At another thread there is an attachment that contains a fixed AMOS.library that fixes the dual-playfield bug.  Read that thread if you're having trouble scrolling things (see link above).

Also, if you're looking for an example of how to do parallax scrolling, a good example is here.  (Luckily this example doesn't get hit by the bug since the front playfield has all even coordinates.)

Thanks Samuraicrow Very Good now about the issues , I still cant understand rigth the way of the Colours 0 to 7 for screen 0 and 7 to 14 to the screen 1.... but now I can continue playing with the playfield.

other cuestion the maximun Screen I can open in Amos is 1020 pixel heigth (X Side) is any way to for example open a Screen with 2000 or 3000 pixel (X side)??

Thanks Again!  here is the new code of my parallax demo now much better :)

The second screen uses colors 8 to 15 with 8 being transparent.

The 1024 pixel limitation in the X coordinate is a hard-coded limitation in the original chipset and Kickstart 1.3.  That will have to wait until the next version of AmosPro is completed since AGA and ECS support won't be added until then.
