Class StaticCollisionPoint

java.lang.Object

org.mini2Dx.gdx.math.Vector2

org.mini2Dx.core.geom.Point

org.mini2Dx.core.collision.util.StaticCollisionPoint

All Implemented Interfaces:

java.io.Serializable, CollisionObject, Positionable, Interpolatable, org.mini2Dx.gdx.math.Vector<org.mini2Dx.gdx.math.Vector2>, org.mini2Dx.gdx.utils.Disposable

public class StaticCollisionPoint
extends Point
implements CollisionObject

An implementation of a collision point that will not move between updates/frames, thus, does not register as an interpolating collision. Due to this, memory and CPU overhead are reduced compared to using the CollisionPoint implementation.
