Title: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 15, 2012, 03:51:57 pm

Hello :)

Just wanted to show a little project I'm busy on.
As some of you know, I mainly develop on Linux. This means testing Nspire Lua programs is a bit harder.
Nspire_emu works fine, but there is no mouse support.
That is why I set out to create something to run Lua programs natively (meaning without emulation) on my computer.
I started 3 days ago, and here is the result:

Spoiler For screenshots:

I use the Löve Lua framework, since it was also event based and that made stuff a bit easier.

Stuff I still need to do:

Mouse cursor changing
D2Editor support (maybe too hard)
math.eval --> TI.Basic interpreter
Physics. Possible but very hard
~~Saving state of script~~ done

If I forgot something I will update the list.

I eat you when this is not for windows. I need this SO bad if I want to develop nspire lua programs (but I do not have an nspire xD)

@aeTIos
It's for all os's!
Hey, and you are a big part to blame, since you pointed me to the Love framework!
Guilty I say!

Hehe Löve ROCKS.
It makes stuff sooo much easier!

That might be pretty useful, you won't need a Nspire or the emulator to run Lua programs.

Yeah, true.
Also, with the debugger it becomes a useful programming tool :)

Can this be set to scale the speed to what a real nspire could do?

Ruler: the timer that most programs use to time stuff is the same.
And keyboard input is set to the same rate. So in theory, all programs should act quite the same.

aeTIos, done

This is wonderful, and undoubtedly more lightweight (for both size and speed) than the large TINCS bloat :)

Post by: Jim Bauwens on March 15, 2012, 04:48:27 pm

Thanks Lionel :)

Also, cubefield works:
(http://bwns.be/jim/cubefield.gif)

I did have to change a speed variable though. Cubefield detects PCspire as a CX, so it set a variable to make the whole program go faster.
This will probably also be a problem in TINCS, and isn't really fixable (well, cubefield's code needs to be changed).

Very nice! May be able to bring me back to Ubuntu for calc development! :D

Downloads soon?

This is definitely cross-platform, as this itself is also written in Lua! :D Windows, Linux, Mac OS X - you name it :)
(I'm assuming there will be binary distributions: https://love2d.org/wiki/Game_Distribution)

This is some amazing work! :D This will truly unlock the world of Lua for me, and possibly for countless others as well! :D

Post by: Jim Bauwens on March 16, 2012, 03:53:17 am

@cyanophycean314, I'll shouldn't take too long before a release, as it's already quite progressed.

@alberthrocks, thanks! And yes, I will distribute it in .love files :)

jim: Er, I should maybe mention that you have to include the löve program :)

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 16, 2012, 06:48:23 am

aeTIos, people just install it on their PC and it will work.
Most linux distributions even have it in their package manager.

Wow, this looks really nice Jim! =) The fact that it is cross platform is great too!

this is extremely useful ö nice.. really congratz on this one. but how can it be used under windows? since alberthrocks said it should be possible

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: aeTIos on March 16, 2012, 10:32:22 am

You have to download Löve and drag the .love file over the Löve executable.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Nick on March 16, 2012, 10:34:03 am

and where can we find the download of the project (not the love files) since i don't see any download...

Erm, Löve? http://www.love2d.org/
PCspire isnt out yet.

aeTIos, people just install it on their PC and it will work.
Most linux distributions even have it in their package manager.

According to the wiki (https://love2d.org/wiki/Game_Distribution), you can also bundle the Love binary and the love file into one executable. It acts like a SFX binary - that is, you can simply concatenate the two together. :)

Code: [Select]

cat /usr/bin/love game.love > game && chmod +x game
So rest assured, you won't have to install Love to use this! :)

EDIT: Also, I've noticed that the screenshot has no blinking cursor when editing the text box. I assume this will be fixed? (Or it could be a crappy screenshot :P)

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 16, 2012, 11:37:11 am

alberthrocks, that's a lua program. The widgets are lua based (part of EEPro core).
I haven't implemented blinking cursors there yet, and it has nothing to do with PCspire :P

I will see how I'll distribute it in the end, as this isn't hard at all.
Code isn't available yet, but will be soon :)

This will probably also be a problem in TINCS, and isn't really fixable (well, cubefield's code needs to be changed).

That's really strange, because in cubefield the cubes speed is based on timer.getMilliSecCounter()
So it works nice with TINCLS. Where did you get your version ?

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 16, 2012, 02:59:35 pm

ticalc.org IIRC.

On the top of your code you check if it's a CX, and change a speed variable if it is.
I noticed that you use getMilliSecCounter, and my implementation of it should do the same.
Maybe the timer runs a bit slower on calc.

Got to test this ^^

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 18, 2012, 06:45:12 am

Yup, that is correct.
Since Nspire lua is event based, scripts use the timer to trigger updates in a specified interval.
And the timer in PCspire works the same, so the script should seem to run at the same speed.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 18, 2012, 10:59:10 am

"al" represent a color, and in this case the color red, with a alpha bit so that it's invisible.
I replaced the white in his image with it to make it transparent .

How's the speed by the way? Is it dependent on the computer or will it run at the same speed on every computer? It would be nice if it was the latter, for those who wants to make animated screenshots.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on March 20, 2012, 12:10:47 pm

People can already check out the code on https://github.com/jimbauwens/PCspire.
However, it's not yet noob proof :P
But it will :)

Currently these things need to be fixed:
- Drawing arcs (draws a full circle now)
~~- When invalidating specific screen parts, it can skip a couple of pixels. Shouldn't be a problem for most programs, but it needs to be fixed anyway.~~
~~- Text offsets need to be improved~~
- Images need better alpha support

These things need to be added:
- Tool palette (menu system that hardly anybody uses :P)
- Cursor changing. This is more hard because love2d doesn't support this directly

Stuff that I might never implement because they are very hard:
- math.eval (requires CAS engine and TI-Basic interpreter)
- D2Editor (requires rtf interpreter)
- Physics (love2d has physics, but it would be too hard to make it compatible with the chipmunk one on the nspire)

Programs I tested that work fine:
- Updated version of Cubefield
- LogoMagic
- Klondike Lua
- Some programs that use the EEPro widgets (I forgot the names, or maybe I didn't name them yet :P)
- Color Tetris
- BlockBreaker Lua
- Bloxorz
- some other tiny stuff I made :P

Post by: Jim Bauwens on March 21, 2012, 08:11:25 am

Alright, fixed the text offset and the invalidating bug.

DiagramNZ works properly with one little change:
It replaces the Lua function named "type" with a number value, causing some Lua parts of love not to function properly.
So, I just replaced "type" with "Type" (in the DiagramNZ source) and it worked fine :)

Post by: DJ Omnimaga on April 17, 2012, 02:46:23 pm

Awesome Jim. And I assume JSpire is for those who wants to try games directly into their browser? I wonder if in the future, an user could just upload a TI-Nspire file in the emulator and emulate it that way? Even better: a script to allow the emu to read Omni archives zip files and play tns files from there. (providing they're in Lua)

How is screen resolution handled by the way? Some Lua games might not look very great at resolutions other than 320x240.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Adriweb on April 17, 2012, 02:49:43 pm

Yeah we plan to fully integrate it within TI-Planet when it's done, I guess Omni can do that too !
Also PCSpire handles weel all kind of resolutions so that won't be a problem

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: DJ Omnimaga on April 17, 2012, 02:55:24 pm

Yeah. I assume it would require heavy PHP work from Omni staff part and modifying the download pages, which, sadly, would require a lot of time, which they lack.

Btw I notice the kubefield file is a js file. Does it means the games are ran through a Lua->Javascript converter prior launch?

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Chockosta on April 17, 2012, 03:03:43 pm

It would be also a good idea to add a "menu" key, since a lot of lua programs need it...

Really, congrats!

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Chockosta on April 17, 2012, 03:08:21 pm

There's no keypad in PCspire/JSspire, it only reacts to mouse/keybord input. (I think)
But there's no "menu" key on a keyboard, so no way to get the menu.

I thought it would be nice to add a "menu" button in the top right corner.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: DJ Omnimaga on April 17, 2012, 03:09:23 pm

Oh ok, I thought you had a keypad showing up and on my side none did.

But no other key actually works for now anyway, even arrows and enter, so maybe controls are not implemented at all yet.

Title: Re: PCspire, run Nspire lua programs nativly on your pc
Post by: Jim Bauwens on April 17, 2012, 04:19:09 pm

There isn't any key input support here yet.
It's just a PoC, when it's done it will have much more stuff.

The screen resolution will be 212*318 default, with options to change it.
Kubefield is a js file, and indeed I converted it in the beginning. But the end user will not notice anything about it (They will not need to convert lua files).

Currently it's a bit hard to open TNS files (lua files are no problem). This is because of the encryption, legal issues, and other stuff. But I'll look into it.

Now, eventually I'm planning to merge WEBspire, PCspire, nCreator and some other stuff together to form openSpire. openSpire will be an open source TI-Nspire software clone with aim on as much compatibility. There will be a PC version and a web version (and possibly mobile).
I have the knowledge to make it, just need the time. But it's a serious plan.

Post by: Jim Bauwens on April 19, 2012, 05:29:39 am

Ah, I see :)

Here is an updated version:
http://bwns.be/jim/WEBspire/JSspire.html

Key inputs work now so you can play the game. However, there is sometimes a little graphical glitch. The cause of this is the HTML5 canvas tag that sometimes glitches when drawing off the screen. Looking into that to fix it.

Sorry I got it partially wrong. It just looked old because an old version I had had the player control as a square sprite whereas on the latest version it is an arrow sprite. I also forgot to account for later features such as Speed up every 1000 points and change it colour.

This is awesome !
Cubefield is much more fluid with JSspire than with TINCS...
Really, this is amazing.

This will be great when it will be possible to play Lua games trough our browser... No more need to have a TI-Nspire!

And I have an idea to add math.eval()... The open-source CAS giac (AKA Xcas) can be used with the TI-Nspire/TI-68k syntax. Moreover, it is possible to use it through a web browser. (Demo (in french) (http://www.xcasenligne.fr/giac_online/demoGiacPhp.php))
But this would require a lot of work...

Anyway, keep up the great work!

This just doesn't seem to be working in LOVE 0.8. I've tried a lot of stuff, using both the zipped and installer versions of LOVE, and I've dragged the folder of PCSpire (from the zip file) onto Lua to run it.

It shows up with a flashing alternating white and black screen, stops responding and crashes.

W8 this is still Linux only if I remember correctly? Then I've wasted my time using LOVE 0.7.2 and 0.8 trying to run it as it's still not working for me :(

The best result I can get is a flashing white and black window that's giving me epilepsy (jokes, no offence to anyone). The window is titled PCspire though.

~~EDIT: How can you run it from the commandline? It just runs normally like a normal exe.~~

Spoiler For Blather:

Well I ran from the command line like this "love pcspire" (that's what I named the folder). Exactly the same result.
