- Line 66: Update the collision_layer/collision_mask entries in the
documentation table to mark both members as required and state that missing
members raise TypeError; revise the sample class comments for these assignments
to remove the stale optional/default implication and identify collision_layer as
required.
In `@src/tilemap_parser/parser/particle.py`:
- Around line 37-42: Update _to_int to remain non-throwing for all numeric
inputs: reject bool values before conversion, catch OverflowError alongside
TypeError and ValueError from int(raw), and remove the math.isfinite(value)
check that can overflow for large integers. Return the converted integer for
valid inputs and default for rejected values.
In `@src/tilemap_parser/parser/tileanim.py`:
- Around line 149-150: Update the non-looping end-of-playback branch in the tile
animation parser to return the final frame from the phase-rotated playback
order, using phase and n rather than the original-order index. Add coverage for
a non-looping clip with a nonzero phase and verify the final frame remains held
when time_ms reaches total.
In `@src/tilemap_parser/runtime/particles.py`:
- Line 763: Update the pending-burst scheduling flow around trigger_burst and
update so each scheduled burst stores the trigger rectangle (area_x, area_y,
area_w, and area_h) when created, then passes those stored values to
emitter.emit_burst for every pop instead of using the latest update rectangle.
- Around line 729-731: Update the stream-spawning gate in the particle runtime
update flow so spawning is enabled only when the phase is active and config.mode
is "continuous"; keep burst handling separate through _pump_burst_pops and do
not add automatic burst behavior unless already required by the editor contract.
- Around line 718-719: Update the emitter timing logic around the MAX_DT clamp,
self.clock advancement, and burst scheduling to use the full nonnegative elapsed
delta; reserve the clamped delta for particle physics only. In the loop-expiry
path, subtract the completed cycle duration from self.clock instead of resetting
it to zero, preserving overshoot while keeping delays, durations, loops, and
burst intervals synchronized.
In `@tests/test_v6_contract.py`:
- Around line 64-70: Update test_base_requires_layer_and_mask and
test_sprite_adds_motion_only to use typing.get_type_hints on ICollidable and
ICollidableSprite instead of the Python-version-specific __protocol_attrs__
attribute, importing get_type_hints alongside cast.
In `@webdocs/src/pages/ApiReference.tsx`:
- Around line 121-127: Update the TilemapData.get_placed_image_layer_surface API
reference entry to show layer, render_scale=1.0, and include_hidden=False, and
document that hidden layers return None unless include_hidden=True. Preserve the
existing composition and caller-owned surface description.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Open sidecars as UTF-8.
open(path) uses the platform default encoding. On Windows this is often cp1252. A .tanim.json file with non-ASCII clip names or sheet paths then raises UnicodeDecodeError. UnicodeDecodeError is a subclass of ValueError, so line 126 catches it and returns an empty TileAnimFile. The renderer then shows static tiles, and the only sign is a generic "no clips loaded" warning. JSON is UTF-8 by specification. TilemapData.load already reads the nodes sidecar with encoding="utf-8".

Scale particle-emitter rectangles with render_scale.
_apply_tile_offset shifts node areas by unscaled tile pixels. ParticleEmitterNode copies that area without scaling, while AreaNode scales its rectangle. The particle example passes pe_node.rect directly to ParticleSystem. With a 16-pixel tile, scale 2, and offset_x=2, the emitter offset is 32 pixels but the scaled map displacement is 64 pixels.

Expand candidate-cell searches for flipped geometry.
A diagonal flip can move a non-square tile’s collision shape several grid rows outside its owning cell. For example, a full-tile polygon on a (128, 16) tile reaches y=128 after the transpose, but _collides_at searches only one row beyond a sprite near y=80. It never reads the tile in row zero, so the collision is missed. Account for transformed shape extents in the candidate-cell searches used by _collides_at, _first_colliding_shape, _collides_at_platformer, and _find_walkable_ground_info.

transformed shape rather than relying on a fixed one-row margin.

Propagate field coverage and quality to automatic refills.
ParticleField.clear() intentionally permits the field-contract refill. However, _make_config() leaves coverage at 1.0 and field_quality at "medium". refill_if_field() then uses those defaults instead of preset.coverage * self.density * quality_density, so the refill density can differ from ParticleField.refill().
Set both config values when creating each layer:

+ field_quality=self.quality,

In `@src/tilemap_parser/runtime/particles.py` at line 877, Update _make_config so
each created layer’s configuration sets coverage from preset.coverage multiplied
by self.density and sets field_quality to self.quality, allowing refill_if_field
to use the same field coverage and quality as ParticleField.refill.

Use the collision tile size for flip extents.
The map grid size can differ from the tile size. resolve_stack_entry passes self.tile_size to flipped_data, while _literal_entry_data passes tileset_collision.tile_size. For a 16-pixel grid and a 32-pixel collision tile, a horizontal flip maps a vertex at x=28 to x=-12 in a world, but to x=4 without a world. Use the collision tile dimensions for the world transform so both paths place the shape consistently. Tiled permits tile dimensions to differ from the map grid. (doc.mapeditor.org)

resolve_stack_entry to pass the collision tile dimensions to flipped_data,
matching _literal_entry_data, instead of using self.tile_size; world and
non-world flip transforms should place collision shapes consistently when map
grid and collision tile sizes differ.
