Rollback Engine

A "Linux-First"¹ Game Engine

• Includes modern features like SDL3 and Vulkan
• Ability to Cross-Compile for Windows by default
  • Maybe other platforms in the future
• Aims to bring convenience to Game Development for Linux without sacrificing access to other platforms

Requirements

The repository's boostrapper will set up your environment for you. There will be some things you need pre-installed on Windows environments. Linux Environment MUST BE Ubuntu 24.04 LTS at the time of writing.

Windows

1. Visual Stuido Code
   • VS Code will be the editor we use to connect to our Linux environment
2. Windows Subsystem for Linux (WSL)

Quick Start Guide (Source Compile)

Linux

First, clone the Repository:

git clone https://github.com/John-Ridgway/RollbackEngine.git

Navigate to the setup directory:

cd RollbackEngine/setup

Run the Bootstrapper*:

./run-bootstrap.sh

*you will need root privilege for this

---

VS Code tasks have been included with this repository. To compile in VS Code for both Linux and Windows, follow these steps:

CTRL+SHIFT+P -> Run Task -> Build All

If you aren't using VS Code, in your terminal from the Project root (e.g. /RollbackEngine) run the following commands:

Linux

cmake -S . -B build
cmake --build build -j

Windows

cmake -S . -B build-win -DCMAKE_TOOLCHAIN_FILE=./toolchains/toolchain-windows.cmake
cmake --build build-win -j
cp ./deps/sdl/win/bin/SDL3.dll ./build-win

*For windows we need to copy the SDL3 dll

Run the Application

Linux

./build/RollbackEngine

Windows ²

sudo apt-get install wine -y
wine ./build-win/RollbackEngine.exe

Summary

Nothing fancy for now. A simple window initialization for testing that the libraries are compiling correctly.

Footnotes

1. This application is being developed in WSL2 (Ubuntu 24.04 LTS) for now. ↩

2. wine is not included as a necessary dependency in the bootstrapper. If you wish to test Windows compiles without leaving your Linux environment, you will need to add it. ↩
