Card shuffling?


So I've started working on a solitaire game, however for some reason I seem to have 2 of my '0' cards, in the case of my current gfx, that's the ace of spades.
I wonder if the shuffle routine has something to do with it? Can anyone see some stupidity in the following?

I think I was shuffling a non-existing card into the deck...

Sounds reasonable.

I'd probably run that For loop multiple times to get extra shufflage. Guessing it's a one shot deal, not every frame, so even if it takes a few millisecs it's no issue.

Surprisingly, I've found that this sort of shuffle works best if done only once. Since it's shuffling every single card in the deck, it's not like a human shuffle where you miss out clumps at a time.
If you start with a stacked deck and shuffle more than once with this method, you'll see some really freaky shit happening!!

Not really sure why that is.

They may be, but it would have still taken me an hour to figure out that I needed NUMBEROFCARDS-1...

Should be MAX_CARDS = 51...

Eeeuw.. Horrible number complications!!!

I've always been one to hardcode lots of numbers. Doing this framework, I'm really trying my best to switch to using const/define values, but even still..

.. Max_Cards = 52!! It should always be 52 cards!!!

But zero is also a card in Spinal's example, so you will have 53 cards... unless you want to do MAX_CARDS - 1 everywhere which is double eeuw!

I use a list to store my cards anyway, so I do have MAX_CARDS set at 52
