Hacking [RELEASE] Lua Player Plus Vita (lpp-vita) - Lua interpreter for PSVITA

[Rinnegatamante]

Description:
Lua Player Plus is a multiplatform LUA interpreter currently available on PSP (lpp-c++ / lpp-plugin), 3DS (lpp-3ds) and PSVITA (lpp-vita).
At current stage, it's good to make 2D games and apps but final goal is to provide a complete set of tools to make any kind of projects and make them easily portable towards consoles (lpp-3ds and lpp-vita for example both use a similar code syntax).

Features:
- GPU rendering support.
- Sound system support with native support to MP3, OGG, MIDI, WAV audiofiles.
- FTP server for fast scripts debug.
- Controls and touch/retrotouch support.
- Alpha blending support.
- Native support to BMP, PNG and JPG images.
- Native support to TTF fonts.
- Possibility to build standalone homebrews in vpk format.
- I/O functions support.
- Arithmetical functions support (mathlib).
- Minor functions support (Like battery ones).

In the RAR file you'll find the interpreter documentation, some programming samples and a builder (currently only for Windows) able to generate a vpk package from your code.

Credits:
- vitasdk and HENkaku devs to make this possible.
- @xerpi for vita2dlib and ftpVita srcs and for his awesome help on Skype .
- @gnmmarechal for testing the interpreter.
- @Misledz for the lpp-vita logo.
- EasyRPG Team for the audio decoder used in Sound module.

Fantastic work! I have very little experience programming but I'm excited to see if I can make a couple time-saving scripts with this.

 

[memomo]

awesome work, I'm really happy to see you here
I really enjoy your amazing homebrews for 3DS and I hope to see some excited homebrews for the vita
maybe a theme manager

 

[naughtyotsel]

so does this work for henkaku?

 

[Rinnegatamante]

Yes, lpp-builder will produce standalone vpk homebrews compatible with HENkaku.

 

[naughtyotsel]

i tried it but it didnt produce a vpk file

Have you followed the Readme? Is your system a 64 Bit one?

 

[naughtyotsel]

no i have a 32 bit one, so i cant use it?

 

[Rinnegatamante]

Quite sure vitasdk tools are built for 64 bit machines. Launch build.bat from a cmd instance and see what error do you get. (And from what executable)

With this, we can homebrew for ps vita ? Or ps vita don't need interpreter for start other lua homebrew ?

lpp-vita can be used to build Lua homebrews. I don't know what do you mean by "can homebrew" but anyway, vitasdk officially supports only C/C++.

Sorry, because on psp we can homebrew with LUA, and i know only C# and lua x)

I've done everything according to the readme file but when I execute build.exe (and after I insert the app name and title id) it suddenly closes and generates only a param.sfo file... isn't it supposed to generate a .vpk?

Little correction: it's build.bat not exe. Anyway, try to execute the batch script using a cmd instance and report me what you get as output. Probably some executable failed.

Seems I'm missing something...
And yeah, sorry for the little mistake. I was looking at vita-mksfoex.exe..

(I don't need to translate this, I suppose )

I've updated the release package, please re-download it and let me know if it fixed the problem.

 

[Bishibazu]

Ok,


I've updated the release package, please re-download it and let me know if it fixed the problem.

Yep, it works now! Thank you!

Now I just have to look for errors in my .lua file

EDIT 2:

Nevermind, rebuilt the database and the app is gone now.

 

[Jackall4BDN]

is there any relation or chance that we could see a port of Löve-Engine based on this at some point?
I am suddenly aching for some Not Tetris or Mari0

 

[Sancus]

When I compile to a vpk will the files in build be included?
example:
If I have arial.ttf next to index.lua
could I use
my_font = Font.load("arial.ttf")

Edit:

I have just found out that it is available in
app0:/NAMEOFTHEFILE

I'm not a Love fan so no, i'm not going to work on a port of such framework.
