We can gain more codes by opening squeak. In the pick random code where I just checked, contains something else.

what do you mean by that??

I can't figure out how to make the Graphic effect reporter block... can someone help?

Here it is just quickly. i've got hw to do now!

Code:

getEffect: t1 
    filterPack ifNil: [^ 0].
    'blur' = t1 ifTrue: [^ filterPack blur].
    'brightness' = t1 ifTrue: [^ filterPack brightnessShift].
    'fisheye' = t1 ifTrue: [^ filterPack fisheye].
    'color' = t1 ifTrue: [^ filterPack hueShift].
    'colour' = t1 ifTrue: [^ filterPack hueShift].
    'mosaic' = t1 ifTrue: [^ filterPack mosaicCount].
    'pixelate' = t1 ifTrue: [^ filterPack pixelateCount].
    'pointillize' = t1 ifTrue: [^ filterPack pointillizeSize].
    'saturation' = t1 ifTrue: [^ filterPack saturationShift].
    'transparency' = t1 | ('ghost' = t1) ifTrue: [^ self transparency].
    'whirl' = t1 ifTrue: [^ filterPack whirl]

Hope it helps.

where do you put it?

i would suggest ScriptableScratchMorph -> looks ops

Too long for it to process. 

well, in fact, the program will only process it to about 20 decimal places (i think its about that) then round it. so no use in making it longer!

(that's why you dont use it for math)

If you return it as a string you can get the entire thing. And e has (almost) nothing to do with circles. Random fact: e^(iπ) = -1. I found a proof in Professor Stewart's Cabinet of Mathematical Curiosities. (Or maybe Hoard of Mathematical Treasures.) They're both good books. I recommend them.

Oh yea, what is it... e^iθ = i cos θ - sin θ? I forget....

Place it in control.

Code under other ops:

seesBroadcast: t1 
    | t2 |
    t2 _ ScratchEvent allInstances.
    t2
        reverseDo:     
            [:t3 |

Do not upload, for 2 reasons:
1. It becomes obsolete!
2. It doesn't work online (really.)

ScratchPlugin primOpenUrl: 'http://web.address/'

[Tutorial - Compile to exe with custom blocks]
1. Download latest BYOB
2. go to BYOB folder
3. Look for BYOB Development.BAT
4. change shortcut to open that file
5. open BYOB via shortcut of batch file
6. Shift click edit
7. turn fill screen off
8. add all your custom blocks and use BYOBS compiler to compile your projects

Here's my tutorial:

1.) Open scratch, shift click in the loop in R:

Open the editor.
Then click on the white space that appears, go to open-browser.
2.) The browser should look like:
You really should be working on 1.4.
Go above, and click scratch objects.
[Scratch sprite morph for sprite only blocks, Scratch stage morph for stage blocks only, and ScriptableScratchMorph for both, go to ScriptableScratchMorph in the example, please]
Then you go LOW and press class. then go to the third pane, click blockspecs//scratch. In the 4th pane, blockspecs.
3.) Here's a really hard step. You have to locate yourself where the blockspec goes!
Alright. If you are following the tutorial, you should be in ScriptableScratchMorph.
Find 'control'. look across the line, and you will see a #-. Use a #- when you want to put a space in. And you will find a ('repeat %n' #c #doRepeat 10).

The block contents is first in the brackets. There have to be brackets for strings, always. example: 'repeat %n'
________________________
The #c tells what type of block this is. Here is a list:
#-   no arguments (command or 'stack' block)
#r   Reporter block (the round ones)
#b   boolean block (diamond shaped)
#c   C shaped block (like the forever block)
#t   Time block (like wait X secs)
#W   'when' hat block (obsolete)
#S   start button click hat block
#K   key-activated hat block
#E   event hat block (broadcast)
#s   special form (hard to code)
Credit to ls97 for this list.
______________________
The #doRepeat 10 is the command. It has to be exact to the name of the code.

You also might be wondering what the %n is doing there.
This indicates a numberical inserter. Here is a list of them:

a:  attribute of another sprite, such as X position or size.
b:  a boolean inserter
c:  a colour picker that shows the menu.
C:  a colour picker that doesn't
d:  the sprite direction menu/numerical inserter.
D:  the menu for midi drums
e:  The broadcast message menu
f:  math function menu (with sin, abs, etc.)
g:  menu for the different graphic effects.
h:  numerical sensor board selector menu
H:  boolean sensor board selector menu
i:  midi instrument menu/numerical inserter
k:  menu for the names of the different keys, used in the key sensor blocks.
l:  menu with the costume names of the given sprite.
L:  list name menu.
m:  sprite list
n:  numerical inserter
N:  note name menu/inserter
s:  string inserter
S:  sound selector menu
v:  variable labels menu
y:  menu used to delete either a number of the last value or all of a list.

Credit to ls97 and billyedward for this list.
Alright, for the tutorial, were gonna make the ( report (hello) ) block. Add the blockspec: ('report %s' #r #report: 'hello') Place it in control or operators.


4.) Now were going to move on to codes. Some blocks already have the code installed.
For the ( report (hello) ) block were doing, there is a place were gonna put this code.
Click on instance in the 2nd pane low. In the third pane, other ops, and the 4th, add new code or replace any code. Use the code for the ( report (hello) ) block:

report: t1
^ t1

this is the short code. Accept.
I'm gonna help you figure out more stuff. Here's an extra-long helpers code:

report: t1
| t2 t3 |
t1 _ t2
t2 _ t3
t3 = t1 ifTrue: [^ t1]

The | t2 t3| adds the variables t2 and t3 to the code.
t1 _ t2 makes t2 equal t1.
t2 _ t3 makes t3 equal t2.
t3 = t1 ifTrue: [^ t1] checks if t3 = t1, if it does, it does the command inside [], and ^ makes it report t1 (the string)
There you go! With a little practice, you can make your own blocks! Oh, I almost forgot. Close the green code, and turn fill screen on with the first in step 1. If you are positive you want this block permonant, use the shift-click methood and click save-image.

With this tutorial, there are no bondaries for blocks.
You can even make a [if touching (a sprite), die] block!!!

you dont need a password to combine blocks... Squeak isnt always the simplest answer to everything!
