How to delay a function (how to use WaitForSeconds() and yield)
I know this has been asked before, but it just doesn't work, and I don't see what I'm dooing wrong.
(I use javascript)
function Quit (score:int) //quits to main menu (scene) { if (currentLevel>0) scores[currentLevel-1] = Mathf.Max(scores[currentLevel-1],score); currentLevel=0; //Application.LoadLevel(currentLevel); LoadCurrentLevel(); }
function LoadCurrentLevel() //is een coroutine (blijkbaar automatisch ofzo doordat er yield instaat ? { yield WaitForSeconds (2); Application.LoadLevel(currentLevel); }
I've read the documentation and I thought this would work, but it seems to wait for ever (instead of 2 seconds), Application.LoadLevel(currentLevel) is never executed.
don't know if it could be relevant, but this code is not part of a script attached to a gameobject (and it's a singleton).
EDIT:
I tried it differently now, like this:
function LoadCurrentLevel(wait:boolean) { //if (wait) yield WaitForSeconds (2.5); //Application.LoadLevel(currentLevel); if (wait) { isWaiting=true; waitingStart=Time.time; } else Application.LoadLevel(currentLevel); }
function Update()
{
if (isWaiting)
{
if (Time.time>waitingStart+2.5)
{
isWaiting=false;
Application.LoadLevel(currentLevel);
}
}
}
But it still doesn't work, it does exactly the same. why is that ?
Your script is correct. You need to attach your script to a GameObject.
What I do is create an Empty GameObject for all my games, and call it 'GameManager'.
Any game-wide scripts are then attached to that game object.
is there a way without attaching it to a GameObject ? it's just a lot cleaner without
(also, I would have to rewrite all the singleton stuff, so it works with the gameobject and it doesn't get deleted when switching levels ...)
As far as I know it needs to be attached to a GameObject. There is nothing messy about having a GameObject to manage all your global game logic. I find it very clean and efficient.
ok but I still don't get at all why my 2nd approach doesn't work. (the messy thing is that I have to create a gameobject at the beginning of the game and make sure it never gets deleted and is accessable from everywhere)
DontDestroyOnLoad(this.gameObject); will make any object a script is attached to be a perm. resident of your game world even on scene changes. The easiest approach is to create one at the beginning map, tag it with a unique tag to retrieve the object easily and then use its script.
