嗯哼嗯哼，稍微複習一下之前ㄉ東C

PImage img = loadImage("helios.png");

PVector pt = new PVector(10,20,0);

image(img,0,0);

println(pt.x);

//以前要用ㄉ時候

float userX=10,userY=20,userZ=0;

float user2X=30,user2Y=40,user2Z=0;

//現在可以用物件讓它有條理

PVector user = new PVector(10,20,0);

PVector user2 = new PVector(30,40,0);

做憤怒鳥辣！

先弄球球出來

點擊球球會跟著動

放開會彈飛出去
