            How do multiplayer javascript games communicate with servers?
            Asked 2021-Apr-22 at 15:33

            how do online javascript games like, and all the other ".io" games communicate with their servers? I opened the Network tab on google chrome but no requests were there. Does google chrome hide these requests or do these websites use a different protocol?



            Answered 2021-Apr-22 at 15:33

            Most likely WebSockets. For example, in if you go into the chrome network tab you can see a WebSocket request:

            Clicking on it we see the following WebSocket packets being transmitted and receieved:

            The green being transmitted packets, and the red being received packets. If you click on one of those packets you can see a hex dump of the packet. If you want to learn more about WebSockets you can go here. A good WebSocket library is which you can learn about here.



            Choppy online python game
            Asked 2021-Mar-15 at 17:49

            I have programmed a simple clone of in python using pygame and sockets and I have three problems:

            1. When I play the game alone on my laptop the game is choppy. Every ten seconds my game get stuck for a while (one milisecond) and then continue. It's not a big problem but it's annoying.
            2. When I play on two computers in my local network, I see the other player (the other snake) is also choppy.
            3. The strangest problem is when I run my server on my main laptop and then run the game on my second laptop the game starts and after few seconds crash. Debugger on client says that pickle data was truncated while receiving data from the server. But when I run the server program on my second laptop and the game on my main laptop everything is OK. Why?

            I tried:
            Problem 1. change FPS on the client and time.sleep on the server
            Problem 2. change time.sleep on the server
            Problem 3. change the input value of recv() method

            Server code:



            Answered 2021-Mar-15 at 17:49

            Your third problem (truncated pickle data) is because you are using TCP, and you are unpickling whatever recv returns. You might be thinking that whenever you send something, and the receiver calls recv, returns the exact same thing, but actually it doesn't. TCP splits your data up into packets, so the receiver might not receive all the data at the same time.

            For example, if you send "abcdefgh" and then separately send "ijkl", it's allowed for the first receive to return "abcd" and the second to return "efghijkl". Or the first one could return "ab" and the second one could return "cde" and the third one could return "fghijkl", or so on.

            You have to design a way for the receiver to know when to stop receiving. For example, if you sent "8abcdefgh" and then "4ijkl", the receiver could get "8abcdefgh4ij", and then it knows "8abcdefgh" is one "send" (because it starts with 8 and then 8 more bytes) and it knows the "4ij" is the beginning of the next "send" but it's not the whole thing (because it starts with 4 but there aren't 4 more bytes).

            Another way is to send a special character like a newline (enter key) after each message. This probably doesn't work with pickles because pickles can have newlines in them. But you could choose another byte that pickles don't have, like 0xFF. Then the receiver knows to keep on receiving until it sees the byte 0xFF.

            How do I keep a div center when browser window goes smaller than div size?
            Asked 2020-Sep-25 at 16:00

            Essentially when the browser window goes larger thh div stays centered and creates white space on the outside. I want the same thing to happen when the browser window goes smaller. I want to see less of the div but keep it centered. At the moment I see less of the div but the left side locks so I end up only seeing a slither of the left part of the image (instead of the center). Sorry if this is a convoluted way of asking I am new to programming. Any help would be massively appreciated! Thanks in advance! :)

            p.s I am also struggling to have the video playing if anyone can help with that too

            Here is my code currently

            Am trying to show the 'You loose like the looser you are looser' text after the small moving rectangle hits the bounderies... but instead, the rectangle is moving past the bounderies and the 'You loose' text only shows up after i hit a random button... the code is below



            Answered 2020-Aug-27 at 13:47

            Right now you are only executing your collision code if there is a certain event because it is indented inside of the event loop, so it only happens if there is an event, in your case key press.

            I've started a panic with my index out of range, and I can't get out
            Asked 2020-May-29 at 08:17

            I'm writing this program to become comfortable with types (not objects!).

            The basic premise is the user enters an animal name (cow, snake bird), then an action (eat, move, sound.) My code then looks it up and returns the value.

            So, the user entry is suppose to be on ONE line separated by a " ". I use strings.Split.

            I'm getting a "panic" notice when the user only enters a single char. I'm thinking this panic arises out of the compiler trying to "split" a single char.

            TWO Questions: 1. Am I right? 2. How do I fix it?



            Answered 2020-May-29 at 01:58

            Create the scanner outside the loop to avoid discarding buffered data. Break when Scan() returns false. Check for and handle invalid input.
