[Exult-general] Rendering Question

[Bryan M. <mur...@ya...>]

Hey Guys,

I've got a hopefully simple question.  I'm working on a small little
mod to Exult that will display the health of my characters on the
screen.  For example, I want the lower left hand corner to have
something like this:

/---------------
|
|
| Avatar:15/30  Iolo:22/35 etc. etc.
\---------------

To see how to do this, I've added a line of code to exult.cc to print
some text on the main screen as I play the game.  This all works fine,
except that when I move, the text streaks across the screen leaving a
trail in the opposite direction from which I'm moving until I stop.

The line of code I added was as follows:

        if (ticks > last_repaint + 50 || gwin->was_painted())
        // This avoids jumpy walking:
        {
        	//BPM
	        gwin->paint_text(1, "This is a test", 0, 0);
        	//!BPM

        	gwin->paint_dirty();
        	last_repaint = ticks;

Now, my guess is that gwin->paint_dirty() only redraws the portions of
the screen that have changed, and gwin->paint_text() is not marking
that portion of the screen as dirty.

Is this correct?  If it is, how do I go about marking that portion as
dirty?  Is gwin->paint_text() the proper way I should be doing this?  

Thanks for any hints!
Bryan
