FollowMouseMove 脚本具体内容如下：

using UnityEngine;

public class FollowMouseMove : MonoBehaviour {

public float moveSpeed = 5.0f;

// Use this for initialization

void Start()

{

}

// Update is called once per frame

void Update()

{

// 获得鼠标当前位置的X和Y

float mouseX = Input.GetAxis("Mouse X") * moveSpeed ;

float mouseY = Input.GetAxis("Mouse Y") * moveSpeed ;

// 鼠标在Y轴上的移动号转为摄像机的上下运动，即是绕着X轴反向旋转

Camera.main.transform.localRotation = Camera.main.transform.localRotation * Quaternion.Euler(-mouseY, 0, 0);

// 鼠标在X轴上的移动转为主角左右的移动，同时带动其子物体摄像机的左右移动

transform.localRotation = transform.localRotation * Quaternion.Euler(0, mouseX, 0);

}

}
