Question

我正在用Python做一个基于文本的rpg游戏，作为一个自我项目。

我在char.py文件中有一个名为Character的类，并在mapAndclasses.py文件中从中创建了一个播放器对象。对于放置在单独文件中的战斗序列，我需要从mapAndclasses.py获取Character对象。但是，我不知道如何全局使用对象。有可能这样做吗？谢谢;-; !!

Char.py

#Char.py
class character:
def __init__(self,name,job,level,exp,curHp,maxHp,mana,strength,defence,magic,baseCrit,coordsX,coordsY):
    self.name = name
    self.job = job
    self.level = int(level)
    self.exp = float(exp)
    self.curHp = int(curHp)
    self.maxHp = int(maxHp)
    self.mana = int(mana)
    self.strength = int(strength)
    self.defence = int(defence)
    self.magic = int(magic)
    self.baseCrit = int(baseCrit)
    self.coordsX = int(coordsX)
    self.coordsY = int(coordsY)

def getCharacterInfo(self):
    print("Name:", self.name, "\t\tLevel:", self.level)
    print("Job:", self.job, "\t\tExperience:", self.exp)
    print("HP:",self.curHp, "/", self.maxHp)
    print("Mana:", self.mana)
    print("Str:",self.strength)
    print("Def:", self.mana)
    print("Magic:", self.mana)
    print("Base Crit:", self.baseCrit)

mapAndclasses.py

# Load player
def loadPlayer():

saveArray = []
with open("savefile.txt") as f:

    for line in f:
        var,val = line.strip().split("=")
        saveArray.append(val)

    f.close();

global inventory
inventory = Inventory.load()

global player
# player = name, job, level, exp, curhp, maxhp, mana, strength, defence, magic, baseCrit, x, y

player = character(saveArray[0],saveArray[1],saveArray[2],saveArray[3],
saveArray[4],saveArray[5],saveArray[6],saveArray[7],
saveArray[8],saveArray[9],saveArray[10], saveArray[11], saveArray[12])

# playerCoords = [row,column]
# player always starts from the left
global playerCoords
playerCoords = [player.getCoordsX(), player.getCoordsY()]

print("\nWelcome back " + saveArray[0])

Answer 1

在同一目录中创建一个新的空文件__init__.py。（这只是将该目录标记为包，即告诉Python它可以从此处提取导入内容。）
在fightSequence.py的顶部或您所说的任何位置，通过编写以下内容来导入变量：import mapAndclasses.py。
通过引用变量来使用变量，例如mapAndclasses.variableName。

Answer 2

创建一个新的Python文件，例如vars.py，并将所有变量放在此处。

然后import vars，它将是全局的。希望对您有帮助！

如何在python中全局使用对象？
