Java puzzle game code


The towers of hanoi is a puzzle invented in 1883 by the mathematician Éduard Lucas.    The above-mentioned legend was nothing more than an advertising invention of the same creator to attract people’s attention.

It consists of a set of 8 discs (in reality it can vary from 1 to n discs) of increasing radius that are stacked in one (the first) of the three towers of the game. The goal is to move the entire stack of disks from the initial tower to one of the other two towers (usually the last one) taking into account the following restrictions:

To make the configurations (to modify number of disks, speed in which the animation is made and algorithm used) we will have to go to Options -> Configuration. A dialog like the following one will appear:

Puzzle code in java

Some time ago I was asked for the source code of a Neon Genesis Evangelion Puzzle game, this game is complete, it has sound, gameplay log, you can load different sets of images using XML, etc, however being so complete it contains many lines of code and also many classes, in addition to make use of some external libraries, all this makes that its study is much more extensive and complicated for novice programmers, so I consider much better to leave them a much simpler and much more understandable project but no less interesting, at the end of the day what interests to know is how to program a puzzle, and whoever wants later can add sound, counter moves and other add-ons that see fit.

When you click on a square, it looks for a free space (empty square) where to move, if it finds it, it moves to that position updating the positions of the squares stored in the variable “pos_game”, if there is no free position, it stays where it is, the game ends when the puzzle is finished, that is when the variables win and pos_game are equal.

Game of 15 in java

In this post we see a way to create a puzzle game in java without the use of java2d, besides, the pieces of the puzzle will not be the typical rectangular ones but they will have an irregular shape, for this the best is to use images with a transparent background, besides to be able to move the pieces easily, we will use Absolute Layout, it is a simple example, there will be no level of complexity, there will be no score or anything like that, it is a simple puzzle game.

To create the puzzle we will start from an image *.PNG of 500×450 pixels which using an image editor, we will divide into 9 parts with irregular shape (the dimensions of each piece does not interest us), we will save the 9 pieces on disk with *.PNG format and transparent background, for example “asuka1.png, asuka2.png, etc”.

The operation of the game is very simple, we have a Piece class that extends from a JLabel which will be implemented in the Board class where we will create a 3×3 matrix, the Board class extends from a JPanel. We will make use of the Absolute Layout library to be able to position the pieces anywhere on the board, including one on top of the other.

That’s why you should take the time to play these programming games and challenges. Not only do they serve as fun breaks, but you’ll learn faster and retain more information through practice and hands-on experience. Ready to get started? Here we go.

Robocode is a complex programming game that lets you program robot tanks and pit them against each other. Your job is to write the artificial intelligence that drives your robots to success, using real languages like Java, Scala, C# and others. To get started, take a look at the Robocode basics and tutorials on Robowiki.

The Robocode installer comes with a development environment, a built-in robot editor and a Java compiler. Despite being released in 2000, Robocode is still regularly updated and maintained, thanks to the fact that it is open source and addictive.

Codecombat is another web application for puzzles and game-like challenges that can only be solved by writing code. But while Codingame is more fun, Codecombat has a significant educational side with a “Classroom Edition” that teachers can use to help their students learn to program. There are three course paths to follow: Computer Science, Web Development, and Game Development.
