Description:

public double closest_point (double x, double y, out double on_path_x, out double on_path_y, out int node_pos_before)

Figure out what and where on a path is closest to arbitrary coordinates.

Returns the length along the path where the closest point was encountered.

Parameters:

this

a Path

x

x coordinate.

y

y coordinate

on_path_x

return location for x coordinate on the path that was closest

on_path_y

return location for y coordinate on the path that was closest

node_pos_before

the node position interpreted before this position was deemed the closest coordinate.
