객체 속성 증가

속성 증가

캐릭터 클래스 mygame/typeclasses/characters를 수정합니다.py

class Character(DefaultCharacter):
    # [...]
    def at_object_creation(self):
        """
        Called only at initial creation. This is a rather silly
        example since ability scores should vary from Character to
        Character and is usually set during some character 
        generation step instead.
        """
        #set persistent attributes
        self.db.strength = 5
        self.db.agility = 4
        self.db.magic = 2

    def get_abilities(self):
        """
        Simple access method to return ability 
        scores as a tuple (str,agi,mag)

        return self.db.strength, self.db.agility, self.db.magic

자신의 역할 업데이트

at_object_creation은 대상이 처음 만들어졌을 때만 실행되기 때문에 새로 추가된 수정된 속성은 기존 역할에 나타나지 않습니다.

# (you have to be superuser to use @py)
@py self.get_abilities()
<<< (None, None, None) 

기존 역할을 업데이트하는 방법:

@update self
@py self.get_abilities()
<<< (5, 4, 2)

기존 객체 대량 업데이트

어떤 종류의 초기화 방법을 수정했을 때, 다음과 같은 방식으로 이미 존재하는 모든 종류의 대상을 업데이트할 수 있다

// from evennia shell
from typeclasses.myclass import MyClass
# loop over all MyClass instances in the database
# and call .swap_typeclass on them
for obj in MyClass.objects.all():    
    obj.swap_typeclass(MyClass, run_start_hooks="at_object_creation")

혹은

@py from typeclasses.myclass import MyClass;[obj.swap_typeclass(MyClass) for obj in MyClass.objects.all()];

db에서 지속되지 않는 속성

But sometimes you want to create temporary properties (things that are not to be stored in the database but still always exist every time the object is created). Such properties can be initialized in the at_init method on the object. at_init is called every time the object is loaded into memory.

def at_init(self):
    self.ndb.counter = 0
    self.ndb.mylist = []

명령 추가

우리는 새로 추가된 속성을 얻기 위해 일반 사용자가 실행할 수 있는 명령을 추가해야 한다.

mygame/commands/command를 수정합니다.py

lass CmdAbilities(Command):
        """
        List abilities

        Usage:
          abilities
        
        Displays a list of your current ability values.
        """
        key = "abilities"
        aliases = ["abi"]
        lock = "cmd:all()"
        help_category = "General"

        def func(self):
            "implements the actual functionality"

             str, agi, mag = self.caller.get_abilities() 
             string = "STR: %s, AGI: %s, MAG: %s" % (str, agi, mag)
             self.caller.msg(string)

mygame/commands/default 수정cmdsets.py

from commands.command import CmdAbilities
// CharacterCmdSet 
self.add(CmdAbilities())

이렇게 하면abi나abilities 명령을 사용할 수 있습니다.

특정 유형의 객체에 대한 명령 추가

새 cmdSet 생성

# file mygame/commands/mycmdsets.py
    #[...]
    from commands.command import CmdEcho
    from evennia import CmdSet
    #[...]
    class MyCmdSet(CmdSet):
        
        key = "MyCmdSet"
    
        def at_cmdset_creation(self):     
            self.add(CmdEcho())

객체에 대한 명령 집합 증가

//  ， 
// permanent false ,reload 。
 @py self.cmdset.add("mycmdsets.MyCmdSet", permanent=True)

특정 대상의 명령 집합 증가

    # e.g. in mygame/typeclasses/objects.py

    from evennia import DefaultObject
    class MyObject(DefaultObject):
        
        def at_object_creation(self):
            "called when the object is first created"
            self.cmdset.add("mycmdset.MyCmdSet", permanent=True)

존재하는 대상을 업데이트하고 명령 집합을 증가

@py from typeclasses.objects import MyObject; [o.cmdset.add("mycmdset.MyCmdSet") for o in MyObject.objects.all()]

객체 유형 추가

typeclasses 디렉터리에wiseobject를 추가합니다.py

from random import choice
from typeclasses.objects import Object

class WiseObject(Object):
    """
    An object speaking when someone looks at it.
    We assume it looks like a stone in this example.
    """
    def at_object_creation(self):
        self.db.wise_texts = [
            "Stones have feelings too.",
            "To live like a stone is to not have lived at all.",
            "The world is like a rock of chocolate.",
        ]

    def return_appearance(self, looker):
        """
        Called by the look command.
        We want to return a wisdom when we get looked at.
        """
        string = super(WiseObject, self).return_appearance(looker)
        wisewords = "

It grumbles and says: '%s'" % choice(self.db.wise_texts)
        return string + wisewords

evennia reload
