Shooting fireballs?

Hello, Im new to coding and I have a problem, everything in the plugin works ok, but when I try to right click with the book, it doesn't shoot the fireball. Any help?

Code:java

package lolwut.harrymoo.testplugin;
 
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Fireball;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin {
 
    public void onEnable() {
        getLogger().info("Plugin enabled!");
    }
    public void onDisable() {
        getLogger().info("Plugin Disabled!");
    }
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (label.equalsIgnoreCase("fireball")) {
            Player player = (Player) sender;
            PlayerInventory inventory = player.getInventory();
            inventory.addItem(new ItemStack(Material.BOOK));
            player.sendMessage(ChatColor.GOLD + "Fireball!");
        }
        return false;
    }
    @EventHandler
    public void OnEvt(PlayerInteractEvent event) {
    Player player = event.getPlayer();
    if (player.getItemInHand().getType() == Material.BOOK && event.getAction() == Action.RIGHT_CLICK_AIR) {
        player.launchProjectile(Fireball.class);
        }
    }
}

this is what i used to shoot a fireball:

Code:

                    Location spawnAt = player.getEyeLocation().toVector().add(player.getEyeLocation().getDirection().multiply(3)).toLocation(player.getWorld());
                    Fireball fireball = player.getWorld().spawn(spawnAt, Fireball.class);

 

IkBenHarm ok, i'll try it out.
Edit: nothing

 

harrybridgen
ohno, wait. this was it. Sorry

Code:

double pitch = ((player.getLocation().getPitch() + 90) * Math.PI) / 180;
                    double yaw = ((player.getLocation().getYaw() + 90) * Math.PI) / 180;
 
                    double x = Math.sin(pitch) * Math.cos(yaw);
                    double y = Math.sin(pitch) * Math.sin(yaw);
                    double z = Math.cos(pitch);
 
                    Vector vector = new Vector(x, z, y);
                   
                    Location spawnAt = player.getEyeLocation().toVector().add(player.getEyeLocation().getDirection().multiply(3)).toLocation(player.getWorld());
                    Fireball fireball = player.getWorld().spawn(spawnAt, Fireball.class);
                    fireball.setDirection(vector.multiply(10));

for that vector thing you might aswell use player.getlookingdirection

harrybridgen
you might wanna change getItemInHand().getType ==
to
getItemInHand().getType().equals

IkBenHarm Nothing again. I think there is a problem with my code

Code:java

 @EventHandler
    public void OnEvt (PlayerInteractEvent event) {
    Player player = event.getPlayer();
    if (player.getItemInHand().getType() == Material.BOOK && event.getAction() == Action.RIGHT_CLICK_AIR) {

just gives me errors and shit

harrybridgen
mh, try removing the book check and see if its shoots a fireball then. if it does, you know where the error is

 

harrybridgen Okay, nothing he said is of value here. You need to let your main class implement listener

Code:java

public class <classname> extends JavaPlugin implements Listener

then you need to register events in your onEnable.

Code:java

Bukkit.getPluginManager().registerEvents(this, this);

 

d3v1n302418 How do I use

Code:java

Bukkit.getPluginManager().registerEvents(this, this);

 

d3v1n302418
whoops... *Using a drill to nail myself at the wall right now*

 

IkBenHarm And no, still nothing.

 

harrybridgen
it's what d3v1n302418 said. I forgot to look at that

 

How do I use IkBenHarm

Code:

Bukkit.getPluginManager().registerEvents(this, this);

Where do I put it?

 

harrybridgen
onEnable(){
// here
}

 

IkBenHarm It works! Thanks

 

Using the main class as your listener #swag
