Silverlight

作者的話：

開誠布公的說，我對于JavaFX沒有什么好印象，我想這可能是以下原因造成的：

1、沒有任何UI編輯工具，我總要與腳本打交道。如果只能用編碼方式進行開發(fā)，那可就一點也不好玩了。

2、應(yīng)用程序老是需要花費很長時間才能加載成功，我不知道為什么會這樣，總之每次在IE中啟動程序，都要過一小段才能顯示出內(nèi)容。

3、以JavaFX運行程序，不但需要.jar文件，還要去配置.jnlp。

4、我不知道哪些屬性可以與特定對象相關(guān)聯(lián)。

5、有些時候，調(diào)試器無法獲得正確的錯誤位置。

6、JavaFx是一種全新的腳本，學(xué)習(xí)它需要很長時間。

7、當(dāng)滾動頁面時，JavaFX中可能會出現(xiàn)殘像。

實際上，除此之外我還有一些不好的體驗，就不一一列舉了。

可能有人會說，JavaFX是一個相對較新的技術(shù)，這些都是很平常的問題，你需要耐心等待。我同意這一點，因此我將等待JavaFX的后續(xù)發(fā)展，然后再花時間學(xué)習(xí)它。

我還記得，Silverlight在它的第一版中也沒什么吸引力。那么，JavaFX下面會怎么樣呢？

另外，筆者自己再補充個LGame-Simple的實現(xiàn)：
