摄像机跟随手指旋转

using UnityEngine;

public class CameraRotateFollowFinger : MonoBehaviour {

    bool isRotating = false;

    public GameObject player;

    /// <summary>
    /// 旋转速度
    /// </summary>
    public float speed = 100;

    void Update () {

        RotateView();
    }

    void RotateView()
    {
        if (Input.GetMouseButtonDown(0))
        {
            isRotating = true;

            //unity Input内部维护虚拟的鼠标指针,在有触摸的时候才更新,如果抬起来的话,第一帧的偏移量特别大,把第一帧return掉
            //return 防止手指抬起之后的第一帧偏移量过大,摄像机会回到默认位置
            return;
        }
        if (Input.GetMouseButtonUp(0))
        {
            isRotating = false;
        }

        if(isRotating)
        {
            transform.RotateAround(player. transform.position,Vector3.up,Time.deltaTime* speed * Input.GetAxis("Mouse X"));

        }
     
    }
}
