I tried to make a bar that desreases automatically with a current time from 100% to 0%. The bar can increase with 50% if the player takes an object. And if the bar is 0%, you have to go to alternative scene. Someone who can help me out with. I’m really confused now. I’m working with JS.

Thanks in advance.

All you need to to add a timer:

```
#pragma strict

var totalTime = 5.0;
var remainingTime = 5.0;
var Bar:Texture2D;
var BarWidth:float=400;
var BarHeight:float=200;

function Update() {
	if (remainingTime > 0.0)
		remainingTime -= Time.deltaTime;
}
 
function OnGUI(){
    GUI.DrawTexture(Rect( (Screen.width - BarWidth)*0.5,(Screen.height - BarHeight)*0.5, BarWidth* remainingTime/totalTime, BarHeight), Bar);
}

```
