forget block maker, edit it with the source code!

I've tried, but can't get the code up and working. I download it and all, but where is it located for Mac's!!!???

personaly I agree with you (Cyclone103), that arrays are very usefull, but maybe that isn't the idea of Scratch to use such complex variables. But I'm looking forward to could use procedures. Without them it's hard to avoid a mess in the code.

It's been over a year since this request for comments was posted: are the Scratch team any closer to finalising some sort of procedural abstraction?  Is there a timeline for implementing it?

I posted this elsewhere but I think this is the place to do it.
My idea is that you could make a function just like youd make a sprite like this below:



A function wouldn't have a number of inputs (like variables) and one variable called output, that you have to set at the end of the script, functions would have no costumes or sounds just sripts like this one here that has just 1 input, this function is for squaring a number (ie a number times by itself)



When you make a Function you also get allong with it a new block in the section like this:



and the block has the same nuber of inputs as the Function, from the code this is what would happen if you used the square block:



And here's anothe possible one, this one has 2 inputs and works out the size of the difference between 2 numbers (ie there's no minuses involved):



With this Function of course you also get this block:


What you could also do is make a function that uses other functions that you've already made like this one for calculating pytagorases theorum for calculating the length hypotinuse of a right angled triangle from the length of the other 2 sides.

So the inputs here are the lengths of the two other sides of the triangle:



and making this function creates this block:




I have an example of how I currently attempt to tackle functions "my stuff"

I think that the current block type needed most is an array. Arrays allow retention of more data than a variable. If that block were to be added, it would probably go under variables, and a good color would be yellow. If an array block was added, everyone could expand their work much easier, since only one "variable style block" would be used for storing massive amounts of data.

arrays are in scratch 1.3 i can secretly go in 1.3 candidate and there is a block maker type %a %b %c %d %e %f in a variable this breaks 1.2.1 until the variable is deleted

One block that I would like would be [blocks] <[  <=>  ]> [/blocks], that existed in NetScratch. Now, text input was discovered, and I would like to do passwords, like this:
[blocks] <if> <[ (Item (1) of List  <=> Password) ]>
<broadcast[ Correct Password
<end>
[/blocks]

Hey, Jens posted a project about how to create custom blocks!

http://scratch.mit.edu/projects/Jens/75626

http://www.freewebs.com/scratchclubsite … %20Tab.gif http://www.freewebs.com/scratchclubsite … 20Tab2.gif. To make a block you would have to click this: http://www.freewebs.com/scratchclubsite … 7361717941. The block could hold several blocks inside like this:http://www.freewebs.com/scratchclubsite … 0Block.gif http://www.freewebs.com/scratchclubsite … 0Block.gif

I like the idea of having a feature in the right-click drop-down menu for a GROUP of blocks that says something like <convert...> and then you click on it, and you type in the wording for the block, so then all the blocks you selected are consolidated into one, and in THAT one's menu, it will have an option like <add...> where you could add a new block to the commands of that new block.  Then, all series of blocks identical to what was put into that block (in that project) would convert to that block.

how about a extra category that is custom blocks and you can say create new block then drag a group of blocks into the new block then name it and it will work as a single block?

i think there should be an <if recieved(dropdown arrow)> block, that would be very useful for several of my current projects (sry if this is in rwrong forum, there were so many different sub forums)

Jens has made a block editor. Go to chirp.scratchr.org.

yes i think the yellow blocks shold be called: website
like making a way to make the sprite dragable on website at certain times
