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.
