Constructor Detail

TranslationMotor

public TranslationMotor(long nativeId)

Instantiate a motor. Used internally.

Parameters:

nativeId - the ID of a pre-existing btTranslationalLimitMotor2 (not zero)

Method Detail

get

public Vector3f get(MotorParam param,
                    Vector3f storeResult)

Copy the specified parameter of this motor.

Parameters:

param - which parameter (not null)

storeResult - storage for the result (modified if not null)

Returns:

the parameter value for each axis (either storeResult or a new instance)

isDampingLimited

public boolean isDampingLimited(int axisIndex)

Test whether the indexed spring's damping is limited (m_springDampingLimited).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

Returns:

true if limited, otherwise false

isMotorEnabled

public boolean isMotorEnabled(int axisIndex)

Test whether the indexed motor is enabled (m_enableMotor).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

Returns:

true if enabled, otherwise false

isServoEnabled

public boolean isServoEnabled(int axisIndex)

Test whether the indexed servo is enabled (m_servoMotor).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

Returns:

true if enabled, otherwise false

isSpringEnabled

public boolean isSpringEnabled(int axisIndex)

Test whether the indexed spring is enabled (m_enableSpring).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

Returns:

true if enabled, otherwise false

isStiffnessLimited

public boolean isStiffnessLimited(int axisIndex)

Test whether the indexed spring's stiffness is limited (m_springStiffnessLimited).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

Returns:

true if limited, otherwise false

set

public void set(MotorParam param,
                Vector3f values)

Alter the specified parameter of this motor.

Parameters:

param - which parameter (not null)

values - the desired parameter value for each axis (not null, unaffected)

setDampingLimited

public void setDampingLimited(int axisIndex,
                              boolean limitDamping)

Limit or unlimit the damping of the indexed spring (m_springDampingLimited).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z

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

setMotorEnabled

public void setMotorEnabled(int axisIndex,
                            boolean enableFlag)

Enable or disable the indexed axis (m_enableMotor).

Parameters:

axisIndex - which axis: 0→X, 1→Y, 2→Z
