BoxMenu.lua's release() pushes both its "Once released...OK?" prompt
and its Yellow-only "Pikachu looks unhappy" message through
TextBox.new(game, (t._X or Strings(...)):gsub(...)) -- gsub returns
two values (the text and a substitution count), and since the gsub
call is the last argument in the TextBox.new(...) call with nothing
after it, Lua expands both into the call: the count lands in
TextBox.new's third parameter, onDone. TextBox.lua later calls
onDone() once the box is dismissed; a number is not callable, so
every release of your own caught Pikachu in Yellow crashed --
regardless of its nickname (unlike the separate %-escape gsub bug,
this one needs no special save content, ordinary play reaches it
every time).
Fixed by wrapping the gsub call in an extra pair of parens, which
truncates it to its first return value only -- the same fix already
applied to the neighboring _OnceReleasedText/_MonWasReleasedText
lines on the (separate, unmerged) fix/route-more-messages-through-romtext
branch, where this exact bug shape was first noticed while adding a
third callsite with the same pattern.
tests/engine/pikachu_unhappy_release_crash.lua: registers a fake
Data.pokemon.PIKACHU cloned from the fixture species (ROM-free) so
the species == "PIKACHU" check can be exercised, drives the real
interactive release flow in Yellow on a mon owned by the player, and
confirms the crash. Verified failing pre-fix (exact same
"attempt to call field 'onDone' (a number value)" error) and passing
post-fix.
The previous drawCellBottom calls fired only for cells containing a
tracked entity. While walking this worked acceptably because the
sprite's sub-pixel tween kept the visual overlap plausible, but while
standing still the sprite is pixel-aligned with the cell and the opaque
leaf-edge pixels in the grass bottom row paint over the player's feet.
This change removes the per-entity isGrassCell checks and replaces them
with a single post-sprite pass that overdraws every visible grass cell.
TileRenderer:
- ensureWindow now builds grassCells (all paths) and grassBatch (DMG/SGB
shader path) alongside winBatch during the existing tile scan loop.
A grassSeen table deduplicates cells so each cx/cy pair is only
recorded once despite having two bottom-row tiles.
- drawGrassOverdraw: DMG/SGB draws the grassBatch under color0KeyShader
in one call; GBC iterates grassCells and calls drawCellBottomRaw per
cell (pre-keyed images can't share a SpriteBatch).
- markGrassOverdrawRedraw: iterates grassCells and calls
markCellBottomRedraw for the post-zone OBP-replay pass (GBC only).
- releaseBatches cleans up grassBatch and grassCells.
OverworldController (flat path):
- Entity loop draws sprites only; grass overdraw fires once after the
loop via drawGrassOverdraw + markGrassOverdrawRedraw.
OverworldController (tilt path):
- Grass cells are injected into the billboard sort queue keyed on the
world-pixel foot of each cell's bottom tile row (cy*16+16), so they
depth-sort correctly against entities at different y positions. Each
grass cell billboards via drawCellBottomRaw inside the upright pass.
Fixes: standing-in-tall-grass feet overdraw (Gen 2 confirmed, Gen 1
improved); NPCs and Pikachu follower in grass benefit automatically.
Parity test: tests/parity_grass_seam.lua 10/10, engine 228/228.
The takeover stop in Sound.playMove moved after the new source starts in
cfa84063, but an equal-id replay reuses the cached source, so the stop
killed the sound it had just restarted.
