Homebrew [Release] Lua Player Plus 3DS (lpp-3ds) - LUA interpreter for 3DS

[cere_ender]

If you're not a developer, what you have to do with lpp-3ds itself?

Because I'm a developer, but I use lua instead C because my 3ds development is very low, and LUA is more easier for me right now. (Well, I know C, but I don't dare to programming for 3DS). And as Ninjhax doesn't work in rxtools 2.6, the only way to use lpp-3ds I found is installing it as cia. But only some example code (fixed with System.currentDirectory()) work, and does not show the main menu (execute program, ftp server, etc.

CIA build of lpp-3ds load index.lua file from SD root. It doesn't have a menu itself cause it's tought to be used for stand-alone homebrews creation.

I see. For FTP connection you recommend FTPpony for upload the code? Thank you very much for your support

edit: IDK why, but Controls.check doesn't work properly. Only HOME button works, but when I try to exit or change the program, always stucks at "Closing program".

ftpBrony is the best FTP solution for 3DS right now.
Check examples for Controls using ( https://github.com/Rinnegatamante/lpp-3ds/blob/master/samples/graphics_and_controls.lua )

Also post your code if you want help, telling "Controls.check don't work" is a bit shameless

Hi, rinnegatamante! here's the script:

if System.currentDirectory() == "/" then
    System.currentDirectory("")
end

Controls.init();

while true do
    Screen.waitVblankStart()
    Screen.refresh()
    Screen.debugPrint(10,10,"Hola mundo",Color.new(255,255,0),TOP_SCREEN);
    if (Controls.check(Controls.read(),KEY_X)) then
        System.exit()
    end
    if (Controls.check(Controls.read(),KEY_HOME)) then
        System.showHomeMenu();
    end
    Screen.flip();
end

Also I tried with pad=Controls.read() on the loop and Controls.check(pad,KEY_...) but doesn't work

Edit: Ok, If I use Controls.check(Controls.read(),KEY_HOME) then System.exit() end it works, but if I use any other KEY, don't.

On latest release of lpp-3ds, Controls.init is deprecated. Anyway, you have to use it inside main loop.

Okay, I can use controls if I put Controls.init() on the loop. Otherwise, doesn't respond. Thank you.

Hello Rinnegatamante, what's the way to edit image size once it is loaded?

 

[Rinnegatamante]

Hello Rinnegatamante, what's the way to edit image size once it is loaded?

Currentl images can't be resized via software automatically through lpp-3ds but i'll surely add this feature later.
For now, if you need such a feature you have to write your own rescaler using drawPartialImage/drawPixel feature.

wow, I don't know how to use this feature. You're doing a great work with this Lua Player!

Is there an example for GPU rendering?

 

[Rinnegatamante]

Is there an example for GPU rendering?

Nope but is very simple to use GPU rendering cause the syntax is very similar to Screen module syntax.
You can check how does it works on Asteroids 3D repo ( https://github.com/Rinnegatamante/Asteroids-3D ) or RPG Maker 3DS repo ( https://github.com/Rinnegatamante/RPG-Maker-3DS/tree/master )

EDIT: https://github.com/Rinnegatamante/lpp-3ds/blob/master/samples/gpu.lua Here you are a little sample for GPU rendering.

I'm interested in using this, but I have a couple of questions.

• Do I just run make, build lpp-3ds and rename the .3dsx binary and I'm good to go?
• The included libctru in this repository is 5 months old. Should I replace it with a newer version before building?
• Are there any issues or disadvantages to using lpp-3ds instead of straight C and ctrulib?

You don't have to use devkitpro to use lpp-3ds just grab R2 from releases

For the issues/disadvantages you're quite limited obviously on what interpreter offer and LUA interpreter take a bit of resources to run (like 1 MB RAM) but for the rest, you'll have only advantages (like a fully working Sound module easy-to-use, FTP server working with only a command, etc...)

Oh, I didn't realize the download links were under "free works" on your site. Thanks. I'll mess with it a little.

A few weeks ago, I found this thread while browsing, and I wanted to try it out. Unfortunately, I had no way of installing homebrew on my 2DS, so I couldn't do it back then. Now that Smealum released Tubehax, I installed the homebrew channel and tried to run a sample program on my 2DS. Strangely the top screen just turns black und the bottom screen turns red, after that my 2DS just freezes. Do you have an idea why it isn't working for me?

Update boot.3dsx with the new one Smealum released few hours ago or downgrade to NH 2.0 boot.3dsx.

Thanks so much! Now it's working, but I just ran the sample program printing "Test" and it's flickering a lot... Is that normal?

Don't know if it is an issue related to newest haxs. On NH 1.1b i have no flickering issues.

I restarted it 2 times and now it suddenly works fine
