Synth Mapping Helper

Toolbox for manipulating the JSON-Format used by Synth Riders Beatmap Editor in the clipboard.

Features

• Filter by note and wall types for all operations
• Changing colors
• Change BPM indepenent of note timing
• Movement in XY and Time:
  Note: All operation can be done in regards to grid center, a pivot point, or the start of rails
  • Rotate
  • Scale and mirror
  • Outset (moving outwards/away by a fixed distance)
  • Offset (Translate/Move)
• Pattern generation
  • Spirals/Zigzags
  • Spike/Buzz-Rails
  • Stacking patterns with movement
• Rail manipulation
  • Merging
  • Splitting
  • Interpolation
  • Convert between single notes and rails
• Cross-Platform (Windows, Linux)
  • For Windows, supports drag and drop actions (fully usable without command prompt)
• Imports directly from clipboard, and export to it
• Uses an internal format that is easy to work with:
  • Position in editor grid coordinates (+x=right, +y=up)
  • Time in measures (starting from start of selection)
  • Angles in degrees (positive=counterclockwise)
  • Notes/Rails seperated by color and as n x 3 numpy-arrays (x, y, time)
  • Walls as 1 x 5 numpy-arrays (x, y, time, type, rotation)
  • Walls positions are adjusted to match their rotation center

Maybe

• GUI
• Momentum analysis
• Automatic smoothing

How to Install and use

Advanced users

• Install via pip3 install synth_mapping_helper (requires python 3.9 or higher)
• See python3 -m synth_mapping_helper.cli -h for usage
• Feel free to experiment with extending functionality by using the module functions directly. If you have something that you think could help other mappers, please make a PR

Windows

Installation:

• Install Python 3.10 via the store: https://apps.microsoft.com/store/detail/python-310/9PJPW5LDXLZ5
• Download the windows_helpers.zip from the releases page
• Extract it somewhere
• Double-click install.bat to download the library and dependencies

Updating:

• Optional: Download windows_helpers.zip again (backup your custom actions before you overwrite)
• Run install.bat again

Usage:

• Copy the notes from the editor with CTRL-C
• Drag an action text file like merge_rails.txt or spiralize.txt onto smh.bat to execute.
• Paste the result into the editor with CTRL-V

Making your own actions:

• Run show_help.bat to learn which options are supported
• You can specify multiple different operations in the same line, they will be chained in the order they appear in the help (ordering of options in the line has no effect).
• If you want a different order, or want to do the same operation multiple times (ie different offsets for two colors), each action file can contain multiple lines which are executed in sequence
• Each line is an independent command, so ie a pivot specified in the first line does not affect the second lines
• If you made a particularly useful action, feel free to share it so it can be added to the examples
