項目後期Lua接入筆記07--預製屬性轉lua代碼

有些功能可能已經完成一部分了，或者lua中自己寫find屬性很麻煩，字符串很長，這裏我們需要自己寫一個工具來獲取這些數據。
需要的功能就是預製體已經有c#並將屬性拖入代碼文件了，我們將對應的路徑轉成lua代碼

            }
        }

        string str = sb.ToString();
        str = str.Replace(":GetComponent('UnityEngine.Transform')", "");
        str = str.Replace(":GetComponent('UnityEngine.GameObject')", ".gameObject");
        str = str.Replace("True", "true").Replace("False", "false");
        str = str.Replace(trans.name + "/", "");
        EditorTools.CopyText(str);
    }
}

對應的copyText的代碼

    /// <summary>
    /// 將字符串複製到剪切板
    /// </summary>
    /// <param name="text"></param>
    public static void CopyText(string text)
    {
        if (string.IsNullOrEmpty(text)) return;

        TextEditor te = new TextEditor();
        te.text = text;
        te.OnFocus();
        te.Copy();
    }

使用時選擇掛了腳本的gameobject，右鍵選擇GameTools/GetPrefabVar，然後在lua代碼直接粘貼就行了。
