Net -311 lines (1075 → 764). Build clean, clippy clean, 8 tests pass, headless render verified. Highlights: - player.rs: bug fix in handle_captured_player — was cloning captured.timer and ticking the clone, never the real timer. Consolidated kill_player as pub(crate) helper (was duplicated across 3 sites). Switched from ParamSet to two disjoint Queries. - enemy.rs: extracted step_attacker(), spawn_beam_visual(), end_beam(), pick_pattern() helpers — move_enemies is no longer 3-deep nested matches, beam cleanup no longer duplicated. Fixed SwoopDive overshoot check (was using already-applied movement). Mid-file `use` hoisted to top. - resources.rs: added StageConfigurations::for_stage() helper (was repeated 4×); FormationState/Score/CurrentStage now Default; extracted circle_formation() helper. - stage.rs: replaced raw world: &mut World access with ordinary ResMut system params (no need — resource types are disjoint). - game_state.rs: cleanup queries collapsed via Or<…> filters; dropped dead RestartMessage cleanup from cleanup_game_entities; button colors extracted as constants. - bullet.rs: reuses kill_player; introduced GRUNT_POINTS/BOSS_POINTS with TODO referencing GAL-27. - lib.rs: init_resource::<T>() for Default-implementing resources. - Removed unused TRACTOR_BEAM_COLOR constant. - Replaced per-frame println! debug spam with targeted info!/warn!. - Stripped noise comments that restated what the code does.

bglga
This project is a simple Galaga-like space shooter game built using the Bevy engine.
Current State
The game features:
- A player ship at the bottom of the screen that can move left and right.
- Shooting bullets upward using the spacebar or up arrow key.
- Enemy ships that spawn at the top and move downward.
- Collision detection between bullets and enemies.
- Collision detection between the player and enemies.
- A player lives system (starting with 3 lives).
- Player destruction upon collision.
- Player respawn after a short delay with temporary invincibility.
- Remaining lives displayed in the window title.
Controls
- Move Left: A key or Left Arrow
- Move Right: D key or Right Arrow
- Shoot: Spacebar or Up Arrow
How to Compile
nix develop --command bash -c "cargo build"
How to Run
- Make sure you have Rust and Nix installed.
- Clone the repository.
- Navigate to the project directory.
- Run the game using the command:
nix develop --command bash -c "cargo run"
Headless Screenshots
The flake exposes a take-screenshots app that launches a binary inside an
Xvfb display backed by lavapipe (software Vulkan), waits, and captures one or
more PNG screenshots. Useful for smoke-testing rendering without a real GPU.
nix run .#take-screenshots -- EXE NUM DELAY_START PAUSE_INBETWEEN [OUTPUT_DIR]
EXE— path to the executable to launchNUM— number of screenshots to takeDELAY_START— seconds to wait after launch before the first shotPAUSE_INBETWEEN— seconds between consecutive shotsOUTPUT_DIR— where to writeshot-NNN.pngfiles (default: current directory)
Example, capturing three frames of the game one second apart after a six-second warm-up (Bevy + software Vulkan needs roughly that long to render its first frame):
cargo build
nix run .#take-screenshots -- ./target/debug/bglga 3 6 1 ./shots
