Solid
From Castle Wiki
Solid is a behavior that that determines whether the actor can overlap with other actors during a collision.
Solid actors can behave differently depending on what kind of Motion they have.
- Solid actors with no motion (for example, walls) will never change position after a collision.
- Actors with fixed motion will avoid changing their velocity after a collision.
- Actors with dynamic motion may change both their position and their velocity after a collision. They are pushed away by other solid actors.
