help: trigger removing hero

[Jooster]

i have a area in my map designated for a boss fight. all the boss's are hero units. but i also have a creep system. both types of units boss's/creeps are using the neutral hero because all other player slots are tied up with other units and events.

when i use this trigger

ashenvale creeps L2

        Set unit_group = (Units in (Playable map area) owned by Neutral Hostile)

replaced with

        Set unit_group = (Units in (Playable map area) owned by Neutral Hostile matching ((matching unit is a hero) equal to false)

It's freehand, but you'll find something like this

 

[Jooster]

Set unit_group = (Units in (Playable map area) matching (((Matching unit) is A Hero) Equal to False))

yes worked thanks!!

((Triggering unit) is A Hero) Equal to False
this was the problem, you should put picked unit instead of triggering
