Been looking into this problem for a couple of days and cant seem to get it working.
I have a game with three layers running at different x coefficients to create a basic 3d effect and seem to have a issue when adding a ladder backdrop (with obstacle ladder).
It looks like it works fine when layer with the ladder is on the bottom of the layer list, however when the ladder obstacle is on the top layer it stops working (turning off physics for the player active fixes it).
I have attached a example with a empty layer to show the issue.
I am a bit of a noob (3 days of Snails tutorials, thanks snail ) so it's likely I am doing something silly .
Any help with the issue would be great
