The health link is actually caused by a behaviour, not triggers.
If you look at the train units, they all have a Behaviour called Train Car - Conjoined. This is a Conjoined behaviour which means all units with this behaviour, within the range specified in the Behaviour's data, share hitpoints and when one is damaged all are damaged.
I'm trying to make Train boss for my usemap,
so I refered to campaign's trigger for make merged trains, but it totally confused me :(
Is there a good way to make health-linked trains?
