  • Method Details

    • get

      public float get(MotorParam param)
      Return the value of the specified parameter.
      Parameters:
      param - which parameter (not null)
      Returns:
      the parameter value

    • isDampingLimited

      public boolean isDampingLimited()
      Test whether the spring's damping is limited (native field: m_springDampingLimited).
      Returns:
      true if limited, otherwise false

    • isMotorEnabled

      public boolean isMotorEnabled()
      Test whether the motor is enabled (native field: m_enableMotor).
      Returns:
      true if enabled, otherwise false

    • isServoEnabled

      public boolean isServoEnabled()
      Test whether the servo is enabled (native field: m_servoMotor).
      Returns:
      true if enabled, otherwise false

    • isSpringEnabled

      public boolean isSpringEnabled()
      Test whether the spring is enabled (native field: m_enableSpring).
      Returns:
      true if enabled, otherwise false

    • isStiffnessLimited

      public boolean isStiffnessLimited()
      Test whether the spring's stiffness is limited (m_springStiffnessLimited).
      Returns:
      true if limited, otherwise false

    • set

      public void set(MotorParam param, float value)
      Alter the specified parameter.
      Parameters:
      param - which parameter (not null)
      value - the desired parameter value

    • setDampingLimited

      public void setDampingLimited(boolean limitDamping)
      Limit or unlimit the spring's damping (native field: m_springDampingLimited).
      Parameters:
      limitDamping - true→limit, false→don't limit (default=false)

    • setMotorEnabled

      public void setMotorEnabled(boolean enableFlag)
      Enable or disable this motor (native field: m_enableMotor).
      Parameters:
      enableFlag - true→enable, false→disable (default=false)

    • setServoEnabled

      public void setServoEnabled(boolean enableFlag)
      Enable or disable the servo (native field: m_servoMotor). This setting has no effect if the motor is disabled.
      Parameters:
      enableFlag - true→enable, false→disable (default=false)

    • setSpringEnabled

      public void setSpringEnabled(boolean enableFlag)
      Enable or disable the spring (native field: m_enableSpring).
      Parameters:
      enableFlag - true→enable, false→disable (default=false)
