There have ben a war that some ones claims tcp in blitz basic is useles for gamming. this code is prof of oposite. This code is the Core thinking of my new Tiberion engine. Please fell free to expand it to somthing usefull. I have tryed to make it so smal and easy to understand as possible. | |||||

the only thing that bothers me is that if tiberion.com, whatever that is, goes down, all porgrams based on this wont work anymore... |

@Devils Child I think you can just change : link=OpenTCPStream("www.tiberion.com",7056) to your own ip address. Eg:link=OpenTCPStream("127.0.0.1",7056) I tried this and was able to run both client and server on the same machine |

sure. but isnt there running a php script within the server which manages the TCP connections? i bet there is. |

nope, he is using server and client which he both posted above ... not some kind of meta server to talk to each other. Makes sense as it seems to be targeted to be the networking of an online gaming technology, not a matchmaking tech :) Thank you for providing this :) Surely interesting, the main problem I see with it is that the receive buffer is restricted to a single message. Does that work "usefully" when the server receives multiple messages from that user within the given timeframe? I mean towards the consistency of the data between players if you only process a single message of a player during one go, instead of all messages from that player for each player within that tick. |

Thankyou for this code, it works great, I did one extra change to get it working in Blitz3D on top of Destroyer's suggestion:- relpaced:- ;window=CreateWindow("Key press me window",100,100,640,200,0,1) with Graphics 800,600,16,2 Thanks again! |

@Wings, I've expanded your code a little and am very impressed with it's speed. Fresh post lower down, hope you don't mind me adding to your code. I'd to stick a hefty delay of half a second in too slow it down enough - like you say - it's ultrafast!...but if anyone wants to see the expanded code I'll post it.... The first two bytes from each packet for the client to send how many packets it had sent, and used the second byte for the Server to let the client know how many clients the server reckoned were connected. Since the version that is on here I have implemented a system whereby each new client will result in the server writing a new file to a directory containing details of each new client, with 512 bytes per packet there's plenty storage. |

for sure..... post it. |

Have moved it forward a little more now, It now writes a unique file name to a sub directory that you need to create in the same directory as server_v2 and client_v2 executables, called file_dir. This sub directory is used by the server to maintain a list of the clients that are running. I have developed a VB.net front end for the two executables server_v2 and client_v2 that keeps a running count of the clients running, will kill the server and subsequently clean up the file_dir sub directory of historic client files. You do not want to put any of your own files within the file_dir directory, this directory gets cleaned very well upon Kill Server! Link to VB.net front end: http://myweb.tiscali.co.uk/diecastcars/File_Counter.exe NOTE: Do Not try to run the File_Counter.exe file before you have created a subdirectory call file_dir at the same path. Nothing BAAaaad will happen, it just wont work (;-) So: You might want to put your server_v2.exe and client_v2.exe at the same path as File_Counter.exe, else the start server and client buttons won't find what they need. Image removed Server: Client: Hope this helps someone..... |

Posted new version of the code here, client requests x and y co-ordinate movement now to the server. See here: http://www.blitzbasic.com/Community/posts.php?topic=76772 Many thanks to Wings for posting his excellent code that enabled me to get so far...... |
