Question

我还是python和OpenGL的新手。我写了一个简短的代码来移动汽车穿过z轴，here是我完全编写的代码，如果需要的话

我想要做的是在用户点击＆＃34; p＆＃34;时暂停游戏，在＆＃34; r＆＃34; ＆＃34; q＆＃34;然后退出程序。 ...退出工作完美但我尽管我所有的试验都不能重新启动或暂停游戏，这里是我写的部分，以考虑所有情况：

def keyboard (key,x,y):
  if key == b"q" :
    sys.exit(0)

  if key == b"r" :
    restart_program()

  if key == b"p":
    pause ()

P.S。：我尝试了Pygame的自由，但它并没有像预期的那样正常工作

任何帮助？！

See the link on my comment for a more complete way of handling pausing, but you could also just refactor your drawing code to something along the lines of:

elapsed_time = 0
paused = False

def update():
  start_time = time.time()

  if key == b"r" :
    paused = False

  if key == b"p":
    paused = True

  if paused:
    elapsed_time = time.time() - start_time
  else:
    elapsed_time = 0

  UpdateAllTheThings(elapsed_time)

while True:
  update()

Then, while updating all the moving parts of your system, you will want to scale each move by the amount to time passed. By having a separate update() function which takes elapsed time as a parameter, you can simulate pausing by passing it 0. The system of game states makes this far more robust and extensible, it's worth learning about.
