Trigger-based Truesight?

[777devil777]

Little problem with Blizzard's truesight. Truesight units only have to be nearby as if truesight is a aura. (They don't even need to be able to see the unit.)

For example:




|-----|
|-----|
|-----|

(Assume the lines = cliff, orc = invisible unit, yellow guy = truesight unit, and the laughing guy is a flying unit.)

The yellow guy has truesight so he can see invisible units, but he can't see anything on top of the cliff.

The allied flying unit comes along (Without truesight), and the invisible unit is seen.

So I'm wondering... Are there any ways to make a invisible unit only show if a truesight unit can actually see them? Special editing/ Jass?

There's a way, but I'm not familiar with it.
