Rust Tilemap Camera Rendering

Use this skill to build grid-based maps and camera-relative rendering in Rust. Keep map storage, coordinate conversion, movement validation, and draw order explicit before adding richer art or themes.

Core Workflow

1. Define map dimensions, tile types, and coordinate/index conversion.
2. Add bounds and walkability checks before player or entity movement.
3. Keep map generation behind a builder or constructor boundary.
4. Render visible tiles through a camera-relative coordinate transform.
5. Draw layers in deterministic order: base terrain, entities, effects, UI.
6. Add themes only after the map and camera rules are stable.
