Pluginomnak a kódja a PlayerMoveEventnél.
public void onMove(PlayerMoveEvent e) {
java.sql.PreparedStatement ps;
// LOGIN //
try {
ps = sql.getConnection().prepareStatement("SELECT isLoggedIn FROM users WHERE username=?");
ps.setString(1, e.getPlayer().getName());
ResultSet results = ps.executeQuery();
if(results.next()) {
regellenorzott = results.getBoolean("isLoggedIn");
if(regellenorzott == false) {
e.setCancelled(true);
}
}
} catch (SQLException e1) {
e1.printStackTrace();
}
Látom, a warningnál, hogy hol a hiba, de az egy integer. nemtudom mi baja vele.
