The entire section of code:

        plugin.setScoreboard(e.getPlayer());
        Player p = e.getPlayer();

                    String prefix = plugin.chat.getPlayerPrefix(p);
                    prefix = prefix.concat(pName);

                    String message = plugin.getconfig().getString("Messages.Groups." + plugin.permission.getPrimaryGroup(p) + ".join-message", "%player% &ejoin the game!");
                    message = message.replaceAll("%player%", pName);
                    message = ChatColor.translateAlternateColorCodes("&".charAt(0), message);

            }else{
                String message = plugin.getconfig().getString("Messages.Default.join-message", "%player% &ejoin the game!");
                message = message.replaceAll("%player%", p.getName());
                message = ChatColor.translateAlternateColorCodes("&".charAt(0), message);
                e.setJoinMessage(message);
            }
           
        }else{
            e.setJoinMessage(null);
        }
    }

 

Messages.enable is not set in your config, so it is returning null.

 

It is set in the config

Code:

Messages:
  #Enable join/quit/leave message.
  enable: true
  #Enable Group join/quit/leave message.
  #Players have colorful names by their group
  enableGroups: true
  #Message sent to players when they join
  welcome-message: 'Welcome to server.'

If you use this and it works:

Code:

boolean enable = plugin.getconfig().getBoolean("Messages.enable", true);
if(enable){
}

 

The plugin variable in the ConfMsfBooleanSetings class is null...you never gave it a value.

I suggest a constructor to which you pass the instance of your main class as a parameter

 

Added constructor and still does not work

 

I tried this but does not work. He did not know anyone please?

Code:

public void reloadConfiguration() {
        if (!new File(getDataFolder() + File.separator + "config.yml").exists()) {
              saveDefaultConfig();
            }
            try{
              reloadConfig();
            } catch (Exception e) {
              e.printStackTrace();
            }
           
            ConfMsfBooleanSetings s = new ConfMsfBooleanSetings();
            s.setEnablemessage(Boolean.valueOf(getConfig().getBoolean("Messages.enable")));
    }

Code:

public class ConfMsfBooleanSetings {
    ConfigurableMessages plugin;
    public Boolean enablemessage = Boolean.valueOf(true);
       
        public Boolean getEnablemessage() {
        return this.enablemessage;
    }
    public void setEnablemessage(Boolean enablemessage) {
        this.enablemessage = enablemessage;
    }
}
