硬币通过游戏计算一致性

Question

我正在通过学​​习Python艰难的方式学习python。我在第35课，你写了一个简短的“游戏”。

从课程开始，我正在制作自己的小游戏，以扩展我对课程这一部分的理解。我正在尝试购买用于购买东西，拾取，丢弃等的硬币。我无法弄清楚如何使硬币计数保持一致（即如果你买东西，它会带走x金币，下次你去买东西时，你也只剩下其余部分了。

以下代码部分示例。我已经尝试了所有我知道怎么做的事情（这显然在这一点上并不多！）但是当再次调用该函数时（购买剑或盾牌之后），硬币计数总是会重置。

def bazaar1():
print "\"Welcome to the Hyrule Bazaar\", the storekeeper mumbles."
print "What would you like to buy? We have:\n\nSwords (10c)\nShields (10c)\nBows (10c)\nArrows (10 for 10c)\n"

bazaar_c = raw_input("> ")
if "sword" in bazaar_c:
    print "You got the Hero Sword!\n"
    bazaar1()
elif "shield" in bazaar_c:
    print "You got the Hyrule Shield.\n"
    bazaar1()
elif "leave" in bazaar_c:
    hyruletown()
elif "exit" in bazaar_c:
    hyruletown()
else:
    print "Sorry, that's not an option.\n"
    bazaar1()

Answer 1

你应该有某种玩家状态变量传递给你的每个区域＆＃39;功能。它可以像字典一样简单：

player_data = {
 'hearts': 3,
 'coins': 10,
 'items': []
}

然后将其传递给您的每个职能部门：

def bazaar1(player_data):
  print "\"Welcome to the Hyrule Bazaar\", the storekeeper mumbles."
  print '\n'.join(["What would you like to buy? We have:\n",
                   'Swords (10c)',
                   'Shields (10c)',
                   'Bows (10c)',
                   'Arrows (10 for 10c)'])

  bazaar_c = raw_input("> ")
  if "sword" in bazaar_c:
    if player_data['coins'] >= 10:
        print "You got the Hero Sword!\n"
        player_data['inventory'].append('sword')
        player_data['coins'] -= 10
    else:
        print "You don't have enough coins"
    bazaar1(player_data)
#...
