An Automated Map Generator for Rhythm Platformer (11/2020) - Solo

Team size: 1

Engine: Unity

Status: Finished

Project page: View it on GitHub

Introduction:

Using spectral flux algorithm, this beat map generator can analyze any songs selected by player and generates a beat pattern. As long as the program can read the beat pattern, any rhythm games can make use of it. The project contains a simple rhythm game that is coded by myself.

Work on:

  • Analyze

    Use fast fourier transform in DSP lib to convert the sample data we get from AudioClip to spectrum data. Divide a song into small parts, and calculate the average of each part. Then keep the data that can be used for next step.

  • Generate

    Analyze the pattern of the beat within a period of time, then if necessary, combine multiple beat into one or combine the beat with the blank space and group them together into one obstacle.
