Hi,

I was trying to run the 2nd part sample code from the AppGameKit link bellow:

http://www.appgamekit.com/bitesize-1.php

I don´t get a parallax effect to work, the sprites all move the same speed and not as in the description.

Is there any bug in the code?

Thanks

There is a bug in the code but there's a really easy fix. Simply add this:

x# = getSpriteXByOffset(spr)
y# = getSpriteYByOffset(spr)
setSpritePositionByOffset(spr,x#, y# )

in the main for loop after this:

Xoff# = -(d#-100.0)*0.01*vx#
Yoff# = -(d#-100.0)*0.01*vy#
setSpriteOffset(spr,Xoff#,Yoff#)

Basically what's happening is that the spriteOffsets are being adjusted but the sprites aren't being repositioned, so the offsets don't have any effect.
