SetBeamForceLocalEnd(<-beamUID <-forceLocalEnd)

When set to true on a beam, the beam will use local coordinates for the end point when attached to a unit. Normally, the end point of a beam is always in global coordinates even when the beam is attached to a unit. If you want the end point to also be relative to the unit, then SetBeamForceLocalEnd to true.

   #Fire a beam to extends off screen but is at the same height as the unit
   #We will attach the beam to ourselves, so that the start point is relative to our unit
