It's fine cause I've been just changing gamerules since my mod is only a fighting mod but how do I get it approved for real? I want to become a mod maker and it won't work in any multiplayer servers :C

You need to upload your mod here for it to work in multiplayer.

Im not 100% on this so dont quote me.
It needs to be original, and you need people to play it and say its worth being put in.
For other peoples opinion, send them the mod file. They can play it in single player.
