My bad, didn’t see that forward declaration. I just meant that global variables could potentially cause problems later in the game, not to mention some memory leak problems. I had the same issue so I just wanted to warn. I should have known you had caught it.
I don’t have my iDevice on me so I can’t test this out, but it looks normal to me. Also to confirm, you tried the distribution build on a device? Did you try running it with the XCode console window to confirm no errors are being thrown?
Wait so you mean I can install my distribution build through XCode? How do I do this? The XCode organizer does not let me add distribution provisioning profiles to my device, so when I try to install a distribution build, it just says a valid provisioning profile was not found.
Just to make it clear, when I say that my distribution build is wonky, I mean the version of the app that I download from the App Store.
Here is the link on how to run the XCode simulator on Macs to evaluate error logging:
http://www.coronalabs.com/blog/2013/07/09/tutorial-basic-debugging/
As far as not being able to put your distribution build onto your device from XCode, I’m not sure where you’re going wrong there, but I can do it with my setup. I followed the below link when I set up my configuration and it works perfectly:
http://developer.coronalabs.com/forum/2012/01/10/ios-walkthrough-testing-device-0
Oh you mean to create an ad hoc profile. Okay, I just tested it now and I can confirm that the bug appears when I build for my device using a distribution profile. Without changing a line of code, it works fine when I build for development. And nothing strange is showing up in the console.
Edit: I think the issue may have to do with admob. Investigating now.
Curiouser and curiouser. I’d suggest manually niling the objects when you leave the scene and see if that allows them to disappear?
My mistake, it turns out there is an error showing up in the console. Looks like a gotoscene error. Removing admob doesn’t affect it, even though some admob warnings show up.

You’ve got yourself a filename error. Having spaces and periods in filenames usually throws errors when you get to a device, but everything works normally on a simulator. Weird that you weren’t getting errors when you installed with a development build. I’d suggest taking the spaces, uppercase letters and periods out of the actual lua modules and the text in your scenes, and try it out then.
So I changed all my lua files to lowercase with no spaces and periods and all my folders containing lua files to lowercase with no spaces and periods. Still getting the same error.
This is an example of the code causing the error:
storyboard.gotoScene( “menufiles.mapselection”, “fade”, 300 )
You still have a period in the filename up there. Did you try taking this out, and making sure it is identical to the lua filename itself?
mapselection is inside the menufiles folder. If I use a “/” instead of a period, Corona tells me to put a period in. I am going to try putting all the lua files in the main directory.
Snap, my bad. I’ve never stuck my lua modules in anything but the main root folder. I just tested the period with my stuff and it works fine on the simulator, but I haven’t tested it on device. Let me know how it turns out.
Huh still not working. And the funny thing is that there is one scene that seems to work fine.
So I’m currently looking at this scene which causes the error when I try to go to it.

Took me half the day but I fixed the problem. The problem was with one pesky png file. I was loading a bunch of images here:
And I found that the error was removed if I commented out this code. So I looked at the 10 png files I was loading and it struck me as odd that one of them was 500kb while the rest of them were <100kb. These images are images of maps that I created in Tiled Map Editor, and saved using “Save as image”. So I resaved this unusually large image and now it works.
Really appreciate your help. Now I realize why all lua files are in lowercase :blink:
Not a problem a’tall. If it’s any consolation, I’m going to be checking your game out when I get home.
I’m a big fan of those sprite assets. I saw them over at opengameart.org and wanted to implement them very badly!
Are you planning on releasing on Android?
Yep those assets are great, I came up with the idea for the game after I saw them. Will release on Android when I upgrade to Pro, but that might be awhile…wanna try out unity first.
