When I’m using ‘Cesium’, I add a couple of ‘primitiveCollection’ to ‘viewer.scene.primitives’, but it doesn’t trigger the ‘viewer.scene.primitives.primitiveAdded.addEventListener’ event, only adding ‘primitive’ to it fires’ primitiveAdded’, is that the design?
Hi @zhangheng0317, welcome to the community!
Can you give us a little more information? What are you wanting to do with these events? A Sandcastle example would help us confirm our understanding of the problem. (Once you have your code working, click on the “Share” button to get a shareable link).
