    if plr ~= nil then
    Unit:SendChatMessage(14(yell),0(Universal lang),plr:GetName()..", you cannot resist me!")

    function CastSpell(Unit,event)
    Unit:CastSpell(5) -- death touch xd

    :CastSpellOnTarget(spellid,target) -- first argument is spellid just like above, 2nd is target, there is a bug w/ this function that it causes it not to cast on the target.

    Use FullCastSpellOnTarget(spellid,target) if you want to cast on a target.

    :SpawnCreature(entryid,x,y,z,faction,duration) -- Unlike spawngameobject, creatures use factions. This decides whether they are friendly/hated towards the player and other stuff like if you kill it what rep u get.

    Unit:SpawnCreature(randomnumberhere,Unit:GetX(),Un it:GetY(),Unit:GetZ(),14,5000(despawn after 5 secs))

    Unit:FullCastSpellOnTarget(5,Unit:GetRandomPlayer( 0))

    :RemoveEvents() -- this has no arguments and removes all registered functions.

    function OnCreatureDied(Unit,event)
    Unit:RemoveEvents()-- when the creature is dead, remove all functions so it doesn't do anything.

    :SendBroadcastMessage(string) -- this is a player only command. The player who called it, displays a message that you typed in there

    function Error(Unit,event)
    local tank = Unit:GetMainTank()
    tank:SendBroadCastMessage("You are now tanking "..Unit:GetName())

    :SendAreaTriggerMessage(stringfunc) - This sends a message across the top center of your screen. Similar like a raid warning message.
    :KnockBack() -- neither this.
    :MarkQuestObjectiveAsComplete(questid,objective) -- Never used this.

    local plr = Unit:GetClosestPlayer()
    plr:UnlearnSpell(5) -- noooes gief death touch!!

    :HasFinishedQuest(questid)-- this is a boolean like others to come. It checks whether the player has finished the quest provided w/ the id, if not, it pushes false.

    local plr = Unit:GetClosestPlayer()
    if plr:HasFinishedQuest(questid) == true then
    do this if the player has completed the quest

    :CreateWaypoint(x,y,z,waittime,moveflags,displayid ) -- x,y,z are the coords, waittime is the delay for it to not move,moveflags are either 0 for walk, 256 for run, or 768 for fly, displayid is how you want the waypoints to look like(Like mini models).
    :*DestroyCustomWaypointMap() -- use it to destroy all waypoints that the unit has. Only works for creatures.
    :MoveToWaypoint(waypointid) -- When you create ur first waypoint, they are numberd in order start from 1. 0 and 1 do the same thing. Use it to make a unit move to various waypoints.
    :TeleportUnit(mapid,x,y,z) -- This teleport's a PLAYER only unit to the location specified.

    Unit:ChannelSpell(plr:GetGUID(),spellid) -- channel a certain spell on the player.

    :ReturnToSpawnPoint() -- makes a unit go back to its spawn point.
    :HasAura(auraid) -- this is a boolean, returns true if the unit has the auraid given, or false if not.

    :Strike(target,dmg,sp,adddmg,exclusivedmg,pct_dmg_ mod) -- I dono xD
    :Kill(target) -- this pretty much calls a dealdamage that deals damage equivalent to the Units hp.
