In this tutorial we’ll set up some simple battle AIs and two enemy combatants.
Before diving into the battle system, we set up two enemies for the player to fight – a wasp and a snake.
The enemies will attack with the base attack (Attack ability) and randomly with a Poison Attack – we’ll set up battle AIs to handle this.
Battle AIs #
AI controlled combatants use battle AIs to select their actions in battle.
A combatant’s default action in battle is using their base attack, when no battle AI is used or no useable action was found, they’ll use their base attack.
We’ll make a very simple setup where the enemies use a random ability that’s available to the combatant (for our wasp and snake it’s the Poison Attack) with a chance of 25, 50 or 75% – otherwise they’ll use their base attack.
Open the ORK editor and navigate to Battles > Battle AIs, we’ll change the Default battle AI and add more battle AIs.
0: Random Ability 25% #
Has a 25% chance to use a random ability (available to the combatant).
In case the chance fails, this battle AI ends, continuing with the next battle AI fo the combatant (or using the base attack if no other battle AI is available).
Battle AI Settings #
- Name
Set to: Random Ability 25%
Chance #
Add Node > Base > Chance
Does chance checks and performs a next node based on it.
The a default chance check is already set up for us (Range 0), so let’s change.
- Minimum Range
Select: Value > Value
Set the value to: 0 - Maximum Range
Select: Value > Value
Set the value to: 25
Ability #
Add Node > Action > Ability
Uses an ability of the combatant – we’ll use a random ability.
The node is connected to the 0 – 25 next slot of the Chance node.
- Use Random Ability
Enable
This’ll use a random ability available to the combatant. - Use Highest Level
Enable
This’ll use the highest available (and usable) level that’s available to the combatant.
We don’t really use abilities with multiple levels in this tutorial series, but it’s still a good practice.
1: Random Ability 50% #
Has a 50% chance to use a random ability (available to the combatant).
Copy the Random Ability 25% battle AI and change the following settings.

Combatant Groups #
Combatant groups can be used by battles, combatant spawners, etc. to create predefined groups.
We’ll set up a group with our two enemies – the group will have 2 of them, but each is randomly selected, so the group could be 2 wasps or 2 snakes, or 1 wasp and 1 snake.
Navigate to Combatants > Combatant Groups, we’ll change the Default group.

Set to: Forest x2
Combatants > Combatant 0 #
This is the first combatant of the group.

- Combatant
Select: Wasp
Copy the random combatant and change the following setting.

Select: Snake
Combatants > Combatant 1 #
We’ll just copy Combatant 0, since we want to use the same setup for the 2nd combatant of the group.
No changes needed to the setup.
Save Changes #
And that’s it for now!
Save the changes using the Save Settings button at the bottom of the editor.
Next, we’ll set up our battle system.
