ActionScript 2.0 :: Setting Vars Within Instances Of MovieClip

Mar 15, 2004

I have three mc's that look like cd's Three instances of the same movie clip. They go into a player onRelease. If I click on a cd it looks if any other cd's are clicked. If any of them are clicked then it tells them to gotoAndPlay (thisKeyFrame) in that cd movie clip (which would be a simple tween and will look like the cd comes back out). I tried setting variables in the cdMovie clip like on the first frame onValue="no" but once it goes in and stops the onValue="yes". And then I had AS on each cd looking if the onValue variable is yes or no in each one of them.

Define Vars In Subclasses, Instances?"

Jan 5, 2010

how subclasses, instances, and inheritance work. The below code isn't actual project code, it's theoretical code, generalized to a simplistic level so that we can talk about the big issues. I have animals_app.fla, with a "Dog" class MC and a "Cat" class MC. Both "Dog" and "Cat" are subclasses of "Animals"; animals_app.fla uses document class "Main".

Intuitively,I think Animals should declare that every subclass should have some animalSpecies ,and each subclass will define the value of its own animalSpecies. It wouldn't make sense for Animals to provide any default value, because it will always be different per subclass.Is this correct?

I had tried out some code similar to that below, and was perplexed because it seemed like whenever a subclass tried to define a value for its own animalSpecies variable, it was actually changing the value of the variable in the Animal class, but that's not what I want. How do I rewrite this code so that each subclass defines the values of variables it inherits from its superclass, without altering the superclass? And how would I define the value of variables for each instance of a class, so that I'm only changing the values of that instance, without altering the subclass?

Animals.as
package
{import flash.display.MovieClip;[code]..........

Also, conventionally, what should be in my Main class? Only the addChild code which attaches MCs to the stage? Or should the values of variables be defined in Main? What am I missing?I recently read Foundation Game Design with Flash and didn't feel like the explanation was sufficient.

I recently read Foundation Game Design with Flash and didn't feel like the explanation was sufficient. I've tried scouring the web for OOP tutorials, but they're either too basic or too far over my head. Can someone please explain where I should be defining values of variables for classes, subclasses, and instances?
