Physical

class Physical

Bases: TypedReferenceCount

Defines a set of physically modeled attributes. If you want physics applied to your class, derive it from this.

explicit Physical(int total_objects = 1, bool pre_alloc = false)

Physical(Physical const &copy)

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.

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