今天試試看用程式播音樂

import processing.sound.*;
SoundFile player;

void setup(){
    player = new SoundFile(this,"bob.wav");
    player.play();
}
void draw(){
}

來個氣球往上飄
int nowN=0;
void setup(){
    size (500,400);
    imgBalloon = loadImage("balloon.png");
}
void draw(){
    background(255);
    for(int i=0;i<nowN;i++){
         image(imgBalloon, balloonX[i],balloonY[i],balloonSize[i],balloonSize[i]/2*3);
         if(balloonY[i]>0) balloonY[i]--;
    }
}
void mousePressed(){
     balloonSize[nowN]=100;
     balloonX[nowN]=mouseX-balloonSize[nowN]/2;
     balloonY[nowN]=mouseY-balloonSize[nowN]/2*3;
     nowN++;
}

加入可以放大汽球的圖片

PImage imgBalloon;

float []balloonX=new float[200];

float []balloonY=new float[200];

float []balloonSize=new float[200];;

int nowN=0;

void setup(){

    size (600,800);

    imgBalloon = loadImage("balloon.png");

}

void draw(){

    background(255);

    for(int i=0;i<nowN;i++){

         image(imgBalloon, balloonX[i],balloonY[i],balloonSize[i],balloonSize[i]/2*3);

         if(balloonY[i]>0) balloonY[i]--;

    }

    if(mousePressed) setBalloon(balloonSize[nowN-1]*1.01,nowN-1);

}

void setBalloon(float size ,int i){

   balloonSize[i]=size;

     balloonX[i]=mouseX-balloonSize[i]/2;

     balloonY[i]=mouseY-balloonSize[i]/2*3;

}

void mousePressed(){

     setBalloon(10,nowN);

     nowN++;

}
