Switch to Scripting

The Box Collider 2D component is a collider for use with 2D physics. The collider’s shape is a rectangle with a given position, width and height in the local coordinate space of a Sprite. Note that the rectangle is axis-aligned, ie, its edges are parallel to the X or Y axes of local space.

Property: Function:
Material A physics material that determines properties of collisions, such as friction and bounce.
Is Trigger Does the collider behave as a trigger?
Size Width and height of the rectangle in local space units.
Center Centre coordinate of the rectange in local space.
