Function Documentation

generator_init_topology()

void generator_init_topology

(

bool

autosize

)

This function sets sizes in a topology-specific way then calls map_init_topology().

Set 'autosize' to TRUE if the xsize/ysize should be calculated.

Definition at line 285 of file mapgen_topology.cpp.

Referenced by map_generate().

get_sqsize()

int get_sqsize

(

)

An estimate of the linear (1-dimensional) size of the map.

Definition at line 399 of file mapgen_topology.cpp.

Referenced by generator_init_topology(), make_fracture_hmap(), and make_random_hmap().

map_colatitude()

int map_colatitude

(

const struct tile *

ptile

)

Returns the colatitude of this map position.

This is a value in the range of 0 to MAX_COLATITUDE (inclusive). This function is wanted to concentrate the topology information all generator code has to use colatitude and others topology safe functions instead (x,y) coordinate to place terrains colatitude is 0 at poles and MAX_COLATITUDE at equator

Referenced by create_tmap(), hmap_pole_factor(), make_pseudofractal_hmap(), make_river(), normalize_hmap_poles(), place_terrain(), and renormalize_hmap_poles().

near_singularity()

bool near_singularity

(

const struct tile *

ptile

)

Return TRUE if the map in a typical city radius is SINGULAR.

This is used to avoid putting (non-polar) land near the edge of the map.
