次のコードを使用して、ユーザーを自分の領域にテレポートしようとしています:
@EventHandler
public static void onPortalTravel(PlayerPortalEvent event) throws Exception {
if(event.getCause() == PlayerPortalEvent.TeleportCause.END_PORTAL) {
int x = event.getPlayer().getLocation().getBlockX();
int y = event.getPlayer().getLocation().getBlockY();
int z = event.getPlayer().getLocation().getBlockZ();
String[] data = getPageData("http://example.com/game.php?type=getRealm&location="+x+":"+y+":"+z ).split(":"); // THIS RETURNS <username>:<oldblockid>
String realm = data[0];
int oldID = Integer.parseInt(data[1].trim());
Bukkit.getServer().getWorld("world").getBlockAt(x, y, z).setTypeId(oldID);
*err* event.getPlayer().teleport(new Location(Bukkit.getWorld("realms/" + realm), 1, 65, 16.5));
}
}
エラーは次のとおりです。
