Edge length.
Local-space normal vector (immutable Vec2).
Local-space projection along the edge normal.
First local vertex of this edge.
Second local vertex of this edge.
Parent polygon.
World-space normal vector (immutable Vec2). Requires polygon in a body.
World-space projection. Requires polygon in a body.
First world vertex. Requires polygon in a body.
Second world vertex. Requires polygon in a body.
An edge of a polygon shape.
Edges are read-only and managed by the polygon they belong to. Cannot be instantiated directly — only obtained from Polygon.edges.
Fully modernized — all getters access ZPP_Edge directly.
