# File 'lib/rubysketch/constraint.rb', line 345

def axis()
  @constraint__.axis&.toVector
end

#axis=(axis) ⇒ Vector, Array<Numeric>

Sets the axis to slide along for the suspension.

Parameters:

  • axis (Vector, Array<Numeric>) —

    direction in the target local space

Returns:

  • (Vector, Array<Numeric>) —

    axis

def axis=(axis)
  @constraint__.axis = RubySketch.unwrap__ axis
end

#motor ⇒ Numeric?

Returns the motor speed.

Returns:

  • (Numeric, nil) —

    angular velocity per second

def motor()
  speed = @constraint__.motor
  speed && fromDegrees__(speed)
end

#motor=(speed) ⇒ Numeric?

Sets the motor speed that spins the wheel.

Parameters:

  • speed (Numeric, nil) —

    angular velocity per second, radians or degrees depending on angleMode(). nil stops the motor

Returns:

  • (Numeric, nil) —

    speed

end

#range ⇒ Range?

Returns the range of the translation along the axis.

Returns:

  • (Range, nil) —

    translation range

def range()
  @constraint__.range
end

#range=(range) ⇒ Range, ...

Sets the range of the translation along the axis.

Parameters:

  • range (Range, Numeric, nil) —

    translation range in pixels

Returns:

  • (Range, Numeric, nil) —

    range
