Help with trinitycore Eluna script

[spleee101]

So i feel really stupid having to ask this question, but I have not done lua before and for the life of me can not figure out this error I am getting. The script is literally a direct copy of the basic tutorial script from emudevs youtube video and is below,

local npcId = 555008

function OnEnterCombat(event, creature, target)
    creature:CastSpell(target, 2000, true)
end

function OnLeaveCombat(event, creature)
    creature:SendUnitSay("text blah blah", 0)
end
    
RegisterCreatureEvent(npcId, 1, OnEnterCombat)
RegisterCreatureEvent(npcId, 2, OnLeaveCombat) 

the error i get is

lua: prog.lua:11: attempt to call global 'RegisterCreatureEvent' (a nil value)
stack traceback:
    prog.lua:11: in main chunk
    [C]: in ?

EDIT: Solved no longer an issue....

It looks like this was an issue with the emulator you were using, not the script. Probably a bad repack.

Line 11 RegisterCreatureEvent was not understood. This means it wasn't in the API.

hey thanks for responding stone harry I appreciate it. However this is from a compiled eluna source no repacks can be found near my computer :P. the mistake was actually a typo in my OnEnterCombat function. All in all i got it working and all is good, thanks for helping me out like always tho appreciate it man.
