Summary
By completing this chapter, you have added a new tool to your belt: Line Traces. You now know how to execute Line Traces and Sweep Traces, both Single and Multi; how to change an object's response to a specific Trace Channel; and how to create your own Trace Channels.
You will quickly realize in the chapters ahead that these are essential skills when it comes to game development, and you will make good use of them on your future projects.
Now that we know how to use Line Traces, we're ready for the next step, which is Object Collision. In the next chapter, you will learn how to set up collisions between objects and how to use collision events to create your own game logic. You will create the Dodgeball Actor, which will be affected by real-time physics simulation; the Wall Actors, which will block both the characters' movements and the dodgeball; and the Actor responsible for ending the game when the player comes into contact with it.
