Your error is there.

They should be SDL_Surface *, pointers…–
Best regards,

Seems pretty straight-forward, rootzoomSurface expects a pointer to a
surface, but you’re giving it a concrete surface.

Maybe “SDL_Surface* temp = visuals->SpriteBMP[0];” instead? (I’m just
guessing. Maybe it returns a pointer too?)
