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 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=0 for a particular palette // how: pass -1 to invalidate all instances of the tile in texture memory, or a bitfield // bit 0: opaque or masked (non-translucent) texture, using repeating // bit 1: ignored // bit 2: 33% translucence, using repeating // bit 3: 67% translucence, using repeating // bit 4: opaque or masked (non-translucent) texture, using clamping // bit 5: ignored // bit 6: 33% translucence, using clamping // bit 7: 67% translucence, using clamping // clamping is for sprites, repeating is for walls void invalidatetile(short tilenume, int pal, int how); int animateoffs(short tilenum, short fakevar); void setpolymost2dview(void); // sets up GL for 2D drawing int polymost_drawtilescreen(int tilex, int tiley, int wallnum, int dimen, int tilezoom); void polymost_glreset(void); void polymost_precache(int dapicnum, int dapalnum, int datype); #if defined(POLYMOST) && defined(USE_OPENGL) extern int glanisotropy; extern int glusetexcompr; extern int gltexfiltermode; extern int glredbluemode; extern int glusetexcache, glusetexcachecompression; extern int glmultisample, glnvmultisamplehint; extern int glwidescreen, glprojectionhacks; void gltexapplyprops (void); extern int r_depthpeeling, r_peelscount; extern int r_detailmapping; extern int r_glowmapping; extern int r_vertexarrays; extern int r_vbos; extern int r_vbocount; extern int r_animsmoothing; extern int r_parallaxskyclamping; extern int r_parallaxskypanning; extern int r_modelocclusionchecking; extern int r_fullbrights; extern int r_downsize; extern int mdtims, omdtims; #endif void hicinit(void); // effect bitset: 1 = greyscale, 2 = invert void hicsetpalettetint(int palnum, unsigned char r, unsigned char g, unsigned char b, unsigned char effect); // flags bitset: 1 = don't compress int hicsetsubsttex(int picnum, int palnum, char *filen, float alphacut, float xscale, float yscale, char flags); int hicsetskybox(int picnum, int palnum, char *faces[6]); int hicclearsubst(int picnum, int palnum); int Ptile2tile(int tile, int pallet); int md_loadmodel(const char *fn); int md_setmisc(int modelid, float scale, int shadeoff, float zadd, int flags); int md_tilehasmodel(int tilenume, int pal); int md_defineframe(int modelid, const char *framename, int tilenume, int skinnum, float smoothduration, int pal); int md_defineanimation(int modelid, const char *framestart, const char *frameend, int fps, int flags); int md_defineskin(int modelid, const char *skinfn, int palnum, int skinnum, int surfnum, float param); int md_definehud (int modelid, int tilex, double xadd, double yadd, double zadd, double angadd, int flags); int md_undefinetile(int tile); int md_undefinemodel(int modelid); #define MAXPALCONV 200 void clearconv(); void setpalconv(int pal,int pal1,int pal2); void getpalmap(int *stage,int *pal1,int *pal2); int checkpalmaps(int pal); void applypalmap(char *pic, char *palmap, int size, int pal); int loaddefinitionsfile(char *fn); extern int mapversion; // if loadboard() fails with -2 return, try loadoldboard(). if it fails with -2, board is dodgy int loadoldboard(char *filename, char fromwhere, int *daposx, int *daposy, int *daposz, short *daang, short *dacursectnum); // Hash functions struct HASH_item // size is 12/24 bits. { const char *string; int key; struct HASH_item *next; }; struct HASH_table { int size; struct HASH_item **items; }; void HASH_init(struct HASH_table *t); void HASH_free(struct HASH_table *t); int HASH_findcase(struct HASH_table *t, const char *s); int HASH_find(struct HASH_table *t, const char *s); void HASH_replace(struct HASH_table *t, const char *s, int key); void HASH_add(struct HASH_table *t, const char *s, int key); #ifdef _MSC_VER #pragma pack() #endif #ifdef __WATCOMC__ #pragma pack(pop) #endif #undef BPACK #ifdef __cplusplus } #endif #endif // __build_h__
