Description
Technical Field
The invention relates to the technical field of game production, in particular to a game production scheme based on a Unity engine and capable of shortening game development time and improving game visual effect and game performance, and particularly relates to a method and a system for realizing a 3D-simulated game effect in a 2D resource mode.
Background
In general, 3D game creation is to create a 3D game model using 3DS MAX, MAYA, or other model software, create a map using ps (adobe photoshop), ae (adobe After effects), or other picture editing software, produce a corresponding game resource using other resource production tools, and finally import the game resource to a game Engine such as Unity or non-regional Engine to develop a corresponding game.
The existing 3D game making technical scheme is as follows:
and the first scheme is that the software is adopted to generate a 3D model and a corresponding 2D map in the game, and the 3D game scene is edited in a corresponding engine, so that the expression effect of the 3D game is realized.
And secondly, manufacturing a 3D model and a corresponding 2D material mapping by adopting the software, rendering the 3D scene into a 2D picture after the scene is built, or directly obtaining the 2D picture by hand drawing, and combining the 2D pictures with the orientation of a game camera in a certain scene building mode to realize the expression effect similar to a 3D game.
And on the basis of the second scheme, some game objects which need to be subjected to emphasis expression or easily cause visual lasting are made into a 3D model, and the rest game objects are realized in a 2D map form, so that a more vivid 3D game expression effect than the second scheme is realized.
The prior art has the following defects:
1. the 3D effect obtained by rendering the game manufactured by the first scheme is best in performance, however, compared with the 2D game, the 3D game needs more complex manufacturing flow and personnel configuration, and the time period and cost for manufacturing the game are greatly increased. In addition, the 3D model detail degree and the screen rendering efficiency in the 3D game are inversely proportional, and the game performance is consumed for a game with a high requirement for detail expression.
2. The second scheme realizes the representation effect of the 3D game by rendering the 3D scene into 2D pictures, because a 3D model is abandoned, the performance is improved, but another problem is introduced, at the moment, the game is still 2-dimensional, generally, the camera and the player move on an XY plane, and the concept of depth in the 3D game is not available, so that the problem of the shielding relation between each 2D picture and other pictures can be caused. (e.g., occlusion of player objects and 2D objects)
