按下特定按鍵可以播放不同音檔

 text("Input:" + line,50,100);
}
void keyPressed(){
 if(key>='A' && key<='Z') { line += key; da.play();}
 if(key>='a' && key<='z') { line += key; da.play();}
 if(key==BACKSPACE && line.length()>0)
   { line = line.substring(0,line.length()-1);
   ouch.play();
 
}
if(key==ENTER){
 dingdong.play(); 
  }

跟第一節課的結合在一起
void setup(){
 size(400,600); 
 textSize(20);
}
String Q = "hello",A = "";
float x = 100, y = 100;
void draw(){
 background(0);
 text(Q,100,100);
 ellipse(200,550,20,20);
}
void setup(){
 size(400,600); 
 textSize(20);
}
String Q = "hello",A = "";
float x = 100, y = 100;
void draw(){
 background(0);
 text(Q,x,y);
 ellipse(200,550,20,20);
 float dx = (200-x), dy = (550-y), d = sqrt(dx*dx+dy*dy)*3;
 x += dx/d;
 y += dy/d;
}
一點一點往下移動


void setup(){
 size(400,600); 
 textSize(20);
}

void draw(){
 background(0);

 ellipse(200,550,20,20);
 float dx = (200-x), dy = (550-y), d = sqrt(dx*dx+dy*dy)*3;
 x += dx/d;
 y += dy/d;
 if(keyPressed){
  stroke(255,0,0);
  line(200,550,x,y);
 }
}
按下按鍵可以畫紅色的線
