 WEEK04

在網路上找圖 再把圖拉到process

設定好圖片大小 就會有圖片了

再找一張去背的圖 在改一些程式碼

就能讓去背圖跟著滑鼠移動了!!

 PImage img;

PImage img2;

void setup()

{

  size (300,225);

  img = loadImage("1.png");

  img2 = loadImage("2.png");

}

int x=0;

void draw()

{

  if(mouseX>200) x--;

  image( img , x, 0);

  image( img2 , mouseX-50/2, mouseY-80/2,50,80);

}

使圓碰到邊界就反彈

float x=250,y=200;
float vx=2,vy=2;
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 mosueReleased()
{
  vx = x-mouseX; vy = y-mouseY;
}
