I'm a programmer and I've been modding 1.13.1. The mod file works and double jump (server side) works properly, but I don't know how to make the launcher accept the .json file. Anyone help?
I've also made an installer for the mod, but the .json file doesn't work... You can find it here...
Also this is a new account, my previous account got lost... I'm ashdjtgfoe and I created Ashmod Collections, you can look my website up on google if you want. I made mods for 1.11.2 when it came out.
How, may i ask, are you modding 1.13? There is no forge release for it yet.
