In this project, we developed a multi-player computer game intended to help students address three common projectile physics misconceptions. The misconceptions are:

  • The greater the angle of elevation, the greater the distance travelled by a projectile
  • Projectiles on their ascending trajectory are increasing speed and vice versa
  • If one object is dropped from an elevated point and another is projected forward from the same point, then the projected object will take longer to reach the ground

The game supports two teams of players, the Red Team and the Blue Team, with a maximum number of six players in each team. Controlling either a helicopter or a tank, players must collaborate to destroy the command base of the opposing team.

This project was embarked on with the primary goal of developing the research team's technical capacity in game design and development for serious games.
