Solved Prevent players from getting stuck

Hey, thank you for taking time to read this.
I have a little problem i cannot fix and need help with.
I have a basic border i dont want players to cross, but somehow they keep getting stuck in the border.
So i came up with a solution which was great at first. It basically threw players backwards when on the border.

Code:

        IListener.Listen move = new IListener.Listen(PlayerMoveEvent.class) {

            @Override
            public void onEvent(Event event) {
                if (event instanceof PlayerMoveEvent) {
                    PlayerMoveEvent e = (PlayerMoveEvent) event;

                    if (!arena.getCuboid().withinCuboid(e.getTo())) {
                        Player player = e.getPlayer();

                        player.setVelocity(player.getLocation().getDirection().setY(0).multiply(-0.2));
                        e.setTo(e.getFrom());

                        if (duel.isEnded()) {
                            this.cancel();
                            DuelIt.listener.unregister(this);
                        }
                    }
                }
            }
        };

Although this works the way i wanted it to i soon realised that when you enter the border from an angle you get stuck again. How can i prevent this?

 

if you're using 1.8 send blockchange of a barrier block when the player is near 2-3 blocks

 

@Ruptur
Why are you using the Event event instead of PlayerMoveEvent directly? Also, why not just add a method to teleport the player to another location if they are stuck?

 

@Zombie_Striker
How do i know if the player is stuck?

@FisheyLP
With this then the players wont get bounced

 

@Ruptur
Well, how do you? If you can tell that a player can get stuck, why cant the server?

 

@Zombie_Striker
I know the player gets stuck because i went ingame to test it out. Once glitched into the border i get rebounded back then rebounded opposite ways but the movement is minute.

 

@Ruptur, which direction are you throwing them? directly horizontal? You'll have to add a vertical vector too.

 

@Tecno_Wizard
I throw them horizontal, although it throw throw them up a bit.

 

@Ruptur, put a direct vertical acceleration in it.

 

Thanks for your all tips.
I have solved this issue but reducing the amount the players are bounced back by.

From

Code:java

 
player.setVelocity(player.getLocation().getDirection().setY(0).multiply(-2));
 

To

Code:java

 
player.setVelocity(player.getLocation().getDirection().setY(0).multiply(-0.2));
