java - 运行 5 分钟后，我的 libgdx 游戏崩溃并变黑

Question

我的应用程序在前五分钟运行良好，但在一段时间后它崩溃了。`

public class fixGame implements ApplicationListener {

    Texture paper;
    SpriteBatch spritebatch;
    Vector2 position;
    Vector2 size;

    String myScore;

    BitmapFont font;
    boolean collision = false;
    @Override
    public void create() {  
        float delaySeconds = 1;
        spriteBatch = new SpriteBatch();
    trash = new Texture(Gdx.files.internal("data/trash.png"));
    paper = new Texture(Gdx.files.internal("data/paper1.jpg"));
    position = new Vector2(100, 50);
    pos = new Vector2(54, 14);
    batch = new SpriteBatch();
    BitmapFont font = new BitmapFont();

    size2 = new Vector2(trash.getWidth() ,trash.getHeight() );
    //size2.y = trash.getHeight();
    //size2.x = trash.getWidth();
    size = new Vector2(paper.getWidth() ,paper.getHeight());

    bounds= new Rectangle(pos.x, pos.y, size.x, size.y);
    bounds2= new Rectangle(position.x, position.y, size2.x, size2.y);

    }

    @Override
    public void dispose() {

    }
    public void update(){
        bounds.set(pos.x, pos.y, size.x, size.y);
        bounds2.set(position.x, position.y, size2.x, size2.y);

        position.x = position.x -2- Gdx.input.getAccelerometerX();
    }




    @Override
    public void render() {

        if(bounds.overlaps(bounds2)){
            collision=true; 
            counted=true;
        }else{
            collision=false;
        }

        if(collision==true){

        } 

        if(pos.y<640){
            counted=false;
        } else if(pos.y > 640 && collision==false && counted==false){
            counted=true;
            score= score-1;
            myScore = "Your Score: " + score;
            str = myScore;
        }


        BitmapFont font = new BitmapFont();
          update();
            Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        pos.y=pos.y-12;
        if(pos.y<0){
            pos.y = 700;
            Random randomGenerator = new Random();
              pos.x = randomGenerator.nextInt(500);
        }



        batch.begin();
        batch.draw(paper, pos.x, pos.y);
        batch.draw(trash, position.x, position.y);

        font.setColor(0.0f, 0.0f, 1.0f,1.0f);
        font.draw(batch, str, 300,250);
                batch.end();

    }

     @Override  
    public void resize(int width, int height) {
    }

    @Override
    public void pause() {
    }

    @Override
    public void resume() {
    }
}

我不确定发生了什么，任何帮助将不胜感激。我想知道的另一件事是，eclipse，我用来运行我的程序没有给出任何错误，因为我的应用程序崩溃了。提前致谢

在渲染循环中，每次循环运行时都会创建一个新的 BitmapFont 对象。尽管 libgdx 管理某些对象的内存，this链接表示 BitmapFont 在使用完毕后需要进行处理，否则您的游戏将继续为每个新对象分配内存。因为您已经在 create 方法中创建了 font，所以您不需要再次实例化它。当您使用完它后，您可以在您已经使用 font.dispose() 之类的方法设置的 dispose() 方法中处理它。
