Shadowcasting for FOV

Roguelike toolkit (pathfinding, FOV, map generation, scheduling) for @vampgg.

Engine-agnostic rectangular and hex grid vision with field-of-view, reciprocal line-of-sight, visibility-cost policy and persistent fog-of-war state.

Yendor is a roguelike library, meant to perform much of the heavy lifting when creating roguelike games. It takes inspiration from [rot-js](https://ondras.github.io/rot.js/hp), as well as [bracket-lib](https://github.com/thebracket/bracket-lib). ROT still

Engine-agnostic 2D vision core: line-of-sight, field-of-view cones, and visibility-polygon (shadow-casting) computation against segment/rect/polygon obstacles. The gameplay-level visibility layer Cocos (and most engines) don't ship — stealth detection, AI
