Introducing Scratch
Test your code regularly, to make sure your code does
what you want it to. You will find it much easier to fix
problems in your code if you test each time you make a
change to your code.
Get others to try out your projects, and ask them what
they like about your project and what they would
improve.
You can add comments to a script by right-clicking on a
block and selecting add comment. It’s a good idea to
comment a script to explain what it does, so that others
will know what your scripts do. It’s also useful in case you
forget what your code does!
To delete blocks, drag them
over the palette area. Don’t
worry if you accidentally
delete blocks you need: you
can click the File menu and
then undelete to get them
back!
You can right-click on a block
and choose duplicate to make
a copy of that block and the
blocks attached below it.
