You can get the same effect without the warmup time by just positioning the tiledBg's in you layout and setting their speed. Then replace all your events with one every tick event:
Every tick
set x to self.x%50-50
Change the 50s to whatever the texture width is.
Ive been doing this, but i find that the width/height of the texture doesnt work, just some obscure number i have to take a long time guessing (im sure its related somehow, any idea?)
Here for instance. im doing it with height instead of width and the only number that works seemlessly is 130, which doesnt seem to have anything to do with the height. ?
Here is the capx
thanks for your time.
