Question

我发现了一些关于这个话题的类似问题，但没有人帮助过我。我从Github下载了“uiskin.xxx”和“default.fnt”文件，用一些测试资产开始游戏，但是uiskin.json文件似乎有问题。所有文件都在android / assets / Skins文件夹中。

这是加载json文件的代码：

public class Assets {
public static AssetManager manager = new AssetManager();
public static Skin menuSkin;

public static void queueLoading() {

    manager.load("Skins/uiskin.atlas", TextureAtlas.class);
    manager.load("Ressources/DemonHunter.jpg", Texture.class);
    manager.load("Ressources/DemonWarrior.jpg", Texture.class);
    manager.load("Ressources/WingedDemon.jpg", Texture.class);
    manager.load("Ressources/Viking.jpg", Texture.class);

}

public static void setMenuSkin() {

    if (menuSkin == null)
        menuSkin = new Skin(Gdx.files.internal("Skins/uiskin.json"),
                manager.get("Skins/uiskin.atlas", TextureAtlas.class));

}

public static boolean update() {
    return manager.update();
}
}

这是json文件：

    }
},
}

我不确定开头的路径是否正确，但我尝试了一些不同的路径以确保这不是错误。

这是错误：

谢谢你的每一个答案:)。干杯，Joshflux

Answer 1

正如James Skemp在评论中所建议的那样，在IDE中打开uiskin.json文件并从中删除以下行或类似文件并保存文件：

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

现在它应该可以正常工作。我不知道它为什么会起作用。

你有地图集文件吗？如果没有，你应该。它们的用法如下：

    FileHandle fileHandle = Gdx.files.internal("pathToMyJsonFile/fileNameForMyJson.json");
    FileHandle atlasFile = fileHandle.sibling("fileNameForMyJson.atlas");
    if (atlasFile.exists()) {
        Gdx.app.log("MyGame", "atlas file is loaded");
        skin.addRegions(new TextureAtlas(atlasFile));
    } else {
        Gdx.app.log("MyGame", "atlas file is NOT loaded");
    }

Atlas文件在png文件中定义纹理的位置。您可以找到API for TextureAtlas here。

在json文件中，有一个对default-pane的引用。那里定义了 NOT 。 Atlas文件是应该定义的地方。

我希望它有所帮助。 =]
