做一個可移動的橫向卷軸圖

PImage img;

PImage img2;

void setup(){

size(800,500);

img = loadImage("image.png");

img2 = loadImage("logo.jpg");

}

int x=0;

void draw(){

  if(mouseX>700)x--;

image(img , x , 0);

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

}

做一個會彈跳的球

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 || x<0)vy = -vy*0.85;

}
