[Solved] Does "call BlzSetUnitRealField(whichunit,ConvertUnitRealField('umvh'),whichreal)" even work?

[GraduallyIBeganToHateThem]

So I'm trying to get the move height of a unit and transfer it to its related dummies.

Everything in this code below works, except "call BlzSetUnitRealField(tar,ConvertUnitRealField('umvh'),Usrc.ht)".

I tested it out, no matter which real value I set the argument to, it displays "0.000" in debug messages, and it also seems like Warcraft 1.31 doesn't allow access to 'umvh' field at all, as the result of "call utils_pr(R2S(BlzGetUnitRealField(whichunit,ConvertUnitRealField('umvh'))) )" shows, a zero comes out. at least on my end.

What is the problem here? Is it on me or Warcraft?

  unit u
  real fswm
  real bswm
  real lx

  real lz
  real lzs

  static method create takes unit u returns U
    local U newobj = U.allocate()
    set newobj.u = u
    set newobj.fswm = BlzGetUnitRealField(u,ConvertUnitRealField('ucpt'))
    set newobj.bswm = BlzGetUnitRealField(u,ConvertUnitRealField('ucbs'))
    set newobj.lx = BlzGetUnitRealField(u,ConvertUnitRealField('ulpx'))
    set newobj.ly = BlzGetUnitRealField(u,ConvertUnitRealField('ulpy'))
    set newobj.lz = BlzGetUnitRealField(u,ConvertUnitRealField('ulpz'))
    set newobj.lzs = BlzGetUnitRealField(u,ConvertUnitRealField('ulsz'))

[MyPad]

If it isn't in the list of defined unit object field constants, it isn't likely to work. Even so, there are some fields that straight up don't work.
You could use SetUnitFlyHeight and GetUnitFlyHeight instead for unit height-related matters.
