CJs Mod API
I don't know my version or loader
📖 What's this Plugin?
This plugin is an API I developed for mods in PaperMC, as I haven’t come across any alternative plugins that allow coding.
✅ Features:
- Custom Items
- Registries (for anything)
📖 Usage
Using the API is rather simple, it's kind of like making a Mod.
Though it's not, just lots and lots of abstraction making it easier ^^
For applied examples, look into Example Mod Plugin
📖 How Can I Add My Assets?
I recommend using Dynamic RP, as it's simple to use and specifically designed by me for this purpose.
📖 Where Can I View My Added Items?
To view your added items, type /modapi items in the chat. This will display all available ItemGroups. Click on your ItemGroup and see the items you’ve added to it.
