一、今日課程:優化憤怒鳥和小朋友下樓梯

(一)讓憤怒豬出現多個

程式碼:

PImage imgBird, imgPig;

float birdX = 400, birdY = 300;

float birdVX = 0, birdVY = 0;

float birdAX =0, birdAY = 0;

float [][]pigx=new float[5][4];//宣告豬X,Y位置陣列

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

boolean [][]pigAlive=new boolean[5][4];//每隻豬存活陣列

void setup(){

  size(800,600);

  imgBird=loadImage("bird.png");

  imgPig=loadImage("ppig.png");

  imageMode(CENTER);

  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;//每隻豬產生的位置

    }

   

  }

}

void draw(){

  background(255);

  for(int i=0;i<5;i++){

    for(int j=0;j<4;j++){

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

      pigAlive[i][j]=false;//鳥碰到每隻豬讓豬消失

      }

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

    }

  }

  

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

  

  line(birdX, birdY, 400,300);

  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>height-50){birdY=height-50; birdVY= -birdVY;}

  

  

  birdVX += birdAX;

  birdVY += birdAY;

  birdVX *= 0.995;

  birdVY *= 0.995;

}

void mouseDragged(){

  birdX=mouseX; 

  birdY=mouseY;

  birdVX=birdVY=birdAX=birdAY=0;

}

void mouseReleased(){

  birdVX = (400-mouseX)/10.0;

  birdVY = (300-mouseY)/10.0;

  birdAY = 0.98;

}
