Wellp，我到處找，我爲綠色，因爲他們來此..AS3碰撞檢測 - 跳躍的字符推透過落地
我最近開始使用AS3玩，因爲我想學習它，所以我開始建立一個簡單的一些平臺成交。
我想我知道我的問題是，但找到解決方案已經哈哈德半。
據我考證，這是球員位置計算/幀率的問題。在程序計算他的位置和地面之間的關係之前，角色已經走得太遠了，當它最終確認了他的位置時，它開始重新校準，使他回到零點。
我的特別問題是每個製作教程和材料的人都使用不同的標籤系統，我無法找到足夠適應平原語言這個特殊問題的任何東西。
所以請原諒我的問題，但有沒有人有機會查看我的代碼，並幫助我發現問題出在哪裏。如果（downBumping）位，我覺得它與
有關，但我正在努力弄清楚要改變什麼以及如何改變。 ：\
下面的代碼：

任何幫助，將這樣非常讚賞。我想學習，但是當我甚至不知道究竟要尋找什麼時，很難。非常感謝！
