SDL_ttf Problems

SDL Development
1

Hi there,

I am reasonbly new to programming and SDL, and for my game I need to display
text on screen so I decided to use the SDL_ttf library to try make it
easier.

I’ve been trying to write a function for it, but since the sdl_ttf
documentation is scant, I’m not having a great time. Here is the function:

int DrawTTF(TTF_Font *font, int x, int y, char *disptext)
{
SDL_Surface *text, *temp;
SDL_Color white = { 0xFF, 0xFF, 0xFF, 0 };

font = TTF_OpenFont("Impact",12);
TTF_SetFontStyle(font, TTF_STYLE_NORMAL);
text = TTF_RenderText_Solid(font,disptext,white);

return(0);

}

What I want to do is pass in a x,y coordinate of where to put the text, and
also the text to pass in:
DrawTTF(font,300,300,“Hello! World”);

Unfortunatly, I am having no luck and was wondering if anyone knew a better
way to do it. The font face and size will be hard coded, so I dont’ care
about passing that stuff in, just a position on screen and a message.

Thanks for any help

Have you looked at showfont.c?

rect.x = x;
rect.y = y;
rect.w = text.w;
rect.h = text.h;
// Optionally: SDL_SetClipRect(screen_surface, &rect);
SDL_Blit(text, 0, screen_surface, &rect);
SDL_UpdateRect(screen_surface, 0, 0, 0, 0); // sloppy but simple

return(0);

}

Cheers,

Hey,

Thanks for your suggestions guys, but I got SFont working instead.

You may be mixing up Debug and Release DLLs and LIBs. If you compile in Debug mode, it won’t link properly to Release LIBs, and vice versa.

The simplest solution is to just build SDL_ttf from source. Make sure the project settings match those of your game. Or just add the SDL_ttf source files directly into your Code::Blocks project.

If you post your compiler/linker output, we might be able to give a more detailed/precise answer.
