oh, and unless you will be including the 'when %b is true' in panther,
can i have some help on how to make it?

when: t1
    t1 ifTrue: [^ true].
    ^ false

OK i'm not the best squeaker but something like that should work!

EDIT: this is more for ('%b is true') boolean. It works, I've used it. made it myself and it still works!

NOTE: has no real purpose.

@nXIII:
thanks!

although, i have one more question. how do you make the nested blocks repeat until a boolean comes true?

That's an already-defined special-form, I believe #doWhile, maybe?

hmm... i suppose so.
i'll play around with those forms.

Thanks for the mod EXE tutorial, do you know how to make it ask for a file type other than .sb? My mod's files are saved as .zp, and it only lets you choose a .sb file to convert to EXE.

LS97 can I ask you a question.

in squeak you have the code 'self' and then some code,
so in Panther you can have 'self setVar: () to: ()', do you know how I could do 2 of these in 1 block?

Yes your right, thank you so much. Ive been wondering how for ages!

Well, I forgot how, lol. See I learnt it, went on holiday, got back and forgot it. Ive been trying to work it out ever since 

True, but I like trying to do things myself

Ohh and 1 more thing:

You declare variables like this:

|t1 t2|
and sooo on

But how do you set t2 to 2 or something?

t2 = 2? Thats how its normaly done in other programming languages.

Dnt worry me and MP56 worked it out!

no you didn't.
here's how:

"declare them first"
| t1 t2 |

"then set them"
t1 _ 'something'.
t2 _ 'something else'.

the _ should appear as an arrow.
as for what key it is, it's a normal underscore.

EDIT:
to report what the variable is, use ^ (appears as arrow).
to use the variable in if statements, use the equal sign ( = ) like this:
t1 = false ifTrue: [do this]
             ifFalse: [do that].

How to repeat code a number of times like the repeat block.

XX timesRepeat: [YY].

replace XX by the times you want to repeat, YY by the command that's repeated. you can add more than one command in the YY bit, like this:

10 timesRepeat: [World doOneCycleNow. viewerMorph updateCategorySelectors.]

separate the two commands by a dot and you're done!

@EDIT:
Just pointing this out: (I've seen some very inefficient code like this)
this:

t1 ifTrue: [^ true].
^ false

is the EXACT SAME THING as this:

^ t1

and it won't throw an error if t1 isn't a boolean.

nXIII he was showing me how to do some squeak I forgot lol.

Go ask Jens if there is a way of editing the imagefile, but he said that he removed the Editor from BYOB, I guess so people couldn't steal the BYOB interface

No, no, we just want people to steal one we're proud of -- right now the code is not in distributable condition.  By the time of the Scratch conference in August we'll have an official release and it will have a dev menu with access to a browser.

Meanwhile, if all you want to do is add a simple block you can probably do it using Elements, which is Jens's Scratch-like drag-and-drop interface to the Smalltalk code.

Personally I'd be very happy if every Scratch modder includes BYOB in their mods!  I want to take over the world!  I want BYOB in Scratch 2.0!

Right now people are finding bazillions of bugs, and the program is incredibly slow, and you really don't want it in this condition, trust me.  We're truly grateful to all the alpha testers who've been putting up with the annoyances of 2.99 and reporting bugs.

To hack BYOB: make a turn fillscreen off block in the elements editor.
