CrossyAnt

A Frogger/Crossy Road-inspired game with a hand-rolled 2D engine — custom collision detection, sprite rendering, and task scheduling, no game engine underneath any of it.

Source

Built at LSU as a first serious engineering project, modeled on Frogger and Crossy Road: dodge traffic, collect coins, spend them on power-ups and debuffs, survive.

There's no game engine underneath it — Swing provides the window and the paint surface, and everything from there is custom: a collision handler tracking sprite bounds, a sprite-component system for rendering and animation state, and a decoupled task scheduler running spawn timers, buffs, and the clock independent of the render loop.

It's archived because it's finished, not because it's disowned — the collision and scheduling code is the part worth showing, and it hasn't needed touching since it shipped.

What it does

Custom 2D collision detection between the player, enemies, and hazards
Sprite rendering and animation pipeline built on Swing's paint surface
Decoupled task scheduler driving enemy spawns, timers, and power-up buffs
In-game currency, shop, power-ups, and debuffs
High-score persistence

What it taught me

Structuring a real-time render loop without a framework underneath it
Decoupling game timing from rendering so one can't stall the other
Object-oriented design under the constraint of an actual deadline
