Creating Items

When creating content, you might want to add your own cool item to the game. This page will walk you through creating your own item and discuss how you can use it in the game.

Creating Item Graphics

Item sprites should be PNG images that are 24 x 24 pixels in size. Here is an example of some item sprites:

After creating your item sprite, put your graphic under mods/tuxemon/gfx/items.

Using your item in Tuxemon

You can add your item to the player's inventory by creating an *action event* with an action type of "add_item" using the Tiled map editor. For more information on adding event actions and conditions to a map, check out the Map Editor Events.

Item Design

Items in Tuxemon can be created by adding a JSON file to the mods/tuxemon/db/item directory. With each new item, the following data must be specified:

Name	Description
conditions	Conditions are the prerequisites on which an item can be used or not. By using the example below: "is current_hp <,1.0", and "is current_hp >,0" means that the item can be used on a monster with more than 0 HP (not fainted) and less that the total (not healthy).
effects	Effects can change some characteristics of the monster on which the item is used. By using the example below: "heal 20" means to heal 20 HP.
slug	The slug identifier of the item. It defines the name of the item and there is a translation in the PO file (msgid "potion" - msgstr "Potion") as well as the description (msgid "potion_description" - msgstr "Heals a monster by 20 HP.").
sort	It can be "food", "potion", "utility" or "quest".
sprite	The sprite / image of the item.
category	It can be "none", "badge", "booster", "elements", "fossil", "morph", "revive", "potion", "technique", "phone", "fish", "destroy", "capture" or "stats".
type	It can be KeyItem or Consumable, or neither. KeyItems should generally not be able to be sold. If used, then Consumable is going to remove 1 quantity.
usable_in	Possibilities are: "MainCombatMenuState" (during battle), "WorldState" (in the world) or "" (never)
use_failure	Corresponding msgid (translation PO file) will appear if the item fails.
use_item	Corresponding msgid (translation PO file) will appear when the item is used.
use_success	Corresponding msgid (translation PO file) will appear if the item is used successfully (depending on effects).

Here is an example of what an item file might look like:

`mods/tuxemon/db/item/potion.json`

 "conditions": [
   "is current_hp <,1.0",
   "is current_hp >,0"
