class LineOfSight<T>

package zero.utilities

A Haxe implementation of the line of sight algorithm on [roguebasin]()

Usage:

var map_data = [
	' ########       '.split(''),
	' #......#       '.split(''),
	' #......#       '.split(''),
	' #......####### '.split(''),
	' ####.####....# '.split(''),
	'   #..........# '.split(''),
	'   #...###....# '.split(''),
	'   ##### ###### '.split(''),
];
var los = new LineOfSight({ map: map_data, walls: ['#'] });
var p = { x: 5, y: 5 };

los.fov(p.x, p.y, 6);
for (row in los.place_char(los.get_lit_map('?'), '@', p)) trace(row.join(''));

Output:
