CustomCollider2D.customShapeCount

描述

The total number of custom PhysicsShape2D assigned to the Collider. (Read Only)

All the shapes represented here contain a total vertex count of customVertexCount.

NOTE: This property should not be confused with Collider2D.shapeCount which is a count of active shapes on the Collider2D. The CustomCollider2D has this property too. If a Collider2D is disabled, inactive or in error then the Collider2D.shapeCount will be zero whereas the customShapeCount will always be a count of assigned custom PhysicsShape2D.
