Building

Prerequisites

To build this project, you will need:

  1. clang or a compiler with C++23 support (eg. clang)
  2. cmake version 3.26 and above
  3. ninja (or any other cmake supported build system)

Instructions

The following instructions will assume you are using ninja as your build system

  1. First install ninja. See here for instructions

  2. Secondly clone this repository and its submodules:

git clone https://github.com/ultraflame4/GravSim.git --recursive --depth=1
  1. Use cmake to generate project build files.
cmake -S . -B build -G Ninja
  1. Build the project with.
cmake --build build
  1. Run the executable GravSim.exe in the build folder

Notes:

  1. The collision physics is very buggy.

2. Spawning too many bodies will make them disappear. I have no idea why. fixed
