Как заморозить юнита?

function HP takes nothing returns nothing 
local timer     t = GetExpiredTimer() 
local integer   d = GetHandleId(t)
local unit      u = LoadUnitHandle(udg_hash,d,0)
local real     hp = LoadReal(udg_hash,d,1)

 if GetUnitState(u,UNIT_STATE_LIFE) > 0.46 then 
  call SetUnitState(u,UNIT_STATE_LIFE,hp)
 endif  
set t = null 
set u = null 
endfunction 
function Zamorozka takes nothing returns nothing 
  local unit   u  = //ТВОЙ ЮНИТ 
  local real   hp = GetUnitState(u,UNIT_STATE_LIFE)
  local effect ef = AddSpecialEffectTarget("Лёд",u,"origin") 
  local timer   t = CreateTimer() 
  local integer d = GetHandleId(t)
   call PauseUnit(u,true)   
   call SetUnitTimeScale(u,0)
   
   call SaveUnitHandle(udg_hash,d,0,u)
   call SaveReal(udg_hash,d,1,hp)
   
  call TimerStart(t,0.01,true,function HP)  
   
   call TriggerSleepAction(Твое время)

   call DestroyEffect(ef) 
    cset u = null 
    set t = null 
    set ef = null
     
 

endfunction
