Thank you for your answer!
Right now what makes the leader moving is a simple loop animation inside the symbol (not in the main timeline), just up/down movement. Is it different if the movement is causes by the code?
Actually I want it to be practical, which means that I could change the movement of the leader if I want to, the follower will follow anyway. I don't think I would move the leader by code but I may so... If this is an important point I should decide now I guess!
I'm not really a coder... So if you have some time to write something for me, I would really appreciate it!
Let's say my first symbol is called crow_01 (leader), my second is called crow_02 (follower), and the movement is done by symbol's timeline animation (let's put the movement by code aside for now).
Thank you very much!
