bool unref ()
 Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

Detailed Description

Member Function Documentation

◆ __init__() [1/2]

__init__ ( const Physical  copy)

copy constructor (note- does deep copy of pn's) but does NOT attach itself to its template's physicsmanager.

◆ __init__() [2/2]

__init__ ( int  total_objects,
bool  pre_alloc 
)

Default Constructor.

The idea here is that most physicals will NOT be collections of sets (i.e. particle systems and whatever else). Because of this, the default constructor, unless otherwise specified, will automatically allocate and initialize one PhysicalObject. This makes it easier for high-level work.

pre-alloc is ONLY for multiple-object physicals, and if true, fills the physics_object vector with dead nodes, pre-allocating for the speed end of the speed-vs-overhead deal.

◆ addAngularForce()

addAngularForce ( AngularForce  f)
