Removing a unit's range of vision

[Zealot]

Is there a way without hiding or changing a unit's ownership to make that unit's owner not see what the unit sees or change it's sight range to 0?
Upgrades are not an option because they can't be removed and I want to make it possible to regain vision of that unit.
Any suggestions are appreciated.

You can set the unit's sight range to 0 and make a system of a following dummy unit with proper sight range that you can delete and recreate on whim. Moreover, you can have few kinds of different dummy units with different sight ranges to change your unit's sight range. This solution isn't recommended for large scale usage though.

The problem with 0 sight range is that you can't select the unit unless it's visible to other units you control. You could give it a very small sight range, but that still reveals units that come too close.

I need it for large scale usage though.

Making the unit unselectable by having 0 sight range is no problem because the unit would have it only under certain conditions that will eventually give the unit it's vision back.

You could try creating Line of Sight blockers that follow the target unit, thus restricting its vision. But then, this might be less effective than the dummy units.

Instead of using dummy units you can use visibility modifiers. I dont know if these can be moved with jass (maybe they can) but even if not they would probably still be cheaper then having dummy units. Units in general are pretty heavy-weight data containers in the wc3 engine.

• Visibility - Create an initially Enabled visibility modifier for (Owner of (Picked unit)) emitting Fog of war from (Position of (Picked unit)) to a radius of 1000.00

It blocks visibility for one second then it dissapears. The unit performs no action or moves at all.

Bump.

Visibility modifiers work only for 1 second, do I have to refresh them constantly or am I doing something wrong?

The visibility modifiers work permanent, but you do it wrong. Instead of trying to mask the area (which is getting unmasked by your unit again) you should remove the sight range of the unit and place a visibility modifier unmasking the area around the unit when you want it to be able to see anything.

The map is riddled with line of sight blockers, constant visibility modifiers instead of the unit's basic vision is not an option as it allows seeing over these blockers.

Is there a way to make a certain player's screen black or not allow him to see the map at all for some time?
