Hey i am 12 and making my 2d platform game. I have managed to get it working except that lines appear in the tiles when moving.

here is. screen shot. i guess its something basic but i just cant seem to work it out.

ok so worked it out it seems that there is a one-pixel space a the end of each tile. so I set pixel per nit from 32 to 31 and it works perectly.
