Unity Utilityai

unity-utilityai

A very basic use of Utility AI for Unity.

The concept is each AI has a brain component which you load with thoughts which are scriptable objects. Each thought is checked and returns a number from 0 - 100.

The lowest number returned is the most urgent and gets executed.

Usage

Add the AI brain to your NPC’s and then create your own thoughts by extending the base thought. When a thought is weighed or executed it gets sent the gameobject of its owner, you can use this to access the information to make the decision.

When you create a new thought you need to also make a scriptable object based off it. This is what you add to your AI’s brain. Each though has a curve which allows you adjust its urgency.
