Flying unchanged by Terrain?

[corvusHaunt]

Hmm, I'm making something top secret and I was wondering if anyone knew any way at all to make a flying unit's flight altitude unaffected by terrain. I mean how something like a Gyrocopter will fly over a hill, and change height.
Maybe some way to ignore terrain height while flying

Anyone have any suggestions, I'd appreciate it.

EDIT: Better way to explain:
How can I "ignore" the terrain beneath the unit, so I can keep the flying height level?

You could have a trigger check the height of the ground below the unit, and then have it change the height accordingly. For example for 1000 height all the time:

Every 1 seconds:

(Set (fly height) to (1000 - (Z of ground under unit)) over (1.1) seconds)

Might work...

Well I can't find it, but there is one in JASS.

set udg_TempReal = GetLocationZ(GetUnitLoc(udg_Your_Unit))

Please don't double post, especially 1 minute after eachother.
