GUId Greif!

Greetings again forum goers!

I have another question abound with plenty of obvious nooble errors I'm sure.

I am making a memory game(You know the old game where you turn over cards and try to match two in a row, and memorize previous locations etc.
) and this is the first time using Javax.swing for me. So I wanted to try and randomize the game each time you play. Thing is, I think I'm using the actionListener, or the actionPerformed calls wrong, or maybe I'm using my constrctor poorly. It isn't making much sense to me. It also could be something having to do with Java's swing GUI calling things, that I myself don't actually invoke(The stuff that happens behind the scenes) though I doubt it is that.

So after that long winded explanation here is the problem:

Each time I click a button on this game, the image changes to another randomized image, I don't want that to happen. I want the images to be randomized once, and then not be randomized again until a new game is called up, or the game is exited and reentered.

Here is the code I have..Hope its not too confusing.
(Ignore the sound stuff, I will be putting that in the game later, but wanted to get the basic construct for it set up)

memGame.java file is as follows:

Right here is your problem. Everytime a button is pressed, a new memGame is created and everytime a new memGame is created values are randomized. DOH.

There are lots of other issues too. I know your starting out, but there are some kind of basic programming mistakes. For instance in your Button class, its creating a new button everytime it is clicked. If you're a button why would you want to make a new button everytime you're clicked?

PM me and i will send you some sample code that i creaded that involves Cards, Decks and ToggleButtons. It isn't finished, but hopefully it will send you in the right direction.

Nate

Nate you rule!

I actually saw that error too after an extended period of staring at it last night, and I put the MyButton class as a subclass of memGame and that solved it. I also found out, I could have called memGame.this as a parameter to the MyButton constructor, and that would have gotten memGames data members in there, without having to call a new constructor of it. Regardless, I fixed the problem, with the former choice.

I want to say thanks so much for your help. I know how much of a pain in the butt it can be to read someone else's code...especially if not so fantastically written. I actually may PM you soon to still get that code, cause I could always use a helping hand, but for now I actually have to go to class...grr.

Thanks again!
