Help With changing a character into a projectile

Hello can i please have some more help with this.
The problem is getting a character to act like a homing projectile under a certain condition.
In my game when a enemies health get low i want them to fly toward the player character, just aiming at the player character.
In the game dragon ball if the dash button is pressed.The characters will fly toward the enemy.
I want this effect exactly.
Please help.I have tried the answer to the question in

my past posting but its not working.

It should work if you just start interpolating their location and orientation towards the player. Is there anything wrong with this approach?

thank you bro, I will try it out.
