Checking a players IP on login.

I have Bungee network setup and I'm trying to add a plugin to only allow people to connect through the Bungee Proxy (I know you can block the port with firewall but its no currently an option for myself)

I have tried this code but I am getting a null pointer exception:

Code:

    @EventHandler
    public void  onPlayerLoginEvent(PlayerLoginEvent e){
        Player p = e.getPlayer();
        if(p.getAddress().getHostName().equalsIgnoreCase("127.0.0.1")){
            e.disallow(Result.KICK_OTHER, "You must connect via the portal hub.");
        }
 
}

Here is the error:

 

NullPointerException.

Something is null, either it is the address, or the player.

 

Thanks for your reply but I theres no indication as to the root of the problem.

**shrugs** neither to i, and yet my console is spammed by errors from my ElementalSwords plugin .

Debuging is hard.

So, stop going "OH MY GOSH OH MY GOSH ITS AN ERROR!", and work through the problem

It is the check IP thing.

Something to do with their IP is null

Here is the method i use:
@EventHandler
public void onplayerjoin(PlayerJoinEvent event)
{
String pn = event.getPlayer().getName();
String pi = event.getPlayer().getAddress().toString().replaceAll("/", "").split(":")[0];
}

From there you can do whatever with the ip by using the string pi. The formating is needed otherwise you will get: /ip : port
i made it so you just get the ip.

So you can do:
public void onplayerjoin(PlayerJoinEvent event)
{
Player p = event.getPlayer();
String pi = event.getPlayer().getAddress().toString().replaceAll("/", "").split(":")[0];

if(pi.equals("127.0.0.1"))
{
event.disallow(Result.KICK_OTHER, "You must connect via the portal hub.");
}
}


gl with what your doing
