The Document Class:

 

package {
import flash.display.MovieClip;
public class DocumentClass extends MovieClip {
	public var playScreen:SpaceTowers;
	public function DocumentClass() {
		playScreen = new SpaceTowers();
		playScreen.x = 0;
		playScreen.y = 0;
		addChild( playScreen );
	}
}
}

 

Problem:

After pressing any arrow key, the game stops responding to key input. Wtf?

 

Ideas?

[Castiel]

Works for me..

                public function onKeyRelease( keyboardEvent:KeyboardEvent ):void {
		if ( keyboardEvent.keyCode == Keyboard.DOWN ) {
			...
		}
	}//onKeyRelease

 

Why is everything enclosed in that? What you're basically doing is saying "If the event is a DOWN key release, check if the event is a LEFT/RIGHT/UP/DOWN key release." What ends up happening is that none of the keys (except for down) are released, so once they are activated they stay in the true state. (Even though DOWN can be set to true, I think your UP key higher priority, so your ship keeps moving forward even if down is true.)

 

I'd imagine this would work:

 

		public function onKeyRelease( keyboardEvent:KeyboardEvent ):void {
		if ( keyboardEvent.keyCode == Keyboard.DOWN ) {
			downKeyIsBeingPressed = false;

		} else if ( keyboardEvent.keyCode == Keyboard.UP ) {
			upKeyIsBeingPressed = false;
		} else if ( keyboardEvent.keyCode == Keyboard.LEFT ) {
			leftKeyIsBeingPressed = false;
		} else if ( keyboardEvent.keyCode == Keyboard.RIGHT ) {
			rightKeyIsBeingPressed = false;
		}
               }

Oh my god KScrop,

[mapper]

Hehe AS3.0 is so much harder than 2.0

Hehe AS3.0 is so much harder than 2.0

 

Agreed, I'm pretty fucking confused.

I figured it was some wort of a copy paste error. For some reason it's always the dumb mistakes that are hardest to find.
