撥放音樂 加上有anrybird
程式碼:
import ddf.minim.*;
Minim minim;
AudioPlayer player;
PImage imgBird;
void setup(){
  size(500,400);
  minim=new Minim(this);
  player=minim. loadFile("song.mp3");
  player.play();
  imgBird=loadImage("bird.png");//圖檔如果沒有放好,會當掉 pointer
  imageMode(CENTER);//以正中心,當座標
}
float birdX=100, birdY=300, oldX, oldY, vx=0, vy=0;//之前的鳥在哪裡
boolean bMoving=false;//if(判斷) ex. if(bMoving)...
void draw(){
  background(255);//清背景
  image(imgBird, birdX,birdY,100,100);
  if(bMoving) line(birdX,birdY, oldX,oldY);
  birdX+=vx; birdY+=vy;
  if(birdX>450 || birdX<50) vx = -vx*0.95;
  if(birdY>350 || birdY<50) vy = -vy*0.95;
}
void mouseReleased(){
  if(bMoving){
    bMoving=false;
    vx=(oldX-mouseX)/10; vy=(oldY-mouseY)/10;// 0.1倍
  }
}
void mousePressed(){
  if( dist(mouseX,mouseY, birdX,birdY)<50){
    oldX=birdX; oldY=birdY;
    bMoving=true;
  }
}
void mouseDragged(){
  if(bMoving) {
    birdX=mouseX; birdY=mouseY;
  }
}
