Typedef Documentation

MapSpace

typedef struct MapSpace MapSpace

This structure contains all information related to one map square.

mapstruct

typedef struct mapdef mapstruct

This is a game-map.

In general, code should always use the macros above (or functions in map.c) to access many of the values in the map structure. Failure to do this will almost certainly break various features. You may think it is safe to look at width and height values directly (or even through the macros), but doing so will completely break map tiling.

region

typedef struct regiondef region

This is a game region. Each map is in a given region of the game world and links to a region definiton, so they have to appear here in the headers, before the mapdef

rv_vector

typedef struct rv_vector rv_vector

This is used by get_rangevector to determine where the other creature is. get_rangevector takes into account map tiling, so you just can not look the the map coordinates and get the righte value. distance_x/y are distance away, which can be negative. direction is the crossfire direction scheme that the creature should head. part is the part of the monster that is closest. Note: distance should be always >=0. I changed it to UINT. MT

shopitems

typedef struct shopitem shopitems

Shop-related information for a map. This is one item type the shop will deal in, and the price-chance.

Function Documentation

map_size()

uint32_t map_size

(

mapstruct *

m

)

Calculate map size without intermediate sign extension.

Variable Documentation

map_layer_name

const char* const map_layer_name[MAP_LAYERS]

These correspond to the layer names in map.h - since some of the types can be on multiple layers, names are duplicated to correspond to that layer.
