Detailed Description

This is the base class of both EggJointData and EggSliderData.

It represents a single component of a character, either a joint or a slider, along with back pointers to the references to this component in all model and animation egg files read.

Member Function Documentation

◆ add_name()

void EggComponentData::add_name ( const std::string &  name,
NameUniquifier uniquifier 
)

Adds the indicated name to the set of names that this component can be identified with.

If this is the first name added, it becomes the primary name of the component; later names added do not replace the primary name, but do get added to the list of names that will be accepted by matched_name().

Definition at line 56 of file eggComponentData.cxx.

References NameUniquifier::add_name(), and Namable::has_name().

◆ extend_to()

void EggComponentData::extend_to ( int  model_index,
int  num_frames 
) const

Extends the number of frames in the indicated model (presumably an animation table model) to the given number.

Definition at line 99 of file eggComponentData.cxx.

References get_model().

Referenced by EggCharacterData::check_num_frames().

◆ get_frame_rate()

double EggComponentData::get_frame_rate ( int  model_index) const

Returns the number of frames of animation for this particular component in the indicated model.

Definition at line 110 of file eggComponentData.cxx.

References EggBackPointer::get_frame_rate(), and get_model().

Referenced by EggCharacterData::get_frame_rate().

◆ get_model()

EggBackPointer * EggComponentData::get_model ( int  model_index) const
inline

Returns the back pointer to an egg file for the indicated model if it exists, or NULL if it does not.

◆ get_num_frames()

int EggComponentData::get_num_frames ( int  model_index) const

Returns the number of frames of animation for this particular component in the indicated model.

Definition at line 86 of file eggComponentData.cxx.

References get_model().

Referenced by EggCharacterData::check_num_frames(), and EggCharacterData::get_num_frames().

◆ get_num_models()

int EggComponentData::get_num_models ( ) const
inline

Returns the maximum number of back pointers this component may have.

The component may store a back pointer for models indexed 0 .. num_models - 1. You must call has_model() on each model index to confirm whether a particular model in that range has a back pointer.

Definition at line 21 of file eggComponentData.I.

◆ has_model()

bool EggComponentData::has_model ( int  model_index) const
inline

Returns true if the component has a back pointer to an egg file somewhere for the indicated model, false otherwise.

Definition at line 30 of file eggComponentData.I.

◆ matches_name()

bool EggComponentData::matches_name ( const std::string &  name) const

Returns true if the indicated name matches any name that was ever matched with this particular joint, false otherwise.

Definition at line 74 of file eggComponentData.cxx.

◆ set_model()

void EggComponentData::set_model ( int  model_index,
EggBackPointer back 
)

Sets the back_pointer associated with the given model_index.
