void ForceEarlyOut ()
 Force the collision detection algorithm to terminate as soon as possible. Call this from the AddHit function when a satisfying hit is found. More...
 
bool ShouldEarlyOut () const
 When true, the collector will no longer accept any additional hits and the collision detection routine should early out as soon as possible. More...
 
float GetEarlyOutFraction () const
 Get the current early out value. More...
 
float GetPositiveEarlyOutFraction () const
 Get the current early out value but make sure it's bigger than zero, this is used for shape casting as negative values are used for penetration. More...

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 >.
