I currently ported a BB1 game I'm working on with another developer over to BB2. I am currently trying to make each scene a level but I keep on running into problems with the alignment. In the scene editor everything is ok but when I open the preview all the objects move to the right when I select the next scene in my level selector. We were not having this problem in BB1. I am currently using BB2.1 In Scene Editor In game preview
This probably has to do with the position of your character and the game frame. Possible it moved when porting to BB2?
