Detailed Description

Asteroid class. Asteroids are technically ships but do things a little differently. Constantly move forward at fixed speed, collisions impart some velocity change.

Constructor & Destructor Documentation

Asteroid::Asteroid	(	thor::ParticleSystem &	particleSystem,
		sf::Vector2f const &	position,
		sf::Vector2f const &	direction,
		float	spinSpeed = (rand() % 50 - 25) * 0.1f
	)

Parameters

position	Initial position of the Asteroid.
direction	The heading that the Asteroid will travel on
spinSpeed	How fast (in degrees per tick) that the asteroid will rotate

Member Function Documentation

void Asteroid::generateGeometry ( )

private

Generates a convex shape with a randomly generated number of sides and variations on the x and y position of each vertex.

Remarks

Uses Rcos(theta) to place points along a circle and then uses rand() vary the positions.

Generates a random shade of brown as fill color.

Though shape outline is thick, it is drawn inside the shape bounds (because it's negative).

Here is the call graph for this function:

Here is the caller graph for this function:

void Asteroid::onCollide ( Ship *  other )

overridevirtual

Colliding with ships will impart some of that ship's velocity on us.

Remarks

Asteroids do not "collide", with each other; they grind against and damage each other

Implements Ship.

Here is the call graph for this function:

void Asteroid::update ( )

overridevirtual

Moves us forward and keps us spinning.

Reimplemented from Ship.
