Detailed Description

This is a morph slider within the character.

It's simply a single floating-point value that animates generally between 0 and 1, that controls the effects of one or more morphs within the character.

Member Function Documentation

◆ make_CharacterSlider()

TypedWritable * CharacterSlider::make_CharacterSlider ( const FactoryParams params)
static

Factory method to generate a CharacterSlider object.

Definition at line 88 of file characterSlider.cxx.

References parse_params().

Referenced by register_with_read_factory().

◆ make_copy()

PartGroup * CharacterSlider::make_copy ( ) const
virtual

Allocates and returns a new copy of the node.

Children are not copied, but see copy_subgraph().

Reimplemented from PartGroup.

Definition at line 60 of file characterSlider.cxx.

◆ register_with_read_factory()

void CharacterSlider::register_with_read_factory ( )
static

Factory method to generate a CharacterSlider object.

Definition at line 103 of file characterSlider.cxx.

References BamReader::get_factory(), make_CharacterSlider(), and Factory< Type >::register_factory().

Referenced by init_libchar().

◆ update_internals()

bool CharacterSlider::update_internals ( PartBundle root,
PartGroup parent,
bool  self_changed,
bool  parent_changed,
Thread current_thread 
)
virtual

This is called by do_update() whenever the part or some ancestor has changed values.

It is a hook for derived classes to update whatever cache they may have that depends on these.

The return value is true if the part has changed as a result of the update, or false otherwise.

Reimplemented from MovingPartBase.
