Tutorial on how to optimize game UDP transmission for Win7

UDP transmission of win7 games often appears in some niche online games or online games. It will affect our transmission speed. If the speed is too slow, the game screen, sound, etc. will freeze. We can use the following The code optimizes game UDP transmission. Let’s take a look at it below.

win7 game UDP transmission optimization tutorial:

1. Receiver Receive

1. First, we need to use a text editing tool to open the game configuration file.

2. Then enter the following code:

package com.heima.socket;

import java.io.IOException;

import java.net. DatagramPacket;

import java.net.DatagramSocket;

public class Demo02_Receive {

public static void main(String[] args) throws IOException {

DatagramSocket socket = new DatagramSocket(6666); // Creating a Socket is equivalent to creating a dock

DatagramPacket packet = new DatagramPacket(new byte[1024], 1024); // Creating a Packet is equivalent to creating a container

while (true) {

socket.receive(packet); //Receive goods and receive data

byte[] arr = packet.getData(); //Get data

int len ​​= packet.getLength(); // Get the valid number of bytes

String ip = packet.getAddress().getHostAddress(); // Get the ip address

int port = packet.getPort(); // Get the port number

System.out.println(ip ":" port ":" new String(arr, 0, len));

}

}

}

2. Send

1, the same We need to use a text editing tool to open the game's configuration file.

2. Then enter the following code:

package com.heima.socket;

import java.io.IOException;

import java.net. DatagramPacket;

import java.net.DatagramSocket;

import java.net.InetAddress;

import java.util.Scanner;

public class Demo02_Send {

public static void main(String[] args) throws IOException {

Scanner sc = new Scanner(System.in); // Create keyboard input object

DatagramSocket socket = new DatagramSocket(); // Creating a Socket is equivalent to creating a dock

while (true) {

String line = sc.nextLine(); // Get the string entered by the keyboard

if ("quit".equals(line)) {

break;

}

DatagramPacket packet = // Create a Packet equivalent to a container

new DatagramPacket(line.getBytes(), line.getBytes().length,

InetAddress.getByName("127.0.0.1"), 6666);

socket.send (packet); // Ship, send the data out

}

socket.close();

}

}
