Pathing and vision related question

[Death Adder]

If a unit is ordered to move to a location wc3 will give it the shortest path there.

Now if the path becomes obstructed without the player having vision would another unit issued to move after this change have his path changed possibly without ever seeing that the previous path is obstructed or will the second unit try to move like the first until it finds out it can't?

The point is if i could manipulate this to make units move differently depending on each players vision

Without knowing the indepth answer to this. I believe whenever a new pathing blocker (doodad, building etc) is generated all units will know.
It just makes sense I guess. Otherwise units would get stuck all the time because of lack of vision.

Yeah I think so too, units already moving don't get this though I think?

Or atleast it updates slowly

You can easily test this.
Create two cliffs with a small passage through which leaves enough space for a unit to travel and enough space for some pathing blocker.
Place a unit so the shortest route to the other side goes through the passage.
Create a trigger that spawn a pathing blocker in the passage a few seconds after the unit is ordered to move.
The order should point to the other side of the cliffs.

Look at the results.

As far as I remember unit will try to walk like the path was not blocked.

Yeah the unit moved until something like 500 units close, thinking it might be based on acusition range

Edit: Nope it doesn't seem to change from anything I find. Probably not going to be useful...
