Installation

Requirements:

• Dunko vRP

How to Install:

• Download the resource,place it your /resource folder.
• Start the resource in your server.cfg.
• Replace vrp/modules/inventory.lua with the following one:

inventory.lua

    local lang = vRP.lang
    local cfg = module("cfg/inventory")

    -- this module define the player inventory (lost after respawn, as wallet)

    -- idname: unique item name
    -- name: display name or genfunction
    -- description: item description (html) or genfunction
    -- choices: menudata choices (see gui api) only as genfunction or nil
    -- weight: weight or genfunction
    --
    -- genfunction are functions returning a correct value as: function(args) return value end
    -- where args is a list of {base_idname,arg,arg,arg,...}
