-- YataiDON-HSS child-skin addition (no parent counterpart).

|
|
-- ============================================================================
|
|
-- ROUND 96 (r96-soulgauge-cellgrid): this object NO LONGER DRAWS ANYTHING.
|
|
--
|
|
-- From ROUND 6 to ROUND 80 this file redrew the ordinary soul gauge's fill on
|
|
-- top of the engine's own, because the engine drew on an 87-cell / 12 px grid
|
|
-- while the cabinet's grid is 50 cells x 21 px, and because gauge.cpp hardcoded
|
|
-- the separator overlay at fade 0.15 where the cabinet uses Amul 77/256.
|
|
-- Redrawing on top meant this file also had to ERASE the engine's overshoot,
|
|
-- guess the difficulty from the is_clear flip so it knew which plate to erase
|
|
-- with, re-composite the separator strength in two passes, and put the
|
|
-- クリア caption back on top afterwards.
|
|
--
|
|
-- Every one of those was a workaround for the engine's grid, and the last of
|
|
-- them was also the defect the user kept reporting
|
|
-- (「soul gauge還是有錯，他的新增格數應該是一格一格，他看起來有gap」):
|
|
-- `erase()` repainted only 24 px past the arcade fill edge, but the engine's
|
|
-- own gauge-up flash `<pn>p_bar_fade` (a 24 px SOLID slab based at texture.json
|
|
-- x 732) landed at `732 + 12*floor(87*progress)`, i.e. up to
|
|
-- 18 + 12*floor(87p) - 21*floor(50p) = +33 px
|
|
-- past the true cell boundary. What survived erase() was a detached,
|
|
-- wrong-height orange fragment one cell ahead of the fill, with unfilled groove
|
|
-- in between -- the "gap". Measured live at soul 945 / 2788 / 5996 as
|
|
-- +30 / +33 / +33 px (scratchpad/r96/scan.py, crop
|
|
-- scratchpad/r96/crops/live_a_58_edge.png). Worse, past screen x 1335 with the
|
|
-- difficulty still unknown, `erase()`'s PLATE_SHARED_END clamp made its width
|
|
-- <= 0 and it returned WITHOUT ERASING AT ALL, so the engine's raw fill
|
|
-- overshoot showed too.
|
|
--
|
|
-- CORRECTION TO ROUND 19: the comment that used to stand in this file --
|
|
-- "The engine's own copy is otherwise harmless (this file's opaque redraw +
|
|
-- erase() covers it)" -- was wrong, and had been wrong since ROUND 19. It is
|
|
-- the direct cause of the report ROUND 96 fixed. ROUND 34's and ROUND 37's
|
|
-- findings about this file's OWN flash placement and about
|
|
-- Background:handle_gauge's argument count were correct and are preserved in
|
|
-- MAPPING_hud.md; they simply no longer have any code to apply to.
|
|
--
|
|
-- ROUND 96 moved the grid into the engine instead: `Gauge::draw()`'s NORMAL
|
|
-- branch now draws the fill, the transition cell, the clear-zone tiles and the
|
|
-- flash on the cabinet's own 50-cell / 21 px grid (X0 = 738, clear cell
|
|
-- 30/35/40 by clear-zone art tier), and draws the separator overlay once at the
|
|
-- cabinet's real Amul 77/256 = 0.30078. It knows the true difficulty, so the
|
|
-- plate-guessing goes away as well. There is nothing left for a skin-side
|
|
-- overlay to correct, and drawing one again can only re-introduce seams.
|
|
--
|
|
-- What is kept: the `handle_gauge` / `draw_one` hook shape (background.lua and
|
|
-- Player::draw both call them, and a future round may want the hook), and
|
|
-- ROUND 43's texture-id-contamination unload -- see below.

-- longer draws gauge textures through the script wrapper, so it can no
