Character map or just the Alt shortcuts?

char map

I figured I'd trim a few characters off    (I actually did change the code, if you're wondering)

seesBroadcast:n
    ScratchEvent allInstances do:[:e|e name=n ifTrue:[^true]].^ false

it works fine now, but you said to put this code in to someone
('%e received?' #b #seesBroadcast)

but i had to change it to this in order for it to work

('%e received?' #b #seesBroadcast: ' ')

I didn't say ('%e received?' #b #seesBroadcast) I said ('%e received?' #b #seesBroadcast: ' ')

Laddies and gentlemen, may I now present:
The <[] received?> Block!!!!!!!!!!!!!!!!!!!!!!!
First of all, I would like to tha...
SHUT UP AND TELL US THE CODE ALREADY!!!
OK, Ok.    Anyways, here is the (long-awaited) code:
[drumroll]

Code:

seesBroadcast: t1 
    | t2 |
    t2 _ ScratchEvent allInstances.
    t2
        reverseDo:     
            [:t3 | 
            t3 name = t1 ifTrue: [^ true].
            nil].
    ^ false

Unlike the Panther received block, this block picks up a broadcast wether there is a receive hat block for it or not.
[\b]

Note: The more broadcasts the project has, the less likely it is that the block will detect it. Also, the block probally will not work if it is a result of a sprite being clicked or a key being pressed. In other words, if you use this block, use
<when green flag clicked>
<forever if>[/blocks]<I receive []>
...do whatever here...

<end>
[/blocks] instead of
<when I receive[

Edit: If you are wondering how the heck there's so many views but so little posts, that's because I made a Panther ptoject to tell me when there's a new post. But that involved looking at the web page. Which made the views go up.
Also, this is NOT a forum thread to sugest hacked blocks. Just because I make one cool block does NOT make me a block dispenser.

THANKS!!!always wanted one. BTW i lost the game

BTW where do you put this code? Please tell me, thanks!

Shortly,

Instance:
1. Shift-click the R on the Scratch logo and hit "turn fill screen off".
2. Right-click the white space.
3. Hit "open", then "browser".
4. Hit "Scratch-Objects".
5. Hit "ScriptableScratchMorph".
6. Scroll to the bottom.
7. Right-click next to "private".
8. A menu will come up.  Hit "new category...".
9. Hit "new...".
10. Type in "new ops" and click "Accept (s)".
11. In a text box it says "message selector and argument names "comment stating purpose of message" |temporary variable names| statements".  Delete that, and insert the code for the block.
12. Right-click the text and click "accept (s)".
13. Hit the close button at the top-left.
14. Shift click the R in the Scratch logo and hit "turn fill screen on".

WAIT!  It doesn't show up!

I know it doesn't show up yet.  You're not done coding yet.

The next part, the class:
1. Do steps 1-4 of the instance instructions.
2. Hit "class" (next to instance and ?).
3. Hit "ScriptableScratchMorph".
4. Hit "block specs".
5. Hit "blockSpecs".
6. Hit down, twice.
7. Press the right arrow key 17 times.
8. Press space.
9. Type in ('%e received?' #b #seesBroadcast: ' ')
10. Right click in the box.
11. Hit "accept (s)".
12. Hit the close button in the top-left.
13. Shift click the R in the scratch logo and select "turn fill screen on".

Hope this helps.

How long do 'ScratchEvents' live for?

Until it is done being called.

So to make this work well, then use the [broadcast [] and wait] block.

where does this go in?

This code goes into instance, other ops and replace any code, with

seesBroadcast: t1 
    | t2 |
    t2 _ ScratchEvent allInstances.
    t2
        reverseDo:     
            [:t3 | 
            t3 name = t1 ifTrue: [^ true].
            nil].
    ^ false

Yeah, I copied this off rubiks man.

You are going to use a blockspec. Here is a list of them (place one of them in control):

('%e received?' #b #seesBroadcast:) shows [ (broadcast) received?]

('I receive %e' #b #seesBroadcast:) shows [I receive (broadcast) ]

('%e being broadcasted?' #b #seesBroadcast:) shows [ (broadcast) bring broadcasted?]

If you want a custom spec, just ask!

Actually, they are all correct.

%e received?  is saying you had received it. It is only temporary, and hardly functions to it's purpose.

I receive %e   is not a Boolean.

%e being broadcasted? makes the most sense. It says that the message is still a process, and can still be called.

The others cannot be called for more than 3 seconds.

Blah blah blah, I am bbbeb and I like to be rude all day posting junk like this...

I'm not saying they all make sense, I am just saying that they all work and can therefore be considered correct.

Uh, you forgot step 14-15!

14.If you want to save your changes, Shift-click-R and click "save image for end user"(or something like that)
15. Click "yes".
