+===== Description =====
+Returns the length of the given 3D vector.
+===== Example =====
+Show 3D distance between actors:
+<code>
+int x = GetActorX(tid2) - GetActorX(tid1);
+int y = GetActorY(tid2) - GetActorY(tid1);
+int z = GetActorZ(tid2) - GetActorZ(tid1);
+int distance = length3d(x, y, z),
+print(s:"The two actors are ", f:distance, s:" mapunits apart in 3D space");
+</code>
+<note tip>Use [[ActorDistance]] instead of the example code above.</note>
