holoray_trail

Renders a holopad-style holoray from the parent item to a linked mob. The ray follows the pen, the linked mob, and any non-linked mob carrying the pen. Right-click while held toggles the trail; examine shows the current state.

Vars
enabled	Whether the ray is rendered when conditions allow it
holder_ref	Weakref to a non-linked-mob carrier whose movement the ray follows
holoray	The active ray overlay (only set while the mob is deployed and the trail is enabled)
linked_mob_ref	Weakref to the mob the ray points at
ray_color	Tint applied to the ray sprite; null leaves the default blue.
Procs
on_linked_mob_qdel	Self-destructs when the linked mob is deleted.
refresh_ray	Ensures the ray exists + points from the parent's turf to the linked mob's turf, or tears it down if it shouldn't exist.
update_holder_tracking	Tracks `COMSIG_MOVABLE_MOVED` on the parent's current carrier when it's not the linked mob, so the ray follows them.
