Hi,

(sry bad english !)

Please i need HELP or a fix !! to get the right GnetMessageObject from a GnetMessage.

I wrote a litle Samplecode, i need GnetMessages and i got no time to write a new "lowlevel- NetLib" like Gnet for me, and Gnet allready exist and it works fine but this one problem is a Great Problem and it makes Gnet bad.

I try the Fix
http://blitzbasic.com/Community/posts.php?topic=80476

but it doesn't work

Try This code and start more Instances, every GnetObject send a Message (all 2000 Millisecs), in a normal case each Client must receive a
remote message and do print a ID string but nothing like this "Sender Is LocalClient" is happens.

Hi,

GNetMessageObject returns the object the message was sent *TO*, which will always be a local object as far as the receiver is concerned.

There is no *from* mechanism to identify the sending object - you can implement this is you want using SetGNetXYZ on the message before sending it.

I suspect you are not using GNet the way it was designed - the message objects are meant to contain simple message like 'begin game', 'abort game' etc commands sent from the game server to all game objects.

For a more pure messaging API, try eNet.

Ok thx for your Awnser.

I do use Messages for Shoot's, i think messages have a greater chance to be received 100% from clients.

I handle Logins and Logouts with another solution. Each GnetObject become a Target if not Target exist the Object must be a new (a Login) Object and then it will be bind as a GameClient, Position etc. are transmitted with GnetSETXYZ and it works fine but when i use it for realy importent Messages like Shoots it doesn't work 100% also i think Messages are a the better way to send shoots btw. to send realy importent Messages.

But GnetMessages don't send a Referenz from where it come and in this case a Gnet User must write a SessionID system, then a Message do send a simple ID wich will be Identifikated a Client who have send a Message.

And now the a big WHY !

Why Messages don't send the GnetHost or the GnetObject from where it come. it can makes many things easier. In fact, a MessageObject is a standard GnetObject so i think IT MUST SEND a *from* ! :) !!

It doesn't exist a good Manuell for GNET only some Codes i can find to learn Gnet. In the process where i learn'd Gnet, i find it very good but this one stupid thing makes that i now write my on NetLib (i think time is Importent but running Code does have more Priority.) it's not a problem but the time :( , ok it's not hard work to Implement a ID system but it exist one and it identifikats Objects but not Messages this is not a good way and another problem is the UserManuell that doesn't exist for GNET then to know how work with Gnet you must know how work Gnet !

( i hope you can understand what i have write )

(if you want take a look how does it works atm. try this

http://www.c64.feuerware.com/new_hc/downloads/HC_nettest.rar

, change the Resolution to 500x500x32x2 (first 4 lines in settings)and start 2 Instances (ip and resolution can set in Settings.set , it runs very fine but now i must rewrite the NetLib )

bye C64.

I also have to say I think this would be a great feature. Why not give the ability to do such a thing in every way possible?
