 **DelegateScript**

```csharp
using UnityEngine;
using System.Collections;


public class DelegateScript : MonoBehaviour 
{    
    delegate void MyDelegate(int num);
    MyDelegate myDelegate;


    void Start () 
    {
        myDelegate = PrintNum;
        myDelegate(50);

        myDelegate = DoubleNum;
        myDelegate(50);
    }

    void PrintNum(int num)
    {
        print ("Print Num: " + num);
    }

    void DoubleNum(int num)
    {
        print ("Double Num: " + num * 2);
    }
}
```

 **MulticastScript**

```csharp
using UnityEngine;
using System.Collections;

public class MulticastScript : MonoBehaviour 
{
    delegate void MultiDelegate();
    MultiDelegate myMultiDelegate;


    void Start () 
    {
        myMultiDelegate += PowerUp;
        myMultiDelegate += TurnRed;

        if(myMultiDelegate != null)
        {
            myMultiDelegate();
        }
    }

    void PowerUp()
    {
        print ("Orb is powering up!");
    }

    void TurnRed()
    {
        renderer.material.color = Color.red;
    }
}
```
