Create an egg grenade

I am trying to create a grenade out of an egg.
It must bounce when it hits the ground and must explode 3 seconds after leaving the players inventory

This is my code so far can anyone help me finish it?

public class GrenadeListener implements Listener {

private static final PlayerEggThrowEvent PlayerEggThrowEvent = null;
PlayerEggThrowEvent event = PlayerEggThrowEvent;
TNTPrimed TNT = null;
ExplosionPrimeEvent nade = new ExplosionPrimeEvent(TNT, 4, true);

@EventHandler()
public void eggThrow(PlayerEggThrowEvent event){
Player p = event.getPlayer();
event.setHatching(false);
event.getEgg().setVelocity(p.getLocation().getDirection().normalize().add(new Vector(0,2.5,10)));

}


@EventHandler()
public void eggHit(ProjectileHitEvent event2){
event2.getEntity().getWorld().createExplosion(event.getEgg().getLocation(), 4);


}

}

 

Normally people would post code using the code option, but this is how i do a grenade, you should be able to just edit this

Code:

@EventHandler(priority = EventPriority.NORMAL)
    public void onPlayerThrowEvent(PlayerInteractEvent event){
        Player player = event.getPlayer();
        if(InfectedApi.isPlayer(player))
            if(plugin.getConfig().getBoolean("Grenades.Use"))
                if (player.getItemInHand().getType() == Material.SLIME_BALL) {
                    final Item grenade = event.getPlayer().getWorld().dropItem(player.getEyeLocation(), new ItemStack(Material.SLIME_BALL));
                    grenade.setVelocity(event.getPlayer().getEyeLocation().getDirection());
                    item.add(grenade.getUniqueId().toString());
                    player.getInventory().removeItem(grenade.getItemStack());
                    Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                        @Override
                        public void run() {
                            grenade.getWorld().playEffect(grenade.getLocation(), Effect.SMOKE, 5);
                            for(Player ppl : Bukkit.getServer().getOnlinePlayers())
                                if(InfectedApi.isPlayer(ppl)&&ppl.getLocation().distance(grenade.getLocation())<5){
                                    ppl.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 140, 2));
                                    ppl.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 40, 1));
                                }
                            grenade.remove();
                            grenade.playEffect(EntityEffect.WOLF_SMOKE);
                            item.remove(grenade.getUniqueId().toString());
                        }
                    }, 80L);
                    event.setCancelled(true);
                    }
           }
    }
}

 

thanks i will try this. Sorry i am new

Can i ask what is the variable "plugin"?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

In the class we're talking about (GranadeListener), you'll have something like this:

Code:Java

 
private {NAME_OF_MAIN_CLASS} plugin;
public {NAME_OF_CLASS}({NAME_OF_MAIN_CLASS} instance){
     plugin = instance;
}
 

When making an instance of this class (which you would normally do in the main plugin class), instead of doing:

Code:Java

 
new GranadeListener();
 

...we'll add 'this' in the brackets, so it looks like this:

Code:Java

 
new GranadeListener(this);
 

'This' revers to the instance of the main plugin class. That's why we added the name of the main class in the 'plugin' variable.

 

I am completely lost now. Can you check to see if this is right?

Code:

package net.minez;
 
import org.bukkit.plugin.java.JavaPlugin;
 
public class Grenade extends JavaPlugin{
    public void onEnable(){
        getServer().getPluginManager().registerEvents(new GrenadeListener(), this);
    }
 
}

Code:

import org.bukkit.entity.TNTPrimed;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.ExplosionPrimeEvent;
import org.bukkit.event.entity.ProjectileHitEvent;
import org.bukkit.event.player.PlayerEggThrowEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.util.Vector;
 
public class GrenadeListener implements Listener {
    private Grenade plugin;
    public GrenadeListener(Grenade instance){
        plugin = instance;
    }
   
    private static final PlayerEggThrowEvent PlayerEggThrowEvent = null;
    PlayerEggThrowEvent event = PlayerEggThrowEvent;
    TNTPrimed TNT = null;
 
    @EventHandler()
    public void eggThrow(PlayerEggThrowEvent event){
        Player p = event.getPlayer();
        event.setHatching(false);
        final Item grenade = event.getPlayer().getWorld().dropItem(event.getEgg().getLocation(), new ItemStack(Material.EGG));
        grenade.setVelocity(event.getPlayer().getEyeLocation().getDirection());
        p.getInventory().removeItem(grenade.getItemStack());
        grenade.getWorld().createExplosion(grenade.getLocation(), 4);
        plugin.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
 
            public void run() {
                grenade.getServer().broadcastMessage("This message is broadcast after 3 seconds");
            }
        }, 60L);
 
    }
   
   
}

package me.farkinklown;

}
 
 
@EventHandler
    public void eggThrow(PlayerEggThrowEvent event){
        event.setHatching(false); // no baby chickens.
        final Item grenade = event.getPlayer().getWorld().dropItem(event.getEgg().getLocation(), new ItemStack(Material.EGG)); //spawn egg at landing location to allow for bounce.
        grenade.setVelocity(event.getPlayer().getEyeLocation().getDirection());
        grenade.getLocation().add(event.getEgg().getVelocity());  //move egg from land location to simulate bounce.
        grenade.getWorld().playSound(grenade.getLocation(),Sound.CREEPER_HISS, 1, 1); // plays creeper his sound when hits the ground, bit of a warning for players.
        grenade.setPickupDelay(41); //Delay so grenade cant be picked up. note: make longer then "runtasklater" delay.
        new BukkitRunnable() {
            @Override
            public void run() {
          grenade.getWorld().createExplosion(grenade.getLocation(), 4, false); // make egg explode (location, size, fire)
                grenade.remove(); // get rid of egg so it cant be picked up
            }
        }.runTaskLater(this.plugin, 40);
 
    }
 
 
}
 
 
 
 

im only a very noob at coding, but this is what i have come up with and it seems to be working.

also i know this is an old post, but i found it useful for most the code, i just tweeked it my way
