Tractor Beam Lock

When a beam catches a player or a living mob for real, the addon records which entity was taken and which head captured it. The victim is then held centered and kept moving toward that same head, so it cannot slip out halfway along the beam or drop away before it reaches the creature. The lock is released only when the situation calls for it, so the beam keeps its intended behavior in every other case.

The addon detects when an entity enters an active beam and treats that capture as a lock, which means getting caught really means getting caught. It works with both players and living mobs. It requires Cracker's Wither Storm Mod, and it is not a standalone mod: without the parent mod installed there is no Wither Storm to lock anything onto. Tractor Beam Lock is published for Forge 1.20.1 and is not open source, licensed as All rights reserved.

Tractor Beam Lock is one part of a pair. It handles the stage where the victim is carried toward the Wither Storm, while the Sickened Alive addon handles what happens after the victim is eaten. Together the two cover the whole sequence, and the author notes that the combination works great.
