How to read keyboard input?

Chantcd_com · 08-06-2008, 10:54 PM

(I just found this sub-forum...sorry about posting it in the main Flash/Actionscript forum...)

My program starts out this way:

Code:

    public class MyProgram extends UIComponent 
{

...

Now I heard that any UIComponent registers keyDownHandler automatically, so you just need to override that function.

But although I get no errors, there is NO sign of life as far as keyboard input goes. I programmed the keys to do some drastic things (not shown below) but nothing ever happened. So I'm wondering what I'm doing wrong.

Code:

		override protected function keyDownHandler(e:KeyboardEvent):void {
		        if (e.keyCode == Keyboard.LEFT) {
		              trace("LEFT");
		        }
		        if (e.keyCode == Keyboard.UP) {
		              trace("UP");
		        }
		        if (e.keyCode == Keyboard.DOWN) {
		              trace("DOWN");
		        }
		        if (e.keyCode == Keyboard.RIGHT) {
		              trace("RIGHT");
		        }
		        
		}

Any help would be much appreciated.

Thanks,

Matthew

I'm not 100% sure but I've had the same problem, by default I think what the problem is unless you've used your mouse to click on that object that object won't detect the keyboard events. I noticed this when I first used a tilelist, then I noticed this when using a circle shape in AS3.
