In this tutorial repository you will learn how you can implement Enemy AI with a Finite State Machine. This is a full implementation using Unity Hierarchical State Machine (Unity HFSM which is marked as a package manager dependency already), a code-driven state machine framework for Unity.

Most of the dependencies are already marked with the Package Manager. However Unity Particle Pack and the Quirky Llama (<-- affiliate link) are not included. Not clear on the redistribution rights of Unity Particle Pack, but definitely can't give away the paid asset.

This is intended to be used as reference with the associated video tutorial, but you can of course use it for whatever you want.

• Import Unity Particle Pack
• Replace Llama with your favorite 3d model or import the Quirky Llama
  • Ensure your Animator for your model has the state names as we have defined in ChaseState, IdleState, SpitState, BounceState, AttackState, and RollState. The names can be changed to whatever animations you have.
• Maybe run Built-In -> URP Render Pipeline Material Converter (Window > Rendering > Render Pipeline Converter)
• Click play!

• For the Llama Model, you'll need the Quirky Llama (<-- affiliate link) which is a paid asset. You can choose to replace this with any other 3d model and animations you wish. If you own this Llama, you can simply import it and it will hook it self up. You may need to change to the ShaderGraphs/ variant of the included shader since this is a URP project.
