NetWar Graphics Engine revision history George Hoffman
---------------------------------------------------------------------------
v1.10 ■ Got around to sticking the code for enemies in there, and
modifying it for the new system
■ Sketched out menuing system - not really part of the engine,
but what the hell
v1.03 ■ Optimized wall calculation : 50 - 60% speed increase on
long views
■ Fixed wall-floor/ceiling meshing problem using a hybrid of
the old and new angling system
■ Optimized some critical timer-tick code
v1.02 ■ Added a lot of little stuff - optimizations
■ New angling/turning technique - takes less memory, and now
3600 possible facing directions instead of 128
■ New, MUCH more accurate ray-casting - cleans up
all the little "warps" (duplicate wall slices)
Little slower, I think, but not by much
■ Cleaned up movement speed handling
v1.01 ■ Fixed MAJOR but SUBTLE bug in keyboard routines. Interrupt
15h is trapped, and the previous interrupt was being called
in a manner which would satisfy many system calls, but not
those used by EMM386.EXE. This bug was transparent to me,
as I use QEMM. The net effect was that it either killed
you right off with a system crash or corrupted your memory
and hit you later when you tried to run a well-behaved app.
■ Implemented system independant movement speed.
■ Cleaned up memory de-allocation to save headaches later
v1.00 First release
