Whether or not this pair is equivalent to a pair reported in MonoBehaviour.OnCollisionEnter events.
Whether or not this pair is equivalent to a pair reported in MonoBehaviour.OnCollisionEnter events.
Whether or not this Collider generates contacts for Physics.ContactEvent.
Describes a collision.
The contact points generated by the physics engine. You should avoid using this as it produces memory garbage. Use GetContact o...
Describes a contact point where the collision occurs.
The distance between the colliders at the contact point.
Subscribe to this event to read all collisions that occurred during the physics simulation step.
Whether or not MonoBehaviour collision messages will be sent by the physics system.
Determines whether the garbage collector should reuse only a single instance of a Collision type for all collision callbacks.
The Layers that this Collider2D will report collision or trigger callbacks for during a contact with another Collider2D.
The layers of other Collider2D involved in contacts with this Collider2D that will be captured.
Sent when a collider on another object stops touching this object's collider (2D physics only).
Sent each frame where a collider on another object is touching this object's collider (2D physics only).
Collision details returned by 2D physics callback functions.
Gets the distance between the colliders at the contact point.
