What are the ()s and selfs for?

How would I add:

('save stage area to sprite' #- #grabFromScreen)

In the coding box put:

Code:

grabScreen
grabFromScreen.

I think this should work.

So, is this what it should look like?

blah         -
grabScreen
grabFromScreen.

?

Nothing happens. Nothing much happens when I make any block...

Glitch?

Ahh...
This might be it:
add
^ self
at the end of the code

I need a new block urgently!!!!

I need a block that will convert number to character, like 1=A, 2=B e.t.c and an option to report it uppercase or lowercase! It has to be a reporter.

I can't think how to do it!

I've just accidentally got us a lot of publicity. Skystar did a request of a Panther for our site, and her projects always get A LOT of hits, so our view ratings for the site are gonna shoot up, and we're gonna get a lot of people interested 

Nice ... XD

Where is nXIII? This is the least active I have ever known him to be.

oh poor you mp. er, he's away, gets back this evening. thing is, evening for him is early morning for me, and I have a physics assesment tomorrow so I won't see what's he has to say till the afternoon :'( hols are over.

I think something's messed up with my version of 1.2... None of my created blocks work...

What's your code?

self is the receiver of whatever message you are sending (the function). Just putting the message wouldn't work, it would say 'message not understood'. The ()'s are to help with layout, because if you put
self pointToX: self getVar: 'blah' y: 0.
it wouldn't work because 'pointToX:getVar:y:' isn't a message, whereas with
self pointToX: (self getVar: 'blah') y: 0.
the messages are 'pointToX:y:' and 'getVar:'.

@Sep:
You aren't defining a new message (well, you're defining doIt and doitIn:, but let's not get into evaluations and contexts), so don't put the message name at the top. For example, your 'grab patch from screen' block would look like this:
___________________________________
grab from screen                |  -       |
-----------------------------------------------------
grabFromScreen.
^ self (optional, automatically included)

@someone
I don't think it's necessary to add the variable/list exists blocks, please give me a couple scenarios in which this cannot be accomplished with a few other blocks.

Just so people know, I am removing the dev menus and the shift-click file menus from the final public version and making the source available elsewhere. This helps prevent people just hacking and not giving proper credit to the Panther developers in their derivative works.

You should ask this guy to be on your team for panther: http://scratch.mit.edu/forums/viewtopic.php?id=34152

He looks like he knows what he's doing.
