Hi Rinne and company!

Can I make an Layout to use it for Main Menu?
For example this:

Can this not be used as boot.3dsx?

?

Yeah for sure.

Well, you know how the homebrew launcher is a .3dsx put at the root of the sd card and is called boot.3dsx?
Could I make a homebrew with this, and have it be the boot.3dsx instead of the homebrew launcher?

So you asked for the wrong thing, you said "Can this not be used as boot.3dsx?" xD.
Anyway, yes, it's completely possible but you have to do some difference on exiting function. (You can see Sunshell boot.3dsx "patch" for home-menu return here: https://github.com/Rinnegatamante/Sunshell/blob/master/LUA/sun_index.lua#L377-L381

Great work. Don't stress about the new *haxes breaking everything, people can still use older *haxes if they want.
I do have a question though, how would I make it so if color of pixel tapped = 255,255,255 then do this?

 

[Rinnegatamante]

You can use the getPixel function to get the color (It can assume an image or a screen).

Thanks. Then I would do:

if getpixel = 255,255,254 then
-- do something

Right?
EDIT: It doesn't have to be color based. I should rephrase my original question. How can I make it so that when I touch a certain part of the screen it does a certain thing?

Just use touchscreen feature. ( https://github.com/Rinnegatamante/Sunshell/blob/master/LUA/sun_index.lua#L197-L203 )

Ohhhh. Oh. Ohhhh. Well, thanks!

Maybe it's a stupid question but... can be used the SDL2 Lua binding with the Lua Player?

What do you mean?
SDL2 is a C library and it hasn't been ported to 3DS yet.

I used the listDirectory function like so:

filebrowser_arc_dir = System.listDirectory(System.currentDirectory())

But attempting to print filebrowser_arc_dir[1] throws an error saying that it's a table when it was expecting a string. Does listDirectory create tables inside tables?

Yes, you should do something like filebrowser_arc_dir[1].name to get the name

Okay, thanks. Are there any other values that are stored in the subtables, like modified date or something? And does the table's index start at 0 or 1?

 

[HexZyle]

Are the strings returned by the listDirectory function one byte per character, or are they something like UTF8? Because I just attempted a list directory, and it printed all the filenames, but with all the alphanumeric characters missing, only the underscores and periods printed out (my custom print function only detects alphanumeric characters and a couple symbols)

EDIT: Nevermind, I forgot my string printing system will only print capital letters. I need to auto-uppercase anything that is being read by my string printing system as a failsafe.

Hi, I'm new to lua and I am trying to open a file that was created using tiled. Here is my index.lua:

testmap = io.open("/test.lua", FREAD)

consle = Console.new(TOP_SCREEN)

text = io.read(testmap,0,1139)
io.close(testmap)

while true do
  Screen.refresh()
  Screen.clear(TOP_SCREEN)
  Console.append(consle, text)
  Console.show(consle)
  Screen.flip()
  Screen.waitVblankStart()
  Console.clear(consle)
  pad = Controls.read()
  if (Controls.check(pad,KEY_A)) then
    System.exit()
  end
end

It gives me no errors, and it works fine in Citra, but when I try it on my O3DS w/ ninjhax, it just shows a black screen. Do you know what I am doing wrong?

Where you placed your scripts?

 

[tesnos6921]

Where you placed your scripts?

I placed index.lua & test.lua in the folder where the .3dsx is.

 

[ihaveahax]

I placed index.lua & test.lua in the folder where the .3dsx is.

you should change

testmap = io.open("/test.lua", FREAD)

to

testmap = io.open(System.currentDirectory().."/test.lua", FREAD)
