health bar referencing another scripts variable

Questions & Answers
1

This is the health script that Im using.

var health : playerhealth = gameObject.GetComponent(playerhealth);




var initialGreenLength: float;
var greenBar: GameObject;
var helth: int = health.HP;
var maxHealth: float=100;
 
function Awake(){
helth=maxHealth;
initialGreenLength=greenBar.transform.localScale.x;
}
 
function Update(){
greenBar.transform.localScale.x=initialGreenLength*(helth/maxHealth);
 
}

The

var health : playerhealth = gameObject.GetComponent(playerhealth);

section of the script references another scripts variable of player HP, but it doesn’t seem to be working. This is the other script

var HP : int = 5;
var body = gameObject;

function Update () {

	if(HP < 1) {
		
		var instance : GameObject = Instantiate(body, transform.position, transform.rotation);
		DestroyObject (gameObject);
	}
}

How do I fix it so it works?

var health : playerhealth = gameObject.GetComponent(playerhealth);

should be:
var health : int = gameObject.GetComponent(playerhealth).HP;

If I understand you correctly, also “playerhealth” needs to be the ‘destroy’ scripts name

I figured out how to fix it, I deleted the HP bar script, made a GUIText, and changed the player health script to look like this,

var gui : GUIText = gameObject.GetComponent(GUIText);
var HP : int = 5;
var body = gameObject;

function Update () {
	
	gui.text = "Health: "+HP;
	
	if(HP < 1) {
		
		var instance : GameObject = Instantiate(body, transform.position, transform.rotation);
		DestroyObject (gameObject);
	}
}

thanks everyone for the help though.

This probably happened because Helth or MaxHealth was == 0. One rule in math: You cannot divide by 0. If you do something like:

(Helth + 0.0001)/(MaxHealth + 0.0001); You would be good (add the 0.001 to whatever could potentially be 0).
