我的 Java 小程序遇到问题。我做了一个石头剪刀布游戏,但有两个问题无法解决: 1.如何加载小程序而不出现左侧岩石图像(玩家选择) 2.每输一场,玩家和电脑的分数不减1

最佳答案
how to load the applet without the rock image on the left (players choice)
当玩家尚未做出选择时,您的 myValue
变量需要有第四种情况。现在您只有三个潜在值,默认值为 0,这就是为什么您在做出选择之前会看到岩石图像。
the score for player and computer does not reduce by 1 for every lost game
您在应该使用 enum
和 boolean
的地方使用了 int
,这使得您的代码更难理解。我强烈建议重构您的代码以使用 enum
和 boolean
而不是 int
。
此外,您总是从 Paint() 方法中调用每个方法。不要那样做。相反,仅在玩家实际做出选择(可能是通过单击按钮)时调用检查获胜者的函数。
最后,您还在 paint()
方法中调用 setLocation()
,这是一个坏主意。您应该只调用 setLocation()
一次,或者更好的是,使用布局管理器。
