Hi.
Is it possible to get following one (target) sim to another going sim (actor)?
For example, if actor will move, then target sim must follow him.

Depends on what you plan to do. If you want an interaction of two sims happen in a certain position, you need to use a Jig that extends SocialJig and place it in the right position. If you want to have two sims move in a certain way, or a sim follow another one for doing something, you need a master interaction for the leading sim and and a slave interaction for the follower. You can extend the latter by having a "manager" interaction that keeps pushing the actual interaction(s) as continuation.

OK. Thank you.
But may be have something like



?

That's not how the routing works. A route has a fixed target. To implement the impression of a sim following a moving target, you'll have to continously route the sim. Like leader object is at point A, route follower sim to point A. When follower sim reaches point A, the leader object will be at point B already. So route the follower to point B now. And so on and so on.

What there is, is grouping of course. The thing you can use in the game too. It works basically the same, just that the game's core scripts do it for you.
