我会问JPanel和paintComonent。我想用Pawns创建Ludo游戏。我试图在游戏类中使用buttonPanel（负责按钮）（对整个逻辑做出响应）。油漆 - 用于打印和保持球员和Pawns的球员。在类buttonPanel中，我用JButton创建了一个名为createDiceBtn的动作监听器，用于滚动骰子和改变玩家的位置。在玩家中，我定义了方法移动，用于在方法initCoords中移动一系列声明的坐标（坐标比坐标更少，但杂乱更少）。我已经创建了按钮，我试图在Game类中重新绘制它。数组的索引正在发生变化，但我对使用重绘有点困惑，因为它不起作用。一般来说我有这种行为的问题[类游戏是保持Paint类和按钮面板。逻辑在游戏中。如果我在游戏中按下逻辑按钮，那么它将在Paint Class中重新绘制。这是什么原因？ PS。 Sory对于非封锁，首先我希望它能够起作用。

答案 0 :(得分：0)
尝试在repaint()组件上调用Paint，而不是buttonPanel。
