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.
|
|
|
|
|
|
Coding example #1:
|
|
To go through all the sprites in sector 1, the code can look like this:
|
|
|
|
sectnum = 1;
|
|
i = headspritesect[sectnum];
|
|
while (i != -1)
|
|
{
|
|
nexti = nextspritesect[i];
|
|
|
|
//your code goes here
|
|
//ex: printf("Sprite %d is in sector %d\n",i,sectnum);
|
|
|
|
i = nexti;
|
|
}
|
|
|
|
Coding example #2:
|
|
To go through all sprites with status = 1, the code can look like this:
|
|
|
|
statnum = 1; //status 1
|
|
i = headspritestat[statnum];
|
|
while (i != -1)
|
|
{
|
|
nexti = nextspritestat[i];
|
|
|
|
//your code goes here
|
|
//ex: printf("Sprite %d has a status of 1 (active)\n",i,statnum);
|
|
|
|
i = nexti;
|
|
}
|
|
|

insertsprite(short sectnum, short statnum);
|
|
deletesprite(short spritenum);
|
|
changespritesect(short spritenum, short newsectnum);
|
|
changespritestat(short spritenum, short newstatnum);
|
|
|
|
TILE VARIABLES:
|
|
NUMTILES - the number of tiles found TILES.DAT.
|
|
TILESIZX[MAXTILES] - simply the x-dimension of the tile number.
|
|
TILESIZY[MAXTILES] - simply the y-dimension of the tile number.
|
|
WALOFF[MAXTILES] - the actual address pointing to the top-left
|
|
corner of the tile.
|
|
PICANM[MAXTILES] - flags for animating the tile.
|
|
|
|
TIMING VARIABLES:
|
|
TOTALCLOCK - When the engine is initialized, TOTALCLOCK is set to zero.
|
|
From then on, it is incremented 120 times a second by 1. That
|
|
means that the number of seconds elapsed is totalclock / 120.
|
|
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 / totalclock.)
|
|
|
|
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.
