LineOfSight

A Haxe implementation of a line of sight algorithm from roguebasin

Usage:

using LineOfSight;

class Main
{

	static function main()
	{
		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:
