Summary
Navigation meshes are an important part of game AI. In this chapter, we looked at
the different parameters to customize navigation meshes. We looked at things such
as setting the character size and walkable slopes and discussed the importance of
the cell size parameter. We then saw how to customize our mesh by tagging differ-
ent areas as not walkable and how to set up multiple navigation meshes for different
characters.
We now have all the essential skills we need to create AI in Unity. We've seen how to
have a character move, navigate, and sense other characters in our game scenes as
well as how to set up behavior trees to make decisions and integrate animation. We
also looked at different AI use cases, such as crowds, driving, and had our characters
attack and change behavior based on game events. This covers a lot about AI, but
game AI is a huge and much studied topic and there is much more to learn. By doing
some searching, you'll find that there are many online articles, textbooks, and confer-
ence talks that you can study to make even more advanced AI.
