python - 无限循环 - 当真 [Python]

问题描述

遇到无限循环的古老问题......

编写文字冒险游戏并降低游戏机制；地图和围绕它的运动。当我尝试实现其他功能时遇到无限循环问题 - 获取项目等。

下面是 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。“......”下面是问题所在。

如图所示，所有缩进都是对齐的。


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

解决方案

我浏览了您的代码并提出以下建议：

  • 确保您的ssc c e可运行。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']”，而不是多个相等条件（当您获得更多子句时会变得非常麻烦）。

  • 日志模块是您的朋友，而不是将打印语句放在您的代码中。

  • y_loc = y_loc是无操作的。摆脱它。

  • command = input("You are " + map[curr_loc]["desc"] + ' what next? ')不需要在每个子句中，将它放在 if/elif 语句链之后。
