Constructor Detail

RotationMotor

public RotationMotor(long nativeId)

Instantiate a motor. Used internally.

Parameters:

nativeId - the ID of a pre-existing btRotationalLimitMotor2 (not zero)

Method Detail

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)

setStiffnessLimited

public void setStiffnessLimited(boolean limitStiffness)

Limit or unlimit the spring's stiffness (native field: m_springStiffnessLimited).

Parameters:

limitStiffness - true→limit, false→don't limit (default=false)
