Here’s a content guide to help you understand and complete the exercise on CodeHS.

function moveShip(e) key == "ArrowLeft") newX -= MOVE_STEP; else if (key == "Right" MOVE_STEP = 15 def on_key_press(key): global ship_x if key == "left": ship_x -= MOVE_STEP elif key == "right": ship_x += MOVE_STEP

function start() ship = new Rectangle(40, 20); ship.setPosition(getWidth()/2, getHeight() - 50); ship.setColor("gray"); add(ship);

// Add keyboard listener onKeyDown(moveShip);

# Boundaries if ship_x < 0: ship_x = 0 elif ship_x + ship_width > get_width(): ship_x = get_width() - ship_width
