Invisibility question

[RobertMKD]

Hey hivers!
I'm striking with a question again: Is it possible to make a unit invisible only to a certain player? If so, how?

 

[Dr Super Good]

Invisibility is a flag. It affects either all players (on) or no players (off). As such it is not possible.

However, you could reveal it for all but specific players. If you give all other players detection of the unit then it will be "invisible" as far as the flag is concerned but not invisible to those players.

Yes, using GetLocalPlayer().

No, that would control invisibility for specific clients, not players. On those clients it would either not be invisible to all players, or be invisible to all players. It will also more than likely cause the clients to OOS if used in combat.

A very shitty way of only making it invisible for a player:
Give the unit the invisibility ability.

Then for all the players that should be able to see the invisible unit, make give them the true sight ability to their units. You can use a spellbook to hide the icon if you want.

For the player who should not see the invisible unit, simply do not give the true sight ability to hen.

Might work in an ideal world where no players ally with each other.

You can have allies without sharing vision.

I didn't say it was a good solution, just that it's an option if he really needs it

But that will also show the other nearby invisible units. I wonder how dust works, does it reveal invisible only to the owner of the caster or to everyone?

Are you talking about the trigger "flag"? I can't understand you well.

 

[LordDz]

Dust reveals all invisible units in the radius to all players allied to the owner of the casting unit.

 

[RobertMKD]

You see, that's exactly what I need!
I'll create a dummy unit at the position of the invisible unit, and cast dust (which AOE is modified to 1 and duration to 1 sec) every 1 sec if it fulfills the condition. What do you say about that?

 

[NightStalker]

For which player(s) will you create the dummy for? If you have allied vision on and put a dummy for a player from that allies all of them will be able to see it. If that's what you wanted, I guess that works.

 

[RobertMKD]

There's no allies in my map. The only thing that buggs me is the buff of Dust. Will it work without the buff? And can Dust be cast on one unit by multiple units owned by different players at once?

 

[Wietlol]

You should not use the GetLocalPlayer for this because this affects unit's behavior.
(Yes it does.)

As DSG and LDZ mentioned:
What you could do is make them invisible to all players and for the ones who should see them, you could give those a dummy unit with true sight.

However... why not give that dummy unit a dummy true sight with 1 range?
That dummy will follow the target in a 0.03 interval so it will keep the other in sight.
It will also not show nearby invisible units as the range is too low for that.

That would be the best guess I think...
However, there might be another way to achieve what you want.

 

[Dr Super Good]

Tried using "Faerie Fire"? This might only work to reveal the unit to 1 player at a time however (non-stacking WC3 buffs).
