Calling a function every 2 seconds.

Does anyone know a good way I can call a function every two seconds so I can control the speed at which I my Ball objects across the screen.

I already have a function to instantiate the objects I just need a way to call it at specified time intervals , is it possible to make these values a little varied using something like Random.Range?

 

what is it exactly that your ball is doing? Is it something bouncing around the screen?

 

You could do something like this:

Code (csharp):

1. private var gapTest = true;
2.  
3. function Update () {
4.     if (gapTest) {
5.         // do your stuff here option 1
6.         GapSet ();
7.     }
8. }
9.  
10. function GapSet () {
11.     gapTest = false;
12.     // do your stuff here option 2
13.     yield WaitForSeconds (2);
14.     gapTest = true;
15. }

 

InvokeRepeating("MyFunction", .01, 2.0);

Code (csharp):

1. function Start () {
2.     while (true) {
3.         yield WaitForSeconds(Random.Range(1.0, 2.0));
4.         // do something
5.     }
6. }

Thanks very much for the advice guys, I took it all on board and it seems to be working nicely

 

Eric, is there any reason you wouldn't simply do it like this..

Code (csharp):

1.  
2. function Start()
3. {
4.  gapSet();
5. }
6.  
7. function gapSet()
8. {
9.  while(true)
10.  {
11.  yield WaitForSeconds(Random.Range(1.0,2.0);
12.   // Do stuff
13.  }
14. }
15.  

While i'm sure the performance difference between the two isn't even measurable, I'm just curious as to why you've done it that way

 

Considering they are exactly the same, I'm sure too.

Takes less time to type, uses a few bytes less memory....

Just in case somebody comes to here since we have a beautiful function now in 2016:

That looks very similar to @Eric5h5's answer in this thread (made in 2010)

 

Holy Molly sorry yea it did exist since 2010... (i've been an dumbass for nearly 6 years...)

 

Well You can just invoke the function in Update method:

void Update ()
{
Invoke("Ball", 2f);
}

I didn't know what you function was called, so replace "Ball" with your function name.
