Re: [pygame] font alpha

Ah, well eventually I'll be overlaying different font layers over top of one another so maybe you're right in that my solution is still unsatisfactory.

haha...  I assumed you wanted something font letters with alpha - so
you had something that could be drawn over something other than a
solid color - but I guess you could always grab the background behind
where you want the text in a surface, blit the text over the piece of
the background you grabbed in the surface, then set alpha on the
background surface and blit that, and it would work for the effect you
want no matter the background.

Rendering the semi-transparent text with the appropriate background

newSurf.set_alpha(100)
screen.blit(newSurf, (0,100))

pygame.display.flip()

time.sleep(5)
