#

a while ago, i played around a bit boost to make a small async tcp server bc i wanted to try out boost.

for my uni i had to create a game in rust. as the final project (we can do anything we want), i want to try adding multiplayer to it.

i already have a way of sending data to my rust client and back.

i am just not sure how to send key info (up, left, down, right) over the network? when i press my left arrow, it says "^[[C" but does not send the message until i press enter....i could clear that string and send it to the rust client to do something in the game...(but i am not sure if every operating system etc sends "^[[C" if i press left arrow)

any ideas?

It depends on your enviroment if you are using linux AFAIK

I think there's no general way to do that

I believe you need to disable "canonical mode" in the terminal: https://viewsourcecode.org/snaptoken/kilo/02.enteringRawMode.html

that worked! thanks! i tried connecting with nc localhost 1234 but it didnt work

this did the trick for making it work with writing my own client using what is present in the website and not using nc or telnet for connecting or something
