Question

我编写了一个基本的Box2d-“游戏”：没有纹理等等，只有一个玩家（身体），从一个静态的地面体跳到另一个。

问题在于，地面分别是玩家身体，其后是相机，每隔几秒就会断断续续。（https://www.dropbox.com/s/llsg2q65lz828t6/stuttering.avi）（请下载此视频，否则您的Flash播放器会显示更多口吃）

如果你看看地面元素，你可以看到这非常好。

捆绑纹理也会断断续续。

奇怪的是：全屏模式没有任何卡住（config.fullscreen = true）;仅适用于Android-Phones和窗口模式。

虽然这只是一个小游戏，但我尝试使用Interpolation并分析了GC动作：没有结果：\

提前致谢！

我代码中的一些和平（我关闭了插值）：

    private float step = 1.0f / 60.0f;


public void show()
{

    //...

    bodyDef.type = BodyType.StaticBody;
    bodyDef.position.set(0, 0);


    //...
    ChainShape groundShape = new ChainShape();
    float width = 20;
    float height = 0.25f;

    fixtureDef.restitution = 0.0f;
    fixtureDef.friction = 0.5f;     
    fixtureDef.shape = groundShape;
    fixtureDef.friction = .5f;
    fixtureDef.restitution = 0;

    groundShape.createChain(new Vector2[] { new Vector2(0, 0), new Vector2(width, 0), new Vector2(width, -height), new Vector2(0, -height), new Vector2(0, 0) });

    fixtureDef.shape = groundShape;
    world.createBody(bodyDef).createFixture(fixtureDef);
    groundShape.dispose();

    groundShape = new ChainShape();
    bodyDef.position.set(25, 0);
    groundShape.createChain(new Vector2[] { new Vector2(0, 0), new Vector2(width, 0), new Vector2(width, -height), new Vector2(0, -height), new Vector2(0, 0) });

    fixtureDef.shape = groundShape;
    world.createBody(bodyDef).createFixture(fixtureDef);
    groundShape.dispose();

    //...
}

public void render(float delta)
{

    world.step(step, 8, 3);

    input.update();

    playCam.position.set(player.getBody().getPosition().x + 6.5f, 3.5f, 0);

    playCam.update();

    player.move();

    debugRenderer.render(world, playCam.combined);

}

播放器级：

    move()
    {
        playerbody.setLinearVelocity(20f, 0);
    }

（Java，LibGDX，Box2D）口吃
