How to make a Block Shoot Arrows?

I'm trying to make a plugin where you right click the ground with a wood-shovel and you can select to place an archer tower, and that archer tower can shoot arrows at mobs and displays its name and level. But I can't seem to figure out how to make my archer tower shoot arrows.(This could be done by attaching the blocks of the archer tower to a class I don't know)

Main.java

Code:

package com.mattjuior.towerdefense;

import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

import com.mattjuior.towerdefense.commands.Placer;
import com.mattjuior.towerdefense.events.PlacerClick;

public class Main extends JavaPlugin {
    public void onEnable(){
        getCommand("placer").setExecutor(new Placer());
       
        registerEvents();
    }
   
    public void registerEvents() {
        PluginManager pm = getServer().getPluginManager();
       
        pm.registerEvents(new PlacerClick(), this);
    }
   
}

Placer.java

Code:

package com.mattjuior.towerdefense.commands;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;

public class Placer implements CommandExecutor{

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (!(sender instanceof Player)) {
            sender.sendMessage("You must be a player to enter this command!");
            return false;
        }
       
        Player player = (Player) sender;
        if (player.hasPermission("MTD.placer")) {
        player.getInventory().addItem(new ItemStack(Material.WOOD_SPADE));
        return true;
        }else {
            player.sendMessage(ChatColor.RED + "You do not have permission!");
            return false;
        }
    }

}

PlacerClick.java

Code:

Please Help!

 

World has a method for spawning entities at a certain location: So you can spawn arrow entities at a certain location (ex. slightly above or in front of your 'tower block'). After spawning the projectile, you can assign it a certain velocity to make it fly in the wanted direction.

So all you need to store somewhere is the location of your 'tower blocks'.

 

Thanks Ill try that!

Where/How would you store the location of all of the archer tower blocks?

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

 

@mattyj1231 You can store the locations of your tower in a config file, or in an Array or Hash map.

 

Ok I'll see how that works
