Hey guys, I have a space invaders type game pretty much done but i'm trying to limit the amount of player bullets on screen to 5.

Player (the ship) and Bullet are two seperate sub-classes of Actor and I want an int in the Player class to be updated in a method in the Bullet class.

It just wont seem to work.

I have within a method in Bullet a part that removes the bullet when it goes off-screen (y < 0) and it is here that i want to change an int in the Player class.

Then I want the int to be used again in the player class.

If i havent made any sense i could post the code as well.

You are not making much sense, please post your code.

basically, as far as I understand it, what you want is something this:

class SomethingA {
   private int myInt;

   public int getMyInt() {
       return myInt;

   public void setMyInt(int newInt) {
       this.myInt = newInt;
class SomethingB {
   private SomethingA myReferenceToTheOtherClass;

   public SomethingB(SomethingA other) {
      // lets change something in the other class!
     this.myReferenceToTheOtherClass = other;

     this.myReferenceToTheOtherClass.setMyInt(666); // hah! 666 is evil
