UnityでFPSゲームを作る①FPS視点操作

前回の記事で作ったFPS視点のスクリプトの問題点を改良します。

 

前回のスクリプトの問題点

  • 視点が一回転できてしまう。

ので縦方向の視点操作を制限しましょう。

以下が前回のPlayerController.csを改良したものです。

    private Transform CameraTransform;
    private float ii;
    // Use this for initialization
    void Start () {
 
        PlayerTransform = transform.parent;
        CameraTransform = GetComponent<Transform>();
 
    }
// Update is called once per frame
void Update () {
        float X_Rotation = Input.GetAxis("Mouse X");
        float Y_Rotation = Input.GetAxis("Mouse Y");
        PlayerTransform.transform.Rotate(0, X_Rotation, 0);
        
        ii = Camera.transform.localEulerAngles.x;
        if (ii > 334 && ii < 360 || ii > 0 && 79 > ii)
        {
            CameraTransform.transform.Rotate(-Y_Rotation, 0, 0);
            float kk = Y_Rotation;
        }
        else
        {
          
            if (ii > 300)
            {
 
                if (Input.GetAxis("Mouse Y") < 0)
                {
 
                    CameraTransform.transform.Rotate(-Y_Rotation, 0, 0);
 
                }
            }
            else
            {
                if (Input.GetAxis("Mouse Y") > 0)
                {
 
                    CameraTransform.transform.Rotate(-Y_Rotation, 0, 0);
 
                }
 
            }
        }
 
        float angleDir = PlayerTransform.transform.eulerAngles.y * (Mathf.PI / 180.0f);
        Vector3 dir1 = new Vector3(Mathf.Sin(angleDir), 0, Mathf.Cos(angleDir));
        Vector3 dir2 = new Vector3(-Mathf.Cos(angleDir), 0, Mathf.Sin(angleDir));
        
        
        if (Input.GetKey(KeyCode.W))
        {
            PlayerTransform.transform.position += dir1 * speed * Time.deltaTime;
        }
        if (Input.GetKey(KeyCode.A))
        {
            PlayerTransform.transform.position += dir2 * speed * Time.deltaTime;
        }
        if (Input.GetKey(KeyCode.D))
        {
            PlayerTransform.transform.position += -dir2 * speed * Time.deltaTime;
        }
        if (Input.GetKey(KeyCode.S))
        {
            PlayerTransform.transform.position += -dir1 * speed * Time.deltaTime;
        }
 
    }
}

これでいい感じに角度が制限させると思います。
