Personal

Occasionally, I do pet projects for fun. These projects can be anything. Some of them are pieces that I find interesting at work. Some of them are just learning, research and experiment. Some of them are improvements to existing solutions, both mine and others. Some of them are tutorials for things that I made mistakes before and I want to share that painful experience.

Learn graphics programming (WIP)

  • Follow learnopengl.com as I have absolutely zero idea how to write a renderer from scratch.
  • Learn about graphics pipeline, texture, vertex, shader, buffers, lighting, camera and a lot of other basic stuff.
  • Occasionally going off route by spending way too much time designing engine subsystems…

Unity-EnTT

  • Continue with EnTT, this time with Unity.
  • Write a very simple tower defense logic layer in ECS with EnTT.
  • Link: https://github.com/tongtunggiang/unity-entt

Rewrite my first game in university with C++ and SDL using ECS architecture

  • Rewrite my first game: same gameplay, same horrible mechanics, new ECS practices (powered by EnTT).
  • Link: https://gitlab.com/TongTungGiang/GreenSwordfish

ECS Experiment with Unity

  • Use Unity 2019.3.
  • Write two demos: one in traditional Mono and the other one in ECS and throw many agents to the scene.
  • Performance comparison.
  • Learn the uniform grid spatial partitioning technique and implement it in ECS using multi hash maps.

Line of Sight Implementation in UE4

  • Use Unreal Engine 4.18.
  • Playing around with UE4’s procedural mesh generation.

An Object Pool solution for Unity 3D

  • A common optimisation practice.
  • Data-driven workflow friendly allowing quick setup.
  • Should be applicable on most Unity versions.

A C#-inspired event and delegate implementation in C++

  • Built on the foundation of the Observer pattern.
  • Featuring function pointers encapsulated in a class.
  • … and a colourful output window just for fun.
