Collision settings are fairly easy to get started with. There are three classes of intersection for collisions:
- Ignore: Collisions that pass through each other without any notification.
- Overlap: Collisions that trigger the OnBeginOverlap and OnEndOverlap events. Interpenetration of objects with an Overlap setting is allowed.
- Block: Collisions that prevent all interpenetration, and prevent objects from overlapping each other at all.
