类属性不会传递给对象 [英] Class attributes not passing to objects

问题描述

我试图创建一个非常基本的RPG类游戏，你选择一个角色，给这个角色的武器，然后告诉它来攻击与伤害另一个字符根据字符和武器的统计信息。在武器类属于所谓的顶层类装备。当我尝试不过来设置结合了武器的统计攻击损伤变量，我得到：

 '字符'对象有没有属性'的武器。
 

我有字符类武器值设置为无为默认值。但低于，我已经给了字符（院长）使用武器 dean.weapon =剑（这是一个武器）。我试着改变 weapon.wgt 到 self.weapon.wgt ，但似乎并没有帮助。

查看code的相关部分，而忽略了攻击 code，因为我不认为这是相关的问题，并会扰乱的事情，但我会，如果是必要的。

我相信，code是一个烂摊子，如此具有建设性的批评将是AP preciated。

code：

 类CHAR（对象）：    高清__init __（自我，名）：
        名称=名称
        HP = 300
        MP = 10
        STRN = 1
        DMG = 1
        DEX = 1
        护甲= 0
        武器=无    attack_speed = DEX    intact_bones = [右臂，左臂，右腿，腿腿，骷髅，胸骨，鼻子]＃只是假设右侧是原发性侧NOW    broken_bones = [] ###确定每个骨骼做什么，如果骨在此列表    DMG = STRN * self.weapon.wgt
类装备（对象）：
    WGT = 1
    说明=    高清__init __（自我，名）：
        self.name =名称级武器（装备）：
    影响= 1
    犀利= 1    高清__init __（自我，名）：
        self.name =名称剑=武器（亮剑）
sword.wgt = 10
sword.impact = 6
sword.sharp = 7
dean.weapon =剑
dean.attack（汉密尔顿）
 

解决方案

记住使用自如您在其他 __的init __ 方法，使实例的属性。

 高清__init __（自我，名）：
    self.name =名称
    self.hp ​​= 300
    ...
    self.weapon =无
 

另外，我觉得其他属性也应该是实例属性，也就是说，它们设置在 __的init __ 方法和使用自，例如： self.wgt ， self.impact ， self.broken_bones 等等。

I'm trying to create a very basic RPG-like game where you select a character, give that character a weapon, and then tell it to attack another character with damage based on the stats of the character and the weapon. The weapon class belongs to a top level class called Equip. When I try to set an attack damage variable that incorporates the weapon's stats, however, I get:

'Char' object has no attribute 'weapon.'

I have the Char class weapon value set to None as default. But below, I have given the character (dean) a weapon by using dean.weapon = sword (which is a weapon). I've tried changing weapon.wgt to self.weapon.wgt but that doesn't seem to help.

See the pertinent parts of the code, leaving out the attack code because I don't think it's relevant to the question and will clutter up things, but I will if it's necessary.

I believe the code is a mess, so constructive critique will be appreciated.

Code:

class Char(object):

    def __init__(self, name):
        name = name
        hp = 300
        mp = 10
        strn = 1
        dmg = 1
        dex = 1
        armor = 0
        weapon = None

    attack_speed = dex

    intact_bones = ["right arm", "left arm", "right leg", "leg leg", "skull", "sternum", "nose"] # JUST ASSUME RIGHT SIDE IS PRIMARY SIDE FOR NOW

    broken_bones = [] ### define what to do per bone if bone is in this list

    dmg = strn * self.weapon.wgt


class Equip(object):
    wgt = 1
    desc = ""

    def __init__(self, name):
        self.name = name

class weapon(Equip):
    impact = 1
    sharp = 1

    def __init__(self, name):
        self.name = name

sword = weapon("Sword")
sword.wgt = 10
sword.impact = 6
sword.sharp = 7


dean.weapon = sword
dean.attack(hamilton)

解决方案

Remember to use self, as in your other __init__ methods, to make attributes of the instance.

def __init__(self, name):
    self.name = name
    self.hp = 300
    ...
    self.weapon = None

Also, I think the other attributes should also be instance attributes, i.e., set them in the __init__ methods and use self, e.g. self.wgt, self.impact, self.broken_bones, etc.
