Collider2D.CanContact

Parameters

Returns

bool Returns true if both Colliders can contact each other otherwise false indicating that they cannot contact each other.

Description

This method determines if both Colliders can ever come into contact.

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.
