Scratch

This is where M30W started... With the say and ask commands. xD

I suggest looking at M30W. It's a Python version of Scratch. http://scratch.mit.edu/forums/viewtopic.php?id=106225 I'm sure Roijac wouldn't mind another developer.

What's PyGame? I'm *really* new to Python.

An extension to Python allowing the creation of games and GUI applications. I have quite a bit of experience with it. 

Okay. Yeah, I'd be happy to combine projects with you! So does your project read Scratch projects and convert them to PyGame, or do you just use Scratch-like commands and convert those to PyGame?

I'm still in the early stages of my project, so I don't really know if it's going to turn out exactly the way I want it to, but I want it to basically define all of the blocks and simulate the Scratch project player. The hard part is going to be scripting the conversion from .sb to .py, but maybe we can take some example from Kurt. Sound OK?

Sure. So we'll basically map Scratch blocks to Python functions? We should also let the user program in PyScratch (the Python functions).

Yep. 

Good idea! We can write PyScratch as a module, and Scratch2Py to convert in between PyScratch and sb. Epic! 

The hard part (besides the sb file format) is simulating Scratch: having multiple scripts running at once. I would use a class for each sprite, and a global cue. I have no clue whether it will work or not, though. 

XD I have no clue either.
I'll start working on the non-visual Scratch blocks, and if you want, you could work on the visual blocks.
Should we keep calling it PyScratch?

Okay, cool! What exactly do you mean by "visual"?

And yeah, PyScratch sounds epic. 

GUI-type stuff. (i.e. sprite movement, pen, looks, etc.)
Thanks!

I'd like to use scratch.py for broadcasts, does that work for you?
Also, we probably need to change the name since this I'd kind of a mod of Scratch.
Maybe some type of pie (py)?

so are you making a python .sb viewer or a scratch like pygame framework?

if you're doing .sb viewer, id really appreciate if you'd come over to M30W, the editing is already working, only executing projects is left 

Here's a list of names I've come up with:
CherryPy
ICanHazPy
EasyAsPy

(800th post!)

Hey techno, I think this little code might work. It doesn't run yet, but you can see the concept, right?

Sprites = []
Scripts = []
Blocks = []
Cue = []
class Sprite():
    global Sprites, Scripts
    x = 0
    y = 0
    dir = 90
    hidden = False
    myScripts = []
    name = "Sprite1"
class Script():
    global Sprites, Scripts, Blocks
    id = 0
    myBlocks = []
    pos = 0
    owner = 0
    def __init__(self):    
        global Sprites
        k = 0
        for i in Sprites:
            for j in i.myScripts:
                if j.id == self.id:
                    self.owner = k
            k += 1
class Block():
    global Scripts, Blocks, Cue
    id = 0
    block = 0
    inputs = []
    complete = False
    running = False
    owner = 0
    def __init__(self):
        global Scripts
        k = 0
        for i in Scripts:
            for j in i.myBlocks:
                if j.id == self.id:
                    self.owner = k
            k += 1
    def check(self):
        global Scripts
        if self.running == False:
            Scripts[self.owner].pos += 1
            if (Scripts[self.owner].pos + 1) > len(Scripts[self.owner].myBlocks):
                Scripts[self.owner].pos = -1
    def run(self):
        global Sprites, Cue
        #All of the block definitions go here.

dont wanna be offensive, but assigning instance attributes at class level isnt gonna help you a lot

Any suggestions?

When you assign attributes in python you usually do this:

Code:

class Object:
    def __init__(self):
        self.foo = None
        self.baz = None

Oh, I'll do it like that then.

Also, I don't think that the cue is necessary; we'll see later.
