Betty, 1. Two backgrounds as Sprites. Each center is x=0,y=0 as expected 2. frame is 480 pixels wide. 3. start frame 1 at x=0 and frame t2 at x = 480 (off the screen) 4. Start moving both in repeat 480 loop by -1 each pass in forever loop 5. At he end of the 480 loop (use space variable set in background script) set center of frame 1 to x = 480 and frame 2 to x= 0
Try setting space variable to other numbers, say, 460 which gives an overlap.
