Recreated Bloons TD5, the beloved tower-defense game where you deploy and upgrade monkey towers to pop relentless waves of balloons, using my own custom content-driven C++ game engine with JSON for all game objects and behaviors.

Here are the core systems I built for this project:

Prefab Service:
– Easily register and instantiate reusable “prefabs" for game objects and behaviors straight from JSON.

Node-Based Pathfinding:
– Define your bloon paths as a simple list of nodes and inherit from the path follower component to gain pathfinding behavior

Grid Service & Level-Design Tool:
– Divide the playfield into configurable cells, mark “invalid” tower
zones in real time, and feed that same data into…

Collision Service (Uniform Spatial Partitioning):
– Bucket colliders by grid cell, so towers only check nearby bloons instead of every single one, dropping the collision test cost from O(N²) to approximately O(N) where N is the number of colliders
