Hi, as I said in my previous question, I'm new to Unity. I'm making a slender rip-off (yes, antoher slender question). I'm having trouble to make a bar that displays how much battery is left on the flashlight. I have an indicator, but it is in numbers so I want it to be a bar muck like a health bar

If anyone's interested, here's the script for the battery indicator I have at the moment:

pragma strict

//Makes you write with stricter formatting, which in turn increases the efficiency of the script

//Batteries

var batteries : int = 0;

//How much charge per battery

var charge : float = 100;

private var chargeDisp : float = 1;

/*^^ this is just used to display the variable through GUI.Label -- when a (Long) variable changes

many times, very fast, unity cannot keep up with redrawing the variable at that speed,

and so the text flashes. I don't like the look of it. This converts it down

a couple of decimal places, which makes it easier on the engine. I like how it looks at 2

decimal places. Convert it to 1, for no decimal places, and 100 for two decimal places.

1 is the number, 0 is a decimal place*/

//The actual torchlight object

var torch : Light;

//Speed at which the light decreases

var speed : float = 1;

//Used to turn light on or off

private var lightState : boolean = false;

function Awake() //Called before anything in a script, even called before start

{

torch.intensity = 1.85; //Set the intensity to 1 (1 is defined as 100 charge)

}

function Update ()

{

 chargeDisp = Mathf.Round(charge * 100) / 100; //See line under variable declaration

 

 if(lightState && charge > 0) //If mouse has been pressed, and there is still charge in the battery

 {

     torch.enabled = true; //Turn on the torch

     charge -= Time.deltaTime * speed; //Decrease the charge

 } else { //If one of the terms has not been met (IE, mouse isn't pressed or there is no charge

     torch.enabled = false; //Turn the torch off

 }

 

 if(charge <= 0 && batteries > 0) //If charge is less or equal to 0, and if batteries is above 0

 {

 batteries = batteries -1; //Take on from the batteries

 lightState = !lightState; //Toggle lightState

 charge = 100; //Charge equals 100 (This simulates putting another battery in the torch. 1 less battery, full charge

 }

 

 if(batteries == 0) //If there is no batteries

 {

 charge = 0; //There is no charge. This stops 'Batteries 1', 'Charge 100' from happening

 }

 

 if(Input.GetMouseButtonDown(1)) //Called when the mouse right click is down

 {

     lightState = !lightState; //Toggle lightState

 }

 

 if(charge < 4) //If charge is less than 5

 {

     torch.intensity = charge; //The torches intensity equals its charge. This makes the torch brighter, but then it fades out pretty quickly

 }

}

function OnGUI()

{

 GUI.backgroundColor = Color.green;
 GUI.Button (Rect (10, 10, 100, 20), "Bateria:" + chargeDisp ); //Display for charge. 

}

Could you guys help me?
