Question

我在控制台中制作一个小型游戏，持续数天。它涉及一个矿工和他的采矿追求。游戏开始时将矿工矿石和金额初始化为0.当他开采时，我的功能选择一个20到71之间的随机整数，然后将该金额奖励给他。我正在尝试将已经开采的矿石分配给我的玩家的矿石量。我有一个reoccuring错误，指出+ =是方法和int的不支持的操作数。完整的代码和跟踪如下。

代码

import pyautogui as pag
import time
import sys
import random


class Miner:
    def __init__(self, oreDeposit, moneyDeposit):
        self.oreAmount = oreDeposit
        self.moneyAmount = moneyDeposit

    def oreDeposit(self, oreAmount):
        self.oreDeposit += oreAmount

    def oreWithdraw(self, oreAmount):
        self.oreWithdraw -= oreAmount
# -------------end of ore

    def moneyDeposit(self, moneyAmount):
        self.moneyDeposit += moneyAmount

    def moneyWithdraw(self, moneyAmount):
        self.moneyWithdraw -= moneyAmount
# -------------end of money

    def oreBalance(self):
        return self.oreAmount

    def moneyBalance(self):
        return self.moneyAmount
# -------------end of balances

def miningAction():
    x = random.randint(20, 71)
    for i in range(x):
        time.sleep(0.1)
        print(i)
        oreRecovered = i
        player.oreDeposit(oreRecovered)

player = Miner(0, 0)
miningAction()
print (player.oreAmount)

Answer 1

self.moneyDeposit是对moneyDeposit方法的引用，它不能以数字递增（即使可能，也不会按照您希望的方式执行）。

你应该改变

def moneyDeposit(self, moneyAmount):
    self.moneyDeposit += moneyAmount

def moneyWithdraw(self, moneyAmount):
    self.moneyWithdraw -= moneyAmount

到

def moneyDeposit(self, moneyAmount):
    self.moneyAmount += moneyAmount

def moneyWithdraw(self, moneyAmount):
    self.moneyAmount -= moneyAmount

和其他方法类似。

TypeError：+ =的不支持的操作数类型：'method'和'int'（Python）
