Draw a Cube OutLine In GameMaker

Drawing cubes in GameMaker not using the D3D functions. Great for dice and other things.

draw_cube_outline() Where each square face line has a width of 1px

_point_h and _point_v should just be a number between 1 and -1 that shows the direction faces should point in.

Usage: draw_cube_outline(100,100,50,0.3,0.3,c_white)

function draw_cube_outline(_draw_x,_draw_y,_size,_point_h,_point_v,_colour) {
	
	var nodes = [[-1, -1, -1], [-1, -1, 1], [-1, 1, -1], [-1, 1, 1],
    [1, -1, -1], [1, -1, 1], [1, 1, -1], [1, 1, 1]];
 
	var edges = [[0, 1], [1, 3], [3, 2], [2, 0], [4, 5], [5, 7], [7, 6],
	[6, 4], [0, 4], [1, 5], [2, 6], [3, 7]];

	_point_h *= pi
	_point_v *= pi

	var sinX = sin(_point_h);
	var cosX = cos(_point_h);
 
	var sinY = sin(_point_v);
	var cosY = cos(_point_v);
	
	var number_of_nodes = array_length(nodes)
	for (var i = 0; i < number_of_nodes; ++i) {
	
		var node = nodes[i]

	    var _x = node[0];
	    var _y = node[1];
	    var _z = node[2];
 
	    node[0] = _x * cosX - _z * sinX;
	    node[2] = _z * cosX + _x * sinX;
 
	    _z = node[2];
 
	    node[1] = _y * cosY - _z * sinY;
	    node[2] = _z * cosY + _y * sinY;
	
		nodes[i] = node
	};

	draw_set_colour(_colour)

	var number_of_edges = array_length(edges)
	for (var i = 0; i < number_of_edges; ++i) {
	
		var edge = edges[i]
	
	    var p1 = nodes[edge[0]];
	    var p2 = nodes[edge[1]];
		draw_line(_draw_x+(p1[0]*_size),_draw_y+(p1[1]*_size),_draw_x+(p2[0]*_size),_draw_y+(p2[1]*_size))


	};

}

I want to say its not a real 3D model because it has no depth, but when we are always drawing to a 2D screen what even is 3D? Its just done by using sin and cos to find the lengths.

_point_h and _point_v should just be a number between 1 and -1 that shows the direction faces should point in.
