Getting the Distance Between Two Players

I am creating a headshot kit for my server, and am in a bit of a rut... The kit works and all, but as of right now it is too overpowered. I wish to make it so that the headshot only works if the player is at least 50 blocks away from the target. Also I would like it for the player to see how many blocks away they shot the player from. Anyone got any ideas or tips? Here is the code so far.

Code:java

  @EventHandler
              public void onHeadshot(EntityDamageByEntityEvent e) {
                  if(e.getCause() != DamageCause.PROJECTILE)
                      return;
 
                  Projectile proj = (Projectile) e.getDamager();
                  if(!(proj.getShooter() instanceof Player))
                      return;
                  Entity shot = e.getEntity();
 
                  double y = proj.getLocation().getY();
                  double shotY = shot.getLocation().getY();
                  boolean headshot = y - shotY > 1.35d;
 
                  if(headshot) {
                      e.setDamage(e.getDamage() * 20);
                      StringBuilder message = new StringBuilder(headshot ? "§7You got a headshot on§2" : "");
                      if(shot instanceof Player) {
                          message.append(" " + ((Player) shot).getName()); 
                      } else {
                          message.append(" " + shot.getType().getName());
                      }
                          ((Player) proj.getShooter()).sendMessage(message.toString());
                  }
                  }

 

float distance = player1.getLocation().getDistance(player2.getLocation());

Thanks man. But There is a few errors this is what I have so far. There is an error under line 16 at .getDistance. Also, how would I make a check to see if they are 50 blocks away?

Code:java

@EventHandler
public void onHeadshot(EntityDamageByEntityEvent e) {
if(e.getCause() != DamageCause.PROJECTILE)
return;
if (!plugin.playerWithin(l1, l2, e.getEntity().getLocation())) {
Projectile proj = (Projectile) e.getDamager();
Player p = (Player)proj.getShooter();
if(!(proj.getShooter() instanceof Player))
return;
Player shot =(Player) e.getEntity();
 
double y = proj.getLocation().getY();
double shotY = shot.getLocation().getY();
boolean headshot = y - shotY > 1.35d;
 
float distance = p.getLocation().getDistance(shot.getLocation());
if(headshot) {
e.setDamage(e.getDamage() * 20);
StringBuilder message = new StringBuilder(headshot ? "§2" + p.getName() + " §7has gotten a headshot on§2" : "");
if(shot instanceof Player) {
message.append(" " + ((Player) shot).getName());
} else {
message.append(" " + shot.getType().getName());
}
Bukkit.broadcastMessage(message.toString());
 
}
}
}

 

There's no getDistance() method for the Location class, there's distance():

Code:java

double distance = p.getLocation().distance(shot.getLocation());

This code should work:

Code:java

@EventHandler
public void onHeadshot(EntityDamageByEntityEvent e) {
    if(e.getCause() != DamageCause.PROJECTILE)
        return;
 
    Projectile proj = (Projectile) e.getDamager();
 
    if (!(proj.getShooter() instanceof Player) || !(e.getEntity() instanceof LivingEntity))
        return;
 
    Player shooter = (Player)proj.getShooter();
    LivingEntity shot = (LivingEntity)e.getEntity();
 
    double y = proj.getLocation().getY();
    double shotY = shot.getLocation().getY();
    boolean headshot = y - shotY > 1.35d;
 
    double distance = shooter.getLocation().distance(shot.getLocation());
 
    if (headshot && distance > 25) {
        e.setDamage(e.getDamage() * 20);
        StringBuilder message = new StringBuilder("§2" + shooter.getName() + " §7has gotten a headshot on§2");
        if(shot instanceof Player)
            message.append(" " + ((Player) shot).getName());
        else
            message.append(" " + shot.getType().getName());
 
        Bukkit.broadcastMessage(message.toString());
    }
}
