Stars DLL
This DLL creates a starfield in the background, easy to use:
Code: |
PROGRAM stars;
IMPORT "stars.so";
PRIVATE
mapa1;
BEGIN
mapa1=load_map("..\stars\prueba.map");
graph=mapa1;
loop
x=320;
y=240:
set_mode(m640x480);
frame;
// parametros
// velocidad,direccion,numerodepuntos,modo,color
put_stars(16,8,800,1,255);
WHILE(scan_code!=32)
FRAME;
END
quit_stars();
frame;
WHILE (scan_code==32)
FRAME;
END
// parametros
// velocidad,direccion,numerodepuntos,modo,color
put_stars(4,0,800,1,255);
frame;
WHILE (scan_code==32)
FRAME;
END
quit_stars();
set_mode(m320x200);
frame;
x=160;
y=100:
graph=mapa1;
WHILE (scan_code==32)
FRAME;
END
// parametros
// velocidad,direccion,numerodepuntos,modo,color
put_stars(1,3,400,1,15);
WHILE (scan_code!=32)
FRAME;
END
quit_stars();
frame;
WHILE (scan_code==32)
FRAME;
END
end
END

Thanks for posting this Mike, very interesting. I've got an idea for an extension I'd like to try to write but we'll see if I ever get around to it,
I've got some documentation to finish first!

DIV extensions are incredibly easy to write, but having the idea in the first place is the hard part.
At some point I'll write up some docs on how to compile for each platform and what pitfalls to avoid.

I thought I'd give it ago, apparently I need div.h
Is that available anywhere or shall I patiently wait until you get a chance to write up some instructions? I'm honestly in no rush, I was just having
a play.

I thought div.h was in one of the packages. But since i can't find it, have this one.
Code: | gcc dll.c -o dll.so -fPIC -funsigned-char -shared |
If you are building for windows, you need to use -o file.dll

Well, it compiles (with 5 warnings, but I assume that they're normal)
I then placed stars.prg, stars.so and prueba.map all in the same dir and updated the load_map call to just "prueba.map". I try to execute, compile or
debug it and I get "Use of an invalid external DLL". I've tried chmodding the stars.so file 777 just to be sure it's not a permissions thing but to no
avail.
This is with beta 12 on Mac.

You should use the full path to your stars.so in your prg, or copy stars.so into the app bundle in the same dir as d-OSX
