To start, you need to have a character with a few animations. In this example, we are using a character with NormalIdle, NormalMove, CombatIdle, and CombatMove animations. These animations will be then grouped in two Sub-State Machines: Combat and Normal.

You can also open the provided example Unity project and go to the Chapter 06 Handling combatRecipe 01 Using sub state machines in animator controller directory. In the Rigs directory you, will find all the necessary animations. In the Controllers directory, you can find the finished controller with two Sub-State Machines. You can find the Humanoid character in the Example.unity scene. If you press the space bar, our character will switch from Normal to Combat Sub-State Machine.
