How To Use EntityDamagedByEntityEvent

hi. Im trying to use the EntityDamagedByEntityEvent so whenever you hit someone, you have a chance of getting the damage you did as extra life. So whenever i hit someone (and i did like 4 damage) i receive the damage i did (so i get 4 more hearts.) Im a little stuck because i never really use that event.. Heres the code i have so far

Code:

package plugins.mkezar;

import org.bukkit.Bukkit;
import org.bukkit.OfflinePlayer;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class Extract extends JavaPlugin implements Listener {
  
    public void onEnable() {
         Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
  
    @EventHandler
     public void onPlayerHit(EntityDamageByEntityEvent event) {
        double AmountDamaged = event.getDamage();
      
        if(event.getDamager() instanceof Player) {
          
          
          
        }
      
  

    }
}

So i basically have a double of the damage i did, now im having trouble with everything else Please Help

 

e.getDamager().setMaxHealth(double d);

And as the arguments use the max health + damage.

 

so like this?

Code:

package plugins.mkezar;

import org.bukkit.Bukkit;
import org.bukkit.OfflinePlayer;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class Extract extends JavaPlugin implements Listener {
 
    public void onEnable() {
         Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
 
    @EventHandler
     public void onPlayerHit(EntityDamageByEntityEvent event) {
        double AmountDamaged = event.getDamage();
     
        if(event.getDamager() instanceof Player) {
            e.getDamager().setMaxHealth(AmountDamaged);
         
         
        }
     
 

    }
}

if thats what im supposed to do, why is it giving me an error at the e (e.getDamager, ECT )

 

Do you want the health received to extend the 20 heart limit? For example, if I do 4 damage to someone and I have full 20 hearts, should I not have 24 hearts?

 

thats exactly what i want.

You first need to get the damage given to the player. Then get the health of the damager. If the damage given plus the damages health is greater than 20, subtract damage given from damagers health, then set the players max health to 20D + whatever you got (remember when they lose health to change the max health accordingly). If its not higher than their health, simply add the damage given to the damagers health.

 

Just make a random, if the random number is greater than a certain number, then do event.getFinalDamage() and add that to the players health.
