[Blackjack] Weird Money (Bug?)
Alright, so I'm calculating whether the last hand was won, lost, or pushed based on if my $result["money"] went up, down, or stayed the same from the last hand. Simple stuff.

I calculate whether it's a win or loss before I call MakeBet(), but it's OK because the hand is over and the money is correct. However, every once in a while (I can't distinguish a pattern) the money will change right after MakeBet().

Yes, I'm taking into account that I'm losing money betting. Here's some simple code:

php Code:
Original - php Code 
  1. $lasthandmoney = $result["money"];
  2. $result = MakeBet($bet);
  3. $thishandmoney = $result["money"] + $bet;


So $thishandmoney and $lasthandmoney should be the same, right? And it usually is, except for every once in a while... For example, I had $1000, bet $1, and won. $lasthandmoney equals $1001, but $thishandmoney, after betting another $1, then equaled $1003!

At first I thought it was my script, but I added a couple lines in miniplay.php, and I'm getting the same thing. Any ideas?

If you're trying to find out if you won or lost why not just look at the cards?

Funny Money...

Just looked thru it all - think I worked out what's happening

You got a BlackJack but it didn't add the winnings in until you called MakeBet

Well, I COULD look at the cards... money's a little simpler. Whatever.

And I thought about the Blackjack thing, but I have the script printing whenever it hits or holds. I've seen it hit once, then hold at 20, and the bug occurs. Unless 20 is blackjack. ;)

Oops... that's me, being anonymous. Here's an example I just ran: bank's at $1002, and I bet $1. I hit twice, and stand at 19, winning the hand. Thus, I should have $1003. But after MakeBet, I have $1005.

ha! I think you got it, tchala. It finds the $lasthandmoney, then calls MakeBet(), but if you get blackjack, it'll count it as a win and add the money before $thishandmoney is called. That's what it is... thanks.

[Blackjack] RE: Weird Money (Bug?)
First off looking at the cards is easy. Pinch Matt's BestVal() from blackjacklib.php and call it summat else (or write yer own)

php Code:
Original - php Code 
  1.  
  2. $his=MyBestVal($result["dealercards"]);
  3. if($his>21) $his = 0;
  4. for($i=0;$i<count($result["yourcards"]);$i++) {
  5.   $mine=MyBestVal($result["yourcards"][$i]);
  6.   if($mine>21) $mine = 0;
  7.   if($his>$mine) {
  8.     // I lost
  9.   } else if ($his==mine) {
  10.     // A draw
  11.   } else {
  12.     // I won
  13.   }
  14. }


Or summat along those lines

I'm doing a little test or 3 on the funny money thing - ley u know later

The funny money thing is potentially quite bad as you're never sure how much you have and this may affect your betting at some point - looks like it's bet * 1.5 atm but with splits etc could be higher

It's not strange nor a bug. If you would check $result["status"] right after betting, you would see "HANDOVER" and conclude you had a BlackJack.

I agree it looks strange though when you look a it without this check...

At the end of the hand the status is always HANDOVER

HANDOVER don't mean you got a blackjack, it means the hand is over

true, but if you make a bet, and immediately after that the status changes to "HANDOVER", you know it must have been a Blackjack.

But to end all misunderstandings, i think it's best to count your money each time status is "HANDOVER", after each turn...

Counting it myself ain't a lot of good. Try going to your bank manager and saying 'I know I got $10 more in my account' - you won't get very far

The take the worst concievable problem - sod all chance of it happening - two winners are within $X * 1.5 at the end and the looser's last hand had a blackjack...

Matt's our Bank manager - if at the end of the game he reckons we got $999 then we got $999 (no matter what we reckon)

[Blackjack] RE: Weird Money (Bug?)
I can see exactly what's happening (dunno why yet)

The BlackJack I just trapped was actually a pair of aces so it split

At the start of the hand I've got 990, I ante up 10 and get my cards (2 aces) so I got 980 left in the pot.

It goes thru my play routine and comes out the other end with 970, the cost of the split having been deducted.

I've got A+8 and a BJ, can't see dealer quite yet

At this point state _should_ be HANDOVER but it's actually YOURTURN

I step into MakeBet() and can see everything - dealer's bust with 6,4,2,K

Dealer pays me 20 + 25 (stake back plus winnings - 1 win, 1 BJ) so I now got 1005 as he took off my 10 stake for this hand while in MakeBet()

This time it's a normal hand - I go into my playcode with a 6+2 - he's got a 3

Coming out the other side he's been dead lucky (3, 8, K), I lost that hand but the status is correctly set to HANDOVER

Everything works as expected from then on

It's definitely the BlackJack

Yep... it is. My script wasn't registering blackjacks fast enough, so I wasn't seeing the pattern. It it kind of odd seeing your bank account jump or drop by 3x your bet. I rewrote the win/loss script, too, just to avoid this problem.
