getX()

Category: Turtle

Gets the current x coordinate in pixels of the turtle.

The x coordinate is the distance from the turtle to the left of the screen.

Examples

var xLocation = getX();
console.log(xLocation);
moveTo(100, 100);
console.log(getX());

To the Right Move the turtle 50 pixels to the right.

// Move the turtle 50 pixels to the right.
var newX = getX() + 50;
moveTo(newX, 100);

Am I off the screen? Check whether the turtle has moved off the right side of the screen.

// Check whether the turtle has moved off the right side of the screen.
function isOffRight(){
  if (getX() > 320) {
    return true
  } else{
    return false
  }
}
turnRight(90); 
for(var i=0; i<10; i++){
  moveForward(50);
  console.log("Am I off the screen? "+ isOffRight());
}

Syntax

getX();

Parameters

getX() does not take any parameters.

Returns

Returns a number representing the current x coordinate in pixels of the turtle within the app display.

Tips

The screen default size is 320 pixels wide and 450 pixels high, but you can move the turtle off the screen by exceeding those dimensions.
The turtle can be moved off the screen so getX() can return a negative number if the turtle is off the screen to the left and getX() can return a number greater than 320 if the turtle is off the screen to the right.
