如何解决无限循环 - While True [Python]
遇到老问题无限循环...
编写文本冒险游戏并降低游戏机制;地图和它周围的运动。当我尝试实现其他功能时遇到无限循环问题 - 拿取物品等。
以下是 2 个代码片段,包括初始化变量、移动代码和下一阶段的内容。 “......”下方是问题所在。
所有缩进都按所见对齐。
print("Welcome to this most intrepid" + game['name']
+ " your goal; should you dare to continue... is to" + game['goal'])
star_loc = int(game['start'])
curr_loc = star_loc
character = {'inventory': [],'location':curr_loc}
x_loc = 1
y_loc = 2
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
while True:
command_parts = command.split()
cmd = command_parts[0]
print(cmd)
obj = command_parts[-1]
print(obj)
#move around map
if cmd == 'move' or cmd == 'go' or 'hiddenpath':
#handles movement on the X plane - East,West
elif obj == 'east':
if x_loc == int(game['xsize']): # use the x size the game dict instead,compute the x and y
curr_loc = curr_loc - 2
x_loc = 1
y_loc = y_loc
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
else:
curr_loc = curr_loc + 1
x_loc = x_loc + 1
y_loc = y_loc
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
elif obj == 'west':
if x_loc == int(game['xsize']) - 2:
curr_loc = curr_loc + 2
x_loc = x_loc = 3
y_loc = y_loc
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
else:
curr_loc = curr_loc - 1
x_loc = x_loc - 1
y_loc = y_loc
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
.................
if cmd == 'exit':
print('Goodbye')
break
if cmd == 'inv':
print('You are carrying')
for item in character['inventory']:
print('',item)
continue
if cmd == 'goal':
print(game['goal'])
else:
continue
if cmd == 'take':
if obj in map[curr_loc]['obj']:
print("You take the " + str(map[curr_loc]['obj'][0]))
map[curr_loc]['obj'].remove(obj)
character['inventory'].append(obj)
continue

解决方法
我浏览了您的代码并提出以下建议:
-
确保您的 sscce 是可运行的。具体来说,你没有告诉我们游戏是什么样的。
我会使用“cmd in ['move','go','hiddenpath']”。
-
日志模块是您的朋友,而不是在您的代码中放置打印语句。
-
y_loc = y_loc
是空操作。摆脱它。 -
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
不需要出现在每个子句中,将它放在 if/elif 语句链之后。
上线
if cmd == 'move' or cmd == 'go' or 'hiddenpath':
改成
if cmd == 'move' or cmd == 'go' or cmd == 'hiddenpath':
