2. Addon Commands & Events

Addon Commands

Addon commands should be registered through the registerCommand method in the onAddonEnable method. Addon commands will appear as subcommands for the /breweryx command in-game.

Java

MyCommand.java

public class MyCommand implements AddonCommand {
    @Override
    public void execute(BreweryPlugin breweryPlugin, Lang lang, CommandSender sender, String label, String[] args) {
        sender.sendMessage("Hello, from MyCommand!");
    }

    @Override
    public List<String> tabComplete(BreweryPlugin breweryPlugin, CommandSender sender, String label, String[] args) {
        return null;
    }

    @Override
    public String getPermission() {
        return "brewery.myaddon.command";
    }

    @Override
    public boolean playerOnly() {
        return false;
    }
}

@Override
public void onAddonEnable() {
    registerCommand("mycommand", new MyCommand());
}

Kotlin

MyCommand.kt

class MyCommand : AddonCommand {
    override fun execute(breweryPlugin: BreweryPlugin, lang: Lang, sender: CommandSender, label: String, args: Array<String>) {
        sender.sendMessage("Hello, from MyCommand!")
    }

    override fun tabComplete(breweryPlugin: BreweryPlugin, sender: CommandSender, label: String, args: Array<String>): List<String>? {
        return null
    }

    override fun getPermission(): String {
        return "brewery.myaddon.command"
    }

    override fun playerOnly(): Boolean {
        return false
    }
}

override fun onAddonEnable() {
    registerCommand("mycommand", MyCommand())
}

Events in addons

Events in addons should be declared the same way as they are in normal Bukkit plugins. The only difference being, is that you must register them through your addons registerListener method in the onAddonEnable method.

Java

MyListener.java

public class MyListener implements Listener {
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
        event.getPlayer().sendMessage("Hello, from MyListener!");
    }
}

@Override
public void onAddonEnable() {
    registerListener(new MyListener());
}

Kotlin

MyListener.kt

class MyListener : Listener {
    @EventHandler
    fun onPlayerJoin(event: PlayerJoinEvent) {
        event.player.sendMessage("Hello, from MyListener!")
    }
}

override fun onAddonEnable() {
    registerListener(MyListener())
}
