Z-ZEE (Awfully Similar to Yahtzee)

[Moggy]

Glad to help!

@XAVSNAP

I've gone through the iterations of your code and I feel a little bad now. I am pretty sure if I had been following your post during the week I could have saved you a whole lot of time. You wouldn't have had to rewrite all those calculations after 6's if you knew S(12) was SUM and not S(7) like you thought.

OK, here are some minor improvements. So minor it is still 2.1

Z-ZEE "celebration" ever so slightly faster.

NONE now selectable with 0 like ALL is with 6

Dice Throw enumerated

Pretty darned happy with it at this point.

Hi,

I think we can make the scoring faster. Because of small straight, I added the F(6) array to redundantly store the bubble sorted values used to calculate scores. If we made it skip the bubble sort that starts at 1520 when S("SM STRAIGHT") is chosen and then make that sub do its own bubble sort, we can eliminate the F calculation for the rest of them. That way everything but small straight should be faster. It is past my bedtime now (midnight here) and your clever uses of AND and NOT are confusing me right now, so I'll revisit this tomorrow.

Booleans on the ZX81:

Code: Select all

B=0 = FALSE
B=>0 = TRUE
B=<0 = TRUE

NOT B:

Code: Select all

If B>0 then NOT B=0
If B=0 then NOT B=1
If B<0 then NOT B=0

Code: Select all

"IF B THEN" : "IF B<>0 THEN" : "IF B<0 OR B>0 THEN"

Code: Select all

"NOT PI"="NOT -PI"=0

Code: Select all

"LET B=-PI" (TRUE)
"PRINT ("HELLO" AND B) print "HELLO""

Code: Select all

"LET B=NOT -PI" = NOT ABS (-PI)" (NOT TRUE=FALSE)
Don't print "HELLO"

Code: Select all

"B=-1"
"IF B THEN PRINT "TRUE""
"IF NOT B THEN PRINT "FALSE""
"IF NOT -1 THEN PRINT "FALSE""
"IF NOT 'TRUE' THEN PRINT "FALSE""

Code: Select all

LET A$=("HELLO" AND B)+("WORLD" AND NOT B)
B=1 A$="HELLO"
B=0 A$="WORLD"

Code: Select all

LET A=(5 AND B)
B=1 A=5
B=0 A=0

Code: Select all

LET A=NOT(A$>"5" AND NOT B)
LET A=NOT(A$>"5" AND B=0)
A$="6"
B=1 A=1
B=0 A=0

It's easy, but forget the test by card D(x) array...
Just get the avalaible values !

D(1) = something... D(2) = something... D(5) = something...

But for "1", how many dices?

Code: Select all

  6000 DIM R(6)
  6010 FOR A=1 TO 5
  6020 LET R(D(A))=R(D(A))+1
  6030 NEXT A
  6035 IF S>7 THEN RETURN
  

R(1)= 1 dice with the "1" value. [1][2][3][3][3]
R(2)= 1 dice with the "2" value. [1][2][3][3][3]

if R(6)=4 then you have 4* "6" dices ! [2][6][6][6][6]

Code: Select all

GOSUB 6000
IF R(1) AND R(2) AND R(3) AND R(4) AND R(5) THEN PRINT "LARGE TRAIGHT"
IF  R(2) AND R(3) AND R(4) AND R(5) AND R(6) THEN PRINT "LARGE TRAIGHT"

(...)

Code: Select all

GOSUB 6000
IF R(1) AND R(2) AND R(3) AND R(4) THEN PRINT "SMALL TRAIGHT"
IF R(2) AND R(3) AND R(4) AND R(5) THEN PRINT "SMALL TRAIGHT"
IF R(3) AND R(4) AND R(5) AND R(6) THEN PRINT "SMALL TRAIGHT"

(...)

Your double FOR-NEXT if too heavy...

[XavSnap]

You have found so many buggs in my release... But..

Code: Select all

  1800 IF S>6 THEN GOTO 6000+(S*100)

(...)
  7000 LET V=0
(...)
  7100 LET V=0
(...)
 7200 LET V=0

2 line can be deleted, the V value isn't a global variable and is used only after these 3 jumps!
It wasn't a BUGG...

Code: Select all

  1792 LET V=0
  1800 IF S>6 THEN GOTO 6000+(S*100)
(...)
  7000 REM
(...)
  7100 REM
(...)
 7200 REM

Save memory room !

But, these routines will be updated.

Don't worry about speeding things up because the emulators can do this for you and with real zeddy the 2 speed ROM runs the game at nearly machine code speed. On my ZX81 scoring takes 2 seconds so need for more speed I would have thought.

The "NONE" button and "DICE THROW" display are a nice feature.

Made a few alterations I know Xav doesn't like the use of FAST but it does speed things up.

Code: Select all

2 SLOW   (NEEDED TO CONFIRM SLOW WHEN GAME RE-STARTED)
1501 FAST     (SPEEDS UP SCORING ROUTINE TO ABOUT A COUPLE OF SECONDS)
990 SLOW   (MOVED UP SOME LINES TO ENTER THIS TO GO BACK TO SLOW AFTER SCORING ROUTINE)
1305 PRINT AT 21 , 0 ; "ARROWS/ENTER TO CHOOSE SCORE"    ( SHORTENED THIS LINE AS THE LETTER "E" FROM THE WORD SCORE NOT BEING ERASED)

Finally got a bonus YAHTZEE and the wildcard function seems to be working, could this be the end?

The wildcard only works on the lower section of the board like in the original 1950's rules and scores zero when used in the upper section.
