I give up, it works slow, and I don't understand why, I mean, when I make a localhost test, it works smoothly, but when trying with another pc over lan, it lags a lot...

here is the code:

set_tcp_nodelay is done outside...

              }

              
            }catch(IOException ioe){}
    }

class Information contains a matrix of 6x5 integers.

so, what am I doing wrong here?

thanks for your help.

bye

PD: I read the two generals problem...just...wow..

there's a lot of lag, I mean, the game works at an "good" speed for like 2 seconds and then it lags for some milliseconds...like so...

it doesn't do just 6 updates per frame, it does all the necessary updates per frame, the only thing is that it only sends 6 commands per frame because is the maximum number of commands a player can make at the same time (for example, you can select 6 units at the moment, and send them to do something) I added the tcpnodelayoption and works faster, even so, is still very slow... I'm going to explain in detail what I'm doing so you can help me... every time the client gives a unit a new order, that order is stored on the Information object. on the principal thread, client and server are always sending and receiving data, so, in this case, server receives this information object, processes it, and returns it back to the client... this happens every step, is this causing the game to be slow? it's very frustating you know...

So, I have another question! I want to show you what's the client sending to the server and viceversa: the client sends an object called information, with a matrix of 6*5. 6 being the maximum number of possible orders in a single moment, and 5 representing (0) action (1) id (2) row (3) column (4) step let's say for example, that server approves a move of the client, it will be like this: (0) 1 = move (1) 32 place is going to move: (2) 4 (3) 5 execute this on this step: (4) 12 problem is, even with this optimization, I mean, I trying to send as least information of a command possible...well the game is still is low, should I suppose that the problem is somewhere else? thanks!! bye!!

excellent, thanks for your advice!

7	Game Development / Networking & Multiplayer / Re: Question on lockstep model on a RTS	on: 2012-12-14 16:40:25
B is the server and A is the client, in this case. the thing is, how does the server knows that the client received the approval? if the client says, "hey, I received the approval, I'm going to move on next turn!" the how does the client know that the server received this? In a short term, If a pack of information is lost, then the game will be desync and I have no way to test that...

Hi! the question is simple. Considering the lockstep model, let's suppose I have user A and B. A wants to move a unit, so it sends the command to B B receives the command and tells A that they will execute the command at step 5 A receives the message the problem is, from the point of view of B, how do B know that A received the message? ok, I can say that A tells B that it received the message succesfully and the will move at step 5...but again....now how do A know that B received this last message? see my point here? I hope I made myself clear. thanks, bye!
