/**
* Dragger beams pull a selected player towards their center
*
* Dragger beams are generated by a particular dragger for the player closest to it and for whom certain criteria are
* met. Dragger beams exist until these criteria are no longer met. Dragger beams dissolve and automatically
* de-register from their dragger source as soon as the player for whom they were created:
* - is no longer alive
2022-05-09 12:03:00 +00:00
* - is no longer in range (sv_dragger_range)
* - can no longer be dragged because the beam is intercepted by a laser stopper (or if !IgnoreWalls by solid blocks)
*
* Dragger beams accelerate the selected player every tick towards their center. The length of the speed vector, which
* is added to that of the player, depends only on the strength of the dragger and is between 1 and 3 units long. If
* the player is in the center of the dragger, it will not accelerate.
