互動技術

1.用P語言做出一個會撥放歌曲的程式

程式:

//mp3,wav
//Audio,Sound,Music
import processing.sound.*;
SoundFile player;
SoundFile wavPon;
void setup(){
  player = new SoundFile(this,"dora.mp3");
  player.play();
}
void draw(){

}

2.點擊滑鼠會出現加農砲的聲音

程式:

//mp3,wav
//Audio,Sound,Music
import processing.sound.*;
SoundFile player;
SoundFile wavPon;
void setup(){
  //player = new SoundFile(this,"dora.mp3");
  //player.play();
  wavPon = new SoundFile(this,"pon.wav");
}
void draw(){

}
void mousePressed(){
  wavPon.play();
}

3.做出一個點擊滑鼠會出現氣球且往上飄

程式:

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.jpg");
}
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++;
}

4.氣球可以隨著滑鼠按下的時間慢慢變大

程式:

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.jpg");
}
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++;
}
