Java TV Board Game/Grid + Moving objects

[Massaslayer]

Hello!

Does anyone have a tutorial or some tips on making a grid in java where it is possible to select objects via the keyboard and move them to other positions in the grid.

And check if the move is a valid move so you have to be able to track the item on the board.

Kind regards.

That's a pretty specific request, so you'd be lucky to find a tutorial on exactly that. But in general, what you're talking about is two steps. The first is to write the logic for check whether a move is valid. You can do this with a command-line interface, or just by hardcoding board moves. The second step is to write the KeyListener logic.

I tried to specify my "vision"

Move in the grid using the arrow keys (up down left right) then when you get to a position you need to press "enter" to select it then the object should be highlighted and you should be able to move to another position that is "empty" place on the board and then press enter again.

When you "drop" you need to check if your move is valid this means that you can't move to an empty space more then 2 block aways.

I tried to draw it:



The "O" can only be placed in place "1" and not in "2"


All the output is via JavaTV to make it extra harder

Do you have an java source code that you are having a problem with?

I know what to make sort of but I need examples:

I think I need GridLayout & keyboard listener but no clue on how to select elements etc.

how to select elements etc.

What would indicate if an element is selected or not? Some components display differently when selected.

Like I said, your first step should be to do this without a GUI at all. Use a command line interface or simply hardcode moves, and write the logic for determining whether a move is valid, what happens when a move is done, etc.

After you have that working, only then should you worry about the GUI. Taking this approach will save you a ton of headaches in the long run.
