yield hangs from OnClick()

[wilmerlin]

I was trying to setup a script on a UIButton to load a level. It worked fine until I decided that I needed to pause the load of the new level with a yield.  The CoRoutine gets called but it does not yield and instead just hangs.

It works fine if I remove the yield WaitForSeconds(delay) or set the delay to 0.  Can I not call a Coroutine from OnClick()?



 

1.  
2. var levelToLoad: int = 0;
3. var delay: float = 1;
4.  
5. function OnClick() {
6.         yield LoadLevelWithDelay();
7. }
8.  
9. function LoadLevelWithDelay() {
10.         yield WaitForSeconds(delay);
11.         Application.LoadLevel(levelToLoad);    
12. }
13.

NGUI has a script for this: LoadLevelOnClick.

It does, but can I insert a yield WaitForSeconds() in there before the Application.LoadLevel?   Or does it not work because of OnClick()?

My own function works until I attempt the yield.  I can work around this by marking a time to load and loading the level in Update() but I thought this might have been the cleaner way to do it.

Nevermind. I am a friggin' idiot.  Have the time scale set to 0 because the game is paused.  Doh.

I have just spent 2 days banging my head against the coding wall with exactly the same problem, glad I found your post and suddenly realized I was doing exactly the same as you!
