A Collider that can merge other Colliders together.
A CompositeCollider2D merges other Colliders together when their Collider2D.usedByComposite is set to true.
When a Collider is used by a Composite Collider, the Editor will ignore and not show the Collider2D.sharedMaterial, Collider2D.isTrigger & Collider2D.usedByComposite properties. The same properties on the CompositeCollider2D will be used instead. You should set these properties on the Composite Collider instead to merge all Colliders into the Composite Collider.
Composite Colliders can only merge BoxCollider2D and PolygonCollider2D.
