A small resource containing working Nightvision Goggles, Thermal Goggles, Gas Masks, and my NIK Kits! Gas Masks actually stop damage, Goggles work, and NIK Kits are able to find drugs!
The problem with not removing the item is that you can equip it and then pass the item to others to use. If that’s not a concern, whoever is the dev for your server can make the change easy.
A better way is to save the use of the item to the players data in the database. When your player loads in from a crash or restart, you can reequip the item or give the player the item. Its pretty easy to do. I’m in the middle of doing something similar for this resource .
