Can anyone tell me why the codes are not working for that part?
It supposed to increase/decrease the X or Y when the specific direction keys are press but it is not working now.
Thanks alot. :)

I dont know which codes to use for that method, so someone please guide me along for the bold ones

[helios]

???
For what part?
[code][/code] tags, please.

[Umz]

Code without the tags is really ugly.

I assume your referring to the part that has been commented out; is it giving you an error or is it simply not doing what your asking?
