And there u have it!

That didn't work for me.

Look at 2 things:
the hats
and the execution engine.

Actually, most of the time you don't need to bother with the execution engine. The script starting is done in the hat block, it just creates an instance of ScratchProcess - the main class in the Execution Engine - which then works by itself. You just need to code the hat block, and that can be done most of the time by tweaking existing hat blocks.

BTW - How do you access all existing instances of an object? If it includes the keyword allInstances remind me to kick myself. And how can I make the scratchProc and proc instance variables of a hat block morph dictionaries? Never mind why, I'll post if my idea works.

I was making pause/play blocks, and to make them work for every currently running script I need to access each existing instance of ScratchProcess.

EDIT: I've just had a thought. Maybe I could create a class variable in ScratchProcess called IsPaused and make the execution engine check that before it executes the next block.

I got a new block

Instance ops:

Code:

| dialogBox |
    dialogBox _ DialogBoxMorph new.
    dialogBox title: t1.
    dialogBox withButtonsForYes: false no: false okay: true cancel: false.
    dialogBox message: t2.
    dialogBox getUserResponse.

Blockspecs

Code:

('show dialog titled %s with contents %s' #- #showDialogTitle:Contents: 'info' 'hello')

What does it do?

Is there a block spec and method/code for the following blocks?

<undo pen> & <redo pen>

It opens up a dialog box titled whatever you want to say same for contents

Use this code instead.
dialog inform:t1 with title: t2
     DialogBoxMorph inform: t1 withTitle:t2

not at the moment, i might have the patience to make it. but it sure will take a lot.

nothing is impossible to code. even if you had to code scratch from scratch. but it's still not impossible.

there was no pun intended there. laugh if you please 

There is absolutely no point in creating a pause block. Why? Because how will it know when to resume if nothing is running? It can't. So you don't need the play either. If you want to make a pause, make it the BYOB3 way, like next to the green flag and stop sign.

or have
pause all other scripts.

spriteExists: t1
World submorphsDo:
   [:t2 | t2 isKindOf: ScratchSpriteMorph ifTrue: [t2 objName = t1 ifTrue: [^ true]]].
   ^ false

I think this would work but as I haven't tried it I don't know.
