Physics messages (3D)

There are two types of physics messages, collisions and triggers.
Decide which type of interaction you want before implementing a message.
Physics messages are sent to scripts attached to both bodies.

Collisions

Collisions are physical interactions between two solid bodies.

Triggers

Triggers can be passed through. Trigger messages are sent when two bodies touch where at least one is non-solid.
