Gaming / Fortnite on a HP Prime!
April 02, 2018, 01:34:02 AM
I put Fortnite on the HP-Prime!
So I have been tasked with making vision work well and very smoothly in the off-season. I will be using the Open CV library and coding in Java, has anyone had experience with using Open CV?
So this is the place to share any tests or tricks you have learned while programming/ using the HP Prime!

So DJ was wondering about if the new firmware made any speed differences with the speed of displaying GROBs, I have updated to the firmware 107701 (if that is the right number xD) and here is the speeds (in milliseconds):

G1 is set to 320x240
G1 no zoom, no alpha blending: 3-12 (consistent mostly on 3 with some spikes)
G1 2x zoom, no alpha blending: 29-41 (we see a significant speed drop here but I didn't specify the exact cords on G1 on what to display, when I did that it went down to 29-35 which isn't that big of a drop though)
G1 no-zoom, 50% alpha blending: 17-26 (it jumped once to 40 but that was only once)
G1 2x zoom, 50% alpha blending: 49-53 (this is super high so don't use this combo unless you are not drawing to the screen frequently)
G1 4x zoom, no alpha blending: 29-37, I don't know why 2x and 4x are so similar but it is probably because it stops drawing pixels after the coords are more than 320,240 or less than 0,0.
G1 4x zoom, 50% alpha blending: 49-56 again with the zoom and alpha the render time is high but like the others it is about the same to 2x zoom for some reason.

There is one bug with BLIT however and that is when you try and use 12 arguments. I saw a post on hp museum that said something about it and @timwessman confermed that it was a problem with the amount of args and it is a known bug. So that means you can't do zoom with alpha blending <_<. but that only means that 2 tests cannot be complete...

I used this program to time them:

EXPORT LineTime()
BLIT_P(G0,G1,[other arguments]);

So I am opening this fourm kinda late in the race but we can still use it year round.

I am a programmer from team 5712, this is how we did at the Standish competition in Standish MI here

So I am making this topic to share ideas and offer help.

Calculator Talk / HP Prime Programming Help
January 24, 2016, 03:55:24 AM
This is a cross post from HP Museum:
QuoteI have a question about the LINE_P and TRIANGLE_P commands. Both of them have optional advanced syntax, the help hints that it can be used for 3D functions and the such!! I have a hard time understanding the help on it is could someone could show me and give an example, the help is very appreciated ;)
So basicly I think there is already built in 3D functions for LINE_P() and TRIANGLE_P() O.O *.* O.O
(3D MinePrime here I come!!!)
It would be nice if @timwessman shed some light on the topic ;)

This is my first question here but feel free to post your own troubles ;)
So I have had this idea for a while and I know it will work but I, as of now am not as equipped as I need to be to start and I need your help ;). First of all what language should I learn to be able to communicate to the calc, and where would I get a wireless receiver for my prime? and also how would I tell when a new post has been posted.

Later I think I can connect it to IRC!

I will be using the messaging system for communication between computer and calc.

I have seen similar things done with the messaging system on the prime but have never done anything like it so I need your help :P

SynText is a IDE for your HP Prime (I think) it is the first for the Prime :)
- None (started on the project less than an hour ago)

Planned features:
- Sick IDE with Syntax highlighting, color scheme, and touch responsive!!!
-  Awesome note editor
- Also it will be able to edit all of the current app's vars and functions inside the editor
Major progress tomorrow (hyped to get my Prime back ^.^)

Calculator Development / Programming Games in Ti-Basic
November 10, 2015, 09:17:41 PM
When I first started programming it was on a Ti-84+ in Basic. I have come a long way since but I was always looking for a (sudo) complete/understandable tutorial, if this sounds like you this is for you!
[spoiler=Step 1 making your first program]
1. Go to the home screen and press PRGM
2. Go to NEW and enter a name
3. You are now in the Ti-84+ IDE

4. From now on the key strokes are in the screen shot ;)

5. Time to run the program, can you guess what it will do?!
[spoiler=If you have figured it out open this!][/spoiler]
Now you are past the first step! I will add on to these quite often until there you are ready to take to the skys with your new found skilz ;)

This is the next step, here we talk about the while loop!
[spoiler=Step 2]
First of all lets create a program:

We will be making a loop that counts X from 0 to 10 and then displays some text:
The first step is to set X to equal 0 and to make our loop

Now we have to tell the loop when to run:
This just says WHILE X is less than 0 run this code!

The next step is to tel the loop what to execute:
This makes X's value go up by one every time the loop is run

Now we have to give visual feedback when the loop completes!
CHALLENGE: Do this by your self and see what you can come up with (it doesn't need to be exactly like mine)
[spoiler=Only open if you wish to spoil the CHALLENGE]

But wait the output is cut off O.O how can wee fix this?!
Look in the next step to find out really how simple it is[/spoiler]

All you need to do is separate it into two commands!

Now you may be asking how on earth do we get that ugly prgmLOOPS off of the homescreen, that is also very easy
[spoiler]Just add ClrHome to the first line in your program

Now you will get this:

Now for that pesky Done at the end:
[spoiler]All we do here is add a Pause at the end and that makes all line execution stop until the user presses enter

It should give you this:

Congrats you have finished part 2!!!!

Yesterday this happened to a school I attended 2 years ago, the car smashed right into my home room O.O. It is very humbling to think "I could have been in there." (it happened early in the morning so no students were there though)

Also read the comments, very morbid people O.O

Other / Speed Cubing
September 20, 2015, 04:36:52 PM
I recently have gotten into speedcubing (or solving Rubic's cubes really fast) I was wondering if any of you guys were fellow speedcubers. If so what is your method you use and what is your best time?

I use the Fridrich method and my time is 42 seconds and am currently learning all 57 OLL algs
One morning you woke up in a world of pixelation, you got out of bed and looked out the window and saw large gray blocks whizzing by your house so you went outside to see. As soon as you set foot out of your door there was a huge ruch of wind pushing you out of your house into the giant gray objects, your only choice was to jump...

The first one was easy you simply jumped over it but the second you had to dive under ever while the wind was fighting against you, then the third looming gray obstical came at you, there was no place to jump, slide, or die. Your ony choice was to drop kick it, with your eyes closed and you whole body at risk you landed it! You got faster now and things were turning weird colors of red, green, blue and then you noticed you were turning colors! What seemed to be the end you barely had tme to touch the ground bfore you had to jump, dive, or kick your way through an obtical.

Finially you got out gasping for the air that you hoped was there, and then you realized  the terrain was changing back to normal, slowly you could see the curves of the mountians, and you were actually human now not two stacked pixels but there was something wrong, something very wrong. you looked back at the mountians and you could make out jaged pixels, you looked back at your self and realized your shoes were more like triangles, then you realized "I am not out of this yet..."
I have no idea how to do it but I want to keep windows 7 when windows 10 comes out but still have windows 10 on my PC, so I would choose between win7 and 10 when my PC boots. How would I do that?
This is UtilPack and UtilComp (I will post a download tomorrow). UtilPack is a lib for the HP Prime! Right now it has three functions:
[spoiler=Functions]GETTIME(); returns the time in a list: {H,M,S}
GETDATE(); returns the date in a list: {Y,M,D}
RUNPROG(Prog); runs Prog (but has the same limitation as SIFS right now (it cannot run programs with arguments in the main function :())[/spoiler]

UtilComp will be a UtilPack compiler so when you release the program/ game to the public the user won't have to have UtilPack on their calc.
NOTE: if you have UtilPack on your calc and you are a developer you don't need to compile it because it uses the functions right out of UtilPack ;)
Hey look another project that won't get done :P. As you might know MinePrime development is paused until I find a way to display the world quickly or the "bug"/ constraint that appeared in the new firmware update is fixed/ removed. Because I don't have a major project now besides JarvAxe 5.0 (which will be complete someday) I decided to make a cousin to JarvAxe 5.0 coined S.I.F.S. or Super Intelligent Friend System (possible changes to the name in the future). S.I.F.S. (pronounced Sifs) will be a Shell if I can run progs in a prog, a program editor, a AI chat box, a notes editor, and random stuff to change settings about the calc.

As of now I am still in the middle of testing the possibility of some of these features and no real code has been written so ideas are much appreciated :)

Thanks for the help and support :)

NAGOJI 4x3 pronounced NA-GO-JE is a game for the HP Prime. You are a skillful ninja with super human powers to jump, dive, and smash through anything in your way! But there is one catch you must defeat the master of all pixels. He is taller and stronger than you, he throws obstacles at you and he is incredibly scary  >B) but you the  :ninja: shall only prevail if you got da skillz. The question is if you can make it past all ten levels and defeat the master of all pixels to free your self from his cruel rule.

This game also has the retro feel of the z80's lcd just to make it feel more awesome!

[spoiler]I am not responsible for any rage this game causes comparable to flappy bird, also in higher tier levels you make have seizures if so consult your doctor promptly and see if this is right for you[/spoiler]

EDIT:Here is the GIF

Sorry about the quality I need to tweak my OBS
Hello this is a 2D Minecraft game for the HP Prime. It is now in version 4.0 and has moved on to Applications. version 1.0 was a program and was mostly me experimenting with HP-PPL, 2.0 included block breaking and placing but was scrapped after technical problems and replaced with 3.0, 3.0 was just a menu system I developed so I am not even sure it is worthy of a version in itself, 4.0 is just as far along a 3.0 except it is moving along much quicker.

So that is the history of MinePrime but practice makes perfect so May the Fourth be with you :P

More technical outline of how world data will be stored and loaded and also collision:
Collision / Block durability:
what I do here is I use a GROB that is the same size as the world dimensions. If the pixel at your coordinates is black then it is free to move through, if it is anything else and you will not be able to go through it. And its color value is the block durability.

Storing worlds and world data:
This is where I really need Apps. With AFilesB() you can return and store individual bytes directly into the App files. So I can use this as a super compact and small list that makes up the world, they will then be formed into a matrix that will be used to store data while the game is executing. Then when the user quits it turns the matrix into a list and stores it into the App. If this is a acceptable way to do it it would be nice to have some feedback, especially from @timwessman.

Drawing the world/ terrain:
For this I am going to use a method I used in the last versions quite allot. I will make a GROB which will be one block larger on all sides, this will allow for smooth scrolling and also decrease lag if you are not moving much.

Player Movement:
This will be where 4.0 really shines, it will have movement like Zampy's Quest (for those that don't remember, it let you move one pixel at a time) not that it is super cool but it is something the other versions lacked. But unlike Zampy's Quest it will have impeccable collision because it uses pixels. Why Pixels are so great at collision is because they will only position at the integral part of the number (ex: PIXON_P(1.9999,1.9999,#FFFFFF) and PIXON_P(1,1,#FFFFFF) both make the pixel at (1,1) white).

I hope this wan't so confusing but I explained it all the best I could :)

Block list: OUTDATED!!!

Times all block ID's after 1-10 by 10 (so block 2(dirt) would be 20 and block 3(grass) would be 30 this gives me room to add block durability ;))
1-9 - Break animations
60-Oak Leaves
70-Tall Grass
90-Refined Stone

Hello, I am making a game that you all know called Minecraft on my Prime and I need help with sprites! Also the way I move in the world is by drawing blocks from values in a matrix so every time I move I have to redraw the entire screen and that takes time so I was wondering if there is any way to copy part of the screen and paste it at another part so I would just have to fill in one part, or even if there is a way to shift the screen over at all like the horizontal+ command in Axe?

Thanks for the help in advance ;)

This topic is mainly for my project JarvAXE 5.0 because I need help with my AI response system but this topic is open to anything to do with interactions that have some intelligence behind them like a chess CPU.

(I quote myself)
QuoteThe way he responds is when I press a key it records that key code in a buffer then when I press enter it adds those codes up into a buffer until it hits a space then it goes into the next spot and so on, after that    I use a for loop checking for values in the buffer that match with 130 which is "hello" and all the other responses. My only option is when I  finish a word I take that and compare it to the next word and it's meaning and then store those values into an appvar but the appvar would get very big very fast and I would have to have it in RAM because I will have to write to it :(. I could probably put the values into free ram but I will still have to open up alot of ram when I unarchive the appvar.
How could he learn?
Hello everyone I did not see a topic about regular glitches with your calc and specific Applications so I decided to add one :).

Anyways my question is about zStart. I put zStart on my calc and it didn't work :(. Do you need a OS lower than 2.55MP because that is what I have? And also is the latest version 1.3.013?

This is a AI system made in Ti-Basic I am working on an Axe version of this but it is not along enough to post.
