Disable Auto-Attack

The question is simple: How do I retain attack but disable the auto-attack feature?

Worker classification. If added by triggers, it won't add the 'Idle Worker (F8)' thing. Don't think it stops auto-retaliate though...can't remember.

can't u do acqusition range = 0 so they wont find their own targets?
and yeah worker runs when hit, they dont fight back

Yes, setting acquisition range to 0 should disable auto attack

Err, no like said it disables their ability to find and hit stuff.

but setting it to 0 requires yourself to right click to attack, so that disables their ability to find and hit stuff

i want this feature thingf in my map also.

one method i considered was to set acquisition range to 0; then set it to the unit's attack range when it is issued an attack/smart-to-enemy order; then to set it back 0 when it is issued another, non-attack, order or when its order becomes null.

Another way to do it is to create an ability based off permanent invisibility, set its fade-time to -1, and disable auto-acquire.
