Solved Server Ping "Ping"

Hey Guys,
I have a tough nut for you to crack today.
So, here is the jiff.
When a MC client pings a server, it says the latency between the client and the server.
How might I get the integer of the ping latency between client and server?
I figure you have to have the server ping the client, when ServerListPingEvent is called.
I don't want to do it one they join, I went to ping them before they join.
I know there is stuff on pinging with java on the internet, but it is kinda useless, since it depends on the os's command line.

Please help (Thanks!),

Code:java

final Player p = (Player) sender;
int ping = ((CraftPlayer)p).getHandle().ping

You'd have to update the plugin every Minecraft update as this does use NMS.

or you can use reflection

 

BlueMustache As my fellow posters have pointed out, there is no way to measure ping before the client has an actual Player to send keepalive packets to (which include timestamps on which the ping is based).

So, there is no way at all, outside of having an established connection?

We can make super-colliders that are powered by homeless people on treadmills, and we can't do this? :/

 

I don't think all can help you, but anyway why do you need it before the player joins?

 

BlueMustache

Because the client doesn't specify a way to respond to a packet that would allow you to effectively ping a server, although you could create a modified client that sends a packet to the server, and a Bukkit plugin to respond to it.

To help my plugin... run a few numbers.

 

And why can't those numbers be ran on login?

Why not before? Time Dr.Freeman?

 

Not before because you can't do it before.

 

BlueMustache http://wiki.vg/Protocol#Status There is S -> C and a reply, if you want ping, figure out how to get it from there.

Thanks.
I guess it's solved as much as it possible can be.
