ISP_CNN

thats the new connection packet (I think).

whenever that packet is received, send a MST with the data "/msg $username has connected."

I guess we need a bit more info on how you are writing this app. What language are you writing it in, are you using any kind of insim library?

Also, the connection packet you are looking for is IS_NCN. Your insim application connected to a server will receive this when a new user connects to the server (not joins the game, btw).

Right now, there is a message the server sends to all connections notifying them that user 'x' connected. You want to send more information of that kind to everyone?

There are plenty of examples of C# apps already around. Check out the LFSLib.NET posts as sdether has already posted a bunch of example applications.

Here is an app, its based off of a different insim app I made. It's python, and has a few bugs, so just ignore the console output.


from socket import *
import struct
import string
import threading
import time
import math
import winsound
import random
import array

global s
global data
global msgs
msgs = []
global conntry
conntry = 0
s = socket()
insim_admin = ""
insim_ip = "127.0.0.1"
insim_port = 7776
insim_name = "MsgApp"

class InSimRecv(threading.Thread):
    
    def kill(self):
        self.killed = True
        
    def run(self):
        while 1:
            InSimData = s.recv(4096)
            InSimHeader = InSimData[0:3]
            if InSimData:
                if int(struct.unpack("B", InSimData[1])[0]) == 3:
                    s.send(struct.pack("BBBB", 4, 3, 0, 0))    #Send ACK
                if struct.unpack("B", InSimData[1])[0] == 18:
                    s.send(struct.pack("BBBBBBBB63sB", 72, 14, 0, 0, int(struct.unpack("B", InSimData[3])[0]), 0, 0, 0, "Welcome to the server, connection #" + str(int(struct.unpack("B", InSimData[3])[0])) + " !", 0))

    def run(self):
        #s.send(struct.pack("BBBB", 4, 3, 0, 0))    #Send ACK
        time.sleep(15)
    
    def kill(self):
        self.killed = True

class InSimConnect(threading.Thread):
    def run(self):
        conntry = 0
        while conntry < 5:
            try:
                conntry=conntry+1
                print "Connecting to " + insim_ip + " on port " + str(insim_port) + "(" + str(conntry) +  "/5)"
                s.connect( ("127.0.0.1", 777) )

            except:
                print "Connection Failed!"
                pass

        time.sleep(1)
            
        try:
            s.send(struct.pack("BBBBhhBsh16s16s", 44, 1, 0, 0, 0, 32, 0, "!", 10, insim_admin, insim_name))
            s.send(data)

            time.sleep(1)
            
            InSimRecv().start()

            s.send(struct.pack("BBBB64s", 68, 13, 0, 0, "/msg ^5wheel4hummer\'s message app started."))

        except:
            print "Unknown Error"
            pass
                
        if conntry < 999:
            print "All connection attempts failed!"

InSimConnect().start()
