Alternatively, the first avatar and the second avatar may belong to the same camp, the same team, the same organization, have a friend relationship, or have temporary communication rights. Alternatively, the first avatar and the second avatar may belong to different camps, different teams, different organizations, or have hostile relationships.

Alternatively, the clients installed on the first terminal 110 and the second terminal 130 are the same, or the clients installed on the two terminals are the same type of client on different operating system platforms (android or IOS). The first terminal 110 may refer broadly to one of the plurality of terminals and the second terminal 130 may refer broadly to another of the plurality of terminals, the present embodiment being illustrated with only the first terminal 110 and the second terminal 130. The device types of the first terminal 110 and the second terminal 130 are the same or different, and the device types include: at least one of a smart phone, a tablet computer, an electronic book reader, an MP3 player, an MP4 player, a laptop portable computer, and a desktop computer.

Only two terminals are shown in fig. 1, but in different embodiments there are a plurality of other terminals 140 that can access the server 120. Optionally, there are one or more terminals 140 corresponding to the developer, a development and editing platform for supporting the client of the virtual environment is installed on the terminal 140, the developer can edit and update the client on the terminal 140, and transmit the updated client installation package to the server 120 through a wired or wireless network, and the first terminal 110 and the second terminal 130 can download the client installation package from the server 120 to implement the update of the client.

The first terminal 110, the second terminal 130, and the other terminals 140 are connected to the server 120 through a wireless network or a wired network.

Server 120 includes at least one of a server, a plurality of servers, a cloud computing platform, and a virtualization center. The server 120 is used to provide background services for clients supporting a three-dimensional virtual environment. Optionally, the server 120 takes on primary computing work and the terminal takes on secondary computing work; alternatively, the server 120 takes on secondary computing work and the terminal takes on primary computing work; alternatively, a distributed computing architecture is used for collaborative computing between the server 120 and the terminals.

In one illustrative example, server 120 includes a processor 122, a user account database 123, an engagement service module 124, and a user-oriented Input/Output Interface (I/O Interface) 125. The processor 122 is configured to load instructions stored in the server 121, and process data in the user account database 123 and the combat service module 124; the user account database 123 is configured to store data of user accounts used by the first terminal 110, the second terminal 130, and the other terminals 140, such as an avatar of the user account, a nickname of the user account, and a combat index of the user account, where the user account is located; the combat service module 124 is configured to provide a plurality of combat rooms for users to combat, such as 1V1 combat, 3V3 combat, 5V5 combat, etc.; the user-oriented I/O interface 125 is used to establish communication exchanges of data with the first terminal 110 and/or the second terminal 130 via a wireless network or a wired network.

The server 120 may employ synchronization techniques to make the picture presentation uniform among multiple clients. Exemplary synchronization techniques employed by the server 120 include: state synchronization techniques or frame synchronization techniques.

State synchronization technique

In an alternative embodiment based on fig. 1, the server 120 employs a state synchronization technique to synchronize with multiple clients. In the state synchronization technique, as shown in fig. 2, combat logic operates in a server 120. When a state change occurs in a certain virtual object in the virtual environment, the server 120 transmits a state synchronization result to all clients, such as clients 1 to 10.

In an exemplary example, the client 1 transmits a request to the server 120 for requesting the virtual object 1 to release the frost skill, and the server 120 determines whether the frost skill is allowed to be released, and what the injury value to the other virtual object 2 is when the frost skill is allowed to be released. The server 120 then sends the skill release results to all clients, which update the local data and interface presentation based on the skill release results.

Frame synchronization technique

In an alternative embodiment based on fig. 1, the server 120 employs a frame synchronization technique to synchronize with multiple clients. In the frame synchronization technique, as shown in fig. 3, combat logic operates in each client. Each client sends a frame synchronization request to the server, where the frame synchronization request carries the local data changes of the client. After receiving a certain frame synchronization request, the server 120 forwards the frame synchronization request to all clients. After each client receives the frame synchronization request, the frame synchronization request is processed according to local combat logic, and local data and interface performances are updated.

In connection with the description of the virtual environment and the description of the implementation environment, the method for displaying the virtual environment picture provided in the embodiment of the present application is described, and the execution body of the method is exemplified as a client running on the terminal shown in fig. 1. The terminal is operated with a client, which is an application supporting a virtual environment.

Referring to fig. 4 in combination, during a virtual environment based athletic procedure, a user interface is displayed on the client. An exemplary user interface includes: a virtual environment screen 22 and a HUD (Head Up Display) panel 24. The virtual environment screen 22 is a screen obtained by observing the virtual environment using the angle of view corresponding to the virtual object 26. The HUD panel 24 includes a plurality of human-machine interaction controls, such as a move control, three or four skill release controls, and attack buttons, among others.

Illustratively, each virtual object has a one-to-one correspondence of camera models in the virtual environment. The virtual object 26 in fig. 4 corresponds to a camera model 28. The center of view (or focus) of the camera model 28 is the virtual object 26, and the center of view is the intersection of the virtual environment and the center line of view of the camera model 28 along the direction of view, also referred to as the focus of the camera model 28. The object located in the observation center is located in the center of the virtual environment screen acquired by the camera model 28. As the virtual object 26 moves within the virtual environment, the three-dimensional coordinates (also referred to as anchor points) of the camera model 28 within the virtual environment also move following the movement of the virtual object 26. The camera model 28 has a lens height relative to the virtual object 26. The camera model 28 looks down at the virtual object 26 at an oblique angle (e.g., 45 degrees).

The frames captured by the camera model 28 in the virtual environment are the virtual environment frames 22 displayed on the client.

The embodiment of the application provides a scheme for dynamically changing the anchor point of the camera model 28, so that the visual field of the virtual environment picture 22 is dynamically changed, and the method and the device more meet the expectations of users.

In the example shown in fig. 5, the terminal displays a user interface including a virtual environment screen and a human-machine interaction control superimposed on the virtual environment screen. The man-machine interaction control comprises: a field of view adjustment control 32, a direction of movement control 34, a skill release control 36, and an attack control 38, as shown in fig. 5 (a). By default, the virtual environment frame is a frame acquired in the virtual environment by the camera model 28 with the first location where the virtual object 26 is located as the viewing center. When the user wishes to change the field of view, the field of view adjustment control 32 is pressed. The field of view adjustment control 32 changes from a smaller eye display configuration to a larger wheel display configuration, as shown in fig. 5 (b). In the wheel display configuration, the field of view adjustment control 32 includes a wheel region and a rocker located at the center of the wheel region. Wherein the rocker corresponds to an anchor position of the camera model 28 and the wheel area corresponds to an adjustable range of anchor positions of the camera model 28. Illustratively, the adjustable range is a circular range.

Illustratively, as the user drags the rocker to change position in the wheel area, the anchor point of the camera model 28 in the virtual environment will also change. After changing the anchor point position, the viewing center of the camera model 28 will switch from a first position where the virtual object 26 is located to a second position where there is an offset with respect to the virtual object 26. The positional relationship of the second position with respect to the first position corresponds to the positional relationship of the rocker with respect to the center position of the wheel disc area, as shown in fig. 5 (c).

When the user's finger is released, the camera model 28 will capture a picture in the virtual environment as a viewing center at a second position offset from the virtual object 26, as shown in fig. 5 (d). Since the location of the virtual environment 26 may change at all times, the second location, at which there is an offset relative to the virtual object 26, also changes at all times.

The operation of the whole process may include the steps of:

clicking a rocker:

the user clicks the rocker on the view adjustment control and when the user's finger is pressed, the anchor point position of the camera model returns to the default position. The default position is the anchor point position when the user-controlled first virtual object is at the center of the screen.

Dragging the rocker:

1. when the user drags the rocker on the view adjustment control, the anchor point position of the camera model will shift from the default position. After the user's finger is lifted, the anchor point position of the camera model stays at the last offset position.

2. What the user drags the rocker changes is the relative position of the anchor point position of the camera model and the first virtual object, i.e. the anchor point position of the camera model is bound to the first virtual object. When the first virtual object moves, the anchor point position of the camera model also moves.

Fig. 6 is a flowchart illustrating a method for displaying a virtual environment screen according to an exemplary embodiment of the present application. The embodiment is exemplified by the method applied to the client. The method comprises the following steps:

step 602, displaying a first virtual environment screen, wherein the first virtual environment screen is obtained by observing the virtual environment with a first position relative to a first virtual object as an observation center;

the first virtual object is a virtual object controlled by a client, but the possibility that the first virtual object is controlled by other clients or artificial intelligence modules is not excluded. The client controls the activities of the first virtual object in the virtual environment according to the received user operation (or man-machine operation). Illustratively, the activity of the first virtual object in the virtual environment includes: at least one of walking, running, jumping, climbing, lying down, attacking, releasing skills, picking up props, and sending messages.

The first virtual environment screen is a screen obtained by observing the virtual environment by the camera model with the first position relative to the first virtual object as an observation center. Optionally, the camera model also has a lens height with respect to the first virtual object. The virtual environment picture is a two-dimensional picture displayed on the client after the picture collection of the three-dimensional virtual environment. The shape of the virtual environment screen is illustratively determined according to the shape of the display screen of the terminal or according to the shape of the user interface of the client. Taking the example that the display screen of the terminal is rectangular, the virtual environment screen is also displayed as a rectangular screen.

A camera model bound with the first virtual object is arranged in the virtual environment. The first virtual environment screen is a screen captured by the camera model with a certain observation position in the virtual environment as an observation center. When the first virtual environment picture is acquired, the observation center is a first position relative to the first virtual object. For example, the first location is where the first virtual object is located. Taking the example that the first virtual environment picture is a rectangular picture, the intersection point of the diagonal lines of the rectangle in the first virtual environment picture is the object positioned in the observation center.

In general, the camera model bound to the first virtual object takes the position of the first virtual object as an observation center, and the position of the first virtual object in the virtual environment is the first position. When the virtual environment is a three-dimensional virtual environment, the observation center is the three-dimensional coordinates of the first virtual object in the virtual environment. For example, if the ground in the virtual environment is a horizontal plane, the height coordinate of the observation center is 0, and the observation center may be approximately expressed as a two-dimensional coordinate on the horizontal plane.

Step 604, in response to an adjustment instruction of the observation center, adjusting the observation center from a first position relative to the first virtual object to a second position relative to the first virtual object;

the adjustment instruction is an instruction for adjusting the observation center. The adjustment instruction is triggered by the user, but does not exclude the possibility that the adjustment instruction is triggered automatically by artificial intelligence (Artificial Intelligence, AI) in the terminal, or sent by the server.

When the terminal is an electronic device with a touch screen, the adjustment instruction may be an instruction triggered by a touch operation on the touch screen; when the terminal is an electronic device with a handle peripheral, the adjustment instruction may be an instruction triggered on a physical key of the handle; when the terminal is VR or AR, the adjustment instruction may be an instruction triggered by an eye or voice of the user, and the triggering manner of the adjustment instruction in the embodiment of the present application is not limited.

The first location is, for example, a location where the first virtual object is located, or the first location is a location where there is a first offset relative to the location where the first virtual object is located.

The second location is, for example, a location at which there is a second offset relative to the location at which the first virtual object is located. Typically, the first and second positions are different.

Since the position of the first virtual object is dynamically changed, the second position relative to the first virtual object is also changed following the change in the position of the first virtual object.

Step 606, displaying a second virtual environment screen, wherein the second virtual environment screen is obtained by observing the virtual environment with a second position relative to the first virtual object as an observation center;

since the observation centers of the first virtual environment screen and the second virtual environment screen are different, the fields of view of the first virtual environment screen and the second virtual environment screen are different.

As schematically shown in fig. 7, in the first virtual environment screen, the center of the screen is a first position 72 relative to the first virtual object, where the first position 72 is the position where the first virtual object is located, and the first virtual object is located in the center of the screen; in the second virtual environment screen, the screen center is the second position 74 relative to the first virtual object, and the second position 74 is a position having a second offset in the upper right direction relative to the first virtual object, and at this time, the first virtual object is positioned at the lower left corner of the screen center, and the user's upper right field of view of the first virtual object is increased and the lower left field of view is decreased.

In summary, in the method provided in this embodiment, by modifying the observation center from the first position relative to the first virtual object to the second position in response to the adjustment instruction of the observation center, the user may customize the observation center of the camera model, thereby obtaining an optimal field of view that satisfies the user's own expectations, and displaying more effective information in the virtual environment image as much as possible.

The adjustment instruction may be triggered by a drag operation by a user on a view adjustment control displayed on the touch display screen.

Fig. 8 is a flowchart illustrating a method for displaying a virtual environment screen according to another exemplary embodiment of the present application. The method may be performed by the client shown in fig. 1. The method comprises the following steps:

step 802, displaying a first user interface, wherein the first user interface comprises a first virtual environment picture and a visual field adjustment control, and the first virtual environment picture is obtained by observing a virtual environment by taking a first position relative to a first virtual object as an observation center;

the client displays a first user interface, the first user interface comprising: a first virtual environment screen 90 acquired by the camera model, and a view adjustment control 32 superimposed on the first virtual environment screen.

A camera model bound with the first virtual object is arranged in the virtual environment. The first virtual environment picture takes the position of the first virtual object as an observation center in the camera model, and the position of the first virtual object in the virtual environment is the first position.

Illustratively, when the virtual environment is a three-dimensional virtual environment, the observation center is a three-dimensional coordinate of the first virtual object in the virtual environment. For example, if the ground in the virtual environment is a horizontal plane, the height coordinate of the observation center is 0, and the observation center may be approximately expressed as a two-dimensional coordinate on the horizontal plane.

Optionally, the view adjustment control 32 includes: wheel disc area a and rocker b. The wheel area a is a circular area and the rocker b is a circular button. The area of the rocker b is smaller than the area of the wheel disc area a. In the case where the drag operation of the user is not received, the jog b is displayed at the center of the wheel area a. Upon receiving a drag operation by the user, the rocker b may change position within the circular area of the wheel area a.

The rocker b corresponds to an observation center of the camera model (i.e., an anchor point position of the camera model), the wheel disc area a corresponds to a default observation center of the camera model, for example, a position of the first virtual object is located, and a circular area range of the wheel disc area a corresponds to an adjustable range of the observation center of the camera model.

Step 804, responding to a dragging instruction triggered when the rocker is dragged in the wheel disc area, and adjusting the observation center from a first position relative to the first virtual object to a second position relative to the first virtual object according to the position of the dragged rocker in the wheel disc area;

since the wheel disc region a corresponds to the default viewing center of the camera model, the circular region range of the wheel disc region a corresponds to the adjustable range of the viewing center of the camera model. Therefore, after the client receives the drag operation of the user, in response to a drag instruction triggered when the rocker is dragged in the wheel area, the observation center is adjusted from a first position relative to the first virtual object to a second position relative to the first virtual object according to the position of the dragged rocker in the wheel area. Specifically, the steps S1 to S5 are as follows, as shown in fig. 9:

s1, responding to a dragging instruction triggered when a rocker is dragged in a wheel disc area, and calculating a wheel disc transverse offset value and a wheel disc longitudinal offset value of the position of the dragged rocker in the wheel disc area relative to the central position of the wheel disc area;

referring to fig. 10, assuming that the position of the dragged rocker in the wheel disc area is P2 and the center position of the wheel disc area is P1, the wheel disc lateral offset value is the projected length (P2-P1) x of (P2-P1) in the horizontal direction and the wheel disc longitudinal offset value is the projected length (P2-P1) z of (P2-P1) in the vertical direction.

Wherein the wheel lateral offset value and the wheel longitudinal offset value are two-dimensional offsets on the UI layer, and the camera model is in a three-dimensional virtual environment, requiring mapping of the two-dimensional offsets to three-dimensional offsets.

Referring to fig. 10, an x-axis, a y-axis, and a z-axis are provided in the three-dimensional virtual environment. Wherein the y-axis corresponds to the lens height of the camera model. In this embodiment, the wheel lateral offset value is set to correspond to the offset value of the camera model in the x-axis, and the wheel longitudinal offset value corresponds to the offset value of the camera model in the z-axis, both of which do not affect the position of the camera model in the y-axis. That is, the lens height of the camera model is a fixed value or otherwise adjusted, but is independent of the adjustment logic in this embodiment.

S2, determining a first camera offset value according to the wheel disc transverse offset value, and determining a second camera offset value according to the wheel disc longitudinal offset value;

the first camera offset value is an offset value of the camera model in the x-axis and the second camera offset value is an offset value of the camera model in the z-axis. The X-axis and the z-axis are two coordinate axes parallel to the ground plane in the virtual environment, and the X-axis is perpendicular to the z-axis.

Optionally, the wheel disc lateral offset distance and the first camera offset value are in positive correlation; the wheel disc longitudinal offset distance and the second camera offset value are in positive correlation. For example, the wheel disc lateral offset distance and the first camera offset value are in a proportional relationship; the wheel longitudinal offset distance and the second camera offset value are in a proportional relationship.

S3, calculating a first anchor point position of a camera model corresponding to the first virtual object by taking the position of the first virtual object in the virtual environment as a reference;

the first anchor point location moves following the movement of the location of the first virtual object.

Optionally, the first anchor point position is a three-dimensional coordinate of the camera model in the virtual environment when the observation center of the camera model is the first virtual object.

S4, shifting the first anchor point position according to the first camera shift value and the second camera shift value, and calculating to obtain a second anchor point position of the camera model;

and shifting the first anchor point position on the x-axis according to the first camera offset value, shifting the first anchor point position on the z-axis according to the second camera offset value, and calculating to obtain the second anchor point position of the camera model.

And S5, offsetting the camera model according to the second anchor point position, wherein the observation center of the offset camera model is a second position relative to the first virtual object.

And S6, responding to the change of the position of the first virtual object in the virtual environment, and executing the step of shifting the first anchor point position according to the first camera shift value and the second camera shift value again, and calculating to obtain the second anchor point position of the camera model.

Since the first virtual object can be moved in the three-dimensional virtual environment, when the position of the first virtual object in the three-dimensional virtual environment changes, the client performs the step of calculating a second position relative to the first virtual object according to the offset direction and the second offset distance based on the position of the first virtual object in the virtual environment.

The viewing center of the camera model (relative to the second position of the first virtual object) will still dynamically change following the position of the first virtual object.

Before the current adjustment is finished and the next adjustment (manual or automatic adjustment is started), the observation center of the camera model is kept at the second position, that is, the camera model continuously performs picture acquisition according to the second position relative to the first virtual object as the observation center.

Step 806, displaying a second user interface, where the second user interface includes a second virtual environment screen and a field of view adjustment control, where the second virtual environment screen is a screen obtained by observing the virtual environment with a second position relative to the first virtual object as an observation center;

and after the observation center is adjusted to be a second position, the camera model observes the virtual environment by taking the second position relative to the first virtual object as the observation center, and a second virtual environment picture is obtained. The client also superimposes and displays a view adjustment control on the second virtual environment picture, thereby displaying a second user interface.

Optionally, if the view adjustment control is opaque, the blocked area in the second virtual environment screen does not need to be displayed; and if the visual field adjusting control is transparent or semitransparent, overlapping the blocked area in the second virtual environment picture and the visual field adjusting control into a fusion image for displaying.

In summary, according to the method provided by the embodiment, the offset information of the camera model in the three-dimensional environment is calculated by adopting the wheel disc offset information of the rocker on the two-dimensional plane, so that the rocker change of the visual field adjustment control and the three-dimensional offset of the camera model are in positive correlation, and the operation effect of 'what you see is what you get' is achieved.

In an alternative embodiment based on fig. 8, the drag instruction includes: at least two sub-instructions ordered in time. Typical drag instructions include: and a touch start sub-instruction, a plurality of touch movement sub-instructions and a touch end sub-instruction which are sequenced according to time, wherein each sub-instruction carries real-time touch coordinates of a user on the touch screen. The touch start sub-instruction may be considered the first sub-instruction, and the touch end sub-instruction may be considered the last sub-instruction. As shown in fig. 11, the method further includes:

Step 803a, in response to receiving a first sub-command in the drag command, switching the view adjustment control from a default display mode to a wheel disc display mode, wherein the wheel disc display mode comprises a rocker and a wheel disc region;

the display area of the default display mode is smaller than that of the wheel disc display mode.

Alternatively, the default display form is a smaller eye button. The smaller eye buttons do not obscure too much of the screen content on the second virtual environment screen.

In step 805, in response to receiving the last sub-instruction in the drag instruction, the view adjustment control is switched from the wheel display form to the default display form.

In summary, according to the method provided by the embodiment, by providing two display modes for the visual field adjustment control, the visual field adjustment control in the default display mode has a smaller display area, so that the influence on the picture content in the virtual environment picture can be reduced.

In an alternative embodiment based on fig. 8, the viewing center of the camera model may be adjusted multiple times as the user is engaged in a single game in order to ensure operational consistency of each adjustment process. As shown in fig. 12, the method further includes:

In step 803b, in response to receiving the first sub-instruction in the drag instruction, the observation center is reset to the location of the first virtual object in the virtual environment.

When the client receives a drag operation on the visual field adjustment control, the client triggers a drag instruction on the visual field adjustment control. The drag instruction includes: and according to the time-ordered touch start sub-instruction, a plurality of touch movement sub-instructions and a touch end sub-instruction, wherein each sub-instruction carries real-time touch coordinates of a user on the touch screen.

In response to receiving the touch start sub-instruction, the client resets the observation center to the location of the first virtual object in the virtual environment. That is, the client resets the coordinates of the camera model in the virtual environment to the first anchor point location.

In summary, the method provided in this embodiment resets the observation center to the position where the first virtual object is located in the virtual environment when the drag instruction on the visual field adjustment control is received, so that the user can obtain a consistent operation feeling when adjusting the observation center each time, and thus the observation center can be quickly and accurately adjusted to the desired position.

In an alternative embodiment, the adjustment range of the viewing center of the camera model is limited.

As shown in fig. 13, the client sets maximum offset values of the observation center of the camera model in four directions of up, down, left, and right: UP, DOWN, LEFT, RIGHT. UP is the maximum offset value in the upper direction, DOWN is the maximum offset value in the lower direction, LEFT is the maximum offset value in the LEFT direction, and RIGHT is the maximum offset value in the RIGHT direction.

When the visual field adjustment control is implemented by adopting a wheel disc control, the wheel disc control comprises: a wheel area and a rocker located on the wheel area. The position of the rocker over the wheel area (offset position relative to the wheel center) corresponds to the viewing center of the camera model (offset position relative to the first virtual object). The circular area extent of the wheel disc area corresponds to the maximum adjustable extent of the viewing center. Each position on the wheel area is "one-to-one" with respect to the maximum adjustable range of the viewing center in the virtual environment.

In an alternative embodiment, the anchor point position of the camera model is calculated as follows:

as shown in fig. 14, the angle between the rocker and the horizontal direction is α, the distance between the rocker and the circle of the wheel disc area is a, and the radius of the circle of the wheel disc area is B. If the rocker is offset to the upper left, the anchor point position of the camera model is also offset to the upper left from the default anchor point position by the same angle.

LEFT offset of camera model = cos α LEFT (a/B);

upward offset of camera model = sin α UP (a/B).

In an alternative embodiment, three variables are first defined as follows:

cameliaoffset: the offset value of the observation center of the camera model relative to the first virtual object is measured. The control module of the camera model reads the value, and adds the offset value to the logic of the camera model following the first virtual object, thereby achieving the function of offset of the observation center of the camera model.

IsMoved: to distinguish whether a user's operation on the joystick is a click operation or a drag operation. When the user presses the rocker button, it is set to no (false); when the dragging distance of the user to the rocker exceeds the dead zone area, the dragging distance is set to true.

Loadzone (dead zone): configured by the plan, a threshold value for distinguishing whether a touch operation on a rocker is a click operation or a drag distance of a drag operation in a wheel area is schematically shown in fig. 15, and an edge of a dead zone is shown as a dotted circle 40.

As shown in fig. 16, the method for displaying a virtual environment screen includes the steps of:

step 1601, a rocker of the field of view adjustment control is pressed;

The user presses the rocker of the field of view adjustment control, triggering the generation of a touch start event on the touch screen. The touch start sub-event carries the two-dimensional coordinates of the user's pressed location on the touch screen.

Step 1602, resetting the offset value of the camera model to zero;

the client resets the offset value CameraOffset of the camera model to zero. This clears the offset value of the last camera model.

Step 1603, ismoved=false;

the client sets the value of IsMoved to false.

Step 1604, the rocker of the field of view adjustment control is dragged;

the user drags the rocker of the visual field adjusting control, and a touch movement event is continuously triggered (according to the reporting frequency of the touch) on the touch screen. Each touch movement event carries two-dimensional coordinates of the user's touch location on the touch screen.

Step 1605, assigning the position of the dragged rocker to P2;

and the client assigns the two-dimensional coordinate of the dragged rocker on the touch screen as P2.

Step 1606, determine if |p2-p1| is greater than or equal to the dead zone radius, and ismoved= =true;

p1 is the two-dimensional coordinate of the center point of the wheel area on the touch screen.

In the process of dragging the rocker by a user, the client judges whether the displacement |P2-P1| of the dragged rocker position relative to the center point of the wheel disc area reaches a dead zone threshold value or not. I.e., whether |P2-P1| is greater than or equal to deadZone.

If the dragging distance reaches the dead zone threshold, then step 1607 is performed; if the drag distance does not reach the dead zone threshold, then IsMoved=true is maintained.

Step 1607, ismoved=true;

the client sets the value of IsMoved to true.

In step 1608, an offset value of the camera model is calculated as a vector (P2-P1).

Firstly, the client reads five preset values:

LEFT: maximum offset value in the left direction;

RIGHT: maximum offset value in the right direction;

DOWN: maximum offset value in the lower direction;

UP: maximum offset value in the upper direction;

max_radius: maximum drag distance of the rocker in the wheel area.

Because at the User Interface (UI) layer is a two-dimensional plane, (P2-P1) is a two-dimensional vector, and the anchor point position of the camera model is in a three-dimensional scene, the offset vector of the camera model is a three-dimensional vector. Assuming that the lens height of the camera model is kept unchanged, it is necessary to fix the y-coordinate offset component (coordinate component corresponding to the lens height) in the anchor point position of the camera model by 0, and then calculate the lens offset with the following steps:

1. the length of (P2-P1) is calculated as length,

2. the formula for calculating the offset value cameraoffset. X of the camera model in the x-axis (horizontal direction) is as follows

If (p 2-p 1). X >0, the representation is offset to the right;

cameraOffset.x＝(p2-p1).x/MAX_RADIUS*RIGHT；

other cases, represent a left shift;

cameraOffset.x＝(p2-p1).x/MAX_RADIUS*LEFT。

3. the formula for calculating the offset value cameraoffset. Z of the camera model in the z-axis (horizontal direction) is as follows:

if (p 2-p 1). Z >0, the representation is offset upward;

cameraOffset.z＝(p2-p1).y/MAX_RADIUS*UP；

other cases, represent a left shift;

cameraOffset.z＝(p2-p1).y/MAX_RADIUS*DOWN。

referring to fig. 16 in combination, it can be seen that the client typically configures a height to be the height distance between the first virtual object actor and the camera model, and configures an inclination angel to be the angle at which the camera model looks downward. And then the client calculates a default anchor point position of the camera model through the current position of the first virtual object. Since the camera does not change relative to the x-axis of the first virtual character due to the game setting, only the y-and z-axes need to be changed, the calculation formula of the camera model in the virtual environment (following the first virtual object) is as follows:

cameraPos.x＝ActorPos.x；

cameraPos.y＝ActorPos.y+height*cos(angle)；

camearPos.z＝ActorPos.z–height*san(angle)；

after the default anchor point position of the camera model is calculated, adding the calculated offset value (camera offset. X, camera offset. Z) to the camera model to obtain the final anchor point position of the camera model, and also achieving the lens offset effect on the camera model.

cameraPos＝cameraPos+cameraOffset。

The arrangement of the x-axis, the y-axis and the z-axis in the three-dimensional virtual environment is shown in fig. 4.
