Question

我为我的游戏获得了这个课程，我想要用CourierNew编写Label高分。 .fnt和.png文件位于assets文件夹中。

angular.module('myApp', ['ngAnimate'])
            .controller("myController",function($scope){


                $scope.toggle =true; 


                $scope.list=[
                {name:'bla',age:28,img: 'https://s3.amazonaws.com/uifaces/faces/twitter/brad_frost/128.jpg'},
                {name:'blabla',age:38,img: 'https://s3.amazonaws.com/uifaces/faces/twitter/mlane/128.jpg'},
                {name:'blaba',age:23, img:'https://s3.amazonaws.com/uifaces/faces/twitter/felipenogs/128.jpg'},
                {name:'blablala',age:56, img:'https://s3.amazonaws.com/uifaces/faces/twitter/adellecharles/128.jpg'}
                ];


                $scope.addPerson= function(){
                    $scope.list.push({name:$scope.name,age:$scope.age});
                    $scope.name="";
                    $scope.age="";
                };
            });

但是我总是得到错误：

        Button.ButtonStyle startButtonStyle = new Button.ButtonStyle();
        startButtonStyle.up = new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("startButtonUp.png"))));
        startButtonStyle.down = new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("startButtonDown.png"))));

        Button.ButtonStyle removeAdsButtonStyle = new Button.ButtonStyle();
        removeAdsButtonStyle.up = new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("removeAdsButtonUp.png"))));
        removeAdsButtonStyle.down = new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("removeAdsButtonDown.png"))));

        CheckBox.CheckBoxStyle muteCheckboxStyle = new CheckBox.CheckBoxStyle();
        muteCheckboxStyle.checkboxOn = new TextureRegionDrawable(new TextureRegion(new Texture("muteCheckboxChecked.png")));
        muteCheckboxStyle.checkboxOff = new TextureRegionDrawable(new TextureRegion(new Texture("muteCheckboxUnchecked.png")));

        Label.LabelStyle highscoreStyle = new Label.LabelStyle(CourierNew, Color.YELLOW);

        String formatted = Integer.toString(score);
        startButton = new Button(startButtonStyle);
        removeAdsButton = new Button(removeAdsButtonStyle);
        muteCheckbox = new CheckBox(null, muteCheckboxStyle);
        highscore = new Label(formatted, highscoreStyle);

        table.add(startButton);
        table.debug();
        stage.addActor(table);


    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(0,0,0,1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        stage.act(delta);
        stage.draw();
    }

    @Override
    public void resize(int width, int height) {

    }

    @Override
    public void pause() {

    }

    @Override
    public void resume() {

    }

    @Override
    public void hide() {

    }

    @Override
    public void dispose() {
        stage.dispose();
    }
}

有什么问题？我已经尝试了很多...希望任何人都可以提供帮助

如果您按照自己发布的追踪信息进行追踪，则会引导您进入

com.badlogic.gdx.scenes.scene2d.ui.Label.setStyle(Label.java:77)

如果您查看code，您会看到（在setStyle方法中）：

if (style.font == null) throw new IllegalArgumentException("Missing LabelStyle font.");

您看到的例外情况。所以问题是初始化Style muteCheckbox（muteCheckboxStyle）的null对象有font作为其＆＃39}。 muteCheckbox = new CheckBox(null, muteCheckboxStyle);。这可以很容易地修复。在致电muteCheckboxStyle初始化font＆＃39; s muteCheckboxStyle.font = CourierNew;：
