It should be noted that the system schematic diagram of the control system of the virtual lens shown in fig. 1a is only an example, the control system of the virtual lens and the scene described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems with the evolution of the control system of the virtual lens and the appearance of new service scenes.

In the present embodiment, the description will be made from the perspective of a control device of a virtual lens, which may be specifically integrated in a computer apparatus having a storage unit and a microprocessor mounted thereon and having an arithmetic capability.

Referring to fig. 1b, fig. 1b is a schematic flowchart illustrating a control method for a virtual lens according to an embodiment of the present disclosure. The control method of the virtual lens comprises the following steps:

in step 101, a graphical user interface is displayed, where the graphical user interface includes at least a part of a virtual scene and a virtual character located in the virtual scene, and the graphical user interface is an interface displayed by capturing the virtual scene and the virtual character through a virtual lens associated with the virtual character.

The graphical user interface is displayed as a three-dimensional virtual scene in a game scene, and the three-dimensional virtual scene is a virtual scene provided by an application program when the application program runs on a terminal, and can be a simulation scene of a real world, a semi-simulation semi-fictional scene or a pure fictional scene. The scene picture displayed on the graphical user interface is the scene picture displayed when the virtual object observes the three-dimensional virtual scene. A user controls a virtual object in a game scene through a terminal, the virtual object can observe a three-dimensional virtual scene through a virtual lens, for example, in an FPS game, when the virtual lens is positioned at a first person angle, the virtual lens is positioned at the head or the neck of a target virtual object, and only the arm part of a virtual character can be displayed in a graphical user interface; when the virtual lens is positioned behind the target virtual object in the third person perspective, only the upper body part of the virtual character can be displayed in the graphical user interface. The graphical user interface is a scene picture presented by observing the three-dimensional virtual scene through the virtual lens at a certain viewing angle.

Specifically, please refer to fig. 1c, and fig. 1c is a schematic diagram of a graphical user interface provided in an embodiment of the present application. The graphic user interface is presented by a screen of the computer device 2000, and includes a virtual character 10 manipulated by a user in the graphic user interface, the virtual character 10 is configured with a virtual firearm, firing through the virtual firearm, and a firing aiming identification 20 for assisting the virtual firearm in aiming, a cursor control 30 for prompting the user of current direction information of the virtual character 10, a movement control 40 for controlling the virtual character 10 to move in a three-dimensional virtual environment, an aiming control 50 that the virtual character 10 can use in an attack, and a map control 60 for prompting the user of a position of the virtual character 10 in the three-dimensional virtual environment, and a firing control 70 for controlling the virtual character 10 to fire the firearm in the three-dimensional virtual environment, and the like. An indication control 31 is further disposed in the direction control 30, and is used for indicating the direction in which the virtual character 10 is located in the cursor control 30. It is understood that the graphical user interface may include not only the above identifiers and controls, but also other functional controls or identifiers, which are determined according to specific game content, and is not limited herein.

In step 102, a current collecting direction of the virtual shot is obtained when the virtual character shoots each time.

When a user clicks a firing control or controls a virtual character to use the configured virtual firearm for attack through a physical key such as a mouse and a keyboard, the current acquisition direction of the virtual lens is acquired. The current acquisition direction is the aiming direction of the virtual bullet in the virtual firearm before the virtual bullet is fired.

In step 103, a rotation direction, an initial rotation speed of rotating to the rotation direction, and a rotation acceleration of rotating to the current collection direction are assigned to the virtual lens.

The recoil effect of the virtual lens refers to a lens shaking rule generated by the virtual firearm when being fired, so that the orientation of the lens is changed. The positions of the virtual gun and the shooting aiming mark are not influenced by the effect of a shooting lens and still keep unchanged at the central position of the picture. The basic principle is that a rotation direction is given to the virtual lens when the virtual lens is triggered, the virtual lens starts to move at a rotation initial speed rotating towards the rotation direction, and a rotation acceleration opposite to the rotation direction is applied to pull the virtual lens towards an initial origin position. Therefore, the effect that the virtual lens rotates towards the rotating direction firstly and then rotates towards the current collecting direction reversely is formed.

In step 104, the virtual lens is controlled to rotate towards the rotation direction based on the rotation direction, the initial rotation speed and the rotation acceleration, and when the virtual lens does not rotate towards the rotation direction any more, the virtual lens is controlled to rotate towards the current acquisition direction until the acquisition direction of the virtual lens is the current acquisition direction.

In order to avoid that the acquisition direction of the virtual lens returns to the initial acquisition direction quickly in the continuous shooting process, when the virtual lens rotates towards the current acquisition direction due to the fact that the initial rotation speed allocated to the virtual lens is shot next time in the continuous shooting process, the product of the initial rotation speed and the specified numerical value is calculated, and the result is used as the actual initial rotation speed of the next shooting.

Specifically, in order to design a trajectory formed after virtual shooter shoots, a rotation direction configured for the virtual lens for each shooting in a continuous process, for example, first rotating to the left and then rotating to the right, may be set, so as to form a customized trajectory.

The player can autonomously control the acquisition direction of the virtual lens in the shooting process, so that the screen sliding value of the player in the process of autonomously controlling the acquisition direction of the virtual lens can be recorded, the screen sliding value is converted into the rotation angle of the virtual lens, and the rotation angle is superposed, so that the acquisition direction after the shooting process is prevented from being misaligned with the current acquisition direction.

Wherein, after having been allocated rotation direction, initial slew velocity and transmission acceleration for virtual camera lens, control virtual camera lens according to initial slew velocity to the slew direction rotates, because carry out the pivoted in-process to the slew direction, initial slew velocity can receive reverse slew acceleration's influence for the pivoted speed reduces gradually, when being 0 to slew direction pivoted slew velocity, receives slew acceleration's influence to the current direction of gathering and rotates, thereby realizes that virtual camera lens keeps away from current direction of gathering earlier along with virtual firearms ' shooting process, the effect that is close to current direction of gathering afterwards.

In some embodiments, the step of controlling the virtual lens to rotate towards the rotation direction based on the rotation direction, the initial rotation speed, and the rotation acceleration, and when the virtual lens does not rotate towards the rotation direction, controlling the virtual lens to rotate towards the current collecting direction until the collecting direction of the virtual lens is the current collecting direction includes:

(1) Calculating the first frame rotating speed of the first shooting effect frame in the shooting effect calculation period based on the initial rotating speed and the rotating acceleration;

(2) Determining the total rotation angle of a shooting effect calculation period according to the rotation speed of the first frame;

(3) Determining a rotation angle corresponding to each display frame of the virtual lens in a shooting effect frame duration based on a frame rate of a client;

(4) And controlling the virtual lens to rotate along with the display of each display frame according to the corresponding rotation angle of each display frame until the acquisition direction of the virtual lens is the current acquisition direction.

Wherein, the shooting effect calculation period can be set to 1/30 second, and the first frame rotation speed of the first shooting effect frame in the shooting effect calculation period is calculated every 1/30 second based on the initial rotation speed and the rotation acceleration. The total rotating angle of the virtual lens, which can rotate from the current shooting effect calculation period to the next shooting effect calculation period, can be obtained based on the rotating speed of the first frame.

Specifically, since the actual display process virtual lens rotation angle is determined based on the frame rate of the player's client, and the frame rate of the client is greater than 30 frames per second, it is equivalent to that there are multiple frames of display frames in one shooting effect calculation period. Therefore, the rotation angle of the virtual lens corresponding to each display frame within the duration of a shooting effect frame needs to be determined according to the frame rate of the client. And after the rotation angle corresponding to each display frame is calculated, controlling the virtual lens to rotate along with the display of each display frame according to the rotation angle corresponding to each display frame until the acquisition direction of the virtual lens is the current acquisition direction.

In some embodiments, the step of determining, based on the frame rate of the client, a rotation angle corresponding to each display frame of the virtual lens within a duration of a shooting effect frame includes:

(1) Determining the display time difference between the current display frame and the previous display frame;

(2) Comparing the display time difference with the shooting effect calculation period to obtain a comparison result;

(3) And determining the corresponding rotation angle of each display frame of the virtual lens in the duration of a shooting effect frame based on the comparison result.

The specific way of calculating the rotation angle corresponding to each display frame is as follows: taking the current display frame as an example, determining the display time difference between the current display frame and the previous display frame, and comparing the display time difference with the shooting effect calculation period to obtain a comparison result. The comparison aims at that if the display time difference is smaller than the shooting effect calculation period, the frame rate of the client is larger than 30 frames per second, which is equivalent to that a plurality of display frames exist in the original shooting effect calculation period; if the display time difference is equal to the shooting effect calculation period, the frame rate of the client is equal to 30 frames per second, which is equivalent to that only the first shooting effect frame exists in the original shooting effect calculation period; and if the display time difference is larger than the shooting effect calculation period, indicating that the client has a frame loss condition currently. For different comparison results, there are different determination ways to determine the rotation angle corresponding to the current display frame.

In some embodiments, the step of determining, based on the comparison result, a rotation angle corresponding to each display frame of the virtual lens within a duration of a shooting effect frame includes:

(1.1) if the comparison result shows that the display time difference is smaller than the shooting effect calculation period, calculating the ratio of the display time difference to the shooting effect calculation period to obtain a distribution ratio value;

(1.2) determining a rotation angle corresponding to the virtual lens in the current display frame according to the distribution ratio value;

(1.3) judging whether the current display frame is the last display frame in the shooting effect calculation period in which the current display frame is positioned;

and (1.4) if not, determining a next display frame of the current display frame as a current display frame, and when the current display frame is determined as a previous display frame, returning to the step of determining the display time difference between the current display frame and the previous display frame until the current display frame is the last display frame in the shooting effect calculation period in which the current display frame is located, so as to obtain the rotation angle of the virtual lens corresponding to each frame.

If the comparison result shows that the display time difference is smaller than the shooting effect calculation period, the frame rate of the client is larger than 30 frames per second, and a plurality of display frames exist in each shooting effect calculation period, so that the ratio of the display time difference to the shooting effect calculation period needs to be calculated to obtain the distribution ratio. Determining a rotation angle corresponding to the virtual lens in the current display frame according to the distribution proportion value; and after the rotation angle corresponding to the current display frame is obtained, judging whether the current display frame is the last display frame in the shooting effect calculation period, if not, indicating that residual display frames exist in the current shooting effect calculation period, determining the next display frame of the current display frame as the current display frame, and when the current display frame is determined as the previous display frame, circularly executing the step of determining the display time difference between the current display frame and the previous display frame until the current display frame is the last display frame in the shooting effect calculation period, so as to obtain the rotation angle corresponding to each frame of the virtual lens. And if the current display frame is the last display frame in the shooting effect calculation period, indicating that the rotation angle corresponding to each display frame in the shooting effect calculation period is determined completely, ending the current shooting effect calculation period, and continuously executing the process of calculating the rotation angle corresponding to each display frame in the next shooting effect calculation period.

In some embodiments, the step of determining a rotation angle of the virtual lens in the current display frame according to the allocation proportion value includes:

(1.1) acquiring a target total rotation angle corresponding to the shooting effect calculation period where the current display frame is located;

and (1.2) calculating the product of the distribution ratio value and the target total rotation angle to obtain the rotation angle of the virtual lens corresponding to the current display frame.

Because the current shooting effect calculation period has multiple frames of display frames, the rotation angle corresponding to the current display frame can be obtained according to the total rotation angle corresponding to the current shooting effect calculation period multiplied by the distribution ratio value of the current display frame in the shooting effect calculation period.

In some embodiments, the method further comprises:

(1.1) if the comparison result shows that the display time difference is equal to the shooting effect calculation period, acquiring a target total rotation angle corresponding to the shooting effect calculation period in which the current display frame is located;

and (1.2) calculating the product of a preset numerical value and the target total rotation angle to obtain the rotation angle corresponding to the virtual lens in the current display frame.

If the display time difference is equal to the shooting effect calculation period, the frame rate of the client is equal to 30 frames per second, which is equivalent to that only the first shooting effect frame exists in the original shooting effect calculation period, no other display frame exists, and the client displays one display frame and then walks through one shooting effect calculation period. The rotation angle corresponding to the current display frame is the product of the preset numerical value (1) and the target total rotation angle.

In some embodiments, the method further comprises:

(1) If the comparison result is that the display time difference is larger than the shooting effect calculation period, acquiring the current display frame sequence number and the previous display frame sequence number of the current display frame and the previous display frame in the shooting effect calculation period;

(2) Determining the number of display frames of the lost display frame based on the serial number of the previous display frame and the current display frame;

(3) Acquiring a rotation angle corresponding to the previous display frame, and calculating the product of the rotation angle corresponding to the previous display frame and the number of the display frames to obtain a first rotation angle;

(4) Determining a missing display frame one frame before the current display frame based on the current display frame sequence number;

(5) And determining a rotation angle corresponding to the virtual lens in the current display frame based on the lost display frame.

And if the comparison result shows that the display time difference is greater than the shooting effect calculation period, indicating that the client currently has a frame loss condition. And acquiring the serial number of the current display frame and the serial number of the previous display frame in the shooting effect calculation period of the current display frame and the previous display frame. For example: the shooting effect calculation period of the current display frame is 3 rd frame, and the previous display frame sequence number of the actually displayed previous display frame is 1 st frame. And determining the number of the display frames of the lost display frame, such as 1 frame which is the 2 nd frame, based on the serial number of the previous display frame and the current display frame. Because the rotation angle corresponding to the previous display frame is already calculated in the display process of the previous display frame, and the rotation angles of a plurality of display frames in a shooting effect calculation period are the same, the rotation angle corresponding to the previous display frame can be obtained, and the rotation angle of the previous display frame is multiplied by the number of the display frames of the lost display frame to obtain a first rotation angle at which the lost display frame should rotate, for example, the 2 nd frame is lost, the 1 st frame rotates by 2 °, and the 2 nd frame also rotates by 2 °.

Specifically, after the first rotation angle corresponding to the lost frame is calculated, the rotation angle that the current display frame should rotate needs to be calculated. Determining a lost display frame one frame before a current display frame according to a current display frame sequence number; and determining a rotation angle corresponding to the virtual lens in the current display frame based on the lost display frame.

In some embodiments, the step of determining a rotation angle corresponding to the virtual lens in the current display frame based on the lost display frame includes:

(1.1) determining a target initial rotation speed corresponding to the lost display frame based on the initial rotation speed and the rotation acceleration;

(1.2) determining a total rotation angle from a time point corresponding to the lost display frame to a next shooting effect calculation period according to the target initial rotation speed;

(1.3) calculating the ratio of the display time difference between the current display frame and the lost display frame to the shooting effect calculation period to obtain a target distribution ratio value;

(1.4) calculating the product of the target distribution proportion value and the total rotation angle to obtain a second rotation angle;

and (1.5) calculating the sum of the first rotating angle and the second rotating angle to obtain the rotating angle corresponding to the virtual lens in the current display frame.

The lost frame sequence number corresponding to the lost display frame is known, so that the target initial rotating speed corresponding to the lost display frame is determined based on the initial rotating speed and the rotating acceleration; determining a total rotation angle from a time point corresponding to the lost display frame to a next shooting effect calculation period according to the target initial rotation speed; calculating the ratio of the display time difference between the current display frame and the lost display frame to the shooting effect calculation period to obtain a target distribution ratio value; calculating the product of the target distribution ratio value and the total rotation angle to obtain a second rotation angle; and calculating the sum of the first rotating angle and the second rotating angle to obtain the rotating angle corresponding to the virtual lens in the current display frame.
