Question

我正在Unity3D中开发太阳系动画。行星围绕太阳旋转。但是我有一个模拟像Moon这样的卫星的问题。月亮应该正常环绕世界，月亮应该围绕世界旋转。由于世界在太阳周围转动，我在计算月球的真实旋转方面遇到了麻烦。我不想使用rotateAround（），因为它已被弃用。我需要使用Rotate（）完成此操作。

这是我的planetScript

public class planetScript : MonoBehaviour {

    public GameObject target;//target is Sun for World, World for Moon etc

    public float rotateRatioCenter;//1 degree for World
    private float rotateSpeedTarget;

    public float rotateRatioAround;//365 for World
    private float rotateSpeedAround;

    public float counter = 0;
    void Start () {
    }

    // Update is called once per frame
    void Update () {

     rotateSpeedTarget = rotateRatioCenter * gameMasterScript.rotateAroundCenterRatio;//  rotateRatioCenter * 1 , 
     rotateSpeedAround = rotateSpeedTarget * rotateRatioAround;
     float yRotate = transform.eulerAngles.y;

     transform.Rotate(Vector3.up, rotateSpeedAround);

     rotateAroundTarget();
    }

    void rotateAroundTarget()//this is the method should be optimized
    {
        Quaternion quaRot = Quaternion.Euler(0, rotateSpeedTarget, 0);
        transform.position = quaRot * (transform.position - target.transform.position) + target.transform.position;
    }
}

月亮正在路上!! 我在行星脚本中使用卫星对象解决了它，而不是为它们分配行星脚本。 PlanetScript现在有一个卫星GameObject。

检查行星是否有卫星。
如果是这样的话，可以像在太阳周围旋转行星一样旋转卫星。

旋转行星后，卫星围绕太阳旋转现在可以围绕行星旋转卫星（例如，围绕太阳旋转1度的世界围绕太阳旋转卫星1度并围绕太阳旋转月亮x度行星）当世界围绕太阳旋转1度时，月球在世界范围内旋转大约12度（1月亮年= 30天差不多）。新脚本

public class planetScript：MonoBehaviour {

public GameObject target;//target is Sun for World, World for Moon etc
public GameObject satellite;

public float rotateRatioCenter;//1 degree for World
public float rotateRatioAround;//365 for World
private float rotateSpeedTarget;
private float rotateSpeedAround;

public float satelliterotateRatioCenter;//12x for Moon
public float satelliteRotateRatioAround;//1 for Moon
private float satelliteRotateSpeedTarget;
private float satelliteRotateSpeedAround;

public float counter = 0;
void Start () {
}

// Update is called once per frame
void Update () {

 rotateSpeedTarget = rotateRatioCenter * gameMasterScript.rotateAroundCenterRatio;//  rotateRatioCenter * 1 , 
 rotateSpeedAround = rotateSpeedTarget * rotateRatioAround;

 satelliteRotateSpeedTarget = satelliterotateRatioCenter * gameMasterScript.rotateAroundCenterRatio;
 satelliteRotateSpeedAround = satelliteRotateSpeedTarget * satelliteRotateRatioAround;

 transform.Rotate(Vector3.up, rotateSpeedAround);



 rotateAroundTarget();
}

void rotateAroundTarget()//this is the method should be optimized
{
    Quaternion quaRot = Quaternion.Euler(0, rotateSpeedTarget, 0);
    transform.position = quaRot * (transform.position - target.transform.position) + target.transform.position;

    if (satellite != null)
    {
        satellite.transform.Rotate(Vector3.up, satelliteRotateSpeedAround);
        satellite.transform.position = quaRot * (satellite.transform.position - target.transform.position) + target.transform.position;

        Quaternion quaRotSat = Quaternion.Euler(0, satelliteRotateSpeedTarget, 0);
        satellite.transform.position = quaRotSat * (satellite.transform.position - transform.position) + transform.position;
    }
}

}

由于每架飞机都没有卫星，因此应更改脚本。

围绕旋转物体旋转物体？
