Copying Movements of Player to another

I want to make a player replicate my Movements. I tried using .setVelocity but that doesn't seem to apply to simple movements. Would I have to replicate my key presses then?

Current onWalk Code, meant to replicate movement.

Code:

@EventHandler
    public void onWalk (PlayerMoveEvent e) {
       
        if (paar.containsKey(e.getPlayer())) { //check if player is "holding hands"

           
            Player halter = e.getPlayer();

            Vector movement = halter.getVelocity(); //copy their momentum
       
   
           
           
            paar.get(halter).setVelocity(movement); //set their momentum
       

        }
    }

 

Just use getFrom() and getTo() and then subtract the difference and teleport the other player with the increment. You will also need to cancel the PlayerMoveEvent if the other player that's being controlled tries to move.
