How do I create enemies following simple waypoints using tween?

Can someone give me an example how to use tween as a waypoint for enemies?

I don't want to use Moveto or Pathfinding behavior cause I want its movement to be more precise.

you can interpolate in a property so that it moves only in one direction in a certain amount of time, this interpolation can be for a fixed value or for a value added to the current position of the object

MoveTo is a better choice here. You can adjust/disable the acceleration, deceleration and rotation values if you want.

With Tween you if the waypoints are at different distance from each other, you'll have to recalculate the tween duration every time.
