Stackable Item Definition

Stackable items track quantity inside one inventory entry. Use them for ammo boxes, scrap, food portions, crafting materials, or any other item type that should combine into stacks.

Placement

Register stackable items in:

garrysmod/gamemodes/[schema folder]/schema/definitions/sh_items.lua

Use lia.item.registerItem in that shared file to define the item directly from code.

Reference

Field	Type	Purpose
name	string	Display name shown in the inventory.
model	string	World and inventory model used by the item.
width	number	Inventory width in slots.
height	number	Inventory height in slots.
isStackable	boolean	Marks the item as using stack quantity logic.
maxQuantity	number	Maximum number of units allowed in one stack.
canSplit	boolean	Controls whether players are allowed to split the stack.

Example

lia.item.registerItem("ammo_box", "base_stackable", {
    name = "Ammo Box",
    model = "models/props_junk/cardboard_box001a.mdl",
    width = 1,
    height = 1,
    isStackable = true,
    maxQuantity = 50,
    canSplit = true
})
