我試圖用Python3和curses創建一個roguelike。我已經把所有的東西都顯示出我想要的樣子，但是我在代碼中遇到了一個奇怪的錯誤。處理命令時有1個關鍵衝程延遲。所以，假設傳統的roguelike命令，按「k」應該讓你向右移動1個方格。第一次按下它時，它什麼也不做。第二次，它會移動。如果您按下「g」鍵，則不會移回左側，而是將第2個「k」處理完畢，並將「g」結束於「甲板上」。這是應該處理這些動作的循環。Python 3中的一個字符「滯後」Curses程序
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
這裏是字典查找我答應過自己我會在評論
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}}}
最後使用，這裏是一個本應被稱爲move_object功能：
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
