At the beginning of our AI script, we created some variables that we have yet to properly assign. We will do that in the Start function. We will also add the Update function to run our AI code. Add these functions to the bottom of the class:

void Start()
{
  navAgent = GetComponent<NavMeshAgent>();

  Stats.Add(new KeyValuePair<string, int>("Health", 100));
  Stats.Add(new KeyValuePair<string, int>("Speed", 10));
  Stats.Add(new KeyValuePair<string, int>("Damage", 25));
  Stats.Add(new KeyValuePair<string, int>("Agility", 25));
  Stats.Add(new KeyValuePair<string, int>("Accuracy", 60));
}

void Update ()
{
  RunBehaviors();
}

In the Start function, we first assign the navAgent variable by getting the NavMeshAgent component from the GameObject. Next, we add new KeyValuePair variables to the Stats array. The Stats array is now...
