As is mentioned on the Create Clone of () (block) article, classes are like clones in Scratch. There is the class, and there are instances of the class, which are things with the class's info and added info of their own.
Creating a Class
One can start creating a class with the
class keyword, like so:
class Book end
Next, the class should have an initialize method. This can be created like so:
class Book def initialize end end
But, what about the differences between instances of this class? The class needs parameters.
class Book(title, age_group, genre) def initialize end end
When the parameters for an instance of the class are known, the class should have those parameters in a variable specific to the instance of the class.
class Book(title, age_group, genre) def initialize @title = title # Variables beginning with "@" are specific to a certain instance of a class. @age_group = age_group # Here, the variables are being set to whatever the parameters were set to. @genre = genre end end
