In this chapter, you learned the different ways to handle performance. You learned about different Physics components and the ways they can be used for better performance. You learned how to use a single collider for a complex object, that we should not use multiple cloth components in one game, and that we can optimize graphics by reducing the number of draw calls.

This book is all about learning Physics with Unity3D. We saw that Unity has a powerful Physics engine. You learned about the different Physics components provided by Unity3D to make a developer's life easier. You learned how to use Physics when creating animations. Now, you are set to learn about networking and multiplayer game and application using Unity3D.
