Question by Albert 2 · Oct 28, 2010 at 10:59 PM · destroyinstance

how to destroy an instance of multiple prefabs

in my game i have enemies dropping health when they die...i have a script working to find out when the player collides with the health but my problem is, when the player collides, all the health instances in the scene get destroyed...how can i make it so only the one instance i interact with is the one that gets destroyed...i have the following script attached to the player:

function OnControllerColliderHit(hit: ControllerColliderHit)
{
    if(hit.collider.gameObject.tag == "health")
    {
        Destroy(GameObject.Find("health"));
        Destroy(hit.gameObject);
        GRENADE_AMMO += 25;
        //GameObject.Find("g_count").guiText.text=""+GRENADE_AMMO;
    }
}

I tried attaching THIS to the health prefab but it wont even detect the collision:

function OnCollisionEnter(collision : Collision) 
{
    if(collision.collider.gameObject.tag == "Player")
    {
        Debug.Log("hit health");
    }
}

You don't need to use GameObject.Find() to look for the instance that you've hit - hit.gameObject does this.

I can't see why 'all the health instances' would be getting destroyed; this code should work:

function OnControllerColliderHit(hit: ControllerColliderHit)
{
    if( hit.gameObject.tag == "health" )
    {
        Destroy(hit.gameObject);
        GRENADE_AMMO += 25;
        //GameObject.Find("g_count").guiText.text=""+GRENADE_AMMO;
    }
}

If it doesn't, could you please post any other relevant code? Cheers.

This topic is kinda old but i would use

function OnTriggerEnter(other : collider){
if(other.tag == "health"){
Destroy(other.gameObject);
}
}

Hope it helps.
