Friday Night Funkin Engine: Beat Sync and Character Creator Tool

The Friday Night Funkin Engine is a creative tool designed to help you synchronize character animations with custom music tracks. Created because the developer felt uncomfortable seeing Girlfriend and Boyfriend nodding to incorrect beats, this engine provides a solution for perfect timing alignment.

How to Use the Beat Sync Engine

Follow these steps to create perfectly synced rhythm experiences:

  1. Choose a song - Start with slower tempos to practice the beat detection process
  2. Click the "beat" sprite inside the project to access the detection interface
  3. Determine your song's beat using the instructions provided in the tool
  4. Input the beat value into GF & BF's block where it says [beat : ( )]
  5. Test and refine - If the animation doesn't match, try again with adjusted values

Adding Custom Characters to FNF Engine

Expand your rhythm creations with original characters:

  • Upload or draw your character - Import custom sprites or create new ones
  • Classify character type - GF type (nonstop moving animation) or BF type (moves and stops)
  • Set parameters - Input the beat value and number of shapes your character has
  • Complete integration - Your character will now sync with the music
