AS3 KeyboardEvent

By Tommy Leung on 08/02/2008 in Games

I’ve been working with ActionScript 3 a little bit more as of late and one rather confusing problem that seems to come up often is one with KeyboardEvent–it doesn’t seem to always work. The solution that I’ve come up with is to always add the KeyboardEvent listener to the stage of the root.

So, you will want to use addEventListener in the main class:

stage.addEventListener(KeyboardEvent.KEY_DOWN, KeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, KeyUp);

And that’s it! This way has worked well for me so far. I actually use a KeyManager class to initialize the events and the stage is passed to that class.
