Python

1. Port your implementation of assignment 4 to Python. (Mario, the tubes, fireballs, and Goombas should all behave as in your other versions. You do not need to implement the AI.) Here's some starter code. If you save it to a file named "game.py", then you can execute it with the command "python game.py".

   from typing import Tuple
   import os
   os.environ['PYGAME_HIDE_SUPPORT_PROMPT'] = '1'
   import pygame
   import time
   import pygame.locals as pg
   from time import sleep
   
   class Turtle():
   	def __init__(self) -> None:
   		self.x = 100
   		self.y = 100
   		self.dest_x = self.x
   		self.dest_y = self.y
   		self.image = pygame.image.load("turtle.png")
   
   	def update(self) -> None:
   		if self.x < self.dest_x:
   			self.x += 1
   		if self.x > self.dest_x:
   			self.x -= 1
   		if self.y < self.dest_y:
   			self.y += 1
   		if self.y > self.dest_y:
   			self.y -= 1
   
   	def draw(self, screen: pygame.Surface) -> None:
   		rect_in = self.image.get_rect()
   		w = rect_in[2] - rect_in[0]
   		h = rect_in[3] - rect_in[1]
   		rect_out = (
   			self.x + rect_in[0] - w // 2,
   			self.y - h,
   			self.x + w,
   			self.y)
   		screen.blit(self.image, rect_out)
   
   class Model():
   	def __init__(self) -> None:
   		self.turtle = Turtle()
   
   	def update(self) -> None:
   		self.turtle.update()
   
   	def set_dest(self, pos: Tuple[int, int]) -> None:
   		self.turtle.dest_x = pos[0]
   		self.turtle.dest_y = pos[1]
   
   class View():
   	def __init__(self, model: Model) -> None:
   		screen_size = (800,600)
   		self.screen = pygame.display.set_mode(screen_size,
   			pygame.DOUBLEBUF | pygame.HWSURFACE, 32)
   		self.model = model
   
   	def update(self) -> None:
   		self.screen.fill([0,200,100])
   		self.model.turtle.draw(self.screen)
   		pygame.display.flip()
   
   class Controller():
   	def __init__(self, model: Model) -> None:
   		self.model = model
   		self.keep_going = True
   
   	def update(self) -> None:
   		for event in pygame.event.get():
   			if event.type == pg.QUIT:
   				self.keep_going = False
   			elif event.type == pg.KEYDOWN:
   				if event.key == pg.K_ESCAPE:
   					self.keep_going = False
   			elif event.type == pygame.MOUSEBUTTONUP:
   				self.model.set_dest(
   					pygame.mouse.get_pos())
   		keys = pygame.key.get_pressed()
   		if keys[pg.K_LEFT]:
   			self.model.turtle.dest_x -= 1
   		if keys[pg.K_RIGHT]:
   			self.model.turtle.dest_x += 1
   		if keys[pg.K_UP]:
   			self.model.turtle.dest_y -= 1
   		if keys[pg.K_DOWN]:
   			self.model.turtle.dest_y += 1
   
   print("Use the arrow keys to move. Press Esc to quit.")
   pygame.init()
   m = Model()
   v = View(m)
   c = Controller(m)
   while c.keep_going:
   	c.update()
   	m.update()
   	v.update()
   	sleep(0.02)
   print("Goodbye")
   

FAQ:

1. Q: I'm getting a message about "pygame" not being found. What can I do about that?
   A: I used a package called "pygame". You probably want to use "pip" to install it. Use a search engine to find the exact command to install this package.
