Looping scene2d Actor actions

[Chuck]

I have an actor that needs to run a series of actions continuously in a loop. I'm wondering if this tail-recursive idiom is the best way to go about it, or if there's a higher level API that I'm missing out on:

Code: Select all

void animation(Actor a) {
  a.addAction(sequence(
        moveBy(x,y,t),
        delay(d),
        moveTo(x2,t2,t),
        ...
        run(new Runnable() { public void run() { animation(a) }})
   ));
}


Any advice?

Erm, how long is this animation running for? That code works, however it will end up creating a new animation object everytime it loops, which can be a problem if you are trying to deploy to phones or devices with lower amounts of ram.
After looking at the java docs, it does appear as if a looping action exists, here - http://libgdx.badlogicgames.com/nightli ... ction.html

There's a RepeatAction that you can set to run forever... I haven't used the new Scene2d package yet so I couldn't say from experience. Previously there was a Forever action if I remember right.

Edit: Varriount already linked to it.

It's running as a desktop application on a fairly beefy machine. I had 10,000 of those loops going full blast for about a half hour and it was still running a smooth 60fps, so it doesn't appear to be a problem, but my concern was forward-looking for Android and its less than stellar gc, yes.

Thanks for the pointer to RepeatAction. Looks like there's a Actions.forever() convenience method I somehow missed the first time around, and it looks like just what I needed.
