Restart Problem

Questions & Answers

Hi! I added a pause menu script and when I click restart everything freezes (except that you can look around). Here is the script:

var skin:GUISkin;
var levelToLoad : String;
 
private var gldepth = -0.5;
private var startTime = 0.1;
 
var mat:Material;
 
private var tris = 0;
private var verts = 0;
private var savedTimeScale:float;
private var pauseFilter;
 
private var showfps:boolean;
private var showtris:boolean;
private var showvtx:boolean;
private var showfpsgraph:boolean;
 
var lowFPSColor = Color.red;
var highFPSColor = Color.green;
 
var lowFPS = 30;
var highFPS = 50;
 
var start:GameObject;
 
var url = "unity.html";
 
var statColor:Color = Color.yellow;

        {

There isn’t mush to go on here but I’m guessing that when you press pause, Time.timeScale is set to 0, meaning anything relying on deltaTime will not work.

When you press restart, you are probably forgetting to reset Time.timeScale.
