WaitForSeconds doesn t work?

Hi there.. I would like to start the animaton after 5 seconds, so I added "yield WaitForSeconds (5)", but If I add that line, the animation doesn't start anymore.. why?

Code (JavaScript):

1.  var Animazione = "Vagone";
2. var on : boolean;
3. function Update () {
4. if (Input.GetKey(KeyCode.Q)) {
5. on = !on;
6. if (!on){
7. yield WaitForSeconds (5);
8. GetComponent.<Animation>()[Animazione].speed = 0.5;
9. GetComponent.<Animation>().Play(Animazione);
10. }
11. if (on) {
12. }
13. }
14. }

 

That's not the right way to call it. See the official example.

 

Simply change:

Code (CSharp):

1. yield WaitForSeconds

with:

Code (CSharp):

1. yield return new WaitForSeconds

 

I changed It, but "yield return new WaitForSeconds (5);" give me the error: ';' expected. Insert a semicolon at the end.

 

So I cannot use this in my script, because It can be used only in coroutines?

 

You can't use yield in Update(), but you can start a coroutine that uses it from Update(), like in AngryAnt's example here: http://forum.unity3d.com/threads/waiting-for-seconds-in-update.19347/

 

Thank you
