This is the method i am using right now to scroll the background:

+ Code Snippet

controls:
if rightkey()=1
  for sp=1 to 50
    if sprite exist(sp)=1
      if sprite image(sp)<>4
       OFFSET SPRITE sp, sprite offset x(sp)+10, 0
      endif
    endif
  next x
endif
if leftkey()=1
  for sp=1 to 50
    if sprite exist(sp)=1
      if sprite image(sp)<>4
       OFFSET SPRITE  sp, sprite offset x(sp)-10, 0
      endif
    endif
  next x
endif
return

but it is extremely choppy on my slow comp. So I was thinking doing the textured plain method...but then how could i do collision between objects if the sprites are not seperated?

Can someone please help me? I dont ususally do 2D games.

Thanks,

You divide the screen into squares....maybe 32*32. Then you scroll the screen, and keep a track of where the squares have now scrolled to.

dim map(Total Length of scrolling background/32, Height/32)

Then put a 1 in those dims for a collision, and a 0 for an area with no collision.

Just a matter of making sure that the dims are matched perfectly to the sprite position.

would that work pincho if you where using dots as your background you know

for s= 1 to 10000
Dot rnd(1024),rnd(1024)
next s

or would you need to use a image as your background?
