Making the up and down sprite not move until able

[Poyzin]

I don't know how to code very well..more of adding stuff from stuff thats there..like text and colours and stuff..but not really at this kind of stuff..

I found some codes for the movement

what would i do,
like eh

if i created vb. it would probably be the code:
If DIR_UP = No movement Then
Disable DIR_UP sprite
End If


lol..shows how much I know

do u think you might show me how to get started ^^ ?
