Noob compilation question

So I'm not plugin maker but I've been trying to modify an old plugin to change something to my liking.

I have the .java file and it's been edited, but I can't figure out how to convert it to a .class to be used.

I've tried the javac way, but that just gives me errors about symbols.

Here's the code:

Code:java

package com.ownedcraft;
 
import java.util.HashMap;
import java.util.Map.Entry;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
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.event.player.PlayerMoveEvent;
import org.bukkit.event.player.PlayerQuitEvent;
 
public class CPListener implements Listener{
 
    private Main plugin;
 
    private HashMap<Player,Player> compassTargets;
 
    public CPListener(Main instance){
        plugin = instance;
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
        compassTargets = new HashMap<Player,Player>();
    }
 
    @EventHandler
    public void onLeave(PlayerQuitEvent e){
        for (Entry<Player,Player> entry: compassTargets.entrySet()){
            if (entry.getKey() == e.getPlayer()){
                compassTargets.remove(entry.getKey());
            }
            if (entry.getValue() == e.getPlayer()){
                entry.getKey().sendMessage(ChatColor.RED+"Your target has left the game, your compass is no longer tracking anyone.");
                compassTargets.remove(entry.getKey());
            }
        }
    }
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e){
        Player ply = e.getPlayer();
        Player targ = null;
        if (( (e.getAction().equals(Action.RIGHT_CLICK_AIR) || e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) && ply.getItemInHand().getType().equals(Material.COMPASS))){
 
            if (!ply.hasPermission("comptrack.track")) return;
 
            // Find the closest player to this player
 
            for (Player player: Bukkit.getOnlinePlayers()){
                if (ply.getWorld() != player.getWorld()) continue;
                if (ply == player) continue;
                if ( (targ == null) || ply.getLocation().distance(player.getLocation()) < targ.getLocation().distance(ply.getLocation())){
                    if (player.getLocation().distance(ply.getLocation()) <= 1) continue;
                    targ = player;
                }
            }
 
            if (targ == null){
                ply.sendMessage(ChatColor.RED+"Couldn't find a target!");
                return;
            }
 
            // Add set the compass location of this player, if a target was found
 
            ply.sendMessage(ChatColor.GRAY+"Targeting "+ChatColor.GREEN+targ.getName()+"!");
            compassTargets.put(ply,targ);
        }
        else if ( (e.getAction().equals(Action.LEFT_CLICK_AIR) || e.getAction().equals(Action.LEFT_CLICK_BLOCK)) && ply.getItemInHand().getType().equals(Material.COMPASS) ){
 
            if (!ply.hasPermission("comptrack.dist")) return;
 
            if (compassTargets.get(ply) != null){
                ply.sendMessage(ChatColor.GREEN+"Your target is "+ply.getLocation().distance(compassTargets.get(ply).getLocation())+" blocks away.");
            }
            else {
                ply.sendMessage(ChatColor.RED+"Your compass isn't tracking anyone!");
            }
        }
 
    }
 
    @EventHandler
    public void onMove(PlayerMoveEvent e){
 
        if (compassTargets.get(e.getPlayer()) != null){
            e.getPlayer().setCompassTarget(compassTargets.get(e.getPlayer()).getLocation());
        }
 
        for (Player ply: Bukkit.getOnlinePlayers()){
 
            Player compassTarget = compassTargets.get(ply);
 
            if (compassTarget == e.getPlayer()){
                if (ply.getWorld() == e.getPlayer().getWorld()){
                    if (ply.getLocation().distance(e.getPlayer().getLocation()) <= 1){
                        ply.sendMessage(ChatColor.GREEN+"Your target is close.");
                        compassTargets.remove(ply);
                    }
                    ply.setCompassTarget(e.getPlayer().getLocation());
                }
                else {
                    ply.sendMessage(ChatColor.RED+"Your target has changed world, and is no longer available.");
                    compassTargets.remove(ply);
                }
            }
        }
 
    }
 
}
 

It's from an old plugin called CompassTracker.

To compile it you may need all of the source files, plugin.yml and config.yml in an application environment from which you can compile (I recommend eclipse). In there you need to reference the Bukkit API and JavaDocs then do what you want to edit.

Ahhh, that's what I was thinking it was, normal cmd javac won't get the minecraft stoof.

Thank-you, gonna try learning to make plugins soon

 

use eclipce
try again
