Get selected gossip index

[bublix]

Hey there,

I'm trying to find out how to get the selected gossip index.

If you talk to a Stormwind City Guard you can choose serveral options like "Auction House", "Bank of Stromwind", "Stormwind Harbor", ...

If I click on on of these items, the event "GOSSIP_CONFIRM_CANCLE" will be thrown. The problem is: The event has no parameters....

Is it possible to get the selected index?

Thanks in advance,
bublix

You can either hook the SelectGossip function, or hook the buttons' OnClick scripts. What are you actually trying to achieve, functionality-wise?

Thanks for the quick reply. I'm trying to get the Index to send it to another character, that he can use it with "SelectGossipOption(index)".

Unfortunately I don't know wehre the function "SelectGossip()" is stored.

There are 3 different functions depending on the type of gossip dialog from the npc: SelectGossipActiveQuest, SelectGossipAvailableQuest, and SelectGossipOption.

It sounds like you're probably interested in the SelectGossipOption function, so to hook it all you need to do is something like this..

hooksecurefunc('SelectGossipOption', print)

or

hooksecurefunc('SelectGossipOption', function(index, text, confirm)
    print('Gossip index selected:', index)
end)

Well, thats basically it.

I had never expected, that it's so simple.

Thanks to you guys!

Edit:
Here is another solution.
(I need to do stuff before the hooked function)

function New_SelectGossipOption(index, text, confirm)
    print('Before')
    Old_SelectGossipOption(index, text, confirm)
    print('After')
end
 
Old_SelectGossipOption = SelectGossipOption
SelectGossipOption = New_SelectGossipOption

I know it looks like a great idea to override SelectGossipOption

But in the long run this could cause taint so bad that you break UI functionality, that's the worst case.

Instead you should use hooksecurefunc or hook widget objects like with HookScript and do something after certain functions are called, or if you want to change the behavior you should change the behavior by editing the (in this case) Gossip Frame instead of affecting all elements utilizing SelectGossipOption.

Anyway semlar had good examples how to just read what options were picked by the user, without breaking anything. This way you can read what index was selected, then do what ever you wanna do with it.

If you HAVE to pre-hook it, I would attempt to hook the gossip button's preclick event first because overwriting the blizzard function is going to cause taint which will probably have consequences (like breaking buttons in the interface).
