1.下載processing 3.2.1

2.下載chrome app:vysor

3.小畫家載入寶貝球

4.讓寶貝球丟出去抓噴火龍

PImage imgBall, imgFire;
float ballX=300,ballY=400, fireX=300, fireY=200;
float ballVX=0, ballVY=0;
void setup(){
  size(600,800);
  imgBall=loadImage("Poke_Ball.png");
  imgFire=loadImage("Fire.png");
  imageMode(CENTER);
}
void draw(){
  background(255);
  image(imgFire, fireX, fireY, 200,200);
  image(imgBall, ballX, ballY, 100,100);
  ballX+=ballVX/2.0; ballY+=ballVY/2.0;
}
void mouseMoved(){
  if(mouseY<height*2/3 && ballVY==0){
    ballVX=mouseX-pmouseX;
    ballVY=mouseY-pmouseY;
  }else if (mouseY>height*2/3){
    ballX=mouseX; ballY=mouseY;
    ballVX=0; ballVY=0;
  }
}

5.寶貝球可以使用拋物線了

PImage imgBall, imgFire;

float ballX=300,ballY=400, fireX=300, fireY=200;

float ballVX=0, ballVY=0;

boolean bFly=false;

void setup(){

  size(600,800);

  imgBall=loadImage("Poke_Ball.png");

  imgFire=loadImage("Fire.png");

  imageMode(CENTER);

}

void draw(){

  background(255);

  image(imgFire, fireX, fireY, 200,200);

  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;

  }

}

6.寶貝球會隨著拋出去的位置變小了

PImage imgBall, imgFire;

float ballX=300,ballY=400, ballZscale=1.0, fireX=300, fireY=200;

float ballVX=0, ballVY=0;

boolean bFly=false;

void setup(){

  size(600,800);

  imgBall=loadImage("Poke_Ball.png");

  imgFire=loadImage("Fire.png");

  imageMode(CENTER);

}

void draw(){

  background(255);

  image(imgFire, fireX, fireY, 200,200);

  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;

  }

}
