Accessing stage objects from other objects

Question

I have drawn colored rods which I have placed in the library and have put one of each on the stage with instance names like
blueRod_mc, etc.
I place them around with time-line code like
blueRod_mc.x = 300.0;
I have now created an Actionscript class called Problem.
I build a new object from Problem which I have called Riddle.
But when I put blueRod_mc.x = 300.0 in a method (of Problem),
I get the message that blueRod is not accessible.
So I tried
stage.blueRod_mc.x = 300.0;
That did not work either.
What does work? How can I modify properties of stage objects like blueRod from
within an AC3 object like Riddle?

Answer 1

public class Problem {
  private var number1:String ="";
  private var number2:String ="";
  private var rigor:Number = 1;
     // rigor: -1 is 3 steps, -2 is 4-5 steps, -3 is 6-7 steps
  private var step:Number = 1;
  private var numSteps:Number = 3;
  private var solving:Number = 0;
  private var true1Length:Number;
  private var true2Length:Number;
  private var tuple = new Array(6);
  public function Problem():void  {
   // constructor code
   var i:Number;
   var j:Number;
   for (i = 0; i < 6; i++) {
                 tuple[i] = new Array(3+5);
                 for (j=0; j < 3; j++) {
                   tuple[i][j] = new Array(8+7);
   buildIt();
   planIt();
Just insert bolded code where you need to.
