Scratch

Off topic: It has to do with this, I think...

On topic: For long scripts, sometimes it can go far enough that you reach a point in which it can't... I don't know the perfect way to say this.

Yea... they are blocks I made by modifying the blockSpecs. Interestingly enough, all of them use already-defined functions. I find them very useful, along with my 'sprite name' blocks, etc.

For some of those made-up blocks, couldn't you just use a list?

Yes but mine are a lot faster. no parsing, just BOOM. They work. And sprite name and ascii blocks don't have anything to do with lists...

I just can't figure out how to make the blocks actually work... i know how to make them, though.

But you're a Whiz! You have to know! 

I wish I knew.

OK, now that I have BBCode and no 500-character limit:

1. Turn fill screen off (by shift-clicking on the R in the Scratch logo)

2. a) Open the world menu by clicking in the whitespace
    b) Click Open..., browser

3. You can make the window that pops up a bit bigger, if you want, by clicking near the corner and dragging, or click the menu icon near the top left and selecting fullscreen.

4. Select Scratch-Objects, then:
    a) Click ScriptableScratchMorph if you want your block available to both the stage and the sprites
    b) Click ScratchSpriteMorph if you want your block to be available to just the sprites
    c) Click ScratchStageMorph if you want your block to be available to just the stage

5. Click the category you would like to put the function in (or ctrl-click and click new category...

6. In the bottom panel, delete the selected text

7. Type the function name in the following format:

name: t1 nameContinued: t2

Where name and nameContinued make up the name of the function (split between the arguments, t1 and t2)
For example:

setVar: t1 to: t2

8. If you use temporary variables in your function, on the next line put the variables, separated by spaces, between two '|'s. For example:

| t3 t4 t5 |

9. On the next line, write your code, for example: (this opens a SystemWindow with the given label, sorry I didn't have time to make it display text too)

openWindow: t1
    | window |
    window _ SystemWindow new.
    window setLabel: t1 asString.
    window openInWorld: World

VERY IMPORTANT NOTE: the _ (underscore) character is used for assignment; it appears as a left-pointing arrow.

10. Press alt + s to save your changes

11. Click class where you see the three buttons instance, ?, and class

12. Add to the blockSpecs the correct spec for you block, with the format:

('spec %s etc.' #symbol #callToMethod 'defaultArg')

For example (using my method above):

('open window (label %s)' #- #openWindow: 'A Window!')

See this forum topic for specifics on making blockSpecs

13. Press alt + s again

14. Close all windows and turn fill screen back on

15. Click your new block to test if it runs properly

Wow... thanks!

I have a couple questions
1. What OS do you use?
2. How much RAM do you have in your computer?
3. Did you try to optimize your project?

Without answers, I won't be able to help you.

Um... XP, 2GB, kind of.

Okay uhh...

#1: Have you tried a newer version of Windows?
#2: That is the same amount of RAM that I have!
#3: You might have to optimize it a bit more... *long pause*

It has nothing to do with what OS he's running, it happened to my Mac.

This is getting off-topic ...

ThePCKid...
XP is one of the slim-est OS's. It's better to use XP than Vista or 7.

Mathematics...
It isn't really that off-topic. I posted a screenshot with nonexistent blocks, so what would you expect?

Yes - this is a bit of a glitch. 
Scratch sets aside a certain size memory buffer in which to store the image for each Script. When we designed it, we never imagined that 1S1S would become a trend, so we just set it to a size which, for most projects that use multiple scripts, is way more than you'd ever need. But with large 1S1S projects, that limit is sometimes crossed. So the picture of the script just ends.  oops!

I think RHY mentioned that they actually code things in two scripts, and then stick them together just at the end. So you could try that technique. Hope that helps
