Detailed Description

Power-up that inverts paddle controls temporarily.

This power-up appears as an arrow on screen. When a player hits it with the ball, that player's paddle controls are inverted (up becomes down and vice versa) for a short period of time.

Constructor & Destructor Documentation

InversiblePower()

InversiblePower::InversiblePower	(	int	screen_width,
		int	screen_height )

Constructor for InversiblePower.

Constructs an InversiblePower object.

Parameters

screen_width	Width of the game screen
screen_height	Height of the game screen
screen_width	Width of the game screen
screen_height	Height of the game screen

Initializes the power-up and sets it to active state.

Member Function Documentation

render()

void InversiblePower::render ( SDL_Renderer * renderer )

overridevirtual

Renders the power-up on screen.

Renders the power-up on screen as an arrow.

Parameters

renderer

SDL renderer to draw the power-up

Draws the power-up as a red arrow pointing downward when active. The arrow indicates that this power-up has a negative effect.

Parameters

renderer

SDL renderer to draw the power-up

Reimplemented from Power.

reset()

void InversiblePower::reset ( int screen_width )

overridevirtual

Resets the power-up position.

Resets the power-up to a new random position.

Parameters

screen_width

Width of the game screen for positioning

Places the power-up at a random horizontal position at the top of the screen and assigns it a random color.

Parameters

screen_width

Width of the game screen for positioning

Reimplemented from Power.

update()

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

overridevirtual

Updates the power-up state.

Updates the power-up's state based on game events.

Parameters

time	Delta time since last update
racket1	Pointer to the first paddle
racket2	Pointer to the second paddle
renderer	SDL renderer to draw effects
ball	Pointer to the game ball

Handles the power-up movement, collision detection with the ball, activation of control inversion effect, and timing for effect duration. When the ball collides with this power-up, the controls for the player who last hit the ball are inverted for 3 seconds.

Parameters

time	Delta time since last frame
racket1	First player's paddle
racket2	Second player's paddle
renderer	SDL renderer (unused in this method)
ball	The game ball for collision detection

Reimplemented from Power.

Member Data Documentation

inverse_paddle

bool InversiblePower::inverse_paddle = false

private

repeat

float InversiblePower::repeat

private

Timer for power-up respawn
