Away3D和BB Playbook

我在Mobile Actionscript Flash Builder項目中使用Away3D框架，並嘗試調試/在我的bb劇本上運行。當我通過Flash Builder運行/調試時（不是bb特定的playbook），一切都很好。當我嘗試運行我的實際設備/調試我得到以下錯誤：Away3D和BB Playbook

TypeError: Error #1009: Cannot access a property or method of a null object reference.

我知道空對象引用意味着我需要聲明/定義一個變種，但由於在使用Flash Builder完美運行的應用程序我不明白。

任何幫助將不勝感激。我的代碼如下...

好吧，如果你試圖在便攜式設備上進行調試，可能是設備缺少資源來完成編譯？每次你在你的電腦上編譯所有的資源都可用，也許你的設備缺少外部庫。 – joshua 2013-04-07 06:23:48

TypeError：錯誤＃1009：無法訪問空對象引用的屬性或方法。這意味着該對象在它當時爲空來引用它，與聲明一個變量無關 – joshua 2013-04-07 06:26:03

也許你應該在釋放FB時使用「專用包裝」 – 2013-04-07 09:39:52

我不認爲BB劇本的版本AIR的支持Stage3D的，後來我聽見他們使用AIR 3.1。我看過他們計劃使用AIR 3.2或更高版本更新SDK，但不知道是否已經發生。
