I added some code to speed up the ball when the player bar is moving at the moment of the collision, with the function speed_up():<\/p>\n

def speed_up():\r\n    global vel_bal\r\n    x, y = pygame.mouse.get_pos()\r\n    if startx == x:\r\n        vel_bal = 1\r\n        print(\"Normal speed\")\r\n    else:\r\n        vel_bal = 2\r\n        print(\"Speed up\")<\/pre>\n
We also added the bricks, but, at the moment they are just images and no collision is detected.<\/p>\n
They are built with this sprite class:<\/p>\n
class Sprite:\r\n    \"Draw Player 2\"\r\n\r\n    def __init__(self, x, y):\r\n        self.x = x\r\n        self.y = y\r\n        self.update()\r\n\r\n    def update(self):\r\n        pygame.draw.rect(screen, GREEN, (self.x, self.y, 50, 10))<\/pre>\n
And then all the bricks are create with this function:<\/p>\n
def create_bricks():\r\n    blist = \"\"\"\r\n10111111\r\n11111011\r\n    \"\"\"\r\n    bricks = []\r\n    h = 20\r\n    w = 0\r\n    for brick in blist[1:-1]:\r\n        if brick == \"1\":\r\n            bricks.append(Sprite(20 + w * 60, h))\r\n            if w > 7:\r\n                w = 0\r\n                h += 20\r\n        w += 1\r\n    return bricks\r\n\r\nbricks = create_bricks()<\/pre>\n
So the bricks list contains all the sprites, that are displayed in the while loop<\/strong> with the update function of every sprite:<\/p>\n
    for brick in bricks:\r\n        brick.update()<\/pre>\n
The whole code<\/h2>\n
