[lekken]

I know its for 5+, i try to make it for 4.3.4, but its dont load, is this api on 5+ other?

I need only a script that make Shadow Word: Death, when a Hunter use Scatter Shot or Rogue use Blind.
No Spell Check or other shit, so simple ..

--[[ AntiCCv3 EPvP Pand0r]]--

--[[ Settings ]]--
local Spells1 = {"Scatter Shot", "Blind", "Paralysis", "Gouge"}
local Spells2 = {"Silence", "Counterspell", "Silencing Shot", "Strangulate", "Garrote", "Solar Beam", "Spell Lock"}
local Spells3 = {"Intimidating Shout"}
local Spells4 = {"Kick", "Rebuke", "Wind Shear", "Pummel", "Mind Freeze", "Skull Bash"}
local Spells5 = {"Deep Freeze"}
local ShowInfo = true; -- Prints information about taken actions in Chatwindow
local Delay = 0.002; -- The Delay the Script waits for casting in seconds.
local SetStopCasting = true;

function ACCprint(msg)
if ShowInfo == true then print("|cFF00CCFFAntiCC: |r" .. msg); end
end

function IsCastingOrChanneling()
if UnitCastingInfo("player") or UnitChannelInfo("player") and SetStopCasting == true then return 1; end
end

local Timer, Reset, ACCSpell = 0, true;
local type, hideCaster, srcGUID, srcName, srcFlags, srcFlags2, dstGUID, dstName, spellName, spellSchool, missType;
function Queue()
if GetTime() >= Timer and Reset == false then
if GetSpellCooldown(ACCSpell) == 0 then
if IsCastingOrChanneling() == 1 then SpellStopCasting(); end
ACCprint("|cFFFF6060" .. srcName .. "|r" .. " hits you with " .. "|cFFFFFF00" .. spellName .. "|r" .. ". Trying to cast " .. ACCSpell .. "...");
else
ACCprint("|cFFFF6060" .. srcName .. "|r" .. " hits you with " .. "|cFFFFFF00" .. spellName .. "|r" .. ". Unfortunately " .. ACCSpell .. " is on Cooldown. ");
end
CCSrc = GetObjectFromGUID(srcGUID);
CCSrc:CastSpellByName(ACCSpell);
Reset = true;
end
end
SetTimerCallback (Queue, 1);

local frame = CreateFrame("FRAME", "AntiCC");
frame:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED");
local function eventHandler(self, event, ...)
type, hideCaster, srcGUID, srcName, srcFlags, srcFlags2, dstGUID, dstName = select(2, ...); -- Read Combat Log
if type == "SPELL_CAST_SUCCESS" then
