tsEngine

This project is a small and simple 2D game engine I am building from scratch to learn about how modern engines (and games) are made. Written in C++17. My knowledge of 3D graphics is basic at the moment, so I ended up using SDL2 for rendering (and for events, audio as well), and used EnTT for ECS. I read various sources (videos, sites, books, etc.) on how to architect an engine, the various systems, etc. Thanks also to TheCherno from which I took some knowledge and concepts/ideas.

I created a sandbox project, called AngryBird (yet another Flappy Bird clone) to demo the engine. Also, the engine supports native C++ scripting (at compile time) to add behavior to entities.

Dependencies

Getting Started

• Clone recursively this repository.
• Run WinGenProject.bat file found in scripts folder.
• Launch tsEngine.sln.

Things I might add

• [WIP] Simple game/level editor

Click me


• Dynamic (runtime) C++ script loading.
• Particle system
• Box2D

Notes

• The repository is updated, most of the time, using amend (don't ask why).
• Currently works/tested ONLY on Windows.

Issues

• [Engine] Some unnoticed memory leaks possibly.
• [Engine/Sandbox] UI text flickering. (Fixed: 1/12/21)
• [Engine] Physics colliders size if different than initial (Fixed: 28/1/22).
• [Editor] On window resize or maximize, ImGui (and viewport) don't get resized/aligned properly (maybe switch to ImGui docking?) (Fixed: 25/4/22)
