Satisfactory External "Bhop" Cheat

While exploring my Satisfactory savefile, I noticed an interesting movement bug. If you sprint, walk forward, and then slide for a second, your character will slide and then, after ~500 ms, repeatedly pressing the jump button while still holding the first three inputs allows you to move approximately 5x faster.

I decided to automate this behavior using a fully configurable C++ application. The program waits for you to hold the walk-forward and sprint keys, then automatically performs the slide and repeated jump actions, effectively "bhopping" without manual input.

Note

This project is for educational purposes only. While it simulates a movement exploit, the focus is learning Windows API, input simulation, config management, and C++ development. It has been a challenging project because I was only familiar with arrays when I started, but I completed it.

What I learned

• Reading and parsing configuration files in C++
• Simulating keyboard input using Windows API (SendInput)
• Using std::this_thread::sleep_for to manage timing and CPU load
• Structs and maps for clean, modular code
• Continuous input monitoring with GetAsyncKeyState

Features

• Configurable keys for Walk Forward, Sprint, Crouch, and Jump
• Configurable delays:
  • Delay before crouch
  • Delay before jump spam
  • Interval between jump presses
• Works both in Notepad for testing and in Satisfactory
• Uses Windows API SendInput to simulate key presses
• Minimal CPU usage (via std::this_thread::sleep_for)

Setup

1. Clone the repository:

git clone https://github.com/michal-flaska/satisfactory-external-bhop-cheat.git

2. Open the project in Visual Studio.
3. Ensure config.ini is set to Copy to Output Directory in the project settings.
4. Build the project in Release mode.
5. Run the generated .exe while Satisfactory is running.

Configuration

edit the config.ini file.

Hex codes must follow Windows Virtual-Key codes. You can find the list here: Virtual-Key Codes

Usage

1. Launch the executable.
2. Press and hold Walk Forward + Sprint.
3. The cheat will automatically handle crouching and jumping based on your config.
4. Release Walk Forward or Sprint to stop.
