同步雪碧觸摸檢測 - iPhone和cocos2d

我正在寫一個應用程序的iPhone使用cocos2d在哪裏我有4個按鈕的精靈。我想通過使用2個不同的.png文件代表按下/未按下的狀態來實現按鈕功能。我認爲這會比使用動畫更好。除了檢測何時按下和釋放按鈕，我還需要檢測何時發生雙按鍵組合按鍵（如和絃）。我甚至可能把這個轉發到3和4按鈕組合。我想要實現的另一個功能是檢測是否從按鈕內發出輕彈，並用另一個動作序列作出響應。同步雪碧觸摸檢測 - iPhone和cocos2d

什麼是最佳的方法呢？我會使用四個按鈕的邊界矩形或精靈（它們是否在方形陣列中）併吞下觸摸？那麼我會使用較小的精靈rects來確定觸摸發生在哪一個？或者我會讓單個sprite rects進行檢測，然後讓他們檢查其他按鈕是否也被按下，然後同時釋放？我會使用Bool狀態變量用於這兩種方式嗎？

我已經使用CCMenu和CCMenuitem，通過爲每個按鈕精靈製作一個Menu/Menu-item，然而，我無法弄清楚如何檢測一個菜單中的菜單項是否被按下並釋放，同時按下並釋放了不同菜單中的菜單項。我使用了單獨的菜單，因爲如果我使用多個菜單項相同的菜單，則一次只能按一個菜單項。我說它工作得很好，這意味着它可以在單臺和多臺印刷機上工作，但它會將倍數視爲兩次連續印刷，而不是同時印刷。 IE瀏覽器：單次按下導致運行一個單一的動作序列（按照預期），同時按下按鍵組合導致爲每個按鈕運行單獨的按鈕動作序列，就好像我分別按下它們一樣（我希望它運行一個特定的動作序列到那個按鈕組合）。這就是爲什麼我決定嘗試實現我自己的按鈕系統而不是使用CCMenu系統可能更好。我是否正在擺脫CCMenu？

對不起，很長的描述，但它確實說具體。 B）

任何有關其他人如何實現或將實現這一點的深刻見解將不勝感激！

沒有人有什麼想法嗎？如果可以的話請幫忙。 – Mark7777G 2010-10-30 16:44:14

對不起，我在這裏有點忙。我也可以推薦你嘗試複製並粘貼到gamedev.stackexchange.com這個問題？它會得到更多的遊戲意見:)道歉。 – 2010-11-04 09:31:54

也試過了，謝謝。 – Mark7777G 2010-11-08 01:10:32
