How to make units attack any unit in a region?

I need Player 12 units to attack any unit that is:
A hero
An Ally of player 1 (red)

in a region

what triggers i must use for this?

 

[AceHart]

Aren't they doing this anyway if some enemy gets near?
If you ordered them to move around, change the order from "move" to "attack-move".

i need them to attack ANY enemy hero who is in the arena.
If someone hides his hero behind barricades or somwhere else in the arena and tries to hide from the creeps, the creeps automaticaly attack them without needing a enemy getting close to them.

so creeps hunt down the enemies?

 

[NightMagi]

yes

an if trigger?
every 20 seconds
set temp group = region matching (matching unit belongs to an ally of player 1)
if
number of units in temp group is equal to or bigger than 1
pick every unit in playable map area matching (matching unit belongs to neutral hostile)issue order order picked unit to attack random unit in temp group
or
every 0.2 seconds
order unit to attack move (smart I think) to position of random unit in temp group with offset 20, 20
this way the hunting is faster and creeps dont stand there randomly
