程式碼

float ballX=300,ballY=400, pikaX=300, pikaY=200;
float ballVX=0, ballVY=0;
void setup()
{
  size(600,800);

  imgPika=loadImage("Pika.png");
  imageMode(CENTER);
}
void draw()
{
  background(255);

增加拋物線


PImage imgBall, imgPika;
float ballX=300,ballY=400, pikaX=300, pikaY=200;
float ballVX=0, ballVY=0;
boolean bFly=false;
void setup()
{
  size(600,800);
  imgBall=loadImage("Pokeball.png");
  imgPika=loadImage("Pika.png");
  imageMode(CENTER);
}
void draw()
{
  background(255);
  image(imgPika, pikaX, pikaY, 100,100);
  image(imgBall, ballX, ballY, 100,100);
  if(bFly)
  {
  ballX+=ballVX/2.0;
  ballY+=ballVY/2.0;
  ballVY += 0.98;
  }
}
void mouseMoved()
{
  if(mouseY<height*2/3 && ballVY==0)
  {
    ballVX=mouseX-pmouseX;
    ballVY=mouseY-pmouseY;
    bFly=true;
  }
  else if(mouseY>height*2/3)
  {
    ballX=mouseX;
    ballY=mouseY;
    ballVX=0;
    ballVY=0;
    bFly=false;
  }
}

增加縮小的視覺感


PImage imgBall, imgPika;
float ballX=300,ballY=400, pikaX=300, pikaY=200;
float ballVX=0, ballVY=0;
float ballZscale;
boolean bFly=false;
void setup()
{
  size(600,800);
  imgBall=loadImage("Pokeball.png");
  imgPika=loadImage("Pika.png");
  imageMode(CENTER);
}
void draw()
{
  background(255);
  image(imgPika, pikaX, pikaY, 100,100);
  image(imgBall, ballX, ballY, 100/ballZscale,100/ballZscale);
  if(bFly)
  {
  ballX+=ballVX/2.0;
  ballY+=ballVY/2.0;
  ballVY += 0.98;
  ballZscale += 0.03;
  }
}
void mouseMoved()
{
  if(mouseY<height*2/3 && ballVY==0)
  {
    ballVX=mouseX-pmouseX;
    ballVY=mouseY-pmouseY;
    bFly=true;
  }
  else if(mouseY>height*2/3)
  {
    ballX=mouseX;
    ballY=mouseY;
    ballVX=0;
    ballVY=0;
    bFly=false;
    ballZscale=1.0;
  }
}
