JAVA程序
我最近开始使用LibGDX制作“ Pacman”的简单克隆。但是,我在将文本文件加载到扫描仪时遇到问题。当我在NetBeans中运行我的游戏时,一切都很好。但是问题出在我尝试将其作为.jar文件运行时。
我曾尝试使用BufferedReader,FileReader,但没有一个解决了问题...
File subor = Gdx.files.internal("HraciaPlocha/gamearea.txt").file();
Scanner sc = new Scanner(subor);
this.width = sc.nextInt() + 1; // Custom width
this.height = sc.nextInt() + 1; //Custom height
sc.nextLine();
this.arena = new Block[width][height];
for (int rows = 0; rows < this.arena.length - 1; rows++) {
for (int columns = 0; columns < this.arena[rows].length - 1; columns++) {
switch (sc.nextInt()) {
case 1:
this.arena[rows][columns] = new Bariera(lavaXSur + 32 * columns, hornaYSur + 32 * rows);
break;
case 2:
this.arena[rows][columns] = new KlasickaBodka(lavaXSur + 32 * columns, hornaYSur + 32 * riadky);
this.pridajBodku();
break;
case 3:
this.arena[rows]columns] = new Zmurzuvac(lavaXSur + 32 * columns, hornaYSur + 32 * rows);
break;
default:
this.arena[rows][columns] = null;
break;
}
}
}
sc.close();
this.spustena = true;
}
我希望从.jar文件运行时游戏能够运行,但它会给我这个错误:

如果您能帮助我解决这个问题,我将非常高兴。
PS。如果不清楚,请提出要求。 :)

我尝试过与您相同的操作,并且出现相同的错误。
我不确定为什么会出现错误,但是我解决了这样的问题:
FileHandle f = Gdx.files.internal("test/test.txt");
Scanner scanner = new Scanner(f.read());
while(scanner.hasNext()){
System.out.println(scanner.nextLine());
}
