Implement four feature phases: Phase 1 - Pause menu: extract bitmap font into shared engine/font module, add MODE_PAUSED with Resume/Restart/Quit overlay. Phase 2 - Laser turret hazard: ENT_LASER_TURRET with charge/fire/ cooldown state machine, per-pixel beam raycast, two variants (fixed and tracking). Registered in entity registry with editor icons. Phase 3 - Charger and Spawner enemies: charger ground patrol with detect/telegraph/charge/stun cycle (2s charge timeout), spawner that periodically creates grunts up to a global cap of 3. Phase 4 - Mars campaign: two handcrafted levels (mars01 surface, mars02 base), mars_tileset.png, PARALLAX_STYLE_MARS with salmon sky and red mesas, THEME_MARS_SURFACE/THEME_MARS_BASE for the procedural generator with per-theme gravity/tileset/parallax. Moon campaign now chains moon03 -> mars01 -> mars02 -> victory. Also fix review findings: deterministic seed on generated level restart, NULL checks on calloc in spawn functions, charge timeout to prevent infinite charge on flat terrain, and stop suppressing stderr in Makefile web-serve target so real errors are visible.

# 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)~~ ✓
|
||
Audited and fixed all engine bottlenecks for maps up to 8192x8192:
|
||
- `MAX_MAP_SIZE` constant (8192) replaces hard-coded 4096 caps in tilemap
|
||
loader and editor resize. Tile layers allocate fine at 5000x5000 (~143 MB).
|
||
- Dynamic line reader in `tilemap_load()` replaces fixed 16 KB `fgets` buffer;
|
||
handles arbitrarily long tile rows without truncation.
|
||
- `MAX_ENTITY_SPAWNS` raised from 128 to 512; `MAX_EXIT_ZONES` from 8 to 16.
|
||
- Entity distance culling: `entity_update_all()` skips entities beyond 2×
|
||
screen width from the camera; `entity_render_all()` skips entities outside
|
||
the viewport + 64 px margin. Player, spacecraft, and drone use
|
||
`ENTITY_ALWAYS_UPDATE` flag to opt out of culling.
|
||
- Editor flood fill replaced with scanline algorithm — O(height) stack usage
|
||
instead of O(area), safe for very large maps.
|
||
- Verified: tilemap rendering already viewport-culled, physics queries are O(1)
|
||
local tile lookups, float precision fine up to ~1M pixels (62 K tiles).
|
||
|
||
## ~~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~~ ✓
|
||
Implemented: 3 moon levels connected by spacecraft takeoff/landing sequences.
|
||
- **moon01.lvl** (1000 tiles) — Exit triggers spacecraft, transitions to moon02.
|
||
- **moon02.lvl** (200 tiles) — Crater fields, tighter platforming. Spacecraft
|
||
intro, 7 asteroids, unarmed. Exit to moon03.
|
||
- **moon03.lvl** (150 tiles) — Dark side, hardest moon terrain. Spacecraft
|
||
intro, 5 asteroids, unarmed until gun powerup near exit. Exit to level01.
|
||
- **level01.lvl** — Space station with spacecraft landing intro (arriving from moon).
|
||
|
||
## ~~Level generator: height zones (verticality)~~ ✓
|
||
Implemented: tall level support (46 tiles, two screens) with height zones.
|
||
- Camera vertical look-ahead (30px lead when player moves vertically > 50 px/s)
|
||
- All segment generators (`gen_flat`, `gen_pit`, `gen_platforms`, `gen_corridor`,
|
||
`gen_arena`, `gen_shaft`, `gen_transition`) accept `ground_row` parameter —
|
||
platforms, enemies, and hazards are placed relative to the zone's ground level
|
||
- `SEG_CLIMB` connector segment type: vertical shaft with alternating platforms,
|
||
wall openings, optional moving platform and enemies, bridges height zones
|
||
- `levelgen_generate()` assigns zones per theme: Surface → LOW (row 43),
|
||
Base → HIGH (row 17), Station → alternates. `SEG_CLIMB` auto-inserted at
|
||
zone boundaries. Single-theme levels stay at standard 23-tile height.
|
||
- Station generator unchanged (23 tiles, corridor envelope constrains)
|
||
- Tall test level: `assets/levels/tall_test.lvl` (40x46)
|
||
|
||
## ~~Jetpack boost blue flame effects~~ ✓
|
||
Implemented: `particle_emit_jetpack_boost_burst()` (electric blue core +
|
||
blue-white flare, 18 particles mixed into regular burst) and
|
||
`particle_emit_jetpack_boost_trail()` (blue sparks + pale blue wisps,
|
||
3 particles/frame). Both activate only when `jetpack_boost_timer > 0`.
|
||
Burst fires on dash start, trail emits each frame during dash.
|
||
|
||
## ~~Pause menu~~ ✓
|
||
Implemented: extracted bitmap font from `editor.c` into shared `engine/font`
|
||
module (`font.h`/`font.c`). Added `MODE_PAUSED` game state to `main.c` with
|
||
semi-transparent overlay, menu items (Resume / Restart / Quit), up/down
|
||
navigation, confirm with jump/enter. Restart reloads file-based levels or
|
||
regenerates procedural levels.
|
||
|
||
## ~~Laser turret hazard~~ ✓
|
||
Implemented: `ENT_LASER_TURRET` entity with state machine (IDLE → CHARGING →
|
||
FIRING → COOLDOWN). Beam uses per-pixel raycast via `tilemap_is_solid()`.
|
||
Player damage via point-to-line distance check. Rendering with
|
||
`SDL_RenderDrawLine` and perpendicular offset for beam thickness.
|
||
Two variants: `laser_turret` (fixed, aims left) and `laser_turret_track`
|
||
(rotates toward player at 1.5 rad/s during idle/charge, locks on fire).
|
||
Both registered in entity registry with editor icons.
|
||
|
||
## ~~New enemies: Charger and Spawner~~ ✓
|
||
Implemented in `enemy.h`/`enemy.c`:
|
||
- **Charger** — Ground patrol → ALERT (0.5 s telegraph) → CHARGE (150 px/s
|
||
rush) → STUNNED (0.8 s on wall hit, reverses). 2 HP. Detects player in
|
||
horizontal line-of-sight within 200 px.
|
||
- **Spawner** — Stationary. Spawns grunts every 4.5 s (max 3 alive via
|
||
`count_alive_grunts()`). Pulses before spawn. 3 HP, destructible. Purple
|
||
color scheme. Both registered in entity registry with editor icons.
|
||
|
||
## ~~Mars campaign~~ ✓
|
||
Implemented: two handcrafted levels plus procedural generator support.
|
||
- **mars01.lvl** (250×23, Mars Surface): low gravity (370), wind, wide-open
|
||
red terrain, charger + grunt enemies, spacecraft intro. New
|
||
`mars_tileset.png` and `PARALLAX_STYLE_MARS` (salmon sky, red mesas, dust).
|
||
- **mars02.lvl** (40×46, Mars Base): normal gravity (700), tall vertical
|
||
corridors with narrow passages, turrets, laser turrets (fixed + tracking),
|
||
spawners, chargers, grunts. Victory exit at bottom.
|
||
- Generator: `THEME_MARS_SURFACE` / `THEME_MARS_BASE` with per-theme gravity,
|
||
bg color, parallax style, tileset path, segment probabilities, and height
|
||
zone assignment. Mars themes added to procedural progression (6 options).
|
||
- Moon campaign now chains to Mars: moon03 → mars01 → mars02 → victory.
