PyCraft - A Minecraft launcher made in python

Overview

PyCraft

A Minecraft launcher made in python. The main objective of this launcher is to enable players to enjoy minecraft (especially those without a mojang/microsoft account). This launcher is not illegal as all files are downloaded from libraries.minecraft.net

Features

This launcher is based on the Tkinter and minecraft_launcher_lib. It offers mojang login and cracked login.

Includes a special FPS boost option.

Includes an in-built toggleable vpn, running through torsocks(Linux)

To run Tor on windows as a service : https://deepdarkweb.github.io/how-to-install-tor-on-windows-without-the-tor-browser-running-tutorial/

Fps boost has been shifted to experimental mode. That is , it has 50-50 chances of working successfully.It is still under development. Feedback would be most graciously appreciated.

Discord Rich Presence (Rpc) added.

Installation

Run python install.py or python3 install.py(if on linux)

Then run python pycraft_gui.py or python3 pycraft_gui.py

Before starting minecraft, do increase or decrease the ram in the settings, so as to update it in the settings file. Or else an error will pop concerning the JVM.

I will patch this in future releases.

IMPORTANT

After stopping a download, please press CTRL+C twice. (This will close the launcher as well.) For people who have worked with python, it's an issue where i am unable to close the download thread directly at once by raising the KeyboardInterrupt exception.

If download fails, you may need to use a vpn(windows) or enable tor in settings(linux)

A recent bug has been fixed in minecraft forge(modded minecraft) installation. If on linux just replace the forge.py file in the patches folder with the on in either /usr/lib/python3/dist-packages(if allowed, coz most installations are not done here without sudo) or /home/(your username)/.local/lib/python3/site-packages/minecraft_launcher_lib/forge.py.

On windows replace at C:\users\yourname\Appdata\local\programs\python(version-number)\site-packages\minecraft_launcher_lib\forge.py

Ignore the upper two messages if installing for the first time. Still if error pops up you can apply the fixes as mentioned.

Any changes in the settings (be it tor, fps boost, ram change, directory change) will require a launcher reboot(not to be confused with system reboot), to take effect.

Why the whole vpn thingy?

Sometimes mojang's server, libraries.minecraft.net is not available on some systems (especially for those living in Egypt). To fix this a vpn is used. Now the governement of Egypt has kinda cracked down on openvpn (thanks to one of my testers, i wouldn't have known about it otherwise.), so Tor is the best solution to that.

Coming soon:

FunMc (my minecraft server's website) and it's API for skin systems and capes (absolutely free)

New microsoft account login system as per the latest changes according to mojang in Minecraft: Java Edition

    Hi there! I saw you made a lot of changes and also added some information regarding nsis stuff to build an installer. And I made made some changes to main.py fixing annoying GUI issues. I think we should merge our branches.

  • JDK Installation Failing

    JDK Installation Failing

    Hi!

    This is my first time writing something like this, so please do bear with me (I'm a newbie in Python, so I'm not 100% correct, nor am I confident on this, but I raised it to verify if it is possible - I'll be doing it a bit later). I posted this just in case there are others who would encounter the same error as I did.

    Screenshot (251)

    As per the screenshot, it shows that the installation package cannot be opened. It says that either: (a) The package does not exist, or (b) it isn't a valid Windows installer package. Instead, I snooped on install.py, and I found that you specifically used Liberica JDK 17.0.3 (via the download link given) for this project. However, checking the developer's site, I found this which states that:

    Some users running on Windows may encounter Windows Defender SmartScreen popup during installation of Liberica JDK: This is caused by a new certificate used by BellSoft to sign the binaries.

    Their recommendation is to run it anyway (it gets flagged by Windows Defender Smartscreen Popup, so Situation B is likely the case). Knowing this, there are two possible options: (a) Install the specific JDK version manually (but I'm not sure how this would work, because the code doesn't seem to check if that specific kit is already installed), or (b) as the developer's link says, run a silent installation by adding /quiet to the installation configuration at line 54, as shown below:

    pycraft diagnosis-proposed_modification

    I haven't really tested any of the two yet, but I'm going to do the latter. I'm hoping it might work. Cheers!

    Also to note: I ran this with Python 3.9.12. I tried running it first on 3.10, but it fails because of a problem with the wget() function. Seems like the function isn't working properly on 3.10, based on what I saw after I tried installing a package (I don't remember if it was PIP or not: I'm a newbie, so I didn't completely understand what it statement was when I initially saw it - I only remembered when I tried running this).

    Opening the launcher, selected version 1.8.9, and tried to launch the game. The launcher started to download the JRE. This download is very slow (so far it's been around 2 hours), and has high CPU usage (around 50%). Actual network usage is low. It seems to be downloading about 1 file per minute. image image
