POSITION VARIABLES:
|
|
|
|
POSX is your x - position ranging from 0 to 65535
|
|
POSY is your y - position ranging from 0 to 65535
|
|
(the length of a side of the grid in EDITBORD would be 1024)
|
|
POSZ is your z - position (height) ranging from 0 to 65535, 0 highest.
|
|
ANG is your angle ranging from 0 to 2047. Instead of 360 degrees, or
|
|
2 * PI radians, I use 2048 different angles, so 90 degrees would
|
|
be 512 in my system.
|
|
|
|
SPRITE VARIABLES:
|
|
|
|
EXTERN short headspritesect[MAXSECTORS+1], headspritestat[MAXSTATUS+1];
|
|
EXTERN short prevspritesect[MAXSPRITES], prevspritestat[MAXSPRITES];
|
|
EXTERN short nextspritesect[MAXSPRITES], nextspritestat[MAXSPRITES];
|
|
|
|
Example: if the linked lists look like the following:
|
|
????????????????
|
|
Sector lists: Status lists:
|
|
????????????????J
|
|
Sector0: 4, 5, 8 Status0: 2, 0, 8
|
|
Sector1: 16, 2, 0, 7 Status1: 4, 5, 16, 7, 3, 9
|
|
Sector2: 3, 9
|
|
????????????????
|
|
Notice that each number listed above is shown exactly once on both the
|
|
left and right side. This is because any sprite that exists must
|
|
be in some sector, and must have some kind of status that you define.
|
|
|
|
|
|
TILE VARIABLES:
|
|
NUMTILES - the number of tiles found TILES.DAT.
|
|
|
|
TIMING VARIABLES:
|
|
NUMFRAMES - The number of times the draw3dscreen function was called
|
|
since the engine was initialized. This helps to determine frame
|
|
rate. (Frame rate = numframes * 120 / I_GetBuildTime().)
|
|
|
|
OTHER VARIABLES:
|
|
|
|
STARTUMOST[320] is an array of the highest y-coordinates on each column
|
|
that my engine is allowed to write to. You need to set it only
|
|
once.
|
|
STARTDMOST[320] is an array of the lowest y-coordinates on each column
|
|
that my engine is allowed to write to. You need to set it only
|
|
once.
|
|
SINTABLE[2048] is a sin table with 2048 angles rather than the
|
|
normal 360 angles for higher precision. Also since SINTABLE is in
|
|
all integers, the range is multiplied by 16383, so instead of the
|
|
normal -1<sin(x)<1, the range of sintable is -16383<sintable[]<16383
|
|
If you use this sintable, you can possibly speed up your code as
|
|
well as save space in memory. If you plan to use sintable, 2
|
|
identities you may want to keep in mind are:
|
|
sintable[ang&2047] = sin(ang * (3.141592/1024)) * 16383
|
|
sintable[(ang+512)&2047] = cos(ang * (3.141592/1024)) * 16383
|
|
NUMSECTORS - the total number of existing sectors. Modified every time
|
|
you call the loadboard function.
