| 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. :) |
