Detect vendor window problems

[zachwlewis]

After days of reading, I've decided to work on my first WOW AddOn. I'm trying to create one to prompt the user when she opens a vendor window and the vendor sells a recipe they can learn but do not already know.

As of right now, I've got the NewRecipe.toc, NewRecipe.xml and NewRecipe.lua.

My XML looks something like this:

<Ui xmlns="http://www.blizzard.com/wow/ui/"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.blizzard.com/wow/ui/ ..\FrameXML\UI.xsd">

<Script file="NewRecipe.lua" />

<Frame name="NewRecipe_core">
  <Scripts>
    <OnLoad>
      this:RegisterEvent("VARIABLES_LOADED");
    </OnLoad>
    <OnEvent>
      if(event=="VARIABLES_LOADED")then
        NewRecipe_init();
      elseif(event=="MERCHANT_SHOW")then
        NewRecipe_popup();
      end;
    </OnEvent>
  </Scripts>
</Frame>

</Ui>

My Lua looks something like this:

function NewRecipe_init()
  SendChatMessage("Loaded.", "SAY");
end;

function NewRecipe_popup()
  SendChatMessage("Popup.", "SAY");
end;

If I call "/console reloadui," I see the message displayed by NewRecipe_init(); however, when I talk to a vendor, the function doesn't fire.

I know that those SendChatMessage functions probably aren't the best thing to use, but I'm just trying to detect an event fire.

Any suggestions?

Your frame "NewRecipe_core" has only been registered to receive the "VARIABLES_LOADED" event. If you want the "MERCHANT_SHOW" event, you need to insert
this:RegisterEvent("MERCHANT_SHOW");


if you want a simple output for testing, I suggest declaring a function such as:

function Print(x)
	DEFAULT_CHAT_FRAME:AddMessage(x)
end

in your lua code. Then use Print("Message")
