json - LibGDX JSON 错误 : JSON standard does not allow identifiers

Question

我复制并粘贴了 uiskin.json 文件以用于 Scene2D UI，但由于某种原因我的代码仍然崩溃。 这是给我错误的 uiskin.json 文件:JSON 标准不允许标识符。它与 default.fnt、uiskin.atlas 和 uiskin.png 一起存储在我的 asset 文件夹中

{
  com.badlogic.gdx.graphics.g2d.BitmapFont: { default-font: { file: default.fnt } },
  com.badlogic.gdx.graphics.Color: {
  green: { a: 1, b: 0, g: 1, r: 0 },
  white: { a: 1, b: 1, g: 1, r: 1 },

  default: { down: default-round-down, up: default-round },
  toggle: { down: default-round-down, checked: default-round-down, up: default-round }
},
  com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle: {
  default: { down: default-round-down, up: default-round, font: default-font, fontColor: white },
  toggle: { down: default-round-down, up: default-round, checked: default-round-down, font: default-font, fontColor: white, downFontColor: red }

    scrollStyle: default,
    listStyle: { font: default-font, selection: default-select-selection }
  }
},
  com.badlogic.gdx.scenes.scene2d.ui.SplitPane$SplitPaneStyle: {
  default-vertical: { handle: default-splitpane-vertical },
  default-horizontal: { handle: default-splitpane }
},
  com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle: {
  default: { titleFont: default-font, background: default-window, titleFontColor: white },

},
  com.badlogic.gdx.scenes.scene2d.ui.ProgressBar$ProgressBarStyle: {
  default-horizontal: { background: default-slider, knob: default-slider-knob },
  default-vertical: { background: default-slider, knob: default-round-large }
},
  com.badlogic.gdx.scenes.scene2d.ui.Slider$SliderStyle: {
  default-horizontal: { background: default-slider, knob: default-slider-knob },
  default-vertical: { background: default-slider, knob: default-round-large }
},
  com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle: {
  default: { font: default-font, fontColor: white }
},
  com.badlogic.gdx.scenes.scene2d.ui.TextField$TextFieldStyle: {
  default: { selection: selection, background: textfield, font: default-font, fontColor: white, cursor: cursor }
},
  com.badlogic.gdx.scenes.scene2d.ui.CheckBox$CheckBoxStyle: {
  default: { checkboxOn: check-on, checkboxOff: check-off, font: default-font, fontColor: white }
},
  com.badlogic.gdx.scenes.scene2d.ui.List$ListStyle: {

  default: { minus: tree-minus, plus: tree-plus, selection: default-select-selection }
},
  com.badlogic.gdx.scenes.scene2d.ui.Tooltip$TooltipStyle: {
  default: {
    label: { font: default-font, fontColor: white },
    background: default-pane
  }
},
}

此外，这是我迄今为止拥有的 Java 代码。只是一个简单的添加按钮，供需要时引用。

public class MyGdxGame extends ApplicationAdapter {
    private Skin skin;
    private TextField username, password;
    private Stage stage;

    @Override
    public void create () {
        skin = new Skin(Gdx.files.internal("uiskin.json"));
        stage = new Stage(new ScreenViewport());

        final TextButton button = new TextButton("Click Me", skin, "default");
        button.setWidth(200);
        button.setHeight(50);

        stage.addActor(button);
        Gdx.input.setInputProcessor(stage);
    }

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

        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
    }
}

工具提示是 libgdx 的一项新功能，它仅存在于夜间构建中，因此您没有它，您可能从 libgdx 的 github 复制了它，您可以检查 here它是 9 天前添加的。我检查了最近安装的 libgdx，如果您尝试导入它，则工具提示不存在。

基本上删除:

com.badlogic.gdx.scenes.scene2d.ui.Tooltip$TooltipStyle: {
  default: {
    label: { font: default-font, fontColor: white },
    background: default-pane
  }
},
