So i have a function like that:

function PVPSound_UpdateSoundEffectEngine(self, elapsed)

end

PVPSoundEffectSoundEngineFrame:SetScript("OnUpdate", PVPSound_UpdateSoundEffectEngine)

If i change the function to:

local addon, ns = ...
local PVPSound = { }
ns.PVPSound = PVPSound

function PVPSound:UpdateSoundEffectEngine(self, elapsed)

end

PVPSoundEffectSoundEngineFrame:SetScript("OnUpdate", PVPSound:UpdateSoundEffectEngine)

Then why cant i make the function local?
Also why cant call the function like that with the SetScript?
