Active non-controllable units.

Hi, I would like to know how to do an active non-controllable unit, the controllable is no problem and I was thinking 'bout the "wander" spell to make the unit active and walk 'round little here and there, but when the unit is wandering it maybe attacks a unit, deals one or two blows and then runs away, how to change this that the unit will wander and attack enemies that gets close and doesn't continue wander be4 the target is dead?

Have a trigger order the unit to patrol to random points within somthing like 2000 of the unit. That would do the trick.

Yeah, it should work that way, but, do you need it to wander around the whole map? or just an area? I.E. Town, Forest, etc ...

It really wouldn't matter, if it was within a certain region all he would need to do is 'Patrol to (Random location within Region 001)' Infact that would make it easier sence there would be less chance of the unit trying to patrol into a river or somthing, given that there wouldn't be an unwalkable area in the middle of a town.

there by any chance you could make a trigger like that but they wander around within a say 600 yard radius of a hero and attack anything near them. sort of as a bodyguard or bodyguards.
