Detailed Description

Removes internal edges from collision results. Can be used to filter out 'ghost collisions'. Based on: Contact generation for meshes - Pierre Terdiman (https://www.codercorner.com/MeshContacts.pdf)

Constructor & Destructor Documentation

InternalEdgeRemovingCollector()

InternalEdgeRemovingCollector::InternalEdgeRemovingCollector ( CollideShapeCollector &  inChainedCollector )

inlineexplicit

Constructor, configures a collector to be called with all the results that do not hit internal edges.

Member Function Documentation

AddHit()

virtual void InternalEdgeRemovingCollector::AddHit ( const CollideShapeResult &  inResult )

inlineoverridevirtual

Flush()

void InternalEdgeRemovingCollector::Flush ( )

inline

After all hits have been added, call this function to process the delayed results.

OnBody()

virtual void InternalEdgeRemovingCollector::OnBody ( const Body &  inBody )

inlineoverridevirtual

When running a query through the NarrowPhaseQuery class, this will be called for every body that is potentially colliding. It allows collecting additional information needed by the collision collector implementation from the body under lock protection before AddHit is called (e.g. the user data pointer or the velocity of the body).

Reimplemented from CollisionCollector< ResultTypeArg, TraitsType >.

Reset()

virtual void InternalEdgeRemovingCollector::Reset ( )

inlineoverridevirtual

If you want to reuse this collector, call Reset()

Reimplemented from CollisionCollector< ResultTypeArg, TraitsType >.
