Changing the size of a ball, problems with transform.localScale

Questions & Answers
1

I’m trying to make it so the player object, a ball, decreases in size as a timer goes down. It’s supposed to be like a snowball melting. I’ve made a variable to represent the ball’s size so it can change as the timer changes. I’ve tried using transform.localScale a few different ways but the ball is always increasing in size rapidly instead of decreasing slowly. I’ve been trying to avoid posting it on here because I’m a newbie developer and I wanted to try and figure it out on my own. But I’m stuck on this. Any help would be greatly appreciated.

#pragma strict

var maxFallDistance : int = -10;
var ballSize:int;
var timer : float = 10.0;

function Update () {

	if (transform.position.y <= maxFallDistance){
		Application.LoadLevel ("Tutorial");
	}
	
	ballSize = timer; 
	Debug.Log (ballSize);
	
	timer -= Time.deltaTime;
	if(timer <= 0){
		timer = 0;
	}
	
	transform.localScale += new Vector3(ballSize,ballSize,ballSize);
}

function OnGUI(){

	GUI.Box(new Rect(10,10,50,20), "" + timer.ToString("0"));
}

Also please don’t refer me to Unity - Scripting API: Transform.localScale. I tried it and tweaked it a bunch of ways but it kept making it bigger.

Thanks guys

You’re using += to change the scale, this adds to what is already there. If you start with scale of <1,1,1> and use that with ballSize 0.9, you end up with <1.9, 1.9, 1.9>. You want to use = to assign a new value instead.

transform.localScale = new Vector3(ballSize,ballSize,ballSize);
