Need help making an object throw-able

Hi,
I making a Call Of Duty plugin for my server and I'm trying to make objects throw-able and then explode after a couple of seconds. Any help would be great!

 

kind of like dropping a green dye on the ground and then it cause an explotion? should be easy, i think. won't get much range on it though

 

Ok, I just wanted to make something like a snowball give you blindness if you are to close to where the snowball exploded.

Could anyone please send me the code to do this? Sorry, I'm kind of a beginner

ok, the only things that can be thrown in the game is snowball, enderpearl and egg, if i'm not mistaken. you get make it explode on impact, if that's what you want, but no one will give you code just like that, you're supposed to learn.

 

People would actually give him the code, but still he should learn

 

Okay so, this is really easy. I spent a long time figuring this out even though it was super easy lol.

My code for slimeball grenades

Code:

    @EventHandler
    public void slimeGrenade(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        World world = player.getWorld();
        if (player.hasPermission("perm.here")) {
            if (player.getItemInHand().getType() == Material.SLIME_BALL) {
                if (event.getAction() == Action.LEFT_CLICK_AIR) {
                    final Item grenade = world.dropItem(player.getEyeLocation(), new ItemStack(Material.SLIME_BALL));
                    grenade.setVelocity(player.getEyeLocation().getDirection());
                    plugin.getServer().getScheduler().scheduleAsyncDelayedTask(plugin, new Runnable() {
 
                                @Override
                                public void run() {
                                    grenade.getWorld().createExplosion(grenade.getLocation(), 0.0F);
                                    grenade.remove();
                                }
                            }, 40L);
                }
            }
        }
    }

to make any item throwable you just do
Item grenade = world.dropItem(player.getEyeLocation() new ItemStack(Material.YOURMATERIAL);
grenade.setVelocity(player.getEyeLocation().getDirection());

code for snowball grenades

Code:

    @EventHandler
    public void onHit(ProjectileHitEvent event)
    {
      if (event.getEntity() instanceof Snowball)
      {
        Entity e = event.getEntity();
        Location loc = event.getEntity().getLocation();
        World world = event.getEntity().getWorld();
        world.playEffect(loc, Effect.STEP_SOUND, 50);
        List<Entity> entities = e.getNearbyEntities(5, 5, 5);
        for (Entity entity : entities)
        {
            if (entity instanceof Player)
            {
              ((Player)entity).addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 200, 0));
              ((Player)entity).addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 200, 7));
              ((Player)entity).addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 200, 1));
                }
            }
        }
    }

I'm that guy. :>

Thanks so much! I'll study the code and put it in my Call Of Duty plugin

Also, would the code make an explosion effect? If not do you mind adding that please, thanks.

PS, You've earned a like Loogeh!

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

 

The slimeball creates an explosion with a delay, it does not damage to players or blocks though because the power is set to 0.0F (F = float)

 

Oh, one more thing, I was looking at you're code and the

Code:

if (event.getAction() == Action.LEFT_CLICK_AIR) {

can I change the LEFT_CLICK_AIR to RIGHT_CLICK_AIR?

 

Id say try it
Thats where you learn the most of

 

brord WinX-9 Loogeh gomeow
Btw it is possible to throw any kind of items not just eggs/snowballs and... enderpearls.
I did a slime ball throwing plugin just a few weeks ago, that created a fake explosion after a configurable amount of time and blinded nearby players(radius also configurable)

 

Didnt Loogeh made that a couple of posts up? 0.o

 

oh he did o.o I didnt even notice

 

Do you mind if you send me the code? If not I fully understand

 

Loogeh did it up there. Go check it out o.o his code is actually a bit different than mine but does nearly the same o.o

 

Thanks!

 

Cool guys!

 

For Loogeh's code what would I have to import?

 

WinX-9
You have to set up your own Java Project. The only thing you should do is add Craftbukkit as an external jar. Other than that, just hover over the red lines and hit import.

 

Thanks Royal_Soda!

Here is my main class code so far:

Code:

package com.grenade.semtex;
 
import java.awt.Desktop.Action;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.entity.Item;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class GrenadeSemtex extends JavaPlugin {
 
    @EventHandler
    public void slimeGrenade(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        World world = player.getWorld();
        if (player.hasPermission("perm.here")) {
            if (player.getItemInHand().getType() == Material.SLIME_BALL) {
                if (event.getAction() == Action.LEFT_CLICK_AIR) {
                    final Item grenade = world.dropItem(player.getEyeLocation(), new ItemStack(Material.SLIME_BALL));
                    grenade.setVelocity(player.getEyeLocation().getDirection());
                    plugin.getServer().getScheduler().scheduleAsyncDelayedTask(plugin, new Runnable() {
 
                                @Override
                                public void run() {
                                    grenade.getWorld().createExplosion(grenade.getLocation(), 0.0F);
                                    grenade.remove();
                                }
                            }, 40L);
                }
            }
        }
    }
}

Does anyone see any problems with this?

That won't work. You need to fix it up, here is what I did:

MainClass:

Code:

package plugin.pluginhere;
 
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
public class MainClass extends JavaPlugin {
   
    public final ListenerClass Listener = new ListenerClass();
 
    public void onEnable() {
       
        PluginManager pm = getServer().getPluginManager();
       
        pm.registerEvents(this.Listener, this);
       
        getLogger().info("PLUGIN is now enabled.");
       
    }
   
    public void onDisable() {
       
        getLogger().info("PLUGIN is now disabled.");
       
    }
   
}

ListenerClass:

Code:

package plugin.pluginhere;
 
import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.entity.Item;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.Plugin;
 
public class ListenerClass implements Listener {
   
    @EventHandler
    public void slimeGrenade(PlayerInteractEvent event) {
       
        Player player = event.getPlayer();
        World world = player.getWorld();
        Plugin plugin = Bukkit.getServer().getPluginManager().getPlugin("PLUGINNAME");
       
        if (player.hasPermission("perm.here")) {
           
            if (player.getItemInHand().getType() == Material.SLIME_BALL) {
               
                if (event.getAction() == Action.LEFT_CLICK_AIR) {
                   
                    final Item grenade = world.dropItem(player.getEyeLocation(), new ItemStack(Material.SLIME_BALL));
                    grenade.setVelocity(player.getEyeLocation().getDirection());
                    plugin.getServer().getScheduler().scheduleAsyncDelayedTask(plugin, new Runnable() {
 
                                @Override
                                public void run() {
                                    grenade.getWorld().createExplosion(grenade.getLocation(), 0.0F);
                                    grenade.remove();
                                }
                            }, 40L);
                }
            }
        }
    }
 
}

 

You need the onEnable and onDisable methods in this class (as it is the main class) also, because you're using events. You need to implement Listener aswell.

 

What Loogeh said, is what I did. Try using it.

 

If you don't know how to do that. These people have good tutorials.

Thanks again guys!

Ok, this now what I have for my MainClass:

Code:

package com.grenade.semtex;
 
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
     
public class MainClass {
     
        public final ListenerClass Listener = new ListenerClass();
   
        public void onEnable() {
         
            PluginManager pm = getServer().getPluginManager();
         
            pm.registerEvents(this.Listener, this);
         
            getLogger().info("Semtex is now enabled.");
         
        }
     
        public void onDisable() {
         
            getLogger().info("Semtex is now disabled.");
         
        }
     
    }
}

Here is what I have for my ListenerClass:

public class ListenerClass implements Listener {
 
      @EventHandler
      public void slimeGrenade(PlayerInteractEvent event) {
         
            Player player = event.getPlayer();
            World world = player.getWorld();
            Plugin plugin = Bukkit.getServer().getPluginManager().getPlugin("PLUGINNAME");
         
            if (player.hasPermission("perm.here")) {
             
                if (player.getItemInHand().getType() == Material.SLIME_BALL) {
                 
                    if (event.getAction() == Action.LEFT_CLICK_AIR) {
                     
                        final Item grenade = world.dropItem(player.getEyeLocation(), new ItemStack(Material.SLIME_BALL));
                        grenade.setVelocity(player.getEyeLocation().getDirection());
                        plugin.getServer().getScheduler().scheduleAsyncDelayedTask(plugin, new Runnable() {
   
                                    @Override
                                    public void run() {
                                        grenade.getWorld().createExplosion(grenade.getLocation(), 0.0F);
                                        grenade.remove();
                                    }
                                }, 40L);
                    }
                }
            }
        }
   
    }

Does it work?

 

Trying it right now

LOL, I forgot to make Plugin.yml

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

 

Haha :>

 

Hmmm, still doesn't work. Can it be in a file folder not a .jar?

let me show you my plugin.yml file

name: grenade.semtex
main: com.grenade.semtex.MainClass
version: 1

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

 

WinX-9 - The plugin.yml must be in the root directory of your project, the plugin name cannot have a '.'', either.
Check is out: http://wiki.bukkit.org/Plugin_YAML
