| collider | A collider used to calculate the minimum distance against all colliders attached to this Rigidbody2D. |
ColliderDistance2D
The minimum distance of collider against all colliders attached to this Rigidbody2D.
Calculates the minimum distance of this collider against all Collider2D attached to this Rigidbody2D.
The provided collider will be check against all Collider2D attached to this Rigidbody2D and the minimum distance from all attached Collider2D will be returned.
The provided collider and at least one Collider2D attached to this Rigidbody2D must be valid for the returned ColliderDistance2D to be valid i.e. the Collider2D should not be disabled and must contain collision shapes and the provided collider must not be NULL. You can check if the returned value is valid by checking ColliderDistance2D.isValid.
