两件文件，自行解压,(附src) 1/2 This book shows how to implement various AI techniques in Unity3D by implementing the algorithm from scratch using C#, applying Unity3D built-in features, or using available scripts and plugins from the Unity Asset Store. For example, we’ll be implementing our own A* algorithm to do pathfinding but will also explore the Unity3D navigation graphs feature. Then we’ll use the Behave plugin to construct behavior trees for intelligent AI character behaviors.
