 week03    卡牌遊戲(二)

1.新增一個 myShuffle的涵式使其送到滑鼠事件裡能重新洗牌

(1)在setup裡呼叫        myShuffle();

(2)新增 myShuffle()涵式

```c

void myShuffle(){

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

  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);

  ///取整數 0...12，所以要+1

 }

```

(3)新增滑鼠事件

```c

 void mousePressed(){

  myShuffle();

}

```

2.利用迴圈印出52張牌出來，並設定一行10張牌

```c

void setup(){

  size(700,700);

}

void draw(){

  background(#FFFFF2);

  for(int i=0;i<52;i++)

  {

    int x=(i%10)*60;  ///除法10餘數,個位數

    int y=int (i/10)*120;  ///十位數

    rect(x,y,60,120);

  }

}

```

3.增加牌面，寫一個陣列把花色寫上去，暫時先用黑桃代替所有

```c

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",

  "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"

};

void draw(){

  background(#FFFFF2);

  for(int i=0;i<52;i++)

  {

    int x=(i%10)*60;  ///除法10餘數,個位數

    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);

  }

}

```

4.精簡程式，將各個花色設定好，並調整文字大小和印在牌面上的位置

```c

void setup(){

  size(800,700);

  PFont font = createFont("標楷體",16);

  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",

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

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

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

};

void draw(){

  background(#FFFFF2);

  for(int i=0;i<52;i++)

  {

    int x=(i%10)*60;  ///除法10餘數,個位數

    int y=int (i/10)*120;  ///十位數

    fill(255);  rect(x,y,60,120);

    if(faces[i].indexOf("紅心")==-1 && faces[i].indexOf("方塊")==-1)  fill(0);

    else fill(255,0,0);

    fill(0);    text(faces[i],x+10,y+60);

  }

}

```

5.新增mousePressed，使其每按一次滑鼠便隨機洗牌且不會重複重複

```c

void mousePressed(){

  int a =int(random(52));

  int b =int(random(52));

  //目標:faces[a] vs. faces[b]交換

  String temp =faces[a];

  faces[a]=faces[b];

  faces[b]=temp;

}

```

6.拿week03_1的程式來修改，把week03_5的String[]、mousePressed代替原本程式，最終滑鼠按一下樸克牌便可重新洗牌且部會重複

```c

void setup(){

  size(500,500);

  PFont font = createFont("標楷體",40);

  textFont(font);

  myShuffle();

 }//shuffle是洗牌的英文

 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",

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

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

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

};

 void myShuffle(){

  for(int k=0;k<10000;k++){

    int a =int(random(52));

    int b =int(random(52));

    //目標:faces[a] vs. faces[b]交換

    String temp =faces[a];

    faces[a]=faces[b];

    faces[b]=temp;

  }

  face1 = faces[0];

  face2 = faces[1];

  face3 = faces[2];

  face4 = faces[3];

 }

 void mousePressed(){

  myShuffle();

}

String face1,face2,face3,face4;

void draw()

{

  drawCard(100,100,face1);

  drawCard(130,150,face2);

  drawCard(160,200,face3);

  drawCard(190,250,face4);

}///牌面:黑桃 Spade、紅心 Heart、方塊 Dimond、梅花 Club

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

{

  int W=20;

  fill(255);

  rect(x-W/2,y-W/2,150+W,250+W,20);

  fill(#39EA13);

  rect(x,y,150,250,20);

  //fill(0);

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

  else fill(0);  ///黑色

  textSize(40);

  text(face,x,y+40);

}

```
