Traffic Racer Game in Python with Source Code

Traffic Racer Game in Python with Source Code

Traffic Racer Game is developed in Python Programming Language and it is a desktop application.

This Traffic Racer Game in Python is free to download the open source code and it is created for beginners who want to learn Python.

This project system used a Pygame and Random function. Pygame is a cross-platform set of Python modules designed for writing video games.

This Traffic Racer Game has a task record containing image documents, audio sound documents, and a Python content file (TrafficRacer.py).

The gameplay interaction Graphics is sufficient and the controls are excessively basic for the clients.

Discussing the gameplay interaction, all the playing techniques are too basic you should simply avoid the vehicle from the gigantic traffic. Here, the client needs to avoid the vehicle from different vehicles so as to pick up score focuses.

The player needs to race as conceivable on the grounds that the more you race, the more the score focuses. There are all 3 lives for a player.

At whatever point the player contacts different vehicles or accidents, the current score gets put away as the top score and the player needs to restart once more.

The principle target of this game is to score focuses however much as could reasonably be expected.

Before you start on how to create a Traffic Racer Game in Python, make sure that you have PyCharm IDE and Pygame installed on your computer.

By the way, if you are new to Python programming and don’t know what Python IDE to use, I have here a list of Best Python IDE for Windows, Linux, and Mac OS that will suit you. I also have here How to Download and Install the Latest Version of Python on Windows.

How to Create a Traffic Racer Game in Python.

Importing Random Module

In the code given below. which is for the random() function, which generates random numbers between 0 and 1.

import random

Importing Pygame Module

The code given below, which is pygame library is an open-source module for the Python programming language specifically intended to help you make games and other multimedia applications.

Pygame can run across many platforms and operating systems. (Python Source Code for Traffic Racer Game)

import pygame

Importing Sys Module

In the code given below, which is for the function of the sys module. We will use sys.exit to exit the program.

import sys

This module is for the exit

In the code given below, which is for the function of the exit module. (Python Source Code for Traffic Racer Game)

def Exit():
pygame.quit()
sys.exit()

This module is for the key shortcut

In the code given below, which is for the function of keys shortcut. This is to wait for the player to press any key.

def Press_Key_shortcut(): # waiting for player to press any key
while True:
for event in pygame.event.get():
if event.type == QUIT:
Exit()
if event.type == KEYDOWN:
if event.key == K_ESCAPE: # escape quits
Exit()
return

This module is for the player crash

In the code given below, which is for the function of player crash on the game.(Python Source Code for Traffic Racer Game)

car['rect'].move_ip(0, car['speed'])
elif counter_reverse:
car['rect'].move_ip(0, -5)
elif slowing_reverse:
car['rect'].move_ip(0, 1)

for car in opponent[:]:
if car['rect'].top > screen_height:
opponent.remove(car)

This module is for the scoreboard

The code given below, is for the function of scoreboard use in a game.

 txt_objects('SCORE: %s' % (score), fontsize, screen_display_window, 128, 0)
txt_objects('TOP SCORE: %s' % (highest_scores), fontsize, screen_display_window, 128, 20)
txt_objects('REST LIFE: %s' % (counting_seconds), fontsize, screen_display_window, 128, 40)

screen_display_window.blit(player_car_photo, gamer_Rect)

for car in opponent:
screen_display_window.blit(car['surface'], car['rect'])

pygame.display.update()

This module is for the game over-screen

In the code given below, which is for the function of game over screen in the game.

pygame.mixer.music.stop()
counting_seconds = counting_seconds - 1
game_over_music.play()
time.sleep(1)
if (counting_seconds == 0):
chuckle.play()
txt_objects('GAME OVER', fontsize, screen_display_window, (screen_width / 3), (screen_height / 3))
txt_objects('PRESS ANY KEY TO PLAY AGAIN.', fontsize, screen_display_window, (screen_width / 3) - 80, (screen_height / 3) + 30)
pygame.display.update()
time.sleep(2)
Press_Key_shortcut()
counting_seconds = 3
game_over_music.stop()
