The class should probably be made final unless you create it for extension. Please use at least a white line between import statements and the class declaration. I'll handle the lines in order, skipping many, with the remarks below the code. The Java 2D games tutorial is suitable for beginners and intermediate programmers.

With the removal of movecount (see below), you'd have just two fields: currentGrid and goalGrid, both of type Grid. In this tutorial, you will learn the basics of 2D game programming in Java. Smaller classes should generally be preferred when they make sense. Especially when separating out the Grid the game code will be significantly reduced. I'd create a separate class for Grid and Position at the very least.

Throw new IllegalArgumentException('Invalid size') įor (int x = 0 x 0.25 & num 0.5 & num 0.75) įifteenPuzzleViewer fpv = new FifteenPuzzleViewer(p) Private final int goal // the tile positions in the goal state Private final int size // the number of tiles across and down Private int xspace // xspace,yspace are the current coordinates of the space The default size is 4, hence the 15 puzzle name, but my 15 puzzle accepts any size (within reason). The grid goes green when it is reordered in ascending order with the 'blank tile' being at last spot on the grid. The grid is scrambled and then the user has to click tiles either next to or above the 'blank tile' to swap their places. The basic gist is to get a grid of equal width and height (size) and number them in ascending order, with the exception of the last square getting a 0 value ('0' integer not shown on the tile so it looks like a blank tile).
