In this guide, you will learn to use Gossip Menus correctly. I will be using the WarpNPC LUA script as my example. You will need to read my guide on Basic LUA before you move on to this guide, as I call it, my LUA 1.5 guide before the advanced guide is released.
Prerisque: [Only registered and activated users can see links. ]

This guide is currently being revamped - meaning its being rewritten in a better format. I will be doing guards in LUA as my example.

Ok, lets get started!

First, your going to need the patch for this. I recommend that you do not use it as it does not work with the latest OpenAscent or Ascent revisions. I would simply recommend that you use LUA++'s LUA folder, which has all these cool LUA patches applied. For those of you who can compile, here is their SVN address: [Only registered and activated users can see links. ]. For those of you who can't, here is it in .ZIP format: [Only registered and activated users can see links. ]. Simply replace this LUAScripting folder with the current one.

Second, we need to look at the commands that are included that we will need to create our Gossip Menu.
Here they are:
:GossipCreateMenu
:GossipMenuAddItem
:GossipSendMenu
:GossipComplete
:GossipSendPOI


Second, it is time to start our script off with the usual "function" line.
Example:

function On_Gossip (pUnit, event, player)

Third, we must create our Gossip Menu.

pUnit:GossipCreateMenu(100, player)

Next, it is time to add the actual menus and lines.

pUnit:GossipMenuAddItem(player, 0, "Horde Cities", 1, 0)
pUnit:GossipMenuAddItem(player, 0, "Alliance Cities", 2, 0)

Third, Make sure that you are labeling the "" part with the Menu's name and then the number following that, the number of the menu.

Fourth, we need to send the menu with the function :GossipSendMenu.

pUnit::GossipSendMenu(player)

Fifth, we need to end that function. So it should look something like this:

function On_Gossip (pUnit, event, player)
pUnit:GossipCreateMenu(100, player)
pUnit:GossipMenuAddItem(player, 0, "Horde Cities", 1, 0)
pUnit:GossipMenuAddItem(player, 0, "Alliance Cities", 2, 0)
pUnit:GossipSendMenu(player)
end

Now to start on the submenus! Start it off with function line:

function Gossip_Submenus (pUnit, event, player, id, intid, code)

Sixth, we need to declare that we are using the menu 1, or "Horde Cities". We will do this by using this statement:

if(intid == 1) then

This says that if the menu number is 1, then we will recall the following until we hit the "end" statement.

Now, we need to add our submenus for "Horde Cities". We also need to add the :GossipSendMenu to the bottom.

pUnit:GossipGossipMenuAddItem(99, player)
pUnit:GossipMenuAddItem(player, 5, "Orgrimmar", 10, 0)
pUnit:GossipMenuAddItem(player, 5, "Undercity", 11, 0)
pUnit:GossipMenuAddItem(player, 5, "Thunder Bluff", 12, 0)
pUnit:GossipMenuAddItem(player, 5, "Silvermoon", 13, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:GossipSendMenu

Take note that the 99 is 1 number less than the 100 we used in the first function. This is consistant for all submenus. Now add the "end" statement to the end of that group of Menus and you should have something like this:

function On_Gossip (pUnit, event, player)
pUnit:GossipCreateMenu(100, player)
pUnit:GossipGossipMenuAddItem(player, 0, "Horde Cities", 1, 0)
pUnit:GossipGossipMenuAddItem(player, 0, "Alliance Cities", 2, 0)
pUnit:GossipSendMenu(player)
end
function Gossip_Submenus (pUnit, event, player, id, intid, code)
if(intid == 1) then
pUnit:GossipGossipMenuAddItem(99, player)
pUnit:GossipMenuAddItem(player, 5, "Orgrimmar", 10, 0)
pUnit:GossipMenuAddItem(player, 5, "Undercity", 11, 0)
pUnit:GossipMenuAddItem(player, 5, "Thunder Bluff", 12, 0)
pUnit:GossipMenuAddItem(player, 5, "Silvermoon", 13, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:GossipSendMenu(player)
end

Seventh, its time to do the submenu for the number 2, or "Alliance Cities". We have to use the "if" statement again to recall this menu.

if(intid == 2) then

Now guess what? Thats right, we have to add the submenus.
So repeat the steps from step six, exept this time we need to change the numbers after the Menu name because they will be recalled later. It should look something like this:

pUnit:GossipCreateMenu(99, player)
pUnit:GossipMenuAddItem(player, 5, "Stormwind", 14, 0)
pUnit:GossipMenuAddItem(player, 5, "Ironforge", 15, 0)
pUnit:GossipMenuAddItem(player, 5, "Darnassus", 16, 0)
pUnit:GossipMenuAddItem(player, 5, "Exodar", 17, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:MenuSendToPlayer(player)
end

Eighth, we need to add the locations for the teleporting. Use this format and simply repeat. After the == signs, add the number after the submenu name for the teleportion. Of course the format is (Map, X, Y, Z).

if(intid == 10) then
player:Teleport(1, 1371.068970, -4370.801758, 26.052483)
end

Now just repeat this until your done adding all the submenu's teleport locations.

Then you should add this line at the end of all your teleports:

intid = 0
end

Finally, register the events:

RegisterGossipEvent(32000 , 1, "On_Gossip")(32000 , 2,"Gossip_Submenus")

For 32000, you simply put the NPC ID. You will then need to create an NPC with the flags set to gossip flags, or 1.

Here is my TeleportNPC:

I hope this guide helped you and will keep you busy until my LUA: For Advanced Users guide is released. I will, in the meantime, be doing some XML and LUA tutorials related to WoW addons. So if you wanna check those out feel free.

Would you mind going into detail about what each part does, like in your first tut, and have lists of available options etc. Otherwise, great guide

[Creepfold]

SectorSeven, you are realy good in LUA it seems like this script, can i talk to you through MSN? you need to learn me some stuff and i want to ask you some stuff to
I wish to get more advanced with LUA's
add me : [Only registered and activated users can see links. ]


EDIT : i made a small version of this myself, i dont know if it works or not but :

 function WarpNPC_On_Gossip (pUnit, event, player)
pUnit:GossipCreateMenu(100, player)
pUnit:GossipMenuAddItem(player, 0, "Horde Locations", 1, 0)
pUnit:GossipMenuAddItem(player, 0, "Alliance Locations", 2, 0)
pUnit:GossipSendMenu(player)
end

function WarpNPC_Submenus (pUnit, event, player, id, intid, code)
if(intid == 1) then
pUnit:GossipGossipMenuAddItem(99, player)
pUnit:GossipMenuAddItem(player, 5, "Mall", 10, 0)
pUnit:GossipMenuAddItem(player, 5, "Leveling Road", 11, 0)
pUnit:GossipMenuAddItem(player, 5, "Custom Instances", 12, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:GossipSendMenu(player)
end

if(intid == 2) then
pUnit:GossipCreateMenu(99, player)
pUnit:GossipMenuAddItem(player, 5, "Mall", 10, 0)
pUnit:GossipMenuAddItem(player, 5, "Leveling Road", 11, 0)
pUnit:GossipMenuAddItem(player, 5, "Custom Instances", 12, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:MenuSendToPlayer(player)
end

if(intid == 10) then
player:Teleport(1, -1657.646973, 3096.333008, 32.558029)
end

if(intid == 11) then
player:Teleport(580, 1713.559937, 600.632690, 29.677027)
end

function WarpNPC_Submenus2 (pUnit, event, player, id, intid, code)
if(intid == 12) then
pUnit:GossipCreateMenu(99, player)
pUnit:GossipMenuAddItem(player, 5, "Malygos' Lair(10-15Man)", 13, 0)
pUnit:GossipMenuAddItem(player, 5, "Scarlet Monastery(5-10Man)", 14, 0)
pUnit:GossipMenuAddItem(player, 5, "The Deadmines(10Man)", 15, 0)
pUnit:GossipMenuAddItem(player, 5, "[Back]", 50, 0)
pUnit:GossipSendMenu(player)
end

if(intid == 13) then
player:Teleport(530, 3099.646729, 1513.975342, 192.195267)
end

if(intid == 14) then
player:Teleport(0, 2888.867188, -810.674438, 162.649765)
end

if(intid == 15) then
player:Teleport(0, -11211.107422, 1661.814087, 26.746098)
end

RegisterGossipEvent(32000 , 1, "WarpNPC_On_Gossip")(32000 , 2,"WarpNPC_Submenus")(32000 , 2,"WarpNPC_Submenus2")

Should this work or? and also is there any way to test the LUA's on if they work or not without hosting an actual server?

[SectorSeven]

I'll look at it later.
Added to MSN.
Sorry its exam week so im studying alot!

[mager1794]

Hey SectorSeven i'd love to speak to you a bit to help me learn a bit more LUA im pretty advanced at it but theres alot you can teach me i believe (also i wanna ask something about ABD)

[Only registered and activated users can see links. ]

i dont have MSN messenger on this comp and my other one is broke ok dude but i'll get on this one soon : )

+rep btw nice guide

[pachuco55]

Right before you begin your if statements, you have a function. Wouldn't you need two end's in order to close both the last if statement and then the function?

btw +rep

[SectorSeven]

True that. My mistake...it was 3 in the morning

[degoscar]

Orgrimmar 1 1484 -4417 25

Undercity 0 1831 238 60

Thunder Bluff 1 -1277 118 131

Silvermoon 530 9413 -7277 14



Stormwind 0 -8951 524 96

Ironforge 0 -4981 -881 501

Exodar 530 -3826 -11686 -107

Darnassus 1 9948 2413 1327


In case anyone cares to have the loc's here they are.

[Only registered and activated users can see links. ]. Simply replace this LUAScripting folder with the current one.

I cant find a folder called LUAScripting. how do i do it?

[SectorSeven]

You have to compile your own ascent.

[pachuco55]

Third, we must create our Gossip Menu.

pUnit:GossipCreateMenu(100, player)

Will the first number always be 100? What does it represent?

[SectorSeven]

No, but the numbers after it (99 in this case) has to be 1 lower

[pachuco55]

Since I am only having one menu button in my menu, then I wouldn't need to worry about that, correct?

Also, does there need to be an OnGossipTalk function? I don't remember where I learned that but I think it was from another warp npc code.

[imsosorrygms]

Sector... When i try to replace the luascripting folder and then compile the scripts i get alot of errors... could u help me?
