老師第二次解釋矩陣排列圓圈

float birdX=100,birdY=400;

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

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

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

void setup(){

  size(800,600);

  for(int i=0;i<5;i++)

  {

    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()

{

  

  for(int i=0;i<5;i++)

  {

    for(int j=0;j<4;j++)

  {

    fill(255);ellipse(pigx[i][j],pigy[i][j],100,100);

  }

  }

  fill(0);ellipse(birdX,birdY,100,100);

}

播放音樂

新增 sound資料庫

最簡單的播放音樂

import processing.sound.*;

SoundFile sound;

void setup()

{

  

 size(800,600);

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

 sound.play();

 sound.loop();

 }
