Failed to unmarshal type TileRenderMode

[sammysheardev]

Not sure what to do with this error. I figured I would try out ldtk for my newest game, but I can't seem to get it working because of this exception.

Hi, thanks for letting me know about this, I'll look into it. :)

What sort of steps did you take so that this happens? It is much appreciated If you can send me some reproduction steps. Also, see about sending me the entire error in the console log.

I created a new project in Ldtk, put it in the unity game's directory, created a new project asset, but it fails to set the project file field to the actual project file. If I'm missing something obvious please let me know! I have not checked with a different project file to see if I could reproduce it, but I might try that. The full error is a bit long, but here it is:

Just to confirm, this occurs when I try using the sample 2d platformer from Ldtk as well.

[sammysheardev]

Just a little addendum to the issue, when using any of the ldkt files from the samples for the package, it runs perfectly, which makes me think it's something wrong with the actual ldkt file. Is it possible it is a version conflict?

[Cammin]

Yeah, that's correct now that I think about it. LDtk version incompatibilities would be the reason. LDtk has been receiving plenty of updates with new types of values (particularly enums in this case), and the JSON deserializer may be trying to get a new enum value that was not set up for this package's version. A massive update is on its way that may fix this. Just making sure it's stable and works correctly. 👍

Tons of reworks for a simpler experience, cleanup, updated to newer ldtk project data, and the rework of building levels in edit mode instead of in runtime. The update should come pretty soon 😃

[Cammin]

I've seen this issue happen with someone else in the new major update. It's a Json deserialization issue, so I'll try updating the json schema files from 0.8.0 to 0.8.1

[Cammin]

Yes, it was a bug due to outdated JSON schema files. All good. Going forward, I'll try to update the JSON schema files ASAP when there is a new update to LDtk. 👍
