Martijn Hagenaars
C++ Game Engine Programmer
Hi there! My name is Martijn Hagenaars. I am a
student at the Breda University of Applied Sciences
where I'm studying Game Development and focusing mainly on
game engine development in C++.
I first started programming in 2020 and have enjoyed it ever since. I have always been interested in learning about new concepts and tackling challenging tasks .
During my studies, I work on large group projects where good communication is key . During these projects, we use Scrum processes to ensure that the team can work as efficiently as possible. In some projects, I have taken on the role as programming lead , where besides implementing features, I also ensured that scrum processes were being followed and that all team members were on the same level.
I have also worked on several solo projects . During these projects, I can work efficiently and in an organized manner in order to create large applications.
After graduation, I want to continue working on game engines in the games industry .
Project Timeline
Below are some of the projects that I worked on over the last
couple of years.
On the Bubble
Type:
Custom Engine
Duration:
1 year
Platforms:
Windows, PS5
Tools:
C++
Team role:
Engine programmer
Team size:
13
Release date:
Q3 2024
On the Bubble is a custom game engine with the goal
of creating a monkey-ball-inspired game for Windows
and PS5, using raytracing, custom physics and a
custom level editor. For this project, I am mostly
focusing on engine development. My biggest
contributions so far have been for systems for
creating, updating and handling game objects, as
well as implementing a custom serialization and
deserialization system using prefabs. This project
is currently in development.
LAGGED
Type:
Game Engine
Duration:
16 weeks
Platforms:
Windows
Tools:
C++
Team role:
Programmer
Team size:
1
Release date:
2024
LAGGED (which stands for “Learning About Graphics
and Game Engine Development”) is a custom game
engine project where I try to learn new things about
certain topics in graphics and engine development.
In this project, I’ve been researching and
implementing GLTF model support, as well as
procedural terrain generation. The goal is to
implement a procedural city generator. This project
is currently in development.
Ruckus & Rascal
Type:
Game Project
Duration:
16 weeks
Platforms:
Windows (itch.io)
Tools:
Unreal Engine 5.1
Team role:
Lead programmer
Team size:

Grab a friend and start your journey in this chaotic
co-op adventure where you play as two devious
raccoons who love causing chaos. Use each other's
strengths to make your way through the diner towards
the head chef, and teach him a lesson for screwing
up your home. But be careful, the diner's staff
doesn't like you messing with their property, so
they will try to catch you!
EGO Engine
Type:
Custom Engine
Duration:
16 weeks
Platforms:
Windows, Xbox
Tools:
C++
Team role:
Engine and tools developer
Team size:
6
Release date:
January 20, 2023
EGO Engine is a custom game engine, specifically
designed for metroidvania-style games. The engine
runs on both Windows and Xbox One. For this project,
I worked on implementing the ECS (using Entt),
creating a system for loading and updating the
level, saving and loading level data using Cereal (a
serialization library), as well as tools for
creating and decorating the levels.
Astrohaunt
Type:
Game Project
Duration:
8 weeks
Platforms:
Windows
Tools:
Unreal Engine 5.0
Team role:
Enemy and AI programmer
Team size:
13
Release date:
July 1, 2022
Get ready to blast off for a spookily
extraterrestrial experience! An overly ambitious
scientist’s experiment has gone horrifically wrong,
and his mansion has been transported into space. It
is your duty to rid the mansion of a horde of
restless ghosts. Take over the different ghost’s
powers to benefit you in your traversal through the
scientist's mansion: Boost your health, increase
your shot number, and gain new powers by trapping
the ghosts in a fast-paced and immersive minigame!
Clear as many floors of the mansion of ghosts as
possible and de-haunt the cosmos! See you in space,
Astronaut!
Dungeon Crawler on a Raspberry Pi
Type:
Game Engine
Duration:
8 weeks
Platforms:
Linux
Tools:
C++
Team role:
Programmer
Team size:
1
Release date:
April 14, 2022
A 3D dungeon crawler game, inspired by the classic
arcade game “Gauntlet”, running on a Raspberry Pi 4.
This project uses 3D graphics using OpenGL, support
for diffuse and specular textures, Phong-based
lighting from multiple sources and .obj model
loading. It also uses the Bullet library for
physics, as well as ImGui for the UI. For the
gameplay, it contains a procedural dungeon
generator, two different player classes and three
unique enemies.
CPU Raytracer
Type:
Raytracer
Duration:
8 weeks
Platforms:
Windows
Tools:
C++
Team role:
Programmer
Team size:
1
Release date:
January 28, 2022
A CPU raytracer, where primitive objects, like
spheres and spheroids, can be rendered in real time.
Primitive objects can contain reflective and
refractive materials. In order to accomplish
real-time framerates (around 20fps), a custom BVH
system was implemented, as well as a multithreading
system for spreading rendering workload across
multiple threads.
Recreation of R-Type
Type:
Game Project
Duration:
6 weeks
Platforms:
Windows
Tools:
C++
Team role:
Programmer
Team size:
1
Release date:
November 5, 2021
A recreation of the first level from the classic
arcade game “R-Type”. This project tries to recreate
the first level as closely as possible, containing
many of the same enemies, upgrades, and level
layouts. This was the first project at BUAS and was
used to introduce us to C++ game development. Even
though this was the first game project that I worked
on, I still managed to implement various interesting
mechanics, like per-pixel collision, spline-based
movement for certain enemies and the FABRIK
algorithm for the boss fight at the end of the
level.
