Make sure the file exists! StarField = ScrollingBackground(screenheight, 'background.png') _visible(0) _caption('Space Age Game') # fix indentation while True: time = clock.tick(framerate)/1000.0 x, y = _pos() for event in (): if event.type = pygame.QUIT: sys.exit() # Set new Background Coordinates and update the screen StarField.UpdateCoords(bg_speed, time) StarField.Show(screen) ()

How to create your own game background code#

First, create a new file named scrolling_background_game.py and then add the code for the ScrollingBackground class as follows: pygame.init() # initialize pygame clock = () screenwidth, screenheight = (480, 640) screen = _mode((screenwidth, screenheight)) # Set the framerate framerate = 60 # Set the background scrolling speed bg_speed = 100 # Load the background image here. Now let’s add all this code to the main loop.

Here, we use the classical mechanics of motion and calculate the distance using speed and time : def UpdateCoords(self, speed_y, time): distance_y = speed_y * time ord += distance_y ord2 += distance_y if ord2 >= 0: ord = self.y_original ord2 = self.y2_original Then we need to update the coordinates of the image so that the background will shift downward the next time we update. To show the background each time we update, we can use the surface.blit method to draw the image in the current coordinates: def Show(self, surface): surface.blit(self.img, ord) surface.blit(self.img, ord2) We can encapsulate the logic for the background scroll in a class by setting the image file and screen height as parameters: class ScrollingBackground: def _init_(self, screenheight, imagefile): self.img = (imagefile) ord = ord2 = self.y_original = ord self.y2_original = ord2 First, we’ll need to display the background when we load the app, and then scroll it vertically by moving the y-axis on each update, as shown in the diagram below:

Now that you know how to add a background, let’s make it more interactive by scrolling it the same way that good old games like 1942 did. Now, let’s run the program on the command line, using: python3 background_picture_game.py You can also get the current mouse position using mouse.get_pos().Pressing the ESC key will exit the game, based on code that listens for exit events.The screen.blit() method draws the image at the initial coordinates.clock.tick(60) (60 FPS) syncs with the frame rate.This main game loop will be inserted after the while True statement, where: Make sure that you have a background.png image in the same folder as the background_picture_game.py file (any picture will do). Sets the screen dimension with t_mode().Make sure the file exists! bg = (os.path.join('./', 'background.png')) _visible(0) _caption('Space Age Game') # fix indentation while True: clock.tick(60) screen.blit(bg, (0, 0)) x, y = _pos() for event in (): if event.type = pygame.QUIT: sys.exit() ()

How to create your own game background series#

For the purpose of learning game development skills, the best approach is to develop a series of small programs that offer just one feature, and then combine them into larger programs when you get more comfortable with the code.Ĭreate a new Python file called background_picture_game.py with the following contents: import pygame import sys import os from pygame.locals import * pygame.init() # initialize pygame clock = () screen = _mode((600, 480)) # Load the background image here. To keep it simple, we’ll create a very basic window with a background picture.

How to create your own game background install#

The first step is to install a version of Python 3 (such as ActivePython 3.8 ), and then install pygame from the command line using pip: python3 -m pip install -U pygame Step 2 – Implement a Background in PyGame

Add a moving sprite tied to mouse movement.

We’re going to create a simple scrolling game using the following steps: You don’t have to develop something complicated or overly engineered – a classic 2D scrolling game will get the ball rolling. This tutorial will teach you a few game development concepts using PyGame, which is a cross-platform set of Python modules designed for writing video games. Now’s the time to give it a try, improve your skills, and have some fun. Stranded at home with lots of time on your hands? Want to learn something new and exciting? If you‘re like most developers, you’ve probably been kicking around a game design in your head.
