Getting the distance between two players

So basically I'm creating a very very very very bare minimum anti-reach plugin and want to get the distance between two players. The best way I thought of was checking the distance between two players using the distance formula, but is there any better way to do this? Are there any downsides to using this method?

Code:

Code:java

 
package reach.endran.eltik;
 
import java.text.SimpleDateFormat;
import java.util.Date;
 
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
 
public class PlayerListeners implements Listener {
 
    // Get's the data + time for logging purposes.
    Date now = new Date();
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
 
    private Core core;
 
    public PlayerListeners(Core core) {
        this.core = core;
    }
 
    @EventHandler
    public void onHit(EntityDamageByEntityEvent event) {
        Player player = (Player) event.getDamager();
 
        Player entity = (Player) event.getEntity();
 
        // If the damager damages the damaged...   
        if (((event.getDamager() instanceof Player)) && ((event.getEntity() instanceof Player))) {
            double distance = Math.sqrt(Math.pow(((player.getLocation().getX() - entity.getLocation().getX())), 2) + Math.pow(((player.getLocation().getY() - entity.getLocation().getY())), 2) + Math.pow(((player.getLocation().getZ() - entity.getLocation().getZ())), 2));
            player.sendMessage("You hit " + entity.getName() + " with a reach of " + distance);
            core.otherLog("[" + format.format(now) + "] " + player.getName() + " hit " + entity.getName() + " with a reach of " + distance);
        }
    }
 
}
 
 

 

No and no.

 

Oh. Okay well thank you lmao

You can always make it look a little nicer by creating a method to do it.

Also, there is Location#distance(Location), though you might want to take a look at Location#distanceSqaured(Location) too.
