step01

畫卡片

```java

size(500,500);

rect(100,100, 150,250, 20);//弧度

```

加邊框

```java

size(500,500);

int W=20;

rect(100-W/2,100-W/2, 150+W,250+W, 20);

fill(#A50808);

rect(100,100, 150,250, 20);//弧度

```

複數張卡

```java

void setup()

{

  size(500,500);

}

int W=20;

void draw()

{

  drawCard(100,100);

  drawCard(130,130);

  drawCard(160,160);

}

void drawCard(int x,int y)

{

  fill(255);

  rect(x-W/2,y-W/2, 150+W,250+W, 20);

  fill(#A50808);

  rect(x,y, 150,250, 20);//弧度

}

```

step02

撲克牌

```java

void setup()

{

  size(500,500);

}

int W=20;

void draw()

{

  drawPokerCard(100,100,"S4");

  drawPokerCard(130,150,"H3");

  drawPokerCard(160,200,"D5");

  drawPokerCard(190,250,"CJ");

}

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

{

  fill(255);

  rect(x-W/2,y-W/2, 150+W,250+W, 20);

  fill(#FCC600);

  rect(x,y, 150,250, 20);//弧度

  

  fill(0);

  textSize(40);

  text(face,x,y+40);

}

```

切換成中文字

```java

void setup()

{

  size(500,500);

  PFont font =createFont("標楷體",40);

  textFont(font);

}

int W=20;

void draw()

{

  drawPokerCard(100,100,"黑桃4");

  drawPokerCard(130,150,"紅心3");

  drawPokerCard(160,200,"方塊5");

  drawPokerCard(190,250,"梅花J");

}

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

{

  fill(255);

  rect(x-W/2,y-W/2, 150+W,250+W, 20);

  fill(#FCC600);

  rect(x,y, 150,250, 20);//弧度

  

  fill(0);

  textSize(40);

  text(face,x,y+40);

}

```

紅字黑字

```java

void setup()

{

  size(500,500);

  PFont font =createFont("標楷體",40);

  textFont(font);

}

int W=20;

void draw()

{

  drawPokerCard(100,100,"黑桃4");

  drawPokerCard(130,150,"紅心3");

  drawPokerCard(160,200,"方塊5");

  drawPokerCard(190,250,"梅花J");

}

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

{

  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);

}

```

step03

洗牌

```java

void setup()

{

  size(500,500);

  PFont font =createFont("標楷體",40);

  textFont(font);

  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

}

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);

}
