Я делаю простую текстовую игру, где вам нужно вводить команды для предварительной обработки определенных действий. Недавно я добавил в игру функцию, которая позволяет вам сохранить ваш прогресс. Но по какой-то причине, если вы попытаетесь сохранить игру над существующим файлом сохранения, он сработает. Вот код, который сохраняет игру (, когда не спасти он говорит: «Был ошибка при попытке сохранить данные игры Игра будет закрыта..», Как ожидается,):Сбой программы Java при перезаписывании существующего .txt-файла?
import java.util.Formatter;
import javax.swing.JOptionPane;
public class Gamesave {
private static Formatter gamesave;
private static Formatter firstTimeSave;
private static Formatter attackpoints;
private static Formatter defensepoints;
private static Formatter skillpoints;
private static Formatter wins;
private static Formatter loses;
private static Formatter money;
// Attackpoints, defensepoints, skillpoints, wins, loses, money
public static void openFile(){
try{
attackpoints = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_attackpoints.txt");
defensepoints = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_defensepoints.txt");
skillpoints = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_skillpoints.txt");
wins = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_wins.txt");
loses = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_loses.txt");
money = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+"_money.txt");
gamesave = new Formatter("c:\\FightNight\\Saves\\"+MainClass.newProfileName+"\\"+MainClass.newProfileName+".txt");
firstTimeSave = new Formatter("c:\\FightNight\\Game Data\\firstTimeSave.txt");
}catch (Exception e) {JOptionPane.showMessageDialog(null, "There was an error when trying to save game data. The game will now close."); System.exit(0);}
}
public static void addRecords(){
attackpoints.format("%s",MainClass.attackpoints);
defensepoints.format("%s",MainClass.defensepoints);
skillpoints.format("%s",MainClass.skillpoints);
wins.format("%s",MainClass.wins);
loses.format("%s",MainClass.loses);
money.format("%s",MainClass.money);
firstTimeSave.format("%b", MainClass.firstTime);
}
public void closeFile(){
attackpoints.close();
defensepoints.close();
skillpoints.close();
wins.close();
loses.close();
money.close();
gamesave.close();
firstTimeSave.close();
}
}
Вот код, который вызывает классы:
static class SaveAction implements ActionListener{
public void actionPerformed (ActionEvent e){
try{
Gamesave.openFile();
Gamesave.addRecords();
save.closeFile();
JOptionPane.showMessageDialog(null, "Your game has been saved.");
}catch (Exception e1) {JOptionPane.showMessageDialog(null, "Sorry, that is an invalid response.");}
}
}
Еще одно замечание, когда игра запускается в первый раз на компьютере, он создает каталоги для сохранения файлов и что-нибудь еще нужны. Благодарим за помощь!
