 置入圖片

PImage img;----------------------------------------宣告圖片

size(700,466);--------------------------------------畫布大小

img = loadImage("image.jpg");------------------讀取圖片

image(img,0,0);------------------------------------圖片位置

置入2張圖片

PImage img;

PImage img2;

size(700,466);

img = loadImage("image.jpg");

img2 = loadImage("image2.png");

image(img,0,0);

image(img2,0,-25,150,100);---------------------後面2數為圖片大小

大圖不動小圖動

PImage img;
PImage img2;
void setup()
{
  size(700,466);
  img = loadImage("image.jpg");
  img2 = loadImage("image2.png");
}
void draw()
{
  image(img,0,0);
  image(img2,mouseX,mouseY-25,150,100);---------讓圖片跟著滑鼠走
}

腳色向右走背景隨之移動

腳色向右走

背景圖隨之滾動

PImage img;

PImage img2;

void setup()

{

  size(700,150);

  img = loadImage("123.jpg");

  img2 = loadImage("456.png");

}

int x=0;

void draw()

{

  if(mouseX>500)x--;---------------------------------------當腳色超出這個範圍 背景開始移動

  image(img,x,0,1200,150);

  image(img2,mouseX-25,mouseY-25,50,50);

}

彈力球

float x=250, y=250;
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;--------------------當碰到邊界就反彈
  if(y>400 || y<0)vy = -vy;
}

控制發射方向

float x=250, y=250;

float vx=0, vy=0;

void setup()

{

   size(500,400); 

}

void draw()

{

  background(255);

  if(mousePressed) line(mouseX,mouseY,x,y);-----------------按下滑鼠瞄準發射方向

  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()----------------------------------------------放開滑鼠發射

{

   vx = x-mouseX;

   vy = y-mouseY;

}

加上重力

float x=250, y=250;

float vx=1.3, vy=-14;

void setup()

{

   size(500,400); 

}

void draw()

{

  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;
