Help me with my rhythm game

Hi, I’m developing for my project;making some rhythm games. I want to know how the rhythms can fall down. I’ve used “Splice” blueprints, but I had some arguments with the “Timeline” blueprint, so I’m looking for some new blueprints that can work well for my game. Can I know how to get some blueprints?

You can actually understand that how to move objects(or meshes) veritical(means moving up to down). Thank you for helping me TT This is my last opportunity to make my project thanks!

oh, I’m using with Unreal Engine 4 with blueprints. thanks!
