Join Todd Perkins for an in-depth discussion in this video Defining properties and methods, part of Flash CS4 Professional: Object-Oriented Programming .
In this movie, we'll look at defining properties and methods for our…SimpleClass. I'm going to jump over to SimpleClass2.as, which is actually just…a skeleton of the class. So I have the name SimpleClass2 and the constructor is…called SimpleClass2 as well.…So let's look at properties first. So I'm going to create a new public property…by typing the word public var. So remember, properties are just variables that…are attached to a class. Now let's give this a value of simpleProp, data type…this to a String, and we won't give it a value yet.…
Now here the public keyword just means we can access this variable or property,…rather, from the main Timeline in our FLA file. Again, we'll talk more about…these access modifiers in another movie.…So let's give that a value inside of the constructor method. Anything that's a…property should receive its value somewhere besides above the constructor. This…is because any objects that you are referring to inside of your code don't…exist until the constructor runs. So above the constructor is the best place to…
