Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the present application provides a method for controlling a virtual machine, please refer to fig. 2, which is a flowchart of the method, and the method may include the following steps.
S201, determining a follow-up main body and an optimal follow-up distance and a follow-up distance range corresponding to the follow-up main body in the virtual scene.
The heel-shooting main body can be any virtual object in a virtual scene, for example, can be a virtual article, a virtual character, a specific limb part of the virtual character, a certain component of the virtual article and the like, and is not limited.
The follow-up subject may be manually specified by a user of a computer device (hereinafter referred to as a computer device) that performs virtual shooting, or may be automatically identified.
For example, a virtual object that is frequently displaced in a virtual scene may be determined as a heel-beat subject, a virtual object of a specific color in the virtual scene may be determined as a heel-beat subject, a virtual object of a maximum or minimum volume in the virtual scene may be determined as a heel-beat subject, and the like.
The virtual object that is displaced frequently is a virtual object whose cumulative moving distance per unit time (for example, 1 minute) is greater than a certain displacement distance threshold.
After determining the heel-strike subject, an optimal heel-strike distance and heel-strike distance range may be determined in at least one of the following ways:
in the first mode, a distance setting instruction of a user is obtained, and an optimal heel-beat distance and a heel-beat distance range of a heel-beat main body are determined according to the distance setting instruction;
and secondly, identifying the type of the heel-beating main body, and determining the optimal heel-beating distance and the heel-beating distance range corresponding to the heel-beating main body according to the type of the heel-beating main body.
In a first manner, the computer device may display a setup interface in which the user inputs values of the optimal following distance and following distance range, and then the computer device determines the input values as the optimal following distance and following distance range.
The optimal following distance and the following distance range may be in units of pixels, or may be in units of physical length units such as meters or centimeters.
In the second mode, the computer device may be preconfigured with a correspondence table of the type of the following main body, the optimal following distance and the following distance range, and after the computer device detects the type of the following main body through an algorithm for identifying the type of the object, the computer device searches the correspondence table for the optimal following distance and the following distance range corresponding to the type. This has the advantage that the efficiency of the method execution of the present embodiment can be improved.
S202, detecting whether the real-time distance between the virtual machine position in the locking state and the follow-up main body is within the follow-up distance range.
If the real-time distance is within the following distance range, step S203 is executed, and if the real-time distance is not within the following distance range, step S204 is executed.
The virtual machine position is the position of the virtual camera of the shooting follow-up main body.
The virtual machine position can be in a locking state or an unlocking state, and the specific state can be determined according to the configuration of a user or the state of the follow-up main body.
The state of the following main body can be specifically that the following main body moves at a speed, if the following main body moves at a speed lower than a preset motion threshold, the virtual machine position can be in an unlocked state, and if the following main body moves at a speed higher than or equal to the motion threshold, the virtual machine position can be in a locked state.
The virtual machine bit in the unlocked state can move under the control of the user, and if the user does not input an instruction for controlling the movement of the virtual machine bit, the virtual machine bit in the unlocked state does not move.
The virtual machine position in the locking state can move under the control of a user, and can also move along with the movement of the follow-up main body under the condition that the user does not input a corresponding instruction.
Under the locking state, the following shooting distance and the shooting angle of the virtual machine position are locked at the same time, and the virtual machine position automatically follows the following shooting main body and keeps the following shooting distance and the shooting angle. The user has no virtual machine position control authority during locking. The virtual machine position can be unlocked to keep pace with the shooting distance and the shooting angle.
After unlocking, the virtual machine is in an unlocking state, and at the moment, a user can freely control the virtual machine, lock the heel-shooting main body again, and reset the optimal heel-shooting distance and the heel-shooting distance range for the heel-shooting main body.
In step S202, three-dimensional space coordinates corresponding to the virtual machine position and three-dimensional space coordinates of the following main body may be detected, and then a distance between the two three-dimensional space coordinates is calculated, where the obtained result is used as a real-time distance. The detection mode of the three-dimensional space coordinates of the virtual machine position and the heel-shooting main body in the virtual scene can be referred to related prior art documents, and will not be repeated.
S203, controlling the virtual machine to move according to the first movement instruction of the user.
The first movement instruction for controlling the movement of the virtual machine position by the user can be obtained in various ways.
As one example, a control handle may be connected to the computer device, and a user may move a control lever on the control handle, the computer device obtaining a first movement instruction based on the amplitude and direction of the swing of the control lever.
As another example, a keyboard may be connected to the computer device, and the user may press a key on the keyboard for controlling movement of the virtual machine location, and the computer device obtains the first movement instruction according to the key pressed by the user and the time of continuous pressing.
S204, identifying a control instruction of a user.
In step S204, the computer device may display a control interface including a plurality of options, prompt the user to select one of the options, and then identify a corresponding control command according to the selected option of the user.
For example, when the user selects the first option, the computer device obtains the first control command, when the user selects the second option, the computer device obtains the second control command, and when the user selects the third option, the computer device obtains the third control command.
S205, when the control instruction is a first control instruction, controlling the virtual machine to move according to the real-time distance, the moving speed and the moving direction of the follow-up main body.
The specific embodiment of step S205 may include:
determining whether the absolute value of the difference between the real-time distance and the optimal follow-up distance is smaller than a preset follow-up threshold;
if the absolute value is smaller than the follow-up threshold, controlling the virtual machine position to move according to the moving speed and the moving direction of the follow-up main body;
if the absolute value is larger than or equal to the heel-beat threshold value, determining the movement speed of the virtual machine position according to the absolute value and the movement speed of the heel-beat main body, wherein the movement speed of the virtual machine position is larger than the movement speed of the heel-beat main body;
and controlling the virtual machine position to move according to the moving speed of the virtual machine position and the moving direction of the follow-up main body.
The absolute value of the difference between the real-time distance and the optimal following distance can be represented by the formula (1), when the formula (1) satisfies the inequality (2), the multiplying factor R can be determined to be equal to 1, then the moving speed of the following main body is multiplied by the multiplying factor to obtain the moving speed of the virtual machine position, the moving direction of the following main body is determined to be the moving direction of the virtual machine position, the virtual machine position is controlled to move along with the following main body according to the moving speed and the moving direction of the virtual machine position, and at the moment, the moving speed and the moving direction of the virtual machine position are consistent with the moving speed and the moving direction of the following main body.
Wherein Disn represents the real-time distance, dis0 represents the optimal following distance, and Dismax represents the upper limit of the following distance range. The following distance range may not be set to a lower limit, and may be set to a lower limit of 0.
When equation (1) satisfies inequality (3), the multiplying power coefficient R can be calculated according to equation (4) by the absolute value, then the multiplying power coefficient is multiplied by the moving speed of the following main body to obtain the moving speed of the virtual machine position, the moving direction of the following main body is determined to be the moving direction of the virtual machine position, the virtual machine position is controlled to move along with the following main body according to the moving speed and the moving direction of the virtual machine position, at the moment, the moving speed of the virtual machine position is larger than the moving speed of the following main body, and the moving direction of the virtual machine position is consistent with the moving direction of the following main body, so that the distance between the virtual machine position and the following main body can be shortened rapidly.
Wherein, K, x and T can be preset adjustable parameters for comprehensively controlling the elastic strength when the virtual machine position distance exceeds the follow-up distance range. The values of these parameters may be fixed values set in advance, or may be dynamic values set dynamically according to the acceleration of the following subject, for example, the larger the acceleration of the following subject, the larger the values of these parameters may be.
Optionally, when controlling the virtual machine bit in the manner of S205, the computer device may further perform the following steps:
and if the target control instruction of the user for the virtual machine position is continuously obtained within the preset duration threshold, releasing the locking state of the virtual machine position, and controlling the virtual machine position to move according to the target control instruction.
That is, if the user continuously inputs a target control instruction for controlling the movement of the virtual machine, for example, continuously pressing a key for controlling the movement of the virtual machine, or continuously toggling a lever for controlling the movement of the virtual machine, and the duration reaches a preset duration threshold during the control of the virtual machine by the computer device in the manner of S205, the computer device may release the locked state of the virtual machine, and control the movement of the virtual machine according to the target control instruction for controlling the movement of the virtual machine by the user in the manner of S207.
The duration threshold may be configured according to the needs of the user, for example, to be 2 seconds.
In some alternative embodiments, during the control of the virtual machine bit movement by the computer device in the manner of S205, the following steps may also be performed:
after the virtual machine position is controlled to move to the first position according to the moving speed and the moving direction of the follow-up main body, the virtual machine position is controlled to move in a fine adjustment range taking the first position as the center according to a third moving instruction of a user.
The fine tuning range may be a spherical range centered on a first position to which the virtual machine moves in the virtual scene and having a radius equal to a preset fine tuning distance.
The fine adjustment distance can be preset by a user according to actual conditions.
Optionally, when the virtual machine is controlled to move within the trimming range, the moving distance and the moving direction of the virtual machine in the whole virtual scene can be determined according to a third moving instruction of the user, then the ratio between the size of the trimming range and the size of the whole virtual scene is calculated, the moving distance in the whole virtual scene is reduced to the moving distance within the trimming range according to the ratio, and finally the virtual machine is controlled to move within the trimming range according to the moving direction and the moving distance within the trimming range.
For example, according to a third movement instruction of the user, the virtual machine position may be translated to the left by 20 cm in the whole virtual scene, the ratio between the calculated size of the fine tuning range and the size of the whole virtual scene is 1:20, and then the computer device may reduce the movement distance of 20 cm in the whole virtual scene to 1 cm according to the ratio, and then control the virtual machine position to translate to the left by 1 cm in the fine tuning range.
S206, when the control instruction is a second control instruction, determining an optimal following shooting position according to the optimal following shooting distance and the position of the following shooting main body, and resetting the virtual machine position to the optimal following shooting position.
In step S206, a spherical surface with the position of the heel-beat main body as the center and the optimal heel-beat distance as the radius may be determined in the virtual scene according to the optimal heel-beat distance and the position of the heel-beat main body, then a position is selected on the spherical surface to determine the optimal heel-beat position, and then the virtual machine position is reset to the optimal heel-beat position.
The strategy for selecting the optimal follow-up position may be to select a position closest to the current virtual machine position on the sphere as the optimal follow-up position, or may be to determine the optimal follow-up position according to the shooting requirement of the follow-up main body.
For example, if the virtual camera needs to capture the back of the heel-strike subject, then the position on the sphere that faces the back of the heel-strike subject may be selected as the optimal heel-strike position.
Optionally, the shooting angle of the virtual camera located at the optimal following position after reset may be determined according to the range of the following main body. Specifically, the virtual camera can be rotated to the position of the lens axis to coincide with the connecting line of the shooting main body, and the lens faces the shooting angle of the shooting main body.
Resetting the virtual machine position, setting the distance between the virtual machine position and the follow-up main body as the preset optimal follow-up distance, resetting the shooting angle to align with the follow-up main body, after the reset, the user can freely control the displacement, the advancing direction and the shooting angle of the virtual machine.
Optionally, after the virtual machine position is reset to the optimal follow-up position, the virtual machine position can be moved according to a control instruction of a user, specifically, at this time, the virtual machine position can be moved according to displacement, a travelling direction and a shooting angle designated by the user.
The method comprises the steps that the virtual machine position is reset to the optimal follow-up position, namely, the computer equipment directly deletes the virtual camera on the current virtual machine position, then a new virtual camera is arranged at the optimal follow-up position, and parameters of the new virtual camera, such as aperture size, flash lamp duration, exposure and the like, are consistent with the deleted virtual camera.
S207, when the control command is the third control command, the locking state of the virtual machine position is released, and the virtual machine position is moved according to the second movement command of the user.
After the locking state is released, a user can freely control the displacement, the advancing direction and the shooting angle of the virtual machine.
The second movement instruction is obtained in a manner consistent with the first movement instruction, and will not be described again.
The beneficial effects of this embodiment lie in:
when the real-time distance between the virtual machine position and the follow-up shooting main body exceeds the follow-up shooting distance range, the virtual machine position can be controlled to move along with the movement of the follow-up shooting main body according to the real-time distance, the movement speed and the movement direction of the follow-up shooting main body and a control instruction of a user, the problem that the virtual camera follows the shooting in the virtual shooting can be solved without controlling the movement of the real camera in the real shooting field, and therefore the problem that the virtual machine position is difficult to control to reach the optimal shooting position due to insufficient movable space of the real camera is solved.
