ÄOES ANYONE KNOW HOW TO CONFINE THE MOVEMENT OF THE MOUSE TO STAY WITHIN THE
BOUNDRY OF A DIALOG BOX? É CAN CONFINE THE MOUSE OUTSIDE A DIALOG BOX BUT NOT
WITHIN. É MUST BE MISSING SOMETHING. ÁNY HINTS OR TIPS IN THIS AREA WOULD BE
APPRECIATED!

ÄENNIS,
   É CAN'T RECALL IF É'VE EVER TRIED TO RESTRICT MOUSE MOVEMENTS TO WITHIN A
DIALOG BOX AREA, BUT IT SHOULD WORK THE SAME AS WHEN OUTSIDE A ÄÂ.
 
   ÉN YOUR DEFINITION FOR THE DIALOG BOX ADD A CALL FOR YOUR OWN MODIFIER CODE
WITH:
 
   .BYTE   ÄÂ_ÕÓÒ_ÒÏÕÔ
   .WORD   ÙOUR_ÒOUTINE_ÎAME
 
 
   ÉN YOU ROUTINE, SIMPLY:
 
ÙOUR_ÒOUTINE_ÎAME:
   ÌOADÂ   MOUSEÔOP,ÙOUR_ÄÂS_ÔOP_ÅDGE
   ÌOADÂ   MOUSEÂOTTOM,ÙOUR_ÄÂS_ÂOTTOM_ÅDGE
   ÌOAD×   MOUSEÌEFT,ÙOUR_ÄÂS_ÌEFT_ÅDGE
   ÌOAD×   MOUSEÒIGHT,ÙOUR_ÄÂS_ÒIGHT_ÅDGE
   RTS
 
   ÔHIS SHOULD WORK.
   ÉF É RECALL THE USE CORRECTLY, THE MOUSE SHOULD REMAIN WITHIN THE WINDOW
SPECIFIED AND ON AN ATTEMPT TO MOVE BEYOND THOSE BOUNDARIES, A CALL IS MADE
THROUGH MOUSEÆAULTÖEC ($84Á7).
   ÙOU SHOULD ALSO BE ABLE TO DETERMINE WHAT TYPE OF FAULT OCCURRED BY CHECKING
THE VALUE OF FAULTÄATA ($84Â6).
   ÔHE CONSTANTS TO USE ARE:
 
   ÓÅÔ_ÏÆÆÔÏÐ       == %10000000
   ÓÅÔ_ÏÆÆÂÏÔÔÏÍ    == %01000000
   ÓÅÔ_ÏÆÆÌÅÆÔ      == %00100000
   ÓÅÔ_ÏÆÆÒÉÇÈÔ     == %00010000
 
   ÇENERALLY, YOU WOULDN'T HAVE TO WORRY ABOUT THESE.
   ÙOU ALSO DON'T NEED TO WORRY ABOUT RESTORING THESE VALUES, SINCE THEY ARE
PRESERVED BY THE SYSTEM AND RESTORED UPON ÄÂ EXIT BY THE SYSTEM.
 
   ÉF THERE IS ANYTHING ELSE YOU MAY NEED HELP ON (OR IF THIS DOESN'T WORK),
FEEL FREE TO ASK.

ÊOE -- ÔHANKS FOR YOUR TIMELY REPLY. ÔHAT IS WHAT I HAVE BEEN TRYING TO DO,
WILL REEXAMINE MY CODE AND TRY AGAIN. É CAN GET THAT TECHNIQUE TO WORK OUTSIDE
OF THE ÄÂ BUT IT SEAMS TO NOT WORK IN THE ÄÂ. É AM USING ÇÅÏÓ 128 - 2.0 AND AM
EXPERIMENTING WITH COLOR ON THE 80 COLUMN SCREEN. É HAVE REDUXCED THE SCREEN TO
176 PIXEL HEIGHT. ÈOWEVER THE MOUSE AT TIMES THINKS IT IS STILL 200 PIXELS AND
BLINDLY WANDERS OF THE SCREEN AND INTO THE COLOR ATTRIBUTE MEMORY. ÍAKES FOR
SOME VERY INTERESTING UNINTENDED COLOR EFFECTS. É'LL POST A NOTE AND LET YOU
KNOW HOW É DID.
 
ÁS SOON AS É GET AROUND TAHT BUG É'LL HAVE A NICE GEOS PROGRAM FOR UPLOAD.
ÔHANKS AGAIN!

ÄENNIS,
        É LOCATED THE TROUBLE.
        ×HEN YOU USE A DIALOG BOX, ANY TIME YOU HAVE A SYSTEM ICON IN USE, THE
VALUE OF MOUSEÂOTTOM ($84Â9) GETS RESET TO 199 ($Ã7).
        É TRACKED THIS DOWN TO THE CALL ÄOÄLGÂOX MAKES TO ÄOÉCONS WHICH, IN
TURN CALLS A SMALL INTERNAL ROUTINE TO RESET THE VALUES OF MOUSEÔOP,
MOUSEÂOTTOM, MOUSEÌEFT, AND MOUSEÒIGHT TO THEIR MAXIMUMS.
        ×HY?  É HONESTLY CAN'T SAY.  ÔHE MENU HANDLER ALSO CALLS THIS ROUTINE.
        ÔHE EASIEST, IF NOT THE MOST GLAMOROUS, SOLUTION IS TO MAKE A TEMPORARY
PATCH TO THE KERNAL TO PREVENT THIS.
        ÁT THE START OF YOU PROGRAM, PRESERVE THE CONTENTS OF THE BYTE AT $ÆÂ64
(WHICH IS 199, OR $Ã7).  ÔHEN SIMPLY LOAD THIS BYTE WITH THE MAXIMUM YOU WISH
TO WORK WITH.  ÍY PROGRAM ASSUMES A DEFAULT MOUSE POINTER, SO É USE 169 ($Á9).
        ÊUST BE SURE TO RESTORE THE ORIGINAL VALUE BEFORE EXITING YOUR PROGRAM.
        ÌET ME KNOW HOW THIS WORKS.

BEHAVED. É ALSO DID A LITTLE LOOKING WITH GEOÄEBUGGER AND É BELIEVE THE
LOCATION TO CHANGE FOR ÖER. 1.4 ( ACTUALLY 1.3 IN THE KERNAL) IS $FB67. ÈAD TO
PUT A LITTLE CODE IN FOR PRGRAM TO CHECK WHICH KERNAL IT WAS RUNNING UNDER AND
PATCH ACCORDINGLY. ÙOU ALSO HAVE TO UNDO YOUR PATCHING AS YOU LEAVE THE
PORGRAM!! ( É FOUND THAT OUT THE HARD WAY!)
 
É'M STILL 'SHAKING' FROM HAVING TO INVOKE POWERFUL MAGIC ON THIS PROGRAM.
ÔINKERING WITH THE KERNAL IS NOT FOR THE FEEBLE OF HEART!
 
ÁGAIN MANY, MANY THANKS FOR YOUR HELP!

IT UP! :)
   ÙUP, IT DOES COMPLICATE THINGS CHECKING WHICH KERNAL VERSION YOU ARE
RUNNING, BUT SUCH THINGS ARE STRAIGHTFORWARD IN EXECUTION.
   ÒESTORING TEMPORARY PATCHES LIKE THIS IS ESSENTIAL TO KEEPING AN EVEN KEEL!
   ÂÔ×, WHAT KIND OF GAME IS THIS GOING TO BE?  ÊUST CURIOUS.

ÉF YOU MUST KNOW..... <SMILE> ÉTS A SLOT MACHINE SIMULATOR. ÂUT ÉVE REALLY HAD
SOME FUN MAKING THIS THING ABLE TO RUN ON ÇEOS 64 AND 128 AND THE 80 COLUMN
SCREEN. ÃALL AN EXERCISE IN COMPATIBLE PROGRAMMING. ÉT ALSO MAKES EXTENSIVE USE
OF COLOR TO BRIGHTEN THINGS UP. ÁND LAST BUT NOT LEAST THERE IS A SOUND EFFECT
-- THE BELL RINGS WHEN YOU WIN!
 
ÉTS A SILLY LITTLE PROGRAM BUT IT HAS BEEN A GOOD LEARNING EXPERIENCE. ×ITH
SOME LUCK, A LITTLE FINAL POLISHING I SHOULD BE ABLE TO UPLOAD IT WITHIN A WEEK
OR SO. É'M HAPPY WITH IT NOW THAT THE MOUSE DOES NOT WANDER OFF THE BOTTOM OF
THE 80 COLUM SCREEN. ÔHANKS AGAIN!

ÄENNIS,
   ÊUST FOR CURIOSITY'S SAKE:  É ASSUME THERE IS NO IMPROVEMENT THAT GAINING
THE 16 SCANLINES MIGHT HAVE?
   ×HEN É WROTE ÐARALLAX, IT WAS ORIGINALLY A 40 COLUMN MODE/COLOR, USING
SPRITES FOR A 'STARTBURST' EFFECT.
   ÔHEN É SAID "ÌET'S MAKE AN 80 COLUMN VERSION", AND NEEDED TO TOTALLY REWRITE
THE COLOR HANDLER.
   ÔHEN É SAID "ÌET'S PUT 40/80 COLUMN COLOR IN ONE VERSION".  ×HAT A PAIN! É
HAD TO REWRITE THE COLOR HANDLER AGAIN, SO É COULD HAVE THE SAME CODE DRIVE
BOTH VIDEO MODES (TO CUT DOWN CODE SIZE).
   ÔHE GAME IS PLAYED ON A 19X10 GRID, BUT WITH 80 COLUMN COLOR, THE LOSS OF
THE 16 SCANLINES FORCED ME TO REDUCE THE GRID TO 19X9.
   É THEN REREWROTE (!) IT SO THAT IT WOULD DETECT THE PRESENCE OF A 64Ë VIDEO
ÒÁÍ CHIP SET AND USE THE EXPANDED 640X200, 8X8 COLOR CELL VIDEO MODE, GIVING ME
A GOOD SIMULATION OF THE 40 COLUMN SCREEN.
 
   ÉF YOU HAVE ANY MORE PROGRAMMING QUESTIONS, PLEASE ASK.
   É MUST SAY THAT É ENJOYED THIS EXCHANGE QUITE A BIT.  É HAVE LET MY ÇÅÏÓ
PROGRAMMING SKILLS GET A BIT RUSTY, AND FOUND THIS INVESTIGATION REFRESHING.
   ÇOOD LUCK ON THE REST OF THE PROGRAM.  É LOOK FORWARD TO SEEING THE FINISHED
PRODUCT.

×ELL I WENT INTO THE PROGRAM TRYING TO DESIGN A PROGRAM WHICH WOULD RUN ON ANY
Ã64/128 MACHINE WITH ANY ÇÅÏÓ VERSION. ÓO THE EXTRA 16 SCANLINES WOULD HAVE
BEEN NICE BUT É PLANNED AROUND THEM SO É DONT REALLY NEED THEM. (ÉN FACT IT
WOULD BE NICE TO WHACK THEM OFF THE BOTTOM OF THE 40 COLUM SCREEN SO IT WOULD
BE IDENTICAL TO THE 80 COLUMN!) ÂUT THATS ANOTHER EXERCISE FOR ANOTHER DAY.
 
ÔHE PROGRAM IS FINI! ÂUT I AM GONNA PLAY WITH IT A DAY OR SO LONGER TO BE SURE
THERE ARE NO HIDDEN BUGS. ÌOOK FOR IT TOWARDS ÆRIDAY.

ÄENNIS,
   É'VE ONLY WRITTEN TWO ÇÅÏÓ 128/80 COLUMN COLOR PROGRAMS.  É, TOO, HAVE SEEN
THE INTERESTING COLOR EFFECTS THAT MOVING THE MOUSE TO THE SCREEN BOTTOM
CAUSES.
   É KNOW IN ONE PROGRAM (ÐAINTÖIEW ÉÉÉ, AN 80 COLUMN COLOR GEOÐAINT VIEWER) É
BELIEVE É DISABLED THE MOUSE POINTER, SO THAT WASN'T A PROBLEM FOR ME.
   ÉN THE OTHER (ÐARALLAX, A 40/80 COLUMN GAME), É HAD TO KEEP THE MOUSE FROM
VENTURING TOO FAR DOWN THE SCREEN WHEN USING A Ã128 WITH ONLY 16Ë OF VIDEO ÒÁÍ.
É DON'T BELIEVE É HAD ANY DIALOG BOXES POP UP AT THIS POINT, THOUGH ITS BEEN A
WHILE.
   É'LL DIG OUT THE PROGRAM AND ITS CODE AND EXPERIMENT WITH IT.
   ÉF MOUSEÂOTTOM IS DECREASED TO 175, THE MOUSE SHOULD STAY ON THE VISIBLE
SCREEN.  ÒEMEMBER THAT MOUSE POSITION IS DETERMINED BY THE 'HOT SPOT' AT ITS
TOP LEFT CORNER, SO THE MOUSE POINTER'S 'TAIL' STILL DROOPS BELOW THE VISIBLE
SCREEN.
