RSSEnt Follow Players

[MYGO.pl]

Hello I have this code that makes the grenades follow the enemy, I wanted to know if it is possible (and how) to make the player follow other players?

Or if it is possible to create an entity that follows players, but the player in turn chases them through the entity?

PHP Code:
