public void bt2() { if (Pan2.activeSelf == false) { Pan2.SetActive(true); Imag2.SetActive(true); Pan1.SetActive(false); Imag1.SetActive(false); Pan3.SetActive(false); Imag3.SetActive(false); Pan4.SetActive(false); Imag4.SetActive(false); Pan5.SetActive(false); Imag5.SetActive(false); } else { Pan2.SetActive(false); Imag2.SetActive(false); } } public void bt3() { if (Pan3.activeSelf == false) { Pan3.SetActive(true); Imag3.SetActive(true); Pan1.SetActive(false); Imag1.SetActive(false); Pan2.SetActive(false); Imag2.SetActive(false); Pan4.SetActive(false); Imag4.SetActive(false); Pan5.SetActive(false); Imag5.SetActive(false); } else { Pan3.SetActive(false); Imag3.SetActive(false); } } unity 用更好的方法整理减少这段代码

可以将重复的代码提取出来，写成一个函数，然后在需要使用的地方调用该函数即可，如下所示：

public void ShowPanel(GameObject panel, GameObject image)
{
    panel.SetActive(true);
    image.SetActive(true);

    foreach (Transform child in transform)
    {
        if (child.gameObject != panel && child.gameObject != image)
        {
            child.gameObject.SetActive(false);
        }
    }
}

public void bt2()
{
    if (Pan2.activeSelf == false)
    {
        ShowPanel(Pan2, Imag2);
    }
    else
    {
        Pan2.SetActive(false);
        Imag2.SetActive(false);
    }
}

public void bt3()
{
    if (Pan3.activeSelf == false)
    {
        ShowPanel(Pan3, Imag3);
    }
    else
    {
        Pan3.SetActive(false);
        Imag3.SetActive(false);
    }
}
