This PR adds `genpe.tja` to the test suite, a song that currently fails
due to how `tja2fumen` handles `#SECTION` commands.
We fix the problems with branching commands in
8ad2102f0a. (Making sure that any #SECTION
commands that occur before the first #BRANCHSTART are properly handled.)
This PR also contains a few refactoring commits to improve the clarity
of how the branching logic works, to make further debugging of branching
songs easier.
Fixes#33.
This PR adds a new chart to the test suite (`imcanz.tja`) that uses
`p,0,0`, `p,999,999` _and_ `#SECTION` commands:
- `p,0,0`: Forces the chart into the Master branch (since it's
impossible to fail a 0% accuracy requirement)
- `p,999,999`: Forces the chart into the Normal branch (since it's
impossible to pass a 999% accuracy requirement)
- `#SECTION`: Resets accuracy values for notes and drumrolls on the next
measure. (In practice, this just means that the branch condition is
repeated on the next measure, at least according to the official fumen I
have.)
Note: Only the Oni and Hard difficulties have actually been added to the
test suite. The Normal and Easy charts were too broken to easily match
the official fumens. They will need a lot of work to fix charting
errors, so I'm leaving them commented out for now.
Fixes#27.
- Before: 'OFFSET' = 2nd measure fumenOffset
- After: ('OFFSET'-Full measure duration) = 1st measure fumenOffset
Both methods will produce the same results if no #MEASURE/#BPMCHANGE
commands are present in the first two measures. However, if these
commands ARE present, then you will get wildly different results.
This change doesn't affect 4/6 tests, but for 2/6 tests there were
#MEASURE/#BPMCHANGE commands. For these songs, I had erroneously "fixed"
the OFFSET values, when they were correct all along. So, I reverted them
back to their original values.
Fixes#25.
This PR adds support for multiplayer charts, and adds a new multiplayer
TJA/fumen combo for testing.
This PR is quite small, because the only work that needed to be done is
parsing the course metadata. Once the TJA lines are split into courses,
the actual course-by-course parsing logic is identical to the songs that
came before.
Fixes#6.
This PR adds the remaining changes needed to support branching TJA
songs.
- Properly handling `r` (drumroll) based branching conditions
- Handling commands that come after a measure end but _before_ the first
`#BRANCHSTART` command. (This was not previously covered by
`hol6po.tja`.)
As well, it adds a bit of cleanup/refactoring to the changes from the
previous branch PR (#20).
To test these changes, another new branching TJA-fumen pair is added to
the test suite.
The official fumen had some issues where a note ended up in the wrong measure:
- Expected: pos 0.0 on the next measure
- Actual: pos 645 on the prev measure (impossible pos)
They're the same pos, but only pos 0.0 is possible to express in TJA charts, so the fumens themselves had to be updated.
Also, the TJA chart had errors, too:
- The BPMs/SCROLLs in the BPMCHANGE section were incorrect
- Some drumrolls were too short
Fixing these errors caused the failing test to pass.
