Week03 本田速人的暴走二輪日誌

課程內容1:

匯入一個寶貝球PNG檔

並且跟隨滑鼠

PImage img;

void setup(){

  size(600,800);

  img=loadImage("Poke_Ball.png");

  imageMode(CENTER);

}

void draw(){

  background(255);

  image(img,mouseX,mouseY,100,100);

}

//都是曾經學過的

課程內容2:

加入一個寶貝目標

我選擇稀有神獸-暴鯉龍

PImage imgBall,imgGyar;

float ballX=300,ballY=400,GyarX=300,GyarY=200;

float ballVX=0,ballVY=0;

void setup(){

  size(600,800);

  imgBall=loadImage("Poke_Ball.png");

  imgGyar=loadImage("gyarados.gif");

  imageMode(CENTER);

}

void draw(){

  background(255);

  image(imgGyar,GyarX,GyarY,250,200);

  image(imgBall,ballX,ballY,100,100);

    ballX+=ballVX/2.0;

    ballY+=ballVY/2.0;

}

void mouseMoved(){

  if(mouseY<height*2/3 && bFly==false){

    ballVX=mouseX-pmouseX;

    ballVY=mouseY-pmouseY;

  }else if(mouseY>height*2/3){

    ballX=mouseX;

    ballY=mouseY;

    ballVX=0;

    ballVY=0;

  }

}

但丟出的寶貝球不太擬真

沒有加速跟都不出去的感覺

所以加了幾行程式

PImage imgBall,imgGyar;

float ballX=300,ballY=400,GyarX=300,GyarY=200;

float ballVX=0,ballVY=0;

boolean bFly=false;

void setup(){

  size(600,800);

  imgBall=loadImage("Poke_Ball.png");

  imgGyar=loadImage("gyarados.gif");

  imageMode(CENTER);

}

void draw(){

  background(255);

  image(imgGyar,GyarX,GyarY,250,200);

  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 && bFly==false){

    ballVX=mouseX-pmouseX;

    ballVY=mouseY-pmouseY;

    bFly=true;

  }else if(mouseY>height*2/3){

    ballX=mouseX;

    ballY=mouseY;

    ballVX=0;

    ballVY=0;

    bFly=false;

  }

}
