I am trying to move a sprite and unless I use 0.51 or greater it will not move. If I use x# = .25 it just sit's there. Then when I goto .51 I think It rounds it up to 1 and moves the sprite. Anybody know what I might be doing wrong.



Thanks

Are you using the percentage system or the virutal resolution system. Using decimals for positioning sprites in the percentage system should be fine but in the virutal resolution system it may get rounded off since you can't physically position a sprite at a fraction of a pixel.

Looking at your code however, in theory that should work, even if it is rounded off, it should move. Are you using it in a loop with the sync() command? A better question maybe is it being executed inside a loop?

Yes, there just isn't enough code there to make a judgement. Perhaps you could show us some more as it could be anything from not updating the screen to applying the position command to a badly typed variable.

We all make silly mistakes (me as many as anyone else)

One of the well established traditions on the TGC forums is to try to replicate the problem using code anyone here can compile and run. Normally (9/10 times) this resolves the issue before it even hits the forums as you find the problem before someone has a chance to say "You spelled 'HappySouth' wrong!" or something similar.

Sounds to me as though you have x# defined as an integer and not a float... Change #x to a float and it should move with increments of 0.25
