辰 互動概論筆記 week04

 

橢圓往下直直落!

反彈的設定於10,11行

超級好玩 可以彈回去了!!!

可縮放的彈力板

void setup(){

 size (500,500); 

}

float x=250, y=250;

float vx=2.0, vy=-1.5;

float boardX,boardY, boardW=100, boardH=20;

void draw(){

  boardX= mouseX-boardW/2;

   background(#FFFFC2);//背景除殘影

   rect(boardX,boardY,boardW,boardH);//控制的板子

   ellipse(x,y,10,10);//橢圓

   x=x+vx;

   y=y+vy;

   if(x>500)vx=-vx;

   if(y<0)vy=-vy;

   if(x<0)vx=-vx;

   if((y>boardY && y<boardY+boardH) &&

   (x>boardX && x<boardX+boardW)){

      vy=-vy;

      vx+=(mouseX-pmouseX)/2;//滑鼠移速

   }

   if(mousePressed && mouseButton==LEFT) boardW*=1.01;

   if(mousePressed && mouseButton==RIGHT) boardW *=0.99;

}

------------------------------------------

下棋

擺設棋盤樣式 用了兩個迴圈

運用陣列決定黑子白子

void setup(){

 size(500,500); 

}

int [] [] go = {

   {0,0,0,0,0,0,0,0,1},

   {0,0,0,0,0,0,0,0,1},

   {0,1,0,0,0,0,0,0,1},

   {0,0,0,0,1,0,1,0,1},

   {0,0,0,0,0,0,0,0,1},

   {0,0,0,0,0,0,0,2,1},

   {0,0,0,0,0,0,0,2,1},

   {0,0,0,0,0,0,2,0,1},

   {0,0,0,0,0,2,0,0,1},

};

int N=0;

void mousePressed(){

 int j=(mouseX-25)/50;

 int i=(mouseY-25)/50;

 go[i][j]=(N%2==0)? 1:2;

 N++;

}

void draw(){

  background(246,194,108);

  for(int i=1;i<=9;i++){

     line(50,50*i,450,50*i);

     line(50*i,50,50*i,450);

  }

  for(int i=0;i<9;i++){

   for(int j=0;j<9;j++){

    if(go[i][j]==1){

     fill(0);

     ellipse(50+j*50,50+i*50,40,40);

    }else if(go[i][j]==2){

     fill(255);

     ellipse(50+j*50,50+i*50,40,40);

    }

    }

   }

  }
