No,
storyboard. If the iPad is detected it switches to the iPad version So I have two lua files for each scene. Universal apps.
In the beginning I experimented with doing the switch in one file, but the code became to long and hard to read. It was just easier to copy the code to a new iPad only file.
A lot of the coordinates and motions I had in my code did not translate easily to the iPad. I use a lot of images that need to be on a specific place and can;t be done with a simple relative placement.
So I got used to doing it in a code-iPone.lua and code-iPad.lua.
For this specific app I can convert the iPhone version by just adding +35 to the x and 130 to the y coordinates.
And multiplying the images by two. So I could have done that in one file. But I found out after I had already made the iPhone file.
