Constructor detail

LineSensor

()

constructor

public function LineSensor(x:Number, y:Number, size:Number = 5)

Creates a sensor with the given parameters.

NOTE: the shape of the sensing area of the line sensors such as QRD1114 is always a small square

Parameters

	`x:Number` — - x coordinate relative to the center of the robot

	`y:Number` — - y coordinate relative to the center of the robot

	`size:Number` (default = `5`) — - size of the sensor (5 by default)

Method detail

getReading

()

method

public override function getReading():void

Determine if the sensor is on the line and set the output port accordingly: HIGH if the sensor is on the line and LOW if the sensor is off the line.
