config.yml

what's te best code to check that Config.yml exists or not?

 

depends on what you call the best, fast or easy to understand or nice to look

 

just a way

 

haha alright... heres what I use to create my config.yml (checks if it exists)

Code:

public class Flow extends JavaPlugin {
    @Override public void onEnable() {
        final File f = new File(getDataFolder(), "config.yml");
        if (!f.exists()) {
            saveDefaultConfig();
        }

 

thanks!!
btw do you know how to change the config file on a command
like change:

Code:

Kick: false

to

Code:

Kick: true

on a command

 

this.getConfg().set("Kick",true);

 

ferrybig knows everything.... hes beat me to like 5 answers today haha.

 

do you know how to get if it is true or false
i am doing this but it doen't work

Code:

if (plugin.getConfig().getBoolean("Kick") == true) {
 
}

 

why it dont work?

 

it tells me "could not pass PlayerJoinEvent"

here is the rest on my code if you need it:

Code:

public class LoginMessage extends JavaPlugin {
    public static LoginMessage plugin;
 
    @Override
    public void onEnable() {
        super.onEnable();
 
        final File f = new File(getDataFolder(), "config.yml");
        if (!f.exists()) {
            saveDefaultConfig();
        }
 
        getServer().getPluginManager().registerEvents(new Listener() {
            @SuppressWarnings("unused")
            @EventHandler
            public void playerJoin(PlayerJoinEvent event) {
                Player player = event.getPlayer();
                if (plugin.getConfig().getBoolean("Kick") == true) {
                    if (player.isOp()) {
                        return;
                    } else {
 
                        String output = ChatColor.translateAlternateColorCodes(
                                '&', getConfig().getString("KickMessage"));
 
                        player.kickPlayer(output);
                    }
 
                } else {
                    return;
                }
            }
        }, this);
    }
 
    @Override
    public void onDisable() {
        super.onDisable();
    }
 
    @Override
    public boolean onCommand(CommandSender sender, Command command,
            String label, String[] args) {
        Player player = (Player) sender;
 
        if (label.equalsIgnoreCase("k")) {
            if (args.length == 1) {
                if (args[0].equalsIgnoreCase("on")) {
                   
                    this.getConfig().set("Kick",true);
                    player.sendMessage("The server will now kick the players that whant to join");
                } else if (args[0].equalsIgnoreCase("off")) {
                   
                    this.getConfig().set("Kick",false);
                    player.sendMessage("The server will now let players enter");
                }
            }
        }
 
        return super.onCommand(sender, command, label, args);
    }
}

 

what is the stack trace?
to whits line is the stack trace pointing?
{edit} cause: plugin = null, you forgot to do plugin = this inside onEnable()

 

line 31

 

see my edit, if you didn;t see it already

 

it is

Code:

plugin = new LoginMessage();

isn't it?

 

add the following to the onEnable methode

Code:java

plugin=this;

 

k

i have never done that.

btw: i think you are a plugin god
