Description
Technical Field
The invention relates to the field of virtual games, in particular to a method and a device for acquiring position coordinates of a virtual game object, electronic equipment and a computer readable medium.
Background
With the development of game technology, the variety of games is more and more diversified. The vehicle is used as an auxiliary device for movement and fighting, and becomes a setting play method which is inevitably existed in most games. The player can get some additional game experience by using the carrier, and the following are common settings: 1. improving some attributes of the passenger carrier, such as moving speed; 2. obtaining additional capacity by operating the vehicle, such as the vehicle can be operated to attack, or the defense capacity is improved; 3. switching different game areas by taking the carrier, such as taking a flying carrier off the ground; 4. the collecting and displaying carrier can well meet the collecting desire and the personalized requirements of the player. The existence of the carrier greatly enriches the game modes of the players and is an important element in various games in recent years. With the continuous expansion and enrichment of playing methods, the functional requirements on the carrier are higher and higher. The basic function of the carrier is to carry players to move, but when the carrier is set to be a large carrier capable of carrying a plurality of players, the existing carrier processing method is difficult to accurately and truly reflect that a plurality of players and other game elements move along with the carrier, and is further difficult to process complex playing methods such as battles, interactions and the like of the game elements on the carrier.
The existing carrier processing method is more biased to the single carrier performance or the performance of complex game contents without moving or fighting. In order to simplify the process, the existing carrier processing method treats the carrier and the riding object as a whole, cannot truly reflect the relative relationship between the carrier and the riding object, limits the setting of the playing method based on the carrier in the aspects of carrying quantity, moving, fighting, path finding, animation expression and the like, and greatly influences the game experience of a player in the use of the carrier. Because the relative relation between the carrier and the riding object is ignored in the existing carrier processing method, the existing carrier processing method usually adopts the action of a prefabricated fixed model to perform overall expression, the independence of the carrier and the riding object cannot be flexibly and really embodied, and the influence of the action change of one party on the other party cannot be expressed in real time.

The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.
FIG. 1 is a flow chart illustrating a method of obtaining position coordinates of a virtual gaming object, according to an exemplary embodiment.
As shown in fig. 1, in S102, a game scene and at least one vehicle are generated by rendering, and the vehicle can mount a virtual game object in a virtual game. In the embodiment of the invention, the game scene and the vehicles are generated through rendering, and a plurality of vehicles can be contained in the same game scene. The vehicle is a moving and fighting auxiliary device in the virtual game, and most of the virtual games have set playing methods, and a player can obtain some additional game experience by using the vehicle.
In S104, a first type coordinate system is assigned to the game scene. For the rendered game scene, a coordinate system is assigned, which may be, for example, a first type coordinate system, and for a game scene, the first type coordinate system may be used as a base coordinate system, i.e., an absolute coordinate system. An absolute coordinate system is a coordinate system where all coordinates are based on a description of the location of a fixed coordinate system origin. An absolute coordinate is a fixed coordinate position with which the coordinates of the point input do not differ from one reference object to another.
In S106, a second type coordinate system is respectively assigned to each of the at least one vehicle. The vehicles in the game scene are respectively assigned with a second type coordinate system, which may be a relative coordinate system, for example, and the coordinate systems are divided into an absolute coordinate system and a relative coordinate system according to the difference of the reference values. Relative coordinate system means relative to an absolute coordinate system, relative coordinate system referring to a coordinate system relative to the coordinate position of a previous point. If a plurality of vehicles exist in the scene, a second type coordinate system (relative coordinate) is respectively allocated to the plurality of vehicles. Due to the different positions of the multiple vehicles in the scene, the assigned relative coordinate systems are also different. For example, if there are vehicles on a vehicle, the coordinate system of the vehicle above the vehicle may be the relative coordinate system of the vehicle below the vehicle close to the spatial position. Based on the spatial position relationship between the vehicles, a hierarchical structure of relative coordinate systems can be generated, for example. The invention is not limited thereto.
In S108, the second type of coordinates of the virtual game object in the current carrier is obtained in real time, where the second type of coordinates is the coordinates of the virtual game object in the second type of coordinate system of the current carrier. When the virtual game object is positioned in the carrier, the coordinate system corresponding to the carrier is used for distributing the coordinate to the virtual game object. For example, when the virtual game object is located in a plurality of vehicles, different coordinates may be respectively allocated to the virtual game object according to different second coordinate systems corresponding to the plurality of vehicles.
In S110, a first type of coordinate of the vehicle currently carried by the virtual game object is obtained in real time, where the first type of coordinate is a coordinate of the vehicle currently carried by the virtual game object in a first type of coordinate system. The coordinates of the virtual game object in the current scene may be obtained in real time, for example.
In S112, the first type coordinates of the virtual game object are calculated according to the second type coordinates of the virtual game object on the current carrier obtained in real time and the first type coordinates of the virtual game object on the current carrier.
According to the method for acquiring the position coordinates of the virtual game object, the movement and the fighting expression of the riding object on the carriers, among the carriers and between the carriers and the scene are realized through the mutual conversion among different coordinate systems.
It should be clearly understood that the present disclosure describes how to make and use particular examples, but the principles of the present disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
In an exemplary embodiment of the present disclosure, the virtual game object operates according to the first type coordinate system when located in the scene; and when the virtual game object is positioned on any carrier of the at least one carrier, operating according to a second type coordinate system corresponding to the any carrier. For example, a virtual game object operates according to first-class coordinates, i.e., absolute coordinates, when located in a scene; and when the virtual game object is positioned in the carrier, operating according to the second type of coordinate, namely the relative coordinate. In a conventional carrier system, a carrier and a riding object are generally taken as a whole, and only one coordinate system is used for recording the positions of the carrier and the riding object, so that the movement of the riding object on the carrier cannot be shown, and a game playing method that multiple riding objects move independently on the carrier or even fight against each other cannot be realized. In the embodiment of the present invention, the movement of the virtual game object on the carrier is marked by the second type of coordinates, which may, for example, consider the movement of the virtual game object as relative motion with respect to absolute coordinates, and may, for example, convert the second type of coordinates into the first type of coordinates, so that when the virtual game object performs movement and battle calculation, the coordinate system of the object is converted from the node of the operation level (usually, the scene level) to the node of the corresponding carrier level, thereby realizing that the riding object performs correct movement and battle performance on any level of the carrier.
According to the method for acquiring the position coordinates of the virtual game object, the absolute coordinates and the relative coordinates are respectively distributed to the game scene and the carriers in the scene, and the virtual game object is marked in the carriers through the relative coordinates, so that the virtual game object can be correctly moved and battle expressed on any carrier when the virtual game object is carried on the virtual carrier, and the game experience is greatly enriched.
In an exemplary embodiment of the present disclosure, the at least one vehicle may include a plurality of vehicles, the lower vehicle may carry an upper vehicle, and when the vehicle currently carried by the virtual game object is used as the upper vehicle to carry the lower vehicle, the first type of coordinates of the vehicle currently carried by the virtual game object is obtained in real time, which specifically includes: acquiring a second type of coordinates of a lower carrier taken by a current carrier taken by the virtual game object in real time; acquiring a first type of coordinate of a lower carrier in real time; and calculating the first type of coordinates of the carrier currently carried by the virtual game object according to the second type of coordinates of the carrier currently carried by the virtual game object in real time and the first type of coordinates of the carrier at the lower layer.
Fig. 2 and 3 are schematic diagrams illustrating a method of acquiring position coordinates of a virtual game object according to another exemplary embodiment.
As shown in fig. 2 and 3, a coordinate system of the ride object, which may be, for example, a multi-level coordinate system, is constructed, and fig. 2 and 3 are a side perspective view and a top plan view, respectively, of the virtual game object ride vehicle. The arrow points to the position indicating the riding object. The position may be represented, for example, by two coordinates. In an exemplary embodiment of the present disclosure, it is also possible, for example: and respectively allocating index numbers to at least one carrier. Each coordinate may, for example, contain two parts, a coordinate value and a carrier index. The index value may be represented, for example, by an index + number. The above position may be represented as (x, y, z, index0) with respect to the scene; relative to the carrier, can be expressed as (x-x ', y-y ', z-z ', index 1). Where (x, y, z) is the coordinates of the virtual game object being ridden in the scene and (x ', y ', z ') is the coordinates of the vehicle in the scene. index0 and index1 are the index numbers of the scene and the carrier, respectively. A scene can be considered as a stationary, bottommost vehicle, assigned a special index number, e.g. 0. By means of the coordinate representation mode, conversion between any two coordinates on different levels and different vehicles can be achieved. It should be noted that, in this embodiment, only one layer of carrier is given, and actually, the carrier is not limited to one layer, and for the case of a multi-layer carrier, that is, a carrier exists on the carrier, the riding object has a plurality of relative coordinates, and different relative coordinates are identified by different index numbers to indicate the relative positions of the virtual game object to carriers of different layers.
Fig. 4 is a schematic diagram illustrating a method of acquiring position coordinates of a virtual game object according to another exemplary embodiment.
As shown in fig. 4, in an exemplary embodiment of the disclosure, the hierarchical structure data is generated by the second type coordinates and the first type coordinates corresponding to the multi-layer vehicles and the scene according to the hierarchical relationship between the multi-layer vehicles. In the embodiment of the invention, the vehicles in the scene naturally form a tree structure. As shown in fig. 4, there are 3 vehicles in the scene, where vehicle 1 and vehicle 2 are directly located on the scene, and vehicle 3 is located on vehicle 1. The three vehicles and scenes may, for example, form a corresponding tree structure as shown in fig. 5. Vehicle 3 is a child of vehicle 1, and vehicles 1 and 2 are children of the scene. The scene can be regarded as a special carrier, which is always the root node of the tree, and the definition number is 0.
The carriers are stored by the tree structure, so that the mutual relation between the carriers and the scene can be clearly reflected, and for example, when a virtual game object moves, the reachable judgment of the corresponding position can be carried out. May correspond to a landing vehicle, e.g., node 0 to node 1, e.g., from a parent node to a child node; from child node to parent node, corresponding to the leaving carrier, e.g. from node 1 to node 0; from one node to a sibling node, corresponding cross-bearers, e.g. from node 1 to node 2.
As described above, it is possible to generate relative coordinates for vehicles according to a hierarchical structure between the vehicles, respectively, and mark real-time position coordinates of the virtual game object according to the relative coordinates, respectively, when the game object is located on a plurality of vehicles, for example.
According to the method for acquiring the position coordinates of the virtual game object, the position of the virtual game object is marked through the hierarchical structure data, and the problems in the existing carrier processing method can be solved. For example, the conventional carrier processing method cannot accurately represent the movement of the game object on the carrier. The existing carrier processing method basically considers that relative motion does not exist between a carrier and a game object riding the carrier, so that the motion of the carrier and the game object riding is simplified into integral motion, and a relatively complex relative relation can not be expressed actually. For example, the existing carrier processing method uses the carrier and the riding game object as an integral battle unit, thereby simplifying the battle process, and also cannot express complex battle contents, such as battles of a plurality of game objects on the carrier, and even battles between game objects on different carriers.
The current mainstream processing method for taking a virtual game object on a carrier is to establish the association relationship between a player and the carrier by hooking or replacing. The hooking method is to connect the player character model (or the carrier model) as a whole to a preset hooking point of the carrier model (or the player character model), so as to combine the two models into one. The method can keep the appearance expressions of the original two, and can truly reflect the correlation expressions of the two at the same time. For example, a player using a motorcycle or aircraft type vehicle may attach the vehicle directly to the crotch or back attachment points of the player model so that the player's movements or other performance may be consistent with the vehicle in performance. An alternative approach is to replace the player character model directly with the vehicle model. For example, when the player changes to a flying state or enters a fully enclosed carrier, the original appearance of the player is completely invisible, and the player can be directly replaced by a model of the carrier.
Fig. 6 is a schematic diagram illustrating a method of acquiring position coordinates of a virtual game object according to another exemplary embodiment.
As shown in fig. 6, in an exemplary embodiment of the present disclosure, further includes: in an exemplary embodiment of the present disclosure, further comprising: arranging a hanging point on a model skeleton of the carrier; acquiring a first offset vector of a virtual game object relative to a hanging point of a carrier taken by the virtual game object in real time; acquiring a second offset vector of the hanging point in real time; and updating the first type of coordinates of the virtual game object in real time according to the first offset vector and the second offset vector. In an exemplary embodiment of the present disclosure, further comprising: and generating the state effect of the virtual game object in real time through the first type coordinates and the hanging points of the virtual game object.
The carrier is a basic game element, and has a variety of types and various expressions. In many cases, the vehicle model needs to play a motion to improve the performance, such as playing a swaying motion to represent the vehicle jolting during the moving process. The variation of the carrier playing action should further affect the riding object to obtain a correct performance, for example, the riding object swings together with the carrier. As with the conventional vehicle solution, in the embodiment of the present invention, the preset hanging point is adopted to obtain the transformation data of the vehicle action, but the hitching object is not directly hung, but the transformation data of the hanging point is combined with the relative coordinate to calculate the influence of the vehicle action on the hitching object in real time. As shown in fig. 6, which is a forward schematic view of a vehicle model, a skeletal animation with left-right shaking is prefabricated, and a socket is provided on a corresponding skeleton. For later computational convenience, the hitch point may be placed at the origin of the model. Real-time transformation data generated by the carrier action, namely an offset vector generated by the hooking point caused by the carrier action at the moment, is acquired through the hooking point. The transformation generated by the vehicle action can be transmitted to the riding object by adding the offset vector of the riding object relative to the hanging point (if the hanging point is positioned at the origin of the vehicle model, the step can be omitted) and the offset vector of the hanging point according to the coordinate of the riding object relative to the vehicle. And then, the coordinates of the riding object relative to the carrier are converted into a coordinate system relative to the scene, and the state of the riding object is updated, so that the corresponding change of the real-time action of the riding object following the carrier can be realized.
According to the method for acquiring the position coordinates of the virtual game object of the present invention, the state effect of the virtual game object is generated in real time by the first-type coordinates, the second-type coordinates and the hooking points, and the hooking points corresponding to the skeleton of the motion of the carrier are previously created on the carrier, but are not used for hooking the model. In the process of playing the action of the carrier model, the hooking point is used for acquiring the transformation matrix of the action of the carrier model in real time, then the influence of the action of the carrier model on the hitching object is calculated according to the relative coordinates of the hitching object and the hooking point, and the real-time corresponding expression generated by the hitching object following the action change of the carrier where the hitching object is located can be accurately realized.
In an exemplary embodiment of the present disclosure, further comprising: and the virtual game object carries out path addressing planning according to the first type of coordinates and the second type of coordinates. The method comprises the following steps: and performing path addressing planning according to the hierarchical structure data. The hierarchical data may be divided into two layers, one carrier layer and the other scene layer, for example. According to the hierarchical structure between the carriers, a multi-layer coordinate system can be established, and a double-layer sectional strategy can be adopted for routing. The traditional carrier processing method does not support the movement of the riding object relative to the carrier, and the path searching of the riding object relative to the carrier cannot be represented. According to the hierarchical structure among the carriers, the invention firstly calculates the carrier sequence of the path in the movement of the virtual game object, and then generates the moving path mode inside each carrier, thereby realizing the sectional type path-finding strategy of the virtual game object.

The modules of the above embodiments may be combined into one module, or further split into multiple sub-modules.
Through the above description of the embodiments, those skilled in the art will readily understand that the exemplary embodiments described herein may be implemented by software, or by software in combination with necessary hardware. Therefore, the technical solution according to the embodiment of the present invention can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a usb disk, a removable hard disk, etc.) or on a network, and includes several instructions to enable a computing device (which can be a personal computer, a server, a mobile terminal, or a network device, etc.) to execute the method according to the embodiment of the present invention.
From the above detailed description, those skilled in the art can readily appreciate that the method, apparatus, electronic device, and computer-readable medium for acquiring position coordinates of a virtual game object according to the embodiments of the present invention have one or more of the following advantages.
According to some embodiments, the method for acquiring the position coordinates of the virtual game object, disclosed by the invention, can realize correct movement and fighting expression on any carrier when the virtual game object rides the virtual carrier by respectively allocating the absolute coordinates and the relative coordinates to the game scene and the carriers in the scene and marking the position of the virtual game object in the carriers through the relative coordinates, so that the game experience is greatly enriched.
According to other embodiments, the method for acquiring the position coordinates of the virtual game object according to the present invention can solve the problems of the existing carrier processing method by marking the position of the virtual game object with data having a hierarchical structure. For example, the conventional carrier processing method cannot accurately represent the movement of the game object on the carrier. The existing carrier processing method basically considers that relative motion does not exist between a carrier and a game object riding the carrier, so that the motion of the carrier and the game object riding is simplified into integral motion, and a relatively complex relative relation can not be expressed actually. For example, the existing carrier processing method uses the carrier and the riding game object as an integral battle unit, thereby simplifying the battle process, and also cannot express complex battle contents, such as battles of a plurality of game objects on the carrier, and even battles between game objects on different carriers.
According to still other embodiments, the method for acquiring the position coordinates of the virtual game object of the present invention adopts a double-layer sectional type path-finding strategy to resolve the movement path-finding of the riding object into three modes, i.e., movement on a carrier, movement between carriers, and movement between a carrier and a scene, so as to realize the path-finding of the riding object between any two points.
Exemplary embodiments of the present invention are specifically illustrated and described above. It is to be understood that the invention is not limited to the precise construction, arrangements, or instrumentalities described herein; on the contrary, the invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
In addition, the structures, the proportions, the sizes, and the like shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be understood and read by those skilled in the art, and are not used for limiting the limit conditions which the present disclosure can implement, so that the present disclosure has no technical essence, and any modification of the structures, the change of the proportion relation, or the adjustment of the sizes, should still fall within the scope which the technical contents disclosed in the present disclosure can cover without affecting the technical effects which the present disclosure can produce and the purposes which can be achieved. In addition, the terms "above", "first", "second" and "a" as used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present disclosure, and changes or modifications of the relative relationship may be made without substantial technical changes and modifications.
