Beam attack, need help


I am trying to make a beam attack with my AI, I want my AI to cast the beam on the Character position and then rotate to where my Character is moving for like 2 seconds.

Right now I am using 2 line trace to get the character position. How can I get the area between these 2 traces? or how can I move one line trace to another point?

If you know a better way to do this please tell me, thanks :slight_smile:
