first up, im in neoforge 1.21.4, idk if it works in other versions and im not testing it

2) paste this code and change my mod name into yours ex. package net.mcreator.forgottenrelics.client; ------> package net.mcreator.yourmod.client; and so on, change everywhere you see ForgottenItems or similar into your mod name
