Tool to convert resource packs from 1.6-1.19, and vice versa
You can simply go to the releases and select any version you would like.
You put all the important files in the assets folder, theres a main minecraft directory which you can put all default textures (like blocks, items) and support for extra folders other than the main minecraft one (for custom textures you dont want to put in the minecraft directory).
There's 2 ways to run it, with the run.bat file alocated with the zip file in releases, or by running java -jar PackBuilder.jar in any terminal.
Sometimes I might have made a spelling mistake, if you see any file that didn't convert correctly, create an issue and It might be fixed soon.
I am working on this alone, and the current method is not the best, so i'd recommend people who want to create a branch/fork, create a pull request and, depending on the updates i might accept.
