I want to call a specific function when the slash command is executed...

But, I keep getting the following error:


Message: ..\AddOns\FayAfk\FayAfk.lua line 25:
attempt to call global 'SetAfk' (a nil value)


What am I doing wrong...


From my script:

FayAfk:RegisterChatCommand({ "/fayafk"}, {
		type = "execute", name = "cs", desc = "cs",
		func = SetAfk(),
	})

I'm not being lazy..

I've read all the examples. Many times.

I have downloaded mods and tried different stuff hundreds of times until my head felt like it was going to explode.

Don't Understand it? Yes.
Lazy? No.

Sorry, thought classroom was for when you didn't understand something.

:(

I found this tricky at first also by the way, but once it clicks it'll seem simple.

The value of func can be either a string, which is the name of the function to call, or an actual function that you define as the table entry itself.

You're actually trying to call a function, which by itself is neither. What you need to do is set "func" to be either the string "SetAfk", or an anonymous function that calls SetAfk() and pass whatever it returns.

You can define a function something like this:

function()
	somevar = 'arse'
	return somevar
end

So, here's what you need to do (I've split off the table that you're passing to :RegisterChatCommand() to try and make it more clear):

either:

local myopts = {
	type = 'execute',
	name = 'cs',
	desc = 'cs',
	func = function() return SetAfk() end,
	}

FayAfk:RegisterChatCommand({ '/fayafk' }, myopts)

or:

local myopts = {
	type = 'execute',
	name = 'cs',
	desc = 'cs',
	func = 'SetAfk',
	}

Hope that helps (and is correct!).

Ah! Thank you very much, Fin.

That helps a lot.

this is a 3-fold issue...

if your function is part of the addon object...

function Blah:Blorp() ...

then use "func = 'Blorp'" This ensures 'self' is passed correctly.

If you don't need any args passed, you can pass the function object, "func = Blah.Blorp"
or

local fump = function() ... end

"func = fump"

Or, if you need to ensure certain args are passed, "func = function() fump("blah", "smoo") end"
