24.总结

7.子对象嵌套

7.1 知识点

创建获取路径函数解决控件有父对象的情况

/// <summary>
/// 获取对象的父对象关系，拼接路径用于获取控件
/// </summary>
/// <param name="obj"></param>
/// <returns></returns>
private string GetPath(Transform obj, Transform panelTrans)
{
    string path = obj.name;
    while (obj.parent != panelTrans)
    {
        path = obj.parent.name + "/" + path;
        obj = obj.parent;
    }

    return path;
}

在找控件拼接信息中调用

info.findStr +=
$"{controls[i].gameObject.name} = this.transform.Find(\"{GetPath(controls[i].transform, obj.transform)}\").GetComponent<{type.Name}>();\n\t\t";
