Method list

class ALMotionProxy
void ALMotionProxy::setIdlePostureEnabled(const std::string& pChainName, const bool& pEnable)

Starts or stops idle posture control on a chain.

Parameters:
  • pChainName – The chain name {“Body”, “Legs”, “Arms”, “LArm”, “RArm” or “Head”}.
  • pEnable – Activate or deactivate idle posture control on the desired Chain.
bool ALMotionProxy::getIdlePostureEnabled(const std::string& pChainName)

Gets the status of idle posture control on a chain.

Parameters:
  • pChainName – The chain name {“Body”, “Legs”, “Arms”, “LArm”, “RArm” or “Head”}.
Returns:

true if idle posture control is active on the chain, false otherwise.
void ALMotionProxy::setBreathEnabled(const std::string& pChainName, const bool& pEnable)

Starts or stops breathing animation on a chain.

Parameters:
  • pChainName – The chain name {“Body”, “Legs”, “Arms”, “LArm”, “RArm” or “Head”}.
  • pEnable – Activate or deactivate breathing animation on the desired Chain.
bool ALMotionProxy::getBreathEnabled(const std::string& pChainName)

Gets the status of breathing animation on a chain.

Parameters:
  • pChainName – The chain name {“Body”, “Legs”, “Arms”, “LArm”, “RArm” or “Head”}.
Returns:

true if breathing is started on the chain, false otherwise.
void ALMotionProxy::setBreathConfig(const AL::ALValue& pConfig)

Configures the breathing animation.

Parameters:
  • pConfig – An ALValue of the form [["Bpm", pBpm], ["Amplitude", pAmplitude]]. pBpm is a float between 5 and 30 setting the breathing frequency in beats per minute. pAmplitude is a float between 0 and 1 setting the amplitude of the breathing animation. At high frequencies, only low amplitudes are allowed. Input amplitude may be clipped.

AL::ALValue ALMotionProxy::getBreathConfig()

This function gets the current breathing configuration.

Returns:An ALValue of the form [["Bpm", bpm], ["Amplitude", amplitude]]. bpm is the breathing frequency in beats per minute. amplitude is the normalized amplitude of the breathing animation, between 0 and 1.
