JavaFX游戏（四连环）

这是我的第一个JavaFX游戏教程，也是我关于JavaFX面板的第一篇博客文章。我仅用200几行代码就完成了这款四连环游戏，足以应付一个简单的游戏。我在这里使用GridPane面板对磁盘进行布局，GridPane是JavaFX布局窗格之一，但它与另一个窗格不同，因为它在行和列的灵活网格内布局了其子项。

这是有关如何设置GridPanes列和行约束的代码片段：

gridpane.getColumnConstraints().addAll(new ColumnConstraints(100,100,Double.MAX_VALUE), new ColumnConstraints(100,100,Double.MAX_VALUE),new ColumnConstraints(100,100,Double.MAX_VALUE),new ColumnConstraints(100,100,Double.MAX_VALUE));gridpane.getRowConstraints().addAll(new RowConstraints(100,100,Double.MAX_VALUE), new RowConstraints(100,100,Double.MAX_VALUE),new RowConstraints(100,100,Double.MAX_VALUE),new RowConstraints(100,100,Double.MAX_VALUE));

GridPane将具有4行4列100宽的正方形网格。

您可以享受下面的其余代码。
