Scratch

Wait... The only problem with custom blocks is that you cannot use them in a project you plan to share. It needs some javascript code to go with it, otherwise Java won't know how to handle the new block. Great tutorial, anyway.

I am using almost all of these blocks in my new mod, Peak. You (LS97) will be the first person on the contributers list.

If you wait a bit you can mod Blocks++

If you make a mistake when coding a custom block and when try to use block it causes an error, all of your other custom blocks (but none of the normal ones) stop working and you have to restart Scratch. It's really annoying, so can anybody tell me why it does this? Also, why is it only the other custom blocks that jam up, not the normal ones?

^ I get that in CYOB but it stops all Panther blocks!

ill make it now!

or just

    | t1 |
    (t1 _ self ownerThatIsA: ScratchStageMorph) ifNil: [^ false].
    ^ (self containsPoint: t1 adjustedCursorPoint)
        & Sensor anyButtonPressed

For the [say () until <>] use

[say ()]
[wait until <>]

Thanks for this tutorial. It has helped somewhat. So far, I'm able to read and understand little, aswell as easily create the blocks that you've guided us through. I have a desire for this certain block, since it will greatly improve the game I am working on. I would like to know how to add, "Replace [thing] of [List] with [thing]". I haven't surfed through all thirty-three pages of this thread, so if I missed anything important, like you're not taking suggestions anymore, then my bad.

Oh well I was bored so I made it anyway:
Name:
replace item %s of %L with %s

Type:
-

Block Spec:
('replace item %s of %L with %s'         #-      #replace:list:with: 'hi' 'list' 'hello')

replace: t1 list: t2 with: t3

| t4 t5 t6 t7|
t7_ 0.
t4_ 0.
t5_ self lineCountOfList: (t2).
t6_ ''.

t5 timesRepeat: [
t7_ t7 + 1.
t4_ self getLine: (t7) ofList: (t2).
t4 = t1
ifTrue: [

t6_ t7.
].
].
t6 = ''
ifTrue: [
t6_0.
]
ifFalse:[
t6_ t6.
self setLine: (t6) ofList: (t2) to: (t3). 
].

EDIT:
You may use the block in a mod but give credit to JD or JD1.

Why not just

self setLine: ((self listNamed: t2 ifNone: [^ self]) listContents indexOf: t1 ifAbsent: [^ self]) ofList: t2 to: t3

You don't need to give any credit for this one; and it's faster.

Well, that code is completely legit, so I guess you'll just have to try again.

The 'save stagearea to sprite' block
http://www.freeimagehosting.net/uploads/c8267d9caf.gif
I did this one on request of SeptimusHeap. it's maybe the easiest of the blocks. No coding needed, just add the block to the blockSpecs in ScratchSpriteMorph:

Code:

 ('save stage area to sprite' #- #grabFromScreen)

that's it! easy right?
PS. in case you didnt know, you have click accept.

Thanks for this too!
