Cap Framerate in the asynchronous world of Javascript

Question

I'm developing a game in JavaScript & HTML5 with CreateJS. (I doubt you'll need CreateJS experience to answer this question, though)

My main game loop function is initialized and run using the CreateJS library like so:

createjs.Ticker.on("tick", loop);

(Similar to an event handler)

Then, it's off to the races - my function loops indefinitely, running my game at around 50FPS.

I want to cap this at 30FPS. But without a "sleep" function, or any real "pause" function, what's the best way to do that? How can I force my loop to slow down?

Thanks! -W

Answer 1

From the documentation:

Ticker.framerate = 30;

Hope that helps.
