We have learnt a lot in this chapter about detecting collisions between characters and adding action to our games. Specifically, we were able to determine whether a collision has occurred between two characters. We used AI algorithms to simulate realistic behaviors and to give the player the chance to win. We created chasing, evasion, and wandering algorithms and we added them to existing 3D characters. We also understood how to generate and control random situations.
Now that we've learnt to detect collisions and to apply artificial intelligence to win, we're ready to apply special effects, which is the topic of the next chapter.
