C++ : void TCODMap::computeFov(int player_x, int player_y, int maxRadius=0) C : void TCOD_map_compute_fov(TCOD_map_t map, int player_x, int player_y, int max_radius)
Parameter | Description |
---|---|
map | In the C version, the map handler returned by the TCOD_map_new function. |
player_x,player_y | Position of the player in the map. 0 <= player_x < map width. 0 <= player_y < map height. |
maxRadius | If > 0, the fov is only computed up to maxRadius cells away from the player. Else, the range is unlimited. |
C++ : TCODMap *map = new TCODMap(50,50); // allocate the map map->setProperties(10,10,true,true); // set a cell as 'empty' map->computeFov(10,10); // calculate fov from the cell 10x10 (unlimited range) C : TCOD_map_t map = TCOD_map_new(50,50); TCOD_map_set_properties(map,10,10,true,true); TCOD_map_compute_fov(map,10,10,0);
