Question

Hey guys,

I currently have my gun setup in my FPS game so that the player can shoot, a muzzle flash occurs, and there is a blood particle system instantiated when the player shoots at the enemy. all I can't figure out now is how to take down the health variable of the enemy one by one each time the enemy is shot!!!!!

Here is my gun script!:

var hit : RaycastHit;
var bloodPrefab : GameObject;
var muzzlePoint : Transform;

function Update () {
    if(Input.GetButtonDown("Fire1")){
       StartCoroutine("Shoot");
    }

}

function Shoot(){
    var fwd = muzzlePoint.TransformDirection (Vector3.forward);
    if (Physics.Raycast (muzzlePoint.position, fwd, hit, 100)){
       if(hit.collider.gameObject.tag == "zombie"){
         Instantiate(bloodPrefab, hit.point, hit.transform.rotation);
       }
    }
}

That all works good!, but how would i take down the health of the enemy tagged "zombie" when it hits it. The zombie has a script on it called "zombie" and a health variable called "health" if that matters!

Thanks!

I suppose the easiest way would be to use SendMessage. Have a method in the Zombie's script that decreases it's health, and call it when the player hits.

if(hit.collider.gameObject.tag == "zombie")
{
    Instantiate(bloodPrefab, hit.point, hit.transform.rotation);
    hit.collider.gameObject.SendMessage("DecreaseHealth", amountOfHealthToDecrease);
}

Hey,

Thanks for your response, I noticed I could do it with GetComponent pretty much the same way you showed here, but by going:

hit.collider.GetComponent(zombie).health --;

Oh, of course, if the field is public. I presumed it was private for some reason. :P
