The picture doesn’t tell us much since we don’t know what we’re supposed to be looking at.
Is the black and red image the Beam?
What do you want the Beam to look like compared to what the image shows?
Beams run from 1 Attachment to a 2nd Attachment so if you want it to align from the player to the Position it’d have to have Attachments at both ends.
If you want the Beam to look like the black and red image is moving away or to the player then a Beam probably isn’t what you need and @MykoNil’s suggestion might work better.
