我編寫了一些代碼，允許用戶通過在流媒體資源中加載輸入圖像，然後使用這些圖像創建對象，在編輯器模式下實例化對象。統一預製代理怪異？
這很好，問題是當我嘗試用這些對象之一創建一個預製件時。出於某種原因，圖像沒有保存在預製件中，所以當我加載預製件時，我得到的是白色圖像，而不是原始遊戲對象中的圖像。
更新：事實證明，我的背景屏幕實際上正常工作，但沒有其他的gameobjects。所以我不確定什麼是錯的，爲什麼它只爲一些物體而不是另一個物體工作。
這裏是我的代碼：

感謝您的回覆，所以我嘗試了undo.record（gameobject，「添加了更改），並將它放在place對象函數中，但它仍然不起作用。 ？腳本文件有點模糊 –
@SamBasiony添加了撤消操作並對對象進行更改後，Unity是否顯示場景中有變化？（它會在層次結構窗口中用星號標記場景名稱（* ）之後，試着在每次改變場景後對場景中的對象進行髒標記 – vmchar
我試圖將場景標記爲髒，並且它不工作，因爲它表示它在運行時無法工作。我剛剛找到了一個解決方案。 –
