畫圖－存檔程式：
void setup(){
  size(600,600);
}
void draw(){
  if(mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
}
void keyPressed(){
  save("now.png");
}

寫完程式碼後，隨意按鍵存檔
檔案與程式碼檔案會存在同一個資料夾

儲存多個不同檔案
void setup(){
  size(600,600);
}
void draw(){
  if(mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
}
int number=0
void keyPressed(){
  //save("now.png");
  save("now_" + number + ".png");
  number++;
}

saveFrame 功能

void setup(){

  size(600,600);

}

void draw(){

  if(mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);

}

//int number=0;

void keyPressed(){

  saveFrame();

  //save("now.png");

  //save("now_" + number + ".png");

  //number++;

}

saveStrings: 存文字檔
String [] names ={"AAA", "BBB", "CCC"};
saveStrings("myClassmateName.txt", names);

loadStrings

Example 1:

Example 2:

滑鼠抓硬幣
程式碼：
PVector [] coins=new PVector[10];
void setup(){
  size(500,500);
  for(int i=0;i<10;i++){
    coins[i]=new PVector (random(500), -random(100));
  }
}
int score=0;
void draw(){
  background(255);
  for(int i=0; i<10; i++){
    fill(255,255,0); ellipse(coins[i].x, coins[i].y, 30,30);
    coins[i].y+=2;
    if(coins[i].y>530) coins[i].y=-random(100,100);
    if(dist(mouseX, mouseY, coins[i].x, coins[i].y)<30){
score+=100; coins[i].y=-random(100);
    }
  }
fill(255,0,0); textSize(30); text("Score:"+score, 200,200);
}

PVector [] coins=new PVector[10]; 

void setup(){

  size(500,500);

  for(int i=0;i<10;i++){

    coins[i]=new PVector (random(500), -random(100));

}

int score=0, life=10, speed=2;

void draw(){

    }

  }

fill(255,0,0); textSize(30); text("Score:"+score +" Life:"+life, 200,200);
