Sidewinders (mm hunter) have 2 stacks, and i need the condition to dont let reach 2 stacks, always cast when reach 2 stacks. or even better, cast it when is about to reach 2 stacks.

Dont work, because it checks the buff on your character, not the stack of the skill on your skill bar.

GetSpellCharges do, what you want. Its not difficult to check if there are 2 charges. But it could very difficult to check, if you used one before (and want now used the second one). With my Sub-Rogue i can check a buff (31223) which exist 5 sec's longer then shadowdance (185313). (but only if a special talent used)

 

local spellname=GetSpellInfo(36554)  --[[ Shadowstep ]]
if UnitExists("target") and not UnitIsFriend("player", "target") and (IsSpellInRange(spellname,"target")==1) and (UnitHealth("target")>1) then
	local currentCharges, maxCharges, cooldownStart, cooldownDuration = GetSpellCharges(185313)
	local now=GetTime();
	if (currentCharges>=2) or ((UnitBuff("player",GetSpellInfo(31223))~=nil) and (currentCharges~=0)) then
		result=true
		--[[ Stealth, Shadow Dance or Subterfuge ]]
		if IsStealthed() or (UnitBuff("player",GetSpellInfo(185313))~=nil) or (UnitBuff("player",GetSpellInfo(108208))~=nil) then
			result=false
		end
	end
end
