4.做一顆能拉的寶貝球

PImage img;

void setup(){

   size(800,600);

   img=loadImage("pokeball.png");

   imageMode(CENTER);

}

void draw(){

  background(0,255,0);

  image(img,mouseX,mouseY,100,100);

}

5.加入Pokemon，並讓球能丟出去

PImage imgBall,imgMew;

float ballX=300,ballY=400,mewX=300,mewY=200;

float ballVX=0,ballVY=0;

void setup(){

   size(600,800);

   imgBall=loadImage("pokeball.png");

   imgMew=loadImage("mew.png");

   imageMode(CENTER);

}

void draw(){

  background(0,255,0);

  image(imgMew,mewX,mewY,100,100);

  image(imgBall,ballX,ballY,100,100);

  ballX+=ballVX/1.5; ballY+=ballVY/1.5;

}

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.加入重力加速度

PImage imgBall,imgMew;

float ballX=300,ballY=400,mewX=300,mewY=200;

float ballVX=0,ballVY=0;

boolean bFly=false;

void setup(){

   size(600,800);

   imgBall=loadImage("pokeball.png");

   imgMew=loadImage("mew.png");

   imageMode(CENTER);

}

void draw(){

  background(0,255,0);

  image(imgMew,mewX,mewY,100,100);

  image(imgBall,ballX,ballY,100,100);

  if(bFly){

  ballX+=ballVX/1.5;ballY+=ballVY/1.5;

  ballVY+=0.45;

  }

}

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;

  }

}
