Hi,
I have imported the module in my game. Then, in the room I want parallax objects, I have put my backgrounds objects, and click on "properties" in the first one.
I have created the property "PxPos - number - default value 0".
Then I choosed for each objects -1, -2 or -3, depending of the distance.
I have add "ParallaxOn()" in the "before fade in" script, and "ParallaxOff()" in the "player leaves room" script.
But when I run the game, I have this error message :

I have 14 objects and they are animated, is that a problem ?
Please help !
