Snowmen tracking players

Hi! I'm Monawar and I have a question regarding a minigame that I am programming. So I'm working on a mini-game where it requires me to make it so snowmen can track players in a continuous path, also it is a one block path. There's a minimum of three players in each round and a maximum of twenty-five players. Next, instead of the snowmen hurting players like hostile mobs would they will knock the players back. How would I program this? Please be specific when answering this.

Thank you !

@MonawarMC When you say

Are you asking to be spoonfed? Because we don't do that.

 

if (plugin.usesCustomMob)
plugin.nms = true;

I believe you would be able to do this with NMS. That's as far as I'll go, as I am not experienced with it myself.
