I have a tiled background and 2 sprites with physics.
I apply a force of X=100 to the sprites and set their "center on me" attribute in an unbound layer.
Every time ScrollX reaches 100 I set sprites X to sprites X - ScrollX and TiledBackground.X = TiledBackground.X - ScrollX.
For Tiles, no problems but the distance between the sprites is greater each time and I don't understand.
Here is the cap http://www.box.net/shared/xsj88ea2al
Please, help, I'm desesperate
