[General] How do neutral hostile units choose their target

[Marebre]

I am not sure I'm posting this in the right forum, but here it goes:

How do neutral hostile units (aka creeps), or, for that matter, computer-controlled player units choose their attack target if surrounded by more than one enemy?

Do they check armor, level, type (building, unit, Hero, ward etc.), distance, current lunar phase, or something else? Or everything combined?

This question is so general, and almost certainly has been asked before, however, I can't find any such thread.

I did find this thread explaining how creeps choose their spell targets, though.

As far I am aware they attack whatever is closest.

OR

Whoever attacks it first.

And I think they prioritize unit's attacks rather than building's.

 

[Xonok]

They choose the highest priority targets in their acquisition range. Also, this.

There are lots of factors that influence this. For example, if one of your units is attacking one of your own units, your unit will be deprioritized compared to other units that are attacking the computer controlled unit.

And they will chase your heroes to the end of the world if they don't have a creep return distance.

Personally I'd like to know a way to completely remove their behaviour.
