Hi all, im trying to capture keyboard events to steer my ship. I’m getting no errors but my ship wont go. the key trace and the burn trace works.

> var lForce:Number;  
> stage.addEventListener(KeyboardEvent.KEY\_DOWN,moveShip);

ship\_mc.EnterFrame = function()  
{  
this.\_x +=Number(rForce)-Number(lForce);  
this.\_y +=gravityConstant -Number(uForce);  
}

function moveShip(evt:KeyboardEvent):void  
{  
switch (evt.keyCode)  
{  
case Keyboard.UP:  
uForce ++;  
burn();  
break;

```
            case Keyboard.LEFT:
                lForce ++;
                burn();
                break;

            case Keyboard.RIGHT:
                rForce++;
                burn();
                break;
            default:
                trace("keyCode:",evt.keyCode);
        }
    

}

```

function burn():void  
{  
trace(“burn”)  
}
