Firework Hit

I'm working on a Railgun plugin which means, clicking a hoe will shoot fireworks and if it hits/goes very close to an entity it will kill them. Does anybody have an idea on how I would be able to accomplish this?

Code:java

package me.Jaaakee224.RailGun;
 
import java.lang.reflect.Method;
import java.util.Random;
 
import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.Sound;
import org.bukkit.block.Block;
import org.bukkit.entity.Firework;
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.plugin.java.JavaPlugin;
 
public class RailGun extends JavaPlugin implements Listener {
 
int timer,id = 0;
Random gen = new Random();
public void onEnable(){
this.getServer().getPluginManager().registerEvents(this, this);
}
 
@SuppressWarnings("deprecation")
@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
if ((event.getAction() == Action.RIGHT_CLICK_AIR) || (event.getPlayer().getItemInHand().equals(Material.WOOD_HOE))) {
// event.getPlayer().playSound(event.getPlayer().getLocation(), Sound.BLAZE_DEATH, 1, 9);
event.getPlayer().playSound(event.getPlayer().getLocation(), Sound.BLAZE_HIT, 2, 50);
try {
for(Block loc:event.getPlayer().getLineOfSight(null, 100)) {
playFirework(loc.getLocation());
 
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
 
private Object[] dataStore = new Object[5];
public void playFirework(Location loc) throws Exception {
Firework fw = (Firework) loc.getWorld().spawn(loc, Firework.class);
if(dataStore[0] == null) dataStore[0] = getMethod(loc.getWorld().getClass(), "getHandle");
if(dataStore[2] == null) dataStore[2] = getMethod(fw.getClass(), "getHandle");
dataStore[3] = ((Method) dataStore[0]).invoke(loc.getWorld(), (Object[]) null);
dataStore[4] = ((Method) dataStore[2]).invoke(fw, (Object[]) null);
if(dataStore[1] == null) dataStore[1] = getMethod(dataStore[3].getClass(), "addParticle");
((Method) dataStore[1]).invoke(dataStore[3], new Object[] {"fireworksSpark", loc.getX(),loc.getY(),loc.getZ(),gen.nextGaussian() * 0.05D, -(loc.getZ()* 1.15D) * 0.5D, gen.nextGaussian() * 0.05D});
fw.remove();
}
private Method getMethod(Class<?> cl, String method) {
for(Method m : cl.getMethods()) if(m.getName().equals(method)) return m;
return null;
}
}

All help is appreciated

Jaaakee224 already looked at the quake plugin?

Thats what i got from the quake plugin

JordyPwner The code I gave is already working, meaning it shoots the line of effects exactly like Hypixel's. I don't want to copy from another plugin on Bukkit.

Wait 24 hours to bump.

Also, you've already copied the entire idea from another plugin, what's a little code? That being said, you can check every so often if a firework is near an entity, and if it is, kill it.

This isn't going into anything minigame related and this plugin won't be released. I'm just doing this for good practice.

 

Jaaakee224

I never said anything about a minigame or releasing this? Look at the solution I gave you.

 

mythbusterma
Once I get home I will test this out. Sorry for the confusion last reply. Only reason I am copying this is to see if I can even do it. Challenging myself
