Saving json data to folders in resources or data directory

[patent pier]

Is it possible to write to json files to these directories at runtime? Is there any relevant documentation?

[quaint fog]

it is completly possible, tho there isn't much documentation about it. this article is from fabric's wiki: https://wiki.fabricmc.net/tutorial:custom_resources, but i would recommend checking other mods' source code and look at how the ydo this thing

wait i missed a little bit what you meant, sry. i believe it is possible, however i have never tried it before. it could be a little complicated because of writing and saving files so it probably should be thread safe. also minecraft doesn't reload its resources automaticaly, so if you want the game to access these files, you need to reload resources beforehand

do you know how i can programmatically get the folder path for the assets folder

[fresh burrow]

why? they're embedded into your mods jar after compilation

[patent pier]

I have a world preset you can customise in a similar fashion to flat world customisation

There are some inbuilt presets, like super flat, that are stored as json and loaded as a resource thingy

Wanted to add functionality for users to save their own presets

[patent pier]

This

In this case, you'd want to store a config file to hold your custom presets

[patent pier]

Are there docs for this?

[gusty girder]

nope. You are free to store/read the config file however you want

If you want to follow a doc, there are plenty of config mods to choose from

[patent pier]

Oh right, but where do I write them / read too is the main thing.

[fresh burrow]

fabric loader has a method for getting the config dir

you can just FabricLoader.getInstance().getConfigDir().resolve("mymod.json")

[patent pier]

Awesome I’ll check that out

[fresh burrow]

and the easiest way to serialize/deserialize it would be to just have a config class and using gson's serializer

https://github.com/dicedpixels/hardcover/blob/main/src/main/java/xyz/dicedpixels/hardcover/Config.java for example

[patent pier]

Could I put json files in the config directory and use the same codecs I’ve been using for the built in presets

[fresh burrow]

yes

https://github.com/Raik176/undertale-death-screen/blob/master/src/main/java/org/rhm/undertale_death_screen/Config.java for an example of a config using codecs

[patent pier]

Thanks

[patent pier]

Do you think i stick with resource loaders of for the built in presets or configs like this instead

[fresh burrow]

it depends, resource loaders only allow people to add stuff using datapacks and using a config doesn't require using datapacks

[patent pier]

I've got it working through a config, but now it hits me. Why do I need to do any of these presets through a custom resorucelistener (looking into assets/data folders)

is there any advantages to these locations over a config

Depends on the use case
