Pygame_openGL(第一人稱視角)
---
修正後順便來鋪個地板，在移動方面可能還需要再更動
目前只有擺頭而已，移動的話可能還需要再研究， 找第一人稱視角真久，原理竟然是到線性代數最後幾章 opengl-tutorial參考公式 我們先來上扣以後再來理解原理 會覺得閃爍是版本問題沒有雙衝緩衝，pyopengl第一人稱資源少的可憐，恐怖fps?! 還是我沒找到?
if( buff==False):
buff= True
mypos_buff=direction
這邊我以為我腦袋有問題，看能不能避開閃爍，結果還是不行，y軸上下會增加卡頓，

緩衝區問題?

glutSwapBuffers() 其實這一行就可以解決了，我比較衰挑到3.6版，none沒有這個函式?
移動問題
