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:
|
||||
ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿
|
||||
³ Sector lists: Status lists: ³
|
||||
ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´
|
||||
³ Sector0: 4, 5, 8 Status0: 2, 0, 8 ³
|
||||
³ Sector1: 16, 2, 0, 7 Status1: 4, 5, 16, 7, 3, 9 ³
|
||||
³ Sector2: 3, 9 ³
|
||||
ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
|
||||
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 32-bit offset 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.
