Walking sound on keyPressed

fboeft

Hello, I am working on a small game for a school project and i am running into a problem with the walking sound. I want it to loop on the walking key pressed and stop when released but im getting this horrible noise. I think its because i keep the key pressed and it loops on itself at a high rate. Can anyone help me?

My Code:

import processing.sound.*;

SoundFile walk;
SoundFile music;

boolean[] keys = new boolean[128];
float x, y;
PVector speed;
int bodySize;
float timer;


void setup() {
  size(1000, 600);
  x = width/2;
  y = height/2;
  bodySize = 50;
  walk = new SoundFile(this, "walk.wav");
  music = new SoundFile(this, "music.mp3");
}

void draw() {
  background(0);
  move();
  ellipse(x, y, bodySize, bodySize);
}


void move() {
  if (keys['a']) {
    x = x-4;
  }
  if (keys['w']) {
    y = y-4;
  }
  if (keys['s']) {
    y = y+4;
  }
  if (keys['d']) {
    x = x+4;
  }
}

void keyPressed() {
  keys[key] = true;
  walk.play();
}

void keyReleased() {
  keys[key] = false;
}

Your keyPressed is restarting the walk noise 30 times a second.

Perhaps the logic should be something like "if walk isn't already playing, play" -- and the keyReleased should be "stop playing walk". I also don't see you actually setting loop().

One possible approach,

   void keyPressed() {
      if(keys[key] == false){
        walk.loop(); //play();
        keys[key] = true;
      }
    }

    void keyReleased() {
      keys[key] = false;
      walk.stop();
    }
