unhuman Posted March 13, 2018 Share Posted March 13, 2018 This code: 890 IF (MX>8)*(MX<14) THEN MX=9900 IF (MX>28)*(MX<40) THEN MX=33910 IF (MX>50)*(MX<64) THEN MX=57920 IF (MX>75)*(MX<89) THEN MX=81930 IF (MX>103)*(MX<121) THEN MX=113940 IF (MX>123)*(MX<136) THEN MX=129950 IF (MX>138)*(MX<152) THEN MX=148960 IF (MX>161)*(MX<177) THEN MX=169970 IF (MX>186)*(MX<199) THEN MX=193980 IF (MX>210)*(MX<224) THEN MX=217990 IF (MX>225)*(MX<233) THEN MX=233 Could be reworked as:1 DIM MX1(11)::DIM MX2(11)::DIM MX3(11)::MX1(0)=8::MX2(0)=14::MX3(0)=9.... You could also use data statements. 890 FOR I=0 TO 10::IF (MX>MX1(I)*(MX<MX2(I)) THEN MX=MX3(I)::GOTO 892 891 NEXT I 892 REM continue on... We have short circuited all the conditionals. Video should be working now YouTube marked it private for some reason So put the sprite positions for the robots and bats in a 2 dimensional array and check against that? Is that what you guys are saying? Something like XX(ROW,COL), Storing all the the intersection locations in that to check against. Do I have that right? And would that improve speed as well? 2 Quote Link to comment Share on other sites More sharing options...

Airshack Posted March 14, 2018 Share Posted March 14, 2018 Wow LASooner! This is really already a fairly magnificent achievement. Your rendition of the game is simply beautiful! Here's a video for any of you out there whom haven't seen the original (1982) Night Stalker game on Intellivision: Being a long-time fan of the system, I absolutely love playing Night Stalker. Definitely one of the best games on the Intellivision. LASooner has nailed the look-sound-feel of the original game. BRAVO Sir! Especially notable: Love the Intellivision running man character and the spot-on: Maze, Gun, Spiders (better actually) and Robots... to include Spot-On Robot explosions. Sweet! Pulsing beat in the background? It's here too! The original game felt sluggish on Intellivision so I really don't feel like you're too far off on the pacing. Especially since yours is written in a variant of XB. Sure, it's compiled..but hey. I encourage you to continue to refine this game and show-off what can be done with Senior Falcon's XB256+Compiler tools. Very cool of you to post the code which will not only allow others to help optimize your code but will also allow noobs to learn from your experience! Again, BRAVO! WE NEED MORE BASIC PROGRAMMERS TRYING OUT THE AMAZING TOOLS SENIOR FALCON HAS PROVIDED. You even incorporated box art into the intro screen?! You ROCK!

+OLD CS1 Posted March 14, 2018 Share Posted March 14, 2018 When converting my game from BASIC to XB I changed all of the mathematical logic statements in my IF-THENs to actual logic operators OR and AND. It will save a few bytes here and there, make it easier to read, and may even help execution speed (like that will matter when compiled, right?) So the code: 890 IF (MX>8 )*(MX<14) THEN MX=9900 IF (MX>28)*(MX<40) THEN MX=33910 IF (MX>50)*(MX<64) THEN MX=57920 IF (MX>75)*(MX<89) THEN MX=81930 IF (MX>103)*(MX<121) THEN MX=113940 IF (MX>123)*(MX<136) THEN MX=129950 IF (MX>138)*(MX<152) THEN MX=148960 IF (MX>161)*(MX<177) THEN MX=169970 IF (MX>186)*(MX<199) THEN MX=193980 IF (MX>210)*(MX<224) THEN MX=217990 IF (MX>225)*(MX<233) THEN MX=233 Could all be re-worked as 890 IF MX>8 AND MX<14 THEN MX=9 900 IF MX>28 AND MX<40 THEN MX=33 910 IF MX>50 AND MX<64 THEN MX=57 etc... Also, I spend a lot of time finding relationships and patterns, and sometimes reworking things to produce them, so I can use long mathematical formulas to produce desired results. Though I really recommend against that as it does tend to drive me bonkers and I get overly obsessed with it. So like here, spacing for your target values is 24 apart (9, 33, 57, 81, 133, ..., 217, 233) Find a way to quantify your testing ranges and you can give each range a value to multiply by 24 and add 9 ( MX=r*24+9, r=[0..10] ) Or, like I said, spare your sanity. 1 Quote Link to comment Share on other sites More sharing options...
LASooner Posted March 14, 2018 Author Share Posted March 14, 2018 (edited) Updated Rom Image Find space or make new title screen Title screen is back I took the suggestion to use variable arrays for the maze constraints and intersections, and got a lot of memory back, the speed is about the same though.

Senior Falcon had posted the opposite of this in some other message thread. That is why I went with using * for AND and + for OR because he said it saved a little bit of memory. Is that not right?

Is that not right? http://atariage.com/forums/topic/273371-4k-shortnsweet-game-contest/page-8?do=findComment&comment=3974965 That quote had to do with saving memory in the TI BASIC program that Owen was writing. I don't know if it saves memory over using the more versatile TI XB IF/THEN/ELSE format. Also, it may not save memory when you compile the program - I don't know without trying out a test program.

Airshack Posted March 14, 2018 Share Posted March 14, 2018 Many thanks to the Falconator (Aka Senior Falcon) for providing awesome BASIC extensions and Compiler tools, and for updating them and enhancing the usability of his Game Developers Toolkit! I really think if Retro fans outside the TI community get exposed to this stuff it will generate a significantly increased buzz for the platform. Maybe we can get Randy Kindig from the FloppyDays podcast to interview Harry? As usual, there’s probably minimal awareness out there regarding the amazing progress being made with TI tools and even the new hardware. Hats off to all the creatives who keep the TI-99/4A fascinating. Sent from my iPad using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Opry99er Posted March 14, 2018 Share Posted March 14, 2018 In my recent development effort (4K game) it became evident that I was going to be several hundred bytes over the limit. One thing I did was find the most commonly used integers in my program and replace them with a variable. For instance, I used the integer *1* about 35 times in my code. I simply changed all the *1* integers in the code to a variable reference, and added *O=1* to the top of the code during the variable allocation section and it saved me a ton of program space. Additionally, I did this with the length fields in all my CALL SOUNDs and also the pitch values as well. CALL SOUND(300,440,1,659,1) became: CALL SOUND(Q, A,O,E,O) This doesnt just save bytes by shortening the length of the line, it actually decreases the amount of program space overhead by defining the variable with an integer once, and then making references to it throughout the code. I dont know how much this will help when using the compiler, but I saved almost 400 bytes in a very short code listing. With your multi-statement lines and larger program size, I imagine that doing only a few of these integer replacements will make a significant impact. Just find the integers you use most, and do one... see if it helps. Quote Link to comment Share on other sites More sharing options...
LASooner Posted March 14, 2018 Author Share Posted March 14, 2018 Excuse my ignorance here, but how does a variable holding the value of 1, take up less space than the value 1? Quote Link to comment Share on other sites More sharing options...

Opry99er Posted March 14, 2018 Share Posted March 14, 2018 (edited) because program size is equated both pre-RUN and post-RUN. Once you run the program, the variable space is reserved for whatever you decide to call the variable... rather than having an integer value repeated a hundred times. All thats left is a single, 1 byte reference to the integer. I could see how this might increase speed of the program as well. Write a simple test program and try it out.

Opry99er Posted March 14, 2018 Share Posted March 14, 2018 There is one downside though... it kind of makes code readability a little rough if you go too far Quote Link to comment Share on other sites More sharing options...
Opry99er Posted March 14, 2018 Share Posted March 14, 2018 Alright, try this out... RUN program 1, then check the SIZE (in XB) then... RUN program 2, then check the SIZE (in XB) I haven't tested the results yet, but I'm pretty confident what they will be. **Note, the second program also has 1 additional line (so one more entry into the line table, plus code size) 100 CALL SOUND(300,220,1,440,1,659,1) 110 CALL SOUND(300,220,1,440,1,659,1) 120 CALL SOUND(300,220,1,440,1,659,1) 130 CALL SOUND(300,220,1,440,1,659,1) 140 CALL SOUND(300,220,1,440,1,659,1) 150 CALL SOUND(300,220,1,440,1,659,1) 160 CALL SOUND(300,220,1,440,1,659,1) 170 CALL SOUND(300,220,1,440,1,659,1) 180 CALL SOUND(300,220,1,440,1,659,1) 190 CALL SOUND(300,220,1,440,1,659,1) 200 CALL SOUND(300,220,1,440,1,659,1) 10 A=1 100 CALL SOUND(300,220,A,440,A,659,A) 110 CALL SOUND(300,220,A,440,A,659,A) 120 CALL SOUND(300,220,A,440,A,659,A) 130 CALL SOUND(300,220,A,440,A,659,A) 140 CALL SOUND(300,220,A,440,A,659,A) 150 CALL SOUND(300,220,A,440,A,659,A) 160 CALL SOUND(300,220,A,440,A,659,A) 170 CALL SOUND(300,220,A,440,A,659,A) 180 CALL SOUND(300,220,A,440,A,659,A) 190 CALL SOUND(300,220,A,440,A,659,A) 200 CALL SOUND(300,220,A,440,A,659,A) Quote Link to comment Share on other sites More sharing options...
LASooner Posted March 15, 2018 Author Share Posted March 15, 2018 (edited) Interesting 1st One: 2nd one: Guess it's worth taking a shot, I use values 1 thru 4 to define the different bullets and monsters, suppose I could start there and see what fruit it bares, thanks!

senior_falcon Posted March 15, 2018 Share Posted March 15, 2018 (edited) I tested both these and am surprised at the results: For the first one there are 23927 bytes of memory left before and after running. For the second one there are 23993 bytes left before running and 23985 left after running.(I didn't put in line 10) So there is a savings in memory, and that would be even better if you were to substitute a 1 character variable for 220 or 659 (For what it's worth, I don't think these memory savings translate to compiled XB code; I'm pretty sure there is no difference.)

Opry99er Posted March 15, 2018 Share Posted March 15, 2018 I found my biggest savings was converting larger numbers (like the durations of the music)... that got me a big chunk. It was after a conversation with Tursi that I tried substituting even my single digit integers and that yielded savings as well. Its all in how memory is allocated during the initial variable set up. If you use Notepad++, you can type in a value and search for every iteration of that value in your code. You use *1* for loops as well... like FOR I=1 TO 16 could become FOR I=A TO 16. Any place in your code that holds the integer *1* can be substituted for the variable name of your choosing. Quote Link to comment Share on other sites More sharing options...
Opry99er Posted March 15, 2018 Share Posted March 15, 2018 When I finished Markus of Marinus (but was over on my code size) I had to move it over to the PC for tweaking. I converted the BASIC listing to TIdBiT and made the adjustments. It's not quite as heavily commented as yours, but you can see how much adjusting I did to remove values and substitute them for variables. I think you have to use a value 4 times or more to justify the additional line table and code space to define the variable. This was all a big conversation I had with Tursi and some heavy testing on my end to find what worked best. In retrospect, I would have done a few things differently to create even more space, but here's the code I ended up with. Once translated, it put me at 4080 bytes of program space. // Markus of Marinus (2018) // Entry for the 4K contest on Atariage INITIALIZE: Q=1 // this is the level number AND the seed for each level LI=15 // this is the variable for "Lives" BO=104 // this is the blacked out border character B=120 // this is the door character MN=105 // this is the monster graphic KY=112 // this is the key graphic DU=128 // this is the player character graphic SP=32 // this is the replacement for the integer "32" H=2 // this is the replacement for the integer "2" U=24 // this is the replacement for the integer "24" J=300 // this is the replacement for the integer "300" HJ=150 // this it the replacement for the integer "150" E=165 // this is the replacement for the integer "165" Y=16 // this is the replacement for the integer "16" O=659 // this is the replacement for the integer "659" D=294 // this is the replacement for the integer "294" V=587 // this is the replacement for the integer "587" F=1 // this is the replacement for the integer "1" CALL CLEAR CALL SCREEN(H) CALL CHAR(BO,"FFFFFFFFFFFFFFFF") CALL CHAR(MN,"") CALL CHAR(KY,"00E0A0BFA5E50100") CALL CHAR(B,"7E6642424A42667E") CALL CHAR(DU,"3C3D19FF98982424") // MAKE SETS 3-8 WHITE (TEXT) FOR T=3 TO 8 CALL COLOR(T,Y,F) NEXT T // Title screen goes here // TITLE: PRINT " MARKUS OF MARINUS": : : // Music Goes Here GOSUB MUSIC PRINT " PRESS ANY KEY TO BEGIN" KEYCHECK: CALL KEY(0,K,S) IF S=0 THEN KEYCHECK // TOP OF OUTER LOOP // Q IS THE LEVEL SEED WHICH IS USED TO GENERATE MAPS, ITEMS, AND MONSTERS // PR and PC are the starting row and column of the player // DK is door key (start every level without it) // PLS is the Possible Level Score (starts at 100, and subtracts 20 for each monster hit) OUTERLOOP: RANDOMIZE (Q) PR=23 PC=3 DK=0 PLS=100 // BLACK OUT THE CHARACTERS SO YOU CANNOT SEE THEM POPULATE CALL CLEAR CALL COLOR(11,H,F) CALL COLOR(12,H,F) CALL SCREEN(H) // WRITE THE LEVEL ONSCREEN FOR DISPLAY PURPOSES RESTORE LOADDATA FOR K=F TO 13 READ P CALL HCHAR(U,K+7,P) NEXT K IF Q>9 THEN DOUBLEDIGITS CALL HCHAR(U,22,Q+48) GOTO MAPGEN // IF THE LEVEL NUMBER IS A DOUBLE DIGIT NUMBER, USE THE FOLLOWING LINES OF CODE DOUBLEDIGITS: CALL HCHAR(U,22,49) CALL HCHAR(U,23,Q+38) // GENERATE THE MAP PROCEDURALLY USING THE LEVEL SEED MAPGEN: FOR I=F TO 80 GOSUB GENRAND RR=INT(RND*5)+F CALL HCHAR(R,P,BO,RR) NEXT I // GENERATE THE KEY CALL HCHAR(R,P+H,KY) // GENERATE THE DOOR GOSUB GENRAND CALL HCHAR(R+F,P,B) // GENERATE MONSTERS ON THE SCREEN, THEY WILL BE TRANSPARENT IN COLOR (SNEAKY) FOR X=F TO 15 GOSUB GENRAND CALL HCHAR(R+F,P+F,MN) NEXT X // GENERATE PLAYER CHARACTER GOSUB REDRAW // DRAW THE BORDER CALL HCHAR(F,F,BO,SP) CALL HCHAR(U,F,BO,SP) CALL VCHAR(F,F,BO,U) CALL VCHAR(F,SP,BO,U) // GIVE THE KEY AND THE DOOR A COLOR, COLOR THE SCREEN PURPLE CALL COLOR(11,11,F) CALL COLOR(12,8,F) CALL SCREEN(6) // THIS IS WHERE THE MAIN GAME LOOP WILL BE.
