Python 3 Curses 程序中的一个字符 "lag"

Question

我正在尝试使用 Python3 和诅咒创建一个 roguelike。我已经按照我想要的方式显示了所有内容，但是我在代码中遇到了一个奇怪的错误。在处理命令时有 1 个击键延迟。因此，假设使用传统的 roguelike 命令，按 "k" 应该会向右移动 1 个方格。第一次按下它时，它什么也不做。第二次，它会移动。如果您随后按 "g"，您不会向左移动，而是会处理第二个 "k" 并且 "g" 结束 "on deck"。这是应该处理移动的循环。

  def main_loop(self):
#This will catch and handle all keystrokes. Not too happy with if,elif,elif or case. Use a dict lookup eventually
    while 1:
      self.render_all()

      c = self.main.getch()
      try:
        self.keybindings[c]["function"](**self.keybindings[c]["args"])
      except KeyError:
        continue

这是我自己承诺会在评论中使用的字典查找

    self.keybindings = {ord("h"): {"function":self.move_object, 
                               "args":{"thing":self.things[0], "direction":"North"}},
                        ord('j'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"South"}},
                        ord('g'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"West"}},
                        ord('k'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"East"}},
                        ord('y'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"NorthWest"}},
                        ord('u'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"NorthEast"}},
                        ord('b'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"SouthWest"}},
                        ord('n'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"SouthEast"}},
                        ord('l'): {"function":self.look, "args":{"origin_thing":self.things[0],}},
                        ord('q'): {"function":self.save_game,
                               "args":{"placeholder":0}}}

最后，这里是应该调用的 move_object 函数：

  def move_object(self, thing, direction): 
"""I chose to let the Game class handle redraws instead of objects.
I did this because it will make it easier should I ever attempt to rewrite
this with libtcod, pygcurses, or even some sort of browser-based thing.
Display is cleanly separated from obects and map data.
Objects use the variable name "thing" to avoid namespace collision."""
    curx = thing.x
    cury = thing.y
    newy = thing.y + directions[direction][0]
    newx = thing.x + directions[direction][1]
    if not self.is_blocked(newx, newy):
      logging.info("Not blocked")
      thing.x = newx
      thing.y = newy

我发现了问题，它不在我发布的代码中。它在我的 render_all() 函数中。在进行更改后，我需要添加对 window 的 refresh() 函数的调用。不得不说，我真的不喜欢骂人！
