: Someone should write a more thorough tutorial! There's still lots of SDL stuff people could port. --[[User:Tantric|Tantric]] 15:34, 24 April 2009 (UTC)
:: As someone who just finished re-writing a great portion of SDL-Wii I think you're a great candidate! ;) Seriously though I would love to see a good tutorial or even just an API reference written. I am madly reading the main SDL tutorial in the hope of figuring out if I can attempt to port the Intellivision emulator jzInTV to the Wii, a programme that thankfully already uses SDL. My biggest problem, aside from never using SDL before, is emulation of the 12+ button keypad. Anyway bring on a good tutorial / reference it would certainly help me in my quest - if I ever really start it. [[User:Ensign R|Ensign R]] 02:07, 1 May 2009 (UTC)
== Image ==
I just managed SDL to work on my wii, and i've made a little program with controller input. I've made it so, that it will show a red background when i push on the right button. What i want is to show a photo when i press the right button. How can i do that? Do I need to include SDL_image? And what's the function i have to use?
Thanks, [[User:GabberNL|GabberNL]] 14:25, 28 April 2009 (UTC)
I used this function:
<source lang="cpp">
SDL_Surface *load_image( std::string filename )
//Temporary storage for the image that's loaded
SDL_Surface* loadedImage = NULL;
//The optimized image that will be used
SDL_Surface* optimizedImage = NULL;
//Load the image
loadedImage = SDL_LoadBMP( filename.c_str() );
//If nothing went wrong in loading the image
if( loadedImage != NULL )
//Create an optimized image
optimizedImage = SDL_DisplayFormat( loadedImage );
//Free the old image
SDL_FreeSurface( loadedImage );
//Return optimized image
return optimizedImage;
And applied the loaded image to a new surface with this function:
<source lang="cpp">
void apply_surface ( int x, int y, SDL_Surface* source, SDL_Surface* destination )
//Make a temporary rectangle to hold the offsets
SDL_Rect offset;
//Give the offsets tot the rectangle
offset.x = x;
offset.y = y;
//Blit the surface
SDL_BlitSurface( source, NULL, destination, &offset );
But when i try to compile it it sais it doesnt have the length of the image. Can somebody help me?
