Switch to Scripting

The Box Collider is a basic cube-shaped collision primitive.


Property: Function:
Is Trigger If enabled, this Collider is used for triggering events, and is ignored by the physics engine.
Material Reference to the Physics Material that determines how this Collider interacts with others.
Center The position of the Collider in the object’s local space.
Size The size of the Collider in the X, Y, Z directions.


Box colliders are obviously useful for anything roughly box-shaped, such as a crate or a chest. However, you can use a thin box as a floor, wall or ramp. The box shape is also a useful element in a compound collider.
