1.下載  Sound 範例：

2.開啟範例後，揀選程式碼：

3.選好音樂下載MP3檔，拖曳加入程式碼中，輸入檔名，完成！

點即出現一個氣球：

PImage imgBalloon;

float balloonX, balloonY, balloonSize=0;

void setup(){

  size(500,400);

  imgBalloon = loadImage("Balloon.jpg");

}

void draw(){

  background(255);

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

}

void mousePressed(){

  balloonSize = 100;

  balloonX = mouseX-balloonSize/2;

  balloonY = mouseY-balloonSize/2*3;

}

出現多個氣球，點及氣球上升：

PImage imgBalloon;

float []balloonX=new float[200];  ///點即出現多個氣球

float []balloonY=new float[200];  ///點即出現多個氣球

float []balloonSize=new float[200];  ///點即出現多個氣球

int nowN=0;  ///點即出現多個氣球

void setup(){

  size(500,400);

  imgBalloon = loadImage("Balloon.jpg");

  println("setup");

}

void draw(){

  println(nowN + "draw"); ///顯示第幾顆

  background(255);

  for(int i=0; i<nowN; i++){   ///點即出現多個氣球

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

    if(balloonY[i]>0) balloonY[i]--;  ///點及氣球上升

  }

  if(mousePressed) balloonSize[nowN-1]++;  ///滑鼠按住氣球充氣

}

void mousePressed(){

  balloonSize[nowN] = 100;

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

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

  nowN++;///點即出現多個氣球

  println(nowN); ///點即出現次數

  println("mousePressed"); ///點即出現

}

氣球出現有大有小：

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");

  println("setup");

}

void draw(){

  println(nowN + "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]*1.07,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++;

}
