How to moving one entity from a CZML postion to anther 3D tile position?

I’m new using Cesium. I have a 3D tiles on ground which have a known position. And I also have a drone flying on the sky which position defined by CZML data. I want to do some animation between the 3D tiles and drone, like drone fire bullet to attack the the 3D tiles.How can i do this?
I have a idea. that i use a bullet 3D model entity moving from drone to the 3D titles. Is this method feasible?
Thank you so much

Hi SweetHope,

That sounds like a good approach. Would love to see some screenshots/videos from your project!
