如何在opengl和pygames中使用键盘键移动立方体?

Question

我正在尝试使用OpenGL和pygames制作3d-Snake游戏。我能够生成一个立方体，并在随机位置"生成"它。但是我不知道如何使用键盘移动立方体。后来我也应该有可能添加更多的"身体碎片"，它们也朝着同一个方向移动。我希望有人能帮助我。我会发布漏洞程序，但我是一个新手程序员，所以请不要因为我的"糟糕编程"和我的英语而指责我。如果您对更多拘留有任何疑问，请随时提出。我会尽快做出回应。

谢谢

按下的键存储在key成员中，而不是存储在event对象的type成员中：

将type更改为key，当您检查按下的键时：

例如

if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT :
glTranslatef(-1.0,0,0.0)
if event.key == pygame.K_RIGHT :
glTranslatef(1.0,0,0.0)
if event.key == pygame.K_UP :
glTranslatef(0.0,0,-1.0)
if event.key == pygame.K_DOWN :
glTranslatef(0.0,0,1.0)
