Hi everyone,
I need your help. I'm trying to make a puzzle game which shows a 44 picture with 1 empty field. If you click on a neighboring tile, it will slide it to the empty space. Right now, I'm just using the tutorial field, trying to display a 320320 picture. It works, but a little part of the picture is shifted. Anyone knows why that could be?
Also, instead of painting the whole picture in one piece, I would like to make it in 16 parts(4*4), can anyone tell me a good way how to cut up the picture without putting up 16 pictures?
Thanks in advance!
