GameMaker Studio 2 Export Broken With Recent GM Update #4132
Comments
These issues were not known until you reported them, so thank you for opening an issue about it! Unfortunately, I forgot to look into this before publishing the Tiled 1.11.1 release. I'll look into making the necessary updates. |

Alright, when opening my old test project in recent GameMaker it told me that it needed to be converted and it actually made a copy of the entire project to a new location of my choice. And at the new location, the files look different in subtle ways:
So far I fail to understand why these changes would require duplication and conversion of the entire project. Since the new fields appear to duplicate information, my guess is that it's some kind of optimization that wouldn't work if it wasn't applied everywhere. I hope I can adjust the format while staying compatible with older GameMaker versions. Since the old fields are still there I guess it might be compatible. |
It seems an update to GameMaker in late 2024 has broken compatibility in several ways: * It now requires a "type tag field" at the start of applicable JSON records. * The name is expected to follow the "type tag field" as a "%Name" field, in addition to the regular "name" field. * Except for these special properties, the JSON fields are now required to be ordered alphabetically. Other minor differences include: * The "tags" field is left out when there are no tags. * There is no longer a space included after JSON field names. * Some new fields were added. This patch does not address all alphabetical ordering issues. Propably the preferred way will be to collect the fields in a QJsonObject first and rely on automatic sorting of the fields while serializing. Closes mapeditor#4132

I've started to address the incompatibilities in #4142. It's not finished yet. Especially due to the required alphabetical sorting of the JSON fields, GameMaker is being incredibly picky now. |

Oh boy... I thought I had a clean solution to this by stuffing things in a map (or |

@DustinVG I think I've got it fully working again now. Please see if you can take the builds available from #4143 to test whether it works also in your case. The files will be available at https://github.com/mapeditor/tiled/actions/runs/12787726250. |
Besides the fact I had to delete a ton of old unused variables (which I probably should've done already anyway), yes, it appears to work fine. The only issue I'm running into is that Tiled doesn't seem to be setting the color variables in one of my objects properly where it previously did:
|
Is GM now complaining about these unused variables where it wasn't before? Do you think the exporter could be changed such that it won't complain about unused variables, or is the required cleanup a good thing?
Hmm, maybe something changed about the color values as well. I don't personally know GameMaker very well, so could you maybe help me by describing how you got these properties set up on the GameMaker side? |

@DustinVG I found the problem and fixed it in d7497ae. I think the colors you were seeing must have just been the defaults, because the properties set on the object were getting ignored due to that regression introduced along with the new Properties view. New build will be available at https://github.com/mapeditor/tiled/actions/runs/12816565529?pr=4143 |

Reposting here for maximum visibility
A recent GM update seems to have rendered maps exported from Tiled incompatible. Attempting to load the project in GM will result in an error reading
Adding this field manually will turn the error into
Adding that field turns it into
And so on and so forth.
I’m sure this is known and is being worked on, but I wanted to make absolutely sure. Thank you for your time.
