I believe there's a block for that already...

Made by Jens as a change set (in 1.3)

Smalltalk cannot read Pitch. It has been confirmed already.

It is sad.

NOTE:
There's a second, more advanced version of the block, with a drop-down menu instead of a string inserter, but it involves extra coding. If you are willing to take the challenge, post and i'll edit this tutorial for you

im fine with extra advanced tutorial as it would produce less errors

please post

Thanks    (:

I've copied his way exactly. here it is:

ok. note that this is for the source code. if you are using normal scratch replace the 'code' with 't2'
into Scratch-Blocks > CommandBlockMorph > all > uncoloredArgMorphFor:
add a line that looks like this:
$t = code ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #timeDates].
back in ScriptableScratchMorph, create a new method with this code:

timeDates
^ #('time' 'date' 'short date' 'seconds' 'minutes' 'seconds' 'hours' 'weekday')

now replace the blockSpec you created with ('get %t' r getDate: 'time')

Replace the code with:

Code:

getTime: t1 
    t1 = 'date' ifTrue: [^ Date today].
    t1 = 'short date' ifTrue: [^ Date today printFormat: #(1 2 3 $- 2 2 )].
    t1 = 'time' ifTrue: [^ Time now].
    t1 = 'seconds' ifTrue: [^ Time now seconds].
    t1 = 'minutes' ifTrue: [^ Time now minutes].
    t1 = 'hours' ifTrue: [^ Time now hours].
    t1 = 'weekday' ifTrue: [^ Date today weekday].
^ 'Error!'

___________________________________________
I've edited the tutorial a little. LYSD didn't post the tutorial correctly.

thanks

ive edited it a bit to make it work on normal scratch

and also it says error when i use the block

thanks

the 'getDate' part in the blockspec has to be replaced with 'getTime'.

I also have two more date pieces to insert in the 'getTime code:

 
t1 = 'month' ifTrue: [^ Date today month].
t1 = 'year' ifTrue: [^ Date today year].

After you placed the code, insert this strip into the 'timeDates' code after 'weekdays':

 'month' 'year'

Now you can view month (month with year) and year alone with your 'get time/date ' block!

can you make me a (last brodcasted) block
PLEASE!!!

This block works, but for some reason, there is a separate block for each sprite. (i.e. each sprite has a checkmark next to this block, but all the values are the same. Does that make sense?)

Go to Scratch-Objects>>ScriptableScratchMorph

Add a class variable called LastMessage. To do this, find the list of class variables, and add LastMessage to it, separated from the other items with a space. This would probably make the code look like this:

Morph subclass: #ScriptableScratchMorph
    instanceVariableNames: 'objName vars lists blocksBin isClone media costume costumeChangeMSecs filterPack visibility volume tempoBPM sceneStates '
    classVariableNames: 'BlockColorDict BlockSpecDict DefaultBackgroundForm DefaultSpriteForm DoubleSize Experimental LastMessage ListBlockColor MeowSound OldMeowPrefixReversed PopSound RandomGen Recorder ScratchOrigin TimerStartMSecs '
    poolDictionaries: ''
    category: 'Scratch-Objects'

Then go to Scratch-Objects>>ScriptableScratchMorph>>accessing

Replace the text at the bottom with the following code.

lastMessage
    ^ LastMessage

Save that (Alt+S) then click accessing again. The text at the bottom should be replaced by the method template. Replace that with:

lastMessage: t1 
    LastMessage _ t1

Then go to Scratch-Objects>>ScriptableScratchMorph>>other ops>>broadcast:
Replace the text there with:

broadcast: t1 
    self broadcast: t1 withArgument: 0.
    self lastMessage: t1

Go to Scratch-Objects>>ScriptableScratchMorph>>other ops>>broadcast:withArgument:
Replace the text there with:

broadcast: t1 withArgument: t2 
    | t3 |
    (t3 _ self ownerThatIsA: ScratchStageMorph) ifNotNil: [t3 broadcastEventNamed: t1 asString with: t2].
    self lastMessage: t1

Finally, go to Scratch-Objects>>ScriptableScratchMorph>>class>>block specs>>blockSpecs

Choose where to put your block, and add the following block spec:

('last broadcast' #r #lastMessage)

If someone finds a problem in my work, or finds a better way to do it, please correct me.

Can someone please make me a booklean version of the "When I recieve block"? PLEASE

It works!
If you go to Scratch-Blocks>>CommandBlockMorph>>private>>canBecomeWatcher and add the text #lastMessage with the rest, it won't show on the stage.

That sort of solves the problem. You see, the problem is not that it shows on the Stage, it's that it shows as a local variable of each sprite. For example, "answer" is a global variable, and is shown on the stage once.

last broadcasted shows up on the stage separately for each sprite, but they all have the same value because you can't have local broadcasts.

like this:

This doesn't work

I know. I don't know where is the thing that determines if it's global or sprite specific. Probably in Scratch-UI-Watchers.

I did a bit of searching, and found this method at Scratch-Objects>>ScriptableScratchMorph>>class>>other>>isSpriteSpecificTarget:Selector:

Here's the code currently there.

isSpriteSpecificTarget: t1 selector: t2 
    | t3 |
    (t1 isKindOf: ScratchSpriteMorph)
        ifFalse: [^ false].
    t3 _ t2 asString findAnySubStr: #('answer' 'key' 'Loud' 'mouse' 'sensor' 'soundLevel' 'tempo' 'timer' ) startingAt: 1.
    ^ t3 > t2 asString size

Could someone please explain this to me? For last broadcast, it returns true, which causes my problem. I tried just writing ^false, and it worked fine, but local variables no longer had the name of the sprite before them.

I found this method through Scratch-UI-Watchers>>WatcherMorph>>initialization>>target:selector:parameter.

It would help if someone explained that to me too...I'm rather confused...

[blocks]<when[ any ]key pressed>
<key[ any ]pressed?>

I would like these blocks.
I tried making them myself but failed.
I would like mabye a tutoriol.

More blocks requested:
<change[ blur ]effect by( 25 )
<set pen color to( r: g: b: ) [/blocks]

Hey! I found out how to make repeats!

I wrote:

Here's how (follow this pattern):

Code:

<selector name>
    | repeatclient |
    repeatclient _ <number of times it should repeat>
    self <selector name> + <repeatno: repeatclient>

Code:

<selector name> + <repeatno: repeatclient>
    repeatclient = 0 ifTrue: [^ self].
    <coding to be repeated>
    self <selector name> + <repeatno: repeatclient - 1>

Quoted from the block library

I don't think you ever gave the link to the show/hide list blocks, so here it is: http://scratch.mit.edu/forums/viewtopic.php?id=32494 by nXIII
