This is how I use SDL text

I saw a few people were having trouble with it. So until Cone3D writes one of his tutes heres my main file. You need SDL_ttf and you can get it from the library sectin at http://www.libsdl.org/. Thanks for the corrections Drizzt. #include "SDL.h" #include "SDL_ttf.h" SDL_Surface *screen; void DrawIMG(SDL_Surface *img, int x, int y) { SDL_Rect dest; dest.x = x; dest.y = y; SDL_BlitSurface(img, NULL, screen, &dest); } int main( int argc, char* argv[] ) { TTF_Font* font; //initialize systems if (SDL_Init(SDL_INIT_VIDEO) <0) { printf("Unable to init SDL: %s\n", SDL_GetError()); return 1; } //set our at exit function atexit ( SDL_Quit ); //create a window screen = SDL_SetVideoMode ( 640, 480, 16, SDL_FULLSCREEN); if (screen == NULL) { printf("Unable to set 640x480 video: %s\n", SDL_GetError()); return 1; } TTF_Init (); // Need the .ttf file in the same directory as // the .exe or give it the full path. font = TTF_OpenFont("Antqua.ttf", 20); TTF_SetFontStyle (font, TTF_STYLE_NORMAL); SDL_Color fg = {255,255,255,0}; SDL_Color bg = {255,0,255,0}; SDL_Surface *text1; SDL_Surface *text2; text1 = TTF_RenderText_Solid(font, "Hello World 1", fg); text2 = TTF_RenderText_Shaded(font, "Hello World 2", fg, bg); int done = 0; //declare event variable SDL_Event event ; //message pump while(done == 0) { DrawIMG(text1, 50, 100); DrawIMG(text2, 200, 200); //look for an event while ( SDL_PollEvent ( &event ) ) { //an event was found if ( event.type == SDL_KEYDOWN ) { if ( event.key.keysym.sym == SDLK_ESCAPE ) { done = 1; } } } SDL_Flip(screen); }//end of message pump //done TTF_CloseFont(font); // Don't forget to release the two text surfaces. // I forgot the name of the function return ( 0 ) ; } Edited by - Davaris on December 12, 2001 4:15:03 PM

There were two methods explained to me:

1. When using SDL_SetVideoMode() use the SDL_OPENGLBLIT flag with the others used for OpenGL. (Exactly how you render the text, I don''t know.)

2. Use the SDL_Surface obtained from TTF_RenderText_*() to create an OpenGL texture and putting that texture onto a quad on the screen. (This, I haven''t been able to get working either)

That''s something to think about.
