學了這么長時間的Pygame，一直想寫個游戲實戰一下。看起來很簡單的游戲，寫其來怎么這么難。最初想寫個俄羅斯方塊，想了很長時間如何實現，想來想去，也沒寫出來，于是干脆下載別人的代碼來讀。后來，要想寫一個幫助記憶的挖寶箱的游戲，結果也沒完成。唯一完成了就是下面這個小人接金幣的游戲，超級簡單，通過左右鍵控制小人移動去接空中下來的金幣，接住金幣得5分，接不住游戲結束，金幣速度會隨著level的關數而越來越快。完成這段代碼后，我依然覺得這段代碼寫得很差，確實也是自己對pygame只是掌握了皮毛，對surface、sprite這些理解的還不透徹。這里把代碼寫出來，有時間的大牛們可以幫助指點一下，讓我也有所提高。
