◄Hidden Feature► Cloning Sprites in Flash Player

I just discovered that there are two hidden blocks in the flash player. If you make a block with the selector 'createClone' and run it in the flash player, it will create a clone of that sprite! The selector 'deleteClone' deletes the sprite it runs in. I made an example here.

To make the cloning blocks in Scratch, you need to add two blocks called 'clone me' and 'delete me' to the sprite blockspecs. Here is a tutorial on installing block.

http://img845.imageshack.us/img845/6443/cloneme.gif

Code:

Blockspec:
('clone me' #- #createClone)

Code:
createClone
    | t2 t3 |
    t2 _ self ownerThatIsA: ScratchFrameMorph.
    t2 ifNil: [t2 _ (self ownerThatIsA: OffscreenWorldMorph) frame].
    t2 ifNil: [^ self].
    t3 _ self fullCopy.
    t3 objName: objName , ' clone'.
    t3 isClone: true.
    t3 blocksBin
        allMorphsDo: [:t4 | (t4 isKindOf: BlockMorph)
                ifTrue: [t4 stop]].
    t2 workPane addMorph: t3

http://img209.imageshack.us/img209/6596/deleteme.gif

Code:

Blockspec:
('delete me' #- #deleteClone) 

Code:
deleteClone
    self undoableDeleteSprite

There is also a hat block that is called when a clone is created and it's selector is 'whenCloned' and I am to lazy to create code for it ATM. Feel free to donate some code if you want.  tongue

Looks like the Flash Player slows down after about 50 clones. Nice find!

Can you give me the link to where you found the flash source?

You never know, maybe the Scratch Team purposely left it in there so we could find it and use it to our advantage.  wink

It's said that we can only use this until the team finds out.
I wish they'd keep it...  sad

Yeah, maybe they're preparing the player for 2.0!
(Duh, they're making the player because of 2.0. xP)

I'm 80% sure they will remove the feature/disable it.

Anyhow, how do you explain this?

Looks like both the main and the cloned sprites are moving so they stay on top of each other.

Ah... that could be a problem. However I made a script for that purpose on purpose!
Never mind -- works now. Epic find!

Re: ◄Hidden Feature► Cloning Sprites in Flash Player

How did you find this? Did you decompile the Flash player? Can you post a link to the decompiled source?

Sadly, no.  sad  I have a trial version of an SWF decompiler and cannot export anything.

Re: ◄Hidden Feature► Cloning Sprites in Flash Player

On the project.you asked me how I knew about this. Look at the forum new mod development, I bumped it for you  wink

If you are reading this, please read to the end, because if you don't you won't know what's at the end. Don't just skip to the end though otherwise you won't be able to read the middle, which is most important. Now you must be wondering why you just read all that, the reason is you may have not noticed something, read it again and see if you notice it this time  smile
