In this tutorial we’ll set up a healing potion for the player.
This time we’re setting up an item – it’ll heal 50 HP when used.
We’ll set up:
- potion schematic
- potion item
- update the control map
- add some potions to the player’s start inventory
Let’s get to it!
Potion Schematic #
Using the potion will be pretty simple, we’ll spawn a particle effect prefab, play an animation, wait and calculate the item’s outcome.
Navigate to Schematics and start working on a new schematic.
Settings #
We’ll block the player controls while using the potion, i.e. the movement input doesn’t rotate the combatant’s game object (it wouldn’t move in any case, since we’re using root motion for that).

Enable this setting.
Prefabs #
We also add the particle effect prefab.
Click on Add Prefab Resource.
