ShadowEdge

namespace Griff.Runtime;

public struct ShadowEdge

One side of something that blocks light, in the world. Its outside is on the left going from A to B, so the sides of a shape go round it clockwise. Owner is what it belongs to: an entity (its colliders), or a Tilemap (the tile at Cell).

Properties

A

public Vector2 A { get; init; }

B

public Vector2 B { get; init; }

Cell

public ValueTuple<int, int> Cell { get; init; }

For a side of a tile, the tile’s cell (column, row) in the Tilemap that’s its Owner.

Outward

public Vector2 Outward { get; }

Which way the side faces: out of the shape it belongs to.

Owner

public object? Owner { get; init; }

Methods

Crosses

public bool Crosses(Vector2 from, Vector2 to)

True if the straight line from from to to crosses this side.

Deconstruct

public void Deconstruct(out Vector2 A, out Vector2 B, out object? Owner)

Equals

public override bool Equals(object obj)

Equals

public bool Equals(ShadowEdge other)

FacesAwayFrom

public bool FacesAwayFrom(Vector2 light)

True if the side faces away from light. Shadows start at these, so whatever casts them is lit on the side facing the light, and dark behind.

GetHashCode

public override int GetHashCode()

ToString

public override string ToString()
