Detailed Description

Interface for modifying a mutable CompoundShape.

Mutable CompoundShapes trade some query performance for the ability to be modified after cooking. The builder applies modifications directly to the provided CookedShape, holding a strong reference to it. Modification is only supported for untransformed shapes (cooking must be done with identity position, rotation, and scale).

uint32_t

userData

)

const -> SubShapeIndex

Get the index of the SubShape with userData.

Note

Requires each SubShape to have unique user data.
