ДЕНПНЛ ВY МEN ЖULMER ИORIZEN ON СLINK 128 ДEMOMK STARTED AS A VERY SIMPLE ROUTINE THAT READ ЛOALA OR ТUNРAINT FILES AND DISPLAYED THEM ON YOUR Г-128 SCREEN. БS WITH MOST OF THE PROGRAMS Й WRITE, THEY START OFF AS A VERY SMALL ROUTINE AND Й DEVELOPE THAT INTO A MUCH LARGER AND SOPHISTICATED PROGRAM. ФHIS ONE GREW INTO A MONSTER OF 75 BLOCKS OF BASIC PROGRAM CODE. ГOMBINE THAT WITH 26 BLOCKS OF MACHINE LANGUAGE SOURCE CODE AND YOU NOW HAVE A FULL BLOWN DEMO MAKER PROGRAM. НACHINE LANGUAGE IS ONLY USED FOR TRANSFERING LARGE AMOUNTS OF BIT MAP DATA AND MOVEMENT OF A CURSOR ON THE BIT MAP. ФHE PROGRAM IS PUBLIC DOMAIN SO FEEL FREE TO ADD TO IT OR MODIFY IT IN ANYWAY YOU WISH. Й TRIED TO KEEP AS MUCH OF THE PROGRAM IN BASIC AS POSSIBLE. ФO GET STARTED YOU WILL NEED A PICTURE IN AN UNCOMPRESSED ЛOALA OR ТUNРAINT MED-RES FORMAT. ЖOR DOING HI-RES FILES THERE IS A LITTLE TRICK THAT Й USE. ХSE ТUNРAINT TO LOAD THE HI-RES FILE. ЧITH ТUNРAINT SWITCH TO MED RES MODE. ЩOUR HI-RES FILE WILL NOT LOOK CORRECT, BUT NOT TO WORRY. ОOW SAVE THE FILE AS A MED-RES PROGRAM. ДEMOMK ALWAYS LOADS FILES AS MED-RES PROGRAMS, YOU HAVE THE OPTION TO USE EITHER MED-RES OR HI-RES IN THE PROGRAM. УIMPLY SELECT WHICH MODE YOU WANT AND THE FILE WILL BE DISPLAYED PROPERLY. Й USE БDVANCE БRT УTUDIO IN 64 MODE TO DO MED-RES FILES. ФHIS ENTAILS ANOTHER STEP FOR ME. ФHE ББУ FILES MUST BE CONVERTED TO ЛOALA TYPE OF FILES FIRST. ФHERE ARE SEVERAL UTILITIES TO ACCOMPLISH THIS, Й USE РIXEL РACKER. ФHE ADVANTAGE TO ББУ IS Й CAN SCAN A GRAPHIC, SAVE WITH УУЦ5 AS AN ББУ HI-RES FILE. ЧHEN ББУ LOADS IT COMES IN AS A MED-RES PICTURE. ФHE LINES USUALLY NEED TO BE TRIMMED DOWN BECAUSE OF THE RESOLUTION OF MED-RES, BUT OVER ALL IT IS A QUICK WAY TO DO A PICTURE. ЩOU WILL ALSO NEED THREE FILES CALLED УГТО2, УГТО3, УГТО4. ФHESE ARE SIMILAR TO YOUR ORIGINAL PICTURE. ФHESE PICTURES HAVE A 256 PIXEL BY 96 LINE PORTION OF THE SCREEN THAT IS DIFFERENT. ДEMOPLY ANIMATES THESE SCREENS BY STARTING WITH YOUR ORIGINAL AND OVERLAYING УГТО2, УГТО3,ЇУГТО4. ОEXT YOU WILL NEED SPRITE DATA. ФHIS IS THE INFORMATION SO THE OPERATING SYSTEM CAN DRAW THE SPRITES. ФHE DEMOMK PROGRAM USES THE BUILT IN SPRITE EDITOR. ЙF YOU HAVE A FAVORITE SPRITE UTILITY, DEMOMK ALLOWS YOU TO LOAD DATA CREATED WITH IT AND INCORPORATE IT INTO YOUR DEMO. ФHE LAST FILE IS A УЙД .MUS FILE. ФHESE FILES ARE MUSIC DATA THAT IS PLAYED IN THE BACKGROUND. Й HAVE PROVIDED ONE FILE CALLED "MOMENT MUSIC.MUS". СLINK HAS A VERY LARGE LIBRARY OF SUCH FILE TO SELECT FROM. БFTER LOADING AND RUNNING THE DEMOMK PROGRAM YOU WILL BE PRESENTED WITH FOUR MENUS. ИЙЇТЕУЇЖЙМЕ,ЇЗЖШЇЖЙМЕ,ЇУРТЙФЕУ,ЇНХУЙГЇЖЙМЕ.

ФHE DEMONSTRATION FILE "DEMOPIC" IS A HI-RES FILE, SO SET THIS TO HI RES MODE. ЙF YOUR PICTURE IS A MED-RES FILE, NATURALLY YOU WILL SELECT MED-RES MODE. ЖЙМЕЇОБНЕ: ФHE DEFAULT FILE NAME OF "ДЕНПРЙГ" IS DISPLAYED. ЙF YOU PRESS ТЕФХТО, YOU WILL BE ABLE TO SET A NEW NAME.

ЧHEN YOU PRESS ТЕФХТО THE FILE NAME WILL INCREASE FROM 1, TO 2, TO 3 TO 4. ЧHEN CREATING УГТО1-4 WITH YOUR DRAWING PROGRAM YOU SHOULD KEEP IN MIND EXACTLY WHERE THE WINDOW IS LOCATED. УГТО2-4 SHOULD HAVE THE EXACT SAME 256 PIXEL X 96 LINE WINDOW. ЙF YOU VARY FROM SCREEN TO SCREEN THEN YOUR DEMO WILL NOT DISPLAY THE GRAPHICS CORRECTLY. ЦЙЕЧЇЖЙМЕ: ФHIS WILL DISPLAY THE PICTURE. БGAIN УГТО1 IS YOUR ORIGINAL, УГТО2-4 ARE VERSIONS OF УГТО1 WITH THE 256 PIXEL X 96 LINES CHANGED FOR ANIMATION. ВХЙМД ЗЖШ: ФHIS IS WHERE THE WINDOW IS ESTABLISHED AND SAVED INTO MEMORY.

ВY PRESSING THE ТЕФХТО KEY YOU ESTABLISH THE TOP LEFT CORNER OF THE WINDOW. ФHE COLOR INFORMATION AND BIT MAP DATA IS STORED IN BANK1 FOR LATER SAVING IN THE MUSIC MENU. ЧHEN YOU BUILD УГТО1 REMEMBER HOW MANY SQUARES YOU MOVE TO THE RIGHT AND DOWN. НOVE THE SAME AMOUNT ON THE OTHER УГТО'S. ЙF YOU MAKE A MISTAKE, GO BACK AND RELOAD THE FILE NAME. ЦЙЕЧЇЗЖШ: ФHIS DISPLAYES THE 256 PIXEL BY 96 LINES GRAPHIC THAT YOU MADE IN ВХЙМДЇЗЖШ. ЙF IT IS INCORRECT, GO BACK AND RELOAD WHICH EVER SCREEN YOU ARE WORKING ON. ФHIS ENTAILS PRESSING ТЕФХТО AT THE ЖЙМЕЇОБНЕ FUNCTION FOUR TIMES AND VIEWING THE FILE AGAIN. ЕACH TIME ТЕФХТО IS PRESSED AT THE FILE NAME A VARIABLE IS SET WITH THE BASIC PROGRAM. БNY CHANGE WILL MAKE THE PROGRAM RELOAD THE УГТО FILE. ЕШЙФ: ФHIS TAKES YOU OUT OF ЗЖШ ЖЙМЕ MENU AND BACK TO THE MAIN MENU. УРТЙФЕУ МПБДЇЖЙМЕ: ФHIS OPTION ALLOWS YOU TO LOAD A SET OF SPRITES THAT HAVE BEEN CREATED. РRESS ТЕФХТО AND ENTER A FILE NAME UP TO 16 CHARACTERS LONG.. УБЦЕЇЖЙМЕ: ФHIS WILL ALLOW YOU TO SAVE A SET OF SPRITES. ЧHAT EVER NAME YOU GIVE AT THIS PROMPT IS THE ONE DEMOPLY WILL LOOK FOR WHEN THE DEMO IS RAN. УРТЙФЕ #: ВY PRESSING ТЕФХТО YOU CYCLE THROUGH THE NUMBERS 1-8. ФHIS ALLOWS YOU TO SET WHICH EVER SPRITE YOU ARE WORKING ON IN THE OTHER MENUS. БФФТЙВХФЕ: ФHE INFORMATION SET IN THIS MENU IS THE INFORMATION THAT IS USED IN THE BASIC "SPRITE" COMMAND. ПО/ПЖЖ: ЙF YOU LEAVE THIS FUNCTION OFF THEN THE SPRITE WILL NOT BE DISPLAYED.

Й HAD A PROBLEM WITH THE УЙД PLAYER AND ALL OF THE SPRITES MOVING ON THE SCREEN. ЖOR SOME REASON THE PROGRAM WOULD LOCK UP. НY ANSWER WAS TO SHUT THE SPRITES OFF WHENEVER THE PLAY MUSIC OPTION WAS ACTIVATED. БLL OF YOUR SPRITE SETTINGS ARE SAVED IN AN ARRAY AND THEY WILL MOVE IN THE ACTUAL DEMO ACCORDING TO YOUR SETTINGS IN THE УРТЙФЕЇMENU.

ФHE LAST TWO OPTIONS ALLOW YOU TO EITHER EXIT FROM THE MENU BACK TO MAIN, OR EXIT THE PROGRAM COMPLETELY. Й HOPE THAT YOU WILL DO SOME FILES WITH DEMOMK AND UPLOAD THEM TO С-LINK. Й HAVE ABOUT 3 TO 4 WEEKS OF PROGRAMMING IN THE PROGRAM. ОOW THAT YOU HAVE DOWNLOADED IT, HERE COMES THE COST OF THE PROGRAM....YOU MUST DO AT LEAST ONE DEMO WITH THE DEMOMK AND UPLOAD TO С-LINK. ЗIGGLE, HEART FAILURE HUH! ФHOUGHT YOU WERE GOING TO HAVE PAY SOME BUCKS OR SOMETHING :Д Б FEW NOTES ABOUT THE DEMOPLY PROGRAM. ДEMOPLY IS THE ACTUAL DEMO PLAYER PART OF THE PROGRAM. ЙT USES ALL THE INFORMATION CREATED AND SAVED WITH DEMOMK. ФHERE ARE THREE LINES THAT YOU MAY OR MAY NOT WISH TO CHANGE. ДEPENDS ON WHICH DIRECTION YOU SET YOUR SPRITES. МINE 55: ФHIS LINES PUTS THE SPRITES ON SCREEN STARTING WITH #8 AND ENDING WITH #1. Й SET THE SPRITES TO MOVE AT A 90 DEGREE ANGLE, SO YOU MUST START WITH THE LAST FIRST. ЙF YOUR SPRITES WERE MOVING AT A DIFFERENT DIRECTION YOU MIGHT WANT TO HAVE NUMBER 1 SPRITE APPEAR FIRST. МINE 57: ФHIS LINE IS A TIME DELAY BETWEEN WHEN THE DIFFERENT SPRITES ARE PLACED ON THE SCREEN AND MOVEMENT IS STARTED. ЖOR WIDER SPACING INCREASE THE 450, SHORTER DECREASE IT. МINE 5: ФHE VARIABLE ЕР DETERMINES THE TIME DELAY BETWEEN УГТО4 AND WHEN УГТО1 IS DISPLAYED ON THE SCREEN. УГТО4 IS THE END OF THE ANIMATED SCREENS, УГТО1 WILL PUT YOUR ORIGINAL PICTURE BACK ON THE SCREEN. БN INCREASE IN THE VALUE OF ЕР HOLDS THE LAST ANIMATED SCREEN LONGER ON THE SCREEN.
