Member Function Documentation

bounceIfPossible() [1/2]

template<typename T >

vector< int > arkanoid::Ball::bounceIfPossible

(

vector< unique_ptr< T >> const &

entities

)

Checks for all Entity if there's a collision, if there is, then "bounce" off the Entity, i.e. rotate 90° in the right direction.

Parameters

entities

List of all the Entity of the World (Ball not included).

Returns

The indeces in the list of the Entity that the Ball collided with.

Definition at line 39 of file ball.cpp.

bounceIfPossible() [2/2]

void arkanoid::Ball::bounceIfPossible

(

unique_ptr< Player > const &

player

)

Checks if there's a collision with the Player, if there is, make the correct bounce (angle) depending on the point of collision.

Parameters

player

The Player of the World.

Definition at line 99 of file ball.cpp.

draw()

void arkanoid::Ball::draw ( ) const

virtual

Do nothing...

Implements arkanoid::Entity.

Definition at line 25 of file ball.cpp.

reset()

void arkanoid::Ball::reset ( )

virtual

Reset the direction of the Ball and set it at a specific position. (-> call this method when the Player missed the Ball).

Reimplemented in arkanoidSFML::BallSFML.

Definition at line 140 of file ball.cpp.

setInvisible()

void arkanoid::Ball::setInvisible

(

int

period

)

Make the Ball invisible for a period of time.

Parameters

period

The period the Ball becomes invisible (in frames).

Definition at line 34 of file ball.cpp.

speedUp()

void arkanoid::Ball::speedUp

(

double

factor

)

Change the velocity of the Ball by a factor.

Parameters

factor

The factor.

Definition at line 27 of file ball.cpp.

update()

void arkanoid::Ball::update ( )

virtual

Do nothing...

Implements arkanoid::Entity.
