Armory Shop System

Armory Shop — General Logic

• Categories: Items are organized into “Weapons, Ammunition, Equipment, Protection, Utility.”

• Rank filter: Each item has a grade. A player only sees/selects items if their job grade meets or exceeds that level.

• Cart flow: Items are added with “Select,” then quantity can be increased/decreased or removed in the cart.

• Quantity system: stack defines how much is added per click (e.g., ammo boxes), and maxPerCart sets the maximum limit per purchase.

• Payment: The total cost is calculated, and the player pays with Card or Cash. If successful, items are added directly to the inventory.

• Item binding: itemName is the actual inventory item name; the system gives that item when purchased.

• Validation: Rank, limits, and funds are checked in the UI and verified again on the server side.

• Configuration: Price, rank, stock/limit, descriptions, and images are all configurable. Adding new items is done by copying a line and editing its fields.

Summary: A simple armory system that works with rank-based visibility, a cart system, and payment options to manage police equipment distribution.
