In the code example, pressing the spacebar causes the character to turn left by how many degrees?

• A. 5 degrees
• B. 15 degrees
• C. 20 degrees
• D. 10 degrees

Answer: (D)

Turning on a fixed input applies a rotation around the vertical axis, so each press of the spacebar nudges the character a little to the left. In this example, that nudge is ten degrees per press, meaning the heading decreases by 10 degrees each time space is pressed. This creates a controlled, noticeable turn without being too abrupt. If it were only five degrees, the turn would be subtler and might require multiple presses for the same effect; fifteen or twenty degrees would produce a larger, faster turn per press, changing the feel of the control. So ten degrees per press is the established, balanced amount used here.
