label collection

CesiumJS
1

I have encountered a stuck.I want to add label entity by an iteration. But after adding label entities by iteration,they don’t show on the globe,code like this:

var labels = Cesium.LabelCollection();

window.onload = function(){

viewer.dataSources.add(Cesium.KmlDataSource.load(’…/obor/kml/recountry.kml’));

var i;

for(i=0;i<145;i++)

{

labels.add({ //if i replace the “labels” by viewer.entities,it does show on the globe! why?

position : Cesium.Cartesian3.fromDegrees(all_lng_array[i], all_lat_array[i]),

label : {

text : all_name_array[i],

font : '22px YouYuan ',

}

})};

When using the lower level LabelCollection instead of entities, you need to add the collection to the scene for rendering:

var labels = viewer.scene.primitives.add(new Cesium.LabelCollection());

Thanks a million for your help!
As you told, I have modified my code clip like this:

var labels = viewer.scene.primitives.add(new Cesium.LabelCollection());

for(var i=0;i<all_name_array.length;i++)

{

labels.entities.add({

position : Cesium.Cartesian3.fromDegrees(all_lng_array[i], all_lat_array[i]),

label : {

text : all_name_array[i],

font : '18px YouYuan ',

fillColor : Cesium.Color.YELLOW,

outlineColor : Cesium.Color.WHITE,

outlineWidth : 1,

style : Cesium.LabelStyle.FILL_AND_OUTLINE

}});

};

However, it still doesn’t help ,the labels do not show on the globe.It must be something wrong in my code,…Eh…

But thanks a lot again!
