About This Course

This course takes help you in creating a fast-paced 2D gameplay while ensuring your game performs smoothly. Using the Object Pooling design pattern, you’ll learn to handle rapidly spawning and destroying entities like bullets, enemies, and power-ups without overloading your system.

You’ll start by implementing a bullet object pool to optimize their creation and destruction, then move on to building generic object pools for reusability across other entities. As you progress, you’ll handle subtypes for power-ups, enabling diverse behaviors without duplicating code. Alongside these optimizations, you’ll implement screen wrapping for both your ship and bullets, and design an immersive arcade experience with randomized power-ups and waves of enemies. By the end, you’ll have an exciting 2D space shooter and the skills to optimize any game for performance.

Hello everyone!

I'm delighted to share that I'm starting my new journey with Outscal's Full Stack Game Development program! 👾

Ever since I first picked up an Atari controller as a kid, I've always had a passion for gaming. Besides gaming on PC, the next consoles during my childhood were a Game Boy Color and a Nintendo 64. The immersive worlds, the strategic gameplay, the storytelling — everything about gaming has captivated me since then. I love playing RPGs, card games, and anything that lets me get lost in a story or challenges my mind. I have always been a creator of sorts, creating my own budget board games, characters, and so on.

My trajectory to where I am now was far from the usual one. From graduating in Japanese Language, graduating from a Flight Attendant School, and experiencing the backdoor of players' game experience as a Mobile Game Customer Support, every step has brought me closer to this decision. After much thought, I decided to dive into the gaming industry and turn my passion into a career!

I'm incredibly excited to start this journey and while it may be a bit of a big dream of mine, I wish to create games that not only entertain but also inspire people as much as I've been inspired throughout my life by games.

Fun fact, my work setup can be seen in the photo and it includes a special spot for my comrades in gaming. 🐱

David Rogers

Aspiring Software Developer | Information Technology Graduate | Passionate About Building Innovative Solutions

Today, I am beginning my journey to become a game developer with Outscal's Full Stack Game Development program.

I've always known that I wanted to do software development. I've always been passionate about playing video games and fiddling with technology since I was a kid too. I surprised even myself when I obtained my bachelor's degree from the University of Phoenix in September after multiple obstacles. I proved to myself that no matter how bad things were, I've always found a way to improve myself.

With that in mind, I decided to pursue game development. I'm really excited to start! With my decent setup, and unopened Warhammer minis, I'm confident I'll succeed here too!

I wanted to sincerely thank Mayank Grover for helping me get into the program by offering me a plan that works for me to pursue my dream.

Game Developer | 3D Artist | Outscal

Hello, Connections! I’m thrilled to share that I’ve embarked on a new adventure with Outscal’s Full Stack Game Development program.

As someone deeply passionate about playing games and bringing creative ideas to life through 3D art, I’ve always been fascinated by the magic behind games. Spotting little details in games sparked my curiosity about how these incredible experiences are crafted. This curiosity has now turned into a goal—to create games that inspire, entertain, and leave a mark. Joining the gaming industry feels like a natural step to combine my love for creativity, technology, and storytelling.

I’m super excited to learn, grow, and connect with like-minded individuals in this amazing field. Here’s to building something extraordinary—one line of code and one pixel at a time!

Hello World!


This is a First-Person Hunter type Game. Developed this project in 4 days for Outscal's MAT assignment.


GitHub project link: https://lnkd.in/g4Ci29Gw

Playable Game link: https://lnkd.in/gXUHhnKw


Design Patterns ☟

  • Generic Singleton: Created Generic Singleton and made Service script as Singletons from Generic Singleton.
  • MVC-S: Created Model View Controller for Enemy, Weapon, and Bullet.
  • Scriptable Objects: Scriptable Object to store all different Enemy, Weapon, and Bullet data.
  • State-Machine: State Machine for Enemy to do assigned tasks only for that State.

Game Functionalities ☟

  • 3 types of Weapons: Single Pistol, Double Pistol, and Sniper.
  • 4 types of Enemies for Hunting.
  • Player can choose their Weapon and Enemy from Lobby.
  • Player can move into the world freely, but movement speed will be reduced according to Weapon weight.
  • Enemy will Patrol until Player enters the range.
  • No health for Player; if the Enemy reaches the Player, they will be Dead.
  • Different hit areas can reduce different damage for Enemy.
  • Zoom functionality for Sniper.

I am a developer specialized in C# and Unity, with considerable knowledge in c++, Unreal, Java, Javascript, Node.Js, Angular and React

I’ve started the State Machine Pattern module in the Game Development Advanced course at Outscal! ⚙️

The State Machine Pattern is a fundamental approach in game development for managing different system states, such as character animations, AI logic, or game phases.
It helps organize and control transitions clearly and efficiently, reducing code complexity.

I’m excited to dive deeper into this pattern and see how it can make my projects more robust and scalable!

Hello everyone,

I want to share an update on the project "Home Calling" that I have been working on as a part of Outscal Gamejam.

I have created a 3D Hack and Slash game which features 2 playable characters.
To create the project, I have used State Behaviors for the enemies and Animation Events for characters.

I would like to thank my mentors Mayank Grover and Malhar Devasthali from Outscal for guiding me and helping me in creating the project.
I would also like to thank my clanmates who constantly supported me throughout the project.

You can download the project from the link below and share your feedback and suggestions, as the project is still in development.
