Help making a system to mount any entity | SpigotMC | Page 1

public class Plugin extends JavaPlugin implements Listener {
  public void onEnable() {
    getServer().getPluginManager().registerEvents(this, this);
  }

 @EventHandler
 public void onEntityInteract(PlayerInteractEntityEvent e) {
    Player player = e.getPlayer();
    Entity entity = e.getRightClicked();

    entity.addPassenger(player);
 }
}

I'm starting to learn Java today and I wanted to make a feature that lets a player mount any mob that can be interacted with. Nothing happens when I right click a mob.
