contactCountGets the number of contacts for this collision.
contactsThe specific points of contact with the incoming Collider2D. You should avoid using this as it produces memory garbage. Use GetContact or GetContacts instead.
enabledIndicates whether the collision response or reaction is enabled or disabled.
gameObjectThe incoming GameObject involved in the collision.
otherColliderThe other Collider2D involved in the collision with the collider.
otherRigidbodyThe other Rigidbody2D involved in the collision with the rigidbody.
relativeVelocityThe relative linear velocity of the two colliding objects (Read Only).
rigidbodyThe incoming Rigidbody2D involved in the collision with the otherRigidbody.
