I have an integer "score" defined in the class Player. How do I get this integer in another class?

How do I get access to a variable in another class?
If it is a private int, then you need a getter method:
If there is only one Player object in the world, then you can get the score in another class like this:
1 2 3 4 | public int getScore(){ return score;} |
1 2 3 4 5 | //in an Actor subclass in the same worldint playerScore = ((Player)(getWorld().getObjects(Player.class).get(0)).getScore();//in the World subclass in which the player is inint playerScore = ((Player)(getObjects(Player.class).get(0)).getScore(); |
Thank you for your quick reply. I need int "score" in the class "ScoreBoard".
So I copied your code and put
into the class "Player". Then I put
into the class "ScoreBoard", and
into the World subclass ("MyWorld" in this case). So Greenfoot says that at the end of your code a ")" is missing, so it should be ".getScore())". But then these brackets get underlined and the error report says: "incompatible types: int cannot be converted to Player." What can I do?
1 2 3 4 | public int getScore(){ return score;} |
1 2 | //in an Actor subclass in the same worldint playerScore = ((Player)(getWorld().getObjects(Player.class).get(0)).getScore(); |
1 2 | //in the World subclass in which the player is inint playerScore = ((Player)(getObjects(Player.class).get(0)).getScore(); |
The ) is missing after the get(0)), another ) has to be added after that.
The code was an example what you have to do to get the value of the score field. The line itself doesn't do anything.
