Any method that gets hearts

Hello bukkit, I was relived when getHealth(); worked I was really happy but I realized it was not what I needed because this is what would come up player was killed by play 4.2234567667 hearts which is annoying if u ask me so is there a method to get the HEARTS that the player is on instead of the health.

Thank you.

 

I believe hearts are just health / 2.

(Someone correct me if I'm wrong)

Use Math.floor to round down to the nearest whole number of hearts. Rounding to the nearest half of a heart might be trickier, I'm sure there's some clever math to do that but offhand I can't think of how

What's wrong with NathanWolf 's answer?

 

Assist it doesn't seem to work at all it's the same thing, heres my code, correct me if im wrong.

Code:

package me.BuissnessMonkey.RadeArmor;
 
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
 
public class DeathMessage implements Listener {
   
    @EventHandler
    public void onDeath(PlayerDeathEvent e){
        double hearts = e.getEntity().getKiller().getHealth();
        Math.floor(hearts);
        Math.round(hearts/2);
        String killer = e.getEntity().getKiller().getName();
        String killed = e.getEntity().getName();
        Player SendKiller = (Player) e.getEntity().getKiller();
        Player SendKilled = (Player) e.getEntity();
        SendKiller.sendMessage(ChatColor.WHITE + killed + " " + ChatColor.RED + "was destroyed by" + ChatColor.WHITE + " " + killer + " " + hearts + ChatColor.RED + "♥");
        SendKilled.sendMessage(ChatColor.WHITE + killed + " " + ChatColor.RED + "was destroyed by" + ChatColor.WHITE + " " + killer + " " + hearts + ChatColor.RED + "♥");
 
       
    }
 
}

And im also generally not good in math so I didn't get how to go on about this.

 

Why are you doing Floor and Round?
If you're trying to get his hearts you should just do something like

Code:java

double hearts = e.getEntity().getKiller().getHealth() / 2;

 

McMhz do you know how to fix the decimal numbers?

 

I had suggested Floor as a way to get the nearest whole number of hearts (the OP's main issue is how to display the number without a lot of decimal places).

If you want to print this, I'm assuming you want a string, ultimately? If that's the case, this should work, though I still feel like this should be doable with pure math and not logic

Code:java

// Start with the full-precision health value
double health = e.getEntity().getKiller().getHealth();
 
// Use Math.floor to find the nearest whole number of hearts
// e.g. 2.3 -> 2, 5.8 -> 5
int wholeHearts = (int)Math.floor(health);
 
// Now find the remainder portion
// e.g. 2.3 -> 0.3, 5.8 -> 0.8
double remainder = health - (double)wholeHearts;
 
// Start building a string representation of our health.
String displayHealth = wholeHearts;
 
// Now figure out if we have half a heart or not.
if (remainder > 0.5) displayHealth += ".5";
 
// displayHealth now has a string which will be the player's heart level.
// This should either be a whole number (1, 2, 4, 10) or a number with a 0.5 at the end.
 

Hope that helps!

 

MonkeyPlays, it´s not a math problem.

You get the double hearts, then you floor it and do nothing with result, then you round it and again do nothing with result.
you should do:

Code:java

 double hearts = e.getEntity().getKiller().getHealth();
hearts = Math.floor(hearts); // you must place the result back in your variable

Then the Math.round() is redundant

 

Code:java

Integer intHearts = Integer.parseInt(hearts);

I guess that'd work, Might not I didn't test at all

 

McMhz parseint only works with strings

 

meh I dont know then

 

Maybe just throw a String into it?

Code:java

Integer intHearts = Integer.parseInt(String.valueOf(hearts));

or something like

Code:java

int intHearts = Double.valueOf(hearts).intValue();
