Spawn an exit ship when the player approaches an exit zone. The ship flies in, lands near the exit, and waits for the player to board. On boarding the player is deactivated, the ship takes off, and the level transition fires after departure.

# TODO
|
|
|
|
## ~~Distance-based sound effects~~ ✓
|
|
Implemented: `audio_set_listener()`, `audio_play_sound_at()` with linear
|
|
attenuation and stereo panning. Used by enemy death, asteroid impact, and
|
|
powerup pickup.
|
|
|
|
## ~~Spacecraft art and entity~~ ✓
|
|
Implemented: spacecraft PNG spritesheet (5 frames, 80x48 each), full entity
|
|
with state machine (FLYING_IN → LANDING → LANDED → TAKEOFF → FLYING_OUT →
|
|
DONE), engine/synth sounds, thruster particles, level intro sequence with
|
|
deferred player spawn.
|
|
|
|
## Large map support (5000x5000)
|
|
Audit the engine for anything that breaks or becomes slow at very large map
|
|
sizes. Key areas to check:
|
|
- Tile layer allocation (`uint16_t *` for 25M tiles)
|
|
- Tilemap rendering culling (already viewport-clipped, verify correctness)
|
|
- Physics / collision queries (should only check nearby tiles)
|
|
- Entity updates (currently iterates full pool regardless of distance)
|
|
- Camera bounds and coordinate overflow (float precision at large coords)
|
|
- Level file parsing (row lines could exceed fgets buffer at 5000+ columns)
|
|
|
|
## ~~Spacecraft at level exit~~ ✓
|
|
Implemented: `spacecraft_spawn_exit()` with `is_exit_ship` flag. Proximity
|
|
trigger in `level.c` spawns exit ship when player is within ~2 screen widths
|
|
of an exit zone. Ship flies in, lands near exit. Player overlaps landed ship →
|
|
player deactivated, ship takes off, camera holds still, level transition fires
|
|
after ship departs (SC_DONE).
|
|
|
|
## ~~Asteroid refinement~~ ✓
|
|
Implemented: base speed 120→200, accel 200→350, respawn 3→6s, stagger 0-3→0-8s,
|
|
random horizontal drift (±60 px/s), moon level reduced from 24 to 8 asteroids.
|
|
|
|
## Moon campaign: 3 levels with spacecraft transitions
|
|
Extend the moon into a 3-level sequence connected by spacecraft takeoff/landing:
|
|
- **moon01.lvl** — Current level. Exit triggers spacecraft takeoff, transitions
|
|
to moon02.
|
|
- **moon02.lvl** — Second moon level (new terrain, new hazards). Starts with
|
|
spacecraft landing intro. Exit triggers takeoff to moon03.
|
|
- **moon03.lvl** — Third/final moon level. Starts with spacecraft landing.
|
|
Exit triggers takeoff and transitions to level01 (space station).
|
|
- **level01.lvl** (space station roof) — Starts with spacecraft landing on the
|
|
station rooftop. Ship stays landed (no takeoff). First armed level.
|
|
- Moon exit transitions require the "spacecraft at level exit" feature so
|
|
the ship flies in when the player approaches the exit zone.
|
|
|
|
## Level generator: height zones (verticality)
|
|
Add vertical variety to generated levels using a "height zones" approach:
|
|
- Double tilemap height from 23 to ~46 tiles (two screens tall)
|
|
- Define two elevation bands: HIGH (ground ~row 17) and LOW (ground ~row 40)
|
|
- Existing segment generators get a `y_offset` parameter so internal logic
|
|
barely changes — platforms, enemies, corridors all shift by offset
|
|
- New vertical connector segments (ramps/climbs) bridge between zones
|
|
- Theme decides zone usage: Surface stays LOW, Station uses both, Base uses HIGH
|
|
- Camera needs vertical look-ahead when player has vertical velocity
|
|
|
|
### Implementation steps
|
|
1. Add vertical camera look-ahead (small Y lead when player moves vertically)
|
|
2. Create a handcrafted tall test level (~40x46) to validate camera, physics,
|
|
rendering, and entities all work with vertical scrolling
|
|
3. Refactor `set_tile()` / `fill_ground()` to accept a height parameter instead
|
|
of hardcoded `SEG_HEIGHT`
|
|
4. Add `y_offset` parameter to all segment generators
|
|
5. Add `SEG_CLIMB` connector segment type (shaft/platforms between zones)
|
|
6. Update `levelgen_generate()` to assign zones per segment and insert climbs
|
|
7. The station generator stays at 23 tiles (corridor envelope already constrains)
|
|
|
|
## Jetpack boost blue flame effects
|
|
- Add continuous blue flame particles trailing from the player during jetpack
|
|
boost (while boost is active, not just on burst)
|
|
- Add blue accents to the jetpack burst effect itself — mix blue flame particles
|
|
into the existing yellow/orange exhaust plume
