Ich mache ein Text-basiertes Spiel mit Java, aber ich lief auf ein Problem.Ich bekomme immer eine Init-Ausnahme in meiner Klasse
Ich habe die erste Klasse „Game“ und die zweite Klasse „ForestEvents“ Ich versuche in der Spielklasse eine Methode (Stadttor) von der ForestEvents Klasse zu rufen, während auf Variablen aus der Spielklasse beziehen()
public class Game

die zweite Klasse
public class ForestEvents extends Game
{
public void townGate()
{
position = "towngate";
mainTextArea.setText("You are at the gates of the town. A guard is standing in front of you. What do you do?");
choice1.setText("Talk to the Guard");
choice2.setText("Attack the Guard");
choice3.setText("Leave");
choice4.setText("");
}
}
Aber immer, wenn ich das Programm laufen bekomme ich eine Ausnahme, die sagt:
Exception in thread "main" java.lang.StackOverflowError
bei ForestEvents. (ForestEvents.java:2)
am Spiel. (Game.java:23)
Was ich bin Versuchen zu tun ist die Methoden in der 1. Klasse zu nennen und sie in der 2md Klasse zu machen, also wenn ich mehr Methoden in der 2. Klasse hinzufüge, werden sie leichter zu verwalten sein als alles in der 1. Klasse.
Meine Frage ist, wie repariere ich die Ausnahme? Oder gibt es einen effizienteren Weg, dies zu tun?
