+# The Splines API
+
+Splines are another amazing UE4 feature.
+
+The following component shows how to move another actor over a spline path:
+
+```py
+class Spline:
+    def begin_play(self):
+        # get a reference to a spline component
+        self.spline = self.uobject.get_owner().get_actor_component_by_type(ue.find_class('SplineComponent'))
+        # find the length of the spline
+        self.max_distance = self.spline.get_spline_length()
+        self.distance = 0.0
+        # get a reference to the actor to move (as a blueprint property)
+        self.actor_to_move = self.uobject.get_owner().get_property('ObjectToMove')
+
+    def tick(self, delta_time):
+        if self.distance >= self.max_distance:
+            return
+        # find the next point on the spline
+        next_point = self.spline.get_world_location_at_distance_along_spline(self.distance)
+        self.actor_to_move.set_actor_location(next_point)
+        self.distance += 100 * delta_time
+```
