Double Events

[Zinc]

Alright, I`m no stranger to coding, but I`m a bit new to WoW API Lua. So, for my first challenge, I`m making a chat bot. So, I decided to make it have a welcoming message. This is what I had so far.

  local frame = CreateFrame("FRAME", "MParent");
  frame:RegisterEvent("CHAT_MSG_CHANNEL_JOIN");

  local function autoResponse()
    print("|CFF00FF00Someone has entered the channel.|R");
  end

  frame:SetScript("OnEvent",autoResponse);

However, it is firing the event twice each time someone joins the channel, so it says:

Someone has entered the channel. Someone has entered the channel.

Have you tried dumping out the arguments from the event?

You could either add some code to your existing addon to do this, or you might like to use the eventtrace tool (/eventtrace).

No idea how to do that.

How do you load your posted code ?
I've seen cases where it was loaded twice resulting in double events.
Is it loaded in the toc and in a xml ?

.xml

<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="HelloWorld.lua"/>
  <Frame name="MParent">
  </Frame>

</Ui>

.lua

  local frame = CreateFrame("FRAME", "MParent");
  frame:RegisterEvent("CHAT_MSG_CHANNEL_JOIN");

  local function autoResponse()
    print("|CFF00FF00Someone has entered the channel.|R");
  end

  frame:SetScript("OnEvent",autoResponse);

.toc

## Interface: 30100
## Title: Hello World!
## Notes: All Purpose
## Dependencies: 
HelloWorld.lua
HelloWorld.xml

As you can see, I just modify one AddOn to serve as all my AddOns.

You're loading HelloWorld.lua twice, once in the .toc and once in the .xml. Ergo, you get double messages.
