This tutorial requires PyScratch version 2.1.0 or above.

Demo 1: Loading the Sounds

1. Add these two sound files Circus-Theme-Entry-of-the-Gladiators-Ragtime-Version(chosic.com).mp3 and impactMetal_light_004.ogg into the asset folder

├─ my_first_game/
    ├─ tutorial_pack/
    ├─ assets/
        ├─ chest-open.png
        ├─ fish_red_skeleton_outline.png 
        ├─ orange_red_outline.png
        ├─ undersea_bg.png
        ├─ Cat In Space Wallpaper Hq.jpg
        ├─ Circus-Theme-Entry-of-the-Gladiators-Ragtime-Version(chosic.com).mp3
        ├─ impactMetal_light_004.ogg
    ├─ main.py
    ├─ chest.py
    ├─ enemy.py
    ├─ friend.py

2. Put these lines in main.py

main.py

import pyscratch as pysc
from pyscratch import game
import chest, enemy, friend
       
# sound
game.load_sound("hit", "assets/impactMetal_light_004.ogg")
game.load_sound("background", "assets/Circus-Theme-Entry-of-the-Gladiators-Ragtime-Version(chosic.com).mp3")

# backdrops
... 
# starting the game
...

Now you can play the sound by the name.

Demo 2: Play a sound effect when the enemy fish is clicked

Use game.play_sound("hit") to play the sound.

enemy.py

@enemy.when_this_sprite_clicked()
def play_sound_when_clicked():
    """
    when_this_sprite_clicked:
    play a sound
    """
    game.play_sound("hit")

Demo 3: Playing Background Music

We want to play the sound track repeatedly when it finishes. Since the sound track is 2 minutes and 31 seconds long, we wait for 2*60+31 seconds plus an extra 2 seconds for a break.

main.py

# background music
@game.when_game_start()
def play_loop():
    """
    when_game_start:
    Continuously play the background music 
    """
    while True:
        game.play_sound("background", volume=0.3)
        yield 2*60+31 + 2 # or you can just put 153 

# starting the game
...

The game with music on
