Answer 1

I've looked at your code and it looks fine to me, but why don't you try tracing and see what happens?

Answer 2

private var leftKeyIsDown:Boolean;
private var rightKeyIsdown:Boolean
private var downKeyIsDown:Boolean;
private var upKeyIsDown:Boolean;
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown); //when key is down, go to this function
stage.addEventListener(KeyboardEvent.KEY_UP, keyUp); //when key is up, go to this function
gameloop();
private function gameLoop(e:Event):void //this function runs 30 times every second, due to 30fps
{
playerControl();
}
private function keyDown(e:KeyboardEvent):void
{
//trace Event and KeyCode, when we trace this we get I.D number from key
//trace(e.keyCode);
if (e.keyCode == 37)
{
//left key is pressed
leftKeyIsDown = true;
}
if (e.keyCode == 38)
{
//up key is pressed
upKeyIsDown = true;
}
if (e.keyCode == 39)
{
//right key is pressed
rightKeyIsdown = true;
}
if (e.keyCode == 40)
{
//down key is pressed
downKeyIsDown = true;
}
}
private function keyUp(e:KeyboardEvent):void
{
//if our left key is released
if (e.keyCode == 37)
{
//left key is released
leftKeyIsDown = false;
}
if (e.keyCode == 38)
{
//up key is released
upKeyIsDown = false;
}
if (e.keyCode == 39)
{
//right key is released
rightKeyIsdown = false;
}
if (e.keyCode == 40)
{
//down key is released
downKeyIsDown = false;
}
}
private function playerControl():void
{
//if left is currently down
if (leftKeyIsDown)
{
//move ship to the left
ship.x -= 5; //subtract 5 from ships position evey loop,
}
//if right is currently down
if (rightKeyIsdown)
{
//move ship to the right
ship.x += 5; //subtract 5 from ships position evey loop,
}
//if up is currently down
if (upKeyIsDown)
{
//move ship up
ship.y -= 5; //subtract 5 from ships position evey loop,
}
//if left is currently down
if (downKeyIsDown)
{
//move ship down
ship.y += 5; //subtract 5 from ships position evey loop,
}
}
replace ship with your object.
This is a template, i've commented too.
Please tell me if this is useful, it doesn't fix your code, I know.
But hopefully you can adapt this to it.
