 PImage img;

//圖片,聲音

void setup(){

  size(500,500);

  img=loadImage("exampleimg.jpg");

}//img = loadImage("網址.jpg")

//把圖檔,拉到程式裡面

void draw(){

  image(img,0,0);

}

數字比圖片大會多灰色部分

PImage img1,img2;

//圖片,聲音

void setup(){

  size(500,500);

  img1=loadImage("123.jpg");

  img2=loadImage("456.jpg");

}//img = loadImage("網址.jpg")

//把圖檔,拉到程式裡面

void draw(){

  image(img1,0,0,500,500);

  image(img2,mouseX,mouseY,100,100);

}

讓蝴蝶(img2)跟著滑鼠

可使用PPT的去背功能

圖會跟在滑鼠右下角，所以調整位置到滑鼠中間

或用程式imageMode()來指定位置

播聲音要使用函式庫

import ddf.minim.*;

Minim minim;

AudioPlayer player;

void setup(){

  size(512, 200, P3D);

  

  // we pass this to Minim so that it can load files from the data directory

  minim = new Minim(this);

  

  // loadFile will look in all the same places as loadImage does.

  // this means you can find files that are in the data folder and the 

  // sketch folder. you can also pass an absolute path, or a URL.

  player = minim.loadFile("groove.mp3");  

  player.play();

}

播放內建的GROOVE聲音

import ddf.minim.*;

Minim minim;

AudioPlayer doo,re,mi,fa,so;

void setup()

{

  size(500,500);

  minim = new Minim(this);

  doo = minim.loadFile("do.wav");

  re = minim.loadFile("re.wav");

  mi = minim.loadFile("mi.wav");

  fa = minim.loadFile("fa.wav");

  so = minim.loadFile("so.wav");

}

void keyPressed(){

  if(key=='1'){doo.rewind();doo.play();}

  if(key=='2'){re.rewind();re.play();}

  if(key=='3'){mi.rewind();mi.play();}

  if(key=='4'){fa.rewind();fa.play();}

  if(key=='5'){so.rewind();so.play();}

}

做一個類似鋼琴的程式，用12345來控制

下周做用滑鼠控制的鋼琴
