📘 1. Gmod Items Dealers Configurator Addon Description

Gmod Items Dealers allows you to place dealers on your Gmod server who can buy and resell anything you have predefined in their shop from the entity management interface.

This means that with this one script, you can create a mineral dealer for mining systems, a weapon dealer, an ammunition dealer, a healing item dealer, etc. The limit is your imagination.

He takes into account the notion of limited stock thanks to his merchant inventory and economy thanks to his own wallet.

His wallet will allow him to buy back your materials, weapons or ammunition. The items that the merchant buys back from you will constitute his own stock which will allow him to resell them. You will determine the percentage of the resale price of the materials in relation to the purchase price.
The NPC can only sell what he has in his inventory. This means that he will also have the possibility of being out of stock.

You will also have the option of ignoring the wallet limit and the stock concept to allow the NPC to sell unlimited. It's up to you as it's easily configurable, this is to be adapted to your needs.
