WatchDog custom functions

[setar]

'lo everyone,


I've been using a macro for a priest char -- it checks whether the current target already has a Renew HoT ticking. Now I'm struggling to integrate this with WatchDog's click-casting functionality. However, It checks the target instead of the char the mouse is currently hovering over.

function WD_SafeRenew(unit)

  local b = 1
  for j=0,15 do 
    a = UnitBuff(unit, j)
    if (a and string.find(a, "Renew")) then 
      b = nil
      break
    end
  end

  if (b) then 
    CastSpellByName("Renew")
  end

Could someone point me into the right direction? Thanks in advance!

	ClearTarget()
	CastSpellByName("Renew")
	SpellTargetUnit(unit)
	TargetLastTarget()
