background image causing a crash

edited December 2013 in Bugs Posts: 116

I created a background image for a game I am working on and it was working perfectly.

I then went to test on an iPad once compiled with Xcode and it crashes.

so I change the simulator to use an iPad retina and the same error occurs.

It acts like the PNG is missing..

    This is a glitch in the Codea Runtime, it's an error on exporting in the current Codea version. Xcode can't find the background image, basically. You might need to manually put the background image in the Documents.spritepack folder in your Xcode project.

    I wouldn't recommend exporting a Codea project to Xcode until Codea updates. Codea doesn't currently officially support iOS 7 but it will in the next update. Exports are glitchy with iOS 7 when it was designed for iOS 6. Try waiting until the next Codea update, which hopefully won't be too long, to fix all these bugs.

    In the meantime, you need to manually move your background image to the Documents.spritepack folder in your Xcode project.

  • the images are in the folder. they just act like they are not. they even get copied to the simulator.

    Are they .jpg files?

  • PNG and they work on the ipad one. Just not retina.

  • @SkyTheCoder, they're .png's

    @wrmichael @CodeaNoob I thought they should be PNG too, but in Planetroids I was getting errors on not being able to find images, and found they had to be JPG. For some reason PNG works in Codea but not Xcode...

  • i need transparencies. can i do that with jpg?

    Not sure... I've been trying but couldn't get it to work.

    For what it's worth, I had no problem using PNG. Just make sure you register the images in XCode on the Summary screen.

    @Mark I think that was my problem. How do you register them?

  • or wich summary screen?

  • Posts: 1,254

    On the left column of XCode, give the project name a double click. On the Summary tab, scroll down to where the images are shown, click and select those you want to use (sorry, I'm sure these screens have specific names, but I'm away from my Mac).

  • under "Copy Bundle Resources" it has the SpritePacks folder but not the individual images.

    Maybe there is another list?

  • can it be something about the image? like resolution?

    I added the images after I created the project.

  • I pulled out the Xcode 4.6. It has the 6.0 and 6.1 simulators in it so I assume it is an XCODE 5.x issue. @simon I can test some beta updates if you have them.

  • I solved the issue. Not the way I want to solve it. It required I go into a blank a project in Codea, import the modified image I had and then export the project and copy the images from documents:sprites to my project for use.

    not perfect but it works.

  • This may already be solved by now, but I had the same issue and solved it by removing references to the the SpritePacks. Add them back by choosing "Add files" and select the sprite pack folder that you removed the references for. NOTE: make sure you change the option from "Create groups for any added folders" to "Create folder references for added folders". I compiled for iOS 7 and it appears to work well.
