# カメラを動かす

「Roll-a-Ball」プロジェクトで Camera の位置を設定し、Player のスフィアを固定オフセットで追従するスクリプトを作成します。

この 3 つ目の「玉転がし（Roll-a-Ball）」チュートリアルでは、以下のことを行います：

- カメラ位置の設定
- Camera が Player のスフィアに fixed offset (固定オフセット)で追従するスクリプトを作成します。

## **CameraController スクリプト**

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

public class CameraController : MonoBehaviour
{
    public GameObject player;

    private Vector3 offset;

    // Start is called before the first frame update
    void Start()
    {
        offset = transform.position - player.transform.position;
    }

    // Update is called once per frame
    void LateUpdate()
    {
        transform.position = player.transform.position + offset;
    }
}
```
