Constructor Details

#initialize(world, parent, pin_tra, group = nil) ⇒ Motor

Create a motor joint.

Parameters:

  • world (MSPhysics::World)
  • parent (MSPhysics::Body, nil)
  • pin_tra (Geom::Transformation, Array<Numeric>) —

    Pin transformation in global space. Matrix origin is interpreted as the pin position. Matrix Z-axis is interpreted as the pin direction.

  • group (Sketchup::Group, Sketchup::ComponentInstance, nil) (defaults to: nil)

Instance Method Details

#accel ⇒ Numeric

Note:

The actual acceleration is accel * controller.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Get rotational acceleration in radians per second per second.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#accel=(value) ⇒ Object

Note:

The actual acceleration is accel * controller.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Set rotational acceleration in radians per second per second.

Parameters:

  • value (Numeric)

Since:

  • 1.0.0

#controller ⇒ Numeric

Note:

The actual acceleration is accel * controller.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Get motor controller, magnitude and direction of the desired acceleration.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#controller=(value) ⇒ Object

Note:

The actual acceleration is accel * controller.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Set motor controller, magnitude and direction of the desired acceleration.

Parameters:

  • value (Numeric)

Since:

  • 1.0.0

#cur_alpha ⇒ Numeric

Get current angular acceleration in radians per second per second.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#cur_angle ⇒ Numeric

Get current angle in radians.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#cur_omega ⇒ Numeric

Get current angular velocity in radians per second.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#damp ⇒ Numeric

Note:

Higher damper makes rotation stronger.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Get rotational damper.

Returns:

  • (Numeric)

Since:

  • 1.0.0

#damp=(value) ⇒ Object

Note:

Higher damper makes rotation stronger.

Note:

The maximum angular rate in radians per second is accel * controller / damp.

Set rotational damper.

Parameters:

  • value (Numeric) —

    A value greater than or equal to zero.

Since:

  • 1.0.0

#free_rotate_enabled=(state) ⇒ Object

Enable/disable free rotate. Free rotate allows the motor to spin freely when accel is zero.

Parameters:

  • state (Boolean)

Since:

  • 1.0.0

#free_rotate_enabled? ⇒ Boolean

Determine whether free rotate is enabled. Free rotate allows the motor to spin freely when accel is zero.

Returns:

  • (Boolean)

Since:

  • 1.0.0
