unity实现自转及公转

创建俩个sphere，然后创建一个脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class zhuan : MonoBehaviour
{
    /// 

    /// 这是子物体公转的对象
    /// 
    public Transform m_sphere;
    /// 

    /// 用于自转的子物体
    /// 
    public Transform m_sphereA;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        //自转
        m_sphereA.Rotate(Vector3.up, Space.Self);
        //公转
        m_sphereA.RotateAround(m_sphere.position, m_sphere.up, Time.deltaTime * 50);//这是用来控制旋转的速度
    }
}

创建好脚本之后在创建一个空物体，将代码拖进去，然后将刚刚创建的俩个用于旋转的物体拖入

然后运行即可
