LibGDX 中的纹理图集答案

【问题标题】：Texture atlas in LibGDXLibGDX 中的纹理图集

【问题描述】：

我正在尝试加载 png 文件，但我不知道为什么它不起作用，因为我已经检查了文件路径并使用 TexturePacker 来制作纹理图集。同一路径中的其他图像工作得很好。任何帮助将不胜感激。

SpriteBatch batch;
Texture img, img2, img4;
private Player player, player2;
private Texture start, continued;
TextureRegion my, my2, my3;
TextureRegionDrawable myt, myt2, myt3;
Button button, button2;
Stage stage, stage2;
String fonte, starte, opcoes;
BitmapFont yesa, funciona;
Image ima;
Texture img3;
Sprite spider;
TextureAtlas textatlas;
FileHandle f;


 public void create(){

 Stage stage = new Stage();
    OrthographicCamera camera = new OrthographicCamera();
    camera.setToOrtho(false, 800, 480);
    batch = new SpriteBatch();
    textatlas = new TextureAtlas("TA/Agorafunfa.png");
    TextureAtlas.AtlasRegion a = textatlas.findRegion("spider");
    spider = new Sprite(a);
    //player2 = new Player("spider.png", Info.WIDTH / 2, Info.HEIGHT / 2);
    player = new Player("playerr.png", Info.WIDTH / 2, Info.HEIGHT / 2);
    img = new Texture("Captura.PNG");
    myt = new TextureRegionDrawable(my);
    yesa = new BitmapFont(Gdx.files.internal("yesa.fnt"));
    fonte = "Escape Planet";
    img2 = new Texture("comeca.png");
    img4 = new Texture("comeca.png");
    img3 = new Texture("saturno.png");
    ima = new Image(img3);
    myt2 = new TextureRegionDrawable(my2);
    funciona = new BitmapFont(Gdx.files.internal("yesa.fnt"));
    starte = "Começar";
    myt3 = new TextureRegionDrawable(my3);
    opcoes = "Opções";
    TextureRegion tx = new TextureRegion(img2);
    Drawable dr = new TextureRegionDrawable(tx);
 }

出现以下错误：

【解决方案1】：

创建纹理图集后，您应该得到 2 个文件：.png 图像和图集文件，名称和扩展名相同，如 .atlas 或 .pack。

所以你应该使用这个文件。

大概：

textatlas = new TextureAtlas("TA/Agorafunfa.atlas"); // Or Agorafunfa.pack or simillar
