onPlayerChat (AsyncPlayerChat) not firing?

Hey, im trying to create a plugin for something that will respond to certain messages, but I don't think onPlayerChat is firing, I've added a system.out.println to it but it returns nothing in console, can anyone help?

Code:

@EventHandler
public boolean onPlayerChat(AsyncPlayerChatEvent event) {
    System.out.println("test");
    Player p = event.getPlayer();
    String msg = event.getMessage();
    if (msg.toLowerCase().equals("potatobot")) {
        if (p.hasPermission("potatobot.use")){
        Player online = null;
        for (Entity en : Bukkit.getOnlinePlayers())
            if (en instanceof Player) {
                online = (Player) en;
                online.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "Yes, Master?");}
        }}
    if (msg.toLowerCase().startsWith("potatobot") && msg.toLowerCase().contains("tell a joke")) {
        if(p.hasPermission("potatobot.use")){
        Player onlinea = null;
        for (Entity en : Bukkit.getOnlinePlayers())
            if (en instanceof Player) {
                onlinea = (Player) en;
                Random rand = new Random();
                int randomNumber = rand.nextInt(5);
                    //yes, ignore the really bad jokes, they came from the internet.
                    if (randomNumber == 1)
                        onlinea.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "Whats red and bad for your teeth? A brick!");       
                    if (randomNumber == 2)
                        onlinea.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "Why was 6 afraid of 7? Because 7 8 9!");       
                    if (randomNumber == 3)
                        onlinea.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "What do you call a pig that does karate? A Pork Chop!");       
                    if (randomNumber == 4)
                        onlinea.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "What do computers eat for lunch? Microchips!");                   
                    if (randomNumber == 5)
                        onlinea.sendMessage(Color.GRAY + "[" + Color.BLUE + "Robot" + Color.GRAY + "]" + Color.SILVER + "PotatoBot" + Color.WHITE + "How do trees access the internet? They log in!");                   
        }           
            }}

    return true;}}

 

@mysterypotatoguy Did you register the event?

 

@AdamQpzm I think so? where would I find it?
EDIT: If you mean
public final class PotatoBot extends JavaPlugin implements Listener {
then yes

 

@mysterypotatoguy Well, no. You need to actually register it using PluginManager#registerEvents(Listener, Plugin).
Look here for reference: http://wiki.bukkit.org/Event_API_Reference#Registering_Events

 

@Rocoty It works! Thank you!
