Hello, Thanks for your answers ! I have multiple remarks here :
1) I know that SDL2 should not be used "as is" in Pharo and I should use
OSWindow instead, that's why I won't use SDL2 directly anymore.
2) But for the moment OSWindow uses SDL2 anyway so for experimentation
purposes I will try to see what's wrong with my code.
The example you linked Nicolai is working indeed and this is more or less
what I did too. I included my code with this e-mail so maybe you can have a
better understanding (I am sorry but I didn't comment it :s). Note that for
it to work you need to add the SDL_image library and all its plugins (for
handling jpeg, png etc.) and add the following method to the image :
SDL_Renderer >> createTextureFromFile: file
<primitive: #primitiveNativeCall module: #NativeBoostPlugin error:
errorCode>
^ self
nbCall: #( SDL_Texture IMG_LoadTexture ( self , String file ) )
module: 'SDL_Image.dll'
You can launch the game by executing "MyGame new startGame"
On my computer (which is probably not the fastest I must admit) running it
with a fork slows the whole operating system.
3) Another problem I had lately : I tried to use Pharo with linux (ubuntu
14.04.2 LTS) and Pharo just can't find the SDL library.
I downloaded SDL source code and compiled it so i got the
libSDL2-2.0.so.0.2.1 exactly as in the SDL2 class >> findSDL2 method.
I tried to put it everywhere (in the "shared" and "bin" folder of Pharo and
even at the root. I tried in /usr/lib/, in /usr/lib32/, in
/usr/lib/x86_64-linux-gnu etc. and Pharo can never find it.
Could it be that I compiled it for 64bits (my ubuntu is 64 bits) and Pharo
does not support it so I should recompile it for 32 bits ?
Thanks you all !
