LibGDX拼接纹理文件

Question

我有一个图像，它由块（32 * 32）组成，有1行和4列。我该怎么办，当我加载纹理时，我只加载一个块而不是全部4个块？

方法1）

    Texture texture=new Texture(Gdx.files.internal("ui/logo2.png"));
    Sprite sprite=new Sprite(texture);
    sprite.setRegion(0, 0, 1f/4f, 1);//this loads the first block
    sprite.setRegion(1f/4f, 0, 1f/4f+1f/4f, 1);//this loads the second block
    sprite.setRegion((1f/4f)*2, 0, 1f/4f+(1f/4f)*2, 1);//this loads the third block
    //on render
    sprite.draw(theSpriteBatch);   

方法2）

    Texture texture=new Texture(Gdx.files.internal("ui/logo2.png"));
    TextureRegion[][] tmp = TextureRegion.split(texture, 32, 32);
    Sprite sprite=new Sprite(tmp[0][0]);//first
    Sprite sprite=new Sprite(tmp[0][1]);//second
    Sprite sprite=new Sprite(tmp[0][2]);//third
    //on render
    sprite.draw(yourSpriteBatch);
