因此，我創建了一個非常簡單的平臺遊戲，我希望平臺隨機生成，以便每個遊戲都是獨一無二的。但是，我不確定如何完美地做到這一點。我設法得到了一些實際上在屏幕上生成隨機矩形的工作代碼，但我不確定如何製作，以便「角色」能夠在它們上面移動，並且不會經過或不經過。這是我迄今爲止所做的一切代碼。現在它並不漂亮，但當我知道一切正常時，我會把它整理好。在此先感謝您的幫助:)生成隨機矩形
P.S.我也註釋掉相關的隨機長方形的東西，因爲他們完全填滿屏幕，我看不出這是怎麼回事：P

看看內置[幾何API]（http://docs.oracle.com/javase/tutorial/2d/geometry/index.html）它具有允許您繪製和檢查collesions的功能.. – MadProgrammer
請創建一個[簡短，自包含的正確示例]（http://sscce.org/）。這是一個問題太多的代碼，沒有人會閱讀所有這些。即使我有時間，根據原則，我拒絕讀取調用其類'aa'，'ab'，'ac'，'ad'的代碼（除非我的老闆強迫我）。 – Amadan
@Amadan抱歉，這是我第一次在這裏發表帖子。我刪除了前兩個班，因爲它們與問題無關。我只叫他們aa，ab等，因爲我不能想到更好的名字給他們哈哈。 –
