<div>Wow, thanks for the fast reply.</div>
<div> </div>
<div>You cleared up quite a bit of my confusion, too.</div>
<div> </div>
<div>I ditched my vector of peer pointers, and am now using the host->peers instead.</div>
<div>Also, instead of using a dummy connection when I want to play on non-dedicated server, I do something like this:</div>
<div> </div>
<div>maxPlayers = 12;</div>
<div>if(!dedicated) maxPlayers--;</div>
<div>host = enet_host_create(&address, maxPlayers, 0, 0);</div>
<div>serverPlayer = maxPlayers;</div>
<div> </div>
<div>this will only allow for 11 other players to join. And they will fill spots 0 to 10 in the host->peers array.</div>
<div>The player the server now controls is player[serverPlayer] - which is the 12th and final player. So I don't have to worry about it being replaced, etc..</div>
<div> </div>
<div>Hooray, first 4 questions solved!</div>
<div> </div>
<div>As far as question 5 goes, I'm now using ENET_HOST_ANY. Regarding LAN.. what should I do then? Keep it as ENET_HOST_ANY? I read somewhere that the client should then set it's address to ENET_HOST_BROADCAST, and that will return any server addresses? I tried, but it didn't work.. Do I have to connect twice or something? Once to find the address, and then again to connect to it?</div>
<div> </div>
<div>Also, can a server host for both LAN and the internet at the same time? So anyone can join, whether they're in the LAN or on the net? If not, for testing purposes, is it possible for me to use my second computer which is on the LAN, but get it to join via the internet, so I can check to see if I've got both the LAN connection and the internet connections working properly. I've been reading a lot about NAT punch-through, so I imagine I might have to deal with that in the future, as I am using a router.. but hopefully I can get at least LAN working first.</div>
<div> </div>
<div>Thanks again!</div>
<div>Ben.</div>

Content-Type: text/plain; charset="iso-8859-1"<br><br>Hey all, first post!<br><br>I was looking around and Enet appears to be what I'm after. I'm making a<br>game using a server/client model, but there are a few things I'm unsure<br>
about.<br><br>What is the best way to manage peers from the server end? So I can store<br>peers, and associate them with a particular player. Basically, when a player<br>joins the server, I'd like the server to add this peer to a list, and assign<br>
it an ID so I can link it with a player. Then, when they disconnect, I'd<br>like them to be taken off the list.<br><br>At first I tried making: std::vector<ENetPeer*> peers;<br><br>and each time a player joins, scanning through this vector, checking:<br>
if(peers[i] == NULL) peers[i] = event.peer;<br><br>thus replacing that peer. Then, when a peer disconnects, looping through<br>this vector, checking:<br>if(peers[i]->address.host == event.peer->address.host &&<br>
peers[i]->address.port == event.peer->address.port) peers[i] = NULL;<br><br>Then, the way I associate each peer with it's corresponding player object is<br>simply that they both share the same index in their respective vectors. So<br>
player[7] would belong to peers[7].<br><br>ANNYWAY.. this doesn't seem to be the best method. Because some people in<br>the archives have mentioned that the host actually has it's own list of<br>peers. And that it does all this for you? And that when a new peer connects,<br>
you can get the index of the new peer like:<br><br>case ENET_EVENT_TYPE_CONNECT:<br>int index = (int)(event.peer - host->peers);<br>...<br><br>So my questions are (there's a lot, I know.. sorry):<br><br>1) is my original way a good way? Or should I use host->peers instead?<br>
2) If I use host->peers.. will the host also manage the deleting of peers<br>when it gets a disconnect? If it does, does it rearrange the array? So if I<br>have 3 peersconnected, and then the 2nd one leaves.. will I still be able to<br>
access the third player with host->peers[2] or will it get dropped down to<br>the 2nd position at host->peers[1]? Furthermore, would it be best to save<br>the playerID into the data field?<br><br>3) Is the array size of host->peers set by the 2nd parameter in<br>
enet_host_create? So if I put in 64, will that mean 64 clients can be<br>connected at once?<br><br>4) I want my game to have a dedicated and a non-dedicated server option. If<br>it's non-dedicated, then you will control player[0]. Thus it would be<br>
convenient if I could also block off host->peers[0] (or my original<br>peers[0]) with a 'dummy' connection to itself. Is this possible? Is it wise?<br>Like, upon creating the host, could I go:<br><br>if(!dedicated) host->peers[0] = enet_host_connect(host,&address,2);<br>
<br>5) LAN vs Internet vs same computer. At the moment, all I'm able to do is<br>get 2 applications on the same computer connecting. Is this because I'm<br>using enet_address_set_host(&address, "<a href="http://127.0.0.1/" target="_blank">127.0.0.1</a>") when creating the server?<br>
If I wanted the server to be recognisable on LAN what address would I use?<br>How about the net? or both at the same time? Would I just use address.host =<br>ENET_HOST_ANY? If so, how do I know which IP to search for on the clients<br>
end?<br><br>Ok.. that's all for now. If you can answer any questions at all, that'd be<br>great :)<br><br>Loving Enet so far, hopefully I can get past these basic concepts and get<br>into it more!<br><br>Thanks,<br>

<br>There is a "void *data;" field in ENetPeer which ENet never touches, so<br>you can set it to whatever you want, i.e. it can point back to your<br>player structure.<br><br>The internal array of peers is fixed size and never reordered. When a<br>
client comes in the first available entry is used for the new<br>connection, but otherwise the same entry is always used for the duration<br>of the connection.<br><br>Yes, what you pass in to enet_host_create is the maximum number of peers<br>
it can support.<br><br>You can't assign an index in the peers array like you suggest. Just<br>don't do it. However, the first connection issued by enet_host_connect,<br>so long as no other connections have been created, is almost guaranteed<br>
to be put at peers[0].<br><br>If you want the server to be recognizable, don't use localhost as<br>address.host, it must either be an IP address that is guaranteed<br>recognizable from outside, or ENET_HOST_ANY to just take whatever IP the<br>
OS assigns, whichever. You must still give it a fixed port number, however.<br><br>Lee<br><br>Ben Johnson wrote:<br>> Hey all, first post!<br>><br>> I was looking around and Enet appears to be what I'm after. I'm making<br>
