Question

我已经开始在Libgdx开发游戏，我开始研究某些东西。我有一个background.png我试图从我的皮肤加载。我正在尝试将gameskin.atlas加载到我的AssetManager对象中，但每次我尝试加载它时，都会收到一条错误消息：

Caused by: com.badlogic.gdx.utils.SerializationException: Error parsing file: packs/gameskin.atlas
    at com.badlogic.gdx.utils.JsonReader.parse(JsonReader.java:77)
    at com.badlogic.gdx.utils.Json.fromJson(Json.java:692)

这是我尝试加载它的地方：

package screens;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.scenes.scene2d.ui.Image;
import com.badlogic.gdx.scenes.scene2d.ui.Skin;

import engine.Values;


public class GameScreen extends ScreenWrapper{

    private final String GAME_SKIN_PATH = "packs/gameskin.atlas";
    private ScreenRenderer renderer;
    public GameScreen(ScreenManager manager) {
        super(manager);
    }

    @Override
    public void initiate() {
        manager.getLoader().load(GAME_SKIN_PATH, Skin.class);
    }

    @Override
    public void buildStage() {
        Skin skin = manager.getLoader().getAsset(GAME_SKIN_PATH, Skin.class);
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(242/255f, 242/255f, 242/255f, 0);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        super.render(delta);
    }

    @Override
    public void dispose() {
        manager.getLoader().unload(GAME_SKIN_PATH);
    }

}

我试图删除gameskin.atlas文件中的size参数，但这不是问题。可能是什么问题？

编辑：我尝试使用AssetDescriptors和SkinParameter来解决这个问题。现在它发出了这个错误：

这是我的GameScreen Now：

package screens;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.scenes.scene2d.ui.Image;
import com.badlogic.gdx.scenes.scene2d.ui.Skin;

import engine.Values;
import engine.utils.AssetsLoader;


public class GameScreen extends ScreenWrapper{

    private ScreenRenderer renderer;
    // The constructor gets the ScreenManager to notify on screen transitions
    public GameScreen(ScreenManager manager) {
        super(manager);
    }

    @Override
    public void initiate() {
        manager.getLoader().load(AssetsLoader.SKIN_GAME);
    }

    @Override
    public void buildStage() {
        Skin skin = manager.getLoader().findAsset(AssetsLoader.SKIN_GAME);
        Image backgroundPitch = new Image(skin.getDrawable("football_pitch"));
        backgroundPitch.setSize(Values.WIDTH, Values.HEIGHT);
        renderer.addActor(backgroundPitch);
        addActor(renderer);
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(242/255f, 242/255f, 242/255f, 0);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        super.render(delta);
    }

    @Override
    public void dispose() {
        manager.getLoader().unload(Values.GAME_SKIN_PATH);
    }

}

您正在尝试将Atlas加载到Skin。 Atlas是保存图像的所有打包数据的文件。 Skin保存要与Scene2D，BitmapFont和LabelStyle等ButtonStyle元素一起使用的数据。

皮肤需要json 皮肤文件和图册。要使用AssetManager一次性正确加载，您需要使用SkinLoader.SkinParameter。

manager.load("skin.json", Skin.class, new SkinLoader.SkinParameter("image.atlas"));

此外，我更喜欢使用AssetDescriptors在经理中查找资产。这些将进入您的经理班：

//A atlas or texture do not require additional parameters.
public static final AssetDescriptor<TextureAtlas> ATLAS = 
    new AssetDescriptor<TextureAtlas>("image.atlas", TextureAtlas.class);

//A skin does require additional parameters.
public static final AssetDescriptor<Skin> SKIN = 
    new AssetDescriptor<Skin>("skin.json", Skin.class, 
    new SkinLoader.SkinParameter("image.atlas"));

现在加载这些/你想要manager.load(skin)。当您需要特定资产时，您可以在Assets类中静态查看这些描述符，并将其传递给您的经理manager.find(Assets.SKIN)。首先，当您输入Assets.时，这会创建一个很好的所有资产列表，其次，当您分配资产时，您不需要投放或添加资产的.class，因为已经在AssetDescriptor最后你不需要字符串来查找管理器中容易出错的路径。
