## 1. Update と FixedUpdate 関数

[Video](http://www.youtube.com/watch?v=u42aWzAIAqg)

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

public class UpdateAndFixedUpdate : MonoBehaviour
{
    void FixedUpdate ()
    {
        Debug.Log("FixedUpdate time :" + Time.deltaTime);
    }
    
    
    void Update ()
    {
        Debug.Log("Update time :" + Time.deltaTime);
    }
}
```
