作業(一) 圈會左右移動

int ballX=300,ballY=300;

int vx = -2;

void setup()

{

   size(700,400);

}

void draw()

{

  background(255);

  ellipse(ballX,ballY,30,30);

  ballX+=vx;

  if(ballX<0) vx=+2;

  if(ballX>700)vx=-2;

}

作業(二) 圈會彈跳

float ballX=100,ballY=300;

float vx = +2, vy=-10;

void setup()

{

   size(700,400);

}

void draw()

{

  //background(255);

  ellipse(ballX,ballY,30,30);

  ballX += vx;

  ballY += vy;

  vy += 0.98;

  if(ballX<0+15)  vx = -vx*0.9;

  if(ballX>700-15)vx = -vx*0.9;

  if(ballY<0+15)  vy = -vy*0.9;

  if(ballY>400-15)vy = -vy*0.9;

}

作業(三) 圈會彈跳，摩擦力=0會停下來

float vx = +2, vy=-10;

void setup()

{

   size(700,400);

}

void draw()

{

  //background(255);

  ellipse(ballX,ballY,30,30);

  ballX += vx;

  ballY += vy;

  if(ballX<0+15)  vx = -vx*0.9;

  if(ballX>700-15)vx = -vx*0.9;

  if(ballY<0+15)  vy = -vy*0.9;

  if(ballY>400-15)

  {

    vy = -vy*0.9;

    vx = vx*0.9;

    ballY=400-15;

  }

  vy += 0.98;

}

作業(四) 馬力歐 (可上下左右移動)

PImage ImgMario;

float marioX=100,marioY=100;

float marioVX=0,marioVY=0;

void setup()

{

   size(500,500);

   ImgMario = loadImage("11.jpg");

}

void draw()

{

  //background(255);

  rect(0,200,500,50);

  image(ImgMario,marioX,marioY,100,100);

  marioX += marioVX;

  marioY += marioVY;

  if(marioY<=100) marioVY +=0.9;

  else marioY=100;

}

void keyPressed()

{

  if(keyCode==RIGHT) marioX+=3;

  if(keyCode==LEFT) marioX-=3;

  if(keyCode==UP) 

  {

    marioVY = -15;

  }

}

***圖片網址方法(二)***(1)另存文件到桌面(2)在文件中新增文件，並且命名為data(3)上網下載圖片到data(4)圖片網址=圖片名稱.jpg/png

作業(五) 

PImage ImgMario;

float marioX=100,marioY=100;

float marioVX=0,marioVY=0;

void setup()

{

   size(500,500);

   ImgMario = loadImage("11.jpg");

}

void draw()

{

  //background(255);

  rect(0,200,500,50);

  image(ImgMario,marioX,marioY,100,100);

  marioX += marioVX;

  marioY += marioVY;

  if(softBreak==1) marioVX*=0.9;

  if(marioY<=100) marioVY +=0.9;

  else marioY=100;

}

int softBreak;

void keyPressed()

{

  if(keyCode==RIGHT) 

  {

    marioVX+=3;

    softBreak=0;

  }

  else if(keyCode==LEFT)

  {

    marioVX-=3;

    softBreak=0;

  }

  else if(keyCode==UP) 

  {

    marioVY = -15;

  }

}
