Destroy-able won't destroy

Questions & Answers

i have this script that when a bullet hits a destoryable tagged object it will destroy itself and the object it hits.

	void OnCollisionEnter(Collider col)
	{
		if (col.gameObject.tag == "Destroyable")
		{
			Destroy(col.gameObject);
			Destroy(this.gameObject);
		}
	}

the object im using to test is a sphere and has a rigidbody and sphere colider. the bullet is the same but smaller and with an “Ammo” tag.

OnCollisionEnter doesn’t get a Collider as parameter but a Collision object. Only OnTriggerXXX functions just get the triggering collider.

A collision can have multiply contact points but at least 1

So you might want to change your code to:

void OnCollisionEnter(Collision col)
{
    if (col.collider.gameObject.tag == "Destroyable")
    {
        Destroy(col.collider.gameObject);
        Destroy(gameObject);
    }
}
