LunarLander:

A simulation environment for lunar lander using SFML, Box-2D in C++ using Reinforcement Learning. The scripts under Experiments can be used to check the creation of the custom environment. Main.cpp is the full implementation of the training of Lunar Lander simulation in C++

Instructions for Running main.cpp

This repository contains a shell script and C++ source file to compile the main.cpp file using g++ and required libraries.

Prerequisites:

Ensure you have the following installed:

g++ compiler: To compile the C++ source code. SFML: Simple and Fast Multimedia Library. Box2D: A 2D physics engine. LibTorch: PyTorch's C++ library.

Instructions:

Follow these steps to compile and run the C++ code using the provided shell script:

1. Clone the repository:

   git clone https://github.com/adithya2424/LunarLander.git

2. Navigate to the directory:

   cd LunarLander

3. Make the shell script executable:

   chmod +x compile_torch.sh

4. Run the shell script:

   ./compile_torch.sh

Script Details

The shell script compile_torch.sh includes the compilation commands using g++ along with required library paths and flags to compile main.cpp and create the executable output.

#! /bin/sh
g++ -g -std=c++17 main.cpp -o main \
    -I include \
    -I/Lunar_Lander/libtorch/include \
    -I/Lunar_Lander/libtorch/include/torch/csrc/api/include \
    -D_GLIBCXX_USE_CXX11_ABI=0 \
    -L lib \
    -L/Lunar_Lander/libtorch/lib/ \
    -lsfml-system -lsfml-window -lsfml-graphics -lsfml-audio -lsfml-network -lbox2d -ltorch -lc10 -ltorch_cpu \
    -Wl,-rpath ./lib \
    -o output

Please ensure that the paths mentioned in the script (/Lunar_Lander/libtorch/include, /Lunar_Lander/libtorch/lib/, etc.) match the actual paths on your system.

The Lander has below safety monitors:

1. Reset the System Upon Crossing the window border either Up, left, Right.

   Visualization for Move Up Action:

   

   Visualization for Move Left Action:

   

   Visualization for Move Right Action:

   

2. Collision detection down when there is a contact between terrain and the Lander
