Java 停止摄像机移动

我一直试图停止移动我地图末端的相机，但它仍在继续移动

这是我的密码：

@Override
public void render(float delta) {       
//moving tiled map
camera.position.x=camera.position.x+Gdx.graphics.getDeltaTime()*200;

camera.update();
//...........................................

Gdx.gl.glClearColor(1, 0, 0, 0);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);


// renderer camera and map
renderer.setView(camera);
renderer.render();
//...................................................

  }

   @Override
   public void show() {

   batch = new SpriteBatch();


   map = new TmxMapLoader().load("maps/map1.tmx");

   renderer = new OrthogonalTiledMapRenderer(map);

   camera = new OrthographicCamera();
   }

   @Override
   public void hide() {

   }

   @Override
   public void create() {

   }

  @Override
  public void resize(int width, int height) {
  camera.viewportWidth = width;
  camera.viewportHeight = height;
  camera.position.set(width/2f, height/3f, 0); //by default camera position on (0,0,0)
  camera.update();


  }

  @Override
  public void render() {



  }

 @Override
 public void pause() {


 }

@Override
public void resume() {


}

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

}
}

我在代码中找不到任何错误

因此，我这里的问题是，如何阻止摄影机在贴图末尾移动？

平铺贴图中至少有一层，因此：

TiledMap map = ......//whatever method that you are using to load a map
//skip to the part that the map is loaded
TiledMapLayer layer = (TiledMapLayer)map.getLayers().get(0);
int layerWidth = layer.getWidth()*layer.getTileWidth();

现在，您知道了层的宽度（以像素为单位），您可以确保

camera.position.x+Gdx.graphics.getDeltaTime（）*200从不超过此长度
