Tile Swapping GAME

             The little one at my home likes to play the hidden object games. There are also mini games as a part of the hidden object game. One such game I came across was tile swapper, which is of course a good old one. I thought of trying this game with MATLAB and to my surprise ,it came out better than I expected.

Method I used:

I divided the image into equal parts and randomized the position of the images.
I created push buttons and placed these random parts on it.
When a button is clicked followed by another button click, the image on the previous button click is swapped with the last button clicked image. This process continues until all the image parts are at the correct position.

How to play:

1.       Select an image from the popup menu



2.       Select the number of tiles from the popup menu

3.       Click an image part

4.       Click another image part

The selected  image parts are swapped



5.       Continue the process until all the image parts are in correct position.


6.       If the image parts are in correct position then msgbox pops up with a message.


MATLAB CODE:


function tile_swap_game
clear all;
clc
%FIGURE WINDOW
figure('Position',[250 150 700 450],'Name','TILE SWAP GAME','NumberTitle','off','MenuBar','None','Resize','off');

    end
end




NOTE:  

a. Check whether the current directory contains JPEG images before executing the code
b. If you find the code is broken or unable to execute, mail me.I will mail you the code. Happy Weekend:-)
