[Help!] Scripting a GO object with LUA???

[pioneer1337]

Well I saw a guide on how to script a game object to teleport you somewhere (Portal...) and I wa swondering if it would be possible to script it to do other things liek cast a spell on you...?
Here's the script I wrote and I was wondering why it wont work:

function Cannon_onUse (pUnit, Event, pMisc)
print "Cannon launched!"
pMisc:CastSpell (42867);
end
RegisterGameObjectEvent (186560, 2, "Cannon_onUse")

It says "Cannon launched!" in the arcemu-world.exe window so I know it half-works but it just wont cast the spell on the player...

Give this a try, havent tested but may work.

function Cannon_onUse (pUnit, Event, pMisc)
print "Cannon launched!"
pUnit:CastSpell (42867);
end
RegisterGameObjectEvent (186560, 2, "Cannon_onUse")

you have to make it select a target and then CastSpellOnTarget
like this

function Cannon_onUse (pUnit, Event, pMisc)
print "Cannon launched!"
pUnit:CastSpellOnTarget(42867, pUnit:GetClosestPlayer());
end
RegisterGameObjectEvent (186560, 2, "Cannon_onUse")

function Cannon_onUse (pUnit, Event, pMisc)
print "Cannon launched!"
pUnit:CastSpell (42867);
end
RegisterGameObjectEvent (186560, 2, "Cannon_onUse")

Hmmm... I got different results with that.. now in the arcemu-world.exe window it says: "...attempt to call method 'CastSpell' <a nil value>".
