Character Selector 

Character Selector is an RPG mod that allows you to create multiple characters for your world or server. You can have your main character (whatever your Minecraft name is), plus four more that you can name yourself to keep track of. Each character will have their own inventories, locations, advancements & more.

Mod Compatibility

I'm not sure what mods  are immediately compatible with Character Selector, anything that requires UUIDs or maybe the name of the player will probably need some compatibility built into it. Beyond that things should be compatible but let me know on discord or in the comments if you come across anything incompatible!

How do I use this?

It's fairly easy to use, you'll just create a world or join a server like you're use to, and as you're joining the world or server, you will be prompted to select a character. You will have your default character which will just be whatever your MC name is, or you can choose to create a new one and you will proceed to join with that character. There is also a defined character limit that is configurable, it's currently set to 4. You can have 4 extra characters and if you attempt to make anymore after that, the join process will be stopped and you can re-attempt to join. In that scenario you'd just pick one of your characters.

Developers

In the scenario your mod isn't compatible, I have two classes that can be used, CharacterSelectorAPI and CharacterSelectorClientAPI to grab the character that the player is currently using. After that you can use the UUID/Name of that character in any data that you need to.
