How to get a channel list

[inewland53]

I was running into a read error when trying to get the Player Limit as well. In order to get a ushort from the BinaryReader you need to use this code:

1. int playerLimit         = reader.ReadUInt16();   // Don't use ReadInt32();
2.  

Hope that helps someone.

1. void OnChannelList(Packet response, BinaryReader reader, IPEndPoint source)
2.     {
3.         Console.AddMessage("Fetching Room List...");
4.  
5.         int count = reader.ReadInt32();
6.  
7.         for (int i = 0; i < count; ++i)
8.         {
9.             int channelID = reader.ReadInt32();
10.             int playerCount = reader.ReadInt32();
11.             bool password = reader.ReadBoolean();
12.             bool isPersistent = reader.ReadBoolean();
13.             string level = reader.ReadString();
14.             string channelName = reader.ReadString();
15.  
16.             print(playerCount);
17.         }
18.  
19.         Console.AddMessage("Fetched Room List");
20.     }

From this code you can see that I should get a message in my Unity console containing the number of players in a channel.
For some reason I get rediculous 6 digit numbers instead of the amount of players in a channel.

Example: 1 player connected to a room is supposed to print "1". Instead I get this: "589825"

Please help

you are reading an "int" when it should be "ushort"...

this problem was addressed many times on page 1 of this thread.

1. /// <summary>
2. /// List open channels on the server.
3. /// int32: number of channels to follow
4. /// For each channel:
5. ///   int32: ID
6. ///   ushort: Number of players
7. ///   ushort: Player limit
8. ///   bool: Has a password
9. ///   bool: Is persistent
10. ///   string: Level
11. ///   string: Custom data
12. /// </summary>

Thanks! This seems to have solved my problem

However now I just want to know. What is the difference between, int, int16, int32, int64, uint16, uin32 and uint64..

The difference is size in bytes. Int16 is 16 bits (2 bytes). Int32 is 32 bits (4 bytes) and Int64 is 64 bits (8 bytes).

You were trying to read too much data from the stream.
