OnEvent event is nil

Post by Kex0 » Wed May 24, 2023 5:57 pm

Here's code example:

Code: Select all

local f = CreateFrame('Frame')
f:RegisterEvent('CHAT_MSG_TEXT_EMOTE')
f:SetScript('OnEvent', function(self, event, msg, player)
    print(event)
    if event == "CHAT_MSG_TEXT_EMOTE" then
        if msg:find('cry') then
            print("crying "..player)
        end
    end
end)
I'm trying to make a simple addon and I want to use events. The problem is that
`event` within `f:SetScript('OnEvent', function(self, event, msg, player)` is always `nil`. As a matter of fact all arguments are always `nil`. The only way I can get past `if event == "CHAT_MSG_TEXT_EMOTE" then` is with this code:

Code: Select all

local f = CreateFrame('Frame')
f:RegisterEvent('CHAT_MSG_TEXT_EMOTE')
f:SetScript('OnEvent', function()
    print(event)
    if event == "CHAT_MSG_TEXT_EMOTE" then
        if msg:find('cry') then
            print("crying "..player)
        end
    end
end)
but then I have no other arguments like `msg` or `player` from `CHAT_MSG_TEXT_EMOTE`

What am I doing wrong? This happens with every event.

You almost got it. Event arguments are supplied as the variables arg1, arg2 etc. See the documentation here: https://wowwiki-archive.fandom.com/wiki ... TEXT_EMOTE

Try the following code instead:

Code: Select all

local f = CreateFrame('Frame')
f:RegisterEvent('CHAT_MSG_TEXT_EMOTE')
f:SetScript('OnEvent', function()
    print(event)
    if event == "CHAT_MSG_TEXT_EMOTE" then
        if string.find(arg1,'cry') then
            print("crying "..arg2)
        end
    end
end)

Thank you very much!
I was reading just this https://wowpedia.fandom.com/wiki/CHAT_MSG_TEXT_EMOTE
and it has no mention of arg1, arg2, ...

thank you very much for posting this about the arg1 arg2 variable names and pointing to the fandom.com wiki pages for reference. I couldn't get this figured out for hours
