Remarks
Determining if Colliders can come into contact involves multiple checks including:
- Each Collider2D must be active and enabled. See Behaviour.isActiveAndEnabled.
- Each Collider2D must be on a GameObject that is in the same PhysicsScene2D. By default, this is true but see PhysicsSceneExtensions2D.GetPhysicsScene2D and LocalPhysicsMode.Physics2D.
- Each Collider2D that is attached to a Rigidbody2D must have a compatible Rigidbody2D.bodyType. For instance RigidbodyType2D.Static cannot contact another RigidbodyType2D.Static. Without a Rigidbody2D, the Collider2D is implicitly Static. Kinematic vs Kinematic/Static will only contact if Rigidbody2D.useFullKinematicContacts is enabled.
- The Collider2D will not contact if they are specified using Physics2D.IgnoreCollision.
- The Collider2D will not contact if they are part of an Effector2D that is using Effector2D.useColliderMask.
- The Collider2D will not contact if their layer collision (in the Layer Collision Matrix) is set to not contact unless overriden using the Rigidbody2D and Collider2D layer overrides.
