Scratch

I believe this one of the features in the next version.

As no one answered, I digged the code myself and found that you can change the default sprite by hard-coding its name into the startup code (I'm a real newbie at SmallTalk and Squeak, so as I couldn't find where the current default sprite name is hard-coded, I just found a place where I could hard-code it myself).

If someone wants to try it themselves, you can follow the general istructions on how to work on Scratch's source code at http://scratch.mit.edu/forums/viewtopic.php?pid=50005#p50005 and then, instead of doing the step "create a new block by defining a command spec", do the following:

1. In the System Browser, with "instance" selected, look for Scratch-UI-Panes > ScratchFrameMorph > initialization > startup
2. go down the "startup" method and replace the following lines

    fileName <- startupFileNames
        detect: [:fn | fn asLowercase endsWith: '.sprite']
        ifNone: [^ self].

with

    fileName <- 'turtle.sprite'.

In this example I suppose that my new default sprite is named "turtle.sprite" and it is in the same folder than the source code. Have fun customizing Scratch as you like!

Hmmm, great tip. I have no reason to want to change the default sprite, but sometimes I'd like start up with a completely blank project.

Thanks. I would like to know much more about Scartch's source code, even a general explanation about how the code is organized would be very useful to me. But maybe I'm not getting the most from the code as I don't know much of how SmallTalk programmers usually organize their code.
