TODO list

Things to do (or maybe not), generally ordered by priority

Practice setup improvement

Basically, rebrand it as a 'chart viewer' which can be used in conjunction with the k-shoot mania editor.

• Mouse-friendly UI
• Remove assumption that mapTime >= 0 (a big bug)
• Adjust/preview zoom parameters on-the-fly
• Enable refreshing chart / lua script
• Enable changing gameplay settings such as RAN&MIR
• Presets for chart range

Improve KSH support

• Fix zoom values working differently from k-shoot mania
  • Initially thought that it's just a ksh version issue, but turned out that
  • Note: Camera logic for USC vs. KSM

zoom_bottom=300 zoom_top=0

Following is a list of suggestions for the KSH spec, and not for either USC, KSH, or the KSH editor.

• Add scroll_speed and center_split to the spec
• Add bezier curve defs for lasers and zoom variables (something like bezier-a_laser-l=0.5)

Settings improvement

• Input preset for keyboard / controller
• More sophisticated offset calibration
  • Show delta bar instead of just listing delta values
  • Implement audio calibration mode (blindfolded play), video calibration mode (muted play), and sync mode (sync audio and video)
  • Statistics-based offset calibration
  • Better calibration music
  • Implement calibration using microphone (experimental)
• Profile management (create/rename/reset/delete profiles)

UI improvement

• Create functions for better pop-up display
• Better UI navigation
  • Title: Navigation using arrow key
  • Enable using mouse to navigate
  • Do something with "hidden" keys (F12 for opening the folder of a chart, tilde for practice mode, ...)
  • Do something with currently-awkward practice mode setup
• Add in-game delta display for the default skin
• Improve delta display for the result screen
• Refactor default skin's Lua codes
  • Extract common functions to another lua file (using dofile or something similar)
• Better manual chart offset adjustment
  • Enable for skins to set chart offsets in the result page (create a Lua API)
  • Devise a way for users to set chart offsets in the result page (implement it in the default skin using above API)

Lua improvement

• Make print do something (to aid in development of skins / NotUSC)
• Better Lua error display
  • Show Lua error messages as pop-ups (can be hidden)
  • SHow better stacktraces

"NotUSC" support

For background / foreground lua scripts:

• Make current scoring info (combos, # of crits/nears/errors, ...) available
• Add LoadSample function to load chart-specific sound samples
• Add a version of gfx.ImageRect which can draw partial image
  • Reference: CanvasRenderingContext2D.drawImage on HTML5
  • Using gfx.IntersectScissor is super annoying.
• Make chart data / RANMIR info (which lane goes to which button) available
• Enable toggling score/gauge/... displays
• Add support for rendering videos
  • Which format to use? - by Drewol
  • How to make an API that's easy to use and performant?

Nautica integration improvement

• Fix a problem where archives with nested folders are not extracted correctly.
• Implement search functionality
• Handle interrupted downloads
• Implement 'download all in this page' (if puddi doesn't hate it)
• ESC closes level selection / etc overlay instead of exiting the download page

I18N support

See PR #455

Scroll speed improvement

• Compute and store "earliest appearance time" to properly support negative scroll speeds for GetObjectsInViewRange and GetBarPositionsInViewRange
• Decide what to do with long notes / lasers on negative playback speed

Misc improvements/suggestions

• Make CMOD non-storable (similar to autoplay)
• Better offset computation
  • Use FFT for convolution
  • Store info on whether the offset is manually adjusted
• Keep playing the music after gameplay (like the click-the-circle game)
• Improve how input commands work (note: conflict with PR #543)
  • A command should be tied to a combination of buttons (controller or keyboard)
• Implement dual-mice on Linux
