Setting up the player’s damage, death and the fall remover.
In this tutorial we’ll create 2 schematics – one handling the player taking damage from enemies and death, the other removing everything that falls into the river (with a splash) and restarting the game if the player died.
Player Damage: Schematic
First, we’ll create the schematic that handles the player taking damage from touching enemies and dying when the health is gone. The schematic will be added to the player using a collision machine.
Open the Makinom editor, navigate to Schematics and create a new schematic. Change the following settings.
Settings
We’ll add an audio clip resource that will be played when the player takes damage.
Audio Clips

Select Player-ouch1 to Player-ouch4.
The audio clips can be found at Assets/Tutorial Resources/Audio/Player/Ouch/.

That’s it for the schematic – click on Save Schematic and save it as PlayerDamage in Assets/Schematics/.
Player Damage: Collision Machine
Now, we’ll add the schematic to the player using a collision machine. We’ll limit the machine to only start when colliding with game objects tagged Enemy.
Select the hero game object in the scene hierarchy, add a collission machine component (e.g. using the component menu: Makinom > Machines > Collision Machine) and change the following settings.
Start Settings
- Collision Enter
Enable this setting. - Collision Stay
Enable this setting.
When the player keeps colliding with the enemy, we want to continue to take damage. - Start By Other
Enable this setting.
Click on Add Check to add a game object check for the objects we collide with.
- Check Type
Select Tag. - Name
Set to Enemy. - Check Type
Select Is Equal. - Is Valid
Enable this setting.
Machine Execution Settings
- Asset Type
Select Schematic. - Schematic Asset
Select PlayerDamage. - Execution Type
Select Single. - Update Type
Select Update. - End Delay Time (s)
Set to 0.5.
This will let the player only take damage every 0.5 seconds.
That’s it for the player’s game object – apply the changes to the prefab by clicking on Apply (top of the inspector).
Fall Remover: Schematic
Next, we’ll set up the schematic that will remove everything that falls into the river. When something falls into the river, we’ll display a splash effect and – if the game object is the player – restart the game. The player falling into the river can happen in 2 ways – the player running into it, or the player dying and falling down – both result in game over.
Open the Makinom editor, navigate to Schematics and create a new schematic. Change the following settings.
Settings
We’ll display a splash game object (an animated sprite) at the position something fell into the river, i.e. we need a prefab resource.
