Errata
At 10:50 in the video, there is a note saying that isEaten = IsColliding( ... ); would have also been a valid approach, but this is incorrect. With direct assignment, once the condition becomes false, the isEaten flag gets reset (which is not the desired behavior). With the if statement, once the flag is set it remains true regardless of what IsColliding( ... ) returns on subsequent frames.
