libGDX TiledMapRenderer 不绘图

Question

TiledMapRenderer 有问题。我用Tiled Map Editor 制作了一个 tmx 地图，其中包含 4 个平铺对象和 1 个 64x64 平铺。但我无法弄清楚我错过了什么。屏幕上什么都没有。地图和瓦片集位于资产文件夹中。我有很多谷歌，从教程和GDX TiledMap 测试中复制粘贴的代码，但在我的Alcatel One Touch Pixi 4007d GLES 2.0 准备好的手机上看不到任何东西，除了fps 计数器和相机位置。我错过了什么？答案可能对其他新手libGDX 程序员有帮助。 我已经在调试器中检查了地图，并且所有变量都已初始化，地图中还有一个图层。

这是Game类的代码

public class GameMain extends Game implements InputProcessor
{ 
private TiledMap map;
private TiledMapRenderer renderer;
private OrthographicCamera camera;
private BitmapFont font;
private SpriteBatch batch;

Vector2 mPrevTouch;

@Override
public void create () {
    float w = Gdx.graphics.getWidth();
    float h = Gdx.graphics.getHeight();

    camera = new OrthographicCamera();
    camera.setToOrtho(false, (w / h) * 10, 10);
    camera.update();

    Gdx.input.setInputProcessor(this);

    font = new BitmapFont();
    batch = new SpriteBatch();

    map = new TmxMapLoader().load("test.tmx");
    renderer = new OrthogonalTiledMapRenderer(map);
}

@Override
public void render () {
    Gdx.gl.glClearColor(0.55f, 0.55f, 0.55f, 1f);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    camera.update();

    renderer.setView(camera);
    renderer.render();

    batch.begin();
    font.draw(batch, "FPS: " + Gdx.graphics.getFramesPerSecond(), 10, 20);
    font.draw(batch, "Pos: " + camera.position.x + " " + camera.position.y, 20, 20);
    batch.end();        
}

@Override
public void dispose () {
    map.dispose();
}    

@Override
public boolean keyDown(int arg0) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean keyTyped(char arg0) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean keyUp(int arg0) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean mouseMoved(int arg0, int arg1) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean scrolled(int arg0) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean touchDown(int arg0, int arg1, int arg2, int arg3) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean touchDragged(int screenX, int screenY, int arg2) {

    if (mPrevTouch == null)
        mPrevTouch = new Vector2(0, 0);
    else
        camera.translate(new Vector2(screenX - mPrevTouch.x, screenY - mPrevTouch.y));

    mPrevTouch.x = screenX;
    mPrevTouch.y = screenY;

    return true;
}

@Override
public boolean touchUp(int arg0, int arg1, int arg2, int arg3) {
    // TODO Auto-generated method stub
    return false;
}
}

您的代码看起来不错，所以我认为您的相机尺寸或相机位置有问题。您的 TMX 地图的大小是多少？ + 尝试以这种方式创建相机：

    tiledMapCamera.setToOrtho(false, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
