[Flash8] Key class problem with onKeyUp, multiple keys

programming flash
1

Hi there,

I have been playing around with the key class in flash as I want to use the keyboard to control a game. I noticed however that it seems to have problems with pressing of multiple keys. Using the code below do the following.

[LIST=1]
[]Press and hold the space bar(the onKeyPress event is continulously triggered)
[]Whilst that key is still held down press another key(triggers onKeyPress and onkeyUp)
[*]Now release the original key(Spacebar) and you will see that the onKeyUp event is not triggered.[/LIST]
Basically I want the user to be able to hold down a key to control movement whilst pressing other keys to shoot etc…

Any help would be appreciated :slight_smile:

here is the code…


var globalPressListener=new Object();
Key.addListener(globalPressListener);
globalPressListener.onKeyDown=handleKeyPress;
        
var globalReleaseListener=new Object();
Key.addListener(globalReleaseListener);
globalReleaseListener.onKeyUp=handleKeyUp;


//=====================================================
//=====================================================
function handleKeyPress(){
        var keyPressed:String=getKeyPressed();
        trace('keyPressed = '+keyPressed);
    }
    
//=====================================================
function handleKeyUp(){
        var keyReleased:String=getKeyPressed();
        trace('keyReleased = '+keyReleased);
}

//=====================================================
function getKeyPressed():String {
            var theKey:String;
            switch (Key.getCode()) {
                case Key.BACKSPACE :
                theKey = "BACKSPACE";
                break;
                case Key.SPACE :
                theKey = "SPACE";
                break;                
                case Key.LEFT :
                theKey = "LEFT";
                break;
                case Key.RIGHT :
                theKey = "RIGHT";
                break;
                case Key.UP :
                theKey = "UP";
                break;
                case Key.DOWN :
                theKey = "DOWN";
                break;
                default :
                theKey = String.fromCharCode(Key.getAscii());
            }
            return theKey;
}
