Defines a single collision event.
The abstract interface to a number of classes that decide what to do when a collision is detected.
This class manages the traversal through the scene graph to detect collisions.
NodePath is the fundamental system for disambiguating instances, and also provides a higher-level int...

TypeHandle is the identifier used to differentiate C++ class types.
Definition: typeHandle.h:81
A base class for things which need to inherit from both TypedObject and from ReferenceCount.
