目標一:做出angry bird遊戲（進階）

1.利用(Week03-1.3)的概念再做延伸

程式碼：

PImage imgBird, imgPig;

float birdX=100,birdY=500;

float birdVX=0 , birdVY=0;

float birdAX=0 , birdAY=0;

float [][]pigx=new float[5][4];  //透過陣列方式增加Pig

float [][]pigy=new float[5][4];

boolean [][]pigAlive=new boolean[5][4];

void setup()

{

  size (800,700);

  imgBird=loadImage("bird.png");

  imgPig=loadImage("pig.png");

  imageMode(CENTER);

    for(int i=0;i<5;i++)//將陣列新增的pig，貼入指定的位置上

  {

      for(int j=0;j<4;j++)

     {

        pigx[i][j]=700-i*100; pigy[i][j]=100+j*100;

        pigAlive[i][j]=true;

     }

  }

}

void draw()

{

    background(255);

    for(int i=0;i<5;i++)    //碰到豬就消失的程式碼，因為float被改成boolean函數

    {

      for(int j=0;j<4;j++)

      {

        if(dist(pigx[i][j],pigy[i][j],birdX,birdY)<100)

        {

          pigAlive[i][j]=false;

        }

       if(pigAlive[i][j])

          image(imgPig,pigx[i][j],pigy[i][j],100,100);

     }

   }

  image(imgBird, birdX,birdY,100,100);

  birdX += birdVX;

  birdY +=birdVY;

  if(birdX<50) {birdX=50; birdVX =-birdVX;}

  if(birdX>width-50) {birdX=width-50; birdVX=-birdVX;}

  if(birdY<50) {birdY=50; birdVY =-birdVY;}

  if(birdY>width-50) {birdY=width-50; birdVY=-birdVY;}

  birdVX += birdAX;

  birdVY += birdAY;

  birdVX *=0.997;

  birdVY *=0.997;

}

void mouseDragged()  //直線運動

{

  birdX=mouseX; birdY=mouseY;

  birdVX=birdVY=birdAX=birdAY=0;

}

void mouseReleased()  //拋物線

{

  birdVX = (100-mouseX)/ 10.0;

  birdVY = (400-mouseY)/ 10.0;

  birdAY = 0.98;

}

2.新增音效

步驟一：按以下路徑點開：速寫本->引用庫文件->添加庫文件

步驟二：下載 "Minim" + " Sound "

步驟三：將音樂檔案拖入程式內

程式碼：

import processing.sound.*;

SoundFile sound;

void setup()

{

  size (800,600);

  sound = new SoundFile(this,"Battle Theme.mp3");

  sound.play();

  sound.loop();

}
