MapObjects Libgdx/Tiled Object 属性？

Question

我有一个 TMX 文件，其中包含一个平铺图像层和一个对象层。我已将其全部导入到我的 libGDX 项目中，但似乎无法将每个对象的 Rectangle 坐标输入到我的代码中。请参阅下面我的 Level 类和 TMX 文件以供参考。 （我已经坚持了好几天了，这太令人沮丧了，我已经尝试了几十件事，现在我一团糟！）：

        camera.update();

        MapLayer layer = map.getLayers().get("platforms");

            }
        }
        for (int i = 0; i < platformRects.size; i++){
            platform = new Platform(platformRects.get(i));
            mainStage.addActor(platform);
        }
    }

    public void draw() {

        spriteBatch.begin();
        renderer.setView(camera);
        renderer.render();

        font.draw(spriteBatch, "plat Rects count: " + sizeTest, 0, 0);
        spriteBatch.end();
    }
}

还有 TMX 文件........

Answer 1

我想这就是你要找的……

    if(object instanceof TextureMapObject) {
        TextureMapObject mapObject = (TextureMapObject) object;
        this.bounds = new Rectangle(mapObject.getX(), mapObject.getY(),
                                    mapObject.getTextureRegion().getRegionWidth(),
                                    mapObject.getTextureRegion().getRegionHeight());
    }
    else
        this.bounds = ((RectangleMapObject) object).getRectangle();
