I'd like to preface my question with the information that I'm new to writing in LUA. With that out of the way....

I'm having a problem with an addon that I'm working on where I can't seem to get one method to call another method. For example, this works:

function MyAddon:StartSomething()
  DoSomething(something);
end

function DoSomething(something)
  --Stuff goes here
end

But this does not:

function MyAddon:StartSomething()
  MyAddon:DoSomething(something);
end

function MyAddon:DoSomething(something)
  --Stuff goes here
end

I get an error message "Attempt to call method 'DoSomething' (a nil value)" and I just don't really understand what's going on. I've also tried calling "self:DoSomething(something)" and get the same result. Any help would be greatly appreciated.

try this, it's more fun.

local function StartSomething()
BustAMove();
end

local function BustAMove()
CombatText_AddMessage("BOO", COMBAT_TEXT_SCROLL_FUNCTION, 0*255, 0.8*255, 1*255)
end

As for your issue, I think it has to do with how you call the function. In the first example (the working one), you call the function from - I assume - a frame or button. That function calls a second function. It works.

In the 2nd example, you call a function from a frame, which then calls another function which is part of that frame. I think that MyAddon:DoSomething() has issues with the parenting in the second example. But I can easily be wrong.

Looking at the exact code rather than representation does a lot as it provides context.

MyAddon:FunctionName() and self:FunctionName() are basically the same thing where self = MyAddon (the value of self can be different depending on the context)

The only thing I can suggest w/o seeing your actual code is: make sure you spell the function the same way in both places (DoSomething ~= Dosomething ~= DoSomehting). When I get into WTF headscratchers like that I generally copy/paste the function name so I make damn sure it's all the same.

Where are you actually calling :StartSomething() e.g.

local MyAddon = {}
function MyAddon:StartSomething()
  MyAddon:DoSomething(something);
end

MyAddon:StartSomething()

function MyAddon:DoSomething(something)
  print("Doing Something")
end

Will give you this error

lua: test2.lua:24: attempt to call method 'DoSomething' (a nil value)

whereas

local MyAddon = {}
function MyAddon:StartSomething()
  MyAddon:DoSomething(something);
end

function MyAddon:DoSomething(something)
  print("Doing Something")
end
MyAddon:StartSomething()

Will work fine and dandy.

I agree with the above. For proper debugging, we need to see the whole thing or, at least, where you are calling :StartSomething().

P.S. The code you say doesn't work, works fine for me.
