void adjust_tile_stretch ( )

Adjust the tile stretch of a map.

Goes through the whole map and for each coordinate calls align_tile_stretch() in all directions. This is done to fix any inconsistencies, since the map command doesn't send us the whole map all over again, but only new/changes parts.

Definition at line 315 of file map.c.

void align_tile_stretch	(	int	x,
		int	y

Align tile stretch based on X/Y.

Parameters:

x	X position.
y	Y position.

Definition at line 216 of file map.c.

static int calc_map_cell_height	(	int	x,
		int	y
	)		`[static]`

Calculate height of X/Y coordinate on ::the_map.

Checks for X/Y overflows.

Parameters:

x	X position.
y	Y position.

Returns:: The height.
