 一開始老師先把一張圖檔直接拉到processing裡去，再來寫上程式碼就可以把圖檔叫出來了

PImage img;

size(440,440);

img= loadImage("dog.jpg");

image(img,0,0);

PImage img;

PImage img2;

size(440,440);

img= loadImage("dog.jpg");

img2=loadImage("dog1.jpg");

image(img,0,0);

image(img2,100,100,54,49);

這段程式碼可以同時塞兩張圖片

PImage img;

PImage img2;

void setup(){

size(440,440);

img= loadImage("dog.jpg");

img2=loadImage("dog1.jpg");

}

void draw(){

image(img,0,0);

image(img2,mouseX-54/2,mouseY-49/2,54,49);

}

這段程式碼可以讓圖片跟著滑鼠移動

PImage img;

PImage img2;

void setup(){

size(400,244);

img= loadImage("longbackgrounp.gif");

img2=loadImage("mario.png");

}

int x=0;

void draw(){

  if(mouseX>300)x--;

image(img,x,0);

image(img2,mouseX-220/2,mouseY-337/2);

}

上面那個代表超出多少就往左抽多少背景圖

float x=250, y=200;

float vx=1.0, vy=2.5;

void setup()

{size(500,400);}

void draw()

{ellipse(x,y, 10, 10);

x+=vx;

y+=vy;

if(x>500 || x<0)vx=-vx;

if(y>400 || y<0)vy=-vy;

}

這隻程式可以模仿牛頓運動定律

float x=250, y=200;

float vx=0, vy=0;

void setup()

{size(500,400);}

void draw()

{

  if(mousePressed)line(mouseX,mouseY,x,y);

  ellipse(x,y, 10, 10);

  ellipse(mouseX,mouseY,10,10);

x+=vx;

y+=vy;

if(x>500 || x<0)vx=-vx;

if(y>400 || y<0)vy=-vy;

}

void mouseReleased()

{

vx=x-mouseX;

vy=y-mouseY;

}

這支我不知道怎麼講，反正自己複製貼上自己看

float x=250, y=200;

float vx=1.3, vy=-14;

void setup()

{size(500,400);}

void draw()

{

  background(255);

  ellipse(x,y, 10, 10);

x+=vx;

y+=vy;

vy+=0.98;

if(x>500 || x<0)vx=-vx*0.85;

if(y>400 || y<0)vy=-vy*0.85;

}

這支程式也可以模仿運動定律
