Detailed Description

The content of the invention will now be discussed with reference to a number of exemplary embodiments. It is to be understood that these examples are discussed only to enable those of ordinary skill in the art to better understand and thus implement the teachings of the present invention, and are not meant to imply any limitations on the scope of the invention.

As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" is to be read as "based, at least in part, on". The terms "one embodiment" and "an embodiment" are to be read as "at least one embodiment". The term "another embodiment" is to be read as "at least one other embodiment".

The position synchronization system comprises a client and a server, wherein the client can be a terminal device used by a player, such as an intelligent device with a game application function, such as a mobile phone, a computer, a tablet and the like, and is specifically used for acquiring an operation instruction of moving an object in a movable object bearing area, extracting a displacement parameter corresponding to the operation instruction, sending a position synchronization request of the object generated according to the displacement parameter to the server, and further receiving an absolute position coordinate of the object returned by the server. The server may be a server facility responsible for managing objects in the game, and within the server may be directed to subsystems that manage different objects, for example, there are subsystems responsible for managing player objects, there are subsystems responsible for managing monster objects, there are subsystems responsible for managing removable carrying objects, the server is mainly a subsystem responsible for managing the mobile bearing object, and is specifically used for receiving a position synchronization request of the object, respectively determining the absolute position coordinates of the movable bearing object and the relative position coordinates of the object in the movable bearing object area according to the displacement parameters carried by the position synchronization request of the object, and further, calculating the absolute position coordinates of the object according to the absolute position coordinates of the movable bearing object and the relative position coordinates of the object in the movable bearing object area, and transmitting the absolute position coordinates of the object to the client as broadcast information. In particular, in practical applications, the operation instruction of the object moving in the movable object bearing area is usually an operation instruction for controlling the object to move, and during the moving process of the object bearing, the movable object bearing may also move simultaneously, the absolute position coordinates of the object necessarily change, the server is used to store the relative position coordinates of the object in the movable object bearing area, so that each time the object moves, the client does not directly modify the absolute position coordinates of the object, but the server modifies the relative position coordinates of the object in the movable object bearing area, and then the absolute position coordinates of the object are calculated according to the absolute position coordinates of the movable object bearing and the relative position coordinates of the object in the movable object bearing area, the absolute position coordinates of the object taking into account the relative position coordinates of the object in the movable object bearing area, the absolute position coordinates of the object after the position of the object is changed can be accurately calculated, and the accuracy of object position synchronization is improved.

In order to solve the problem, the present embodiment provides a location synchronization method, as shown in fig. 1, which is applied to a client, and includes the following steps:

101. and acquiring an operation instruction of moving the object in the movable object bearing area, and extracting a displacement parameter corresponding to the operation instruction.

In a game scene, it is often necessary to create a large number of moving object models, for example, an object that a player enters into the game scene, a character object, a movable object, etc. that are set in the game scene, ideally, in a case where the object does not enter into a movable object area, absolute position coordinates of the object calculated after generating a control command for the moving object are determined only by a displacement parameter generated by the movement of the control object, and in a case where the object enters into the movable object area, the absolute position coordinates of the object calculated after generating a control command for the moving object need to consider the displacement parameter generated by the movement of the control object and the displacement parameter of the movable object during the movement. Therefore, the embodiment of the invention also adds the displacement parameter (if displacement exists) generated by the movement of the movable bearing object while considering the displacement parameter generated by the movement of the object.

In the embodiment of the present invention, the operation instruction for moving the movable object in the movable object bearing area may be a control instruction for triggering the object to move up, down, back, left, right, jump, launch skill, etc., and the control instruction for moving the movable object bearing may be a control instruction for triggering the movable object bearing to move up, down, left, right, rotate, etc. The displacement parameters corresponding to the specific operation instructions may set control parameters in multiple directions (including at least X, Y and even the Z coordinate direction) for any object in the game, and each direction control instruction corresponds to an offset attribute, which is a difference between a new coordinate and an original coordinate, and is equivalent to making a corresponding correction for the movement range of the object. Specifically, in the process of extracting the displacement parameter corresponding to the operation instruction, the control parameter of the object in the direction is obtained, so that the offset data of the object in the direction is extracted, and then the displacement parameter corresponding to the operation instruction is determined according to the offset attribute in the direction.

The execution main body of the embodiment may be a position synchronization device or equipment, and may be configured at the client, after the object model is constructed, because the object model generates a moving operation instruction in the movable object bearing region, the operation instruction corresponds to a displacement parameter, and a relative movement condition of the object in the movable object bearing region may be determined by the displacement parameter, so as to calculate an absolute position coordinate of the object according to the relative movement condition, and improve accuracy of object positioning.

102. And sending the position synchronization request of the object generated according to the displacement parameters to a server, and calculating the absolute position coordinate of the object by the server according to the relative position coordinate of the object in the movable object bearing area.

In the embodiment of the present invention, the displacement parameter may represent the movement of the object in different directions, and for the case that the object is not in the movable object-bearing area and moves, the position synchronization request of the object does not relate to the movement of the movable object-bearing area, and the client may modify the absolute position coordinate of the object directly based on the displacement parameter of the object; for the case that the object moves in the movable bearing object area, the position synchronization request of the object relates to the movement of the movable bearing object, the object can move while moving, if the client modifies the absolute position coordinate of the object directly based on the displacement parameter generating the movement, the absolute position coordinate of the object inevitably generates deviation, here, the position synchronization request generating the object by the displacement parameter generating the movement is sent to the server, and since the server stores the relative position coordinate of the object in the movable bearing area, the server can calculate the absolute position coordinate of the object based on the relative position coordinate and the absolute position coordinate of the movable bearing object.

Generally, an object enters a game scene and corresponds to an initial position coordinate, when the position of the object changes after moving, a client sends the position coordinate of the object after the position of the object changes to a server, the server performs necessary verification, and broadcasts the position coordinate of the object to clients of other players if the verification rule is satisfied, so that the position coordinate of the object can be correctly displayed in the clients of other players, if the position coordinate of the object has a large error, the object of one player can see the object of another player, and the object of the player can be attacked clearly when the skill is started is selected, the skill is not hit by the object of the player actually, or the object of one player can see the object of another player but cannot see the object of the player actually.

It should be noted that, here, the position coordinates of the object are absolute position coordinates of the object in the game scene, and any control command applied to the object is triggered based on the absolute position coordinates of the object.

103. Absolute position coordinates of the object are received.

In the embodiment of the invention, the absolute position coordinates of the object are calculated by the server, the client cannot acquire the server program and cannot modify the absolute position coordinates of the object in the program, and the game plug-in can be effectively prevented.

Further, as a refinement and an extension of the specific implementation of the foregoing embodiment, in order to fully describe the specific implementation process of the present embodiment, the present embodiment provides another position synchronization method, as shown in fig. 2, where the method includes:

201. when a trigger instruction that the object enters the movable object bearing area is detected, the initial position coordinates of the object are sent to the server side, and the server side calculates and stores the relative position coordinates of the object in the movable object bearing area.

In general, when an object does not enter the movable carrying object area, the absolute position coordinate of the modified object after the object moves is not affected by whether the movable carrying object moves, and when a trigger instruction that the object enters the movable carrying area is detected, the absolute position coordinate of the object and the absolute position coordinate of the movable carrying object have a relationship and are affected with each other.

202. And acquiring an operation instruction of moving the object in the movable object bearing area, and extracting a displacement parameter corresponding to the operation instruction.

It will be appreciated that the operating instructions for moving the object may be triggered by the player by clicking a mouse (or a touch screen action, etc.), and if the player wishes to move his object to a target location coordinate, the system may move the object to the target location coordinate by simply clicking the mouse at the target location coordinate, and if the target location coordinate is a building or inaccessible terrain, the system will reject the operating instructions for moving the object.

In the embodiment of the present invention, since the displacement parameter includes a displacement vector in a direction, and the direction of the object after each movement is a single direction, the displacement parameter of the object is a displacement value formed by the displacement vector in the direction, and the direction of the displacement value is the direction, for example, if the displacement vector is a control command for moving s in a direction of 90 degrees along the object coordinate system, the displacement value is s, and the direction is 90 degrees along the object coordinate system.

203. And sending the position synchronization request of the object generated according to the displacement parameters to a server, and calculating the absolute position coordinate of the object by the server according to the relative position coordinate of the object in the movable object bearing area.

In the embodiment of the invention, the position synchronization request of the object is a request sent by the client to the server for object relocation, after the object moves each time, the client can form the displacement parameter of the object into the position synchronization request of the object and send the position synchronization request of the object to the server, and the server carries out object relocation again, so that the absolute position coordinates of the object are consistent on the server and all the clients, the object position in the game scene is ensured to be correct, the game scene is truly restored, and the game experience of a user is improved.

204. Absolute position coordinates of the object are received.

In the related technology, the absolute position coordinates of the object are calculated on the client, the client program is easily stolen by a player, the player can modify the absolute position coordinates of the object after obtaining the client program to achieve the cheating function, the player cannot obtain the server program, the absolute position information of the object is calculated through the server, and the program modification cannot occur, so that the cheating by the player using the client program is effectively prevented.

205. And receiving the target position coordinates of the movable bearing object calculated according to the displacement parameters, and determining the absolute position coordinates of the movable bearing object.

It is understood that the movable bearing object is also an object with a movement function in a game scene, and can receive an operation instruction of movement. When a player controls the movable bearing object to move, the absolute position coordinate of the movable bearing object is necessarily changed, the absolute position coordinate of the object is also changed, but the relative position coordinate of the object in the movable bearing object area is not changed, the server calculates the target position coordinate of the movable bearing object based on the displacement parameter, the target position coordinate is the absolute position coordinate of the movable bearing object, and the target position coordinate is further sent to the client, so that the client can restore the real position of the movable bearing object in the world coordinate system by using the target position coordinate when rendering.

It should be noted that, the description of the position of any object in the game scene is usually absolute position coordinates of the object in a world coordinate system, where the absolute position coordinates can truly reflect the position of the object in the game scene, the world coordinate system is a reference framework required for describing other coordinate systems, and all objects in the three-dimensional world actually have their own object coordinate systems, for example, for an automobile object model, each vertex of the automobile object model should have its own position information, which is the position coordinates of the automobile object model in the object coordinate system, and when the automobile object model is put into the world coordinate system, the position where the origin of the automobile object model is located is the absolute position coordinates of the automobile object model in the world coordinate system.

206. And calculating the absolute position coordinates of the related objects in the movable bearing object area by using the absolute position coordinates of the movable bearing object.

For the situation that a player controls the movement of an object generated by a movable carrying object, because the movable carrying object is bound with related objects, such as various NPC objects, the NPC objects play an important role in a game scene as related objects, when the movable carrying object moves to a target position coordinate, the absolute position coordinate of the bound related objects also correspondingly moves, if the absolute position coordinates of a large number of related objects after moving are calculated by a server, the service resources are limited and the expression is delayed, the client can use hanging point information for the related objects to bind the related objects to the movable carrying object, and further when the target position coordinate formed by the movable carrying object on a displacement parameter is known, the absolute position coordinate of the movable carrying object is calculated, so that the rendering of the NPC objects on the client is accelerated, the player is not made to experience a disjointing between the NPC object and the movable carrying object.

It can be understood that the movable bearing object model and the associated object model belong to a parent-child relationship, the movable bearing object serves as a parent node, all associated object models bound to the movable bearing object belong to child nodes, and the hanging point information is used for associating the initial position relationship of the parent-child nodes. Specifically, the basic offset of the associated object relative to the movable bearing object can be determined by using the hanging point information of the associated object bound to the movable bearing object, the basic offset is further added to the absolute position coordinate of the movable bearing object, and the absolute position coordinate of the associated object in the movable bearing object area is calculated.

It should be noted that the above hanging point information can only ensure the correctness of the bound associated object as a child node relative to the initial offset position of the mobile bearer model as a parent node, however, if the associated object or the mobile bearer moves, the client needs to rely on the updated absolute position coordinates of the mobile bearer object to calculate the absolute position coordinates of the associated object.

In the embodiment of the present invention, each hanging point information may be provided with two hanging points, one hanging point is used to determine which part of the movable bearing object is bound to the associated object, and the other hanging point is used to determine which part of the associated object is bound to the movable bearing object, so that one hanging point corresponds to a coordinate system and can be represented by a matrix in the program. Specifically, in the process of determining the basic offset of the associated object relative to the movable bearer object by using the information of the hanging point at which the associated object is bound to the movable bearer object, the information of the hanging point at which the associated object is bound to the movable bearer object may be used to obtain the mutual binding position information of the associated object and the movable bearer object, the mutual binding position information may be determined by the two set hanging points, and further, the basic offset of the associated object relative to the movable bearer object may be determined according to the mutual binding position information of the associated object and the movable bearer object.

Specifically, in 3D mathematics, a matrix is an important tool for describing the relationship between two coordinate systems, an inflection point can be represented by the matrix in a program, and since the hanging point information includes not only position information in a three-dimensional space but also direction information in a three-dimensional attack, if the hanging point position is taken as an origin reference point, three direction components passing through the hanging point position as the origin reference point are taken as X, Y, Z axes, so that a physical coordinate system of the hanging point is formed.

For example, when an NPC object model needs to be bound to a gun platform in a warship model, two hanging point information need to be set, the first hanging point information is the hanging point information of the warship object model, and the hanging point is located at the gun platform at the bow of the warship object model, that is, the bound position information of the warship object model; the other hanging point information is the hanging point information of the NPC object model, the hanging point may be located at the head of the NPC object model, or may be the foot of the NPC object model, or may be any position of the NPC object model in the object coordinate system, it should be noted that if the hanging point is set on the foot of the NPC object model, the foot of the NPC object model is located at the position of the gunship object bow gun platform hanging point, and if the hanging point is set on the head of the NPC object, the head of the NCP object model is located at the position of the gunship object gunship bow gun platform hanging point.

Particularly, in an application scene that a battleship is used as a movable bearing object, the battleship is controlled by a player, the player can control the displacement of a battleship object through a direction key arranged above a UI interface, the initial position and the speed of the battleship object can be configured through an editor through planning, after the player object logs in the battleship, the player object can also move due to the displacement of the player controlled battleship, but the relative position coordinate of the object in the battleship object is not changed, a client can send the displacement parameters for controlling the displacement of the battleship object to a server, the server informs the current speed, the current direction and the movable target position of the battleship object of the client after legality verification, and the client can play animation after receiving the movable target position of the battleship object and the current speed and direction of the battleship object so that the battleship object can move to the target position coordinate, the target position coordinate is the absolute position coordinate of the warship, and further the absolute position coordinate of the associated object in the warship object can be calculated by utilizing the target position coordinate of the warship object.

In the embodiment of the invention, after the player presses the direction instruction key, only the direction information is sent to the server by the client, and since other information servers are known and cannot trust when the server receives any data of the client, the validity verification of the client, such as the position, the orientation and the like of the object model, is required to be carried out to prevent the player from cheating, so that the game experience of the player in a game scene is improved.

The embodiment provides another position synchronization method, as shown in fig. 3, which is applied to a server and includes the following steps:

301. receiving a position synchronization request of an object, and respectively determining the absolute position coordinate of the movable bearing object and the relative position coordinate of the object in the movable bearing object area according to the displacement parameter carried by the position synchronization request of the object.

Accordingly, for the movable carrying object, the server may set a subsystem responsible for managing the movable carrying object, specifically, a coordinate system may be established by using the subsystem with a central point of the movable carrying object as an origin, and the relative position coordinates of the object in the movable carrying object region may be modified according to the coordinate system.

It should be noted that the subsystem for managing the movable bearing object has various functions, which may specifically include, but is not limited to, the following:

(1) a player triggers an instruction on a movable bearing object control panel through a client, and the subsystem controls the movable bearing object according to the forward and backward turning of the instruction;

(2) a player triggers an instruction for a cannon in the movable bearing object through the client, and the subsystem controls the movable bearing object to cannon in the target direction according to the direction of the instruction;

(3) the player object can be revived in the movable bearing object after death, and in-situ revival and revival point revival are supported. For the in-place revival mode, the subsystem can record the relative position coordinates of the dead moment of the player object in the movable bearing object area, and the absolute position coordinates of the player object in the game world can be calculated through the relative position coordinates and the absolute position coordinates of the movable bearing object when the player object revives; for the revival point revival mode, the subsystem can set a plurality of revival point position coordinates in each movable carrying object region, the revival point position coordinates can be read when the player object revives, and the relative position coordinates of the player object in the movable carrying object region and the absolute position coordinates of the player object in the game world are calculated;

(4) the player triggers an instruction on the control panel of the movable bearing object through the client, the subsystem judges the direction of the instruction and the target position, and because the moving area of the movable bearing object is limited to the water surface area, if the player controls the movable bearing object to land, the movable bearing object stays on the land and cannot move to the target position.

(4) The player moves or releases skills in the movable carrying object area through the client, the subsystem can accurately calculate the absolute position coordinates of the player object according to the movement or release skills, and when the movable carrying object moves in one direction, the relative position coordinates of the player object in the movable carrying object area and the absolute position coordinates of the movable carrying object can be added to obtain the absolute position coordinates of the player object; when the movable carrying object turns, the player object needs to perform vector rotation around the central point of the movable carrying object according to the rotation angle of the movable carrying object to obtain the updated relative position coordinate of the player object, and the updated relative position coordinate and the absolute position coordinate of the movable carrying object are added to obtain the absolute position coordinate of the player object.

302. And calculating the absolute position coordinate of the object according to the absolute position coordinate of the movable bearing object and the relative position coordinate of the object in the movable bearing object area.

It is understood that, since the operation instruction for generating the object movement may be generated by the control object or the control movable bearing object, the following application scenarios may exist for the movement parameter including the displacement vector of different objects.

For an application scenario in the embodiment of the present invention, if the movement parameter only includes the displacement vector of the object, the absolute position coordinate of the movable bearing object is not changed, and the relative position coordinate of the object in the movable bearing object area is changed, specifically, the relative position coordinate of the object in the movable bearing object area may be adjusted based on the displacement vector of the object, and the absolute position coordinate of the object is further calculated according to the absolute position coordinate of the movable bearing object and the adjusted relative position coordinate of the object in the movable bearing object area.

For an application scenario in the embodiment of the present invention, if the movement parameter only includes the displacement vector of the movable carrying object, the absolute position coordinate of the movable carrying object changes, and the relative position coordinate of the object in the movable carrying object region does not change, specifically, the absolute position coordinate of the movable carrying object may be adjusted based on the displacement vector of the movable carrying object, and the absolute position coordinate of the object is further calculated according to the adjusted absolute position coordinate of the movable carrying object and the relative position coordinate of the object in the movable carrying object region.

For an application scenario in the embodiment of the present invention, if the movement parameter includes a displacement vector of the object and a displacement vector of the movable carrying object, the relative position coordinate of the object in the movable carrying object region changes, and the absolute position coordinate of the movable carrying object changes, specifically, the absolute position coordinate of the movable carrying object and the relative position coordinate of the object in the movable carrying object region may be respectively adjusted according to the displacement vector of the object and the displacement vector of the movable carrying object, and further, the absolute position coordinate of the object may be calculated according to the adjusted absolute position coordinate of the movable carrying object and the adjusted relative position coordinate of the object in the movable carrying object region.

For an application scenario in the embodiment of the present invention, if the displacement vector of the movable bearing object further includes a steering angle of the movable bearing object, before calculating the absolute position coordinate of the object according to the absolute position coordinate of the movable bearing object and the relative position coordinate of the object in the movable bearing object area, the object may be vector-rotated around the central point of the movable bearing object because the position of the object may be based on the steering angle of the movable bearing object, and the relative position coordinate of the object in the movable bearing object area is adjusted.

It should be noted that, the process of adjusting the relative position coordinates of the object in the movable object bearing area is mainly directed to the adjustment in the direction, and since the direction of the movable object bearing area changes during the turning process, the object in the movable object bearing area also needs the direction adjustment, so as to ensure the consistency of the directions of the objects in the movable object bearing area.

303. And transmitting the absolute position coordinates of the object to a client as broadcast information.
