[Lua] Error while injecting

[Nilrac]

Making a Lua script and I have ran into an error
Here it is

input:19: attempt to call global 'RegisterUnitGossipEvent' (a nil value)

Here is the part that is causing the error, I cant tell whats wrong with it

function Npc_OnGossip(pUnit, event, player)
pUnit:GossipCreateMenu(50, player, 0)
pUnit:GossipMenuAddItem(6, "Sometexthere", 1, 0)
pUnit:GossipMenuAddItem(6, "Sometexthere", 2, 0)
pUnit:GossipSendMenu(player)
end
function Npc_OnGossipSelect(pUnit, event, player, id, intid)
if (intid == 1) then
player:SendBroadcastMessage("Sometexthere")
pUnit:CastSpell(38627)
pUnit:GossipComplete(player)
end
if (intid == 2) then
pUnit:GossipComplete(player)
player:SendBroadcastMessage("Sometexthere")
end
end

RegisterUnitGossipEvent(npcid, 1, "Npc_OnGossip")
RegisterUnitGossipEvent(npcid, 2, "Npc_OnGossipSelect")

function Npc_OnGossip(pUnit, event,)

change it to

function Npc_OnGossip(pUnit, event)

Thanks for spotting that error, but it still gives me

"input:19: attempt to call global 'RegisterUnitGossipEvent' (a nil value)"

Even after fixing that

[Herleybob]

Try changing this:

function Npc_OnGossip(pUnit, event,)

to

function Npc_OnGossip(pUnit, event, player)

You need someone to send menu too.

Nope... same error message

The error is saying line 19 You have npcid, it doesn't know what that is. (Also it does actually saying trying to register it? 0_0). After filling that in or defining it, and if that doesn't work remove the npc_ before each event bit and try.

Hi,

If you need this sort of script, i made one and tested it on ArcEmu rev. 2310.

It's nearly the same, but maybe it works for you:

function NPC_OnGossip(Unit, Event, player)
Unit:GossipCreateMenu(100, player, 0)
Unit:GossipMenuAddItem(6, "CHOOSE 1", 1, 0)
Unit:GossipMenuAddItem(6, "CHOOSE 2", 2, 0)
Unit:GossipSendMenu(player)
end

function NPC_OnSelect(Unit, Event, player, MenuId, id, Code)
if (id == 1) then
player:SendBroadcastMessage("YOU CHOOSE 1")
Unit:CastSpell(38627)
Unit:GossipComplete(player)
end
if (id == 2) then
player:SendBroadcastMessage("YOU CHOOSE 2")
Unit:GossipComplete(player)
end
end

RegisterUnitGossipEvent(Yournpcid, 1, "NPC_OnGossip")
RegisterUnitGossipEvent(Yournpcid, 2, "NPC_OnSelect")

function On_Gossip(pUnit, event, player)
pUnit:GossipCreateMenu(50, player, 0)
pUnit:GossipMenuAddItem(6, "Sometexthere", 1, 0)
pUnit:GossipMenuAddItem(6, "Sometexthere", 2, 0)
pUnit:GossipSendMenu(player)
end
function On_GossipSelect(pUnit, event, player, id, intid)
if (intid == 1) then
player:SendBroadcastMessage("Sometexthere")
pUnit:CastSpell(38627)
pUnit:GossipComplete(player)
end
if (intid == 2) then
pUnit:GossipComplete(player)
player:SendBroadcastMessage("Sometexthere")
end
end

RegisterUnitGossipEvent(NPCID , 1, "On_Gossip")
RegisterUnitGossipEvent(NPCID , 2, "On_GossipSelect")

Try it now.. You don't need to have "Npc_OnGossip" it's supposed to be like this "On_Gossip".

Hope it works for you. Just remember to change "NPCID" to the same ID in your SQL script, which is your Entry ID. They need to be the same, else the SQL and LUA will not be able to co-work.
