I'm currently using Sublime Text to edit my SCAR code, but I am unable to get the Print() function to return the values I am trying to track. Does anyone have any idea on how to get this set up? Would make debugging so much easier.

For some reason CoH2 does not output calls to print to a scarlog as CoH1 did. This is what I wrote for use in my own mods:

    

    _G.print = {

        cache = ''

    }



    setmetatable(_G.print, {

        __call = function(self, ...)

            local args = {...}

            for index = 1, #args do

                self.cache = self.cache..tostring(args[index])..'\t'

            end

            self.cache = self.cache..'\n'

            PersistentMode_SerializeResults('userdata:logs/scarlog.txt', self.cache)

        end

    })

Feel free to use it.

No, it's Lua. This was neither helpful nor correct. The function is print.

How do you implement the code you provided? I've placed it in my .scar file but I get the following error:

Code

GameObj::OnFatalScarError: [[string "DATA:Scenarios\city_centre_2.scar"]:23: attempt to call global 'PersistentMode_SerializeResults' (a nil value)]

Also, do I still use print() in order to see the result?

Thanks!

That means SCAR has not yet initialized. So, as a general rule of thumb, you want all of your code to start after that has happened.

For example:

Scar_AddInit(function()

    -- put code here

end)

This is also mentioned in the SCAR documentation:

When the game engine reads your *.scar file, anything in the global scope will be immediately called. This may cause problems as some functions are not meant to be used until the game has loaded up all of its components.

The function Scar_AddInit( FunctionName ) can be used to kick off your script. This tells the game engine "When you are ready, call the function FunctionName first."

And yes, you would just call print, like so: print('hello world') or print('hello', 'world')

It takes n arguments.
