How to access Number through separate class?

Question

Hey everyone so this is something that I have always had trouble trying to accomplish or understand. So I have my main Engine class calledescapeEngine where I have a private var nScore I want to be able to access this variables through a separate class called mcPlanets but I don't know how I would accomplish this. I know how to do the opposite but not how to access a var from my main Engine class. Can anyone help me out?

Answer 1

I am not sure what you are trying to do, but here is an example that may help you:

Inside esacapeEngine class (main), create a public var nString and new instance of mcPlanets.

// two lines in escapeEngine.as
var nScore = 0;
var mcPlant = new mcPlanets(this);   

So, when you create new mcPlanets, pass in the reference (keyword 'this' in the parentheses). Now mcPlanets knows about your main class.

And now in mcPlanets class, write this:

public class mcPlanets 
{
    private var escapeEngine;

    public function mcPlanets(main)  // 'this' = 'main'
    {
        escapeEngine = main;

        // access nScore defined in main class
        escapeEngine.nScore = 5;
    }
}

In this example, nScore must be a public variable, it could be a private but you should use 'get and set' methods.
