Question

public class Game {

    public Game(
        boolean createstage, //For sorting purposes
        int slength, 
        int sheight, 
        boolean createplayer, 
        int plength, 
        int pheight, 
        boolean playersprite,
        BufferedImage psprite, 
        boolean defaultcontrols,
        String pcontrols, 
        boolean test
        ) {
    if(test == true) { //if test is true, test
        new Test();
    }else{ //otherwise create a stage is createstage is true and
        if(createstage == true) {
            StageObj gamestage = new StageObj(slength, sheight);
        }
        if(createplayer==true) {
            PlayerObj player = new PlayerObj(plength, pheight, psprite, pcontrols);
        }
    }
}

public Game() {
    new StageObj(100, 100);
    new PlayerObj(10, 10);
}

public StageObj givestageobj() {
    return gamestage;
}

public PlayerObj giveplayerobj() {
    return player;
}

}

So goes the code of my constructor and two variables designed to return the variables created in the constructor. The problem is that the method giveplayerobj and givestageobj both don’t find the variables gamestage and player. This makes sense, but how do I create the variables in the constructor and then somehow pass them to the giveplayerobj() and the givestageobj() variables so someone could theoretically go Game.giveplayerobj() which returns the playerobj created in the constructor?

Thanks

You need to declare them as class attributes and not inside the constructor for that to work. So, you code should look like what is shown below.

Changes:

1. I have added two class variables StageObj andPlayerObj because you have getters for them in place.
2. Removed the declaration of these two variables from inside the constructor.

3. Added assignment to the overidden default constructor. (Probably what you were trying to achieve with the default constructor)

   public class Game {
   
   private StageObj gamestage = null;
   private PlayerObj player = null;
   
   public Game(
       boolean createstage, //For sorting purposes
       int slength, 
       int sheight, 
       boolean createplayer, 
       int plength, 
       int pheight, 
       boolean playersprite,
       BufferedImage psprite, 
       boolean defaultcontrols,
       String pcontrols, 
       boolean test
       ) {
   if(test == true) { //if test is true, test
       new Test();
   }else{ //otherwise create a stage is createstage is true and
       if(createstage == true) {
           gamestage = new StageObj(slength, sheight);
       }
       if(createplayer==true) {
           player = new PlayerObj(plength, pheight, psprite, pcontrols);
       }
   }
   }
   
   public Game() {
       gamestage = new StageObj(100, 100);
       player = new PlayerObj(10, 10);
   }
   
   public StageObj givestageobj() {
       return gamestage;
   }
   
   public PlayerObj giveplayerobj() {
       return player;
   }
   
   }
