Virtual Basketball1.3

Virtual Basketball is a true-motion match simulator designed for learners with an interest in physics. It models ball movements under varying physical conditions. Virtual are a team's changing gravity and ball friction caused by e.g. wind. As in reality, the motion and result of each shot are computed according to the laws of gravity and friction. Two teams, Red-City Bulls and Blue-City Lakers, arecompeting against each other, attacking and defending.The defending team uses the Tab and Arrow keys of thekeyboard and changes its gravity vector and ball frictionwith Arrow_LEFT = ++40 units, Arrow_RIGHT = --40 units, Arrow_UP = ++1 unit, Arrow_DOWN = --1 unit,resulting in a different ball motion.The attacking team uses the mouse to shoot balls by: 1) pressing the left mouse button on the court marking the position of a player,2) keeping (!) the button down, moving to another position and releasing it giving the ball's speed and direction.As in reality, the motion and result of each shot arecomputed according to the laws of gravity and friction, and visually displayed on the computer screen.After one team has scored, its gravity vector and ballfriction are randomly changed (or manually by the other team)so that it becomes much harder to score again. This is theeasy way to play the game. The difficult way is to allowthe defending team to change its gravity and friction values all the time.Shareware registration ($ 5.00)
