Detailed Description

Abstract base class for all ball types in the game.

This class defines the common interface and functionality for all types of balls in the game. It handles movement, collision detection, and score updates.

Constructor & Destructor Documentation

BallBase()

BallBase::BallBase

(

float

size = 35.0f

)

Constructor for BallBase.

Parameters

size	The size (diameter) of the ball, defaults to 15.0f

Initializes the ball at the center of the screen with a specified size and randomizes its initial direction

Parameters

size	The size (diameter) of the ball

~BallBase()

virtual BallBase::~BallBase ( )

virtual

Virtual destructor for proper cleanup in derived classes.

Member Function Documentation

boundaries()

virtual SDL_Rect BallBase::boundaries ( ) const

virtual

Gets the collision boundaries of the ball.

Returns a rectangle representing the ball's position and size for collision detection purposes.

Returns

SDL_Rect representing the ball's boundaries

get_color()

SDL_Color BallBase::get_color

(

)

const

Gets the color of the ball.

Returns

The ball's color as an SDL_Color structure

get_game_mode()

int BallBase::get_game_mode

(

)

const

get_pos_x()

float BallBase::get_pos_x

(

)

const

Gets the x-coordinate of the ball.

Returns

The ball's x position

get_pos_y()

float BallBase::get_pos_y

(

)

const

Gets the y-coordinate of the ball.

Returns

The ball's y position

get_vel_x()

float BallBase::get_vel_x

(

)

const

Gets the x-velocity component of the ball.

Returns

The ball's velocity along the x-axis

get_vel_y()

float BallBase::get_vel_y

(

)

const

Gets the y-velocity component of the ball.

Returns

The ball's velocity along the y-axis

random_direction_angle()

void BallBase::random_direction_angle

(

)

Randomizes the direction of the ball.

Changes the ball's velocity to move in a random direction

Sets the ball's velocity to move in a random direction with a random angle between -45 and 45 degrees

render_object()

virtual void BallBase::render_object ( SDL_Renderer * renderer )

pure virtual

Pure virtual method to render the ball.

Must be implemented by derived classes to draw their specific ball shape

Parameters

renderer

The SDL renderer to use for drawing

Implemented in ClassicBall, SquareBall, and TriangleBall.

reset()

void BallBase::reset ( )

virtual

Resets the ball to the center of the screen.

Repositions the ball and randomizes its direction

Repositions the ball to the center and randomizes its direction

set_color()

void BallBase::set_color

(

const SDL_Color &

new_color

)

Sets the color of the ball.

Parameters

new_color

The new color as an SDL_Color

set_game_mode()

void BallBase::set_game_mode

(

int

mode

)

set_position()

void BallBase::set_position	(	float	x,
		float	y )

Sets the position of the ball.

Parameters

x	The new x-coordinate
y	The new y-coordinate

set_velocity()

void BallBase::set_velocity	(	float	velX,
		float	velY )

Sets the velocity of the ball.

Parameters

velX	The new x-velocity component
velY	The new y-velocity component

update()

void BallBase::update ( float travel_time, class Paddle * paddle1, class Paddle * paddle2, User * player1, User * player2 )

virtual

Updates the ball's position and handles collisions.

Moves the ball according to its velocity, checks for collisions with walls and paddles, and updates player scores when necessary.

Parameters

travel_time	Time delta since last update (in seconds)
paddle1	Pointer to the first paddle
paddle2	Pointer to the second paddle
player1	Pointer to the first player's data
player2	Pointer to the second player's data
