ITW/Moam3 cannons

Can anyone tell me how to make those cannons like in ITW or Moam3.. the ones that constantly shoot at you if you get within range.

just change the attack speed in object editor to desired value. and make it a building so that it wont try to follow u when u pass it.

And if u want to make it attack back and forth just have it attack a invisible shade while its patrolling.

Or, just make the missle speed around 200-320, the cooldown like .1 to .2, and change the units movement speed to Zero and its turn rate to 3.

Works fine, thats what i did, and like ach said have an invis unit patrol back and forth.

they dont shoot as fast as the itw moam3 cannons tho =/

you need to use a catapault as the base unit

ok thanks.
