path_spline in general starts at dist=0. To determine the nearest point on the path from an entity you can use:

Code:
var get_nearest_path_point(ENTITY* ent, char* pathname)
{
	ENTITY* e = ent_create(NULL, ent->x, NULL);
	path_set(e, pathname);
	var length = path_length(e);
	var optDist = 0;
	var entDist = 10000;
	
	var dist = 0;
	var vLastPos[3];
	var vDir[3];
	while(dist <= length)
	{
		path_spline(e,e.x,dist);
		dist += 5*time_step;
		if (vec_dist(e->x, ent->x) < entDist) {
			entDist = vec_dist(e->x, ent->x);
			optDist = dist;
		}
	}
        ptr_remove(e);
	return optDist;
}


So you can, for instance, spawn an entity next to the player and the entity knows at what distance it should start path_spline to directly start at the nearest position to the path.
