Scratch

Here's my BYOB block, "[] = []" ! I know you're all like "There's already a [] = [] block!", but this block is built to get around the case-insensitiveness of the standard [] = [] block. Usually Scratch will report A=a as being true (even though one is uppercase and one is lowercase), but my block gets around this by using the ASCII values! Here's the code, enjoy! http://concat.jcshome.org/stuff/equals block.jpg

oh very nice! Good use of the ascii blocks! I'm putting that right up!

Thanks! 

Here is the code for the <pen down?> block: ('pen down?' #b #penDown)

Uhh... You got my block wrong. It is a diamond shaped block, and it ha #b, not #R. But thanx for adding it to your main.

Thats a brillant idea, nicely done.

How do I save the image for a BYOB block?

The block
make sure that the scripting area is clear besides the block you want to take a picture of.
then right click on the scrpting area background and click save pciture of scripts.
The code
Option 1. (You can do this unless you use the report area below the scripting area)
Do the same as The block
Option 2. Right click on the stage and click grab screen region, then click and drag on the area of the scripting you want to save. then export the costume.

ah    thank you, that was a mistake on my part, I should have put b not r, so I'm afraid that that block has been shared already 

oh cool

or
^ 0 - t1.

lol.
it makes it easier!

I've got a new BYOB block!

I got the idea from one of coconut's projects.

Panther block:
first box:
Create squeak error
Second box:
g
third box
self duplicateNoAttach

this block couldn't have less of a point, unless you want a squeak error.

Welcome to your block library! One of the most important and beloved features of Scratch are the blocks, and a great deal of time and effort has gone into making the blocks you see. When building Scratch, the team specifically designed the code so that it would be as easy as possible to add new blocks, and many people have done just that!

This topic aims to bring together a collection of useful block code for experimenting Scratchers to try out and learn from, embracing the program and share parts of the Scratch Motto and hopefully letting users use what they learn here to imagine their own blocks!

This library currently deals with three types of block, and they are displayed under separate headings with explanations or explanatory links to avoid confusion. The three types are

Scratch Block
These blocks can be added directly into scratch.

BYOB Blocks
Built in the popular version of Scratch, BYOB blocks are composed of many other blocks and the code for these will probably be displayed as a block image.

Panther Blocks
Another popular version of Scratch, Panther has a "make a block" feature that lets users easily write block code to do pretty much anything.

So to all you curious Scratchers and viewers alike, I bid you welcome. Welcome to the Library!

How to add one of these blocks to Scratch:
I suggest visiting this excellent forum page. It has a full explanation from Billyedward. You can also look at this detailed explaination on the layout of blockspecs by ScratchReallyRocks

how to add one of these blocks:
You need to download BYOB (Build Your Own Blocks) from this link to use the blocks shared in this section. A really helpful guide to understanding how to build your block can be found at this forum thread

To save space on this thread, any BYOB blocks shared will be displayed as links to images, rather than embedding the images to this thread directly. Just read the block description and click the link to the image if you want it.

How to add one of these blocks:
To use the Panther coded blocks, you need to download Panther from this link.

To add a block code, you need to open Panther, go to the variables tab, scroll down and click the "make a block" button at the bottom. You will get a popup window with three text boxes and a colour square. The long thin one at the top needs to have the block name in it. The square one to the right with a "-" in it defines the type of block (reporter, stack etc.) and the large one below them is for the block code.

thanks for sharing! ... any reason why it's a colour reporter? (theyve been taken out of 1.1 and replaced with normal variables that can reprort colours  )

well, a reporter will work as well I think.
