Rightclick event on a far away player

Hi ! I tried to find the answer for hours on many forums but I failed..

I would like to make a vote system in a plugin by right clicking on others players BUT they can be far away (maybe maximum 20 blocks away).

Basically, this is working :

Code:

@EventHandler
public void RightClick(PlayerInteractEntityEvent e)
{
    Player p = e.getPlayer();
    if(e.getRightClicked() instanceof Player) {
        // Add the player UUID to HashMap
    }
}

But ONLY if the player is near...

What can I do ? I thought about shooting with right click, then cancelling the damage and get the uuid of the player hit?

Thank you for your help ❤

 

@Themiller I think this might help you.

Alright Thank you ! I created Ray and AABB Classes and I did this :

Code:

public static Player getTargetPlayer(Player player, int max) {
    List<Player> possible = player.getNearbyEntities(max, max, max).stream().filter(entity -> entity instanceof Player).map(entity -> (Player) entity).filter(player::hasLineOfSight).collect(Collectors.toList());
    Ray ray = Ray.from(player);
    double d = -1;
    Player closest = null;
       for (Player player1 : possible) {
           double dis = AABB.from(player1).collidesD(ray, 0, max);
           if (dis != -1) {
               if (dis < d || d == -1) {
                   d = dis;
                   closest = player1;
               }
           }
      }
    return closest;
}


@EventHandler(priority = EventPriority.LOWEST, ignoreCancelled = true)
public void onPlayerInteract(PlayerInteractEvent e) {
      Player p = e.getPlayer();
      if ((e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) || (e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.LEFT_CLICK_BLOCK)) {
            Bukkit.broadcastMessage("You voted for : " + getTargetPlayer(p, 2));
     }
   }

But it always return a null value... What is wrong in my code ?

Thank you again for your help

 

@Themiller Unfortunately i've never tried ray-tracing myself, so i can't help any further.

Hopefully someone else can help you.

 

@KarimAKL Np thank you for your help, I managed to make it work !

But now I would like to display number of votes on a player above his head and his name. Do you have some ideas ?

 

Hello, maybe you can change player's display name, or create an invisible armor stand with custom name that's riding the player.
