Week06

1.放入音樂

import processing.sound.*;
SoundFile player;

void setup(){
  player = new SoundFile(this, "aa.mp3");
  player.play();
}
void draw(){

}

2.氣球飄浮往上

PImage imgBalloon;
float []balloonX=new float[200];
float []balloonY=new float[200];
float []balloonSize=new float[200];
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++;
}

3.長按氣球會慢慢變大往上飄

PImage imgBalloon;
float []balloonX=new float[200];
float []balloonY=new float[200];
float []balloonSize=new float[200];
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]--;
 }
 if(mousePressed) setBalloon(balloonSize[nowN-1]*1.01,nowN-1);
}
void setBalloon(float size, int i){
  balloonSize[i]=size;
  balloonX[nowN]=mouseX-balloonSize[i]/2;
  balloonY[nowN]=mouseY-balloonSize[i]/2*3;
}
void mousePressed(){
  
  setBalloon(10,nowN);
  nowN++;
}
