Constructor Detail

Asteroid

public Asteroid(double m,
                Point2 p,
                double t)

Creates an asteroid with the mass m at the position p heading at the direction of the angle t. The created asteroid uses the initial velocity and acceleration defined in the parameters asteroidInitialVelocity and asteroidInitialAcceleration. The angle is in radians.

Method Detail

isColliding

public boolean isColliding(Body other)

Returns whether the asteroid collides with the body other. When an asteroid hits a projectile, the asteroid is split. The parameter collisionAsteroidAsteroid defines, whether the asteroids can collide with each other.

Overrides:

isColliding in class Body

See Also:

Projectile, split()

split

public void split()

Splits the asteroid. After the split, the original asteroid is removed from the universe and replaced with fractions defined by the parameters asteroidMinFractionOnSplit, asteroidMaxFractionOnSplit, and asteroidSumOfFractionsOnSplit. If the parameter decorations is true, a cloud of debris is created at the site of the split according to the parameters debrisOnCloud and debrisMaxVelocity.
