Anybody can help me with homing missile spell?

I am trying to create homing missile type of magic spell.
I am finding the enemy with LineTraceForObjects(). after hours of debugging I still can’t get it to working. I was following this - ( tutorial.

I have included screenshots of my BluePrints - (Imgur: The magic of the Internet).

1st image of targeting enemy

2nd image of spawning missiles

Please tell what is wrong?

  1. Use projectile movement component
  2. In PMC, set checkbox homing missile (or is homing) to true
  3. On spawn projectile (spell) set homing target component of your target, i think it must be scene component like mesh, or create dummy scene component in target actor and set its position to head or body or where you want
