A updated version of SkyblockSniper by csjh
Download Python 3.7.8. There's literally thousands of guides on how to do this so I'll assume you can figure it out yourself.
Either download this repository or just copy paste all the code from inside SkyblockSniper.py into a new file on your computer called SkyblockSniper.py, and all the text from requirements.txt into a new file on your computer called requirements.txt.
Run the command pip install -r <path to requirements.txt> in the command prompt (Window key + R, type cmd). For example, on my computer, the path to requirements.txt is C:\Downloads\requirements.txt, so I'd use pip install -r C:\Downloads\requirements.txt.
Run the file SkyblockSniper.py by going into command prompt and running the command python <path to SkyblockSniper.py>. For example, on my computer, the path to SkyblockSniper.py is C:\Downloads\SkyblockSniper.py, so I'd use python C:\Downloads\SkyblockSniper.py.
Now the script is running good and well. From here, you can just AFK on your island splitscreened watching Netflix or something. As soon as the script finds a good flip, you'll hear a low frequency beep for half a second, and the command to go to the auction is automatically put on your clipboard.
All you have to do is Ctrl+V every time you hear the beep, make sure it's not a scam (sometimes this happens with cosmetics or other market manipulation; can be prevented with NEU's average AH price thing), and then buy it.
