點擊滑鼠洗牌

```java

void setup()

{

  size(500,500);

  PFont font =createFont("標楷體",40);

  textFont(font);

  myShuffle();

}

void myShuffle()

{

  String [] flower={"黑桃","紅心","方塊","梅花"};//陣列

  face1=flower[int(random(4))]+int(random(13)+1);

  face2=flower[int(random(4))]+int(random(13)+1);

  face3=flower[int(random(4))]+int(random(13)+1);

  face4=flower[int(random(4))]+int(random(13)+1);

  //int取整數 0...12所以要加1

}

void mousePressed()

{

  myShuffle();

}

String face1,face2,face3,face4;

void draw()

{

  drawPokerCard(100,100,face1);

  drawPokerCard(130,150,face2);

  drawPokerCard(160,200,face3);

  drawPokerCard(190,250,face4);

}

void drawPokerCard(int x,int y,String face)

{

  int W=20;

  fill(255);

  rect(x-W/2,y-W/2, 150+W,250+W, 20);

  fill(#FCC600);

  rect(x,y, 150,250, 20);//弧度

  

  if(face.indexOf("黑桃")==-1 && face.indexOf("梅花")==-1) fill(#FF0000);

  else fill(0);//黑字

  textSize(40);

  text(face,x,y+40);

}

```

做52張牌

```java

void setup()

{

  size(700,700);

}

void draw()

{

  background(#94FCBD);

  for(int i=0;i<52;i++)

  {

    int x=(i%10)*60; //除以10餘數，個位數

    int y=int(i/10)*120; //十位數

    rect(x,y,60,120);

  }

}

```

step02

顯示52張牌的字

```java

void setup()

{

  size(700,700);

  PFont font =createFont("標楷體",10);

  textFont(font);

}

String []faces=

{

  "黑桃A","黑桃2","黑桃3","黑桃4","黑桃5","黑桃6","黑桃7","黑桃8","黑桃9","黑桃10","黑桃J","黑桃Q","黑桃K",

  "黑桃A","黑桃2","黑桃3","黑桃4","黑桃5","黑桃6","黑桃7","黑桃8","黑桃9","黑桃10","黑桃J","黑桃Q","黑桃K",

    int y=int(i/10)*120; //十位數

    fill(255); rect(x,y,60,120);

    fill(0); text(faces[i],x+25,y+80);

  }

}

```

52張牌優化

```java

void setup()

{

  size(800,600);

  PFont font =createFont("標楷體",16);

  textFont(font);

}

String []faces=

    else fill(255,0,0);

    text(faces[i],x+10,y+60);
