角色生成

• One character generation Command to set the "Power" on the Character.
• A chargen CmdSet to hold this command. Lets call it ChargenCmdset.
• A custom ChargenRoom type that makes this set of commands available to players in such rooms.
• One such room to test things in.
  房间带了个命令，所以角色在这个房间可以执行，另一个房间不可以。

战斗系统

# announce
message = "%s +attack%s with a combat score of %s!"
caller.msg(message % ("You", "", combat_score))
caller.location.msg_contents(message % 
                                     (caller.key, "s", combat_score),
                                     exclude=caller)

NPC系统

from evennia import create_object
    
class CmdCreateNPC(Command):
    """
    create a new npc

    Usage:
        +createNPC <name>
