PhysicsShape

@Immutable

Shape descriptor used by the body registration API.

The shape describes the collision geometry that will be created for the body. The actual dimensions are derived from the composable's measured size unless explicitly provided by the shape implementation.

The public API exposes Box, Circle, and Polygon. Additional shapes can be added later without breaking source compatibility.

Types

Box

data object Box : PhysicsShape

Rectangle shape based on the composable bounds.

Circle

data class Circle(val radiusPx: Float? = null) : PhysicsShape

Circle shape.

Polygon

data class Polygon(val vertices: List<PhysicsVector2>, val space: PhysicsShape.Polygon.VertexSpace = VertexSpace.Normalized) : PhysicsShape

Convex polygon shape (Box2D/jbox2d-style).
