Brings in scripted flight paths for special stage enemies (GAL-40) on top of the high-score persistence work (GAL-56) already on main. Conflict resolution: - src/game_state.rs, src/systems.rs: kept HEAD's imports — they are a superset that includes HighScore/persistence; the incoming branch's changes were just import-formatting that HEAD had already adopted. - src/resources.rs: kept both — HEAD's HighScore resource and the incoming flight_patterns test module are independent additions. |

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 cargo build
How to Test
nix develop --command cargo test
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 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):
nix develop --command cargo build
nix run .#take-screenshots -- ./target/debug/bglga 3 6 1 ./shots
