Detailed Description

Result of a shape cast test.

Constructor & Destructor Documentation

ShapeCastResult() [1/2]

JPH_OVERRIDE_NEW_DELETE ShapeCastResult::ShapeCastResult ( )

default

Default constructor.

ShapeCastResult() [2/2]

ShapeCastResult::ShapeCastResult ( float  inFraction, Vec3Arg  inContactPoint1, Vec3Arg  inContactPoint2, Vec3Arg  inContactNormalOrPenetrationDepth, bool  inBackFaceHit, const SubShapeID &  inSubShapeID1, const SubShapeID &  inSubShapeID2, const BodyID &  inBodyID2  )

inline

Constructor

Parameters

inFraction	Fraction at which the cast hit
inContactPoint1	Contact point on shape 1
inContactPoint2	Contact point on shape 2
inContactNormalOrPenetrationDepth	Contact normal pointing from shape 1 to 2 or penetration depth vector when the objects are penetrating (also from 1 to 2)
inBackFaceHit	If this hit was a back face hit
inSubShapeID1	Sub shape id for shape 1
inSubShapeID2	Sub shape id for shape 2
inBodyID2	BodyID that was hit

Member Function Documentation

GetEarlyOutFraction()

float ShapeCastResult::GetEarlyOutFraction ( ) const

inline

Function required by the CollisionCollector. A smaller fraction is considered to be a 'better hit'. For rays/cast shapes we can just use the collision fraction. The fraction and penetration depth are combined in such a way that deeper hits at fraction 0 go first.

Reversed()

ShapeCastResult ShapeCastResult::Reversed ( Vec3Arg  inWorldSpaceCastDirection ) const

inline

Reverses the hit result, swapping contact point 1 with contact point 2 etc.

Parameters

inWorldSpaceCastDirection

Direction of the shape cast in world space

Member Data Documentation

mFraction

float ShapeCastResult::mFraction

This is the fraction where the shape hit the other shape: CenterOfMassOnHit = Start + value * (End - Start)

mIsBackFaceHit

bool ShapeCastResult::mIsBackFaceHit

True if the shape was hit from the back side.
