In this tutorial we’ll set up the player’s roll ability.
The roll ability will simply roll on the floor, e.g. to use it as an evasive maneuver. Rolling will cost stamina and also grants damage immunity for a short time.
We’ll set up:
- the roll schematic
- the damage immunity (status effect)
- the roll ability
- update Ellen (adding the ability)
- update the control map
Let’s roll!
Roll Schematic #
First, we’ll set up the schematic animating the roll. It’s pretty simple, we’ll play a sound and an animation.
Navigate to Schematics and start working on a new schematic.
Calculate Action #
Add Node > Battle > Action Outcome > Calculate Action
This node will calculate the outcome of the action – i.e. it’ll consume the use costs (stamina) and add the damage immunity effect.
No further settings needed in this node.
Play Sound #
Add Node > Audio > Audio > Play Sound
We’ll play a selected audio clip.
- Object (Play On)
Select Machine Object. - Audio Clip Asset
Select footstep06. - Play One Shot
Enable this setting. - Set Pitch
Enable this setting. - Random Pitch
Enable this setting. - Pitch
Set to 0.4. - Pitch 2
Set to 0.6.
Combatant Animation #
Add Node > Animation > Combatant > Combatant Animation
We’ll play the Roll animation type and wait for most of it.
- Object
Select Machine Object. - Animation Type
Select Roll. - Wait
Enable this setting. - Normalized Time (Wait)
Set to 0.7.
And that’s it for the schematic. Click on Save Schematic to save it, e.g. as EllenRoll.
Damage Immunity Status Effect #
Status effects can block changes to status values – we’ll block negative changes to HP for a second.
Navigate to Status > Status Effects and add a new status effect.
- Name
Set to Damage Immunity.

That’s it for the effect’s setup.
Roll Ability #
The roll ability will cost 20 stamina, is just used on the user itself and doesn’t have any target changes – instead, it’ll use a user change to add the damage immunity effect. It’s also not cancelable (like the attacks).
Navigate to Status > Abilities and add a new ability.

Testing #
Hit play and roll around!
Our player controls aren’t blocked, so we can even change the direction of the roll (in case you don’t want that, enable the Block Player Control setting in the schematic’s Settings node).
Since our player is moved using root motion in the animator, the movement is handled by the rolling animation – our player control input just changes the direction, but since the roll animation is playing, the animator doesn’t play the movement animations.
You can also change the direction of the attacks, since the player control isn’t blocked there as well.
If you time it right, you can use the roll to avoid getting damaged.
Next, we’ll add a new enemy, the spitter!
