首先創建視窗 熟悉draw

加上Framecount 做出簡易文字時鐘

利用millis 長出一個時鐘

倒數計時會轉換成時分秒

void setup(){

  size(600,600);

  fill(255);//白色的字

  textSize(80);

}

void draw(){

  background(#075BB2);

  String hh=nf(hour(),2);

  String mm=nf(minute(),2);

  String ss=nf(second(),2);

  text("現在:"+hh+":"+mm+":"+ss,50,100);

  text("下課:15:40:00",50,200);

  

  int now = hour()*60*60 + minute()*60 + second();

  int next =15    *60*60 + 40      *60 + 0;

  int remain = next-now;

  text("剩下:"+remain,50,300);

  hh = nf(remain/60/60%60,2);

  mm = nf(remain/60%60,2);

  ss = nf(remain%60,2);

  text("剩下:"+hh+":"+mm+":"+ss,50,400);

}

顯示圖片

PImage [] img =new PImage[10];

void setup(){

  size (1120,450);

  for(int i=0; i<10;i++) img[i]=loadImage(i+".png");

}

void draw(){

  for(int i=0;i<10;i++){

    int x =(i%5)*224,y=int(i/5)*225;

    image(img[i],x,y);

  }

}

PImage [] img =new PImage[10];

PFont font;

void setup(){

  

  size(1120,450);

  for(int i=0; i<10;i++) img[i]=loadImage(i+".png");

  fill(255);

  font = createFont("標楷體",80);

  textFont(font);

}

void draw(){

  background(#075BB2);

  String hh=nf(hour(),2);

  String mm=nf(minute(),2);

  String ss=nf(second(),2);

  text("現在:"+hh+":"+mm+":"+ss,50,100);

  text("下課:15:40:00",50,200);

  

  int now = hour()*60*60 + minute()*60 + second();//總秒數

  int next = 16   *60*60 + 40      *60 + 0;//總秒數

  int remain = next-now;//剩下的時間 (秒數來算)

  if(remain<0) remain += 24*60*60;

  text("剩下:"+remain, 50,300);

  hh = nf(remain/60/60%60, 2);

  mm = nf(remain/60%60, 2);

  ss = nf(remain%60, 2);

  text("剩下:"+hh+":"+mm+":"+ss, 50,400);

  int x=800;

  while(remain>0){

    int n = remain%10;

    remain = remain / 10;

    image( img[n], x,100,100,100);

    x-=100;

  }
