How do I repair a corrupted project file with the error "cannot find behavior type 'Pin'"?

  • I have a folder-based project that has gone corrupt for some unknown reason. Not sure how or when, unfortunately - it's a bit old, and C3 projects seem prone to becoming corrupted for whatever reason. For all I know the original cause of the corruption has now been fixed.

    Edit: I made the mistake of trying to open an unzipped .c3p file as a folder-based project. Zipping it back up and changing the extension to .c3p allowed it to be opened.

    The console error is this:

    main.js:895 [Project] Exception opening: Error: cannot find behavior type 'Pin'

    at d.V4b (projectResources.js:827:276)

    at d.Ha (projectResources.js:885:79)

    at d.p3b (projectResources.js:1425:11)

    at async Promise.all (/r361/index 0)

    at async d.ovb (projectResources.js:1380:427)

    at async d.PLc (projectResources.js:1378:315)

    at async Promise.all (/r361/index 1)

    at async d.knc (projectResources.js:1855:439)

    at async zpa (main.js:896:412)

    Can anyone suggest how I might repair this? I wasn't using source control for this particular project because it was a bit of a throwaway anyway, but I'd still like to take a look at it if it can be recovered.

  • You are opening it in the new beta version of Construct3 r361.

    Try older versions using this link, which looks like this.

    editor.construct.net/r350

    editor.construct.net/r340

    editor.construct.net/r***

    If it opens, you can save it to a "*.c3p" file and open it in the new version.

  • Thanks for the suggestion, but sadly no luck opening it with older versions either. I think my poor project is history. It's not a big loss, but I think I'll take this as a sign and move on for awhile.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads
  • You can open project.c3proj file in Notepad and check which version it was saved in, for example:

    "savedWithRelease": 22500

    Then try to open the project in that C3 release, in the example above it's r225.

    If it opens, find the Pin behavior and remove it.

  • Thanks for the helpful suggestion - as it turns out, compressing it to a zip and then renaming the extension to .c3p allowed me to reopen it, which absolutely screams user error on my part (I assume I unzipped it at some point for some reason - it's a very old project.) Well, it wouldn't be the first time I have committed libel against Scirra... I'm just going to go correct my original post now... thanks for the suggestions, folks.
