Temat: [C][SDL] obrót sprite o wektor

With SDL you have a few choices.

Rotate all your sprites in advance (pre-render all possible rotations) and render them like you would any other sprite. This approach is fast, but uses more memory and more sprites. As @Nick Wiggle pointed out, RotSprite is a great tool for generating sprite transoformations.

Use something like SDL_gfx to do real-time rotation/zooming. (Not recommended, very slow)

Use SDL in OpenGL mode and render your sprites to primitives, applying rotation to the primitives.

Option 3 is probably your best bet because you gain all of the advantages of using OpenGL. It's really up to you how to want to do it. It's also a possibility that you can load your sprites, perform all rotation calculations with SDL_gfx and then save the rotated versions to a SDL_Surface in memory.
