Detailed Description
An infinite line, similar to a CollisionRay, except that it extends in both directions.
It is, however, directional.
Definition at line 25 of file collisionLine.h.
Constructor & Destructor Documentation
◆ CollisionLine()
|
inline |
Creates an invalid line.
This isn't terribly useful; it's expected that the user will subsequently adjust the line via set_origin()/set_direction() or set_from_lens().
Definition at line 20 of file collisionLine.I.
Member Function Documentation
◆ register_with_read_factory()
|
static |
Tells the BamReader how to create objects of type CollisionLine.
Definition at line 101 of file collisionLine.cxx.
References BamReader::get_factory(), and Factory< Type >::register_factory().
Referenced by init_libcollide().
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from CollisionRay.
Definition at line 110 of file collisionLine.cxx.
