        Checks if there is a collision between the ball and a paddle.

        The collision is detected based on the proximity of the ball to the paddle along both the x and y axes.
        A collision is considered to have occurred if:
        - The difference in y coordinates of the ball and paddle is less than 60 (close enough vertically).
        - The ball is located in front of the paddle (checked by comparing the absolute x coordinates).
        - The difference in x coordinates of the ball and paddle is less than the collision threshold.

        Args:
            ball (Ball): The ball object.
            paddle (Paddle): The paddle object.

        Returns:
            bool: True if there is a collision, False otherwise.
