如何在Tiled中动态更改图块？ （AndEngine）

Question

当玩家在几秒钟后走过那个特定的瓷砖时，我想在我的瓷砖地图上掉下一块瓷砖。我该怎么做？

编辑： 我正在开发一款2D平台游戏...我希望当玩家在平台上跳跃时，该平台会在指定时间后跌落。

我为每个磁贴添加自定义属性。 TMX文件：

GameScene：

try {
        mTmxLoader = new TMXLoader(activity.getAssets(),
                engine.getTextureManager(), TextureOptions.NEAREST, vbom);
        mTmxLoader = new TMXLoader(activity.getAssets(), engine.getTextureManager(), TextureOptions.BILINEAR_PREMULTIPLYALPHA, vbom, new ITMXTilePropertiesListener() {
            @Override
            public void onTMXTileWithPropertiesCreated(final TMXTiledMap pTMXTiledMap, final TMXLayer pTMXLayer, final TMXTile pTMXTile, final TMXProperties<TMXTileProperty> pTMXTileProperties) {

                if(pTMXTileProperties.containsTMXProperty("spring", "true")) {
                final Rectangle rect=new Rectangle(??);//How do I get the coordinates of a platform
                        final FixtureDef boxFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 1f);
                      Body body=PhysicsFactory.createBoxBody(physicsWorld, rect, BodyType.StaticBody, boxFixtureDef);
                        rect.setVisible(true);
                        attachChild(rect);
                        body.setUserData("spring");
                }
                else if(pTMXTileProperties.containsTMXProperty("winter", "true")){

                }
            }
        }); 

contactListener：

if (x1.getBody().getUserData().equals("spring")
                        && x2.getBody().getUserData().equals("player")) {
                    engine.registerUpdateHandler(new TimerHandler(0.4f,
                            new ITimerCallback() {
                                public void onTimePassed(
                                        final TimerHandler pTimerHandler) {
                                    pTimerHandler.reset();
                                    engine.unregisterUpdateHandler(pTimerHandler);
                                    x1.getBody().setType(
                                            BodyType.DynamicBody);
                                }
                            }));
                }

使用Box2D并创建动态实体。当你想要删除那个身体时（几秒钟后）就消灭它的身体
