先(sketch - library -manage lib... - "sound" install)
下載音檔放程式介面，不是資料夾
import processing.sound.*;
SoundFile sound1,s2,s3;
void setup()
{
size(400,300);
textSize(30);
fill(0,255,0);
sound1=new SoundFile(this,"Gong.mp3");
s2=new SoundFile(this,"Freezing.mp3");
sound1.play();
}
int stage=1;
void draw()
{
background(255);
if(stage==1)
{
text("stage 1",100,100);
}
else if(stage==2)
{
text("stage 2",100,100);
}
}
void mousePressed()
{
if(stage==1)
{
stage=2;
sound1.stop();
s2.play();
}
else if(stage==2)
{
stage=1;
s2.stop();
sound1.play();
}
}
2.moving fake fruit
void setup()
{
size(400,300);
}
float fruitx=200,fruity=150;/// fruit coordinate
float fruitvx=1,fruitvy=-1;///fruit speed vx vy
boolean fly=true;///boolean - 成立不成立
void draw()
{
background(255,0,255);
ellipse(fruitx,fruity,50,50);
if(fly)
{
fruitx+=fruitvx;
fruity+=fruitvy;
}
}
void mousePressed()
{
fly=false;
}
3.up and down
void setup()
{
size(400,300);
}
float fruitx=200,fruity=300;/// fruit coordinate
float fruitvx=2,fruitvy=-13;///fruit speed vx vy
boolean fly=true;///boolean - 成立不成立
void draw()
{
background(255,0,255);
ellipse(fruitx,fruity,50,50);
if(fly)
{
fruitx+=fruitvx;
fruity+=fruitvy;
fruitvy+= 0.98/3;///gravity+speed
}
}
void mousePressed()
{
fly=false;
reset();
}
void reset()
{
fruitx=random(100,300);
fruity=300;
fruitvx=random(-2,2);
fruitvy=-13;
fly=true;
}
4.另類寫法?
class FRUIT///class物件:物件生成每個水果(值、函式)
{
float x,y,vx,vy;
boolean fly;
PApplet sketch;///使random 可使用的修改
FRUIT(PApplet _sketch)///建構子:the first thing to do
{
sketch= _sketch;///使random 可使用的修改
reset();
}
void reset()
{
x=sketch.random(100.0,300.0);///使random 可使用的修改
y=300;
vx=sketch.random(-2,2);///使random 可使用的修改
vy=-13;
fly=true;
}
void update()
{
x+=vx;
y+=vy;
vy+=0.98/3;
}
}
FRUIT fruit;
void setup()
{
size(400,300);
fruit =new FRUIT(this);///使random 可使用的修改
}
void draw()
{
background(255,0,255);
ellipse(fruit.x,fruit.y,50,50);
fruit.update();
}
void mousePressed()
{
fruit.reset();
}
5.字母(新增分頁)
(1)week08-5
FRUIT [] fruits;
void setup()
{
size(400,300);
fruits =new FRUIT[3];
for(int i=0;i<3;i++)
{
fruits[i]=new FRUIT(this);///使random 可使用的修改
}
}
void draw()
{
background(255,0,255);
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 mousePressed()
{
for(int i=0;i<3;i++)
{
if(keyCode == fruits[i].c)
{
fruits[i].reset();
}
}
}
(2)fruit
String line="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
class FRUIT
{
float x,y,vx,vy;
boolean fly;
char c;
PApplet sketch;

{

fly=true;
int i=int(random(26));
