hi.. im noobs.. i also searching for this.. parallax effect controlled by accelerometer thingy...
i found simple solution.. (and noob)
for parallax going to work you need at least 3 photo.. (1 big background, middle photo, and foreground image)
you just need to create 3 symbols, and each inside of it you just add "Physics" full physics body. (symbols need so the image don't make collusion)
dont forget to add some "walls" (using 4 rectangle on left-right-top-bottom with 0 opacity) in each of the symbols.. ism.hype.zip (118.3 KB)
