Brown - NOVATARI Welcome back to Atari's Small Miracles, th}e column written for the slow and/or lazy typists in this world. Here, programs are written short enough so anybody can ty}pe them in! There are fun programs, useful programs, strange programs, and learning programs. A little for everybody will} appear in these pages. This month's theme is the player/missile graphics features the Atari computer can use. There are} four quick programs to help you exploit this feature to its fullest! I won't even try to explain player/missile graphics} here, I'll simply refer you to the many articles and books written about them. You won't have to look too hard to find so}me. Compute! publishing has put out literally dozens of good tutorials, ANALOG has put out a few, and so on. Almost every }magazine that carries Atari will have covered player/missile graphics at some point. PMEDITOR The first program this m}onth is used to help you create and change player/missile graphics. Type it in, run it, and you can work with any shape yo}u want. The image can be eight pixels wide (obviously) and twenty-four lines high. Use the arrow keys without the contro}l key to move your cursor about (i.e. the "-", "+", "=", and "*" keys move you). Press the space bar to turn on the pixel }the cursor is sitting on, unless it was already on in which case the space bar will flip it off. Note that the numbers to t}he right of the editing area are the decimal numbers of the data you have in the player. If you don't like the player yo}u are creating, you can strike the CLEAR key to erase it and start over. On the other hand, if you like your player, press} the ESCape key to quit and a DATA statement will appear with the numbers needed to re-create that image. You can use it in} PMMOVER, below, or in a program of your own. 10 GRAPHICS 0:POKE 752,1:DIM A$(2048): Z=INT(ADR(A$)/1024)*1024:Z=Z+1024*(}Z Moves cursor" 40 POSITION 17,1:?

PEEK(A);" ";:POKE D,3*(E=0):GOTO 50 PMMOVER This program is largely instructive, and serves }little purpose on its own. It simply takes a player, pokes some data into it, then moves it around at your joystick's comm}and. That is all. What it IS meant to do is show an easy way to vertically move players and missiles, through the techni}que of strings. This is a fairly simple idea that works quite well for small applications. Study the program for a while }to fully comprehend it, and don't forget to notice the zeros at the beginning and end of the player data. Those make sure t}he player won't leave a stripe of data behind it. Replace them with some other number to see what I mean. 10 POKE 82,0:}GRAPHICS 19:POKE 752,1:DI MA$(2048),P$(24),S(15,2):Z=INT(ADR(A$) /1024)*1024:Z=Z+1024*(Z255) 50 Y=Y+128*(Y<0)-128*(Y>127):GOTO 40:D ATA 1,1,1,-1,1,0,0,0,-1,1,-1,-1,}-1,0,0 ,0,0,1,0,-1,0,0 60 DATA 0,129,66,36,24,24,36,66,129,66 ,36,24,24,36,66,129,66,36,24,24,36,66, 29,0 PLAYER5 } One of the seldom used features of player/missile graphics is the fifth player option. Simply put, turning on bit 4 of loc}ation 623 (GPRIOR) turns all the missiles into one color to let them look like a fifth player if put together. PLAYER5 tak}es care of the tedium of that process, i.e. the continous poking of the four missiles to put them next to each other. POKE} the horizontal position of the fifth player into location 256 and PLAYER5 will automatically move all four missiles to the}ir appropriate places to simulate a single player. Remember that bit 4 of GPRIOR must be on and that the color of the pla}yer is controlled by location 711. 10 FOR A=256 TO 285:READ B:POKE A,B:NE XT A:A=USR(256):POKE 256,128:POKE 5326 5,255}:POKE 623,16 20 DATA 234,104,162,1,160,11,169,6,76, 92,228,173,0,1,160,0,153,4,208,24,105, 2,200,192,4,144,245,76,95,228 } VMOVER And finally a program to suit those of you who couldn't understand PMMOVER. This program is a machine languag}e player/missile graphics mover that will take any player and move it any number of bytes up or down. To do this, in your }program code the following: JUNK=USR(ADR(A$),PMADR,DIRNO) where PMADR is the address of the player you want moved and D}IRNO is the number of bytes you want your player moved down (to go up, subtract the number of lines you want it to go up fr}om 256; for example, to move up one line you would put 256-1 or 255 into DIRNO). And that is all. Your player will be qui}ckly moved to that position. It doesn't matter if it's in single line or double line resolution, VMOVER will adjust automa}tically. 10 DIM A$(67):FOR A=1 TO 67:READ B:A$( A,A)=CHR$(B):NEXT A:DATA 104,104,133,2 13,104,133,212,104,104,133,215,16}0 20 DATA 255,173,47,2,41,16,208,2,160,1 27,132,214,160,0,132,216,177,212,72,15 2,24,101,215,37,214,168,177,212,170 30 DA}TA 104,145,212,196,216,240,5,138, 230,217,208,233,200,165,217,197,214,24 0,6,230,217,208,218,208,216,96 Atari's Small }Miracles is a column that needs a regular source of small, quality programs, and that source is the readers, you!

It also switches D1 to single density. } VERIFY.....Sets write with verify. NO.VERIFY..Sets write without verify. CHK.DRIVE..Checks the configurati }on of the drive whose number is on the stack. SET.DRIVE..Reconfigures the driv }e whose number is on the stack. The variable DENSITY controls the density the drive will be set to. } The constant C/BUF should be set to either 120 (single) or 240 (doub }le) in pns-FORTH, in val-FORTH the values should be 128 and 256. If you have val-FORTHyou should change SINGLE and DO }UBLE to set the different values into the constant. } \ 32 -BSIO, single or double dlm20nov82 hex 57 variable WCMND \ type of write 1 variable DENSITY } code -BSIO \ --- 0 ,x lda, 0= not \ read or write if, 52 # lda, 40 # ldy }, else, wcmnd lda, 80 # ldy, then, 302 sta, 303 sty, 1 # lda, 301 sta, \ set th }e unit # to 1 2 ,x lda, \ get drive # and compute the clc, 30 # adc, 300 sta, \ device id 4 ,x lda, 30a sta, 5 ,x l }da, 30b sta, 6 ,x lda, 304 sta, 7 ,x lda, 305 sta, density lda, 1 # cmp, 0= if, 80 # lda, 00 # l }dy, \ single else, 00 # lda, 01 # ldy, \ double then, 308 sta, 309 sty, 0f # lda, 306 sta, \ ti }me out value xsave stx, e459 jsr, 0< \ error? if, 303 lda, else, 00 # lda, then, xsave ldx, 6 , }x sta, 00 # lda, 7 ,x sta, inx, inx, poptwo jmp, end-code decimal --> } \ 33 Percom disk control dlm12sep82 hex } code SIO \ <>---<> xsave stx, e459 jsr, xsave ldx, next jmp, } end-code 12 c-array BUFF } : SET.CALL \ ---<> 30 + 300 c! \ se }t SIO unit number 0 buff 304 ! 1 30a ! c 308 ! ; : READ.DRIVE \ < }drive #>---<> set.call 4e 302 c! \ Read drive table 40 303 c! sio ; } : WRITE.DRIVE \ ---<> set.call 4f 302 c! \ Write drive table 80 303 c! sio } ; decimal --> } \ 34 Percom disk control dlm04sep82 : CHK.DRIVE }\ ---<> read.drive 0 buff c@ 4 .r ." tracks" cr 1 buff @ } 4 .r ." step rate" cr 3 buff c@ 4 .r ." sectors/track" cr 4 buff c@ 5 spaces if ." }double" else ." single" then ." sided" cr 5 buff c@ 5 spaces if ." } double" else ." single" then ." density" cr 6 buff c@ 256 * 7 buff c@ + 4 .r ." }bytes/sector" cr ; : SET.DRIVE \ ---<> dup r }ead.drive density @ 1 = if 0 5 buff c! 32768 6 buff !

(Well, }it does, but not in normal use.) Soon, we will have a program that will allow you to send/receive this special data, called} an Exec. Until then, files that have control and inverse characters have to be altered to a format that can be transferred} from/to Compuserve. A former SYSOP of SIG*ATARI named Bill Volk wrote a program originally called CREATO.ATR (hence- the} name CREATOR), which has subsequently been modified and improved by many sig users. The most current version of this pgm i}s located in the XA3 database. When RUN, this BASIC program will generate a new pgm in LISTed ASCII format that will late}r be used to reCREate the source program you would otherwise be unable to transfer. Thus, a file ending with ".CRE" is an} Atari BASIC program that when RUN writes the original file to your disk drive. It reCREates it, if you will. A problem ari}ses if the CRE file will be larger than 12K bytes or so. Many Atari terminal programs have limited buffer sizes for download}ing, and because of this wouldn't be able to download these programs. To solve this, a program will sometimes be broken up }into several parts. Usually, these are notated in the XA by appending a letter to the file name. So, if a file is named TES }T, and it has to be in four parts, it will usually be four pieces named "TESTA.CRE", "TESTB.CRE", "TESTC.CRE" and "TESTD.CRE!}". If a CRE file is in several parts, here's how you work it. ENTER the first file (in our example: ENTER"D:TESTA.CRE") a"}nd RUN it. Then for each of the remaining parts, type NEW to clear memory and then ENTER and RUN the next part. (The NEW is#} important! ENTER doesn't clear memory first like LOAD does.) In any case, you should have guessed that the CRE file must $}be ENTERED before it is RUN. The final file that a CRE file creates may be tokenized BASIC, listed BASIC, a binary load fil%}e, or even a data file with no special format. Check the description or accompanying documentation file to see how you shou&}ld load the final file the CRE file creates.
