const char * class_name - Name of the class for which derived classes are to be found.
Vector<String> & OUT_out_classes - Output buffer for the list of classes derived from the specified class.
Notice
This output buffer is to be filled by the Engine as a result of executing the method.

Return value

Number of derived classes.

int getClassParameters ( const char * class_name, Vector<int> & OUT_out_parameters ) const#

Obtains the list of all animation parameter for the specified class and puts it to the specified output buffer.

Arguments

const char * class_name - Name of the class for which the list of animation parameters is to be found.
Vector<int> & OUT_out_parameters - Output buffer for the list of parameters of the specified class.
Notice
This output buffer is to be filled by the Engine as a result of executing the method.

Return value

Number of animation parameters for the specified class.

const char * getParameterName ( AnimParams::PARAM param ) const#

Returns the name of the specified the specified animation parameter.

Arguments

AnimParams::PARAM param - Animation parameter.

Return value

Animation parameter name.

AnimationModifier::TYPE getParameterModifierType ( AnimParams::PARAM param ) const#

Returns the type of modifier used for the specified animation parameter.

Arguments

AnimParams::PARAM param - Animation parameter.

Return value

Modifier type for the specified parameter.

AnimParams::PARAM getParameterByName ( const char * param_name ) const#

Returns an animation parameter by its name.

Arguments

const char * param_name - Animation parameter name.

Return value

Animation parameter with the specified name.

void convertToUanims ( const char * folder_path, const Vector<String> & playbacks ) #

Converts all track-files in the old Tracker format ( .track) from the specfied folder to the new animation formats (.utrack / .uplay).

Arguments

const char * folder_path - Path to the folder containing track-files in the old Tracker format ( .track) to be converted to the new track format (.utrack).
const Vector<String> & playbacks - List of Tracker animation tracks in old format ( .track) to be converted to the new playback format(.uplay).

void convertToUanims ( const Vector<String> & tracks, const Vector<String> & playbacks ) #

Converts the specified lists of tracks in the old Tracker format ( .track) to the new animation formats (.utrack / .uplay).

Arguments

const Vector<String> & tracks - List of Tracker animation tracks in old format ( .track) to be converted to the new track format (.utrack).
const Vector<String> & playbacks - List of Tracker animation tracks in old format ( .track) to be converted to the new playback format(.uplay).

void checkUtrackTypes ( ) #

Checks all old-style animation parameter types (used in the Tracker tool) versus their equivalents in the new Animation System and outputs them to the console. In case of unknown parameter types the corresponding message is displayed.

bool animToBonesModifier ( const char * anim_path, const Ptr<AnimationModifierBones> & out_modifier, float duration ) const#

Converts the specified mesh animation file (.anim) to a modifier for ObjectMeshSkinned bones ( AnimationModifierBones) and puts it to the specified AnimationModifierBones instance.

Arguments

const char * anim_path - Math to the mesh animation file (.anim) to be converted.
const Ptr<AnimationModifierBones> & out_modifier - Resulting animation modifier.
float duration - Target animation duration, in seconds.

Return value

true if the specified mesh animation file was successfully converted; otherwise, false.
