OGE (Orbital Game Environment)

OGE is a reinforcement learning environment for orbital game scenarios, focusing on spacecraft pursuit-evasion games. The environment provides a Gymnasium-compatible interface with a high-performance C++ backend and Python bindings for easy integration with mainstream reinforcement learning frameworks (such as SKRL).

Features

• 🚀 High-performance orbital dynamics simulation (C++ backend)
• 🎮 Gymnasium-compatible reinforcement learning environment interface
• 🤖 Multi-agent pursuit-evasion game scenarios
• 📊 Integration with SKRL reinforcement learning library, supporting PPO and other algorithms
• 🔧 Flexible environment configuration system

1. Development Environment Setup

1.1 Update GCC

Install GCC 13

sudo apt update
sudo apt install build-essential gcc-13 g++-13

Set as default version

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-13 100
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-13 100

If you have multiple versions installed, you can switch between them:

sudo update-alternatives --config gcc
sudo update-alternatives --config g++

Verify the installation:

gcc --version
g++ --version

Expected output:

(oge) ➜  OGE git:(main) ✗ gcc --version

1.2 Install vcpkg

Clone vcpkg and run the installation script

git clone https://www.github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.sh

Add the following to your ~/.bashrc or ~/.zshrc

# >>> vcpkg
export VCPKG_ROOT=<path-to-vcpkg>
export PATH=$VCPKG_ROOT:$PATH
# <<< vcpkg

1.3 Python Environment Setup

Create a conda environment and install dependencies

conda create -n oge python=3.13
conda activate oge
pip install -r requirements.txt

Install the skrl library

conda activate oge
pip install "skrl[torch]==1.4.3"

2. Install OGE

conda activate oge
pip install .

3. Run SKRL Training Example

python scripts/train.py
