PImage(讀入圖檔):

Ex1:

size(1100,800);

PImage img;

img = loadImage("image.png");

image(img,0,0);

Ex2:

添加第二張照片

size(1100,800);

PImage img;

PImage img2;

img = loadImage("image.png");

img2= loadImage("image2.png");

image(img2,100,100,80,80);

image(img,0,0);

Ex3:

PImage img;

PImage img2;

void setup(){

  size(1100,800);

  img = loadImage("image.png");

  img2= loadImage("image2.png");

}

void draw(){

  image(img,0,0);

  image(img2,mouseX-80/2,mouseY-80/2,80,80);

  

}

視窗碰撞:

Ex1:

float x=250,y=200;

float vx=1.0,vy=4.5;

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;

}

Ex2:彈弓彈射

float x=250,y=200;

float vx=0,vy=0;

void setup(){

 size(500,400); 

}

void draw(){

  background(255);

  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; 

}

Ex3:

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;

}
