一、製作Angry Bird 小遊戲

二、修正小鳥位置 將其加入滑鼠正中心

imageMode(CENTER);

三、加入重力加速度

程式碼:

PImage imgBird, imgPig;

void setup(){

  size(800,600);

  imgBird=loadImage("bird.png");

  imgPig=loadImage("ppig.png");

  imageMode(CENTER);  //將小鳥圖放到滑鼠正中央

}

float birdX = 400, birdY = 300; //小鳥位置

float birdVX = 0, birdVY = 0; //小鳥初速度

float birdAX =0, birdAY = 0; //小鳥加速度

void draw(){

  background(255); //將殘影刪除

  image(imgPig, 400, 300, 100, 100); //(圖片, X位置, Y位置, 寬, 長)

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

  line(birdX, birdY, 400,300); //劃線

  birdX += birdVX; //給小鳥速度

  birdY += birdVY; //給小鳥速度

  birdVX += birdAX;//給小鳥加速度

  birdVY += birdAY;//給小鳥加速度

}

void mouseDragged(){

  birdX=mouseX; //小鳥跟著滑鼠走

  birdY=mouseY; //小鳥跟著滑鼠走

  birdVX=birdVY=birdAX=birdAY=0;//歸零數值

}

void mouseReleased(){

  birdVX = (400-mouseX)/10.0;//彈出後給小鳥的速度

  birdVY = (300-mouseY)/10.0;//彈出後給小鳥的速度

  birdAY = 0.98;//Y值的重力加速度

}

四、當小鳥碰到豬的時候豬消失

程式碼:

PImage imgBird, imgPig;

void setup(){

  size(800,600);

  imgBird=loadImage("bird.png");

  imgPig=loadImage("ppig.png");

  imageMode(CENTER);

}

float birdX = 400, birdY = 300;

float birdVX = 0, birdVY = 0;

float birdAX =0, birdAY = 0;

float pigx=700, pigy=100;

boolean pigAlive=true;

void draw(){

  background(255);

  if(pigAlive) image(imgPig, pigx, pigy, 100, 100);

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

  if (dist(pigx, pigy, birdX, birdY)<100){

    pigAlive=false;

  }

  line(birdX, birdY, 400,300);

  birdX += birdVX;

  birdY += birdVY;

  birdVX += birdAX;

  birdVY += birdAY;

}

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;

}

五、讓小鳥不會跑出邊界

程式碼:

PImage imgBird, imgPig;

void setup(){

  size(800,600);

  imgBird=loadImage("bird.png");

  imgPig=loadImage("ppig.png");

  imageMode(CENTER);

}

float birdX = 400, birdY = 300;

float birdVX = 0, birdVY = 0;

float birdAX =0, birdAY = 0;

float pigx=700, pigy=100;

boolean pigAlive=true;

void draw(){

  background(255);

  if(pigAlive) image(imgPig, pigx, pigy, 100, 100);

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

  if (dist(pigx, pigy, birdX, birdY)<100){

    pigAlive=false;

  }

  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;

}

六、小朋友下樓梯

程式碼:

void setup(){

  size(600,500);

}

int boardX=227, boardY=400;

int kidX=300, kidY=250;

void draw(){

 background(0);

 rect(boardX, boardY, 200, 50);

 rect(kidX, kidY, 50, 50);

 if(kidX>boardX-50 && kidX<boardX+200 && kidY>boardY-50)

 {

   

 }

 else kidY++;

 

 kidX=mouseX;

}
