上禮拜的最後步驟，加入音樂所以按下撥放後會有In Game Music.mp3為背景音樂。

import processing.sound.*;

 SoundFile sound1,sound2,sound3;

void setup(){

size(400,300);

sound1=new SoundFile(this,"In Game Music.mp3");

sound1.play();

}

void draw(){

}

放入兩個音樂，同時畫面會出現stage1或是stage2按下滑鼠後能將stage1音樂和畫面停止變換成stage2的畫面和音樂。

import processing.sound.*;

 SoundFile sound1,sound2,sound3;

void setup(){

size(400,300);

sound1=new SoundFile(this,"In Game Music.mp3");

sound2=new SoundFile(this,"Intro Song_Final.mp3");

sound1.play();

}

int stage=1;

void draw(){

 background(255);

 textSize(50);

 fill(255,0,0);

 if(stage==1){

  text("stage 1",100,100);

  }else if (stage==2){

   text("stage 2",100,100);

  }

 

 }

void mousePressed()

{

 if(stage==1){

   stage=2;

   sound1.stop();

   sound2.play();

 }else if(stage==2){

  

   stage=1;

   sound2.stop();

   sound1.play();

 }

}

簡化上面stage1、2更換的程式

import processing.sound.*;

 SoundFile sound1,sound2,sound3;

void setup(){

size(400,300);

sound1=new SoundFile(this,"In Game Music.mp3");

sound2=new SoundFile(this,"Intro Song_Final.mp3");

sound1.play();

}

int stage=1;

void draw(){

 background(255);

 textSize(50);

 fill(255,0,0);

 if(stage==1){

  text("stage 1",100,100);

  }else if (stage==2){

   text("stage 2",100,100);

  }

 

 }

void mousePressed()

{

 if(stage==1) stage=2;

 else if (stage==2) stage=1;

}//簡化

做出一顆白球會移動。

void setup()

{

size(400,300);

}

float fruitX=200,fruitY=150;

float fruitVX=1,fruitVY=-1;

boolean flying=true;

void draw(){

background(255,255,0);

  ellipse(fruitX,fruitY,50,50);

  if(flying){

  fruitX+=fruitVX;

  fruitY+=fruitVY;

  }

}

void keyPressed()

{

  flying=false;

}

修改上面球移動的程式碼，更改速度方向。

void setup()

{

size(400,300);

}

float fruitX=200,fruitY=300;

float fruitVX=2,fruitVY=-13;

boolean flying=true;

void draw(){

background(255,255,0);

  ellipse(fruitX,fruitY,50,50);

  if(flying){

  fruitX+=fruitVX;

  fruitY+=fruitVY;

  fruitVY+=0.98/3;

  }

}

void keyPressed()

{

  flying=false;

  fruitRest();

}

void fruitRest(){

 fruitX=random(100,300);

 fruitY=300;

 fruitVX=random(-2,+2);

 fruitVY=-13;

 flying=true;

}

3-1
球會從上面往下掉，沒有字母而且還無法消除。

class Fruit{

float x,y,vx,vy;

boolean flying;

PApplet sketch;

Fruit(PApplet _sketch){

  sketch=_sketch;

  reset();

 }

  void reset(){

   x=sketch.random(100.0,300.0);

   y=300;

   vx=sketch.random(-2,+2);

   vy=-13;

   flying=true;

  

  }

   void update(){

    x+=vx;

    y+=vy;

    vy+=0.98/3;

   

   }

}

Fruit fruit;

void setup(){

 size(400,400);

 fruit=new Fruit(this);

}

void draw(){

background(255,255,0);

  ellipse(fruit.x,fruit.y,50,50);

  fruit.update();

}

void keyPressed()

{

  fruit.reset();

}

3-2
開一個新的分頁名字是Fruit，當有英文字母的球掉下來，你輸入同樣的字母球就會被消除。

Fruit [] fruits;

void setup(){

size(400,400);

fruits=new Fruit[3];

for(int i=0;i<3;i++){

   fruits[i]=new Fruit(this);

 }

}

void draw(){

background(255,255,0);

for(int i=0;i<3;i++){

   fill(255);ellipse(fruits[i].x,fruits[i].y,50,50);

   textSize(30);

   textAlign(CENTER,CENTER);

   fill(0);text(fruits[i].c,fruits[i].x,fruits[i].y);

   fruits[i].update();

 }

}

void keyPressed(){

for(int i=0;i<3;i++){

   if(keyCode==fruits[i].c){

    fruits[i].reset();

   }

 }

}

Fruit程式碼

String line="ABCDEFGHIJKLMNOPQRSTUVWXYZ";

class Fruit{

float x,y,vx,vy;

boolean flying;

char c;

PApplet sketch;

Fruit(PApplet _sketch){

  sketch=_sketch;

  reset();

 }

  void reset(){

   x=sketch.random(100.0,300.0);

   y=300;

   vx=sketch.random(-2,+2);

   vy=-13;

   flying=true;

   int i=int (random(26));

   c= line.charAt(i); 

  }

   void update(){

    x+=vx;

    y+=vy;

    vy+=0.98/3;

   

   }

}
