# イベント

イベントを活用してロジックを疎結合に保つ、動的なブロードキャスト型メッセージシステムを構築します。

イベントを使用して動的な「ブロードキャスト」システムを作成する方法を学びます。

**EventManager クラスのコード**

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

public class EventManager : MonoBehaviour 
{
    public delegate void ClickAction();
    public static event ClickAction OnClicked;


    void OnGUI()
    {
        if(GUI.Button(new Rect(Screen.width / 2 - 50, 5, 100, 30), "Click"))
        {
            if(OnClicked != null)
                OnClicked();
        }
    }
}
```

**TeleportScript クラスのコード**

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

public class TeleportScript : MonoBehaviour 
{
    void OnEnable()
    {
        EventManager.OnClicked += Teleport;
    }


    void OnDisable()
    {
        EventManager.OnClicked -= Teleport;
    }


    void Teleport()
    {
        Vector3 pos = transform.position;
        pos.y = Random.Range(1.0f, 3.0f);
        transform.position = pos;
    }
}
```

**TurnColorScript クラスのコード**

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

public class TurnColorScript : MonoBehaviour 
{
    void OnEnable()
    {
        EventManager.OnClicked += TurnColor;
    }


    void OnDisable()
    {
        EventManager.OnClicked -= TurnColor;
    }


    void TurnColor()
    {
        Color col = new Color(Random.value, Random.value, Random.value);
        renderer.material.color = col;
    }
}
```
