有人可以幫我用我的按鈕遊戲代碼？

Question

我認爲我的問題是在我的延遲方法。我的遊戲首先應該有一個綠色的按鈕，隨機會變成紅色。如果用戶按下這個紅色按鈕，他們會失去。我的代碼沒有檢測到紅色按鈕被點擊時，我認爲是因爲我的延遲方法。但最終它會在多次顯示紅色按鈕後檢測到它。請幫忙！！運行我的代碼，看看有什麼不對，請告訴我如何解決它！ （對於按鈕的圖像是在它們應該是什麼樣的標題非常自我解釋）

Answer 1

你正在做的幾件事錯在這裏。

首先，你永遠不應該從EDT調用Thread.sleep()。這將導致你所描述的行爲：你的用戶界面將變得遲鈍而且沒有反應。你可以谷歌「Java EDT」獲取更多信息，但this是一個合理的起點。

而不是（錯）使用Thread.sleep()來檢測延遲，你可能想要使用擺動計時器。更多的信息可以在here找到。

其次，您不應該從EDT加載圖像。相反，在開始時加載它們一次。

除此之外：您最好使用JPanel（Swing代替AWT），並且您應該確實修復您的格式，因爲您的代碼很難原樣閱讀！
