how do ppl make those multiplayer game for an example in opengl. how do they like send the stuff going on at the server to the clients and client1 do something then send to server then server send to all client to change the stuff that client1 made?? how do they send all that and make changes to the vertex and fragments?
do they rapidly get and change the vertex position/fragment? or they made like something on the server that change stuff then they rapidly get signal from the client and do the changes or no?
