1. bk_color()in pixel graphics mode
Hello Everyone !
Just a little question : I'm coding a little game in graphics_mode 256 and I
need to display a lot of characters very quickly, but each with a
background color. I tried Putsxy, a great library, but it's too slow. I
tried also to do that with puts() but bk_color() in pixel graphic mode
affect the whole screen ! So I don't how to put a char with a
background color on the screen in pixel graphic mode without using putsxy.
Can you help me please ???
Ciao !
Gwen

Hello Gwenaël,
Look on the Archive or on the recent contributions page at RDS's
site. Or to get a lot of libraries to display fonts, just go to
the recent contributions page and in the search sle put Font,
I'm sure you're going to get a lot of different libraries.

Unfortunately, guys, putsxy is as fast as they get. If you need to
change just the *foreground* color, you could use rfont, that allows
you to change it 'on-the-fly'. In other words, it makes it possible to
write a whole lot of differently colored characters in one go, which
is much faster than printing individual characters. But I am sorry, it
did not seem important enough to me to provide 'on-the-fly' change of
the background as well...
Btw, 256 color modes, apart from mode 19, are often VERY SLOW anywhere
away from the first few lines. So if you can live with just 16 colors,
mode 18 would be much better choice. jiri

Thank you for your help !
I like very much Rfont, and I added back color changing on-the-fly
(unfortunately, It's still slow in mode 257).
I have an another problem : Neil is very fine concerning virtual screen, but
I don't know how to use Rfont with it ! So, how can I "simulate" an virtual
screen with Rfont in mode 257 ? I explain : When I move the whole text on
the screen, it flickers, and I would like to avoid that, but I don't know
how to do that without a virtual screen. Help me please !
Thanks in advance !
Gwen
