Detailed Description

A listener that gets notified when two Solids touch. These events get handled at the end of the time step, which is necessary because some physics engines cannot update objects in the middle of a time step (e.g. in the middle of collision detection).

Member Function Documentation

virtual OPAL_DECL void OPAL_CALL opal::CollisionEventHandler::handleCollisionEvent (  const CollisionEvent &  e  )  [pure virtual]

Called once for each pending CollisionEvent. This is always called at the end of every time step so CollisionEvents get handled right away. Referenced by internal_handlePendingCollisionEvents().

void opal::CollisionEventHandler::internal_handlePendingCollisionEvents (   )  [virtual]

Loops through the pending CollisionEvents, calling the event handling function (which is always user-defined) for each. Definition at line 47 of file CollisionEventHandler.cpp. References handleCollisionEvent(), and mPendingCollisionEvents.

void opal::CollisionEventHandler::internal_pushCollisionEvent (  const CollisionEvent &  e  )  [virtual]

Adds a CollisionEvent to this handler's internal list. These will get handled at the end of the current time step. Definition at line 41 of file CollisionEventHandler.cpp. References mPendingCollisionEvents. Referenced by opal::ode_hidden::internal_collisionCallback().

Member Data Documentation

std::vector<CollisionEvent> opal::CollisionEventHandler::mPendingCollisionEvents [protected]

This list holds pending CollisionEvents. It allows events to be queued during collision detection and handled at a safe time. Definition at line 101 of file CollisionEventHandler.h. Referenced by internal_handlePendingCollisionEvents(), internal_pushCollisionEvent(), and ~CollisionEventHandler().
