How can i do so that allies can NOT attack eachother?

[Yiux]

I am making a map of course
In the map there are 8 players, and they are all enemies.
but there is a zone where they should not be able to attack eachother. I have tried to make the units ancients and then disabled the "Can attack ancients"
However they can still attack eachother. Can I get a hint or anything?
Then i would be very happy

Pastebin - The Hive Workshop - Warcraft 3 Maps, Icons, Spells, Tools, Tutorials, Skins, Models, Campaigns, Scenarios here is a example

 

[Huurka]

A unit is issued an order targeting a unit
if unit is friend of targeted unit

order unit to stop.

 

[Yearight]

that would leak, remember to set a variable. And its only in a region.

 

[Huurka]

It does?

 

[Yearight]

yes, the "triggering unit" would be used serveral times.

And btw im sorry to get off topic.

 

[Huurka]

Triggering unit is a local.

 

[Yearight]

mmh.. sorry then, my bad

 

[Yiux]

Will that work with abilities too?

 

[Anarki]

Make them invulnerable?

Or maybe ally them while they are in the region?

make this

''unit enters region ''Safe Zone''

Make Triggering unit Invulnerable''

''unit leaves region ''Safe Zone''

Make Triggering unit vulnerable''
