Cinder Hammer
An independent boss mod for Iron Coast mission 5, Cinder Docks. The furnace gunship patrols persistently at the top of the combat area. A pressure-warning sound precedes three molten projectiles fired six simulation ticks apart. The center mortar travels vertically; the two plasma rounds spread outward.
- Enemy:
iron_coast_boss_5:unit; health 160, reward 1,800, logical size 96×64. - Mortar and plasma: damage 3, speed 4; a 54-tick attack cycle.
- Death objective:
iron_coast_boss_5:defeated, incremented only on actual death. - Manifest API 1, package version 1.0.0, no dependencies or overrides.
The package never completes a mission itself. A mission must spawn the enemy, declare this package as a dependency, and require its death objective. Each enemy instance stores its own attack clock and patrol direction in serializable Rhai state. Dead or removed enemies cannot issue attacks or movement commands.
SD PNGs are derived from the same transparent generated masters as the 8× HD
PNGs. Both modes retain the same logical canvas and collision dimensions.

The generation prompts are in prompts/; provenance.json records tool mode
and source hashes. All artwork and audio belong in Git with this mod.
Run python3 build_assets.py to reproduce the resized art and synthesized mono
22,050 Hz, 16-bit PCM warning, shot and destruction sounds. Python and Pillow
are required. audio-recipe.json and art-qa.json record file hashes and checks.
Run cargo test --locked --manifest-path validation/Cargo.toml from this folder
for five asset-independent checks of attack timing, multiple-instance state,
save serialization, dead-entity guards, patrol turns, actual simulation
persistence, rewards and the single death objective. The simulation test also
validates the real package-local PNGs and WAVs.
