C++ SFML Kolizja kuli z paletką (gra typu Arkanoid)

Question

Cześć!

Od pewnego czasu uczę się biblioteki SFML. W ramach nauki piszę grę typu Arkanoid.

Zrobiłem już piłkę, paletkę, lecz nie wiem jak zrobić kolizję między nimi. Oto mój kod:

using namespace sf;

int main()
{
	Map map;
	map.screen();
    return 0;
}

class Map
{
public:



void Map::screen()
{
	Ball::setBall();
	Paddle::setPaddle();
	Map collision;
	RenderWindow window{ VideoMode(1280, 720), "Pong" };
	window.setFramerateLimit(60);
	Event event1;
	for (;;)
	{
		checkCollision::collisionRight();
		checkCollision::collisionTop();
		checkCollision::collisionLeft();
		checkCollision::collisionBottom();

		ifCollision();

		window.clear(Color::Yellow);

		window.pollEvent(event1);
		if (event1.type == Event::Closed)
		{
			window.close();
			break;
		}

		Ball::show();
		Paddle::update();

		window.draw(Ball::circle);
		window.draw(Paddle::rocket);
		

		window.display();
	}
}
};

class Paddle
{
public:

RectangleShape rocket;

const float width{ 200.0f };
const float height{ 22.0f };

float a;
float b;

Vector2f paddleSpeed{ a, b };

void set_size()
{
	rocket.setPosition(650, 640);
	rocket.setSize(Vector2f(this->width, this->height));
	rocket.setFillColor(Color::Cyan);
	rocket.setOrigin(width / 2.f, height / 2.f);
}

void draw(RenderTarget& target, RenderStates state)const
{
	target.draw(this->rocket, state);
}

void update()
{
	paddleX = 640;
	paddleY = 650;
	this->rocket.move(this->paddleSpeed);
	if (Keyboard::isKeyPressed(Keyboard::Key::Left) && this->Left() > 0)
		this-> paddleSpeed.x = -12.0;
	else if (Keyboard::isKeyPressed(Keyboard::Key::Right) && this->Right() < 1280)
		this-> paddleSpeed.x = 12.0;
	else 
		this-> paddleSpeed.x = 0;
}

float Left()
{
	return this->rocket.getPosition().x - rocket.getSize().x/2.f;
}

float Right()
{
	return this->rocket.getPosition().x + rocket.getSize().x/2.f;
}

float Top()
{
	return this->rocket.getPosition().y - rocket.getSize().y / 2.f;
}

float Bottom()
{
	return this->rocket.getPosition().y + rocket.getSize().y / 2.f;
}
};

class Ball
{
public:
float ballX;
float ballY;
CircleShape circle;

const float r{ 20.0f };
const float ballSpeed{ 3.3f };
Vector2f speed{ ballSpeed, ballSpeed };

void Ball::setBall()
{
	ballX = 640.0;
	ballY = 360.0;

	circle.setPosition(ballX, ballY);
	circle.setRadius(r);
	circle.setFillColor(Color::Red);
	circle.setOrigin(this->r, this->r);
}

void Ball::draw(RenderTarget& target, RenderStates state)const
{
	target.draw(this->circle, state);
}

void show()
{
	circle.move(speed);
	if (this->Left() < 0)
		speed.x = 20;
	else if (this->Right() > 1280)
	{
		speed.x = -20;
	}

	if (this->Top() < 0)
	{
		speed.y = 20;
	}
	else if (this->Bottom() > 720)
	{
		speed.y = -20;
	}
}

float Left()
{
	return this->circle.getPosition().x - circle.getRadius();
}

float Right()
{
	return this->circle.getPosition().x + circle.getRadius();
}

float Top()
{
	return this->circle.getPosition().y - circle.getRadius();
}

float Bottom()
{
	return this->circle.getPosition().y + circle.getRadius();
}

};

Jak to zrobić?

To mój pierwszy projekt w SFML, więc mogą być błędy.

Pozdrawiam.
