[Solved][Thanks Njol]Notive a PlayerChangedWorldEvent and cancel it

Hi there, i want to block a player from a specific world if he is added to a file.
I dont really know which event to use, either the PlayerChangedWorldEvent which isnt cancelable as far as i know and the PlayerTeleportEvent which doesnt work for me.
Maybe you can help me

PHP:

@EventHandler
               public void playerJoin(PlayerTeleportEvent event) {
       
               if (event.getTo().getWorld().toString().equalsIgnoreCase(getConfig().getString("world"))){
               
               List<String> deaths = getConfig().getStringList("dead");
               
               if(deaths.contains(event.getPlayer().toString().toLowerCase())) {
               event.getPlayer().sendMessage("you are already dead");
               event.setCancelled(true);
               
               
               }

Thanks for your help

You have to use world.getName(), not world.toString() to get a world's name. The same applies to players as well.

 

Thanks Njol for helping me again=)
