# ⚔️ Warbell **Defend the keep against nightly ork sieges.** A knight holds a central castle through wave after wave of night assaults across a five-biome island — real-time combat, an economy and upgrade tree, a town you build and defend, inventory and consumables, villagers, wildlife, and a bloodline succession loop. Built in Rust on [**Bevy 0.18**](https://bevyengine.org).

## Play - **Windows:** download [**`Warbell-Setup.msi`**](https://github.com/miskibin/warbell/releases/latest/download/Warbell-Setup.msi) and run it. The installer is self-signed, so Windows SmartScreen shows "Unknown Publisher" — click **More info → Run anyway**. - **From source** (any platform): see [Build from source](#build-from-source) below. | | | | |---|---|---| | ![Defend against the horde](site/screenshots/fight-orks.png) | ![Night combat](site/screenshots/night-combat.png) | ![The ork fortress](site/screenshots/ork-fortress.png) | | ![Snow biome](site/screenshots/snow-biome.png) | ![Desert biome](site/screenshots/desert-biome.png) | ![Swamp fortress](site/screenshots/swamp-fortress.png) | |

The first build is slow — `bevy` compiles at `opt-level = 3` even in dev so the scene isn't single-digit FPS — but incremental rebuilds of `src/` are fast. ## Architecture Two crates: - **`crates/core` (`tileworld_core`)** — pure, deterministic, zero-dependency game logic (`f64` throughout). Pathfinding (A*), the wave director, upgrade / buff / resource / inventory stores, ork & animal config, factions, RNG, the shop catalog. This is the unit-tested validation spec — `cargo test` runs it. No Bevy, no I/O, no rendering. - **`tileworld_bevy_forest` (root `src/`)** — the Bevy app: rendering, ECS systems, input, the scene. It imports `tileworld_core` for all the numbers/logic that must stay correct, wrapping core's stores as Resources (`PlayerRes`, `Bank`, `Inventory`, …). Each `src/.rs` is a self-contained `Plugin`; **`main.rs` is the assembly list** — read it as the table of contents. The whole world-sim is gated behind a freeze-gate state machine (`game_state.rs`): opening any panel or leaving `Playing` freezes the sim but keeps rendering. See **[`CLAUDE.md`](CLAUDE.md)** for the full conventions (coordinate frame, despawn-race rules, mesh-building contract, combat-number parity) and **`docs/superpowers/specs/`** for the per-subsystem roadmap and design docs. ## Screenshot harness The Bevy window can't be captured externally, so visuals are verified via a render-and-exit harness: ```bash # PowerShell $env:FOREST_SHOT="shot.png"; cargo run # bash FOREST_SHOT=shot.png cargo run ``` It renders ~90 frames so lighting/IBL settle, saves the PNG, and exits. Stage the shot with env vars read at startup: `FOREST_CAM` / `FOREST_TIME` (camera pose / time-of-day), `FOREST_BIOME` (boot into a biome), `FOREST_WAVE` / `FOREST_DEFEND=1` (stage a night siege), `FOREST_MENU=1` (start screen), `FOREST_PANEL=tree|inv|build` (open a UI panel), `FOREST_FP=1` (first-person), `FOREST_EQUIP="sword_gold,gold_armor"` (equip items on the hero). `BEVY_ASSET_ROOT` points at this dir if you run the binary from elsewhere. ## License Warbell's **source code** is **source-available** under the [PolyForm Noncommercial License 1.0.0](LICENSE) — read, build, run, modify, and share it for **non-commercial** purposes; commercial use is reserved.
