how to destroy an item after collision

问题

I am creating an fps game, I have created the gun, the bullet, and the enemy. Now I want to make my enemy destroyed after the collision with bullet. My enemy is a gameobject named Fire and tagged Enemy and my bullet named "Cube 1(Clone)" and tagged "Cube 1(Clone)". I made a script for that:

#pragma strict

function OnTriggerEnter(theCollision : Collider)
{
    if(theCollision.gameObject.name=="Cube 1") 
    {
        Destroy(gameObject);
        Debug.Log("Dead");
    }
}

But it does not work.

回答1:

You need to check the tag not the name. You could check for name but remember it will have "(Clone)".

function OnTriggerEnter(theCollision : Collider)
{
    if(theCollision.tag == "Cube 1") 
    {
        Destroy(gameObject);
        Debug.Log("Dead");
    }
}

If you are not sure that you tagged correctly, you can simply use both checks in your if statement.

if(theCollision.tag == "Cube 1" || theCollision.gameObject.name == "Cube 1(Clone)") 
    Destroy(gameObject);

回答2:

Well since the bullet is tagged Cube 1(Clone) , I would use

if(theCollision.tag == "Cube 1(Clone)"){...}

And would probably would rename the tag to something meaningful, say bullet.
