<Question> How to make a unit unselectable?

I want a unit unselectable but damageable. (ex: acruiration attack, blizzard, etc...)

How to do that?

1) Set the selection scale to as small as possible (0.10).
This will decrease the chances of selecting the unit.
Now, if anyone actually does select the unit, have this trigger.

Event -- Player 1 selects <unselectable unit>
Action -- Select <some other unit>

Also, if you want the unit to be un-right-clickable

Event -- A unit owned by player 1 is issued an order targeting a unit
Condition -- Unit is equal to <unselectable unit>
Action -- Order <unit> to move to <unselectable unit>

give it the ability ALOC (from locust unit)

That crashes the game from my experiences...

the ALOC ability stops unit's from being damaged.

Events:
Game - Selection Event - A player selects an unit
Conditions:
Unit type of (triggering unit) = Unselectable unit type
Actions:
Remove (Triggering unit) from (Triggering player) selection

Even with that players will be able to click it for a mini second.

Thanks for help but...
I've tried both this trigger and Unknown(Aloc) before posting this article, sorry for not mentioned.

But the problems are that when using Unknown(Aloc), the unit will be undamageable (I want it damageable), and when using the former trigger, it works, but the player will still notice it...

Someone has a better idea??

I dunno id ir helps, but doodads can be unselectable and damagable.

In the TFT Object Editor, there is a thing "Selectable In Game" if you set that to false wouldn't you get what your looking for?

FYI - ALOC does several things. Its been awhile but if I recall it makes them invulnerable, unselectable, AND makes then move in a weird way so that they can go to a destination and then go back to the source. ALOC is only editable by changing the Ability Data SLK and turning ON the viewable in editor.
