Research and Implementation of Key Technologies of Android Platform Games Based on Unity3D

In this paper, the key technologies of Android platform game based on Unity3D are studied and implemented. Users can control the characters in the game and interact with the content in the game on the Android platform. The core agent of the game consists of functional modules such as protagonist motion control, physical collision detection, animation controller, game scene layout, camera control, game character AI control, finite state machine, and game subject control. The motion control module of the protagonist mainly uses the physics engine of Unity3D, and realizes the state change of the protagonist by writing the corresponding C# script. The unique animation components of Unity3D are used to realize the animation effect by playing the material frame by frame, and the switch between the animations is realized through the animation controller. The camera control adopts the principle of orthogonal camera, and uses relevant plug-ins to realize the basic functions of following and stopping the game screen. Screen post-processing Bloom, the screen post-processing of URP general rendering pipeline, is used to improve the picture of the game. Abstract class inheritance and finite state machine are used to control the AI of game characters.
