為什麼我換手機就可以登GOOGLE了?????????

step1-1

 先下載音樂，並播放

import processing.sound.*;

SoundFile sound1, sound2, sound3;

void setup() {

  size(400, 300);

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

  sound1.play();

}

void draw() {

}

------------------------------------------------------------------------------

step1-2

把音樂下載好，放在資料夾裡面，點滑鼠可以切換音樂

import processing.sound.*;

SoundFile sound1, sound2, sound3;

void setup() {

  size(400, 300);

  textSize(50);

  fill(255,0,0);

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

  sound2 = new SoundFile(this, "Monkey 1.mp3");

  sound1.play();

}

int stage=1;

void draw() {

  background(255);

  if(stage==1){//舞台1

    text("stage 1", 100, 100);

  }else if(stage==2){//舞台2

    text("stage 2", 100, 100);

  }

}

void mousePressed(){

  if(stage==1){

    stage=2;

    sound1.stop();

    sound2.play();

  }else if(stage==2){

    stage=2;

    sound1.stop();

    sound2.play();

  }

}

------------------------------------------------------------------------------

step1-3

簡化剛剛的程式

void setup() {

  size(400, 300);

}

int stage=1;

void draw() {

  background(255,255,0);

  fill(255,0,0);

  textSize(80);

  if(stage==1){//舞台1

    text("stage 1", 100, 100);

  }else if(stage==2){//舞台2

    text("stage 2", 100, 100);

  }

}

void mousePressed(){

  if(stage==1) stage=2;

  else if(stage==2) stage=1;

}

------------------------------------------------------------------------------

step2-1

物體沒有重力會漂走

void setup(){

  size(400,300);

}

float fruitX=200, fruitY=300;//水果的位置

float fruitVX=2, fruitVY=-13;//水果的速度

boolean flying=true;

void draw(){

  background(255,255,0);

  

  ellipse(fruitX, fruitY, 50,50);

  if(flying){//如果在飛，水果的位置會改變

    fruitX += fruitVX;

    fruitY += fruitVY;

    fruitVY += 0.98/3;//重力加速度

  }

}

void keyPressed(){

  flying=false;

}

------------------------------------------------------------------------------

step2-2

給物體重力

void setup(){

  size(400,300);

}

float fruitX=200, fruitY=300;//水果的位置

float fruitVX=2, fruitVY=-13;//水果的速度

boolean flying=true;

void draw(){

  background(255,255,0);

  

  ellipse(fruitX, fruitY, 50,50);

  if(flying){//如果在飛，水果的位置會改變

    fruitX += fruitVX;

    fruitY += fruitVY;

    fruitVY += 0.98/3;//重力加速度

  }

}

void keyPressed(){

  flying=false;

  fruitReset();///重新準備另一發水果

}

void fruitReset(){

  fruitX=random(100,300);

  fruitY=300;//固定高度

  fruitVX=random(-2,+2);

  fruitVY=-13;

  flying=true;

}

------------------------------------------------------------------------------

step2-3

修改一下

//目標: class物件: 每個水果都可以用物件做出來(值、函式)

class Fruit{

  float x,y,vx,vy;

  boolean flying;

  PApplet sketch;//為了讓random可以用，修改一下

  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;//重力加速度

  }

}

Fruit fruit;

void setup(){

  size(400,300);

  fruit = new Fruit(this);//為了讓random可以用，修改一下

}

void draw(){

  background(255,255,0);

  ellipse(fruit.x, fruit.y, 50, 50);

  fruit.update();

}

void keyPressed(){

  fruit.reset();

}

------------------------------------------------------------------------------

step2-4-1

水果的程式

//目標: class物件: 每個水果都可以用物件做出來(值、函式)

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;

  }

}

step2-4-2

主程式

Fruit [] fruits;

void setup(){

  size(400,300);

  fruits = new Fruit[3];

  for(int i=0; i<3; i++){

    fruits[i] = new Fruit(this);//修改一下

  }

}

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();

    }

  }

}
