现在创建了entity，想把他放到entitycolletion中，已经放进去了在但是请问entitycollection如何加载呢。

使用viewer.dataSources.add加载报错

您好，方便发一下您那边的代码吗，我测试一下

Comments

var AAA = new Cesium.EntityCollection("DC");

        var entity = new Cesium.Entity({

                position: Cesium.Cartesian3.fromDegrees(116.0,39.9,400),

                point: {

                    color: Cesium.Color.RED,    //点位颜色

                    pixelSize: 10,                //像素点大小

                },

            });

            AAA.add(entity);

             viewer.dataSources.add(AAA);

您好，entity创建之后就会显示出来，使用viewer.zoomTo(entity)可以定位到当前实体的位置，参考代码

var entity = viewer.entities.add({
		polygon: {
			hierarchy: {
				positions: [new Cesium.Cartesian3(290254.5148736448, 5637924.074937166, 2971777.4768239637),
					new Cesium.Cartesian3(286432.14053509803, 5640804.651089405, 2966391.9275969476),
					new Cesium.Cartesian3(283512.2666752818, 5640502.494127799, 2969385.3689191523),
					new Cesium.Cartesian3(287036.36797237827, 5636827.146248645, 2974105.8904601005)
				]
			},
			material: Cesium.Color.BLUE.withAlpha(0.5)
		}
	});
            
            
            AAA.add(entity);
            viewer.zoomTo(AAA._entities._array[0])
