Chapter 10Project: Collisions
When you’re done with this chapter, you will
-
Be able to stop game elements from moving through each other
-
Understand collisions, which are important in gaming
-
Have game boundaries for your avatar
We have a pretty slick game avatar. It moves, it walks, it even turns. But you may have noticed something odd about our avatar. It can walk through trees.
In this chapter we’ll use tools that are built into our Three.js 3D JavaScript library to prevent the avatar-in-a-tree effect. (As we’ll see in other chapters, there are other ways to do the same thing.)
