ManifoldPoint Class

Module: cc

A manifold point is a contact point belonging to a contact manifold. It holds details related to the geometry and dynamics of the contact points. Note: the impulses are used for internal caching and may not provide reliable contact forces, especially for high speed collisions.

Properties
  • localPoint Vec2 The local point usage depends on the manifold type: -e_circles: the local center of circleB -e_faceA: the local center of circleB or the clip point of polygonB -e_faceB: the clip point of polygonA
  • normalImpulse Number Normal impulse.
  • tangentImpulse Number Tangent impulse.
