我昨天发布了这个，但我没有提供足够的背景供任何人做任何正确的分析。我正在尝试制作一个纸牌游戏，我在这个网站上发布的代码（感谢所有帮助过的人）。我已编码到点按结束按钮启动由drawPhase（）函数定义的绘制阶段并在游戏循环代码结束时启动的点。我已经做到这一点，每个玩家都会抽两张牌，但由于某种原因，它试图抽出四倍的金额，因为卡片没有索引而造成崩溃。这是代码：

先谢谢你，真的很感激。
答案 0 :(得分：0)
问题似乎出现在drawPhase()函数的这一行：
hand, deck, oppHand, oppDeck = drawPhase()[0], drawPhase()[1], drawPhase()[2], drawPhase()[3]
如果你以这种方式索引，每次索引时都会再次调用该函数，导致2张牌被附加到牌组4次，而不是追加1次。
如果你想要存储在hand, deck, oppHand oppDeck中的函数的四个输出值，你可以用这一行替换上面的代码行：
hand, deck, oppHand, oppDeck = drawPhase()
此行将所有返回值存储在变量hand, deck, oppHand, oppDeck中，这样函数只调用一次。
