Animation Manager

To make it easier for my group to add animations, I created a stack-based animation system. Animations are pushed onto the stack and popped based on set conditions.

For example, an idle animation is pushed first and set to stay indefinitely. When the player starts walking, a walking animation is pushed on top, overriding the idle animation. Once movement stops, the walking animation is popped, revealing the idle animation again.

This system ensures smooth transitions and makes managing animations simple and flexible.

The feedback I got for this was amazing!

Collision System

We needed a way to check if objects, like bullet projectiles were hitting the target and the player were within specific regions in the game. I implemented Oriented Bounding Box (OBB) collisions. This allowed for more accurate collision detection, especially with rotated objects, compared to simple axis-aligned bounding boxes.

I used matrix transformations to perform OBB vs. OBB and OBB vs. sphere checks, incorporating the separating axis theorem (SAT) for precise results. This system proved crucial for handling interactions in the game, ensuring efficient and accurate detection for bullets and event triggers.

PBR

I wanted to deepen my knowledge of light physics and how it interacts with materials. This showcase is one of the earlier iterations of development, demonstrating key aspects of Physically Based Rendering (PBR), such as Fresnel reflections, and roughness-based light scattering. Even at this stage, the foundation for realistic lighting was already taking shape.
