Question

我想在我的游戏主屏幕上显示文本按钮以进一步导航。但我无法这样做。我提到了libgdx文档但似乎没有任何工作。我有一个图像作为游戏背景并想要显示按钮在它上面。

这就是我想要的： enter image description here 下面是我的代码。亲切的帮助。谢谢。

public void create(){

            stage = new Stage();
            Gdx.input.setInputProcessor(stage);

            Skin skin = new Skin();
            skin.add("logo", new Texture("ic_launcher.png"));

            Pixmap pixmap = new Pixmap(1, 1, Format.RGBA8888);
            pixmap.setColor(Color.WHITE);
            pixmap.fill();
            skin.add("white", new Texture(pixmap));

            // Store the default libgdx font under the name "default".
            skin.add("default", new BitmapFont());

            // Configure a TextButtonStyle and name it "default". Skin resources are stored by type, so this doesn't overwrite the font.
            TextButtonStyle textButtonStyle = new TextButtonStyle();
            textButtonStyle.up = skin.newDrawable("white", Color.DARK_GRAY);
            textButtonStyle.down = skin.newDrawable("white", Color.DARK_GRAY);
            textButtonStyle.checked = skin.newDrawable("white", Color.BLUE);
            textButtonStyle.over = skin.newDrawable("white", Color.LIGHT_GRAY);
            textButtonStyle.font = skin.getFont("default");
            skin.add("default", textButtonStyle);

            // Create a table that fills the screen. Everything else will go inside this table.
            Table table = new Table();
            table.setFillParent(true);
            stage.addActor(table);

            // Create a button with the "default" TextButtonStyle. A 3rd parameter can be used to specify a name other than "default".
            final TextButton button = new TextButton("Click me!", skin);
            table.add(button);

            table.add(new Image(skin.newDrawable("white", Color.RED))).size(64);

} 

  public void render(float delta) {
        /*Gdx.gl.glClearColor(0,0,1.0f,1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);*/

        camera.update();
        game.batch.setProjectionMatrix(camera.combined);

        game.batch.begin();
        game.batch.draw(splsh, 0, 0,800,500);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
        Table.drawDebug(stage);
        game.batch.end();

        if (Gdx.input.isTouched()) {
            game.setScreen(new GameScreen(game));
            dispose();
        }
    }

截至目前，我只想要按钮，文字按钮或图像按钮。

render()中的代码看起来很奇怪。

首先对您自己的game.batch和舞台方法进行单独调用。那么您的render()方法看起来应如此：

public void render(float delta) {
    Gdx.gl.glClearColor(0,0,1.0f,1); // You should call this method only once outside of draw()
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    camera.update();
    game.batch.setProjectionMatrix(camera.combined);
    game.batch.begin();
    game.batch.draw(splsh, 0, 0,800,500);
    /* 
     * Render here everything that uses your camera and batch,
     * and is not a part of your stage.
     */
    game.batch.end();

    // And here is stage acts...
    stage.act(Gdx.graphics.getDeltaTime());
    stage.draw();
    Table.drawDebug(stage);

    if (Gdx.input.isTouched()) {
        game.setScreen(new GameScreen(game));
        dispose();
    }
}

现在您应该看到所有舞台演员。

顺便说一下，默认情况下管理它自己的相机和批次，所以你不必做这些事情。

希望这会有所帮助，祝你好运。
