Adding a Backdrop

Find a suitable image for the backdrop

  1. We have already prepared an backdrop for this tutorial. Locate this image my_first_game/pyscratch/example/getting-started/assets/my_background.jpg. Open it and have a look.

  2. Copy and paste it inside the assets folder.

Your folder now looks like this

├─ my_first_game/
    ├─ pyscratch/
    ├─ assets/
        ├─ player-fish.png
        ├─ my_background.jpg
    ├─ main.py
    ├─ player.py

Reference this image in main.py

Adding a backdrop is as simple as just adding these three lines in main.py before the game start.

# load the image
backdrop_img = pysc.load_image('assets/my_background.jpg') 

# a list of all the backdrop images 
pysc.game.set_backdrops([backdrop_img]) 

# use the backdrop at index 0 (use can switch the backdrop anywhere in the game)
pysc.game.switch_backdrop(0)
In case you have multiple backdrops (not a part of this tutorial): 
# load the images
backdrop_img0 = pysc.load_image('assets/my_background0.jpg') 
backdrop_img1 = pysc.load_image('assets/my_background1.jpg') 
backdrop_img2 = pysc.load_image('assets/my_background2.jpg') 

# a list of all the backdrop images 
pysc.game.set_backdrops([backdrop_img0, backdrop_img1, backdrop_img2]) 

# use the backdrop at index 0 
pysc.game.switch_backdrop(0)

Now your main.py look like this

main.py 
import pyscratch as pysc
import player

# backdrop
backdrop_img = pysc.load_image('assets/my_background.jpg') # load the image(s)
pysc.game.set_backdrops([backdrop_img]) # a list of all the backdrop images 
pysc.game.switch_backdrop(0) # use the backdrop at index 0 


# start the game
screen_height = 720
screen_width = 1280
framerate = 60

pysc.game.update_screen_mode((screen_width, screen_height))
pysc.game.start(framerate)
What you would see in the game
