About this Mod
This mod is in early stages and I still pretend to add much more content to it!
Note: This mod requires some knowledge how of datapack works!
Introduction
Have you ever thought about creating an RPG mod pack, but all RPG mods add generic skills and only allow for a few customizable settings?
Koko is a fully modular mod that allows you to create your own skills, their experience sources, and their effects on the player.
Let's look at an example:
You want to add the creativity skill to your mod pack. But you soon realize that none of the modern RPG mods include it.
Koko allows you to do this.
First, you need to download and install Koko. After that, create a datapack in the following path:
Now, simply create the .json file for your skill e.g "creativity.json":
This is the default pattern.
{
"display_name": "Creativity",
// This is a translable component!
"description": "Hi! I am creativity skill!",
// This is also a translable component too!
"icon": "lantern",
// This must be a valid item resource location!
"default_xp": 0,
// Default xp when the player join world for first time. This isn't the same of level!
"max_level": 10,
// Max level for that skill
"unlocked_max_level": 20
// This a special level that can only be unlocked by code.
// Useful to restrict player to "max_level" until they complete some challenge.
}
Alright now you have your creativity skill!

Koko server crashes on startup – what to do?
Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Koko officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Koko – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Koko consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
