Homebrew [Release] {beta} sf2dlib - Simple and Fast 2D library (using the GPU)

A bit of a simple question but how do I install the libraries in devkitpro?

make && make install

Given that your enviroment is set up correctly

 

[tobiobito]

git clone https://github.com/xerpi/sf2dlib.git
cd sf2dlib/libsf2d
make
make install

So I did that with libsf2d and it said installed but when I try this with libsftd I get this:

c:\devkitPro\libsftd>make
sftd.c

You need to install portlibs first.

You need to install portlibs first.

C:\devkitPro\3ds_portlibs-master>make all
wget -O zlib-1.2.8.tar.gz "http://prdownloads.sourceforge.net/libpng/zlib-1.2.8.tar.gz"
/bin/sh: wget: command not found
make: *** [zlib-1.2.8.tar.gz] Error 127

If you are using cygwin, I don't think it comes with wget by default and you need to install the package yourself.

Thanks for the help btw. I am manually installing free type and I get this error:

There are precompiled portlibs on the "Releases" tab: https://github.com/xerpi/3ds_portlibs/releases

Hey,

I'm trying to compile my hb game on Linux. All the stuff at first goes fine (after two hours of removing small typos and fighting with the fact I dared to use more than one file for source), but then linker decides that it needs to go apeshit.

I installed sfil and sf2d libs, and yet I get multiple "undefined reference to 'sfil_load_PNG_file'", "undefined reference to `sf2d_draw_texture'" etc. errors.
Is this an error within the makefile (I just copied the one from 3DS ctrulib examples), or something more serious?

The problem here seems that your linker can't find the sf2d and sftd libraries. I suppose the fix should be between one of this option

1) Have you installed devkitpro in the default places? For linux it is usually /opt/devkitpro. If so, have you installed sf2d and sftd correctly? (a make && make install should do the job

2) Are you possibly using the makefile from the ctrulib's template? If so the error is explained. You should use the makefile from the example contained in the sf2d library (as the makefile from ctrulib doesn't link the sf2d library)

Yup, that was it! I used the one from sfil lib though, and now it compiles!
Oh well, now the worst part, testing.

Can someone point me towards loading a texture directly from a .png file instead of adding it as a binary?

You have to use libpng to get the pixelmap then pass that to sf2d_create_texture_mem_RGBA8. TGA is easier to load and you don't need a separate library, even easier you can also load RAW RGBA8 textures from a file.

https://github.com/xerpi/sfillib

That's what I used, and it's easier than @MasterFeizz 's method.

It is exactly the same method

 

[Spaqin]

Inside sure, but it boils down to one function sfil_load_PNG_file() that returns a pointer to sf2d_texture, so if he doesn't want to play with bare libpng and sf2d_create_texture_mem_RGBA8(), I think it's much simpler.

Hmm... I wonder using this is how many times faster than just regular framebuffer memcpy

Also, would it be possible to change the co-ordinate system? The renderer I wrote works from bottom-up, and not top-down, so {x=0,y=0} is the 0th physical pixel (bottom-left on the screen), and {x=0,y=1} is the first physical pixel (above the bottom-left pixel), {x=1,y=0} is the 240th pixel (to the right of the bottom-left pixel), and so on.

You simply have to modify the projection matrix, just switch the bottom and top values.

The only problem with that is that I have <0% knowledge with the GPU and 3D (my programs are mostly console-based because of this), so I don't know what to edit
If you could, could you please point me in the right direction?
