I think Zorket probably misunderstood "How do I get what they typed in?" meaning something to do with how he used BBcode, and added the mistake so the bbcode would show up...

Zorket, What people are trying to say is:

Once you have run the block you posted, how can a user read the text you typed into the string dialog in the same way that you need to read the "answer" to the "ask" block with a reporter.

In answer, the block Zorket posted IS a reporter. It asks the question and then reports the answer.

yes! I'm updating as we speak.

Thanks for the tip, sparks.

I have made another block. Wrote it myself.
[open user page]

blockspec:

'open user page' #- #openUserPage

Code:

openUserPage
| t1 |
t1 StringDialog askWithCancel: 'user name:'.
t1 size = 0 ifTrue: [^ self].
Cursor wait showWhile: [ScratchPlugin primOpenURL: 'http://scratch.mit.edu/users/', t1]

oh. i made it a command block

EDIT:

its reporter now. it just says "A ScratchSpriteMorph()" when it gets input

Gives out the selected constants. Note the better arrows '»'

Meant to replace the pi block Zorket and I gave.

If you want to add a constant, just tell me.

have you made any custom blocks in scratch?
have you made projects with them?
are you annoyed that you are the only one who can run them?
do you wish you could share those projects?

now you can!

put a link to the project here, along with the blockspecs and coding for the blocks

What are you going to do with 32 scratch blocks if not use them in projects?

sparks · 2010-12-09 09:51:19

@ Zorket, Thanks for the user block, but I've already made one. Mine does not ask the name of the user in a dialog, but I think that's better because otherwise you have to have a dialog box asking to input a user hmm Also, what tip and how is it broken?

@Hardmath123, sorry, I must have missed it, I'll add it in a bit smile

@me450, I tried zorket's ask as reporter block code and it worked for me... you must have made a mistake somewhere.

@scimonster, what?!

if you make all 32 blocks you have here, what are you going to do? look at them for fun. no. use it in a project. and what's the point if you can't share it? thats what this topic is for, projects that use custom blocks.

The penshade block has already been shared here I'm afraid hmm But thanks for your submission!

MathWizz · 2010-12-10 11:42:13

Tada!

BlockSpec:

Code:

('if touching %m bounce' #- #bounceOffSprite:)

Code:

bounceOffSprite: aName 
    | sprite oldDir |
    sprite _ self coerceSpriteArg: aName.
    (self touching: sprite)
        ifFalse: [^ self].
    oldDir _ self heading.
    self pointTowards: sprite.
    self turnRight: self heading - oldDir + 180.
    [self touching: sprite]
        whileTrue: [self forward: 1]

Not bad for my first block in the library, eh?

It's not very accurate right now... It assumes the sprites are circles, but it can still be useful.

I have a new untested block called (letter () ).
Untested, again.

blockspec:

('letter %n' #r #letter:)

LONG code:

Code:

letter: t1
t1 = 1 ifTrue: ^ 'a'.
t1 = 2 ifTrue: ^ 'b'.
t1 = 3 ifTrue: ^ 'c'.
t1 = 4 ifTrue: ^ 'd'.
t1 = 5 ifTrue: ^ 'e'.
t1 = 6 ifTrue: ^ 'f'.
t1 = 7 ifTrue: ^ 'g'.
t1 = 8 ifTrue: ^ 'h'.
t1 = 9 ifTrue: ^ 'i'.
t1 = 10 ifTrue: ^ 'j'.
t1 = 11 ifTrue: ^ 'k'.
t1 = 12 ifTrue: ^ 'l'.
t1 = 13 ifTrue: ^ 'm'.
t1 = 14 ifTrue: ^ 'n'.
t1 = 15 ifTrue: ^ 'o'.
t1 = 16 ifTrue: ^ 'p'.
t1 = 17 ifTrue: ^ 'q'.
t1 = 18 ifTrue: ^ 'r'.
t1 = 19 ifTrue: ^ 's'.
t1 = 20 ifTrue: ^ 't'.
t1 = 21 ifTrue: ^ 'u'.
t1 = 22 ifTrue: ^ 'v'.
t1 = 23 ifTrue: ^ 'w'.
t1 = 24 ifTrue: ^ 'x'.
t1 = 25 ifTrue: ^ 'y'.
t1 = 26 ifTrue: ^ 'z'.
^ 'Error!'

What I have to say that every block I say is DEFFERENT. And I work HARD on them. So please, PLEASE add them! I'm begging you!

[blocks]<rotational direction[/blocks]
HI
I would like a block that senses clockwise and counterclockwise motion.
I have a scratch project with a dial that turns to the mouse pointer but even when you are turning the opposite way there is the same event. I want 2 events for this button 1 for turning clockwise and one for turning counter-clockwise. Thanks

SSBBM · 2010-12-10 21:12:02

Man, I have no idea what you guys are saying with your scratch code. Could anyone help me with coming up with BYOB block?

And I'm over here, wishing that people would stop coming up with BYOB blocks, 'cause I'm getting overloaded with building the BYOB Block Library project. tongue

sparks, can you compile a list of BYOB blocks not in the project and provide easy access to them? 'Cause I'm, er, sorta behind tongue
