標題: 學習 processing 語言很不錯
本帖最後由 return 於 2015-11-8 00:36 編輯

最近接觸了一種視覺化的基於JAVA的語言叫 processing，覺得不算難學，很快可以上手，做一些小遊戲。

最近做了很簡單的打磚塊和幾A幾B這種猜數字的小遊戲，頗有點成就感。只是程式本身就像一個充滿了補丁的衣服一樣，缺什麼補什麼，錯哪裡再改哪裡，所以十分凌亂，但執行起來還「堪用」吧。

打磚塊的遊戲 http://q.to/pong
只有一排磚，打完了會再出現。一開始請用滑鼠點一下圖中間，然後用滑鼠或者左右鍵來移動下方的板子。球往上時比較慢，下墜時會加快。可能會有些bug，請多指教。

有興趣學程式語言的版友也不妨去玩看看。
