Just got back into Lua and I have a problem...

[tyeeeee1]

Hey,

As the title says I just got back into scripting Lua after about a year. I started off with a basic gossip NPC but it doesn't seem to be working, if someone could check over the script below and tell me what I've done wrong that would help.
What is happening is that when I span and right click on the NPC in-game all I get is the usual "hello $N" message, there are no buttons or that in the menu.

local NPCID = 99999

function On_Gossip(Unit, event, player)
Unit:GossipCreateMenu(1, player, 0)
Unit:GossipMenuAddItem(0, "Screw you Oxhorn.", 1, 0)
Unit:GossipSendMenu(player)
end

function SubMenu_Gossip(Unit, event, player, id, intid, code)
if (intid == 1) then
Unit:SendChatMessage(12, 7, "**** off buddy, you don't want to fight with me.")
Unit:GossipComplete()
end
end

RegisterUnitGossipEvent(99999, 1, "On_Gossip")
RegisterUnitGossipEvent(99999, 2, "SubMenu_Gossip")

The NPCs entry ID is 99999 and I did select gossip when creating him on WoW-V.


WhyDB rev.157 changeset.107
Arcemu rev is in the latest as of yesterday
(I compiled my own server for once =) )

The script looks fine.

The issue here is a small bug with Lua: You can't have only one menu item.

If you change it to:

function testOn_Gossip(Unit, event, player)
	Unit:GossipCreateMenu(1, player, 0)
	Unit:GossipMenuAddItem(0, "Screw you Oxhorn.", 1, 0)
	Unit:GossipMenuAddItem(0, "Nevermind.", 2, 0)
	Unit:GossipSendMenu(player)
end

function testSubMenu_Gossip(Unit, event, player, id, intid, code)
	if (intid == 1) then
		Unit:SendChatMessage(12, 7, "**** off buddy, you don't want to fight with me.")
	end
	Unit:GossipComplete()
end

RegisterUnitGossipEvent(99999, 1, "testOn_Gossip")
RegisterUnitGossipEvent(99999, 2, "testSubMenu_Gossip")

It should work

Using:

function testOn_Gossip(Unit, event, player)
	Unit:GossipCreateMenu(1, player, 0)
	Unit:GossipMenuAddItem(0, "Screw you Oxhorn.", 1, 0)
	if (not Unit) then
		Unit:GossipMenuAddItem(0, "[DEBUG BUTTON - WILL NOT SHOW]", 2, 0)
	end
	Unit:GossipSendMenu(player)
end

Sometimes works at displaying only one button, since the other button condition is never met but the code is loaded.

Hmm, I think it might be a problem with the NPC now. I just changed my script and re-started the server (reloadscripts wont work =/ ) and he still says "Hey there, $N. How can I help you?

local NPCID = 99999

function On_Gossip(Unit, event, player)
Unit:GossipCreateMenu(1, player, 0)
Unit:GossipMenuAddItem(0, "Screw you Oxhorn.", 1, 0)
Unit:GossipMenuAddItem(0, "Nevermind.", 2, 0)
Unit:GossipSendMenu(player)
end

function SubMenu_Gossip(Unit, event, player, id, intid, code)
	if (intid == 1) then
		Unit:SendChatMessage(12, 7, "**** off buddy, you don't want to fight with me.")
	end
	Unit:GossipComplete()
end

RegisterUnitGossipEvent(99999, 1, "On_Gossip")
RegisterUnitGossipEvent(99999, 2, "SubMenu_Gossip")

Would it be possible that Lua was disabled/not-installed on my server? When I first went to create a script I manually created the scripts folder in my ArcEmu folder. I'm thinking that maybe I messed up somewhere in the compiling process.

You need to have the LuaEngine project enabled and then to make sure you copy it over into the correct folder.

Cmake -> enable LuaEngine project.
ArcEmu project -> compile -> run 'install' project.
Run contents of output folder -> should display "X Lua scripts loaded" in console when it nears the end of server start up.

Looks like Lua isnt being loaded as far as my world.exe says. I'll do a re-compile and see where that gets me.
I'll report back in a few hours.

Well its all fixed now... I'll just say it was all human error.
