void parse_params(const FactoryParams ¶ms, DatagramIterator &scan, BamReader *&manager)
Takes in a FactoryParams, passed from a WritableFactory into any TypedWritable's make function,...
virtual void write_datagram(BamWriter *manager, Datagram &me)
Function to write the important information in the particular object to a Datagram.
A specialization on AnimChannel to add all the special matrix component operations.
virtual void write_datagram(BamWriter *manager, Datagram &dg)
Writes the contents of this object to the datagram for shipping out to a Bam file.
static void register_with_read_factory()
Tells the BamReader how to create objects of type AnimChannelMatrixFixed.
virtual void get_scale(int frame, LVecBase3 &scale)
Gets the scale value at the indicated frame.
virtual void get_shear(int frame, LVecBase3 &shear)
Returns the a, b, and c shear components associated with the current frame.
virtual void get_quat(int frame, LQuaternion &quat)
Returns the rotation component associated with the current frame, expressed as a quaternion.
virtual void get_pos(int frame, LVecBase3 &pos)
Returns the x, y, and z translation components associated with the current frame.
virtual void get_hpr(int frame, LVecBase3 &hpr)
Returns the h, p, and r components associated with the current frame.
virtual bool has_changed(int last_frame, double last_frac, int this_frame, double this_frac)
Returns true if the value has changed since the last call to has_changed().
virtual void output(std::ostream &out) const
Writes a one-line description of the group.
virtual void get_value_no_scale_shear(int frame, LMatrix4 &value)
Gets the value of the channel at the indicated frame, without any scale or shear information.
This template class is the parent class for all kinds of AnimChannels that return different values.
This is the base class for AnimChannel and AnimBundle.

void register_factory(TypeHandle handle, CreateFunc *func, void *user_data=nullptr)
Registers a new kind of thing the Factory will be able to create.
TypeHandle is the identifier used to differentiate C++ class types.
Base class for objects that can be written to and read from Bam files.
