Physics.IgnoreCollision

static function IgnoreCollision (collider1 : Collider, collider2 : Collider, ignore : bool = true) : void

Description

Makes the collision detection system ignore all collisions between collider1 and collider2.

This is most useful for making eg. projectiles not collide with the object shooting them.

IgnoreCollision has a few limitations: 1) It is not persistent. This means ignore collision state will not be stored in the editor when saving a scene. 2) You can only apply the ignore collision to colliders in active game objects. When deactivating the collider or attached rigidbody the IgnoreCollision state will be lost and you have to call Physics.IgnoreCollision again.

// Instantiate a bullet and make it ignore collisions with this object.
var bulletPrefab : Transform;
function Start () {
var bullet = Instantiate (bulletPrefab);
Physics.IgnoreCollision(bullet.collider, collider);
}
