java - Java swing 游戏 JPanel 布局辅助
问题描述
我正在制作一个游戏，它有 3 个部分到 JFrame、游戏地图、“玩家视图”：只是一个玩家移动的动画，希望以后包括不同的敌人设计，最后是我拥有的库存部分还没开始呢
就类和方法布局而言，让我的 JPanel 的所有这 3 个部分能够相互通信并根据当前情况动态变化的最佳方式是什么（当他们的瓷砖与另一个瓷砖碰撞时让玩家视图显示敌人或者如果玩家不移动，它不会更新）。
我不介意重写整个游戏，这是我的第一款游戏，希望在结构上得到一些帮助。
而且我不确定 paintComponent 的工作原理或 repaint() 方法。或者如何调用 draw(Graphics g) 来制作图形？？？
