### For Users
\nThis mod doesn’t do anything on its own. This library allows mods to call code in data-driven enchantments.<\/p>\n
### For Devs

\n“`java
\nCodeEffect.register(HOOK_ID, (world, level, context, user, pos) -> {
\n \/\/ Code Here
\n});
\n“`
\nor
\n“`java
\nCodeEffect.register(HOOK_ID, this::stuff);
\n\/\/ …
\npublic void stuff(ServerWorld world, int level, EnchantmentEffectContext context, Entity user, Vec3d pos) {
\n \/\/ Code Here
\n}
\n“`<\/p>\n
