Scratch

I just started working with Scratch Mods today, and have a few questions about how some functions work.  For starters, where do you put codes for scratch blocks?  In the block library, there is a code section, but I have no clue where you would put them.  Secondly, how do you create new files in the squeak browser?  For instance, I'm trying to put in the change rotation style to %r block.  I have %r set up, but don't know where to put the list of options it gets its data from.  And third, where do you find option lists so you can edit them?  I'm trying to restore the obsolete graphic effects to the color effects menu, so in addition to the usual color/mosaic/ghost/whatever options, pointillize, saturation, and water ripple would be present too.

You may want to see the Modding Tutorial.

yes, I'm using the scratch program.  and I already know all of the stuff from that tutorial.  I'm trying to make the change rotation style block.  I can't figure out where you would add the data for the drop down menu so it does something.

The code from the library is this:

('set rotation style to %r' #- #rotationStyle:)

rotationStyleChanger
    ^ #('normal' 'leftRight' 'none' )

$r = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #rotationStyleChanger;
         choice: 'normal'].

I know where to put the first and last codes there, but where on earth do you put the middle one?  And for that matter, how do you create new data files?  I take it that rotationStyleChanger will have to be a new file for it to work properly.

And with regards to my other request, I'm trying to make it so the graphic effects blocks can have saturation, pointillize, blur, and water ripple in the drop down menu.

Where would I find the drop down menu that I can edit to do that?

I also was wondering where to put the code for new blocks...

Aaaaaaaaah, this is ridiculous!  I've searched for hours, and I can't find anything.  Kudos to MIT for hiding stuff that would allow tampering with the code so well.  I can't find those drop down menu choices at all, I can't figure out how to code new commands for the program to execute...  blargh.  And another question, I've noticed Panther and BYOB both have new block classes (panther has colors and files, BYOB has other).  How were those made?  And jwosty, to adapt my question to how you worded the answer, since the image is divided into commands and such, how do you make a new command in the image.  Do you use something else from open?

Ahhh, I see now. To create a new category, option/alt-click on the parent and there's an option in there somewhere.

As for blocks, I'll find that too now.

Alt-click? How? I've always made categorys using the browser and workspace...

well, that helps some.  thanks.  still really confusing though.  And whenever I mod and save the image, I get this weird glitch where it says "Squeak cannot locate Squeakv2.sources."  And after I click ok, it also comes up with "Squeak cannot locate scratch.changes.  From there, everything works fine, except on startup fill screen mode is always off.  Stupid programs.  Can't wait til 2.0 comes out and blocks can be coded without all this nonsense.

Edit: Alt clicking is just bringing up menus for the browser like it would for a block, and says nothing about new categories.

To define your block, click what you want it in.
If it starts with "message selector and argument names" you are on the right track. If now make sure you are on Instance.
Then use your knowledge of Squeak to define it.

How do you make a mod completely out of scratch?
How would you be able to upload it...?

coolhogs, what you do to mod scratch is shift click the r in the scratch logo in the top left corner and select turn fill screen off.  From there, you click in the resulting gray area, click open, and click browser.  It lets you modify the source code of the program.

Uploading...?
Edit: You have to edit the source code...
It makes it easier to make the mod...
