Each platform of our game is nothing but a cube with a static rigid body. However, since we will create several instances with these components, it is convenient to define a class to avoid repeating this kind of instantiation:

class Platform(GameObject):
    def __init__(self, x, y, width, height):
        super(Platform, self).__init__(x, y)
        color = (0.2, 1, 0.5, 1)
        self.add_components(Cube(color, size=(width, height, 2)),
                            BoxCollider(width, height))

In platformer games, it is common that the player is able to collect some items that give valuable resources. In our game, when the character hits one of these pickups, its ammo is incremented by five units.
