Function: findCircleContact()

findCircleContact(vertices, normals, localCenter, faceIndex, separation, radius): CircleContact | null

Defined in: physics/collision/circle-polygon-contact.ts:129

Resolves the exact contact (face or vertex) between a circle and the polygon face found by findClosestFace, in the polygon's own local space.

Parameters​

vertices​

readonly Vector2[]

The polygon's vertices, in its own local space.

normals​

readonly Vector2[]

The polygon's outward-facing edge normals, matching vertices.

localCenter​

Vector2

The circle's center, in the polygon's local space.

faceIndex​

number

The closest face's index, from findClosestFace.

separation​

number

The closest face's separation, from findClosestFace.

radius​

number

The circle's radius.

Returns​

CircleContact | null

The resolved contact, or null if the shapes do not actually overlap (the circle's center lies beyond a vertex, out of radius).
