Hey together. I really would love to make a Translation for the game 灵墟. Sadly im not a coding Pro like you guys and have no clue how to tackle the error in the Log :( Pls send Help :D Thank you in advance :) Btw Autotranslator works and loads and even translate things like the loading screen message but not more :(

[ManlyMarco]

The game comes with the encode to png function stripped out it looks like, not much you can do about that. One workaround would be to manually dump the images but that's a lot more advanced since you also need to figure out the names and hashes.

Thank you for your answer :) This is the seconde game i had interest in translating and seconde game where i get stopped by difficult stuff :D Is there a way you can explain me (in a language for toddlers) how to go about your workaround or is it way too timeconsuming and difficult to do it?

In short, you need to use something like AssetBundleExtractor to get the images out while retaining their original names, then use XUnity.TextureHashGenerator (it's in this repository but you have to build it yourself) on those images to generate the full names with hashes that can then be loaded by the plugin. Afterwards it's the same as translating a normal game. If you never actually translated textures in a game then it'd be best to get a feel for it in a game where it works first.
