鼠标右键控制相机围绕物体旋转/滚轮控制远近
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveModel : MonoBehaviour
{
public Camera cam;//相机
public float spee = 10;//速度
float x = 0, y = 0;

}
void move()
{
x= Input.GetAxis("Mouse X") * spee;
y += Input.GetAxis("Mouse Y") * spee;//定义在x,y轴上移动
cam.transform.RotateAround(transform.position, Vector3.up, x);
cam.transform.localEulerAngles = new Vector3(-y, cam.transform.localEulerAngles.y, 0);//相机移动（旋转角度）
}
// Update is called once per frame
void Update()

代码给物体，把相机拖到cam

发现新问题：发现在模型一个方向旋转180度后另一个方向的控制会出问题，本来鼠标向左模型向左旋转，向上或向下旋转180度后，鼠标向左模型向右
改善方法
代码如下：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveModel : MonoBehaviour
{
public Camera cam;
public float spee = 5;
public float speedrotate = 50;
float x = 0, y = 0;
public float m_camFieldOfViewMin;
public float m_camFieldOfViewMax;
private void Awake()
{
m_camFieldOfViewMin = 15;
m_camFieldOfViewMax = 100;
}
void Start()
{
}
static float ClampAngle(float angle, float minAngle, float maxAngle)
{
if (angle < -360)
angle += 360;
if (angle > 360)
angle -= 360;
return Mathf.Clamp(angle, minAngle, maxAngle);
}
void move()
{
float fMouseX = Input.GetAxis("Mouse X");
float fMouseY = Input.GetAxis("Mouse Y");
transform.Rotate(Vector3.up, -fMouseX * spee, Space.World);
transform.Rotate(Vector3.right, fMouseY * spee, Space.World);
}
// Update is called once per frame
void Update()
{
if (Input.GetMouseButton(1))
{
move();
}
if (Input.GetAxis("Mouse ScrollWheel") < 0)
{
if (cam.fieldOfView < m_camFieldOfViewMax)
{
cam.fieldOfView += 2;
}
if (cam.orthographicSize <= 10)
{
cam.orthographicSize += 1f;
}
}
if (Input.GetAxis("Mouse ScrollWheel") > 0)
{
if (cam.fieldOfView > m_camFieldOfViewMin)
{
cam.fieldOfView -= 2;
}
if (cam.orthographicSize >= 1)
{
cam.orthographicSize -= 1f;
}
}
}
}
同样代码给物体，把相机拖到cam
