Sometimes the first SYNC doesn't quite work. Make your first SYNC right under the SYNC RATE command or put the sprite in a DO/LOOP so it SYNCs over and over again.



You should use .png for images instead of .bmp and never ever use .jpg (they change the colors around). .pngs allow you to use alpha channels so you can make transparent areas on the sprites.

The only time you use SET CURRENT BITMAP is if you use LOAD BITMAP with a number other than zero. Using just LOAD IMAGE you don't need to set the current bitmap since Darkbasic Pro starts at bitmap zero.
