simple game program in python code example

Example 1: how to make a game in python

# Set up the screen
# Python 3.7.3 chromebook
# Turtle
import turtle

# Set up the screen
turtle.Screen()
wn = turtle.Screen()
wn.bgcolor("black")
wn.title("Ping Pong game by Aaryan")
wn.setup(width=800, height=600)
wn.tracer(0)

# Paddle A
paddle_a = turtle.Turtle()
paddle_a.speed(0)
paddle_a.color("white")
paddle_a.shape("square")
paddle_a.penup()
paddle_a.goto(-350, 0)
paddle_a.shapesize(stretch_wid = 5, stretch_len = 1)

# Paddle B
paddle_b = turtle.Turtle()
paddle_b.speed(0)
paddle_b.color("white")
paddle_b.shape("square")
paddle_b.penup()
paddle_b.goto(350, 0)
paddle_b.shapesize(stretch_wid = 5, stretch_len = 1)

paddle_aspeed = 20
paddle_bspeed = 20

# Ball
ball = turtle.Turtle()
ball.shape("circle")
ball.color("white")
ball.dy = 2
ball.dx = 2


# Function
def paddle_a_up():
    y = paddle_a.ycor()
    y += paddle_aspeed
    paddle_a.sety(y)

turtle.listen()
turtle.onkey(paddle_a_up, "Up")


def paddle_a_down():
    y = paddle_a.ycor()
    y -= paddle_aspeed
    paddle_a.sety(y)

turtle.listen()
turtle.onkey(paddle_a_down, "Down")

def paddle_b_up():
    y = paddle_b.ycor()
    y += paddle_bspeed
    paddle_b.sety(y)

turtle.listen()
turtle.onkey(paddle_b_up, "w")

def paddle_b_down():
    y = paddle_b.ycor()
    y -= paddle_bspeed
    paddle_b.sety(y)

turtle.listen()
turtle.onkey(paddle_b_down, "s")

# Main game loop
while True:
    wn.update()

Example 2: simple game with python

# 1 - Import library
import pygame
from pygame.locals import *

# 2 - Initialize the game
pygame.init()
width, height = 640, 480
screen=pygame.display.set_mode((width, height))

# 3 - Load images
player = pygame.image.load("resources/images/dude.png")

# 4 - keep looping through
while 1:
    # 5 - clear the screen before drawing it again
    screen.fill(0)
    # 6 - draw the screen elements
    screen.blit(player, (100,100))
    # 7 - update the screen
    pygame.display.flip()
    # 8 - loop through the events
    for event in pygame.event.get():
        # check if the event is the X button 
        if event.type==pygame.QUIT:
            # if it is quit the game
            pygame.quit() 
            exit(0)
