations of increasing the interest of the scene such as jumping from the roof due to the design of the preset height threshold being too small.
The invention also sets the pointing indicator to be transparent and in a collision-free state, the complete lens state setting can not influence the image of the virtual person, the collision-free state setting can not influence the normal behavior of the virtual person, and the setting can not completely sense the existence of the pointing indicator for controlling the user of the virtual person and can not influence the user experience.
According to the anti-drop method for the virtual person in the virtual scene, the pointing marks are arranged in each action direction of the virtual person, the distance between the pointing marks and the central axis of the virtual person is set to be larger than the maximum action step of the virtual person, so that the pointing marks are positioned at the action positions behind the virtual person in advance, whether the virtual person moves outside the map in the next step can be judged based on the distance between the pointing marks and the floor in the virtual scene, and further the next step of movement of the virtual person is controlled. The arrangement does not need to be provided with a barrier when making the map, and reduces a lot of workload for designers. The invention can also set the distance between each pointing mark and the virtual human central axis based on the actual situation so as to meet the minimum distance setting of the edges of the map in each direction. The invention also sets the pointing mark as transparent non-collision state, thereby not affecting the virtual human figure.
As shown in fig. 5, the embodiment provides an anti-falling device for a virtual person in a virtual scene, which includes a pointer setting module and a pre-judging module for action operation.
The pointer setting module is used for setting pointers in all action directions of the virtual person respectively, and the distance between each pointer and the virtual person is larger than or equal to the maximum action distance of the virtual person in a single time.
The action operation pre-judging module is used for acquiring the action operation of the virtual person at the next moment in real time to serve as a pre-processing action operation, acquiring the action direction from the pre-processing action operation to serve as a pre-action direction, and taking the target corresponding to the pre-action direction as a target, judging whether the maximum height difference between the target and an object under the target is larger than a preset height threshold, if so, executing the pre-processing action operation, otherwise, stopping the pre-processing action operation.
According to the anti-drop device for the virtual person in the virtual scene, the pointing marks are arranged in each action direction of the virtual person, the distance between the pointing marks and the central axis of the virtual person is set to be larger than the maximum action step of the virtual person, so that the pointing marks are positioned at the action positions behind the virtual person in advance, whether the virtual person moves outside the map in the next step can be judged based on the distance between the pointing marks and the floor in the virtual scene, and further the next step of movement of the virtual person is controlled. The arrangement does not need to be provided with a barrier when making the map, and reduces a lot of workload for designers. The invention can also set the distance between each pointing mark and the virtual human central axis based on the actual situation so as to meet the minimum distance setting of the edges of the map in each direction. The invention also sets the pointing mark as transparent non-collision state, thereby not affecting the virtual human figure.
