Buckland's Soccer Game

• Let's walk through the game as it's described in the book. We're not going to implement it as a lab, but feel free to use his code.
• He gives some classes and rules.
• He then splits the pitch into sections. Why?
• It's a reasonable way to divide the pitch so that players can more easily go to reasonable places.
• You could use more, or fewer squares, but his 18 seems a reasonable start.
• It might not be optimal, but it is a good approximation to say that the keeper stays in 1 if the ball is on his side of the pitch.
• Another approximation is modelling friction on the football by constant deceleration.
• He's using physics for movement, but friction is now modelled by a deceleration.
• This means you don't have to do the physics calculations for grass/ball friction.
• Buckland plugs and chugs to come up with time to cover distance (shall we look on page 142).
