SFML cpp gra kolizje

Question

tutaj link ---> film co sie dzieje

hej, mam taką funkcje do sprawdzania kolizji i generalnie dziala dobrze, ale jesli najezdzam postacia na platforme od gory albo od dolu i cala postac nie znajduje sie jakby w szerokości platformy, to przerzuca mi ja na bok zamiast zostawic na platformie. ktos wie jak to naprawić?

 

void Player::checkCollisions(std::vector<Obstacle> obstacles)
{
	sf::Vector2f playerPos = hitbox.getPosition();

	for (auto& obs : obstacles) {
		sf::FloatRect playerBounds = hitbox.getGlobalBounds();
		sf::FloatRect wallBounds = obs.getObstacle().getGlobalBounds();

		nextPosition = playerBounds;
		nextPosition.left += velocity.x;
		nextPosition.top += velocity.y;

		if (wallBounds.intersects(nextPosition)) {
			//Bottom collision
			if (playerBounds.top < wallBounds.top
				&& playerBounds.top + playerBounds.height < wallBounds.top + wallBounds.height
				&& playerBounds.left < wallBounds.left + wallBounds.width
				&& playerBounds.left + playerBounds.width > wallBounds.left
				)
			{
				this->isPressed = 0;
				velocity.y = 0.f;
				player.setPosition(playerBounds.left, wallBounds.top - playerBounds.height);
				hitbox.setPosition(playerBounds.left, wallBounds.top - playerBounds.height);
			}

			//Top collision
			else if (playerBounds.top > wallBounds.top
				&& playerBounds.top + playerBounds.height > wallBounds.top + wallBounds.height
				&& playerBounds.left < wallBounds.left + wallBounds.width
				&& playerBounds.left + playerBounds.width > wallBounds.left
				)
			{
				velocity.y = 0.f;
				player.setPosition(playerBounds.left, wallBounds.top + wallBounds.height);
				hitbox.setPosition(playerBounds.left, wallBounds.top + wallBounds.height);
			}

			//Right collision
			if (playerBounds.left < wallBounds.left
				&& playerBounds.left + playerBounds.width < wallBounds.left + wallBounds.width
				&& playerBounds.top < wallBounds.top + wallBounds.height
				&& playerBounds.top + playerBounds.height > wallBounds.top
				)
			{
				velocity.x = 0.f;
				player.setPosition(wallBounds.left - playerBounds.width, playerBounds.top);
				hitbox.setPosition(wallBounds.left - playerBounds.width, playerBounds.top);
			}

			//Left collision
			else if (playerBounds.left > wallBounds.left
				&& playerBounds.left + playerBounds.width > wallBounds.left + wallBounds.width
				&& playerBounds.top < wallBounds.top + wallBounds.height
