He is showing you a link that describes what you are after.

To create a State machine you will want to use an enum

public enum States {Idle, Walk, Run, Crouch, Attack};

then from there you create an instance of this.

public States currentState;

from there you can now go ahead and create methods for each of these states.

public void Idle()
{
   Debug.Log("We are Idle");
}

What i do is then have a method that allows me to switch or set states

public void SetState(States newState)
{
   currentState = newState;
}

It’s then upto you how you want to enforce the checks on how to determine what state you are in.

For instance

public void Update()
{ 
   if(Input.GetKey(KeyCode.W))
   { 
      SetState(States.Walk);
   }
}

I usually have a method that gets checked all the time

public void CheckStates()
{
    switch(currentState)
         case States.Walk:
         {
              Walk();
         }break;

}

And have this in update although you will want to do more checks etc to filter out unnecessary checks and calls.

Hope this helps you out.
