RexBoard Visibility And Routes
Use this skill for board algorithms that answer visibility and route traversal questions.
Use This First
Choose the helper:
| Need | Use |
|---|
| Visible tiles around a chess piece | FieldOfView.findFOV(...) |
| Can a piece see a target | FieldOfView.isInLOS(...) or LOS(...) |
| Filter visible targets | FieldOfView.LOS(targets, ...) |
| Directional route traversal | Monopoly.getPath(...) |
| Route stop/blocker rules | Monopoly.costCallback |
Required Setup
This skill assumes pieces are already registered as RexBoard chess. If not, use rexboard-board-and-chess.

Core Rules
- Use
FieldOfView for visibility; use PathFinder for shortest/reachable paths.
- Use
Monopoly for directional route traversal, not general A* pathfinding.
- Keep occupied tests, blocker tests, pre-test callbacks, and cost callbacks separate.
- Use instance sentinels (
fov.BLOCKER, fov.INFINITY, monopoly.STOP, monopoly.BLOCKER) in callbacks.
- Choose
coneMode: 'direction' for grid-direction cones and coneMode: 'angle' for angular cones.

Gotchas
FieldOfView.BLOCKER is null; FieldOfView.INFINITY is undefined.Monopoly.STOP is -1; Monopoly.BLOCKER is null.LOS has several overloads; keep argument order explicit in generated code.
