How do i do that?

[ZulfadlyAshBurn]

I am creating a game and i need the WASD to work with my code. I have done the keymapping and its working. but how to i actually minus one from the variable. example is the current img position top is at 100 the when i click W is will be 99.

 

 

 

<script>
shortcut.add("W",function() {
var obj = document.getElementById('div1').style; 
obj.top -= 1;
});
</script>

 

 

this doesnt seem to be working. I need help...

obj.top is "1px", you have to parse the int using parseInt(obj.top, 10).

thanks. i used

 obj.top = parseInt(obj.top)+20;

and it works
