19 Inventory & Loot

In this tutorial we’ll add items and a currency to the game.

Items can do the same things abilites can, but are (usually) consumables that are removed from the inventory upon use. You can also create non-consumable and even non-useable items, e.g. for quests or crafting recipes, or to progress in your game. Learn more about items in this documentation.

Currency can be used to purchase things in shops, to pay for status upgrades (e.g. via research trees) and more. Learn more about currencies in this documentation.

We’ll set up multiple inventory-related things:

  • inventory settings
  • item types
  • currency
  • 5 items (potions)
  • loot
  • start inventory

Let’s get to it!

Inventory Settings #

Navigate to Inventory > Inventory Settings, we’ll check how the inventory system is set up. You can learn more about the inventory system in this documentation.

We’ll use the group inventory (i.e. all combatants in a group share the inventory), auto stack items and equipment and not use any kind of quantity or stack size limit – so, we’ll stick with the default setup of a new project.

  • Inventory Type
    Select Group.
  • Item Stack Type
    Select Auto Stack.
    Items will automatically stack when added to the inventory.
  • Equipment Stack Type
    Select Auto Stack.
    Equipment will automatically stack when added to the inventory.
  • Limit Quantity
    Disable this setting.
  • Limit Stack
    Disable this setting.

There’s a lot more settings available to control inventory related things, but we don’t really need to change anything for now. We’ll later revisit this, e.g. to set up item collection dialogues.

Item Types #

Next, we’ll set up item types.

Navigate to Inventory > Item Types, we’ll change the Default type and add two new item types.

0: Potions #

All potions will be part of this item type.
