Constructor Detail

Projectile

public Projectile(Point2 p,
                  double t,
                  Ship s)

Creates a projectile at the position p heading at the direction of the angle t and launched by the ship s. The mass of the projectile is defined by the parameter projectileMass and the size by the parameter projectileRadius. The created projectile uses the initial velocity and acceleration defined in the parameters projectileInitialVelocity and projectileInitialAcceleration. The angle is in radians.
