if you use the elements editor: yes.
if you use BYOB blocks: no.

(pi)

Blockspec:

('pi' #r #givePi)

Code:

givePi
^ 3.141592653

This is very few of the ∞ Digits of Pi.

Another request of SeptimusHeap.
Put this code in both Sprite and Stage Morph blockSpecs in the sensing category:
Code:
 ('%s mouse down?' #b #mousePressed: 'left')
then into the instance, into ScriptableScratchMorph, and into 'sensing ops'.
replace the 'mousePressed' code with the one below.
Code:
mousePressed: t1 
    t1 = 'left' ifTrue: [^ Sensor redButtonPressed].
    t1 = 'right' ifTrue: [^ Sensor yellowButtonPressed].
    t1 = 'middle' ifTrue: [^ Sensor blueButtonPressed].
    t1 = 'any' ifTrue: [^ Sensor anyButtonPressed].
    t1 = 'left ' ifTrue: [^ Sensor redButtonPressed].
    t1 = 'right ' ifTrue: [^ Sensor yellowButtonPressed].
    t1 = 'middle ' ifTrue: [^ Sensor blueButtonPressed].
    t1 = 'any ' ifTrue: [^ Sensor anyButtonPressed].
    ^ Sensor redButtonPressed
Then click accept and it should be fine. you'll find the new block in the sensing category. you can put left, right, middle or any into the box and it'll give you the respective sensor button boolean.
i want a dropdown list version of it.

Arragh, this is frustrating doing this. Here:

ScratchBlocks/Commandblockmorph/all/uncoloredArgMorphFor:

$z = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #mouseButtonNames;
choice: 'left'].

ScratchObjs>ScratchSpriteMorph>sensingOps:

mouseButtonNames
^ #('left' right' 'middle' 'any' ).

New blockspec:

('%z mouse down?' #b #mousePressed: 'left')

Hi, first of all, great tutorial!!! I am a beginner to Squeak, and I was wondering about how you decide where to put the
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 = 'day' ifTrue: [^ Date today weekday].
t1 = 'help' ifTrue: [^ 'type date, short date, time, seconds, minutes, day, hours'].
^ 'Error!'
because it seems sort of arbitrary to me at this point. Once again, great tutorial!!!

Still not tested. The first code is more likely to work. If neither work, tell me.

That really does give a lot of numbers, but if you want a nice and user-friendly version you can just write ^ Float pi to get the constant of Pi!

I like writing ^ 0 pi better tongue

givePi leads to the givePi code. Add the code in instance, other ops and replace the code of broadcast with the correct code.

Everything is possible to code, unless it's like the block below:

[If touching pen, open the water bottle]
But I think the one below IS possible:

[If touching (a sprite), die]
