SDL_ttf speed question

SDL Development

How fast is SDL_ttf? I was going through writing a HUD for my game, and
to display various information, can I just sprintf() the info into a
char array and use SDL_ttf to render that char array every loop or
should I take the time and cache surfaces that haven’t changed?

Hi,

if you look for dynamic strings, SDL_ttf is not the way to go, because it
creates a Surface for each invoke you do. Try a lib like BFont. To use ttf’s
for it, you can check out my utility at:

It uses SDL_ttf to create the BFont compatible font-images.

Good luck!

Yes and if you program in C++ use BFont++! :wink:
