Strategies and Motivations  Strategies Offense  Player tries to score a goal, avoid giving the puck away  Shots are automatically aimed at the center of the goalie Probability of puck going in is based on distance of the shot from the goal  Can’t aim up or down, shots will be flat Defense  Try to block shots and passes by getting in front of them  Hit people to take the puck away

Algorithm Style  Probability of scoring based on distance of shot from the goal The closer you are to the goal when you shoot, the more likely it is that you score a goal  Passing Game will locate the player closest to the player currently carrying the puck, and pass the puck to that player Switching players works the same way (switches to the closest player)  AI Offense will move into preprogrammed spots in the offensive zone when they have the puck. Spots are in the two face-off circles and between them in front of the net Defense works the same way  Lamothe’s Collision_BOBS() function will be used to detect collisions between blitter objects Player-player Player-puck Player-net  Rink will be static image  Goalie animations will be based on where the puck is Goalie moves out of the goal if the puck is far away  Puck physics are simplified Constant velocity, no friction  Sound playback based on Lamothe’s code Goal horn  When timer gets to 0, game will go into sudden-death overtime and will go on until a goal is scored
