bodyThe Rigidbody or ArticulationBody of the collider that your Component collides with (Read Only).
colliderThe Collider we hit (Read Only).
contactCountGets the number of contacts for this collision.
contactsThe contact points generated by the physics engine. You should avoid using this as it produces memory garbage. Use GetContact or GetContacts instead.
gameObjectThe GameObject whose collider you are colliding with. (Read Only).
impulseThe total impulse applied to this contact pair to resolve the collision.
relativeVelocityThe relative linear velocity of the two colliding objects (Read Only).
rigidbodyThe Rigidbody we hit (Read Only). This is null if the object we hit is a collider with no rigidbody attached.
