Scratch

Text-Based Scratch would be good for some people who can code outside of scratch, like I know some Visual C#

Text-based Scratch. This is how I think it might look.

[replaceItem( )of"    "with"    "]

(item( )of"    ")
(lengthOf"    ")
<"    "contains"    ">

Sample Script:

firstly: if scripts are not loops. if anything, the text based version of scratch should have ^end if^ awell as ^end loop^.
secondly: you made a syntax error when you were translating the blocks mode to text mode. you missed out a ^. check your code again!

You're right, this isn't Java. But I was thinking about Scratch spin-off which could be object oriented... Take look at this code:

>When I receive : moveParticles<
  [set "particles number" to (number of "particle" class members)]
  [set "iterator" to 1]
  [repeat until <(iterator) = (particles number)>] {
    [(join "Particle" (iter)] [glide (pick random 0.1 to 0.4) secs to x (pick random (stage:x_min) to (stage:x_max) y (pick random (stage:y_min) to (stage:y_max)]
    [change "iterator" by 1]
  }

1. Whats wrong with { and } ?
2. Object-oriented programming was in Scratch - version 0.1

I can see where this would be very handy as a transition to other text-based languages.  I don't know how hard it would be to implement though.  I know Jens wrote a method of extracting scripts to text - that's half the battle

I'd love to see OOL in scratch? do you still have the image file?

Thats it! lets all switch to chirp and learn his XML version!

for if. it should be ^end if^ instead of ^end loop^

There is no block substitute. Illegal cammand.

Well... I guess for people that are used to text-based languages to use scratch as a text-based languages. I don't know...

The thing that i would like Scratch Developers to keep in mind ( When ) they get around to implementing something like this...
Is to Keep The -Plain Text- Version as Easy to Use as The Brick Version...!
That is: Try to make the Plain Text Version Very Close To Plain English ( et. al. )
And NOT NOT NOT NOT NOT NOT NOT Like All The Other -Conventional- Programming Languages...!!!
This is actually very easy to do with something like RPL which has NONE of The Crazy Punctuation Marks that you see in most languages.
RPL has Reserved Words, and Reserved Variable Names, And it just executes Designated Commands when it comes to them.

IF Variable = 0 THEN BROADCAST LemonCookie
MOVE 16 STEPS
TURN CLOCKWISE 14 DEGREES
TURN COUNTERCLOCKWISE 2.4 RADIANS
IS SPRITE Muffin TOUCHING THE COLOR CherryRed

It Might also be Nice to be Able to Define Colors And Give them Names...?
CherryRed IS THE COLOR 12, 33, 66
Defined in HTML Code ( or whatever ??? )

SET Parakeet AS THE ANGLE IN DEGREES BETWEEN THE SPRITE Qbert AND Henry

IF Strawberry IS LESS THAN AppleTime THEN BROADCAST ZooFactory

i've always had a problem with The Change Commands...
And would like to CHANGE THEM...

ADD 12 TO Elephant
MULTIPLE Zebra BY 4
DIVIDE EarthWorm By 3
SUBTRACT 5 FROM  X-AXIS

Please Keep Scratch SIMPLE...!!!

Once I learn flash, I might make an only Text-Scratch (blocks not available), and give lots of credit to you 

lol was that sarcastic? It seemed like it.

I think this will be easy to learn because we could use the same code we use for the forum blocks. Like this:

<say[ it works!

And now:

NOT Code:


<say[ it works!

I used the same code each time. So, we could just use the forum commands.

Why don't we just make one are selves? I'm learning Python, if you have any other idea for a programming language that doesn't require Admin privs or that takes a lot of space. (Less than 25 meg) I could work with that.    And someone, if they're nice enough, could make a site to upload the projects. ^.^
