Authors and contributors to this experimental extension: infokubarcade, WickedSidereal.

Warning

This is an extension made by a community member and it only got through a light review by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of fully reviewed extensions.

Store content in any kind of slots.

Usages

  • Add, count and remove items from slots
  • Check how many slots are filled or empty
  • Set a maximum or unlimited amount of items for every slot
  • Add and remove properties of a slot (weapon category, item class, object weight...)
  • Move a slot content to an other position
  • Sum a property (good for weight system)
  • Sort items using a property value (ascending alphabetical only)
  • Flood system : add items automatically and when they reach the maximum of the slot, they go in the next empty slot
  • Export/Import spaces as JSON

Systems

  • 3 systems available (Basic, Named slots and Grid)

Basic

Use numbers as slot identifiers to retrieve your informations

Named slots

Use texts as slot identifiers. Very useful when you want to put an item on a specific part of your character.

Grid

Use a 2D grid position to retrieve your informations. It uses the basic slot system in a more handy way.

Tip
