Hello, I'm brazilian and I'm studying Java and Bukkit API for develop plugins. I started with editing a plugin called EnderPearlDisable for up date it. But the Bukkit API changed the events system and I'm lost Could anyone help me? This is the code: Code: public void onEnable() { SimplePluginManager.registerEvent(Event.Type.PLAYER_INTERACT_ENTITY, new Listener() { public void onPlayerInteract(PlayerInteractEvent event) { if (event.getItem() != null && event.getItem().getType() == Material.ENDER_PEARL) { event.getPlayer().sendMessage(ChatColor.RED+"Ender Pearl não funciona."); event.setCancelled(true); } } }, EventPriority.NORMAL, this); System.out.println("Ender Pearl TP blocking enabled."); } The Eclipse say the method of 'SimplePluginManager.registerEvent' is wrong. Other questions: How I use a event type like 'Event.Type.PLAYER_INTERACT_ENTITY' in Bukkit API 1.1 R3? Could anyone inform a tutorial about create config files Thanks for read
