Homebrew Whats the best way to start programing homebrew on tubehax for a noob?

[Mr. Elementle]

I've been involved in some minor hacks and stuff before, mostly just graphics, but recently i've taken an interest in learning to program my own 3dsx homebrew, my programming knowledge is limited though.

Whats the best language to program in? I've seen a lot of people use C++ and C# but i keep seeing LUA being tossed around and whats the best way to compile for 3dsx files since i can't get visual studio to run.

EDIT: I should mention my first project i want to do isn't an original homebrew, it's a port of the ds homebrew IKUreader if it matters, i figured porting might be a bit easier to start with since i can study the already written code and see how it works, correct me if i'm horribly mistaken

If you start developing in LUA you don't have to set up any development environment and you don't have to compile anything in 3DSX cause lpp-3ds is just compiled.

I've tried using llp when i put my homebrew app in the 3ds folder then run it I just get a green pixel and no hello world text This is with ironhax 2.1

Your probably wrong with paths.

My homebrew name is llp in the llp folder i have helloworld.lua and a file called LLP.3dsx here is my code

while true do
Screen.waitVblankStart()
Screen.refresh()
Screen.debugPrint(400,240,"Hello World",Color.new(255,255,255),TOP_SCREEN)
Screen.flip()
end

File must be named index.lua, for the 4th time, have you at least read the OP of lpp-3ds thread? ... http://gbatemp.net/threads/release-lua-player-plus-3ds-lpp-3ds-lua-interpreter-for-3ds.384202/

Stop giving him the wrong information. He needs to learn first.

Thank you very much i didn't realize there was already a site for this

I recommend you learn C++ first before going to that website. There is no such thing as learning code specifically for one thing. You think the creators of those emulators went to that website and learned? NO! They learned C++ first and did it themselves. If you want to code like them then follow what I am saying. If you want to learn only specific things then you can go to that website, but if you want to learn how to do your own custom things then learn C++ first.

I tried finding it after about the eight page i gave up

How is that wrong information? I gave him a tutorial on how to set up the environment and if he want's a few crash courses in c if he want's legit lessons.

He will never code properly with that website. If he learns legit first then he can create something no one has created before. Learn C++ legit then look at the tutorials. Stop being stupid. He won't understand a thing if he starts there first. He will be really confused.

Your good at coding. Can you agree with me? He will be confused and won't understand a thing if he starts there.

I always that that meant original poster xD. So i got it to work but i get a error about out abound buffors

400 x 240 is the screen size for the top 3ds

my code :
while true do
Screen.waitVblankStart()
Screen.refresh()
Screen.debugPrint(240,400,"Hello World",Color.new(255,255,255),TOP_SCREEN)
Screen.flip()
end
Also, everytime i leave the program i have to reboot the netloader via the y button

void Screen.debugPrint(int x, int y, string text, u32 color, Image_id screen_id, [Eye_id] eye) - Write a string on screen or image.

Sample usage: Screen.debugPrint(0, 0, "Hello World", Color.new(255,255,255), TOP_SCREEN)

So is the while loop in lua equivalent to a void function in c

Nevermind, didn't work the way i thought it would i'll continue experimenting.

while loop in lua are the equivalent of while loop in C...

You had me thinking it was a void because you put.

void Screen.debugPrint(int x, int y, string text, u32 color, Image_id screen_id, [Eye_id] eye)

which i figured would go in the while loop then outside the while loop i would put

Screen.debugPrint(0, 0, "Hello World", Color.new(255,255,255), TOP_SCREEN)

to have it drawn

Ok, i'll restart from another point of view.
Do you know basic of C?

void is a type which means a generic variable substantially when used as a pointer and a null variable when used as a variable.
Functions in a documentation (like in header C/C++ files) are reported like this:

return_type name_of_function(type_of_argument name_argument);

so

void Screen.debugPrint(int x, int y, string text, u32 color, Image_id screen_id, [Eye_id] eye)

means that Screen.debugPrint doesn't return any kind of result.

Yaye i fixed it! Thank you for your help. I will definitely use Lua3DS for Osu3DS!
