Collision class

Collision data.

### Contents

Contains information about collision between objects A and B, described by contact position, separation normal and separation distance.

If the collision occured, contact position is on object B surface, separation normal is *normalized* vector in which direction should object A be moved to separate the bodies, separation distance is positive and describes minimal movement of object A in direction of separation normal after which the contact position will no longer be colliding with object A.

If the collision not occured, contact position and separation normal is undefined (i.e., *not* normalized) and separation distance is negative or zero.

## Constructors, destructors, conversion operators

- Collision()
- Default constructor.
- Collision(const VectorTypeFor<dimensions, Float>& position, const VectorTypeFor<dimensions, Float>& separationNormal, Float separationDistance) explicit noexcept
- Constructor.
- operator bool() const
- Whether the collision happened.

## Public functions

- auto position() const -> VectorTypeFor<dimensions, Float>
- Collision position.
- auto separationNormal() const -> VectorTypeFor<dimensions, Float>
- Separation normal.
- auto separationDistance() const -> Float
- Separation distance.
- auto flipped() const -> Collision<dimensions>
- Flipped collision.

## Function documentation

###
template<UnsignedInt dimensions>
Magnum::Shapes::Collision<dimensions>:: Collision()

Default constructor.

Sets position, normal and separation distance to zero, as if no collision happened.

###
template<UnsignedInt dimensions>
Magnum::Shapes::Collision<dimensions>:: Collision(const VectorTypeFor<dimensions, Float>& position,
const VectorTypeFor<dimensions, Float>& separationNormal,
Float separationDistance) explicit noexcept

Constructor.

If separation distance is positive, the separation normal is expected to be normalized.

###
template<UnsignedInt dimensions>
Magnum::Shapes::Collision<dimensions>:: operator bool() const

Whether the collision happened.

Negative or zero separation distance means that no collision happened.

###
template<UnsignedInt dimensions>
VectorTypeFor<dimensions, Float> Magnum::Shapes::Collision<dimensions>:: separationNormal() const

Separation normal.

###
template<UnsignedInt dimensions>
Float Magnum::Shapes::Collision<dimensions>:: separationDistance() const

Separation distance.

###
template<UnsignedInt dimensions>
Collision<dimensions> Magnum::Shapes::Collision<dimensions>:: flipped() const

Flipped collision.

Returns new collision object as if the collision occured between flipped pair of objects, i.e. with flipped separation normal and contact position on surface of object A.
