Move a Character from point A to B trigger & on a spline direction

Hi, for better understand what I’ll want to create, i was made a short animation. [Look at please on YouTube][1]

Ok, now i’ll try explain to you what I can’t make now and not understand were to find answer.

  • Player move only on target points, from one to another.
  • On mouse click Player move to another target point on spline and rotate to right direction on spline.
  • We need to check, can we move to 2 or 3 target points. If we can, all available points is green and we can click and go to it. If no, point is red and we can’t move to it.

Thank’s for you answers!
