Example tutorial on how to improve game UDP transmission in win7

UDP transmission of win7 games often appears in some unpopular Internet games or online games. It will affect people’s transmission speed. If the speed is too slow, the game interface, sound, etc. will freeze. We can Use the following code to design game UDP transmission. Let’s take a look at it below.

win7 game UDP transmission optimization technology:

1. Coordinator Receive

1. First, we need to use a word processing tool to open the environment variables of the game.

2. Then type the following code:

packagecom.heima.socket;

importjava.io.IOException;

importjava.net.DatagramPacket;

importjava.net.DatagramSocket;

publicclassDemo02_Receive{

publicstaticvoidmain(String[]args)throwsIOException{

DatagramSocketsocket=newDatagramSocket(6666);//Create Socket is equivalent to creating a port

DatagramPacketpacket=newDatagramPacket(newbyte[1024],1024);//Creating Packet is equivalent to creating a shipping container

while(true){

socket .receive(packet);//Pick up the goods and get the data

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

intlen=packet.getLength();// Get a reasonable number of bytes

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

intport=packet.getPort();//Get the port

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

}

}

}

2. Send

#1. Similarly, we need to use a word processing tool to open the environment variables of the game.

2. Then enter the following code:

packagecom.heima.socket;

importjava.io.IOException;

importjava.net.DatagramPacket;

importjava.net.DatagramSocket;

importjava.net.InetAddress;

importjava.util.Scanner;

publicclassDemo02_Send{

publicstaticvoidmain (String[]args)throwsIOException{

Scannersc=newScanner(System.in);//Create computer keyboard entry target

DatagramSocketsocket=newDatagramSocket();//Creating Socket is equivalent to creating Port

while(true){

Stringline=sc.nextLine();//Get the string array entered by the computer keyboard

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

break;

}

DatagramPacketpacket=//Creating a Packet is equivalent to a shipping container

newDatagramPacket(line.getBytes(),line .getBytes().length,

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

socket.send(packet);//Arrange delivery and transfer data information Get out

}

socket.close();

}

}
