Precisely setting a -flying- unit's flyheight

[iNfraNe]

Hello,

I am trying to set a flying unit's FlyHeight to a precise value. I need it to have flying pathing, because I want it to use the pathing blockers for flying units only.

The problem is: flying unit's height gets smoothed if there's uneven terrain nearby. I want the flying height to be exactly what I set it to, like it if for "ground" units with the 'Amrf' trick.

Is there some sort of hack, or does anyone know the formula which blizzard uses to calculate the Z increase (in a similar fashion to this: http://www.hiveworkshop.com/forums/jass-resources-412/system-getcamoffset-131434/)

Thanks,

Setting the fly height considering the terrain Z is the way to go.

I think it involved making the unit "floating" or something like that.

Setting the fly height considering the terrain Z is the way to go.

Cliffs and doodads (or was it destructibles?) provide some form of fly height deformation which makes units fly higher than simply considering the terrain Z.

Apparently "float" movement ignores this deformation (useful for absolute height missiles) but that probably is not flying so not viable for your purpose.

It can be Usable if we add'n'remove 'Arav'.

Thanks guys,

I got it to work with float and naval pathing.

EDIT: well, not quite. Floating units are also blocked by ground pathing blockers...

Is there a way by which I can let floating units pass, while blocking normal ground units?

That requires a Custom pathing System.

You can use IsPointWalkable by PurgeandFire as well.

Actually, I found a slightly non-elegant solution:

//! externalblock extension=lua PathMapper $FILENAME$
    //! i function all(tileid, cliff, layer)
    //! i   return true
    //! i end
    //! i function setwaternofly()
    //! i   if not isflagset(nofly) then
    //! i       removeflags(nowater)
    //! i   end
    //! i end
    //! i registercallback(all,setwaternofly)
//! endexternalblock

this turns the entire map pathable for floating units, except where the map has flying blockers (only doodad based, not destructable). This problem is now "solved" Thanks for the help.
