Public Attributes | |
b2Vec2 | localPoint1 |
local position of the contact point in body1 | |
b2Vec2 | localPoint2 |
local position of the contact point in body2 | |
float32 | separation |
the separation of the shapes along the normal vector | |
float32 | normalForce |
the non-penetration force | |
float32 | tangentForce |
the friction force | |
b2ContactID | id |
uniquely identifies a contact point between two shapes |
It holds details related to the geometry and dynamics of the contact points. The point is stored in local coordinates because CCD requires sub-stepping in which the separation is stale.
