Quadratic Conversions

Tue, 08 Dec 2009 00:25:02 +0000

I am trying to make an application that will convert a standard quadratic function to one that's written in vertex form. ax²+bx+c into a(x-d)²+E. Currently it works but the problem is that it shows the outputed formula on several different lines. Could someone show me how to make it appear as one nice uniform line?

 :Prompt A :Prompt B :Prompt C :(-(B/(2A)))=>D :(A(D)^^2^^+B(D)+C)=>E :ClrHome :Disp A,"(X-",D,")=",E

If anyone wants to learn c++

Mon, 07 Dec 2009 10:18:25 +0000

For all of you who want to learn c++, I found a really good website. The site uses many different examples and there's a little quiz at the end of each section. Hope this helps you guys out. Reply if youre interested in c++ I want to work on a little project.

recovering the contents of a list from within a program.

Sun, 06 Dec 2009 22:39:48 +0000

I have a list. It has contents. On the home screen when I display the list I must press good old 105 to get the contents. How do I do that from within a program?

Running a set of equations.

Sun, 06 Dec 2009 20:09:26 +0000

This is another basic question (heh), but in order to save space, is there any way to write

 If(T/6=1/6 or 1+1/6 or 2+1/6 or 3+1/6 or 4+1/6 or 5+1/6

as just

 If(T/6=X+1/6

Where X is the values 0-5

Matrix and List

Sun, 06 Dec 2009 15:18:21 +0000

Hi,

I'm programming a game on my TI-84 Plus, but that's the same TI-Basic I think… So, I need to feed the chars of a matrix in a list like that:
Matrix:
111
101
010
1X1

List:
11010101111

The coordinate X is the players position, and the numbers around X (like shown above) should now be read into a list.
I have no idea how to do this job. Could somebody send me a code snippet? Please send me only the short snippet, because I don't have much time because this program should be finished until tomorrow.

Thank you in anticipation!

Greetings LM358

P.S: it seems that when I want to access a matrix I enter coordinates like this: [A](y,x) that's strange,…

Grabbing an object from a list

Sun, 06 Dec 2009 06:16:59 +0000

I am working on what is essentially my first game (beyond a rather snazzy Rock Paper Scissors), but as a novice programmer, I've just begun to discover the wonders of lists. I've made it so that the game makes a rather large list (36 units, either one or zero), but I now need to check which sum is present there. How would I, say, grab the value of the 27th position or (any other arbitrary position) on my list?

E.G {1, 0, 1, 0, 0, 0, 1, 0} -How could I get the value of the 3rd entry

Prime number generator, have a better one?

Sat, 05 Dec 2009 04:10:01 +0000

Heres one that I had a while back and just recently optimized, there's no hidden algorithms for finding if the number is prime, just repeated division.

 ClrHome For(A,1,1000,2 For(B,3,A-1,2 If fPart(A/B)=0 A->B End If B=A Disp A End

Just out of curiosity, can anyone make any improvements or is there just a much better way?

Insert Number into a List

Is there a way to insert a number into a list?
Thanks!

How can I remove the . after my integers when using int(?

Wed, 02 Dec 2009 02:30:02 +0000

When you use the int( function, it truncates every thing behind the decimal and just leaves the dot there.

Example:

int(5.84
5.

This is really annoying and I am wondering if anybody knows a fix..

Help with graph movement?

Tue, 01 Dec 2009 03:16:16 +0000

(general movement)

 :Zstandard :104→Xmax :72→Ymax :Zinteger :1→A :1→B :Repeat K=21 :getKey→K :line(A,B,A,B,not(K :min(94,max(0,A+sum(Δlist(K={24,26→A :min(62,max(0,B+sum(Δlist(K={34,25→B :End

(collision detection)

 :sum(Δlist(K={25,34 :A+Ansnot(pxl-Test(A+Ans,B→A

my current code

 :Zstandard :104→Xmax :72→Ymax :Zinteger :Horizontal 0 :Horizontal 62 :Vertical 0 :Vertical 94 :47→A :31→B :Repeat K=45 :getKey→K :line(A,B,A,B,not(K :sum(Δlist(K={24,26 :A+Ansnot(pxl-Test(A+Ans,B→A :sum(Δlist(K={34,25 :B+Ansnot(pxl-Test(A,B+Ans→B :End

When going right, my movement piece gets stuck about halfway between the starting point and the right wall.
When going up, my movement piece goes straight through the wall.
The collision detection works for both moving left and moving down.

What did I do wrong here? I don't get it..

Switched output

Sun, 29 Nov 2009 18:50:43 +0000

im writing another encryption algorithm, and it involves expanding the key.

to make the decryption keys, the encryption keys are made first, and then edited
on the computer, i labeled the keys 0-51, rather than 1-52,so every index is 1 less than the indexes shown below

 s49* s50# s51# s52* s47 s48 s43* s45# s44# s46* s41 s42 s37* s39# s38# s39* s35 s36 s31* s33# s32# s34* s29 s30 s25* s27# s26# s28* s23 s24 s19* s21# s20# s22* s17 s18 s13* s15# s14# s16* s11 s12 s7* s9# s8# s10* s5 s6 s1* s2# s3# s4* sXX* = multiplicative inverse of sXX modulus ((2^16)+1) sXX# = additive inverse of sXX modulus (2^16)

 for x in range(8): key += [invmod(temp[48-6*x]), two_comp(temp[50-6*x]), # i know these 2 are switched, but for some reason,  two_comp(temp[49-6*x]), # they give the right outputs for the others invmod(temp[51-6*x]), temp[46-6*x], temp[47-6*x] ] key += [invmod(temp[0]),two_comp(temp[1]),two_comp(temp[2]),invmod(temp[3])] # invmod is multiplicative inverse # two_comp is additive inverse

This is what im getting:

REPEATEDLY RUNNING PROGRAMS

Sun, 29 Nov 2009 16:52:13 +0000

When The list comes over from the other program the variables in REDUE are initialized as follows:

ClrList ⌊JONL1
SetUpEditor ⌊JONL1
ClrList ⌊JONL5
SetUpEditor ⌊JONL5
ClrList ⌊JONL4
SetUpEditor ⌊JONL4
JONL1 IS ERRORS, JONL5 IS TIME GREATER THAN 3 SECONDS AND JONL4 IS INDIVIDUAL REACTION TIMES.

Well when I use this at each recall of REDUE the list does not decrease in size but keeps the same values. What I think is needed is a new initialization routine for subsequent passes of REDUE. I unfortunately do not know how to do this. I have been at this for about three weeks now and had no idea what was going so that I could explain it to, until now.

Help with filling my matrices correctly?

 How can I make sure that 10 ones will show up? Occasionally they will overlap each other because of the randomness, which I can't have.
 (PS. This is my first game. I've been following tutorials and looking at the source of other games for examples, but if you see something else that should be changed beside the solution to my problem, please point it out. Thanks.) 
				 	


Coding TIBasic with a Normal Text Editor
Fri, 27 Nov 2009 20:30:08 +0000

						 Hi All
 Im new Here.
 Im Coding TIBasic since 2 Years. Now i want to code on the PC. I have got an Emulator -> VTI and i have Notepad++ but i cant send the programm files to the VTI because they haven't got the right format. if i look at files that i have made with the TI89 Titanium and transfered to the PC, they have got a Header line and a footer line with some binary data.
 But i cannot copy this data and i cannot write the data with the keyboard.
 I hope somebody can explain me what to do to get it working.

Transferring Asm Programs
Thu, 26 Nov 2009 03:35:47 +0000

Mandelbrot set
Wed, 25 Nov 2009 04:57:32 +0000

						 Hello, I am trying to make a program to plot the Mandelbrot set fractal, but it doesn't look just right and I keep using up all my memory when I have about 22000 bits RAM free.
 Here's what I have for the program now:
   :0→Z:0→F :0→N:0→C :-1→Xmin:1→Xmax :-1→Ymin:1→Ymax :Shade(1X-5,1X+5) :Lbl 1 :0→θ :rand→N:rand→C :(0+0i)→Z :Repeat abs(Z)≥2 or θ=10 :Z²+(N+Ci)→F :(F²+2F→Z :1+θ→θ :End :If abs(Z)≥2 :Then :Pt-Off (N,C) :Goto 2 :Else :Lbl 2 :0→θ :-rand→N:rand→C :(0+0i)→Z :Repeat abs(Z)≥2 or θ=10 :Z²+(N+Ci)→F :(F²+2F→Z :1+θ→θ :End :If abs(Z)≥2 :Then :Pt-Off (N,C) :Goto 3 :Else :Lbl 3 :0→θ :rand→N:-rand→C :(0+0i)→Z :Repeat abs(Z)≥2 or θ=10 :Z²+(N+Ci)→F :(F²+2F→Z :1+θ→θ :End :If abs(Z)≥2 :Then :Pt-Off (N,C) :Goto 4 :Else :Lbl 4 :0→θ :-rand→N:-rand→C :(0+0i)→Z :Repeat abs(Z)≥2 or θ=10 :Z²+(N+Ci)→F :(F²+2F→Z :1+θ→θ :End :If abs(Z)≥2 :Then :Pt-Off (N,C) :Goto 1 :Else :Goto 1 :End 
 
 I used the formula z=z²+c equation for the Mandelbrot set.
 When my calculator has the Memory error I go in and remove the Shade( command so it will continue on with the picture instead of filling it back in.
 Theta is used to limit the number of iterations that each point undergoes, stopping at 10 currently.
 The points outside the Mandelbrot's pool(or beetle) are erased, in theory leaving the shape of his pool in black.
 N is the x-coordinate of the point being tested, and C is the y-coordinate of the point. So you get z=z²+(N+Ci).
 rand command is only positive, so I used -rand to change the quadrant the points were in.
 If you have any way to save my memory while this program runs, or make it faster, or a better program altogether that would be greatly appreciated.

Basic Builder
Mon, 23 Nov 2009 22:03:18 +0000

Sleight has been here.
Tue, 17 Nov 2009 00:06:28 +0000

						 I got an 84+SE for my first year of high school (this year), and the first thing that I wanted to do with it was to learn what to do with this cool "prgm" button. I searched the web for a tutorial that explained stuff to someone who doesn't know the ABC's. There were plenty of those but the all stopped after D. Eventually I found this site, and here I am.My programing achievements include Ti-Sokoban (a homescreen sokoban game with a wicked title animation) , a Lights out game that uses inverted text and PRISMS and CUBES (a one point perspective 3D engine).
 Currently, I am working on rewriting parts of the Sokoban engine to use a string instead of the matrix for map data (thus making it faster on 83's) and contributing to the community 3D engine. 
				 	


Community 3D Engine
Mon, 16 Nov 2009 20:37:06 +0000

						 Three questions:
 Who is in with this project?
 What langauge are we going to use? (Basic or BBC Basic, I prefer the latter)
 What method? (Raycasting, the Sleight method)
 Once we get this sorted out I thought the next step to be to learn BBC Basic. Continued by Discussions arising from that and then the actaul coding!
 Let's get started!
 Many thanks for all your enthusiasm! This is a lifelong dream of me and with you backing me up I am quite sure I can finish it!

Storing to Strings
Sat, 14 Nov 2009 02:27:13 +0000

						 Just the other day, I decided to do a partial rewrite of my Sokoban game engine, so that it used a string for the map data instead of a matrix so that it would run faster on 83's. I made all the necessary changes, and it all works great except for one line:
   "5→sub(Str1,A,1 
 
 Evidently, you can't use sub( to store a value, like you can with other functions like dim(. Could someone please help me with this?
				 	


Calculating using Lists
Fri, 13 Nov 2009 21:50:52 +0000

						 I am trying to build this table in the Lists using a formula
 value of 8,350,000 is calculated by doing 16,700,000 / 2 using a (Half-year rule)
 value of 15,030,000 is calculated by doing 6,680,000 + 16,700,000 / 2
 CCA rate is calculated by taking the Beginning UCC and Multiplying it by the Rate of .20
 UCC can be calculated using a formula UCCn = C×(1 – d/2)×(1 – d)n-2 = 16,700,000×(1 – 0.2/2)×(1 – 0.2)^5-2
 I was only able to calculate only 1 value output it in the list using {(Ans(1))*(1-(.20/2))} ->L1 (The value of Ans is 16700000)

						 what's the best free antivirus program out there? ive used everything from AVG to Ad-Aware to Spybot S&D to a program that runs off my U3 flashdrive, but i keep getting viruses. and, the programs dont find the viruses in any case. ive used Hijackthis and Rootkit Buster but nothing turns up
 i know that i have a "malicious computer program" because system restore no longer works (there are restore points), windows defender thinks AVG isnt installed, and sometimes, minimized windows popup when i restore another window
 the last time i got a virus/bot/trojan/etc, the computer not only did that, but the computer wouldnt let me burn discs, the GUI was deleted or something and i was left with a 95/98 look, and i couldnt defrag or use diskcleanup. yet, the computer av couldnt detect anything
 anyone have anything better?

 I've been working on it for a very long time actually. I'm happy about it and it's fully operational. Includes:
 The basic blackjack (deal, hit, stand).
 The special actions (split, double down, surrender, blackjack, insurance).
 A save and load option (up to 3 files can be stored (however they can't be sent to another calculator but that shouldn't be a problem)).
 A textbox to show some of your actions and give information.
 I hope it's good enough to be worth trying… Tell me if you find any bugs or need to improve.

3D Rendering

 Using DelVar instead of ClrList allows you to save a tiny bit of memory (between 12 and 16 bytes) that ClrList doesn't delete, while keeping almost every aspect of the list clearing the same.
 
 ClrList is (more) useful (than DelVar) when you need to set its dimension to zero but you still want to check the size of the dimension. Example:
   If k=12 ClrList L1 ... If A and 2=dim(L1 Then Disp "Hello End 
 
 If you wold do the same but with DelVar instead of ClrList, you'll get an error at the second 'if'.
				 	


Getkey loop
Sun, 08 Nov 2009 21:51:14 +0000

						 I need to read the a keystroke from the user and stock it into the variable K, what's better (in terms of reaction time)?
   Repeat Ans GetKey→K End ... 
   Repeat Ans GetKey End Ans→K ... 
 Personally I think the second one… Or is it the same? 
				 	


growing string
Sun, 08 Nov 2009 18:50:19 +0000

						 can someone give me a general idea on how to write a program to output strings that grow in size?
 im trying to start from '' to go to 'A','B','C',…'c','d', and then to 'AA','AB','AC',.. 'zy','zz' until it hits 4 ascii chars. 
				 	


patents
Sat, 07 Nov 2009 18:18:53 +0000

						 if a program is patented, but the patent-group "released the patent under a royalty free license.", it means that anyone can write the program and then put the source code and any other stuff that has to do with it online right?
 and how does one use one of those open source licenses like GNU public license or coplyleft or something? do you just put "copyright" + year + name in the source code and include a copy of the license in the zip? 
				 	


Another logic problem
Sat, 07 Nov 2009 17:22:17 +0000

						 JONL4(I) is reaction time and JONL1(I) is indexed each time there is an error. So if things are good and the child has a reaction of one second "and" does not make a error in this loop pass then the child should see VERY FAST! on line six of the graph screen . If the child has been fast but made an error then the else command should display VERY FAST WITH ERROR. When I put this bad boy, inside a working program, It blows me completely of the program. I guess it is time for the professional programmers, that is you and this amateur programmer should wait in the wings for your response!
 prgmCLEAR6
 If ⌊JONL4(I)=1 and ⌊JONL1(I)≠I
 Then
 Text(6,1,"VERY FAST!
 Else
 Text(6,1,"VERY FAST WITH ERROR
 End 
				 	


8xp property changer
Thu, 05 Nov 2009 21:52:23 +0000

						 I have a lot of mario levels, and many of them have "rand(randHorizHAnsDegree" stuff in the names, and it gets annoying to change them every time. Also, my some of the files are in the ram, and i dont want to go changing the properties of each file to press the "archive" button
 is there any program that i can download to delete the random names of asm files and change their destination from ram to archive? 
				 	


SCROLLING HELP ANYONE
Thu, 05 Nov 2009 11:44:20 +0000

						 I would like to have a scrolling program to use on the home screen.
 My "musts" list is not very long.
 1) Since this is going to be used by children it must be user friendly when used in the program. The child must be able to control the scrolling, somehow. It would "be nice" if the child could use the function keys at the top of the 84 to do this. Like "STOP" and "GO" buttons or "SLOWER" and "FASTER" buttons.
 2) By whatever means it must not bifurcate text. We are having trouble with getting children to read let alone , deciphering a bifurcated word.
 My "wants" list is long and is based on my limited capabilities.
 1) I need to be able to load the application. If the available scrolling program does not have simple instructions, this old bird with limited memory, will need some hand holding☺
 2) It would be nice if I could work in TI connect, check it out there and then install it there in the application. Doing all that in the calculator will not be fun but I can manage that.

how to make a chess game?
Wed, 04 Nov 2009 00:01:03 +0000

						 I would like to make a chess game in basic, but I really don't know how to start it.. I was thinking create an 8x8 matrix for the dimension of the board. Also, store the coordinates of each piece in a list. But that would make 32 lists!! Is there a better way to do this? 
				 	


all correct→ wrong
Tue, 03 Nov 2009 22:13:05 +0000

						 is there any reason for a program in a loop to run correctly once and then be wrong the rest of the time?
