Unity3d 在Unity 3D版本2019中围绕太阳旋转地球

我已经在unity 3D中创建了一个场景。它有三个球体，一个是太阳，第二个是地球，第三个是月亮。我已使月亮成为地球的孩子。我的地球垂直地绕着太阳转，月亮绕着地球转。我想要在水平轴上旋转

革命的代码如下：

using UnityEngine;
using System.Collections;

public class revolve : MonoBehaviour {

public Transform target;    // the object to rotate around

public int speed;   // the speed of rotation

void Start()
 {
if (target == null) 
{
target = this.gameObject.transform;
Debug.Log ("RotateAround target not specified. Defaulting to parent GameObject");
}}

// Update is called once per frame
void Update () 
{
// RotateAround takes three arguments, first is the Vector to rotate around
// second is a vector that axis to rotate around
// third is the degrees to rotate, in this case the speed per second
transform.RotateAround(target.transform.position,target.transform.forward,speed * Time.deltaTime);
}}

建议在水平轴上旋转所做的更改。

更改最后一行

 transform.RotateAround(target.transform.position,target.transform.forward,speed * Time.deltaTime);

到

 transform.RotateAround(target.transform.position,target.transform.right,speed * Time.deltaTime);
