基于小文本的RPG (v2)

Question

这是我制作的第一款基于文字的游戏。它很小，因为我刚学了Python，想要从小程序开始，然后编写更大的程序。从上次开始我就加了些东西。请给出你诚实的意见。

关于这个游戏，这里是我最初的问题。

设计

现在看来，要创建“阶段”，就需要创建多个函数，每个函数包含多个if语句，每个函数决定下一步将运行哪个函数或"stage“。这不是一个很好的方法，它可以使代码很难阅读。

实际上，我已经创建了一个库，并得到了一些其他用户的帮助，这使得创建这样的冒险游戏更加容易。它被称为Cactus，您可以找到存储库这里以及下载链接。您还可以访问网站。

来自官方文件：

导入--将仙人掌导入到您的项目中非常容易。将Cactus/cactus添加到PYTHONPATH后，您只需要做以下工作:导入创建cactus.Position实例的仙人掌-- cactus.Position实例存储有关cactus.Flowchart位置的相关数据。作为参考，这里有一个cactus.Position属性的列表。

• "name" -这个职位的名字。
• "desc_enter" -当玩家“进入”位置时要显示的描述。
• "desc_exit" -当玩家“退出”位置时要显示的描述。
• "choices" -表示流程图中其他位置的选项字典。键是用户输入的内容，值是流程图中其他位置的引用键。

下面是一个简单的cactus.Position实例的结构: cactus.Position({“名称”："start“、"desc_enter"：”enter on enter.“、"desc_exit"："Description on exit.”、"choices"：{ "choice1"："1“、"choice2"："2”} })，创建cactus.Flowchart实例流程图对于Cactus是必不可少的。流程图是你如何构造游戏玩家将遍历的“地图”。作为参考，这里有一个cactus.Flowchart属性的列表。

• "data" -将实际流程图数据存储为字典。

下面是一个简单的流程图实例的结构。流程图= cactus.Flowchart({“数据”：{ "position_name"：cactus.Position( .)} })创建一个cactus.Game实例cactus.Game类存储与流程图或位置无关的游戏一般数据。cactus.Game类也是存储事件处理程序和全局命令的地方。作为参考，这里有一个cactus.Game属性的列表。

• "name" -游戏的名字。
• "desc" -游戏的描述。
• "prompt" -用于输入命令的提示符。
• "invalid_input_msg" -当用户输入无效输入时要显示的消息。
• "flowchart" -已创建的流程图实例。
• "case_sensitive" -如果这是假的，那么所有的用户输入，和某些属性值转换为小写。如果这是真的，那么这一切都不会发生。
• "allow_help" -如果这是真，那么用户可以获得帮助。
• "about_text" -这个游戏是关于文本的，其中包括了需要使用的属性文本。
• "event_handlers" -事件处理程序及其相应函数的字典。
• "global_commands" -可以在任何地方执行的命令字典及其相应的函数.

下面是一个简单的cactus.Game实例的结构。cactus.Game({“名称”：“游戏名称"，"desc"：”游戏描述“，”提示“：">”，"invalid_input_msg"：“无效输入”，“流程图”：流程图，"case_sensitive"：False，"allow_help"：True，"about_text"：“在这里写你的游戏。”、"event_handlers"：{ "position.Name Goes 1.enter.after"：exit、"position.Name Goes Here 2.enter.after"：exit }、"global_commands"：{ " exit "：exit })一旦完成以上所有操作，您就可以开始游戏了。假设您已经创建了cactus.Game的一个实例，命名为GAME，并且所有的检查都被检查出来，那么您所需要做的就是下面的GAME.play_game()

去除复制

与其每次重新创建fight_enemy函数以运行不同的函数，不如在函数签名function_to_run的末尾添加一个额外的参数。然后，您的fight_enemy函数将变成如下：

def fight_enemy(enemy_name, min_enemy_damage, max_enemy_damage, min_player_damage, max_player_damage, function_to_run):
    enemy_damage_dealt = random.randint(min_enemy_damage, max_enemy_damage)
    player_damage_dealt = random.randint(min_player_damage, max_player_damage)

    if enemy_damage_dealt > player_damage_dealt:
        print("Uh-oh! You died!")
        game_over()
    elif enemy_damage_dealt < player_damage_dealt:
        print("You killed the {enemy_name}".format(enemy_name=enemy_name))
        function_to_run()
    else:
        print("You walk away unscathed, but the {enemy_name} still lives.".format(enemy_name=enemy_name))
        function_to_run()

Nitpicks

您还在许多地方使用input函数转换str调用的结果。这是不必要的。您可以这样调用input：

... = input( ... )

我也会删除各种time.sleeps，这是有点烦人的时候，必须等待游戏，特别是当它是超过1-2秒。
