Member Function Documentation

◆ apply_control()

bool MovingPartMatrix::apply_control ( PandaNode node)
virtual

Specifies a node to influence this particular joint so that it will always hold the node's transform.

Returns true if this is a joint that can be so controlled, false otherwise. This is called internally by PartBundle::control_joint().

Reimplemented from PartGroup.

Definition at line 380 of file movingPartMatrix.cxx.

References AnimChannelMatrixDynamic::set_value_node.

◆ apply_freeze_matrix()

bool MovingPartMatrix::apply_freeze_matrix ( const LVecBase3 &  pos,
const LVecBase3 &  hpr,
const LVecBase3 &  scale 
)
virtual

Freezes this particular joint so that it will always hold the specified transform.

Returns true if this is a joint that can be so frozen, false otherwise. This is called internally by PartBundle::freeze_joint().

Reimplemented from PartGroup.

Definition at line 368 of file movingPartMatrix.cxx.

◆ get_blend_value()

void MovingPartMatrix::get_blend_value ( const PartBundle root)
virtual

Attempts to blend the various matrix values indicated, and sets the _value member to the resulting matrix.

Implements MovingPartBase.

Definition at line 52 of file movingPartMatrix.cxx.

◆ make_default_channel()

AnimChannelBase * MovingPartMatrix::make_default_channel ( ) const
virtual

Creates and returns a new AnimChannel that is not part of any hierarchy, but that returns the default value associated with this part.

◆ make_MovingPartMatrix()

TypedWritable * MovingPartMatrix::make_MovingPartMatrix ( const FactoryParams params)
static
