CodeEffect

For Users

This mod doesn't do anything on its own. This library allows mods to call code in data-driven enchantments.

For Devs

Registering your code:

CodeEffect.register(HOOK_ID, (world, level, context, user, pos) -> {
    // Code Here
});

or

CodeEffect.register(HOOK_ID, this::stuff);
// ...
public void stuff(ServerWorld world, int level, EnchantmentEffectContext context, Entity user, Vec3d pos) {
    // Code Here
}

Using it:

"effect": {
     "type": "code_effect:run_code",
     "hook": "HOOK_ID"
}

Full Enchantment example:
Sharpness but modified to run the code every tick
