copied!<p>We are working on an RTS game using XNA, and I've been tasked with the networking (well, we kind of finished the game, and I recently picked it back up). To cut to the chase, I have had a ton of issues with sockets, missing packets mostly for a lot of different reasons, but I think I've solved most of them. (We're using TCP even ..)</p> <p>To try to solve issues, I've created a network tester, which will send packets to the server, which will send them back, after which I can see if there were dropped packets etc.</p> <p>One of my tests is a 'deform' test. Basically I grab the random function, generate a number, convert it to an MD5 String, and send it to the server. When I receive it back, I compare it to the strings already sent, and see if there was any corruption (comparison <em>should</em> be 100%, as in, all sent strings were found in the received list).</p> <p>Now, here's a snapshot of the results:</p> <p>Sent: </p> <pre><code> [0] "69-AB-DA-CC-1A-66-6A-27-C5-B4-FF-B7-2D-9F-75-06" string [1] "1C-16-68-98-DF-6C-C9-16-54-5A-94-00-CA-57-77-CC" string [2] "B6-24-7E-79-0C-66-14-5B-C0-32-F5-17-06-5D-13-87" string [3] "1E-99-DE-1F-25-30-6E-DF-59-0D-05-2B-43-8F-07-16" string [4] "76-82-30-13-C2-B4-33-7D-32-E2-04-C7-13-3C-F3-AB" string [5] "23-BF-A2-F4-E4-77-78-6B-A5-2C-D2-6B-6F-B3-6F-44" string </code></pre> <p>Received:</p> <pre><code> [0] "&\0\069-AB-DA-CC-1A-66-6A-27-C5-B4-FF-B7-2D-9F-75-06" string [1] "&\0\01C-16-68-98-DF-6C-C9-16-54-5A-94-00-CA-57-77-CC" string [2] "B6-24-7E-79-0C-66-14-5B-C0-32-F5-17-06-5D-13-87" string [3] "1E-99-DE-1F-25-30-6E-DF-59-0D-05-2B-43-8F-07-16" string [4] "76-82-30-13-C2-B4-33-7D-32-E2-04-C7-13-3C-F3-AB" string [5] "23-BF-A2-F4-E4-77-78-6B-A5-2C-D2-6B-6F-B3-6F-44" string </code></pre> <p>I'm getting roughly 50% packets correct. I could post the socket code and such, but I dare say it's rather complex. Still, if it's needed, I'll post it. Is there some socket-related thing I'm missing? I am hoping for a quick fix .. but I doubt there will be any seeing previous problems we had.</p> <p>Thank you in advance for any suggestions.</p> <p>Edit: View the github repository here: <a href="https://github.com/Wotuu/RTS_XNA_v2/tree/master/SocketLibrary" rel="nofollow">https://github.com/Wotuu/RTS_XNA_v2/tree/master/SocketLibrary</a></p> <p>By request, some code snapshots: MD5 creation: <a href="https://github.com/Wotuu/RTS_XNA_v2/blob/master/PathfindingTest/PathfindingTest/UI/Menus/Multiplayer/TestConnectionMenu.cs" rel="nofollow">https://github.com/Wotuu/RTS_XNA_v2/blob/master/PathfindingTest/PathfindingTest/UI/Menus/Multiplayer/TestConnectionMenu.cs</a> :222</p> <p>String->byte: <a href="https://github.com/Wotuu/RTS_XNA_v2/blob/master/SocketLibrary/Packets/Packet.cs" rel="nofollow">https://github.com/Wotuu/RTS_XNA_v2/blob/master/SocketLibrary/Packets/Packet.cs</a> :113</p> <p>byte->String: <a href="https://github.com/Wotuu/RTS_XNA_v2/blob/master/SocketLibrary/Packets/PacketUtil.cs" rel="nofollow">https://github.com/Wotuu/RTS_XNA_v2/blob/master/SocketLibrary/Packets/PacketUtil.cs</a></p>
