This is a quick hack of Quake ported to the Simple DirectMedia Layer library.
|
||
|
|
http://www.devolution.com/~slouken/SDL/
|
||
|
|
|
||
|
|
To build under Linux, simply run ./configure; make
|
||
|
|
|
||
|
|
This game requires the original Quake datafiles. You can get the shareware
|
||
|
|
data files from http://www.idsoftware.com/.
|
||
|
|
|
||
|
|
Of interest in the original X sources is the following:
|
||
|
|
// Duff's Device
|
||
|
|
count = width;
|
||
|
|
n = (count + 7) / 8;
|
||
|
|
dest = ((PIXEL16 *)src) + x+width - 1;
|
||
|
|
src += x+width - 1;
|
||
|
|
|
||
|
|
switch (count % 8) {
|
||
|
|
case 0: do { *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 7: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 6: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 5: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 4: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 3: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 2: *dest-- = st2d_8to16table[*src--];
|
||
|
|
case 1: *dest-- = st2d_8to16table[*src--];
|
||
|
|
} while (--n > 0);
|
||
|
|
}
|
||
|
|
This idea may make it into the SDL blitters if it turns out to be faster
|
||
|
|
than my current code. :)

Thanks to Zoid, Dave Taylor, John Carmack, and everyone else involved in the
|
||
|
|
open source release of id games. :)
