This is a two-machine Chinese chess game developed by MFP language with voice and video dialogue function. This game requires two players, each using a different Android device but running the same software. No central server is needed to play this game, two Android devices communicate peer-to-peer through TCPIP protocol or WebRTC protocol based on email address.
If the TCPIP protocol is used, it does not matter if there is a NAT layer between the two devices. But if there is a NAT layer, you must ensure that the server-side device starts the game first. When the game starts, it will display the IP address of the machine. The player who starts the game first must tell the other party the IP address of the machine, and then the player who starts the game enters the IP address of the first player to connect. If the connection is successful, the game will start.
If the WebRTC protocol based on email addresses is used for peer-to-peer communication, long-distance (thousands of kilometers) chess battles can be achieved. The process of starting the game is similar to using the TCPIP protocol. After the first player starts, wait for the second player to start and enter the email address of the first player to connect. If the connection is successful the game starts. But one thing is different from using the TCPIP protocol. When using the WebRTC protocol for point-to-point communication for the first time, you need to set the email address of the machine. When setting, you need to enter the email address and password (note that this password is the password used when sending and receiving emails using the SMTP and IMAP protocols, and it may not be the same as the password used to log in to the web page to check emails). If you are using Microsoft Outlook mailbox, Tencent QQ mailbox, Yahoo mailbox or Google Gmail mailbox, you don’t need to enter other information, otherwise you need to enter the server information of smtp and imap.
If the user is using the Microsoft Outlook mailbox, there is no need to do too many settings, and it can be used after entering the email address and password. But it should be noted that if the user frequently starts the game or switches the mobile network, Microsoft's outlook server may think that the user is sending spam, and will prevent the user from sending and receiving emails. In this case the user will receive an email asking to verify the account. The user needs to log in to the Outlook mailbox on the Microsoft website, follow the prompts to confirm that it was done by him, and then he can continue to use the Outlook mailbox;
If the user is using Google's gmail mailbox, when this application sends an email for the first time, it will be considered that the email comes from an insecure application (that is, an application that uses SMTP and IMAP protocols instead of using the paid Gmail API to send and receive emails) And was blocked. In this case, the user also needs to log in to the online gmail mailbox. According to Google's prompt, enable the access permission of the application with lower security, and then you can continue to use the gmail mailbox
; You don't need to do anything to play games or switch mobile networks.
Conversely, if the user starts the game frequently, it will cause frequent emails to Yahoo, and Yahoo mayrummyfb.in reject these emails as spam; No problem, please note that the password used by QQ mailbox to send and receive email through SMTP and IMAP protocols may be different from the password used to log in to web mailbox or QQ mailbox client.
As for other mailboxes, as long as they support SMTP and IMAP services and have no special security rules, they can be used as WebRTC addresses. The special security rules here mean that the email server will identify the email-sending software, sending address, and receiving address, and filter out some emails that the email server seems to be harmful or spam. For example, the user's email address is on the blacklist of the other party or the email server; for another example, NetEase's 163, 129 and neteast mailboxes provide smtp and imap services, but only allow well-known mail clients such as outlook or foxmail to send and receive mail , so NetEase's mailbox cannot be used.
After the user's webRTC address is successfully set, there is no need to change it, and two distant players can play chess as if they are in the same room at any time. After a successful connection, the video chat will also start. Players can play chess while chatting, and if they don't want to chat, they can turn off the video or voice. In short, this game is most suitable for leisure and entertainment with distant relatives and friends, killing time.
