Time for action – storing collected items

To test this out, you're going to modify the existing item collection logic in Hero Born by using a stack to store possible loot that can be collected:

1. Open GameBehavior.cs and add in a new stack variable named lootStack:

// 1
public Stack<string> lootStack = new Stack<string>();

2. Update the Initialize method with the following code to add new items to the stack:

public void Initialize() 
{
    _state = "Manager initialized..";
    _state.FanceyDebug();
    Debug.Log(_state);

    // 2
     lootStack.Push("Sword of Doom");
     lootStack.Push("HP+");
     lootStack.Push("Golden Key");
     lootStack.Push("Winged Boot");
     lootStack.Push("Mythril Bracers");
}

3. Add a new method to the bottom of the script to print out the stack information:

// 3
public void PrintLootReport()
{
    Debug.LogFormat("There are {0} random loot items waiting for
       you!", lootStack...
