Without this hack projectiles are either pathethic or need a very high velocity to compensate. The resulting trajectory is a ballistic trajectory.īecause gravity is a harsh mistress literally every game ‘cheats’ this and fakes a much lower gravity constant for projectiles than is used for players. The games I play come with simple ballistic physics for projectile-based weapons: the projectiles are fired with an initial speed and are only affected by gravity.
