Description
Technical Field
The present invention relates to the field of computers, and in particular, to a method, an apparatus, a processor, and a terminal for generating a three-dimensional game map.
Background
Currently, in most game scenes, a map is usually set. The map is typically a thumbnail of the game scene. Some important places, route information and the like in the game scene are marked in the map. The game player can quickly learn the current position of the game role controlled by the player through the map, the route to the destination and other information.
Related art maps within a game scene are typically represented in a two-dimensional (2D) implementation, i.e., in the form of one 2D picture. In terms of game performance, it is common to add some important information on 2D pictures, such as: important place names, routes, the current game character location, etc. In terms of game operations, zooming and moving of a map are generally supported, and meanwhile, some operations such as punctuation and line drawing are supported by a game player.
However, such a 2D map implementation can exhibit a certain mapping function, but has a significant technical disadvantage of insufficient expressivity. For example: although place names or place information can be noted on a map, such a textual description lacks intuitiveness for a game player; meanwhile, in terms of operation, the control operation for the 2D map is generally limited to only a zoom map operation and a moving map operation.
In view of the above problems, no effective solution has been proposed at present.

In this embodiment, there is provided a method for generating a three-dimensional game map running on the computer terminal (or mobile device), and fig. 2 is a flowchart of a method for generating a three-dimensional game map according to one embodiment of the present invention, as shown in fig. 2, the method includes the steps of:
step S202, creating a first game scene, wherein the first game scene is a blank game scene;
step S204, adding a preconfigured three-dimensional map model and map information corresponding to the three-dimensional map model to the first game scene;
step S206, creating a rendering target, and rendering scene contents contained in the first game scene to a target map bound by the rendering target;
step S208, rendering the target map to the target object in the current game interface.
Through the steps, a blank game scene is created, a preconfigured three-dimensional map model and map information corresponding to the three-dimensional map model are added to the blank game scene, a rendering target is created, scene content contained in a first game scene is rendered to a target map bound by the rendering target, and the target map is rendered to a target object in a current game interface, so that the purpose of realizing a 3D map effect in the game scene and simultaneously being compatible with various operation modes of a 2D map is achieved, the technical effect that map experience is more visual and smooth in game performance and game operation is achieved, and the technical problems that the two-dimensional game map implementation mode provided in the related technology lacks of visual performance and has limitation on control operation of the game map are solved.
Optionally, in step S204, adding the three-dimensional map model to the first game scene may include performing the steps of:
step S2041, obtaining a first information set, wherein the first information set includes: position information, rotation information and scaling information of the three-dimensional map model in the first game scene;
step S2042, adding a three-dimensional map model to the first game scene in accordance with the first information set.
In order to realize the effect of the 3D map in the game, the 3D map model is required to be rendered, and corresponding map information (comprising place name information, other models or special effects which need to be identified in the map and the like) is required to be rendered at a specific position on the 3D map model. To this end, a blank game scene is created in the game, and a camera is provided in the blank game scene to facilitate the subsequent rendering of the 3D map model. Each game item may typically create multiple game scenes at the same time, but typically only the content covered by one of the game scenes can be displayed at the same time.
The purpose of creating the blank game scene is to: to add 3D map models, 3DUI, models, and special effects to the blank game scene alone. The blank game scene and the normal game scene are mutually independent. After the blank game scene is created, a 3D map model with a certain scale is also required to be created, the 3D map model is added into the created blank game scene based on the position information, rotation information and scaling information of the 3D map model in the blank game scene, and then the scene added with the 3D map model is rendered into a current game interface.
It should be noted that, the following two ways may be generally adopted to add the 3D map model to the current game interface:
in the first mode, the 3D map model is directly added to the current game interface.
And secondly, creating a blank game scene, adding the 3D map model into the blank game scene, and then rendering the scene added with the 3D map model into the current game interface.
Considering that additional effects are required to be added to the scene where the 3D map model is added later, including, but not limited to, special effects (such as a route, a preview line and a range circle) and models (such as a point selection mark) which are only used in the display process of the 3D map model, and special post-processing of the scene where the 3D map model is located are performed (such as rendering the scene where the 3D map model is located into a map separately, then adding four angles to the map to darken, and highlighting the post-processing effect of the intermediate map), in an alternative embodiment, a blank game scene is additionally created, and then the 3D map model is added to the blank game scene.
Alternatively, in step S204, adding map information to the first game scene may include performing the steps of:
Step S2043, calculating a third information set using the first information set and a second information set, wherein the second information set includes: position information, rotation information, and zoom information of the map information relative to the three-dimensional map model, the third set of information comprising: position information, rotation information and zoom information of map information in a first game scene;
step S2044, adding map information to the first game scene in accordance with the third information set.
In an alternative embodiment, creating map information pertaining to a 3D map model includes: place names (i.e., 3DUI mainly refers to place names used in 3D map models, which differ from 2DUI in that 3DUI resembles a 3D model, which can be added to a 3D scene, while 3DUI also has 3D position, 3D rotation, etc.), labels (special effects or models), etc. The relative position and relative rotation information between these map information and the 3D map model are calculated and added to the blank game scene that has been created. Here, a matrix may be employed to represent a matrix relationship between map information and a 3D map model. Hypothesis matrix M map Representing the position, rotation and scaling (corresponding to the first information set) of the 3D map model in the blank game scene, and M other For representing the position, rotation and scaling (corresponding to the second set of information) of the map information on the 3D map model relative to the 3D map model, then finally M is adopted other *M map To represent map information in blank game scenesPosition, rotation and scaling (corresponding to the third set of information described above).
Optionally, after rendering the scene content included in the first game scene to the target map in step S206, the following steps may be further performed:
step S207, performing image processing on the target map, wherein the image processing comprises at least one of the following steps: color superimposing processing, highlighting processing.
Any one game scene created in the game needs to specify a rendering target (RenderTarget). A rendering object binds a map and the content contained in the game scene is rendered into the bound map. A default rendering target (Default RenderTarget) is typically set in the game to render the main scene in the game to the default rendering target, and the content displayed by the game interface is typically a specific map to which the default rendering target is bound. Therefore, a rendering target needs to be created for the blank game scene, and all the added contents (including a map model, a 3DUI, special effects, a model and the like) in the blank game scene are rendered into a map bound with the rendering target. Since this alternative embodiment adds the 3D map model and some corresponding map information to a blank game scene, the scene in which the 3D map model is located needs to be rendered into a target map bound by a designated RenderTarget.
In an alternative embodiment, some image effect processing may be performed on the rendered map, including but not limited to: color superimposing processing, highlighting processing, and the like. And then rendering the processed 2D map with the 3D map model and the special map information on the current game interface. For example: the final 3D map effect is achieved by rendering the 2D map to a target object, such as the glass of the cockpit. For another example: the 2D map may be rendered directly onto the current game interface as a UI eidolon node.
Optionally, after rendering the target map to the target object in step S208, the following steps may be further included:
step S209, receiving an operation instruction acting on the three-dimensional map model;
step S210, a control operation corresponding to the operation instruction is performed on the three-dimensional map model.
Corresponding control operations are defined according to different types of operation platforms. Here, the types of the operation platform mainly include: personal computers (PC platforms) and mobile platforms. In general, control operations of the PC platform for the display screen are performed using a mouse, and control operations of the mobile platform for the display screen are performed using multi-finger touch. Thus, it is necessary to define corresponding operation schemes according to different types of operation platforms, respectively.
Whereas different 3D map control operations are defined on the PC platform primarily in terms of different mouse operations, they may include, but are not limited to: clicking the mouse is marking point selection operation, pressing a left button of the mouse and sliding the left button into movement operation, pressing a right button of the mouse and sliding the right button into rotation operation, and operating the mouse wheel into zooming operation. While different 3D map control operations are defined on the mobile platform primarily according to different multi-finger touch operations, they may include, but are not limited to: the single-finger touch click is a mark point selection operation, the single-finger click and slide is a movement operation, the double-finger click and slide is a rotation operation, and the double-finger distance is scaled to be a scaling operation. Thus, according to different operation instructions, corresponding operations are executed on the 3D map model.
Alternatively, when the operation instruction is a click instruction, performing a control operation corresponding to the operation instruction on the three-dimensional map model in step S210 may include performing the steps of:
step S2100, obtaining a first two-dimensional coordinate of a screen click position under a screen coordinate system;
step S2101, converting the first two-dimensional coordinates into first three-dimensional coordinates in world coordinates;
step S2102, converting the first three-dimensional coordinate into a second two-dimensional coordinate under a UV coordinate system of a target object;
Step S2103, converting the second two-dimensional coordinates into second three-dimensional coordinates in the three-dimensional space coordinate system of the first game scene;
in step S2104, a marker model is added to the location of the second three-dimensional coordinate.
When the operation instruction is a click instruction, the 3D map model and the scene where the 3D map model is located are required to be rendered on a piece of 2D map, and the piece of 2D map is rendered on glass of the cockpit. Thus, for the click marking operation, this is typically done in the following manner: for 3D games, if a game player clicks on a screen, the actual intent of the game player is to click on a specific 3D location in the game scene, whereas cameras in current 3D game engines are typically provided with an interface (i.e. screen posto world pos) that functions to convert the 2D planar coordinates of the screen into the 3D world coordinates of the game scene. Thus, when a gamer clicks on the current screen (cell phone screen or computer screen), the gamer's actual intention is to actually click on a specific location on the cockpit glass. At this point, the interface screenpostoworld pos in the camera of the current scene needs to be invoked to perform the first conversion.
Fig. 3 is a schematic diagram of converting a click coordinate of a game player into a mapped UV coordinate according to an alternative embodiment of the present invention, as shown in fig. 3, assuming that a screen coordinate clicked by the game player is (x, y) corresponding to the first two-dimensional coordinate, and a coordinate obtained by the first conversion of the camera is (x 1, y1, z 1), where (x 1, y1, z 1) is a coordinate of a corresponding point on the cabin glass corresponding to the first three-dimensional coordinate. Meanwhile, (x 1, y1, z 1) can also be converted into uv coordinates (u, v) used on the glass plane by using the engine interface, which corresponds to the second two-dimensional coordinates described above.
In addition, the map on the glass is exactly one 2D map obtained by rendering the scene where the 3D map model is located. FIG. 4 is a schematic diagram of converting UV coordinates of a map into 3D coordinates of a scene where a 3D map model is located according to an alternative embodiment of the present invention, as shown in FIG. 4, a camera set in the blank game scene may be used to recall the Screen PosToWorldPos to convert coordinates (u, v) into 3D space coordinates (fx, fy, fz) used in the blank game scene, which corresponds to the second three-dimensional coordinates, where the (fx, fy, fz) is a specific location that the game player finally wants to click on. Therefore, only one mark model (which is an arrow model used for representing that a user clicks a specific position of the 3D map) is added at a specific position in the blank game scene, so that the point selecting operation of the 3D map can be completed.
Alternatively, when the operation instruction is a movement instruction, performing a control operation corresponding to the operation instruction on the three-dimensional map model in step S210 may include performing the steps of:
step S2105, acquiring first position information, a first vector corresponding to a movement instruction and a first scale, wherein the first position information is an initial position of the three-dimensional map model before receiving the movement instruction;
Step S2106, determining second position information by adopting the first position information, the first vector and the first scale, wherein the second position information is a target position of the three-dimensional map model after receiving the moving instruction;
step S2107, performing a moving operation on the three-dimensional map model according to the second position information.
When the operation instruction is a move instruction, it is easier to implement relative to the point selection operation for the move operation. On the PC platform, a game player presses a left button of a mouse and slides; on the mobile platform, the game player clicks and slides on the screen with a single finger. The target position can be determined by recording the direction vector of the slide and the slide distance. Assuming that the sliding direction vector is (ax, ay), which corresponds to the first vector, and the sliding scale is defined as k (which corresponds to the first scale), the initial position of the 3D map model (which corresponds to the first position information) is (x 0, y0, z 0), the moved target position (which corresponds to the second position information) is: (x 1, y1, z 1) = (x 0, y0, z 0) +k (ax, ay, 0).
Alternatively, when the operation instruction is a rotation instruction, performing a control operation corresponding to the operation instruction on the three-dimensional map model in step S210 may include performing the steps of:
Step S2108, when the second vector corresponding to the rotation instruction is located in the first section, controlling the three-dimensional map model to rotate around the first coordinate axis according to the first direction; when the second vector is located in the second interval, the three-dimensional map model is controlled to rotate around the first coordinate axis according to a second direction, wherein the second direction is opposite to the first direction; when the second vector is located in the third interval, the three-dimensional map model is controlled to rotate around the second coordinate axis according to the first direction; and when the second vector is positioned in the fourth interval, controlling the three-dimensional map model to rotate around the second coordinate axis according to the second direction.
When the operation instruction is a rotation instruction, for the rotation operation, similar to the movement operation, on the PC platform, the game player holds the right mouse button and slides; on the mobile platform, the game player clicks and slides with two fingers on the screen. Fig. 5 is a schematic diagram of a rotation operation for a 3D map model according to an alternative embodiment of the present invention, as shown in fig. 5, since the rotation operation can be simultaneously performed around multiple axes, taking a two-dimensional rectangular coordinate system of a screen as an example, when a sliding vector is in an α1 interval (which corresponds to the first interval), for example: (45 degrees, 135 degrees), the 3D map model rotates forward (which corresponds to the first direction described above) about the x-axis; when the sliding vector is in the α2 interval (which corresponds to the second interval described above), for example: (-135 degrees, -45 degrees), the 3D map model is rotated reversely around the x-axis (which corresponds to the above second direction). When the sliding vector is in the β1 region (which corresponds to the third region described above), for example: (-45 degrees, 45 degrees), the 3D map model is rotated forward about the y-axis; when the sliding vector is in the β2 region (which corresponds to the fourth region described above), for example: (135 degrees, -135 degrees), the 3D map model is rotated reversely around the y-axis.
Alternatively, when the operation instruction is a zoom instruction, performing a control operation corresponding to the operation instruction on the three-dimensional map model in step S210 may include performing the steps of:
step S2109, obtaining an initial scaling value, a scaling distance and a second scale;
step S2110, determining a target scaling value by adopting the initial scaling value, the scaling distance and the second scale;
step S2111, a scaling operation is performed on the three-dimensional map model in accordance with the target scaling value.
When operatingWhen the instruction is a zoom instruction, the zoom operation is performed by a roller operation on the PC platform, and the zoom operation is performed by a double-finger zoom or a zoom-out distance on the mobile platform. Assuming that the zoom distance of the roller or the double finger is dx, the zoom scale is k (corresponding to the second scale), and the initial zoom value is S O The target scaling value is S O +dx*k。
Optionally, after performing the control operation corresponding to the operation instruction on the three-dimensional map model in step S210, the following performing step may be further included:
step S211, obtaining an updated first information set obtained by executing control operation on the three-dimensional map model;
step S212, determining an updated third information set based on the updated first information set;
Step S213, determining updated scene content contained in the first game scene according to the updated first information set and the updated third information set;
step S214, rendering the updated scene content to a target map;
step S215, render the target map to the target object.
Matrix M due to 3D map model map Because of the change, the spatial position, rotation, scaling, etc. of other marks (such as place names, heading, etc.) with the 3D map model as a parent node also need to be updated synchronously. The scene content is then re-rendered into the target map bound by the RenderTarget. And finally, refreshing the content of the target map bound by the RenderTarget onto the glass of the cockpit, thereby realizing the control operation of the 3D map model.
