..^U:ZERO. BYTES: EMULATING A MOU
SE.. BY BARBARA H. SCHULAK..
WITH THE ADVENT OF GEOS, THE.POPULARITY
OF THE MOUSE AS AN INPUT.DEVICE HAS INCR
EASED DRAMATICALLY..MAINLY, IT'S THE "PO
INT AND CLICK".ENVIRONMENT THAT PEOPLE L
IKE..HOWEVER, NOT ALL USERS HAVE THE 135
1.MOUSE, OR IF THEY DO, THEY DO NOT KNOW
.HOW TO USE IT IN PROGRAMS OF THEIR.OWN
MAKING. SO, TO PROVIDE A MEANS.OF CREAT
ING PROGRAMS THAT ALL USERS.MAY TAKE ADV
ANTAGE OF, I HAVE WRITTEN.KEY DRIVER 64
AND JOY DRIVER 64 THAT.EMULATE THE PROGR
AM M1351.64.BIN.FOUND ON THE DEMO DISK S
UPPLIED WITH.THE COMMODORE 1351 MOUSE...
ALL THREE DRIVERS HANDLE MOVING.THE
SPRITE POINTER AND SHARE THE SAME.STARTI
NG ADDRESS. ALSO, ALL THREE.ROUTINES AR
E INSTALLED AND TURNED.OFF WITH THE SAME
SYS ADDRESS..THEREFORE, ONCE THE APPROP
RIATE.MODULE IS LOADED, YOUR BASIC CODE
IS.THE SAME REGARDLESS OF INPUT DEVICE..
. WHEN WRITING A PROGRAM, YOUR FIRST.
STEP IS TO ASK THE USER WHICH INPUT.DEVI
CE HE OR SHE WILL BE USING. THEN.LOAD I
N THE APPROPRIATE DRIVER. FOR.EXAMPLE,
IF THE KEYBOARD HAS BEEN.CHOSEN, THE FOL
LOWING CODE WILL LOAD.THE DRIVER. ALL T
HREE ROUTINES START.AT 49152....POKE147,

EFINITION PATTERN EITHER WITH DATA.STATE

EXAMPLE, TO LOAD THE FILE."MOUSE.SPR" TO

T STEP IS TO ACTIVATE YOUR.SPRITE:.. V=

OINTER.MUST BE SPRITE 0....... NOW YO
U ARE READY TO ACTIVATE THE.POINTER. NO
MATTER WHICH INPUT.DEVICE HAS BEEN SELE
CTED A SYS 49155.WILL TURN ON THE ROUTIN
E. ALL OF.THESE ROUTINES ARE INTERRUPT
DRIVEN..YOUR PROGRAM DOES NOT HAVE TO PR
OVIDE.CODING FOR MOVING THE POINTER..BEC
AUSE THE ROUTINES ARE INTERRUPT.DRIVEN,
HOWEVER, YOU SHOULD.DEACTIVATE THEM WHEN
ACCESSING THE.DISK DRIVE, PRINTER OR KE
YBOARD AND.WHEN YOUR PROGRAM ENDS. TO D
O THIS,.SYS 49158........ THE JOYSTIC
K DRIVER SUPPORTS THE.JOYSTICK IN PORT 2
AND ALLOWS YOU TO.MOVE THE SPRITE POINT
ER IN EIGHT.DIRECTIONS. THE KEYBOARD DR
IVER.SUPPORTS MOVEMENT IN FOUR DIRECTION
S.USING THE RIGHT, LEFT, UP AND DOWN.CUR
SOR KEYS... YOU MAY ALSO CHANGE THE S
PEED OF.THE POINTER WHEN USING EITHER TH
E.KEYBOARD OR JOYSTICK DRIVERS BY A.POKE
49175,SPEED. I WOULD SUGGEST.USING 1 (
SLOW) TO 4 (FASTER). IF THE.SPEED IS TO
O FAST, BASIC WILL NOT BE.ABLE TO KEEP U
P. DO NOT MAKE THIS.POKE IF THE MOUSE D
RIVER IS.INSTALLED.... NOW THAT THE R
OUTINES ARE.INSTALLED HOW DO YOU USE THE
M IN YOUR.PROGRAM? IF YOU EXAMINE THE C
ODE.FOR THE ACCOMPANYING DEMO PROGRAM,.Y
OU WILL SEE HOW TO FIND THE LOCATION.OF
THE POINTER IN RELATION TO SCREEN.X AND
Y COORDINATES OR SCREEN MEMORY,.OR HOW T
O SEE IF THE POINTER IS.TOUCHING ANOTHER
SPRITE. ONCE THE.POINTER'S LOCATION HA
S BEEN.DETERMINED, IT IS A SIMPLE MATTER
OF.DETERMINING WHETHER THE FIRE BUTTON.
HAS BEEN PRESSED IN THE CASE OF THE.JOYS
TICK OR IF RETURN HAS BEEN.PRESSED WHEN
USING THE KEYBOARD...... TO FIND THE
X AND Y COORDINATES.OF THE SCREEN WHERE
THE VARIABLE.V = 53248, USE THE FOLLOWIN
