Class RangeShape

Namespace

TDMaker.Unity.Authoring

Assembly

TDMaker.Unity.dll

The single source of the range ellipse used by every view, gizmo and editor preview. It matches the simulation (Simulation.RangeDistanceSquared): a point is inside when dx²/r² + dy²/(k·r)² ≤ 1 (boundary included), with k = range Y scale. The horizontal semi-axis is r and the vertical semi-axis is k·r, so k < 1 flattens the ellipse vertically (an oblique top-down look).

Field Value

float

Methods

Contains(Vector2, Vector2, float, float)

Whether point lies inside (or on) the range ellipse around center.

public static bool Contains(Vector2 center, Vector2 point, float range, float yScale)

Parameters

center Vector2

point Vector2

range float

yScale float

Returns

bool

DistanceSquared(Vector2, Vector2, float)

Elliptical distance squared in horizontal units, equal to the simulation's range metric.

public static float DistanceSquared(Vector2 center, Vector2 point, float yScale)

Parameters

center Vector2

point Vector2

yScale float

Returns

float

Point(Vector2, float, float, float)

A point on the ellipse outline at angle radians.

public static Vector2 Point(Vector2 center, float range, float yScale, float angle)

Parameters

center Vector2

range float

yScale float

angle float

Returns

Vector2

SemiAxes(float, float)

Horizontal (x) and vertical (y) semi-axes of a range ellipse: (r, k·r).

public static Vector2 SemiAxes(float range, float yScale)

Parameters

range float

yScale float

Returns

Vector2

SpriteScale(float, float)

Local scale for a 1-unit sprite (circle or ring) so it covers the ellipse of radius range.

public static Vector3 SpriteScale(float range, float yScale)

Parameters

range float

yScale float

Returns

Vector3
