So this is probably not hard for someone who is above average iq. The thing is that I'm trying to make a flip through introduction start page, but I'm having problem with the mask. I have try to use canvas but when it loads my game it mess it up, so I just used layer to do a masking effect. The problem is I can't figure out how to do it correctly because I have layers, like can you move a layer and where is that command. I was looking for the System scroll to position layer and I can chose a layer kinda thing. I need it because my game window size is a lot bigger than the introduction.
