Re: [Super-tux-devel] LevelEditor Progress...

 Anyway, it was working, couldn't we just port it again?

 AFAIK, you just need to create another surface, blit the surface you want =
to=20
blit into the screen into this one, apply alpha to the temp surf and then=20
just blit the temp surf into the screen. It is nothing from another world :)
 I have made the current code, and I dunno why it isn't working...

 In case it is too slow, we can allways get rid of it...

 And this code that can be found at draw_bg, draw_part or draw_stretched:
  if(alpha !=3D 255)
    SDL_SetAlpha(sdl_surface ,SDL_SRCALPHA,alpha);
will make the surface to have that alpha forever. This code should be remov=
