我的程序轉換應該停止（通過調用stop()方法，您會看到，它的註釋標記爲//my problem starts here），當兩個矩形在同一軸上相遇時。但是由於某些原因，當不在同一軸上和當它們在同一軸上時，轉換停止。沒有語法錯誤。當兩個矩形不符合時，我的Javafx程序的轉換不會繼續播放
請幫幫我。非常感謝你。

你在期待這個代碼做，爲什麼？它在做什麼與你期望的不同？換句話說，這裏的實際問題是什麼？ –
你有沒有試過調試？它使您能夠通過逐行瀏覽並查看內存和變量的狀態來了解程序的行爲。 – Thrasher
當兩個矩形都在y軸上時，我的程序轉換應該停止。但由於某些原因，當矩形不在同一個Y軸上時，它們仍然停止。其次，我在向Stack Overflow發佈之前調試了我的應用程序。 – IbrahimLikeJava
