Right, so my class is having a competition on who can make the best cutom blok, but my teacher said we can't use any of the online blocks, and it looks like she's blocked pretty much everything. I have NO idea of squeak stuff and I came up with...

Get IP Adress!!

But this is what i wrote:

Get IP Adress t1:

t1 = getIPadress


None of the tutorials I have seen have helped so it would be really nice if someone told me how, not do it for me.

Its a reporter right? Well, if it is, that method doesn't return a value, so add

^ variable

where variable is the thing you want the block to report.

Does this help?

Off the top of my head, I don't know how to get the IP address myself, so I coudln't give you a hint in that direction.

If you want to make a reporter block, it has to actually return something in the method itself. To do this you need to add the ^ sign, then put what you want to return after it.

Also I don't think you need the t1, so remove the t1 in the top line, and then put that code you've got after the ^ sign to return it.


Is that better? I could write a fully blown explanation on how to make a block if you like. When have you got to do this by?

this is.... odd. You're 10 and your teacher is making you code your own blocks?! most 10 year olds just about stick the blocks together... What are you doing this in? Scratch itself or a modification like BYOB or Panther?

representing the school? that's pretty neat    In that case we definetly don't want to give you actual block code, but there are TONS of tutorials around this section of the forums!

Monday, If I do it, I get to represent my school on who can make the best scratch project, if I win I get put on the school's hall of fame and win the school £1,000 so it's pretty important. I just made a previous costume without looking at anyone blocks, but I could use a fully blown explanation.

^ best scratch project? you don't need to code your own blocks to make a good project. It's more the application of blocks that should win you points...

Noo... The person in our class that make the best blocks, I have no idea though, I understand your view. But we need to use 3 custom blocks in our best project.

I can help with most blocks, but I dont think a IP block is very useful. Also I believe the code is already online somewhere so...

ok then.

So open up the folder where the Scratch.exe is. You can see .dll files right?
These are plugins.
Are you with me so far?

Your teacher is asking 10 year olds to code blocks in Smalltalk!?

yep,but could you try to upload all of it in one go?

Ok. So these plugins can be called from within small talk (the language scratch runs in)

Heres how you call the web page plugin
(HTTPSocket httpGet: variableHere)

so using this you can code:
|variableHere page|
"This declares the variables"
variableHere_ 'page url'.
"This sets variableHere to page url"
page_ ((HTTPSocket httpGet: variableHere) contents).
"This gets the contents of the page variableHere"
page = 'Server  is not responding"
ifTrue: [
page_ ''.
].
"This makes the page set to nothing if the websites down or non-existant"
^ page
"This reports the page value"



On to the next step the code.

Your block needs to look like

getURL: variableHere
| input page|
input_ variableHere asString.
page_ ((HTTPSocket httpGet: input ) contents).
page = 'Server  is not responding"
ifTrue: [
page_ ''.
].
^ page

the getURL: bit is the name of the meathod.
':' is a input.
So in this case we are setting variableHere to a input.

Now to the block spec
Your block spec should look like:

('get url %s' #r #getURL: '')
Ok the %s is a string input (a box)

#r means its a reporter

#getUrl: is the meathod name

'' is the deafault value





Congrats you have made a get URL block!

ok ignore that bit then

What do you mean?

Like, say if a page had text, set it to a variable
