if (event.key == "ArrowRight") {

newX += 1

moved = true

}

if (event.key == "ArrowUp") {

newY -= 1

moved = true

}

if (event.key == "ArrowDown") {

newY += 1

moved = true

}

Instead of using this.cursor as in the previous samples, we’re now using the value of event.key to check if any cursor key was pressed. It is quite similar to the previous code, but since all that keyboard input handling logic is now contained in its own function, it becomes easier to maintain. // Execute movement

if (moved) {

this.movementPoints -= 1
