unity3D对象的显示和隐藏

SetActive/active/SetActiveRecursively 后两者比较旧,现在通常用第一个SetActive

必须先new一个gameobject对象用于实例化,然后再设置其active状态.不然会出错哦

 GameObject gb;
void Start()
    {
        gb = GameObject.FindGameObjectWithTag("Playbutton");
    }
  void OnClick() {
 
        if (gb.active == true)
        {
            gb.SetActive(false);
 
        }
        else if (gb.active == false)
        {
            gb.SetActive(true);
        }
