Setting an Arrow's Velocity

So I'm trying to make an arrow into a "Gun like" bullet and i'v looked around on the forums and not found much help. I want the arrow to move much faster and be a 2 hit kill.
Here's my code:

Code:java

package net.notscast.kitpvp;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.entity.Arrow;
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.plugin.java.JavaPlugin;
import org.bukkit.util.Vector;
 
public class Main extends JavaPlugin implements Listener{
@Override
public void onEnable(){
getLogger().info("NotsCast KITPVP by z6tanker is now running :)");
getServer().getPluginManager().registerEvents(this, this);
this.saveDefaultConfig();
}
@Override
public void onDisable(){
getLogger().info("NotsCast KITPVP by z6tanker is now disabled Goodbye! :(");
}
@EventHandler
public void onPlayerInteractEvent(PlayerInteractEvent event){
Player player = event.getPlayer();
if(player.getInventory().getItemInHand().getType() == Material.BLAZE_ROD){
if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK){
player.sendMessage(ChatColor.BLUE + "POW!");
player.launchProjectile(Arrow.class);
}
}
}
}
 
 

Thanks, z6

 

Arrow a = p.launchProjectile(Arrow.class);
a.setVelocity(yourvector);
