Getting terrain height

zen87	Well just wondering... how to get terrain heigh ? currently im using a stupid method of getting a unit's real height JASS: function GetUnitZ takes unit u returns real return (GetLocationZ(GetUnitLoc(u))+GetUnitFlyHeight(u)) endfunction any other simple native ?

blu_da_noob	There is no other way to get terrain height. And that leaks a location.

zen87	yes yes i know... was lazy to type out the full leakless code... anyway here's my full function of GetUnitZ, seriously there is no other easier way ? I hate using locations for some lame reason JASS: function GetUnitZ takes unit u returns real local location l = GetUnitLoc(u) local real z = (GetLocationZ(l)+GetUnitFlyHeight(u)) call RemoveLocation(l) return z endfunction

blu_da_noob	No one likes using locations for it, but there is currently no other option. And just a warning, that function of yours won't return an accurate Z height for flying units. There is a smoothing factor built into the height system which will screw it up. And you will also want to null that location.

grim001	It would also be faster if you moved a global location to X and Y of the unit instead of creating a new location; creating new handles is slow.

well at the very least we could get a value that very close to the actual height of the unit =\

grim001 : oh yeah !! thanks for reminding me that, kay now shouden't have any problem now!

JASS:

globals
    private location L = Location(0,0)
endglobals

private function GetUnitZ takes unit u returns real
    call MoveLocation(L,GetUnitX(u),GetUnitY(u))
 return GetLocationZ(L)+GetUnitFlyHeight(u)
endfunction
