Hi I am looking to make a sliding picture puzzle app.

similar to...........


Does anyone have any tips? I have some ideas and am able to move the clicked picture but there are constraints as to which images can move etc which I have not yet thought through fully.


Thanks

What you have there is a 4x4 array. Currently it look like this:

dim arrTile[4,4] as integer

X0XX
XXXX
XXXX
XXXX

By checking the array, you can see if the move is a valid one - you can only move:

1. an X adjacent to an O
2. in the direction of the O

Whether it is a picture, letters or numbers, you can still number the tiles in the correct sequence, and give the space a value of 0, -1 or whatever suits you. Then you can check the array for the right sequence to confirm it is complete.

01 00 03 04
06 02 11 10
05 08 07 09
14 12 15 13

That's what I'd do. Remember that you don't have to actually interpret which way a piece should move, because any piece that you select would only ever move to the blank area. So if you select a piece, check for a neighboring blank space and move there.

Also, to ensure that the puzzle is reasonably solvable, just do a load of random moves, after setting the tiles to the solved locations. If find that it's easier to always stick to the game rules... like a card game I'd shuffle the deck by swapping cards randomly, a rubiks cube I'd do random rotations from a solved cube - this way you always know it's possible to solve the puzzle.

To control the movement of tiles/sprites, I'd store the grid X Y values related to the sprites - so when moving a sprite, you'd set the grid position, and have the sprite move there, like a loop that shows the sprite moving when it isn't at the correct location.

Hey Mr. Imp! I've started a community project for a cool scramble picture puzzle game. I thought you might like to take a look, get some ideas and hopefully help you build your own game.

Check it out

Thanks to all of you for the help with this. I had struggled with the array advice above, so it was nice to see what you have done with your example JLMoondog. I will be asking for some more advice on the board soon so thanks in advance.
