Don't question my naming sense, this is a WIP Trombone Champ chart previewer
- Loads and previews
.tmbJSON files - Loads and previews base game
.tmbchart files (NRBF) - "Trombone" playback, ability to provide music playback (supports
.ogg, and likely many other things, to the extent of browser support pretty much) savednotespacingand tempo fidelity in regards to the game, (un)zooming ability- Playback rates from 25% to 200%
- Audio waveform preview for sync checks
- Lyrics and metadata editing
- Metronome
- Importing assets from remote URLs and handling hotlinks
- Possibly handle MIDI parsing (there are other tools for that)
- Tempo editing (multi-tempo support/"polyfill"?)
- Try to make this somewhat usable on mobile (lol)
- Some basic note editing features/macros? (e.g. move selection horizontally)
- Some other stuff I'll think about eventually
Install Node.js (whichever recent version is fine)
# Install yarn (optional)
npm install --global yarn
# Install dependencies
yarn (or npm install)
# Run local dev server
yarn dev (or npm run dev)I don't know man
- This is probably the weirdest way to learn about writing SVGs by hand
- I could probably think about implementing color profiles and increase fidelity in regards to the actual game and so on, but there are other better tools out there for that
- I tried to experiment with embedding compressed chart data in the URL for quick hotlinking, but it ended up way too big to be serviceable (>2000 characters)
- Use Rubber Band library [rubberband-web (wasm)] for better quality playback rate (they have a fast algorithm)
- Import/export lyrics from Clone Hero charts (lol)
- One could try to generate a difficulty map of the chart (render in the seeker?) using TootTally algorithm
