FPS相机具有y轴限制到一定角度

我正在开始一个新游戏，现在我的玩家可以查看360 *但是我想限制玩家在天空中向下看的距离（直线向上和向下）。 这是我的代码

Vector2 mouseLook; Vector2 smoothV; public float sensitivity = 5.0f; public float smoothing = 2.0f; GameObject player; void Start () { player = this.transform.parent.gameObject; } // Update is called once per frame void Update () { var md = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y")); md = Vector2.Scale(md, new Vector2(sensitivity * smoothing, sensitivity * smoothing)); smoothV.x = Mathf.Lerp(smoothV.x, md.x, 1f / smoothing); smoothV.y = Mathf.Lerp(smoothV.y, md.y, 1f / smoothing); mouseLook += smoothV; transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right); player.transform.localRotation = Quaternion.AngleAxis(mouseLook.x, player.transform.up); } 

}

你必须使用Mathf.Clamp来做到这一点。 以下是我用来向上/向下和向左/向右旋转相机的内容。 您可以将yMaxLimit和yMinLimit变量修改为要将其限制为的角度。 沿x方向移动时应该没有限制。

 public float xMoveThreshold = 1000.0f; public float yMoveThreshold = 1000.0f; public float yMaxLimit = 45.0f; public float yMinLimit = -45.0f; float yRotCounter = 0.0f; float xRotCounter = 0.0f; Transform player; void Start() { player = Camera.main.transform; } // Update is called once per frame void Update() { xRotCounter += Input.GetAxis("Mouse X") * xMoveThreshold * Time.deltaTime; yRotCounter += Input.GetAxis("Mouse Y") * yMoveThreshold * Time.deltaTime; yRotCounter = Mathf.Clamp(yRotCounter, yMinLimit, yMaxLimit); //xRotCounter = xRotCounter % 360;//Optional player.localEulerAngles = new Vector3(-yRotCounter, xRotCounter, 0); }
