如何使用Cesium缩放实体/数据源？

Question

I tried:

czmlDataSource.load(czmlurl).then(function(){
                                viewer.dataSources.add(czmlDataSource).then(function(){
                                    viewer.flyTo(viewer.dataSources,offset);
                                });
                          });

This:

czmlDataSource.load(czmlurl).then(function(){
                                viewer.dataSources.add(czmlDataSource).then(function(){
                                    viewer.zoomTo(viewer.dataSources,offset);
                                });
                          });

And this:

czmlDataSource.load(czmlurl).then(function(){
                                viewer.dataSources.add(czmlDataSource);
                                viewer.flyTo(viewer.dataSources,offset);
                          });

And its .zoomTo equivalent without success. What to do now?

Edit: The answer that works is: viewer.flyTo(czmlDataSource) I thought I had to use the viewer's data source as in viewer.DataSources, which was my mistake, that did not work.

Stack overflow has become so stale people waste their time correcting grammar and spelling on 3 year old posts.

Answer 1

Give this a try:

viewer.dataSources.add(czmlDataSource);
czmlDataSource.load(czmlurl).then(function() {
    viewer.flyTo(czmlDataSource, options);
});

See also: viewer.flyTo for the available options .

Also remember to check the web console for any errors, and include them with your question if they are relevant.
