Detailed Description

A special kind of CollisionHandler that does nothing except remember the CollisionEntries detected the last pass.

This set of CollisionEntries may then be queried by the calling function. It's primarily useful when a simple intersection test is being made, e.g. for picking from the window.

Member Function Documentation

◆ add_entry()

void CollisionHandlerQueue::add_entry ( CollisionEntry * entry )

virtual

Called between a begin_group() .

. end_group() sequence for each collision that is detected.

Reimplemented from CollisionHandler.

Definition at line 65 of file collisionHandlerQueue.cxx.

◆ begin_group()

void CollisionHandlerQueue::begin_group ( )

virtual

Will be called by the CollisionTraverser before a new traversal is begun.

It instructs the handler to reset itself in preparation for a number of CollisionEntries to be sent.

Reimplemented from CollisionHandler.

Definition at line 56 of file collisionHandlerQueue.cxx.

◆ clear_entries()

void CollisionHandlerQueue::clear_entries ( )

Removes all the entries from the queue.

Definition at line 109 of file collisionHandlerQueue.cxx.

◆ sort_entries()

void CollisionHandlerQueue::sort_entries ( )

Sorts all the detected collisions front-to-back by from_intersection_point() so that those intersection points closest to the collider's origin (e.g., the center of the CollisionSphere, or the point_a of a CollisionSegment) appear first.

Definition at line 77 of file collisionHandlerQueue.cxx.

Member Data Documentation

◆ get_entry

CollisionEntry * CollisionHandlerQueue::get_entry

Returns the nth CollisionEntry detected last pass.

Definition at line 42 of file collisionHandlerQueue.h.

◆ get_num_entries

int CollisionHandlerQueue::get_num_entries

Returns the number of CollisionEntries detected last pass.
