如何在海龟中冷却？

Question

我正在用乌龟做游戏，需要一个有冷却时间的投掷机械师。我尝试使用时间模块，但是尝试将变量分类为int()或float()是行不通的

def throw(throwcdstart,throwcd):
  if throwcd >= 2:
    throwcdstart = int(time.time())
    print('Thrown!')    #this is put here as a placeholder

throwcd = int(time.time()) - throwcdstart #this part is in a while true at the bottom, by the way

我试着在这里和谷歌上搜索，但我得到的唯一结果是discord.py

编辑：我忘了说我在代码的开头将throwcd变量设置为2

编辑2：还有其他事情发生，比如移动和敌人AI。我尝试过使用time.sleep()之类的东西，但当我这么做的时候，它会使整个游戏陷入停顿。我还没有试过math，因为它看起来很复杂

非常厚颜无耻的表述，因为问题被问得非常不明确：

def throw(throwcdstart,throwcd):
  if throwcd >= 2:
    throwcdstart = int(time.time())
    mycooldown = 0.5 # seconds <==============
    time.sleep(mycooldown)
    print('Thrown!')    #this is put here as a placeholder

throwcd = int(time.time()) - throwcdstart #this part is in a while true at the bottom, by the way
