- Closes https://github.com/ppy/osu/issues/37757
Commit-by-commit reading is recommended. Commits will be split to PRs on
request but I consider this to be the minimal viable functional
increment.
## Done
- This adds a first version of a full storyboard encoder
(a66dc406f498e35d4e0c8f2a462e946a9a1aeccc). I expect there to be hiccups
due to weird corners of the `.osb` format; this is only intended to be
somewhat correct as a start to build upon. Storyboarders are asked to
file issues as necessary.
- Due to the fact that storyboard definitions can reside both in the
`.osu` and the `.osb`, b60698a95c4de1bfeb36fbb159fd5a6028920832 adds the
required storage to be able to tell which storyboard element lives
where, so that it can be decoded properly later.
- In c9d3e04a4135886b5b0943c85f3cc6f4fe99c84c, the storyboard decoder is
weaved into the beatmap decoder to handle the `.osu` part of the
storyboard, via the
`LegacyStoryboardEncoder.Encode{General,Events}ToBeatmap()` methods. For
`.osb`s, `LegacyStoryboardEncoder.EncodeStandaloneStoryboard()` is
intended, but for now is not used outside tests.
- Because of the above, dd1c4e43dc51154cd67860f096712f8b4f229661 removes
`Beatmap.UnhandledEventLines` as no longer required.
- 26ac417ed98a8937c42e5f52c4e15ef065a48902 adds tests. They are mostly
handwritten to ensure basic encode-decode roundtripping. Using existing
storyboards is difficult, see "Known issues" section as to why.
- 5cc542366db7caac38eb0729260d884905a2c0d5 fixes a bug in the storyboard
decoder where the trigger group number was not properly negated on
decode (see inline comment reference to relevant stable code).
## Known issues
- Any and all variables in the `[Variables]` section are inlined into
their usages by `LegacyStoryboardDecoder`, and as such
`LegacyStoryboardEncoder` will end up inlining them and discarding the
`[Variables]` section. As far as I can tell stable will also do this.
- `LegacyStoryboardDecoder` splits all `M` (move) commands into
`MX`/`MY` commands. Therefore, `LegacyStoryboardEncoder` will write out
things in the same split way. I did not put in effort to attempt to
reconcile this, for reasons of part laziness, part not wanting to bloat
this already-large diff.
- Ordering of storyboard samples on decode may not match the order on
decode. I'm crossing fingers this doesn't matter.
It's been a while.
Notes:
- `SharpCompress` usages changed a bit. Manually adjusted these, mostly
just renames or adjusted parameters.
- nUnit 3 -> 4 migrated using
https://gist.github.com/peppy/07994386d793a117350cb5f24b156585. there's
a mode in this script to update to the newer `Assert.That` syntax but it
requires fixes and couldn't really be bothered.
- DeepEqual nuked as the only usage was on a disabled test. The reason
it's disabled has been merged upstream, but it's failing for other
(realm) reasons which I don't think is worthwhile to investigate for
now.
- This bumps Moq. I think the author is back in a sensible headspace and
the new version has the stupid shit removed, so probably okay? Nice to
be on a level playing field with packages for once in a long time.
- Automapper is silly, but we've discussed this elsewhere.
- `TestRealmKeyBindingStore` failures are a wildcard, but fixed by using
a more standardised testing method. Dunno why, don't care.
