Who is "me" in this line?

[standgale]

I have the following line

Code: Select all

   put "" into field "tableDiscrep" of card "cardCalculate" of me

But it can't find the card.
So I was wondering - who is "me" here?

This line is in a stack-only script which is a behaviour of the main stack. The main stack has a card by this name.
This Livecode wiki page https://livecode.fandom.com/wiki/Me says

If me is executed in a behavior script, then me refers to the object that is executing the behavior script.

So I would have thought that the stack is "me" but it seems not. Is the behaviour "me"?

Oh yeah, this line is in a handler, which is called from another handler within the same script - but that handler is called from another script in another stack. In fact, it is being called from the behaviour script of cardCalculate, the card that can't be found.

It does seem to work if I specify the stack name rather than use "me", but I'd like to know who "me" is in here.

Thanks.

Hi, standgale.
You could insert code like this:

Code: Select all

answer the long name of me

You could replace “me” with “this stack” - that’s still abstracted so can be used with any stack. Not tested though, as am travelling abroad…

Yes, ME is the stack that this behavior is attached to!

Is it really?
I thought me referenced the specific object calling the script.
A behavior script runs "instanced" to resolve all references relative to the calling object as if it were the "longhand" script of that object.
So "me" could/should resolve to the card name in the substack I think. Is it trying to refer to a card "of a card" rather than a stack?

[Klaus]

Well, "... of cd xyz of me" really makes me think this is a stack, what else has cards?

[SparkOut]

Yes but what happens if the script resolves "me" to "card xyx of stack xyz" and means the script tries to do something with field "abc" of card "abd" of card "xyx" of stack "xyz"?

Dick's suggestion to answer the long name of me within that script is a good one.

thanks for that advice. Can't believe I forgot to do that simple thing!

I tried it and when I run the program in the IDE then "me" is my main stack like its supposed to be, but when I try to "save as a standalone application" it pops the message box as well, and "me" is now the behaviour script the code is physically located in.
