So, when I have an application, that uses a background image (which is the origincal background for my question), the appropriate way to "redraw" a text would be:
- calculate the surface of a text one wants to draw - store this specific piece of the old surface somewhere - draw the text now, when redrawing the text: - blit the old surface over the text surface - repeat the above 3 steps for the new text Or is it done in another way? I'm not that familiar with SDL programming, maybe I'm just doing it wrong.
