1. 播放音樂

  (1) 安裝Sound模組

 Code: 

import processing.sound.*; // 匯入音樂播放的套件

SoundFile player; // 宣告音樂播放器

void setup() {
  // 初始化音樂播放器，並傳入音檔檔名
  player = new SoundFile(this, "Wish_You_d_Come_True.mp3");
  player.play(); // 播放音檔
}

void draw() {
  
}

2. 模擬氣球

 Code: 

PImage imgBallon;
ArrayList<Float> ballonX = new ArrayList<Float>();
ArrayList<Float> ballonY = new ArrayList<Float>();
ArrayList<Float> ballonSize = new ArrayList<Float>();
int nowN = 0; // 存共產生了多少氣球

void setup() {
    size(500, 400);
    imgBallon = loadImage("ballon.png");
}

void draw() {
    background(255);
    
    // 畫全部的氣球
    for (int i=0; i<nowN; i++) {
    image(imgBallon, ballonX.get(i), ballonY.get(i),
            ballonSize.get(i), ballonSize.get(i)/2*3);
    
    // 讓氣球往上飄
    ballonY.set(i, ballonY.get(i)-1);
    if (ballonY.get(i)-1 < 0) ballonY.set(i, 0f);
    }
    
    if (mousePressed) setBallon(nowN-1, ballonSize.get(nowN-1)*1.05);
}

// 設定氣球大小的函數
void setBallon(int i, float size) {
    ballonSize.set(i, size);
    ballonX.set(i, mouseX - ballonSize.get(i)/2);
    ballonY.set(i, mouseY - ballonSize.get(i)/2*3);
    
    print(ballonSize.size());
    print(ballonX.size());
    print(ballonY.size());
    println();
}

void mousePressed() {
    if (mouseButton == LEFT) {
        ballonSize.add(10f);
        ballonX.add(0f);
        ballonY.add(0f);
        
        setBallon(nowN, 10f);
        nowN ++;
        
        } else if (mouseButton == RIGHT) {
        // 點右鍵讓氣球爆炸
        for (int i=0; i<nowN; i++) {
            if (mouseX > ballonX.get(i) && mouseX < ballonX.get(i)+ballonSize.get(i)
                && mouseY > ballonY.get(i) && mouseY < ballonY.get(i)+ballonSize.get(i)) {
            ballonSize.set(i, 0f);
            }
        }
    }
}
