Member Function Documentation

collision()

bool Power::collision

(

BallBase *

ball_type

)

const

Checks for collision between the power and the ball.

Parameters

ball_type

The ball object

Returns

true if collision detected, false otherwise

Parameters

ball_type

Pointer to the ball object

Returns

true if collision detected, false otherwise

render()

void Power::render ( SDL_Renderer * renderer )

virtual

Renders the power on screen.

Parameters

renderer

SDL renderer for drawing

Draws a colored rectangle representing the power if it's active

Parameters

renderer

SDL renderer for drawing

Reimplemented in InversiblePower, and InvisiblePower.

reset()

void Power::reset ( int screen_width )

virtual

Resets the power-up to a new random position.

Resets the power to a new random position.

Parameters

screen_width

The width of the game screen

Reimplemented in InversiblePower, and InvisiblePower.

set_effect_is_active()

void Power::set_effect_is_active

(

bool

active

)

set_is_active()

void Power::set_is_active

(

bool

active

)

Sets the active state of the power-up.

Parameters

active

The new active state

update()

void Power::update ( float time, Paddle * racket1, Paddle * racket2, SDL_Renderer * renderer, BallBase * ball )

virtual

Updates the power's position and effect.

Updates the power's position and checks for collision with the ball.

Virtual method that updates the game's parameters based on power effects

Parameters

time	Time delta since last update
racket1	Pointer to first paddle
racket2	Pointer to second paddle
ball_pos_x	Ball's X position
ball_pos_y	Ball's Y position
ball_radius	Ball's radius
renderer	SDL renderer for drawing

Handles power movement, collision detection, and effect application/duration

Parameters

time	Time delta since last update
racket1	Pointer to first paddle
racket2	Pointer to second paddle
ball	The ball object
renderer	SDL renderer for drawing

Reimplemented in InversiblePower.
