  • Namespace: UnityEngine
  • Assembly: UnityEngine.PhysicsModule
public static void IgnoreCollision(Collider collider1, Collider collider2, bool ignore)

Parameters

collider1

Collider
Any collider.

collider2

Collider
Another collider you want to have 
collider1
to start or stop ignoring collisions with.

ignore

bool
Whether or not the collisions between the two colliders should be ignored or not.

Remarks

This is useful, say, for preventing projectiles from colliding with the object that fires them.
Note that Physics.IgnoreCollision is not persistent. This means ignore collision state will not be stored in the editor when saving a scene.
If 
ignore
is false, collisions can occur. Set 
ignore
to true to ignore collisions.

using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour{    public Transform bulletPrefab;    void Start()    {        Transform bullet = Instantiate(bulletPrefab) as Transform;        Physics.IgnoreCollision(bullet.GetComponent<Collider>(), GetComponent<Collider>());    }}
