python - How to create sound of ball bouncing off of bar -

i working on little pong game, wondering on how add together sound game when ball bounces off of 1 of paddles, create sound want.

this code, , sound file have called "blop.wav".

since you're doing in pygame, want utilize pygame.mixer.

see docs, , linked examples, total details, basically, key points are:

call pygame.mixer.init() construct pygame.mixer.sound(file=path_to_wavfile) each wavfile. every time want play sound, phone call thesound.play().

by default, 8 channels; if seek play 9 simultaneous sounds, 1 of them fail play. if want things like, say, stop background loop temporarily free channel sound effect, can handle manually, or can reserve of channels different purposes, etc. usually, basics enough.

which formats pygame.mixer.sound can handle depend on libraries compiled pygame/sdl build. .wav format should there, if don't want rely on that, can utilize stdlib's wave module read file, sound(buffer=…) constructor.
