Unity Artificial Intelligence Programming - Fourth Edition

Summary

In this chapter, we set up two scenes and studied how to build path-following agents with obstacle avoidance behavior. We learned about the Unity3D layer feature and how to selectively raycast against a particular layer. Although these examples were simple, we can apply these simple techniques to various scenarios. For instance, we can set up a path along a road, and by using some vehicle models combined with obstacle avoidance behavior, we can easily set up a decent traffic simulation. Alternatively, you could just replace them with biped characters and build a crowd simulation. You can also combine them with some finite state machines to add more behaviors and make them more intelligent. The simple obstacle avoidance behavior that ...
