*Bump*

Ankron · 08-01-2015 03:54 AM

I've got a project on hold because I can't compress the packets right, and the code I have for compression isn't working. I'm thinking that I could build a client helper program of sorts but unless I can compress packets, the project is sunk. Does anyone know why this code I pasted isn't working right?

Is anybody out there?

Ankron, i installed a huffman class on the code, can we talk tonight?

I passes trought server connection, but the client list seems not to be working....

See yah

Note: i spent a lot time understanring how the server "cache" the packrta to send/receive

Now the code is almost running on standalone php server (linux, mac and windows) Big Grin

Ankron, i think i made the compression...

Code:

Just need to send a string of chr() to the function, and it will return a string of chr() compressed Smile

OBS: The server is allready running on a standalone version...

I've created this repository to keep creating the standalone version: https://github.com/joaoescribano/UltimaPHP

With this, you can run the server from any PHP 5.3> installation (linux, mac and even windows).

Ultima One · 08-13-2015 12:08 AM

Looking good, can't wait to try it out guys

escribano · 08-13-2015 02:49 AM

Ultima One, you'r more then wellcome to work with me and Ankron!
We will need all help from everyone who want to improve the server!

Just fork the code from my git repository, and change-it as you wish!
If you need help in something, me and Ankron are here to help!

See yah!

Ankron · 08-14-2015 03:29 AM

Still not working right on the compression, not really sure why. I'll put to gether a new package for you to look at. Got the Github info?

escribano · 08-14-2015 03:49 AM

Ankron.. i see that the compression didn't work propertly Sad

and i really don't understand why...

I'm trying now to convert the packet to binary (to the method receive and array of bytes (8 zeros or ones) in each key) and see what in the hell happens!

Tongue

we talk later!

escribano · 08-14-2015 06:18 AM

Ankron.. i guess we coul use the GZDeflate OR GZCompress method.

POL uses deflate to compress the packets with no predefined tree... "maybe" this is the solution... i dunno now but I'll try tonight! see yah
