Hi all, just wondering if anyone might be able to help me with a little
problem I'm having. I'm trying to use Exotica's
SURFACE_RECT_BLIT to fill in a region on the screen. In the docs it says to
use the command
c_func(SURFACE_RECT_BLIT, {Rectangler_Region, Color})
but I'm not sure what to fill in for the rectangler region part. I've tried
funcval=c_func(SURFACE_RECT_BLIT, { {20,20},{30,20},{20,30},{30,30} , 256})
and
funcval=c_func(SURFACE_RECT_BLIT, { {20,30},{40,30} , 256})
among others, only crashing the program. It's a bit embarising being so
stumped by such a, I'm sure, simple thing :)

Hi Naflign,
It's mostly my fault because of me poor documentation.
You cant use a sequence for the Rectangler region. You will need
to make a structure and poke in the values, as an example:
-- Rect Structure for SURFACE_RECT_BLIT()
atom Rect
Rect = allocate(16)
.
.
.
poke4(Rect+0, 20) -- Left ( x coordinate )
poke4(Rect+4, 20) -- Top ( y coordinate )
poke4(Rect+8, 20+10) -- Right ( x + width of rectangle)
poke4(Rect+12, 20+10) -- Bottom( y + height of rectangle)
funcval = c_func( SURFACE_RECT_BLIT,{ Rect , 256})
Look at the GetPixel.exw example. I use the same function to draw
the palette in 8-bit depth mode.
Upcoming Exotica Update:
I'll stop what with I have for exotica now which is some bug fixes
for the CD_RESUME function, clear both surface buffers to black on
exotica initialization, can now draw outside of the screen without
crashing, full joystick support except for the forcefeedback joystick
and a couple of more examples.
I have other stuff to code before I can get to DirectPlay,
but for now, I will try to pretty up my documentation for the
rest of the week and try to release a minor update version 1.2 of
Exotica this coming weekend(Friday?). After that, I'll be right back
working on the poke4|mem_copy graphics to the surface part.
