2 Questions - Teleporting and checking against List

Just a quick question.

What would be the best way to teleport a player backwards a certain amount of blocks as defined in a config?
Eg, Player is walking east, so they are teleported 20 blocks west.

Would player.teleport() or Vector be better?

Thanks

 

Get their targeted block (air if need be), get the vector between them and the target, change the magnitude of the vector to 20, and either teleport them to (their original location + that vector), or just do player.setVelocity(vector).

 

Thanks, will check that out when i get to it.

I have another issue though...

When i try to check if a player is near it works fine, but if the player is in the config as "blacklisted", nothing happens.
There are no errors in the console either.

            } else {

                Vector v = new Vector();
                Vector x = v.setX(-10);
                event.setCancelled(true);
                player.setVelocity(x);
                player.sendMessage(ChatColor.RED + "You are not allowed near the player " + p);
                player.sendMessage("You have been teleported back " + pb + " blocks");
 
            }
        } else {
            if (debug == true) {
                log.info("No players nearby");
            }
            return;
        }
    }
}
 
 

It shows in the console as "Players near/not near", but not Players.get(0) when within range.

What I am trying to do is;
OnEnable, add all players in the config to a list, then on the PlayerMoveEvent, check for players around them, if a player near them is in the config, throw the 1st player back x blocks.

Hopefully that makes sense.

Thanks in advanced.
