Collision Channels

In the previous chapter, we took a look at the existing Trace Channels (Visibility and Camera) and learned how to make our own custom channel. Now that you know about Trace Channels, it's time to talk about Object Channels, also known as Object Types.

While Trace Channels are only used for Line Traces, Object Channels are used for object collision. You can specify a "purpose" for each Object Channel, much like with Trace Channels, such as Pawn, Static Object, Physics Object, Projectile, and so on. You can then specify how you want each Object Type to respond to all the other Object Types by blocking, overlapping, or ignoring objects of that type.
