Rail Sweeper

01Situation

Course project for AI For Game Programming at UCF requiring integration of game AI systems with an original game concept, complete with a full gameplay loop.

02Task

Design and build a polished 3D rhythm game featuring MIDI-driven note spawning, AI-based difficulty scaling, and player progression tracking.

03Actions

• ▸Implemented MIDI-driven note spawning using the Melanchall DryWetMIDI library — reading note positions from a custom MIDI file, with BPM-based beat tracking for frame-perfect accuracy without manual note placement.
• ▸Built an object pool for note GameObjects to minimize active scene object count and maintain consistent performance.
• ▸Integrated game AI that tracks player combo score — higher combos increase note travel distance and speed for dynamic difficulty.
• ▸Generated note patterns from a graph structure of predefined patterns (spirals, diagonals, zigzags) for varied, playable challenge.
• ▸Designed and scripted all UI including level select with per-difficulty completion stars and end-of-song stat display.
• ▸Modeled and integrated all visual assets and audio elements.

04Results

• ★Complete gameplay loop with scoring, dynamic difficulty, and persistent player statistics.
• ★Beat synchronization accurate to 1/16 note resolution.
• ★Available for download on itch.io.
