Scimonster made one, I think.

Ahh... so you made that, great! Job.

Here's where I learned from.

Oh yeah...

I already knew how, thats how I made it. But I didn't make it, nice tutorial.
@Librarians: Should we link to that tutorial somewhere?

Yeah, in the first place how to make a cap block.

No, I think it is better in the glossary or something, in the first place it would be hard to find, we could in the first cap block say to look in the glossary for what a cap block is an how to get it. 

That's a better idea. 

I have an idea for a new scratch block:


Blockspec:

('%n ≠ %n' #b #notequal:to:)
NOTE: The ≠ symbol might not always be available. "not =" also works.

Code:

notequal: t1 to: t2
t1 = t2 ifTrue: [^ false].
^ true
This block will report the truth value of two values are not equal.

Sorry, I do not have a picture of what the block would look like.

('Copy %s' #- #copy: #'some text')

copy: t1 
    ScratchTranslator unicodeClipboardPut: t1

Scimonster's block ported to Scratch.

I have a Panther block :D I don't make blocks often but I really was getting fed up with dragging out all the blocks to make <<(mouse x) < ( )> and <(mouse x > ( )> and <mouse y < ( )> and mouse y > ( )>>. I use this one with the mouse position reporters to make check if the mouse is within a square space on the stage. Great for stamping projects where you can stamp or draw on parts of the stage but not on the toolbars to the side of the "canvas". Will add it to the library in a second!

|result|
result_true.

t1 <= t3
ifFalse:
[result_false.].

t1 >= t4
ifFalse:
[result_false.].

t2 <= t5
ifFalse:
[result_false.].

t2 >= t6
ifFalse:
[result_false.].
^result

No. funnily enough canvas is a material used to paint on. In paint projects the area you can draw on is usually called the canvas.

Oddly, I forgot to declare the variable "result" in the above code and yet the block worked perfectly... is result a pre-existing variable in smalltalk? (I've added it now to be on the safe side)

I knew that, it just seemed like a HTML5 reference.

What is a canvas in HTML5? I've never heard of it. It sounds like a space in a webpage where media can be drawn or rendered?

Got it in one. Its a paint canvas where images, videos, or colours can be rendered. E.G HERE DOES NOT WORK IN IE!

That is incredible! I must learn about this at some point! (I completely guessed what a canvas in HTML5 does    )

is anyone going to add my scratch blocks? please?

please? I shard like 5 scratch blocks and they're not added. or made with scramble.
