tarek2 Thank you so much. That's what i really wanted.
Actually, i spent so much time to figure out how to do this with pathfinding. lol, but it can be done without pathfinding. thats amazing
No problem mate, Glad that helped you :)
I just remembered now that C3 has the New Tween Behaviour will be helpful for saving on Overlaps checks, and has the On twin Finished Trigger which is nice.
Here is Demo if you are interested:

Note: for some reason, the Tween Behaviour is not working on the last C3 beta release R132 it gives a black screen use R131 instead if you have the same problem
