Question

Please help me create a CLASS DIAGRAM for this code:

import pygame
from pygame.sprite import Sprite

class Bullet(Sprite):
"""A class to manage bullets fired from the ship."""
  
def __init__(self, ai_settings, screen, ship):
"""Create a bullet object at the arrows's current position"""
super().__init__()
self.screen = screen
  
#create a cullet rect at (0,0) and then set correct position
self.rect = pygame.Rect(0, 0, ai_settings.bullet_width,ai_settings.bullet_height)
self.rect.centerx = ship.rect.centerx
self.rect.top = ship.rect.top
#store that bullets position as a decimal val
self.y = float(self.rect.y)
  
self.color = ai_settings.bullet_color
self.speed_factor = ai_settings.bullet_speed_factor

def update(self):
"""move the bullet up the screen"""
#update the decimal position of the bullet
self.y -= self.speed_factor
#update the rect position
self.rect.y = self.y
  
def draw_bullet(self):
"""draw the bullet to the screen"""
pygame.draw.rect(self.screen, self.color, self.rect)

Answer 1

Explanation:

The class Bullet extends the Sprite class which is base class for game objects. Hence class diagram should also describe Sprite class
