 1-1 先練習畫一張卡片

code:

size(500,500);

int W=25;

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

fill(#6AFFA4);//顏色

rect(100,100,150,250,20);

1-2 畫三張卡片，自己寫一個drawCard函式來使用

code:

void setup(){

  size(500,500);

}

int W=25;

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(#FF00F2);

rect(x,y,150,250,20);

}

2-1 修改剛剛的函式，改成drawPokerCard，並給卡片編號

code:

void setup(){

  size(500,500);

}

int W=25;

void draw(){

  drawPokerCard(100,100,"S4");

  drawPokerCard(130,130,"H3");

  drawPokerCard(160,160,"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(#FF00F2);

rect(x,y,150,250,20);

fill(0);

textSize(40);

text(face,x,y+40);

}

2-2 增加Font用來宣告標楷體 並把編號改成花色

code:

void setup(){

  size(500,500);

  PFont font = createFont("標楷體",40);

  textFont(font);

}

int W=25;

void draw(){

  drawPokerCard(100,100,"黑桃4");

  drawPokerCard(130,130,"紅心3");

  drawPokerCard(160,160,"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(#FF00F2);

rect(x,y,150,250,20);

fill(0);

textSize(40);

text(face,x,y+40);

}

2-3 修改不同花色的顏色

code:

void setup(){

  size(500,500);

  PFont font = createFont("標楷體",40);

  textFont(font);

}

int W=25;

void draw(){

  drawPokerCard(100,100,"黑桃4");

  drawPokerCard(130,130,"紅心3");

  drawPokerCard(160,160,"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(#FF00F2);

rect(x,y,150,250,20);

//fill(0);

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

else fill(0);

textSize(40);

text(face,x,y+40);

}

3-1 寫一個亂數(random)使卡片隨機產生

code:

void setup(){

  size(500,500);

  PFont font = createFont("標楷體",40);

  textFont(font);

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);

}

String face1,face2,face3,face4;

void draw(){

  drawPokerCard(100,100,face1);

  drawPokerCard(130,130,face2);

  drawPokerCard(160,160,face3);

  drawPokerCard(190,250,face4);

}

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

int W=25;

fill(255);

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

fill(#FF00F2);

rect(x,y,150,250,20);

//fill(0);

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

else fill(0);

textSize(40);

text(face,x,y+40);

}
