About this project
What does ChemLib Custom Compounds add?
This mod is a small addon for the ChemLib mod and allows modpack creators to add their own elements and compounds to the mod using only JSON configuration files which is a lot more lightweight than using somethingn like KubeJS.
This mod does not currently allow removing existing elements or compounds. If you require this feature, please open an issue and i'll see what i can do.
Your custom configuration can be added as config/chemlibcc/elements.json and config/chemlibcc/compounds.json. The format is the same as used by the mod itself, except there's an additional display_name property for every entry to faciliate translations.
A custom compound configuration might look like the following:
