RE: TUT on game

When you select the Laser-Game-Model category, you see a class
creation template on the bottom pane of the Browser. Fill it out
as shown, then right-click and press "accept" (or press the
keystroke alt-s/cmd-s, depending on platform)

I am CC'ing this to Stephan; Stephan, could you add these
instructions to page

Great I got the message on how to do the subclass but how do you create a new protocol?  tests etc etc In the tut on game.

Sorry if I am a pain but I would real like to learn this and the game tut is got me very interested.  Any help is great

Chuck

Your comments are very useful. After a while, one forgets what
it is like to be new to something. Thanks for reminding us. Here
is my addition to the tutorial that answers your question. It is
meant to go in between the two images at
http://squeak.preeminent.org/tut2007/html/015A.html

To help keep classes organized, Squeak provides method
categories for each class. Method categories are sometimes
called protocols. Create a new protoocol called tests.
Right-click on the third pane (the protocol list), and select
<i> New Category -> new... </i> Enter the name "tests":

Now, create a method called testCellOnState. Like with class
creation and editing, we do this by editing the code in the
lower pane:

Stephan: could you add this to the tutorial?  I had named the
screenshot 042A.jpg in keeping with your naming convention, but
imageshack changed it.
