Brief Description

Concave polygon 2D shape resource for physics.

Member Functions

Vector2Array get_segments ( ) const
void set_segments ( Vector2Array segments )


Concave polygon 2D shape resource for physics. It is made out of segments and is very optimal for complex polygonal concave collisions. It is really not advised to use for RigidBody2D nodes. A CollisionPolygon2D in convex decomposition mode (solids) or several convex objects are advised for that instead. Otherwise, a concave polygon 2D shape is better for static collisions.

The main difference between a ConvexPolygonShape2D and a ConcavePolygonShape2D is that a concave polygon assumes it is concave and uses a more complex method of collision detection, and a convex one forces itself to be convex in order to speed up collision detection.

Member Function Description

Vector2Array get_segments ( ) const
