ImportError: No module named Crypto.Random

When I run it it shows me this error:

How to read packet map and get image in jpg

How to make it so that if at the entrance there was a map in hand and read this picture and write it in jpg format

Putting the NBT Exploit in Java

Is there a way to do this in Java?

When I tried to install it, it said the path can't be absolute

This specifically:

Any insight? I'm happy to help in working this out.

Send packets in plugins

Make it possible for plugins to send packets (through PacketSenderManager ?). This would make the plugin system way more useful. As far as I can see, it would only require the socket to be accessible by the plugins.
Also, maybe an overkill, but move chat printing and other game management stuff to plugins ?

[question] 1.7.10?

Is there any way I could make this work with 1.7.10? Did this ever support it? Is there simply something I need to change (I tried recompiling init.pyc with minecraft_version=1.7.10 and protocol_version=437)? Thanks in advance!

Movement

I don't understand how to send the packet to move character

Working version/branch for each protocol version

Hello,

First, I would like to thank you for this wonderful application.

I need to connect to different servers with this client. Unfortunately, those servers are running different versions. It would be nice if you could have different branches or version of your code that would work with the different protocol versions while maintaining the same structure around it.

I wanted to try the version that is compatible with 1.2 but it did not seems to work properly with wx or something. I like the simplistic approach of using the command line you used in the latest version.

This is not an issue. I might try to implement it myself or get a simpler and working version that is compatible with 1.2.

Support for Forge servers with arbitrary mod lists

Is it possible to get support for Forge servers so the client can send arbitrary mod lists to allow connections? Currently when connecting, the server gives the error:

Disconnecting Player: This server requires FML/Forge to be installed. Contact your server admin for more details.

Player Auto Respawn

Can you guys add auto respawn when a player dies?
Thanks

Exploit crashes client, not server

So there is this interesting thing that happens when running the exploit.

The server disconnects the exploit user with:
[00:04:27 INFO]: IJoshFTW lost connection: TranslatableComponent{key='disconnect.genericReason', args=[Internal Exception: io.netty.handler.codec.DecoderException: java.lang.OutOfMemoryError: Java heap space], siblings=[], style=Style{hasParent=false, color=null, bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=null, insertion=null}}

Python gives this:

Exception in thread Networking Thread:
Traceback (most recent call last):
  File "C:\Python27\lib\threading.py", line 810, in __bootstrap_inner
    self.run()
  File "C:\Users\Joshua\Desktop\pyCraft-nbt_exploit\minecraft\networking\connection.py", line 184, in run
    self.connection.file_object)

    length = VarInt.read_socket(self.connection.socket)
  File "C:\Users\Joshua\Desktop\pyCraft-nbt_exploit\minecraft\networking\types.py", line 88, in read_socket
    raise RuntimeError("Socket disconnected")
RuntimeError: Socket disconnected

The server is running with default RAM, I personally have 16 GB.
Is Python somehow running out of memory?

Python version is 2.7.3
Java version is 1.8_40
Server version: Default fresh 1.8.3 running locally

packet 18 and 21 are broken.

line 234 byte = struct.unpack('!b', FileObject.read(1))[0]
line 264 byte = struct.unpack('!b', FileObject.read(1))[0]
line 399 byte = struct.unpack('!b', FileObject.read(1))[0]
line 420 byte = struct.unpack('!b', FileObject.read(1))[0]

those should be an unsigned byte, !B in the PacketListenerManager.py

Does this work on 1.10?

I have spigot 1.10 running and when I try to connect it just says logged in and nothing happens: http://i.imgur.com/CYf4D1U.png

Support 1.7.x

Would be supper helpful to support 1.7.x for existing Modded servers.

Cannot run under Python Tools for Visual Studio

I tried running start.py under Python 2.7 on 32-bit Windows 7, via Python Tools for Visual Studio 2010. I received the following error:

exceptions.ImportError occurred

The exception report is generated in file $/minecraft/__init__.py, line 8 (end of file) The call stack is:

Let me know if I can provide any more info.

Doesn't work in 1.5.*

Literally.

Error on executing exploit payload

Getting this a few seconds after typing "exploit".
The server is running Spigot 1.8 (implementing API 1.8-R0.1) with bungeecord (however I dunno if that matters).

Invalid NBT data in nbt_exploit

I believe the data used for the exploit (in the nbt_exploit branch) is an invalid NBT:
The write_lists function recursively calls itself, but before the last recursion it writes "list of 10 items" into the datastream, but then fails to write any data for those 10 items in the last recursion.

Authentication times out during Travis tests.

See for example this job: https://travis-ci.org/ammaraskar/pyCraft/jobs/217173485, with relevant output below:

-------------------- >> begin captured logging << --------------------
requests.packages.urllib3.connectionpool: DEBUG: Starting new HTTPS connection (1): authserver.mojang.com
--------------------- >> end captured logging << ---------------------

These timeouts seem to be due to high network load when multiple tests are run in parallel, and happen infrequently and nondeterministically.

One solution might be to increase the timeout, but I'm not sure if this is satisfactory, as this is only a problem in the testing environment. An alternative solution could be to reduce the number of Travis tests that are run in parallel.

EOFError on connect()

I have the following worker function:

    token = authentication.AuthenticationToken()
    token.authenticate(*account)
    print "Logged in as {0}:{1}".format(*account)

    packet.message = "test"
    connection.write_packet(packet)
    time.sleep(1)
    connection.disconnect()

Upon calling this from an interpreter:
worker(("email", "password"), "server", port)
I am able to login, but upon attempting connection, I receive this error:

Add a option to dont try to authenticate to mojang server (Offline)

I've seen that the bots branch has a option to use offline mode, It would be great to have it in the master branch, so I only need to put a username and a address to connect to it

Any chance they can either be converted to colors or just parsed out?

Color coded Chat (instead of JSON) with ANSI Color?

Hi,
I just wanted to check-in if a color coded chat would be something that would fit this scope of this project?
Technically its pretty much at the border of being a python library to provide access to minecraft servers but on the other side there are python classes available that also be used as real client and thus I think it might be worth double checking.
Maybe it would be something a user enables/disables with a switch (so just a side library that would allow to convert the JSON-Text to something colorfull.

Just a side-note:
This might only work on windows 10 most likely out of the box, since it got added to windows 10

Let me know...

High memory usage on server after ~12 hours

Description

After ~ 12 hours with a pycraft account connected to a server (1.12.1), memory usage on server is way more higher than official client or Minecraft Console Client (more than 2×): on my Ubuntu server with 16GB RAM, using htop, official client consumes 2.2%, MCC (Minecraft Console Client) consumes 3.0% and Pycraft consumes 7.1%. This seems to happen too with 1.11.2 server.

I'm using the latest version 46e058d, zip-downloaded from GitHub. But I was able to reproduce with an older version, before 1.12.

Steps to reproduce

On a server, create a specific folder for Minecraft Server.
Download official server jar from Mojang: https://minecraft.net/fr-fr/download/server
Start a first time the server to generate eula.txt file.
Accept EULA.
Start again server, then run commands "difficulty 0" and "gamerule doMobSpawning false" to prevent mob generation (and random ram consumption).
Stop server.
(Optionnal) in server.properties, set online-mode to false to make tests easier.
Copy Minecraft Server folder twice: one for Pycraft client, one for MCC, one for official as reference.
In each directory, set a different listening port, and rename jar to readable name (for example, "minecraft_server.1.12.1_pycraft.jar")
Start each server
Connect at the same time one pycraft client, one MCC and one official client to its corresponding server.
Wait ~12 hours
Using any system tool, check memory usage for server: pycraft should use way more RAM than the others.

Expected results

Pycraft server should use almost the same quantity of ram than the other clients.

AuthenticationToken.validate will never work as Mojang returns a 204.

Here is where pyCraft checks for the code 200 (ok) but the validate response returns 204 if successful thus AuthenticationToken.validate will never work

Using a Proxy

hello, wondered how to connect a bot with a SOCKS5 proxy

Cannot seem to write location packet

Hello,

I am receiving the following stack trace. I am attempting to have the client moves when it receives a certain chat string, and am attempting to write the packet from the packet_listener function call. Any advice.example on how to properly do this?:

    connection.register_packet_listener(process_location_data, PlayerPositionAndLookPacket)
    def print_chat(chat_packet):
            for chatline in chat_payload.get('extra'):
                concatted_chat += chatline.get("text")
                
            if "!magicstring" in concatted_chat: 
                #current_position = PlayerPositionAndLookPacket
            
                packet = PlayerPositionAndLookPacket()
                packet.PositionAndLook(x=-7400, y=1, z=5319, yaw=160, pitch=160, teleport_id=1, flags=0b11111)

                packet.x = 1.0
                packet.z = 1.0
                packet.y = 1.0

                packet.yaw = 150
                packet.pitch = 150
                
                packet.teleport_id = 1
                
                # Now a relative move
                packet.flags = 0b11111

                #packet.apply(current_position)
                connection.write_packet(packet)
                
                print('position change trigger')

Do you plan to update this for minecraft 1.7 support? I need it and I'm sure others do too. Thank you for the program, by the way. It's impressive!

I was wondering if you could possibly make the Command-Line interface work if wxwidget is not installed. It should only be a matter of try/catch, shouldn't it ?
