Paths
The following functions will give you information about a path:
path_exists(ind) Returns whether a path with the given index exists.
path_get_name(ind) Returns the name of the path with the given index.
path_get_length(ind) Returns the length of the path with the given index.
path_get_kind(ind) Returns the kind of connections of the path with the given index (0=straight, 1=smooth).
path_get_closed(ind) Returns whether the path is closed or not.
path_get_precision(ind) Returns the precision used for creating smoothed paths.
path_get_number(ind) Returns the number of defining points for the path.
path_get_point_x(ind,n) Returns the x-coordinate of the n'th defining point for the path. 0 is the first point.
path_get_point_y(ind,n) Returns the y-coordinate of the n'th defining point for the path. 0 is the first point.
path_get_point_speed(ind,n) Returns the speed factor at the n'th defining point for the path. 0 is the first point.
path_get_x(ind,pos) Returns the x-coordinate at position pos for the path. pos must lie between 0 and 1.
path_get_y(ind,pos) Returns the y-coordinate at position pos for the path. pos must lie between 0 and 1.
path_get_speed(ind,pos) Returns the speed factor at position pos for the path. pos must lie between 0 and 1.
