Abstract: In view of the lack of quantitative calculation problems in the current basketball training, the
basketball training simulation system was developed. The exact solution of the best shot angle and
velocity of shots without air resistance is solved using the trajectory equation of basketball movement
whose start and end point are not in the same level. The result shows that the best shot angle will
increase with the increasement of the shot speed, decrease with the increasement of the shot height.
With the increasement of the shot distance, the minimum shot speed need to be increased, and the best
shot angle is decreased. At the same time, a visual simulation environment is created which includes the
animation of athletes, the basketballs with physical material, sound, level design, the best shot angle
calculation module and network scoring module. Players can use the visual environment to measure the
best shot angle and shot speed for auxiliary training.
