◆ mapdata_bigface()

gint16 mapdata_bigface	(	int	x,
		int	y,
		int	layer,
		int *	ww,
		int *	hh
	)

Returns the face to display at a given location. This function returns the "tail" information, i.e. big faces expanded by the client.

*ww and *hh return the offset of the current tile relative to the head; 0 <= *ww < (width of face), 0 <= *hh < (height of face).

When drawing the map view, this function must be used instead than a direct access to the_map.cells[]. This is because the_map.cells[] eventually still contains obsolete (fog of war) big face information; this function detects and clears such faces.

Return the face number of a multi-square pixmap at the given map tile.

Parameters

x	X-coordinate of tile on-screen
y	Y-coordinate of tile on-screen
layer
ww
hh

Returns: Pixmap face number, or zero if the tile does not exist

Returns the face to display at a given location. This function returns the "head" information, i.e. the face information sent by the server.

Return the face number of a single-square pixmap at the given map tile.

Parameters

x	X-coordinate of tile on-screen

◆ mapdata_face_info()

gint16 mapdata_face_info	(	int	mx,

Return the face number of the pixmap in the given map cell and set the offset pointers to indicate where to correctly draw the face. Offsets are zero for single-tile maps and negative for multi-tile maps. This provides a consistent way to draw tiles no matter single or multi part.

Parameters

mx	Virtual map x-coordinate
my	Virtual map y-coordinate
layer	Map layer number
dx	Pointer to store x-offset
dy	Pointer to store y-offset

Returns: Pixmap face number, zero if the tile does not exist
