Where do I put the initialize "script" #initialize is not a script, it's a method. When an object is instantiated (for ex with: MyObject new) #initialize is automatically sent to it. This is the place to put your newly created object in a correct initial state. In your class, you just define a protocol named for example "initialization" where you put all the initialization-related methods. Note that protocols have no meaning, i.e. they don't change how your objects behave, they're just here to help you classify the methods of a class by concerns. So the tutorial tell you to create two methods: #initialize that is automatically called after an object has been instantiated and #initializeActiveSegments where you put some other initialization logic, that's all. When I put it on the initializeActiveSegments then initialize get not found. Sorry, I don't understand. Or must I make a seperate protocol named ActiveSegments for it. No use the same protocol "initialization" or "initialize-release" or whatever. Oke, I changed it so I have this : Laser-Game-Model with as classes:  - BlankCell  - Grid  - MirrorCell  -TargetCell BlankCell has the following protocols: - initializing-release - testing Initializing - release contains the following  methods: - initialize - initializeActiveSegments testing contains the following methods: isOn isOff but when I run the test-runner I see this : MessageNotUnderstood : BlankCell >> activeSegments. This error means "instances of BlankCell does not understand the message #activeSegments" that's all, this part of your program is not implemented yet.  Im not agree with you according to the tutorial  on this page : http://squeak.preeminent.org/tut2007/html/019.html there is a error with isOn and isOff. #activeSegments schould be implemented by now.
