1.首先到速寫本的引用文件添加庫文件下載sound

2.以下的程式碼可以播出你下載的音樂


import processing.sound.*;
SoundFile player;

void setup(){
  player = new SoundFile(this,"music.mp3");
  player.play();
}
void draw(){

}

以下如圖

3.以下的程式碼是可以點一下滑鼠，會有氣球出現並往上飄，並且卡在天花板上

PImage imgBalloon;

float []balloonX=new float[200];

float []balloonY=new float[200];

float []balloonSize=new float[200];

int nowN=0;

void setup(){

  size(500,400);

  imgBalloon = loadImage("balloon.jpg");

}

void draw(){

  background(255);

  for(int i=0; i<nowN; i++){

    image(imgBalloon, balloonX[i], balloonY[i], balloonSize[i], balloonSize[i]/2*3);

    if(balloonY[i]>0) balloonY[i]--;

  }

}

void mousePressed(){

   balloonSize[nowN]=100;

   balloonX[nowN]=mouseX-balloonSize[nowN]/2;

   balloonY[nowN]=mouseY-balloonSize[nowN]/2*3;

   nowN++;

}

以下如圖

4.以下程式碼是上面的加強版，只要你按著滑鼠，氣球會從小慢慢變大，都有不同的大小

PImage imgBalloon;

float []balloonX=new float[200];

float []balloonY=new float[200];

float []balloonSize=new float[200];

int nowN=0;

void setup(){

  size(500,400);

  imgBalloon = loadImage("balloon.jpg");

}

void draw(){

  background(255);

  for(int i=0; i<nowN; i++){

    image(imgBalloon, balloonX[i], balloonY[i], balloonSize[i], balloonSize[i]/2*3);

    if(balloonY[i]>0) balloonY[i]--;

  }

  if(mousePressed) setBalloon(balloonSize[nowN-1]*1.01, nowN-1);

}

void setBalloon(float size, int i){

  balloonSize[i]=size;

  balloonX[i]=mouseX-balloonSize[i]/2;

  balloonY[i]=mouseY-balloonSize[i]/2*3;

}

void mousePressed(){

   setBalloon(10, nowN);

   nowN++;

}
