Thanks for the video and pics. Are you planning on selling this one later on to many customers? http://www.ti99iuc.it/ebay/ParsecTSNera-2.jpg

I tried making another game where a plane constantly goes to the right, wraps around the screen, and the player drops a bomb on a red target that randomly covers one of the buildings on the bottom of the screen. The target is supposed to stay put until hit by the bomb, then pop up again on the same row somewhere, and maybe stop after a counter reaches 25 or whatever. How can I make the red target area(DOT) stay on the bottom line of the screen where the buildings are?(Row 24, Dot Row 185) I was thinking slightly changing the buildings string every time the plane reaches the rightmost of the screen to give the effect of moving over land. Flipping the string back and forth between 2 strings made up of the same characters in different positions. What kind of statement can I use to say whenever the plane reaches column 32, flip the building string? How can I make the bomb disappear whenever it hits row 24? 50 !*************** 60 !* CITY BOMBER * 70 !*************** 80 !11-01-11 90 !NOVEMBER 1, 2011. 95 CALL TITLE 100 CALL CLEAR :: CALL SCREEN(

What kind of statement can I use to say whenever the plane reaches column 32, flip the building string? Using CALL POSITION will tell you the position of the plane. Using the IF statement will make the flip go in action. Clever use of the function SEG$ may come in handy. orion1052003, on Mon Nov 7, 2011 11:25 PM, said: How can I make the bomb disappear whenever it hits row 24? Same as above. CALL POSITION and IF. How would you feel about a couple more questions, then I copy/paste this stuff to the public forum and any further questions posted there? My friend is on the group and I wanted to surprise him with a new program that had made a bit of progress as a surprise. If that's cool, what is the best way to handle coinc? It seems kinda shaky when I run the program, for example if I hit the target the bomb will disappear. but if I miss it will continue on its journey up and down and wrapping down the screen again. I put the coinc before the boundary check, and I may be asking for trouble by having the boundary, coincing, bottom of the screen all on the same bottom row. If I can get the "building printing" animation working, but it prints too slow, is there any way to speed things up? I've been looking at Graphicomp. The game seems to sort of work, but not smoothy or "classy". 50 !*************** 60 !* CITY BOMBER * 70 !*************** 80 !11-01-11 90 !NOVEMBER 1, 2011. 95 CALL TITLE 100 CALL CLEAR :: CALL SCREEN(

and any further questions posted there? My friend is on the group and I wanted to surprise him with a new program that had made a bit of progress as a surprise. Okay. orion1052003, on Tue Nov 8, 2011 10:24 PM, said: If that's cool, what is the best way to handle coinc? I think there should be a main game loop handling: 1. Checking fire (player will release bomb) 2. Checking coincidence (between bomb and target) 3. Checking if bomb is off screen This should be accomplished in 2-3 program lines. That should catch the coincidence most of the time or always, if the bomb does not travel too fast. Making a experimental program with not more lines than the above will let you experiment with different speeds. In this case I think I would use the ALL in COINC, so no need to fiddle with a tolerance value. I tested the POSITION values of a sprite travelling down the screen, and the values are in the 1-256 range. The bomb will effectively be off screen with value between 193-256, that should make plenty of room to catch it before it reappears at the top. orion1052003, on Tue Nov 8, 2011 10:24 PM, said: It seems kinda shaky when I run the program, for example if I hit the target the bomb will disappear. but if I miss it will continue on its journey up and down and wrapping down the screen again. If that's what's happening then you programmed it that way. You probably delete the bomb sprite when there's a collision. The routine (if any) for checking the bomb going off screen is obviously not working. orion1052003, on Tue Nov 8, 2011 10:24 PM, said: If I can get the "building printing" animation working, but it prints too slow, is there any way to speed things up? I've been looking at Graphicomp. The game seems to sort of work, but not smoothy or "classy". Printing numbers on the screen might help you trace a problem, but printing in the main loop is not a good idea. If you have to update a score, then do it after a hit. I don't know Graphicomp, but it I think it looked as if it pulled some graphics statements into data statements. Not sure if that really is going to help or the opposite. I don't seem to see any "building printing" animation. What is it supposed to be ? Lines 200-270 are the graphic codes for the buildings on the bottom off the screen. Perhps the buildings are 2 small in proportion to the plane. Line 385 where it says !DRAW BUILDINGS to line 440 draws them on screen in an initialization set-up phase. I tried lines 450 and 460 to make a "flippable" sequence of buildings, and when printed they came out blank, although I did not get a syntax error. I do not know if 450 and 460 are correct or acceptable to the TI. My thought was whenever the plane got to the right of the screen, the buildings on the bottom could flip between to frames, to give the illusion of passing over terrain. The plane constantly moves only right and wraps around like I think Atlantis by Imagic. Anyway, the static buildings look nice, but I thought I could add some realism. Not sure why it doesn't work when I put 450, 460 in. The space becomes blank. Lines 1050 to 1080 is where I try to implement the idea, in SUB BUILDN. I changed line 720 big time to try and implement your advice, if I interpreted it correctly. The game loop is from line 700-1000. Now the DOT does not show up, although the CALL SPRITE statement to place it on screen is still there. ??? I know I probably accidentally told it to do what is happening, but I can't find where. I REMmed out SUB BUILDN to try and make DOT run like it had before, when the buildings are normal "static" in the background. I never use double sized sprite pixels unless it's for something squarish like rectangular or frame stuff. I can understand the need for sprites to be big for attention, but I much more like the same resolution with sprites and background. I guess most have emulators (and real hardware) showing all the pixels at a certain magnification (I use 2x1 no filters all the time - also when I post screenshots). Only thing is - with no double size sprite pixels - coincidence checking is of course going to be about twice as difficult (for the program to catch). I would then only have buildings/skyline in the DISPLAY range (28 characters wide). Make a string which is a multiple of 28 (that would then be 28*2=56, 28*3=84, 112, 140, 168, 196, 224 or 252). Then use SEG$ to extract what is going to be displayed. Using 56, 112 or 224 is convenient because we can make bit masking. Let's take the width of 112 (4*28). You create an interesting skyline with 112 characters in one string. To control the flips though the 112 characters, we need a variable. Let's call it FLIP. Every time we need to flip, we can increase FLIP by one and secure it's range to be in 0-3. FLIP=(FLIP+1) AND 3 To display the skyline we could then have something like DISPLAY AT(24,1):SEG$(SKYLINE$,FLIP*28+1,28); My advice for logic is to only have one IF on a program line. If you have more than one IF then the second IF is only executed if the first is true. Something one might forget when changing the logic, testing etc. And it only becomes worse if one introduces ELSE. Only use ELSE for very simple program lines. I'm just saying it since this is the source of errors in pretty much all higher level programming languages (if you nest things up too much). When the game is finished and everything is working, and you want to optimize or make program code more compact and/or faster, then go ahead and try, but remember to test, test and test. 10

Happy Binary Day, everyone! It's 11-1-11. OR, 11-01-11 if you're a party pooper. 99ers are de best! James

Using Win99/4a on a mac. The mac is emulating windows, which is simulating the 4a. Ha. Using a virtual disk, have to check if it is nearly full or not. Oh, and happy 11-1-11. I wonder how the object file gets "embedded" into XB. I thought it was something simple, but perhaps it has to do with that complicated list of things you have to build in another Traver article, with "XBALBASE" I think it was called, and all that.

I got past that point, and assembled the source code it created to Dsk2.O. I meant to call it Dsk2.S, but I couldn't figure out how to rename it. Named the assembled object file DSK2.O2, but got an error. Can't figure out why. The Micropendium issue from 1991 has the first article and .dsk of GRAPHICOMP. I believe this is only the first version, not the final one I would need to use. I will try to upload the .dsk, article, and even the .mp3 of Barry Traver talking about graphicomp if it is small enough to fit here. http://pdf.textfiles.com/zines/MICROPEDIUM/mp9101.max.pdf It won't attach the 9101.dsk that goes with the magazine, at least not when I just tried.

Does anyone know how to use GRAPHICOMP by Barrry Traver? Do you you let his program look at your whole program listing, or do you just make a file of only graphic related parts? How do you get past the 4th screen? Here is a sample of some GRAPHICs I would like to speed up the drawing of in XB. I guess if it works, it makes a file and you CALL LINK to that file somehow.

Does anyone have videotapes or DVDs of TI-99/4A video they want to upload? Besides Bruce Maret's site, and several I've uploaded from Charles Good's DVDs, I don't know of any. I uploaded 2 by CRaig MIller. Are there any more Craig Miller videos? Does anyone know if he ever made one about NIght MIssion?

Can you do a CALL SOUND and a CALL COINC at the same time? Or does it actually do one and then the other next? I ask because I hear that CALL SOUND is the only command or SUB that can run while another statement is running. While maybe DATA does that too.

Lee, thanks for pointing that out. I think I forgot to add some statements. I made a program called JOYPROG. First, I was just trying to make a test that would show the joystick values. It ended being 4 dots for the directions, one of which will light up when you move in that direction. Also, it shows some values on screen of variables like X,Y,R, and C. Then, it became a test to try CALL LOCATE with JOYST. Then I figured to test COINC. I put a stationary dot on screen, you can move your dot, touch the stationary one, and it beeps a coincidence. I wanted to try subprograms on a game, and I couldn't get em to work. I thought, why not try these subprograms one at a time in this test program? Changed the name to JOYSUB. In line 193 I set the Meteor coordinates for off screen. In 195 I create the Sprite, off screen and stationary. In the comment I remind myself of where it should start on screen and how fast it should go in the subprogram. I think I should have put 1074 CALL LOCATE(#3,DR,DC) :: CALL MOTION(#3,20,-20) The meteor probably appears to move because it is repeatedly called inside the loop. But since it is stuck at the spot like you said, Sprite #1 has to be moved there by the joystick and it registers a coincidence. I just added line 1074. Now it moves across screen, but gets cut off and starts again. Probably this happens each time as the sub is called. I guess CALL LOCATE and some statements have to be dome outside of subprograms, due to the looping effect?

This is a Joystick tester program and a test to see if SUBPROGRAMS will work with it. The CALL COINC works, but the "meteor" will appear over and over in the loop. Which seems to mean you can't use subprograms to call adversaries for the game player.

How would you do an "enemy" controlled bullet? I was trying to make a space invader near the top of the screen go across from left to right and shoot down at the hero. The hero is on the ground below or jumping in the air at any given moment. This is what I got, doesn't work yet, might be incorrect. 320 A$="08040F1B3F2F280600000000000000002040E0B0F8E828C00000000000000000"!ALIEN 330 B$="0000001818000000"!ALIENS BULLET 1081 SUB ALIEN 1082 AR,AC=1 1083 CALL LOCATE(#4,AR,AC) :: CALL MOTION(#4,0,10)!ALIEN 1084 CALL LOCATE(#5,AR+10,AC) :: CALL MOTION(#5,20,0)!BULLET 1086 !ALL SOUND(XX,XX,XX)!FILL IN 1087 CALL POSITION(#4,AR,AC) 1097 CALL COINC(#4,#1,10,A) :: CALL COINC(#5,#1,10,B)!B=BULLET 1098 IF A OR B THEN CALL SOUND(XX,XX,XX) :: CALL DELSPRITE(#1,#5) 1099 SUBEND

A question on CALL COINC. Does it matter if CALL COINC is called from the MAIN or called from a SUBPROGRAM? Is it better to have it in both main and sub like I do now, as you mentioned about Line 661, or is it overkill/unnecessary? I thought the more you call it, the more likely to catch a coincidence, but perhaps only one CALL COINC per subprogram is necessary? If I call all those subprograms from the game loop, won't it slow the game loop action down considerably? Is there a way to CALL the Subprograms outside of the main game loop?

I will try this pseudocode/brainstorming/flowchart thing. What is the first thing you would need to do to make the man able to jump both left and right? Do you need to use the variable Face to accomplish this?

Since I am both not understanding and misunderstanding Subprograms, I thought I would run some tests to find out what passing a variable is and how it works. (In the program I've been writing the variables never pass, and I'm not even sure when they need to be passed or left alone) Probably another 10 tests to do after this, but here's something. In some of the looped RUNS of the subprogram testing program I only wrote down the first results, because the other results were expected, and I took screenshots of all 10 runs. Just lazy to write all that down. These tests may seem silly, or not even make sense, but it is just an attempt to understand.

Well, my thought for my first game was to finish it completely, then dish out a free game to the community as a surprise. I figure it putting it all on here would blow the surprise, even though the game is probably no big deal. It does make it easier to learn with the public forum, with trial and error and different input instead of trying to finish it in private. I put most of the code on the CALL COINC thread. Not sure how to do 3 things at once. It seems like the program can CALL JOYST, CALL DOT, and CALL enemies one at a time in a sequence, but it needs to be done simultaneously. When you have to wait for all the enemies to go by before you can move the joystick again, it's not working right. It seems to be like this CALL JOYST CALL DOT CALL ENEMIES REPEAT instead of CALL JOYST- CALL DOT - CALL ENEMIES , where you can move around, touch the dot, jump out of the way of an enemy all in "real time". When I call the subprograms, it seems to be just a stack of tasks that are completed in order, so I have to do all of them before I can start over, preventing the program from doing several things at once. I don't know if the structure is call all subprograms in the game loop and make the game loop too long and slow, or make a short fast game loop and not be able to call the subprograms. Catch-22.

While running around the screen after a dot, one enemy would always be on screen pestering you. After a short time, a new enemy would appear. A series of enemies would just repeat over and over, one enemy at a time. Kind of like the Spider on Centipede keeps popping up again every few minutes after you killed it. Except there would be a gnat, and then an earwig, followed by another bug in this games' logic. Not actually bugs, just any "enemies" for the player. The program doesn't work, and as you can tell this is my first game. Currently, you can move left or right and wrap around, do a buggy jump, and get some coincidences out of a meteor that disappears when it hits the ground. (Intended) The collision detection is a mess, and I'm not sure which of the several CALL COINCs are working and which ones aren't. I think the ones in the SUBPROGRAMS aren't. It seems like nothing I put in a subprogram works, and it gets confusing when it comes to what variables and values need to be passed from SUB to MAIN and what ones don't need to be passed. Not understanding Subprograms so far.

The movement seems a little better than before. The problem I notice is when you run to the left, and are near the right edge or another spot more in the left of center screen,... when you press the button, the man pops into a much further spot to the left suddenly before jumping. The jump still only goes to the right, not sure how to make it jump left when facing left, and keep jumping right like it currently does when facing right.

When coming down from a jump, he passes right over the meteor without a beep or a flash.

Sometimes, what is your private e-mail? At 23 seconds in this video, there is a dot chasing routine. I have a subprogram to place a random dot on screen. Like the car, the man would touch the dot, and it would disappear only to present itself again somewhere else on screen. The Man would have to touch the dot a certain number of times, say 25. How could this subprogram be called, and simultaneously have another subprogram of an "enemy" running at the same time? I thought the pesky enemies would make it harder for the man to get the dot.

Hmm. Does this solve the negative non integer number, and out of range error? Or merely "patch" it?

Awesome!! Is this just Extended Basic on a regular TI or normal TI emulator? James

My friend also has a question about using call locate with joyst. CALL LOCATE(#1,(DR AND 255)+1,(DC AND 255)+1) I am not sure that I understand what you are trying to do here. (DR AND 255) and (DC AND 255) will return -1 if DR=255 or DC=255 thus only acting if either is 255 and then it changes the statement to be CALL LOCATE(#1,-1+1,-1+1) making either parameter zero which will cause an error. Since DR never changes I would rewrite as CALL LOCATE(#1,DR,(DC AND 255)+2)

Thanks, RXB.
