Hello,
Hello,
Im on this page now: http://squeak.preeminent.org/tut2007/html/017.html
I do not understand one thing.
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.
