Question

我遇到TiledMapRenderer的问题。我在地图中使用Tiled Map Editor创建了一个带有4个图块对象和1个图块64x64的tmx贴图。但我无法弄清楚我错过了什么。屏幕上没有任何内容。地图和图块集位于assets文件夹中。我已经谷歌了很多，复制了教程中的粘贴代码和GDX TiledMap测试，但除了fps计数器和摄像头位置外，我的Alcatel One Touch Pixi 4007d GLES 2.0手机上看不到任何内容。我错过了什么？可能答案对其他新手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，地图中也有一个图层。

以下是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。 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());

libGDX TiledMapRenderer没有绘图
