Recontruct animation | Animation Nodes

I’m working on a blender animation project swords on the chair a scatter around and all of a sudden every sword starts shaking (like some magnetic power starts influencing) and then one by one all pieces coming together and forms chair.

But animation is weird!! All pieces come together at once which is not required. I want pieces to join together one by one.

I couldn’t find any Animation node Tutorial on that.

see video

Can anyone help or send me a tutorial?

Regards
