我試圖做一個簡單的碰撞檢測來禁用玩家移動時觸摸可碰撞對象。但是，在可能發生碰撞的地方，碰撞總是被觸發。我不知道爲什麼玩家不移動，如果玩家的中心距離可戰鬥的邊界10個像素，這個代碼只能阻止移動。我相信這種方法是錯誤的，但我想不出任何其他的螯合碰撞方式。（python + pygame）與rects碰撞檢測
您是否在閱讀本書：http://inventwithpython.com/？ –
真的，你希望我們爲你調試程序嗎？ ：o – mac
對不起，我不是那個意思。我相信代碼是錯誤的，我需要更好的方法來檢測碰撞。我的帖子缺乏，因爲我的互聯網如此緩慢，當我不小心打進輸入發送，它並沒有取消。 – Kroltan
